倒裝的六條原則：
1. so放在句首時(shí)表示承前肯定，這個(gè)句子用部分倒裝;
nor， neither放在句首時(shí)表示承前否定，句子也用部分倒裝;
2. 省略了引導(dǎo)詞if 的虛擬條件從句，可以把從句中的had， should， could， were中的任何一個(gè)提到從句最前面的位置，構(gòu)成部分倒裝;
3. as， though表示“盡管”時(shí)引導(dǎo)從句，從句中的表語可以置于引導(dǎo)詞之前構(gòu)成部分倒裝;
系動(dòng)詞后面的部分就是表語，形容詞、名詞、名詞性短語可以置于系動(dòng)詞之后。
例如：She is beautiful. They are students.
四級考試中出現(xiàn)的是由動(dòng)詞的過去分詞轉(zhuǎn)變的形容詞作表語的形式。
26. _B_ as it was at such a time， his work attracted much attention.
A Being published B Published C Publishing D To be published
當(dāng)題干是as引導(dǎo)一個(gè)從句，且as前為一個(gè)空格時(shí)他表示的就是盡管，空格處要填的就是表語。
being published 正在被出版; to be published 將要被出版。
此句恢復(fù)正常語序應(yīng)為： As it was published at such a time …
4. 表示否定含義的單詞或短語放在句首，句子用部分倒裝;
常見的一些表示否定含義的單詞：never， little， few， hardly (… when)， scarcely (… when) ;
seldom 難得，不常;nowhere 哪里都不。
常見的一些表示否定含義的短語：in no way 決不; on no account 決不;
under no circumstances 在任何情況下都不。
5. only + 狀語放在句首，句子用部分倒裝;(如果only去掉就是全部倒裝)
43. Only under special circumstances _C_ to take make-up tests.
A permitted are freshmen B freshmen are permitted
C are freshmen permitted D are permitted freshmen
freshmen 新生; make up for 彌補(bǔ)，補(bǔ)償; make-up tests 補(bǔ)考(緩考)。
6. 注意兩個(gè)表達(dá)形式：come what may 無論發(fā)生什么情況; say what you will 暢所欲言。
強(qiáng)調(diào)句式的補(bǔ)充內(nèi)容：被強(qiáng)調(diào)部分是疑問詞時(shí)的情況。
60. When I try to understand _C_ that prevents so many Americans from being as happy as one might expect， it seems to me that there are two causes.
A why it does B what it does C what it is D why it is
prevent sb. from doing sth. 妨礙(阻止)某人做某事。
強(qiáng)調(diào)部分本為： it is what that prevents so many …
又因?yàn)榫渲杏幸蓡栐~，應(yīng)寫為： what is it that prevents so 。..
但強(qiáng)調(diào)句式在句中作賓語成分，故正確寫法為： what it is that …
