1.　�？嫉膸追N倒裝結(jié)構(gòu)

　　1) 當(dāng)表示否定或基本否定的詞或詞組位于句首作狀語時(shí)用倒裝。這類詞或詞組常用的有：never, nowhere, seldom, rarely, little, hardly, scarcely, barely, not until, not only, by no means, in no time, under no circumstances, under no condition, in no way, in no case, at no time, on no account等。

　　Never have I heard it before.

　　Nowhere can I find my lost watch.

　　Under no circumstance should a student cheat in the exam.

　　Not only was Churchill a statesman, but also a poet.

　　Note: 當(dāng) “no sooner … than”和“hardly/scarcely … when/before”位于句首時(shí)用倒裝。該結(jié)構(gòu)表示“一…就…”，在時(shí)態(tài)上主句一般用過去完成時(shí)，when或than引導(dǎo)的從句用一般過去時(shí)。

　　Hardly/Scarcely had I got home when/before the bell rang.

　　No sooner had the performance begun than the lights went out.

　　2) 當(dāng)here, there, then, thus, only, hence, little等副詞位于句首，句中主、謂用倒裝。

　　Here is the book for you.

　　There goes the bell.

　　Then came the order to take off.

　　Thus arose the division between the developed and developing countries.

　　3) 當(dāng) “so/such … that”結(jié)構(gòu)中的so或such 位于句首時(shí)用倒裝。

　　So cold was it at night that I could hardly fall asleep.

　　Such was the force of explosion that all the windows were broken.

　　4) 分句以so, neither, nor, no more等副詞位于句首，表明前面句子中所說明的情況也使用于后面的句子時(shí)用倒裝。

　　Copper is a good conductor. So are many other metals.

　　He didn’t see the film last night, neither did she.

　　2. 強(qiáng)調(diào)句型

　　這里講的強(qiáng)調(diào)句主要是以it為引導(dǎo)詞的分裂句。其構(gòu)成形式為：It is (was) +被強(qiáng)調(diào)部分+ that(who, which) + 句子的其他部分。被強(qiáng)調(diào)的部分通常為主語、賓語和狀語。

　　It is only when one is ill that one realizes the value of health.

　　It is what you will do that is essential.

　　Note:

　　在被強(qiáng)調(diào)部分的后面，一般用that引出句子的其他部分。但是如果強(qiáng)調(diào)的部分是表示人的名詞，那么也可用who;如果是指物的名詞也可用which。

　　It was Jane that/who lent me the money.

　　It was this novel that/which they talked about last night.

　　如果強(qiáng)調(diào)的是原因狀語從句，只能用because引導(dǎo)，不能由since, as或why引導(dǎo)。

　　It was because(不用since或as) he had never had the opportunity that John hadn’t learned to drive.

　　有三類句子成分不可以進(jìn)行強(qiáng)調(diào)，即表語、謂語動(dòng)詞和由though, although,　whereas等引導(dǎo)的從句。

　　It is although he is young that he can speak four languages. (誤)

　　Although he is young, he can speak four languages. (正)

　　It is whereas he prefers pop song that I like classical music. (誤)

　　I like classical music whereas he prefers pop songs. (正)

　　3. 使役動(dòng)詞后的賓語補(bǔ)足語

　　使役動(dòng)詞除了要有賓語之外還要加上賓語補(bǔ)足語才能使句子的意義完整。常用的使役動(dòng)詞有：have, want, make, get, leave, set, let等。可以擔(dān)當(dāng)使役動(dòng)詞賓語補(bǔ)足語的有名詞，形容詞，介詞短語，動(dòng)詞不定式和分詞等。

　　All work and no play makes Jack a dull boy.

　　A good night’s rest will set you right.

　　Note:

　　動(dòng)詞不定式可以擔(dān)當(dāng)使役動(dòng)詞的賓語補(bǔ)足語，但在make, let, have等使役動(dòng)詞后，動(dòng)詞不定式作賓語補(bǔ)足語時(shí)不用to。

　　He made her give up the opportunity.

　　What would you have me do?

　　Her pride would not let her do this.

　　分詞也可以擔(dān)當(dāng)使役動(dòng)詞的賓語補(bǔ)足語�，F(xiàn)在分詞表示正在進(jìn)行的主動(dòng)意義，而過去分詞表示已經(jīng)完成的被動(dòng)意義。

　　Her remark left me wondering what he was driving at.

　　The joke set them all laughing.

　　He managed to get the job done on time.

　　I’ve just had some new photos taken.

　　4. 平行結(jié)構(gòu)

　　在英語中，當(dāng)兩個(gè)或兩個(gè)以上的同等成分(主語，謂語，賓語，表語，定語，狀語，賓語補(bǔ)足語等)并列時(shí)，要求它們的詞性或結(jié)構(gòu)相同，即名詞對名詞，介詞短語對介詞短語，分詞對分詞，句子對句子等等。這就是英語的平行結(jié)構(gòu)準(zhǔn)則。一般在使用并列連詞如and, but, or, neither … nor, either … or, not only .. but also, both … and, more(less) … than, as well as，rather… than等時(shí)，要注意不要違反平行結(jié)構(gòu)準(zhǔn)則。
