【重要語(yǔ)法】
現在完成時(shí)常與下列表不明確的狀語(yǔ)連用
1．a(chǎn)lready 和 yet
already “已經(jīng)”（多用于肯定陳述句）。
如：He has already gone home. 他已經(jīng)回家了。
yet “已經(jīng); 還”（用于否定句或疑問(wèn)句）。
如：Have you found him yet? 你已經(jīng)找到他了嗎？

※ already 也可用于疑問(wèn)句，表“出乎意料或驚奇”

2．ever 和 never
ever “曾經(jīng)”（多用于疑問(wèn)句，問(wèn)初次經(jīng)歷）。
如：I have ever been abroad. 我曾出過(guò)國。
never“從未；從來(lái)不”（多用于否定陳述句），常回答ever的句型。

二、要點(diǎn)講評
1.---- I really hate to go shopping. 我真討厭去購物。
---- So do I . 我也是。
So do I .為倒裝句，表示前面提到的肯定情況也同樣適合另外一個(gè)主體，表“某某也一樣”，結構為“so + be /情態(tài)動(dòng)詞/ 助動(dòng)詞 + 主語(yǔ)”。
如：Jim is a student, so is Tom. 吉姆是一名學(xué)生，湯姆也是。
Jim can swim, so can Tom. 吉姆會(huì )游泳，湯姆也會(huì )。
Jim likes sports, so does Tom. 吉姆喜歡運動(dòng)，湯姆也喜歡。
如表前面不怎樣，后面“也不”怎樣時(shí)，其結構為“ neither/ nor + be /情態(tài)動(dòng)詞/ 助動(dòng)詞 + 主語(yǔ)”。
如：Jim wasn’t Chinese, neither/ nor were they. 吉姆不中國人，他們也不是。
Jim can’t speak Japanese, neither can I . 吉姆不會(huì )說(shuō)日語(yǔ)，我也不會(huì )。
Jim didn’t go there, neither did I . 吉姆沒(méi)去那兒，我也沒(méi)去。
如前后兩句表達的是同一個(gè)主體，則不能倒裝，表“的確如此”。
如：Jim is a good student. So he is. 吉姆是一名好學(xué)生，的確如此。
Jim swims well. So he does. 吉姆游泳很好，的確如此。
2.At that time, China was the country with the largest population in the world.
那時(shí)，中國是世界上人口最多的國家。
population為不可數名詞，表示人口的多少只能用 “l(fā)arge”或 “small”修飾，提問(wèn)人口用“what”.
如：The population of Shanghai is larger than that of Beijing. 上海的人口比北京多。
What’s the population of China?= How many people are there in China?
中國的人口有多少？
3. Great changes have taken place in China. 中國發(fā)生了巨大變化。
take place 指必然性的“發(fā)生”或有計劃、安排之內的“舉行”。
如：The meeting will take place next Friday. 會(huì )議將在下周五舉行。
happen 指偶然的、沒(méi)有預料的“發(fā)生“，其結果往往給人帶來(lái)不幸或麻煩。
如：The accident happened yesterday. 事故發(fā)生在昨天。
※兩者都不用于被動(dòng)語(yǔ)態(tài)。
如：The population has increased a lot. 人口增長(cháng)發(fā)很多。
4.increase 可作及物動(dòng)詞也可作不及物動(dòng)詞。其含義是“增長(cháng)，增加，加強”等。
increase by… 指“增加了……”; increase to…指 “增加到……”
5. and about one fifth of the people in the world live in China.
而且世界上大約五分之一的人口生活在中國。
one fifth 是分數表達法。英文分數表達法：分子為基數詞，分母為序數詞，先讀分子后讀分母。當分子大于1時(shí)，分母的序數詞則變?yōu)閺蛿担苯釉谠~尾加“s”。
如：one fourth四分之一three fourths 四分之三one second二分之一two thirds三分之二
6.It has worked well in controlling China’s population.
它在控制人口數量方面取得了顯著(zhù)的功效。
work well in doing sth. 表“在……方面很有功效”, 如:
如：Doing eye exercises works well in protecting our eyesight.
做眼保健操在保護視力方面很有功效。
7. Because of our large population, we are short of energy and water.
be short of… 表 “缺乏……”
如:She is always short of money at the end of every month. 每個(gè)月底她總是缺錢(qián)。

如:TV is short for television. TV是television的縮寫(xiě)形式.
8. Can all Chinese families offer their children a good education?
所有的中國家庭都能給他們的的孩子提供良好的教育嗎？
offer 表“（主動(dòng)）給予， 提供”
offer sb. sth. “提供某人某物”.
如：I offered him a glass of wine. 我敬了他一杯酒。
offer to do sth. “（主動(dòng)）提出做某事”
如：She offered to cook for her mother. 她提出幫她媽媽煮飯。
I can’t go shopping in big stores unless I travel for a couple of hours.
我得花幾個(gè)小時(shí)，才能到大的商場(chǎng)購物。
9. unless = if not 表“除非…; 如果不”，引導條件狀語(yǔ)從句。
如：I won’t go unless I hear from you. = I won’t go if I don’t hear from you.
如果你不通知我，我就不去。
Unless Bill studies hard, he’ll fail in the exam. 如果比爾不努力, 他不會(huì )通過(guò)考試的.
10. a couple of… 表 “幾個(gè)人或幾件事”.
如:a couple of years ago 幾年前; a couple of students 幾個(gè)學(xué)生
couple 指任何兩件同類(lèi)的東西
如: a couple of watches 兩只手表； five couples of cats 五對貓
11.pair 指兩件不可分開(kāi)使用的東西,它們可指兩件互不相連的東西(鞋子、襪子等)，也可指
兩部分構成的一件東西（褲子、剪刀等）。
如：a pair of shoes 一雙鞋子a pair of pants 一條褲子
三、典型例解
( )1.-They have been to Australia.
-So _____ I.
A. do B. have been C. did D. have
分析：D 此句為so引導的完全倒裝句。其含義為“A如此，B也如此。”其結構是so+be/助動(dòng)詞/情態(tài)動(dòng)詞+主語(yǔ)。本句為完成時(shí)態(tài)，其助動(dòng)詞是have。故選D。
( )2.The population of Shanghai is larger than _____ of Shenyang.
A. that B .it C. one D. this
分析：A 此句要用相同成分即上海的人口和沈陽(yáng)的人口做比較。因為population是不可數名詞，所以用that代替。如果是復數名詞則要用those來(lái)代替。
( )3.-_____ the population of the U.S.A. in 2005?
-It _____ about 296 million.
A. What is; is B. What was; was
C. How many is; was D. How many was; is
分析：B 問(wèn)人口的多少用what而不用how many。本題問(wèn)的是2005年的人口， 故為過(guò)去時(shí)態(tài)。
( )4._____ of the teachers are women in our school.
A. Two third B. Two threes C. Two thirds D. Second three
分析：C分數的表達法是基數詞在前表示分子，序數詞在后表示分母；當分子大于1時(shí)，表示分母的序數詞要加s。
( )5.He’s read this book before, _____?
A. hasn’t he B. doesn’t he C .isn’t he D. wasn’t he
分析：A 本題考查反義疑問(wèn)句反問(wèn)部分的時(shí)態(tài)與人稱(chēng)的單復數要與陳述部分一致的用法。
( )6.The _____ population may be the greatest challenge of the world today.
A. increase B. increased C. increasing D. increases
分析：C 本題考查increase的現在分詞作定語(yǔ)的情況，表示“正在增長(cháng)的”。increased是它的過(guò)去分詞也可作定語(yǔ)，但表示的是“已增長(cháng)過(guò)的”。
( )7.The little girl has _____ finished reading the book you lent her.
A .already B. yet C. still D. once
分析：A already“已經(jīng)”，常用覨t now.
分析：C 上句為否定情況，應用neither/nor+助動(dòng)詞+主語(yǔ)，表示“我也未參觀(guān)過(guò)造紙廠(chǎng)”。

( )9.Students today have a lot of pressure(壓力) _____ they have to learn too much knowledge at school.
A. in order to B .unless C. because D .because of
分析：C in order to和because of后面不能接從句，unless不符合題意。故選C，用because。
( )10.-I have never visited a paper factory.
-_____
A. So have I. B. So I have. C. Neither have I. D.I haven’t now.
