1. I went to Paris two days ago. I had already been to Europe several years before.
2. We ate Chinese food for dinner last night, that my mother had bought in the supermarket. (I think the sentence should be changed here)
3.She is very tired; she went to bed late last night.
4. Her bus was late. When she arrived at school, the lesson had started.
5. When we arrived home, the door was open. Someone had broken through it!
6. When she came back home, the kitchen was spotless. Her daughter had cleaned it.
7. Last Sunday,we did our homework then we went to the cinema.

Is it right ??

Well done ,Abderrahmane! You're right;the second sentence is a bit awkward and needs to be restructed. can you make better constructed and less awkward?

Is it now right ??

2) We ate Chinese food for dinner which my mother had bought in the supermarket last night.

OK! But did mother buy the food last night or did you eat it last night ?(word order )

Hhhhh Yup! I thought it would be better to place it at the end but it ruined everything!

2) We ate Chinese food for dinner last night, which my mother had bought in the supermarket.

What about now ?
Thanks Mrs.

never mind! you were doing quite well , but it still needs to be reconsidered.What if it started with
"Last night,we ate ............." for the relative clause "which my mother had bought......." to get a bit closer to its referent "chinese food"?

Yup That's perfect now ! That way, the relative clause will directly modify the object !! Thank You Mrs. !
