Answer 1

1.介词填空
( what )( about )going cycling?
2.适当形式填空
How about ( having )(have)a cup of tea?--介词about后用ing形式
The ( entrance )(enter)of the hall is not very big. enter的名词形式
There are ( thirty )(thirty)floors in this building.I live on the( twentieth )(twenty)floor.--第一空用基数词，这栋楼有30层，第二空用序数词，我住在第二十层
I wrote many ( invitations )(invite)yesterday. 我昨天写了很多邀请卡。用名词形式
3.改错
How about go cycling. go 改成going 介词后用动词ing
4句型转换
①Many people use old things again.(同义句）
Many people( reuse )old things.
②The teather became angry.(同义句）
The teather( is )angry.
③Let's go home on foot.(同义句）
（shall )( we )( go )home on foot?
④Most students do their homework st school.〔st school划线〕（划线提问）
(where )( do )most students( do )their homework?
⑤This coat cost me 500 yuan.〔500 yuan划线〕（划线提问）
( How )( much )( does )this coat cost you?
( How )( much )( is )this coat?(同义句）

Answer 2

②The teather became angry.(同义句）
The teather( is )angry.
became是过去式，同义句也应该是过去式吧
