Hello,teachers!

Which one is correct?

1 I don't think it will rain tomorrow____?

A don't you B do you C won't it D will it

2 I think two days_____enough to finish this task.
A is B are

I think right answer should be B. But I have read a sentence: one thousand kilometers is a long journey. So I got confused.

3 Which sentence is correct?
1 80% students are doing homework.
2 80% of students are doing homework.

Thank you!

1. I don't think it will rain tomorrow, will it? (do you could be possible as well.)
2. I think two days are enough to finish this task. - just a guess
3. 80% of students are doing homework. - just a guess

Please keep in mind that I'm not fully sure if #2 and #3 are correct.
However, I'm sure #1 is correct.

Anyway, thanks for the interesting questions.
I also want to know our teachers' and other members' opinions

Cheers!

For the third sentence, I assumed that we are talking about some certain students not students in general.

PS: I'm not sure a hundred percent for the first sentence, though.

Although Nightmare85 pointed out 'will it' for the first one I think the technical expected answer is 'do you' (taq question). I understand 'will it' could be used but something tells me the test writer expects the students to mark 'do you'.

And regarding the last one I would say 80% of the students are doing their homework.

B is the correct answer. The sentence starts with what one person thinks about the chances of rain and ends with asking another person what they think of the chances of rain. The first person is asking another person for agreement.
I reckon the standard sentence is 'I don't think it will rain tomorrow, do you?', that is the only one which came to my mind at first.

However, when I read Nightmare85's answer I realized that 'I don't think it will rain tomorrow, will it?' may also be possible, although less likely. Above you gave one interpretation, namely, the first person is asking another one for agreement, but is it the only possible interpretation? What if the speaker is just wondering whether it will rain the next day, just talking to himself?

But if you finish a sentence with "do you" when talking to yourself it sounds a bit weird, doesn't it?

The person may start with an initial guess that it is not likely to rain and then immediately change her mind and ask herself: will it?

So you agree that "will it" is a possible answer in this case ...

It may be weird but not uncommon when you are trying to learn a foreign language.
I often talk to myself when I am trying to learn a foreign language.

(Sorry, I know it is off the topic and not related to the original questions but I couldn't resist.)

1- when we have a question tag and the first verb is in sentence is in a negative form the second verb will be in afirmative, in this case we are asking about opinion. so the right answer is B

2- B ; are always with plural.

3- B wih students

***** NOT A TEACHER *****

Hello, Harry.

(1) You are correct: a question like No. 2 is very confusing.

(2) Teachers should not have this kind of question on a test.

(3) As you said, many books prefer the singular.

(a) Many books say that if you are talking about the "WHOLE

AMOUNT," it is better to use the singular.

Examples from Longman English Grammar:

Three weeks is a long time to wait.
Two hundred pounds is a lot to spend.
Forty miles is a long way.

Examples from The Grammar Book:

1,000 miles is a long distance.
2 million dollars is a lot of money.
5 years is a long time to spend on a thesis.

(4)

I do not think that it would be fair to mark your answer as "wrong"

if you chose "is." You could explain to your teacher (very respectfully,

of course) that you were thinking of "two days" as a unit:

An amount (singular) of 2 days IS enough to finish this task.

(5) Some teachers feel that "two days are" is only correct if you are

thinking of the "two days" as individual days -- not as a unit. Maybe

something like :

Those two days were completely different from each other.

***** Thank you *****
