母题二、 部分倒装
例：only then_________ how much damage had been caused. A. she realized B. she had realized C. had she realized D. did she realize
【解析】 D。only接副词位于句首时，全句要用部分倒装，又知道此时时态应用一般过去时。
_______, he talks a lot about his favorite singers after class. A. A quiet student as he may be B. Quiet student as he may be C. Be a quiet student as he may D. Quiet as he may be a student
母题三、only 短语置于句首引起的部分倒装
Only when I left my parents for Italy __ how much I loved them. A. I realized B. I had realized C. had I realized D. did I realize
【解析】句意：只有当我离开父母前往意大利，我才意识到我是多么的爱他们。Only引导的状语或状语从句位于句首时，主句需部分倒装。
【答案】D
母题四、as引出让步状语从句时，其结构为：形容词/副词/名词/动词+as (though)+主语+其它。
as引导让步状语从句时要倒装（形容词/ 副词/ 名词/ 动词 + as + 主语 + 谓语）。
e.g. Proud as they are, they are afraid to see me.
Child as he is, he seems to know everything.（child前不加冠词） Hard as he worded, he made little progress.
_______, his idea was accepted by all the people at the meeting. A. Strange as might it sound
B. As it might sound strange D. Strange as it might sound
C. As strange it might sound
【解析】句意：尽管这个观点听起来很奇怪，但他的观点被与会的所有人所接受。本题考查as引导的让步状语从句的倒装用法，这里的as 相当于though意思是“虽然、尽管”，从句中常使用倒装语序，常把表语成分提到as前面，但应注意被提前的名词前不用冠词. 【答案】D
母题五、倒装句中的动词时态
So involved with their computers that leaders at summer computer camps often have to force them to break for sports and games.
［A］ became the children
［B］ become the children ［D］ do the children become
