First up, once of the choices should be 懂, not 董 1. 这课的语法你听（懂）了没有？ 2. A:我叫你，你怎么回答？ B:对不起，我正听录音呢，没有（开）。 Correct answer should be [完]. Translation : Sorry, i'm still listening to the recording, still not (done/finished) 3. A: 你看（见）麦克了没有？ B: 看（见）了，他正在操场跑步呢。 4 A: 老师，这些练习题我做（对）了没有？ B: 你没都做（完),（对）了三道题，做错了道题。 They are both (对). Translation : You did some wrong, only 3 are correct. Main question was (also) answered incorrectly. ** for choosing (完）,the sentence would be ungrammatical unless you reverse [没] and [都] to read [你都没做完], which means "You haven't even finished" 5 快开（上）窗户吧，屋子里太热了。 This one is evil, [上] is correct but [开] is acceptable in casual speech. 6 A:我给你的书你看（完）了没有？ B:还没有看（开）呢。 A is asking if B has finished (完) the book A loaned him. Correct answer is (完) "I haven't finished it yet" 7 这课课文有点儿难。我没有看（董）。 What was your question about on the use of [没有] ?

Just a followup to your comment : Using [没有] at the end of a sentence really depends on what you are trying to say. Unless you can give some examples readers here would be happy to explain, I can help with some examples. Simply just using [没有] by itself is okay, but it usually comes coupled with other words if you want to use it in a QUESTION. 我叫你去买菜 - i told you to go grocery shopping 我叫你去买菜没有？- (casual speech) : depending on intonation can be a legit "have i asked you to go grocery shopping?" to a challenging "why are you still here?(go buy stuff!)" 我叫你去买菜，没有吗？ - I asked you to go grocery shopping, did or didn't i ? 我叫你去买菜，没有吧~？ - I asked you to go grocery shopping, huh......nah i didn't ! (dismissive) 我叫你去买菜，有没有？- a proper version of example #2, again depending on context and intonation. But will usually be a legit question of "have i asked you yet ?" Hope that clears up what you need to know !

usage of '没有' 1.means "no", don't have somthing. for example: A:你有没有手机 B: 没有 2.means'haven't done sth'. for example: A: 你作业完成了没有 B: 没有 when 没有used in a interrogative sentences, generally ask you"did you finish sth",'have you done sth'

There are some little mistakes. 1.The word has the meaning of "understand" should be "懂" instead of "董".（The latter is the first name of a person. And my first name is 董.^ ^) 2." A:我叫你，你怎么回答？"------------Based on the context, I think the sentence should be" A:我叫你，你怎么（没有）回答？". 3.B:对不起，我正听录音呢，没有（开）。--------------I'm kind of puzzled about“没有（开）”here. I think it should be "没有（听见/听到）",but it seems that you don't have the option like "听见/听到". 4.A: 老师，这些练习题我做（对）了没有？ B: 你没都做（完),（对）了三道题，做错了道题。-------------------The answer should be consistent with the question. So it should be"你没都做（对）" instead of "你没都做（完）" 5. 快开（上）窗户吧，屋子里太热了。--------------------“开上窗户” sounds sort of odd but it seems that no better choice. 6. A:我给你的书你看（完）了没有？ B:还没有看（开）呢。---------------------The answer should be based on the question and the question used phrase "看完", so the answer should also use " 看（完）". ----------------------------------------------------------------------------------------------- So I summarized all of these homework as followed: o(∩_∩)o 1. 这课的语法你听（懂）了没有？ 2. A:我叫你，你怎么（没有）回答？ B:对不起，我正听录音呢，没有（听见/听到）。 3. A: 你看（见）麦克了没有？ B: 看（见）了，他正在操场跑步呢。 4 A: 老师，这些练习题我做（对）了没有？ B: 你没都做（对）,（对）了三道题，做错了道题。 5 快（开）窗户吧，屋子里太热了。 6 A:我给你的书你看（完）了没有？ B:还没有看（完）呢。 7 这课课文有点儿难。我没有看（懂）。

The words are: 懂，完，见，对，上，and 开. I will put my answers after each in brackets ie (开）. 1. 这课的语法你听（懂）了没有？ 2. A:我叫你，你怎么回答？ B:对不起，我正听录音呢，没有（开）。 3. A: 你看（见）麦克了没有？ B: 看（见）了，他正在操场跑步呢。 4 A: 老师，这些练习题我做（对）了没有？ B: 你没都做（完),（对）了三道题，做错了道题。 5 快开（开）窗户吧，屋子里太热了。 6 A:我给你的书你看（完）了没有？ B:还没有看（完）呢。 7 这课课文有点儿难。我没有看（懂）。
