Are these 3 statements correct?

Question

1) I'm looking for a good place to live (in)

Is the proposition IN correct in final position?

2) She got sad to hear that, so the only thing she needed was a friendly shoulder to cry on.

3) He wants a friend to spend the whole evening playing soccer with.

Thanks in advance ^^

Answer 1

Most English teachers will tell you that ending a sentence with a preposition is not proper grammar. I personally don't believe that, those sentences sound fine to me.

1) I'm looking for a good place to live. (Adding "in" sounds a bit redundant)

2) She was sad to hear that, and the only thing she needed then was a friendly shoulder to cry on.

3) He wants to spend the whole evening playing soccer with a friend.

Answer 2

1) I'm looking for a good place to live in. (Although some English teachers may complain about a preposition ending a sentence, 99% of people will say it like this.

2) After having heard this, she became sad, and the only thing she needed was a friendly shoulder to cry on.

3) He wants a friend who he can spend the whole evening playing soccer with.

Answer 3

Good place to live at

She became sad

whole evening to play soccer with

(or better still) wants a friend with whom he can spend the whole evening playing soccer
