9、rvoir last winter.去年冬天我們修建了一座水庫。(已經(jīng)建成)倒裝倒裝句之全部倒裝全部倒裝是只將句子中的謂語動詞全部置于主語之前。此結(jié)構(gòu)通常只用與一般現(xiàn)在時和一般過去時。常見的結(jié)構(gòu)有：1) here, there, now, then, thus等副詞置于句首, 謂語動詞常用be, come, go, lie, run。There goes the bell.Then came the chairman.Here is your letter.2) 表示運動方向的副詞或地點狀語置于句首，謂語表示運動的動詞。Out rushed a missile from under the b

12、ime_ in the meeting-roomA. is smoking permittedB.smoking is permittedC. smoking is it permittedD.does smoking permit答案A. 這是一個倒裝問題。當否定詞語置于句首以表示強調(diào)時，其句中的主謂須用倒裝結(jié)構(gòu)。 這些否定詞包括no, little, hardly, seldom, never, not only, not until等。本題的正常語序是 Smoking is permitted in the meeting-room at no time.2) Not until the

13、 early years of the 19th century _ what heat is.A. man did know B. man know C. didnt man know D. did man know答案D. 看到Not until的句型，我們知道為一倒裝句，答案在C，D 中選一個。改寫為正常語序為，Man did not know what heat is until the early years of the 19th. 現(xiàn)在將not提前，后面就不能再用否定了,否則意思就變了。以否定詞開頭作部分倒裝如 Not onlybut also, Hardly/Scarcelyw

I dont care also答案：B. nor為增補意思也不關(guān)心，因此句子應(yīng)倒裝。A錯在用 dont

17、 再次否定， C neither 用法不對且缺乏連詞。 D缺乏連詞。注意： 當so引出的句子用以對上文內(nèi)容加以證實或肯定時，不可用倒裝結(jié)構(gòu)。意為的確如此。Tom asked me to go to play football and so I did.-Its raining hard.-So it is.only在句首要倒裝的情況Only in this way, can you learn English well.Only after being asked three times did he come to the meeting.如果句子為主從復合句，則主句倒裝，從句不倒裝Only

21、ont I care B. nor do I careC. I dont care neitherD. I dont care also解析：答案為B.句中的nor引出部分倒裝結(jié)構(gòu)，表示也不。由 so, neither, nor引導的倒裝句，表示前一情況的重復出現(xiàn)。其中, so用于肯定句, 而 neither, nor 用在否定句中。并列結(jié)構(gòu)作主語時謂語用復數(shù)Reading and writing are very important.注意： 當主語由and連結(jié)時，如果它表示一個單一的概念，即指同一人或同一物時，謂語動詞用單數(shù)，and 此時連接的兩個詞前只有一個冠詞。The iron and

22、steel industry is very important to our life.典型例題The League secretary and monitor _ asked to make a speech at the meeting.A. isB. was C. are D. were答案B. 注： 先從時態(tài)上考慮。這是過去發(fā)生的事情應(yīng)用過去時，先排除A.，C.。本題易誤選D，因為The League secretary and monitor 好象是兩個人，但仔細辨別， monitor 前沒有the，在英語中，當一人兼數(shù)職時只在第一個職務(wù)前加定冠詞。后面的職務(wù)用and 相連。這樣本

23、題主語為一個人，所以應(yīng)選B。介詞小學英語介詞at，in與on在時間方面的用法at表示時間的一點;in表示一個時期;on表示特殊日子。如：He goes to school at seven oclock in the morning. 他早晨七點上學。Can you finish the work in two days. 你能在兩天內(nèi)完成這個工作嗎?Linda was born on the second of May. 琳達五月二日出生。1. at后常接幾點幾分，天明，中午，日出，日落，開始等。如：at five oclock (五點)，at down (黎明)，at daybreak (

Lets 包括說話者Lets have another try，shall we / shant we?= Shall we have another try?b.Let us 不包括說話者Let us have another try，will you / wont you?= Will you please let us have another try?否定結(jié)構(gòu)：Lets not talk of that matter.Let us not talk of that matter.感嘆句結(jié)構(gòu)感嘆句通常有what, how引導，表示贊美、驚嘆、喜 悅

28、、等感情。what修飾名詞，how 修飾形容詞，副詞或動詞，感嘆句結(jié)構(gòu)主要有以下幾種：掌握它的搭配，即掌握了感嘆句的重點。How +形容詞+ a +名詞+陳述語序How+形容詞或副詞+陳述語序What +名詞+陳述語序What+a+形容詞+名詞+陳述語序What+ 形容詞+復數(shù)名詞+ 陳述語序What+ 形容詞+不可數(shù)名詞+ 陳述語序How clever a boy he is!How lovely the baby is!What noise they are making!What a clever boy he is!What wonderful ideas (we have)!What

29、 cold weather it is!感嘆句的省略形式為：What a clever boy (he is)!典型例題1)_ food youve cooked!A. How a niceB. What a niceC. How nice D. What nice答案D. 由于How 修飾形容詞，副詞;what修飾名詞。且food為不可數(shù)名詞，因此A，B 排除。C How + adj. 后面不能再加名詞，因此只有D正確，其句型為What + adj. +n. (不可數(shù))2)_terrible weather weve been having these days!A. What B. Wha

30、t aC. How D. How a答案A. weather為不可數(shù)名詞，B，D排除。C為how + adj. 后面不應(yīng)有名詞。只有A，符合句型What +形容詞+不可數(shù)名詞。3) - _ I had!- You really suffered a lot.A. What a timeB. What time C. How a time D. how time答案A.感嘆句分兩類：1：What + n.+主謂部分2：How + adj. / adv. / v.+主謂部分。本題屬第一種，但省略了bad，相對于 What a bad time I had! 這是個習慣用語。強調(diào)句結(jié)構(gòu)?？嫉膹娬{(diào)句結(jié)

31、構(gòu)是it 引導的句子。It is (was) 被強調(diào)部分+ that (who) + 句子其他部分。此結(jié)構(gòu)強調(diào)的成分僅限于主語，賓語和狀語。It is from the sun that we get light and heat.It was not until I had read your letter that I understood the true state of affairs.典型例題1) It was last night _ I see the comet.A.the timeB.when C.thatD.which答案C. 強調(diào)句的結(jié)構(gòu)是： It +be +強調(diào)部分

(注意不用when)強調(diào)地點： It was in the lab that my father did the experiment yesterday evening.2)It is ten years _ Miss Green returned to Canada.A. thatB. when C. since D. as答案C. 考點是連詞用法。 本題易誤選為A. that. 其實本句不是強調(diào)句。若是，去掉It be that還應(yīng)是一個完整的句子。而本句去掉 It

34、isthat，只剩下ten years Miss Green returned to Canada. 不成句。因此本句不是強調(diào)句。It is /was +時間+ since其中is has been was had been.用助動詞進行強調(diào)強調(diào)句還有一種類型，就是用助動詞do (did，does) 強調(diào)謂語。She does like this horse.她的確喜歡這匹馬。Please do take care of yourself. 千萬保重。反意疑問句1)陳述部分的主語是I，疑問部分要用 arent I.Im as tall as your sister，arent I?2)陳述部分
