   今天

   today

   空气

   air

   感觉

   feel; seem

   很沉闷

   heavy and stuffy

   空气质量

   air quality

   可能

   may; might

   很差

   very poor

   More detail

   今天 means “today” and places the time at the start of the utterance. It can be used directly before the situation being described: 今天很冷 means “It is cold today.” 空气 means “air.” It is a noun and can stand alone or combine with another noun to form a specific expression. In 空气质量, it identifies what kind of quality is being discussed. 感觉 means “feel” or “seem” here. The pattern 主语 + 感觉 + 描述 presents a sensory impression: 空气感觉很沉闷 means “the air feels very stuffy.” In another sentence, 这件衣服感觉很舒服 means “This piece of clothing feels comfortable.” 很沉闷 describes the air as very stuffy or oppressive. 很 commonly intensifies an adjective or descriptive word; it does not need to be translated as “very” in every natural Chinese sentence. 沉闷 can describe an unpleasantly stuffy atmosphere or a dull, oppressive feeling, so its exact English rendering depends on what it describes. 空气质量 is the noun phrase “air quality.” It is formed from 空气 (“air”) plus 质量 (“quality”). The same noun-combination pattern appears in examples such as 水质量, “water quality,” when that expression is appropriate in context. 可能 expresses possibility: “may” or “might.” In 空气质量可能很差, it comes before the description and indicates that poor quality is possible, rather than asserting it as certain. For example, 明天可能下雨 means “It may rain tomorrow.” 很差 means “very poor” here. 差 is the descriptive word meaning “poor” or “bad” in this evaluation, and 很 intensifies it. A useful contrast is 很好, “very good,” though the appropriate evaluation depends on the thing being described. Together, 今天 sets the time, 空气感觉很沉闷 says that the air feels very stuffy, and 空气质量可能很差 adds a possibility about its quality. The whole utterance therefore means: “The air feels heavy today, and air quality may be poor.”

2. 那做户外运动可能不是个好主意。

   Outdoor exercise might not be a good idea, then.

   那

   then; so

   做

   do; engage in

   户外运动

   outdoor exercise

   可能

   might; possibly

   不是

   is not; be not

   个

   general measure word

   好

   good

   主意

   idea

   More detail

   那 appears first and works here as a discourse connector meaning “then” or “so,” linking this conclusion to the preceding situation. It is not being used here as a demonstrative meaning “that.” Example: 那我们走吧。 — “Then let’s go.” 做 means “to do” or “to engage in.” In 做户外运动, it introduces the activity of doing outdoor exercise. Its form does not change for person or number. Example: 我喜欢做运动。 — “I like exercising.” 户外运动 is a noun phrase meaning “outdoor exercise” or “outdoor sports.” 户外 means “outdoors/outdoor,” and 运动 means “exercise” or “sport”; together they name the activity. Here the phrase is the activity being considered, not a specific exercise session. 可能 means “might” or “possibly.” Placed before the predicate, it expresses possibility rather than certainty: 可能不是 means “might not be.” Example: 他可能今天不来。 — “He might not come today.” 不是 is the negative form of 是 (“to be”), meaning “is not” in this sentence. It negates the classification of the activity as a good idea. In Chinese, 不 normally comes directly before 是 in this pattern. 个 is a common measure word used in the pattern 是个 + noun, as in “be a ….” It does not by itself assert a numerical count here. Example: 这是个问题。 — “This is a problem.” 好 means “good.” It modifies the following noun in 好主意, meaning “good idea.” The opposite in a simple quality contrast is 坏 (“bad”): 好主意 — “good idea”; 坏主意 — “bad idea.” 主意 means “idea” or “plan.” The combination 好主意 is a reusable noun phrase meaning “good idea.” Example: 这是个好主意。 — “This is a good idea.” Taken together, 做户外运动 names the activity under consideration, 可能 adds uncertainty, and 不是个好主意 says that the activity does not qualify as a good idea. 那 connects this judgment to the preceding circumstances, so the whole utterance means: “Then, doing outdoor exercise might not be a good idea.”

3. 我本来打算去公园跑步。

   I was planning to run in the park.

   我

   I; me

   本来

   originally

   打算

   plan; intend

   去

   go

   公园

   park

   跑步

   run; jog

   More detail

   我 is the first-person singular pronoun, “I/me.” It refers to the speaker in this utterance. Unlike plural 我们 (“we/us”), it does not include another participant. 本来 marks an original or initial state, plan, or expectation. Here it presents the running plan as the speaker’s original intention; it does not by itself say whether the plan was later carried out. A useful pattern is 本来 + plan/state, as in 我本来想休息 (“I originally wanted to rest”). 打算 is a verb meaning “to plan” or “to intend.” The form does not change for the speaker or for singular versus plural subjects: 我打算 and 他们打算 both use 打算. A reusable pattern is 打算 + action, for example, 她打算明天出发 (“She plans to leave tomorrow”). 去 is the verb “to go.” In 去公园跑步, it introduces movement toward a place and is followed by the destination 公园; the activity after the destination explains the purpose of going. This gives the reusable pattern 去 + place + activity, as in 去图书馆学习 (“go to the library to study”). 公园 means “park.” It is a noun and can follow a place-related verb such as 去: 去公园 means “go to the park.” In the fixed sentence, it is the destination, not the activity. 跑步 means “to run” or “to jog,” treating running as an activity. It functions as the action intended at the park. In another sentence, 我每天跑步 means “I run every day”; the time expression changes, but the verb remains 跑步. Together, 我本来打算 means “I originally planned,” and 去公园跑步 means “to go to the park to run.” The whole utterance therefore means: “I was originally planning to go to the park to run,” naturally expressed in the supplied translation as “I was planning to run in the park.”

4. 如果污染让你感到不舒服，就改做室内运动吧。

   If pollution bothers you, choose an indoor workout instead.

   如果

   if

   污染

   pollution

   让

   make; cause

   感到

   feel

   不舒服

   uncomfortable

   就

   then; in that case

   改做

   switch to doing

   室内

   indoor

   运动

   exercise; workout

   吧

   suggestion particle

   More detail

   如果 introduces a condition: “if …”. It commonly pairs with 就 later in the sentence: 如果 A，就 B means “if A, then B.” Example: 如果下雨，就别出门。 — “If it rains, then don’t go out.” 污染 means “pollution” here. It is a noun and can be used as the subject of an action or effect, as in 空气污染 (“air pollution”). 让 means “to make” or “to cause” someone to experience a result. The pattern 让 + person + verb or description expresses that the subject causes that person to do or feel something. Here, 污染让你感到不舒服 means “pollution makes you feel uncomfortable.” 感到 means “to feel” in the sense of experiencing a feeling or condition. It is often followed by an adjective or another description, as in 感到高兴 (“feel happy”). In this sentence, 你 is the person who experiences the condition; 让 marks pollution as the cause. 不舒服 means “uncomfortable” or “unwell.” 不 negates the following description, so 不舒服 is the negative form of 舒服 (“comfortable”). Example: 我今天不舒服。 — “I don’t feel well today.” 就 marks the consequence of the condition introduced by 如果. It can be understood here as “then” or “in that case”; it does not mean that the action happens immediately in time. 改做 means “switch to doing” something instead. 改 contributes the idea of changing the plan, while 做 means “do” here. The pattern 改做 + activity is useful when replacing one activity with another. Example: 天气太热，我们改做室内游戏。 — “It’s too hot, so we’ll switch to an indoor game.” 室内 means “indoor” or “inside.” It describes a location or type associated with being inside, as in 室内活动 (“indoor activity”). 运动 means “exercise” or “workout” here. It can refer broadly to physical activity rather than one specific sport. In 室内运动, it forms the noun phrase “indoor workout/exercise.” 吧 is a sentence-final particle that makes the utterance sound like a suggestion or gentle recommendation. Thus 改做室内运动吧 is a suggestion to switch to an indoor workout, not a bare command. Together, 如果污染让你感到不舒服 sets the condition “if pollution makes you feel uncomfortable.” 就改做室内运动吧 gives the suggested consequence: “then switch to an indoor workout.” The complete utterance means: “If pollution bothers you, choose an indoor workout instead.”

5. 我可以去健身房，虽然那里没有公园那么放松。

   I could use the gym, although it feels less relaxing than the park.

   我可以

   I can / may

   去

   go

   健身房

   gym

   虽然

   although

   那里

   there

   没有 … 那么

   not as … as

   公园

   park

   放松

   relaxed

   More detail

   我可以 means “I can/may” here and presents going as an available option. 可以 is a modal placed before the action; it can express ability, permission, or a feasible option depending on context. For example, 我可以进去吗？ means “May I go in?” 去 means “go.” It commonly comes before a destination: 去学校 means “go to school.” In this sentence, 去 introduces 健身房, the destination. 健身房 means “gym.” The compound combines 健身 (“exercise/keep fit”) with 房 (“room/place”); learn the whole compound as the ordinary word for a gym. Example: 我在健身房锻炼。 — “I work out at the gym.” 虽然 means “although.” It introduces a situation that contrasts with the main statement and is commonly paired with 但是 (“but”), although the paired word may be omitted when the contrast is clear. Here, the contrast begins after the option of going to the gym. 那里 means “there” and refers to the place being discussed in the fixed meaning: the gym. 那 indicates something at a distance from the speaker, and 里 marks an interior or location; the compound functions as a location pronoun. This form does not itself specify who is at that place. 没有……那么 forms the comparison “not as … as.” 没有 means that something lacks or does not reach a stated standard, while 那么 marks the comparison degree. The pattern is A 没有 B 那么 + adjective: 今天没有昨天那么冷。 — “Today is not as cold as yesterday.” 公园 means “park.” In the comparison, it is the standard against which the gym is evaluated. Example: 这个公园很安静。 — “This park is quiet.” 放松 means “relaxed” here, describing how the place feels. The same word can also be used as a verb meaning “to relax” or “to unwind,” so its role depends on the sentence. For example, 周末我喜欢放松。 — “I like to relax on weekends.” Together, 我可以去健身房 says “I could use/go to the gym,” with 可以 presenting that as an available option. 虽然那里没有公园那么放松 adds the contrast: the gym is not as relaxing as the park. The whole utterance therefore means, “I could use the gym, although it feels less relaxing than the park.”

6. 在室内锻炼比吸入质量差的空气更健康。

   Training indoors is healthier than breathing poor air.

   在室内

   indoors

   锻炼

   exercise

   比

   than

   吸入

   breathe in

   质量差的

   poor-quality

   空气

   air

   更健康

   healthier

   More detail

   在室内 means “indoors” here. 在 marks a location, and 室内 means the inside of a room or building. The location phrase can be reused before an activity: Example: 在室外跑步。 — “Run outdoors.” 锻炼 is a verb meaning “to exercise” or “to work out.” In this sentence, 在室内锻炼 is an activity phrase, “exercise indoors.” Example: 我每天锻炼。 — “I exercise every day.” 比 introduces the thing used for comparison. The pattern is A 比 B + adjective: “A is more adjective than B.” Here, A is 在室内锻炼, while B begins with 吸入质量差的空气. 吸入 means “to breathe in” or “to inhale.” It describes air entering the body, so it is more specific than the general activity 呼吸 (“to breathe”). Example: 不要吸入烟雾。 — “Do not inhale smoke.” 质量差的 means “poor-quality.” 质量差 describes something as being of low quality, and 的 lets this description modify the noun that follows. Here it modifies 空气, producing 质量差的空气, “poor-quality air.” Example: 这是质量差的材料。 — “This is poor-quality material.” 空气 is the noun “air.” In this sentence it is the object of 吸入, so 吸入质量差的空气 means “inhale poor-quality air.” 更健康 means “healthier.” The base adjective is 健康, “healthy,” and 更 marks a higher degree in the comparison. Chinese adjectives do not change form for person or number here. Example: 新方法更健康。 — “The new method is healthier.” Putting the parts together, 在室内锻炼 is the first item being compared, and 吸入质量差的空气 is the second. The pattern A 比 B 更健康 states that A is healthier than B. The whole utterance means: “Training indoors is healthier than breathing poor air.”

7. 如果我需要出门走路，应该戴口罩吗？

   Should I wear a mask if I need to walk outside?

   如果

   if

   我

   I; me

   需要

   need

   出门

   go outside; leave home

   走路

   walk; travel on foot

   应该

   should; ought to

   戴口罩

   wear a mask

   More detail

   如果 introduces a condition: “if …”. It normally comes before the condition clause, which is followed by the main clause. Example: 如果下雨，我不出门。 — “If it rains, I won’t go out.” 我 is the first-person pronoun “I/me.” Chinese pronouns do not change for subject case, so the same form can be used for both roles. Example: 我需要帮助。 — “I need help.” 需要 means “need” here. It can be followed directly by a noun or by a verb phrase: 我需要水。 — “I need water”; 我需要休息。 — “I need to rest.” The form does not change for person or time. 出门 is a common verb meaning “go out” or “leave home.” Although 门 means “door,” the compound is normally understood as going outside rather than merely moving through a particular door. Example: 他每天出门上班。 — “He goes out to work every day.” 走路 means “walk” or “travel on foot.” In this sentence it describes going outside on foot. Example: 我喜欢走路。 — “I like walking.” 应该 is a modal meaning “should” or “ought to.” It comes before the action being recommended or considered: 你应该休息。 — “You should rest.” It is different from 需要: 需要 presents something as necessary or needed, while 应该 presents it as advisable or expected. 戴口罩 means “wear a mask.” 戴 is the verb used for putting on or wearing items such as glasses, hats, and masks; 口罩 is “mask.” Example: 进入医院应该戴口罩。 — “You should wear a mask when entering a hospital.” Together, 如果我需要出门走路 sets the condition “if I need to go outside on foot.” 应该戴口罩 asks whether wearing a mask is the advisable action in that situation. The final 吗 turns the statement into a yes-or-no question. Thus the whole utterance means: “Should I wear a mask if I need to walk outside?”

8. 戴口罩会有帮助，而且当地的健康建议可能会提醒你采取额外的防护措施。

   A mask can help, and local health advice may suggest extra precautions.

   戴

   wear; put on

   口罩

   mask

   会有帮助

   can help

   而且

   and; moreover

   当地

   local

   健康建议

   health advice

   可能

   may; possibly

   提醒

   remind; prompt

   你

   you

   采取

   take; adopt

   额外

   extra; additional

   防护措施

   protective measures; precautions

   More detail

   戴 means “to wear” or “to put on” for wearable items. In 戴口罩, it is the verb and 口罩 is the item worn. Example: 出门前戴好口罩。 — “Put on your mask properly before going out.” 口罩 means “mask.” It is a noun: 一个口罩 means “a mask,” while 戴口罩 means “wear a mask.” 会有帮助 expresses a possible or expected helpful result: 会 marks “can/may” here, and 有帮助 means “be helpful.” It does not by itself assert that the result is certain. Example: 休息一下会有帮助。 — “Taking a break may help.” 而且 links this statement to an additional one, meaning “and” or “moreover.” It introduces another relevant point rather than changing the first statement. 当地 means “local,” referring to the place relevant in the situation. It commonly comes before a noun, as in 当地的建议 — “local advice.” 健康建议 is the noun phrase “health advice”: 健康 means “health” or “health-related,” and 建议 means “advice” or “recommendation.” Together they refer to advice concerning health, not necessarily to one particular piece of advice. 可能 means “may” or “possibly.” Before a verb, it presents that action as uncertain: 可能下雨 — “It may rain.” In this sentence, it makes the prompting by the advice possible rather than certain. 提醒 means “remind” or “prompt.” With a person after it, the reusable pattern is 提醒 + person + action, meaning “remind/prompt someone to do something.” Here 提醒你采取…… means “prompt you to take …,” matching the fixed translation’s “suggest.” 你 is the second-person pronoun “you.” It is the person being prompted in this sentence. Chinese 你 does not change form for grammatical gender or number in this use; plural “you” can be written 你们 when that distinction is needed. 采取 means “to take” or “to adopt,” especially when the object is a measure, action, or policy. 采取措施 is a common pattern meaning “take measures.” Example: 我们采取了新的措施。 — “We took new measures.” 额外 means “extra” or “additional.” It modifies 防护措施, so it describes measures beyond the ones already understood in the situation. Example: 需要额外的准备。 — “Additional preparation is needed.” 防护措施 means “protective measures” or “precautions.” 防护 describes protection, and 措施 means measures or steps; together they form a noun phrase. It is the object of 采取 in this sentence. Putting the sentence together: 戴口罩会有帮助 means “Wearing a mask can help.” 而且 adds a second point: 当地的健康建议可能会提醒你采取额外的防护措施 means “local health advice may prompt you to take extra precautions.” The complete utterance is therefore: “A mask can help, and local health advice may suggest extra precautions.”

9. 等空气质量改善后再跑步似乎更安全。

   Postponing the run until the air improves seems safer.

   等 … 后

   once ... then; after ...

   空气质量

   air quality

   改善

   improve

   再

   then; afterward

   跑步

   run

   似乎

   seem; appear

   更安全

   safer

   More detail

   等……后 marks a condition in time: wait until an event has happened, and then do the main action. Here, 等空气质量改善后 means “after waiting for the air quality to improve.” This is a reusable pattern: 等 + event + 后 + main action. Example: 等雨停后再出发。 — “Wait until the rain stops, then set off.” 空气质量 means “air quality.” 空气 is “air,” and 质量 here means “quality”; together they form a noun phrase. Example: 今天的空气质量很好。 — “Today’s air quality is good.” 改善 means “improve” or “get better.” It is the verb used for the change in 空气质量改善, “the air quality improves.” The same form can also be used after another noun: 情况改善了。 — “The situation improved.” 再 means “then” or “afterward” when it places one action after another. In 后再跑步, it reinforces the sequence: first wait for the air quality to improve, then run. It does not mean that the speaker is running repeatedly here. Example: 先休息，再工作。 — “Rest first, then work.” 跑步 means “run” or “go running.” It is a verb-object-style activity expression that can function as the activity being postponed. Example: 我每天早上跑步。 — “I go running every morning.” 似乎 means “seem” or “appear.” It presents the judgment as an impression rather than a definite assertion. Example: 他似乎很累。 — “He seems very tired.” 更安全 means “safer.” 安全 means “safe,” and 更 marks a higher degree, so 更安全 means “safer” or “more safe.” The comparison is understood relative to the alternative of running before the air quality improves; the sentence does not state a numerical degree of safety. Example: 这样做更安全。 — “Doing it this way is safer.” Together, 等空气质量改善后 sets the time condition, 再跑步 places running afterward, and 似乎更安全 gives the speaker’s cautious assessment. The whole utterance means: “Postponing the run until the air improves seems safer.”

10. 这样可以避免运动变成另一个健康问题。

    That keeps exercise from turning into another health problem.

    这样

    this way; like this

    可以

    can; be able to

    避免

    avoid

    运动

    exercise

    变成

    turn into; become

    另一个

    another one

    健康问题

    health problem

    More detail

    这样 means “in this way” or “like this.” Here it points to the method under discussion—postponing the run until the air improves—and introduces the result of using that method. A reusable pattern is 这样 + clause: “in this way, …” 可以 expresses possibility or a feasible result. In this sentence, 这样可以 + verb means “doing this can …,” not a command. For example, 这样可以省时间。 means “This way, you can save time.” 避免 is the verb “to avoid,” used before the unwanted result or action. It commonly introduces something that one prevents from happening: 避免错误 means “avoid mistakes.” 运动 means “exercise” here and functions as the subject of the following change. The same form can also refer more generally to physical activity or, in other contexts, a movement, so its meaning comes from the sentence. 变成 means “become” or “turn into.” 变 means “change,” while 变成 + noun specifies what something changes into. For example, 水变成冰。 means “Water turns into ice.” 另一个 means “another one”: an additional, different instance of something already understood. It modifies the noun phrase 健康问题; it is not the noun being avoided by itself. 健康问题 is the compound noun “health problem”: 健康 means “health” or “healthy,” and 问题 means “problem.” Together, they name a problem connected with health. For example, 睡眠不足可能成为健康问题。 means “Lack of sleep may become a health problem.” The sentence follows the reusable pattern 这样可以避免 A 变成 B: “This way can prevent A from becoming B.” Here, 这样 identifies the method, 可以避免 says that the method can prevent something, 运动 is A, and 另一个健康问题 is B. The complete meaning is: “That keeps exercise from turning into another health problem.”
