对不对对不对

Answer 1

一、同义句转换
前两题正确：should do sth = be supposed to do sth，意思是“应该/应当做某事”。
但是后两题不对，be supposed to do sth没有be allowed to do sth或can do sth的意思。
可以分别改成：
3. are forbidden to
4. aren't allowed/permitted to 或 are forbidden to 或 mustn't

二、翻译句子
1. first time有误，应该改成：for the first time
2. 正确
3. 错误，主语搞笑了，呵呵（介词短语不能做句子主语），可以写成：
Playing football isn't allowed in the classroom.
4. an hour ago不对，ago一般只用于一般过去时。可以改成：
They are supposed to arrive/get/reach here an hour ahead/earlier.
或：They are supposed to have arrived here an hour ahead/earlier.

Answer 2

1 What are you supposed to say when meeting someone in the first time?
2 I was supposed to arrive at 7 that day.
3 No playing football in the classroom.
4 They were supposed to arrive an hour before.
第一句问题不大,后面几句就比较严重的中国英语了
