Thank you veru much.

Question

I have a few more doubts.
1) While my family went out, I called a friend. (I think went out is wrong)
2) They expect the weather will be warm
They expect the weather to be warm
3) They raise money for (not to) a charity.

Can "while" be followed by the simple past in this case?

Answer 1

1) While my family went out, I called a friend. (I think went out is wrong)
I'd say, "While my family was out, I called a friend." (Or "While my family was gone, I called a friend.")

2) They expect the weather will be warm
They expect the weather to be warm
The second sentence is better, but you'll need to put a period at the end.

3) They raise money for (not to) a charity.
Using "for" is correct; "to" is not correct.
