Dear teachers,

Would you be kind enough to tell me whether I am right with my attempt to paraphrase the following sentences?

1.1. The lecture is supposed to begin at eight.
1.2. The lecture is to begin at eight.

2.1. I expect her to come and help.
2.2. She is to come and help.

3.1. It was planned that we should wait for them in the camp.
3.2. We were to wait for them in the camp.

4.1. It was arranged that he should meet her at the station.
4.2. He was to meet her at the station.

5.1. It is necessary that you should do it.
5.2. You must do it.

Thank you for your efforts.

Regards,

V.

Gabber's suggestions are all fine, but all of your paraphrasings are grammatically correct.
