Sentence explanations

1. 灯不亮。

   The light does not work.

   灯

   light; lamp

   不亮

   not lit; not working

   More detail

   灯 means “light” or “lamp.” It is a noun; the sentence does not specify whether this refers to a particular kind of light beyond the intended meaning “the light.” 不亮 describes a light that is not lit or is not functioning. 亮 means “to be bright,” “to be lit,” or, for a light, “to work/be on.” 不 placed before a verb or adjective negates it: 不亮 = “is not bright/lit” or, in this context, “does not work.” This is a present-state description, not a past-tense form. Example: 灯亮。 — “The light is on.” Adding 不 gives 灯不亮。 — “The light is not on / does not work.” Together, 灯 is the light being discussed and 不亮 states its current condition, producing “The light does not work.”

2. 你检查开关了吗？

   Did you check the switch?

   你

   you

   检查

   check; inspect

   开关

   switch

   了吗

   did ...?

   More detail

   你 means “you” here. Chinese 你 does not mark singular versus plural; the context must determine the number when that matters. It is the subject of the question. For a respectful or plural “you,” 您 or 你们 may be used in appropriate contexts, but those are different forms. 检查 means “to check” or “to inspect.” It is a verb and can be reused before an object: 检查设备 means “check the equipment.” The form does not change for person or tense. For example, 我检查开关 means “I check the switch” or, depending on context, “I checked the switch.” 开关 means “switch,” the device or control used to turn something on or off. It is a noun. In this sentence it is the object of 检查. A useful related contrast is 开, “to turn on/open,” and 关, “to turn off/close”; those verbs are related to the function of a switch, but 开关 itself names the control. 了吗 is the question ending formed by 了 plus 吗. Here, 了 presents the checking as a completed or newly relevant event, while 吗 turns the statement into a yes-or-no question. The resulting pattern is subject + verb + object + 了吗？, meaning “Has the subject done the action?” or, in natural English for this context, “Did the subject do it?” For example, 你关灯了吗？ means “Did you turn off the light?” The question is about whether the action has happened, not about a fixed past-tense verb form; Chinese verbs generally do not change form for past time. Together, 你 identifies the person being asked, 检查 gives the action, and 开关 gives its object. The final 了吗 asks whether that checking has been completed. Thus the whole utterance means, “Did you check the switch?”

3. 我检查过了，但它还是不亮。

   I checked it, and it still does not work.

   我

   I

   检查过了

   have checked

   但

   but

   它

   it

   还是

   still

   不亮

   not lit

   More detail

   我 is the first-person singular pronoun, “I.” Mandarin pronouns do not change form for grammatical case, so the same form can be used as a subject or object; its role here comes from its position as the checker. 检查过了 means that the checking has already been done. 检查 is the base verb “to check” or “to inspect.” After a verb, 过 marks prior experience of that event: the speaker has checked it before now. It is not simply a general past-tense ending. The final 了 presents the situation as newly established or relevant now, giving the combination the natural sense “I’ve checked it already.” Example: 我看过这部电影。 — “I have seen this film.” 但 connects two contrasting parts and means “but.” The first part reports the check; the following part reports that the problem nevertheless remains. 它 is the third-person pronoun used here for the nonhuman item under discussion, translated as “it.” Mandarin distinguishes human and nonhuman third-person pronouns in writing, but 它 does not encode a grammatical gender distinction. 还是 means “still” here. It shows that the state in the second part continues despite the checking. A useful pattern is 还是 + predicate, as in 它还是不动。 — “It still does not move.” 不亮 says that the item is not lit or does not light up. 亮 is the base descriptive word meaning “bright” or “lit,” and 不 places negation before it. In this sentence, 亮 describes the item's lighting state rather than simply its general visual brightness. For comparison, 灯亮了。 means “The light is on,” while 灯不亮。 means “The light is not on.” Together, 我检查过了 gives the completed-check meaning “I have checked it,” and 但它还是不亮 adds the contrast “but it still does not work” in the fixed translation. The whole utterance therefore means: “I checked it, and it still does not work.”

4. 灯泡可能旧了。

   Maybe the bulb is old.

   灯泡

   bulb

   可能

   maybe; possibly

   旧

   old

   More detail

   灯泡 means “light bulb.” It is a noun referring to the bulb itself. A useful reusable pattern is noun + description, as in 房间很暗。 (“The room is dark.”) 可能 means “maybe” or “possibly” here. It comes before the statement it makes uncertain: 可能 + clause. For example, 他可能在家。 means “He may be at home.” This expresses possibility, not certainty. 旧 means “old” in the sense of not new or worn from use. Here it describes the bulb. It is different from 老, which commonly describes a person’s age and can also describe something that has existed for a long time. For example, 这本书很旧。 means “This book is very old.” The final 了 marks a change of state: the bulb is now old, or has become old. Thus 旧了 is not simply a timeless label; it presents being old as the current resulting state. The pattern 形容词 + 了 can similarly show a change, as in 天黑了。 (“It has become dark.”) Together, 灯泡 + 可能 + 旧了 means “Maybe the bulb is old.” 可能 makes the whole claim tentative, while 旧了 presents the bulb as being in an old state now.

5. 房间现在太暗了。

   The room is too dark now.

   房间

   room

   现在

   now

   太暗

   too dark

   More detail

   房间 means “room” here. It is a noun and can be reused as the subject or object of a sentence. Example: 房间很大。— “The room is large.” 现在 means “now” and places the situation at the present time. It commonly appears before the predicate: 现在很冷。— “It is cold now.” 太暗 describes excessive darkness: 暗 means “dark,” and 太 means “too” or “excessively” before a descriptive word. The form 太暗 is not a comparative adjective like English “darker”; it says that the degree of darkness is beyond what is suitable. Example: 这里太暗了。— “It is too dark here.” Together, 房间 + 现在 + 太暗 means “the room is too dark now.” The final 了 marks the situation as newly changed or now holding as a relevant state; it is not part of the word 暗. Thus 房间现在太暗了。means “The room is too dark now.”

6. 我可以拿一盏小灯来。

   I can bring a small lamp.

   我可以

   I can

   拿

   take or get

   一盏

   one (for lamps)

   小

   small

   灯

   lamp

   来

   come

   More detail

   我可以 combines 我 (“I”) with 可以 (“can; be able to / be permitted to”). Here it expresses the speaker’s ability or offer to do the action that follows; it does not itself mean “bring.” A reusable pattern is 我可以 + verb (“I can …”). For example, 我可以帮你。 means “I can help you.” 拿 is a verb meaning “take” or “get.” In this sentence, its contribution combines with the following 来 to express bringing something toward the relevant deictic point. For example, 请拿一本书来。 means “Please bring a book here.” 一盏 contains 一 (“one”) and 盏, a measure word used with lamps and certain light-producing objects. Unlike an indefinite article, 一 explicitly states the number one here. The reusable pattern is 一 + measure word + noun, as in 一杯水 (“one glass of water”). 小 is the adjective “small.” In Chinese, an adjective can directly modify a noun before it: 小灯 means “small lamp.” The adjective is 小 itself; 灯 is not its base form. For example, 一只小猫 means “one small cat.” 灯 is the noun “lamp” or “light.” In this sentence it refers to the small light being brought. 灯 can also occur in compounds such as 灯泡, “light bulb,” but that is a separate noun from the 灯 used here. 来 means “come” and, after an action verb, can mark movement toward the relevant deictic point, commonly expressed in English with “bring … here.” Thus 拿……来 is a reusable directional pattern meaning “bring/take … here,” with the object placed between the two verbs. Together, 我可以 sets up the speaker’s ability or offer, 拿 names taking or getting the object, 一盏小灯 identifies one small lamp, and 来 gives the movement its toward-here direction. The whole utterance therefore means “I can bring a small lamp.”

7. 我们之后应该换灯泡。

   We should change the bulb later.

   我们

   we; us

   之后

   later; afterward

   应该

   should; ought to

   换

   change; replace

   灯泡

   light bulb

   More detail

   我们 means “we” or “us” here. It is a first-person plural pronoun: the speaker includes themself and at least one other person. Chinese pronouns do not change for subject versus object position, so 我们 can mean either “we” or “us” depending on its role. Example: 我们先走。 — “We’ll leave first.” 之后 means “afterward” or “later.” It places the relevant action after an understood earlier time or event. A reusable pattern is ……之后 (“after …”): 吃饭之后再讨论。 — “Let’s discuss it after eating.” In the fixed sentence, it comes before the modal and verb, so it sets the time for the proposed action. 应该 means “should” or “ought to.” It expresses a recommendation, expectation, or appropriate course of action; it does not by itself assert that the action has happened. It commonly comes before the verb: 你应该休息。 — “You should rest.” 换 means “to change” or “to replace.” In this sentence, it means removing the current bulb and putting in another one. Chinese verbs generally do not change form for person or time, so 换 can be used with different subjects and time expressions: 他们明天换电池。 — “They will replace the battery tomorrow.” 灯泡 means “light bulb.” It is a noun referring to the bulb, rather than the whole lamp. Example: 这个灯泡坏了。 — “This light bulb is broken.” Together, 我们之后应该换灯泡 expresses the recommendation that the speaker and at least one other person should replace the light bulb later: “We should change the bulb later.” The pattern subject + time expression + 应该 + verb + object is reusable, as in 我们明天应该检查门。 — “We should check the door tomorrow.”

8. 换灯泡前先用这盏小灯吧。

   Use the lamp until we replace it.

   换

   replace; change

   灯泡

   light bulb

   前

   before

   先

   first

   用

   use

   这

   this

   盏

   classifier for lamps

   小灯

   small lamp

   吧

   suggestion-softening particle

   More detail

   换 means “replace” or “change” here. It is a verb and does not change form for person or number. In 换灯泡, it takes 灯泡 as the thing being replaced. Example: 换电池 means “replace the battery.” 灯泡 means “light bulb.” It is a noun: 灯 is “lamp/light,” and 泡 is part of this compound, so do not treat the observed word as an inflected form. Example: 灯泡坏了。 means “The light bulb is broken.” 前 means “before” when it follows an event or action. 换灯泡前 therefore means “before replacing the light bulb.” This is a time expression, not a command to replace it immediately. Example: 出门前关灯。 means “Turn off the light before leaving.” 先 means “first” or “for now,” marking the action that should happen earlier in a sequence. Together, 换灯泡前先用... says to use the lamp first, before the replacement. 前 supplies the time relation; 先 highlights the order of the suggested action. 用 means “use.” In 先用这盏小灯, the object being used is 这盏小灯. Example: 先用这个。 means “Use this one first.” 这 is the demonstrative “this.” It identifies the following noun phrase as the one being indicated, but the word itself does not specify the lamp’s size or type. Here it occurs in 这盏小灯, “this small lamp.” 盏 is a measure word used with certain lamps and lights. In 这盏小灯, 这 identifies one lamp, 盏 supplies the measure-word position, and 小灯 names the lamp. A measure word is required in this kind of Chinese demonstrative-noun phrase; 盏 itself does not mean “one” independently here. 小灯 means “small lamp” in this sentence. 小 is the descriptive adjective “small,” modifying the noun 灯 “lamp.” It is not the same noun as 灯泡 “light bulb”; the sentence suggests using this small lamp while the bulb is awaiting replacement. Example: 一盏小灯 means “a small lamp.” 吧 is a sentence-final particle that softens a suggestion. Thus 先用这盏小灯吧 is a gentle “Let’s use this small lamp first” or “Use this small lamp for now,” rather than a bare, forceful command. The particle does not add a separate object or action. The structure is 换灯泡前 (“before replacing the light bulb”) + 先用这盏小灯 (“first use this small lamp”) + 吧 (softened suggestion). As a whole, the utterance suggests using this small lamp until the light bulb is replaced, matching the fixed translation “Use the lamp until we replace it.”
