2运用反义词（组）的否定式进行转换
1. It’s clear that this visit is different from last time.
It’s clear that this visit is not the___ ___last time.
答案：same as
解析：be different from意为“与……不同”；the same as意为“与……相同”，其否定式与be different from同义。
2. I think wealth is less important than health.
I ___ think wealth is ___ important than health.
答案：为don’t，more
解析：less important的意思是“没有（不及）……重要”；more important的意思是“（比）……更重要”，该结构与not连用，则表示“不比……更重要”。
另外，有的反义词即使不与否定词连用，而只需改变句子结构也可构成同义句。如：
He lent some money to his friend.
He friend ___ some money ___ him.
答案为borrowed，from
解析：borrow…from...意为“向……借……”；lend…to...意为“把……借给……”。两个结构意思相反，但若变换“借出者”与“借入者”的位置，则可转换为同义句。
3运用不同语态进行转换
1. The manager left two hours ago.
The manager _____ ____ ____ for two hours.
答案：has been away
解析：leave为非延续性动词，不能与for two hours这样的一段时间连用，而改成be away这样的延续性动词后，则可连用一段时间。
2. The film began five minutes ago.
The film has been _____ _____ five minutes.
答案：on for
解析：has been提示时态是现在完成时态，“for 时间段”表示“持续（一段时间）”，常用在含有现在完成时态的句子里。
3. Mr Li joined the Party twenty years ago.
Mr Li _____ _____ _____ the Party for twenty years.
答案：has been in
解析：短暂动词join，意为“参加、加入（组织，政党）”，不能与延续时间状语连用，与延续性时间状语连用时，将join改成be in或be a member in…。
