高一英语同义句转换1、He is holding a book with the upper part under .

1.He is holding a book upside down.
我也不知道这个答案对不对.原句的意思应该是书拿反了吧.我只想到了upside down.
2、I am looking forward to receiving from you.
look forward to 是期望的意思,和expecting同意.由于原句中有from,这里可以猜到用收到信的另外一种说法：receive from sb.look forward to 中,to 是介词,后面接名词或动名词形式.

I am expecting your letter .
I am looking forward to hearing from you .
