1.They went swimming last weekend.（改为一般疑问句）（）they（）swimming last weekend?2.The film isn't interesting at all.（改为同义句）The film is（）.3.I had a great time in Children's Park yesterday.（改为同义句）I （）（） in Chilren's Park yesterday.

1.did go
2.boring
3.was happy

1, did/ go
原句的谓语动词是went，所以可以得出改为一般疑问句时是助动词do而不是be动词is，再根据原句的事态和单复数可以知道是第三人称复数的过去式，所以是did，再将went变为原形go
2.boring
interesing 和boring 是反义词
3, had fun
have fun in doing sth = have a great time in doing sth.

1.did/go
2.boring(无聊的）
3.enjoy myself

Did they go swimming last weekend?
The film is boring.
I enjoyed myself in Children's Park yesterday.

这是正确答案，满意请采纳，谢谢！O(∩_∩)O
