1．Many students have dropped out of school and now the number of our class has ________50.
A．reduced by
B．reduced toC．increased to
D．increased by
解析：選B。reduce...to后面數(shù)字指減少后的總量，reduce...by后面數(shù)字指純減少的量或比率。由上面說到drop，故排除C、D。
【即境活用】
2. Since then the number of people stopping smoking ________10%.
A．has reduced to
B．reduces byC．has reduced by
D．reduces to
解析：選C。由since then可判斷主句應(yīng)用現(xiàn)在完成時，排除B、D兩項；再根據(jù)句意“自從那時戒煙人數(shù)減少了10%”，強調(diào)差額用介語by，故選C。
② likely adj. 很可能的，看來要發(fā)生的；(像是)可靠的，可信的；似乎有理的
adv. 很可能
(回歸課本P9) Drug users are more likely to get into trouble at school.
吸毒者更有可能在學(xué)校遇到麻煩。
【歸納總結(jié)】
①

＝He is likely to be late.他可能會遲到。
②“He said you’d be giving them a lift.” “Not likely！”
“他說你會讓他們搭便車。”“絕不可能！”

如果繼續(xù)吸煙，你很可能會健康狀況不佳。
④That means the price is likely to go down because of the competition.這意味著價格有可能因為競爭而下降。
【例句探源】
likely，possible，probable
三者都有“可能的”之意，區(qū)別如下：
(1)likely是形容詞，表示某事很可能發(fā)生，與probable 意思相近，但主語可以是人也可以是物。常用于“It is likely that...或sb./sth.be likely to do...”句型中，但不能說“It is likely for sb.to do sth.”。
(2)possible可能性相對小，作表語時，主語不能是人，常用句式為“It is possible for sb. to do sth.”或“It is possible that...”。
【易混辨析】
(3)probable 帶有“很可能”的意味，語氣比possible強，作表語時不能用人或不定式作主語，常用句式為“It is probable that...”。
①It isn’t
likely that I should accept such an offer as that.
②It’s possible_to break with old habits.
③It is _probable that he will succeed.
3.Young Americans who don’t go to university ________get jobs which bring low income.
A．a(chǎn)re likely toB．a(chǎn)re possible to
C．were able to
D．liked to
解析：選A。句意是：沒有上大學(xué)的美國年輕人可能做一些低收入的工作。likely可用于sb./sth.is likely to do而possible不能。
【即境活用】
4．(山東青島質(zhì)檢)A senior firefighter said it was__________that the fire，which broke out at midnight，was caused by someone on purpose.
A．possibly
B．likely
C．probably
D．obviously
解析：選B。根據(jù)It is likely that……句型得出答案，其它三個詞都是副詞，不能用于該句型。
③ affect vt. 影響，對……有壞影響；(疾病)侵襲；假裝；喜歡
(回歸課本P9) Smoking in a park doesn’t
affect other people in the same way.
在公園吸煙不會以同樣的方式影響別人。
【歸納總結(jié)】
【例句探源】
①Peter Taylor finds out how computers and the Internet are going to
affect our lives.
彼得·泰勒試圖弄清計算機和互聯(lián)網(wǎng)將如何影響我們的生活。
②(牛津P31)They were deeply affected by the news of her death.

③(高考遼寧卷)The experiment showed that our body clocks are affected by light and temperature.
這項實驗表明我們的生物鐘受光線和溫度的影響。
④She was affected with high fever.
她發(fā)高燒。
affect，effect，influence
三個詞都有“影響”的意思。
(1)affect指“產(chǎn)生的影響之大足以引起反應(yīng)”，著重“影響”的動作，有時含有“對……產(chǎn)生不利影響”的意思。
(2)effect作“影響”講時，通常用作名詞，構(gòu)成have an effect on“對……有影響”。effect作動詞時，指“使(某事物)產(chǎn)生；使發(fā)生；引起”，著重“造成”一種特殊的效果。
(3)influence指“通過說服、舉例等對行動、思想、性格等產(chǎn)生不易覺察到的、潛移默化的影響”。
【易混辨析】
①The games don’t have a(n) _effect on grownups but affect students a great deal.
②Influenced by a high school biology teacher，he took up the study of medicine.
③This book effected a change in my opinion.
5．Critics believe that the control of television by mass advertising has ________the quality of the programs.
A．lessened
B．declined
C．a(chǎn)ffected
D．effected
解析：選C。句意為：批評家認(rèn)為電視被大量的廣告所控制，這影響了節(jié)目的質(zhì)量。affect常指不好的影響；lessen“減少”；decline“降低”，指力量、權(quán)力、數(shù)量等的削減；effect“引起；產(chǎn)生”，只有affect符合句意。
【即境活用】
④ recognise vt. 辨認(rèn)出；認(rèn)出；認(rèn)識到；認(rèn)知
(回歸課本P19)Participants learn to recognise smoking triggers...

【例句探源】
recognise，know
(1)recognise 指把原來認(rèn)識的人/物再次“辨認(rèn)出”，是非延續(xù)性動詞。
(2)know“認(rèn)識并熟悉某人/物”，是延續(xù)性動詞。
①Sometimes we can’t recognise,_one’s voice on the phone even though we know him/her.

【易混辨析】

A．to recognizeB．recognizing
C．recognize
D．recognized
解析：選D。句意：Alexander試圖使自己的工作在醫(yī)學(xué)界得到認(rèn)可。本題考查非謂語動詞作賓補。get sth.done表示使某事物被做，如get my hair cut表示理發(fā)；get her finger burnt表示她的手指被燒傷。
【即境活用】

A．didn’t recognize
B．hadn’t recognized
C．haven’t recognized

【例句探源】
break into，break in
兩者都有“闖入”之意。break into中，into是介詞，后需接賓語；break in 是不及物動詞短語，其中in是副詞，不接賓語。另外，break into還有“突然……起來”之意，相當(dāng)于burst into；break in還可以表示“插嘴”等。
①We had to break_into the house as we had lost the key.
②Never break_in while others are talking.
【易混辨析】

A．break up
B．break out
C．break through
D．break in
解析：選C。句意為：科學(xué)家們希望能盡快在應(yīng)對甲型H1N1流感病毒方面有所突破。break up“分解，打破”；break out“發(fā)生，爆發(fā)”；break through“突破”；break in“闖入，打斷(談話)”，據(jù)句意可知答案為C。
⑥ give up 放棄；交出，讓出；認(rèn)輸

B．in
C．up
D．a(chǎn)way
解析：選C。give out“用完，用盡”；give in“讓步，投降”；give up“放棄，不抱希望”；give away“泄露，分發(fā)”。由句意可知，此處指“對她不抱任何希望”，故答案為C。
【即境活用】
11.He pretended to be a German，but his Swedish accent gave himself________.
A．a(chǎn)way
B．up
C．off
D．out
解析：選A。考查give的固定短語。句意：他假裝是德國人，但他的瑞典口音使他暴露了。“暴露”應(yīng)用give away。give up指“放棄”；give off 指“放出，發(fā)出”；give out指“發(fā)出，分發(fā)”。
句型梳理
①【教材原句】 Now I work in a centre for drug addicts，helping others to stop taking drugs.(P13)
現(xiàn)在，我在一個戒毒中心工作，幫助其他吸毒者戒毒。
【句法分析】 本句中的helping others to stop taking drugs是v.ing形式在句子中作狀語，表示方式或伴隨情況。
①The little girl stood there，crying for milk.
這個小女孩站在那兒，哭著要牛奶喝。
②He worked late into the night，preparing an important report.
他工作到深夜，在準(zhǔn)備一個重要的報告。

12.(高考四川卷)The lawyer listened with full attention，________to miss any point.
A．not tryingB．trying not
C．to try not
D．not to try
解析：選B。句意：這名律師全神貫注地聽，盡力不錯過任何要點。本題考查非謂語動詞作伴隨狀語。不定式作狀語時和前面的部分如用逗號隔開，表示意想不到的或事與愿違的結(jié)果，不定式前通常加only或never，所以動詞不定式在結(jié)構(gòu)和題意上都不符合本題的要求，D項被排除；A、C兩項結(jié)構(gòu)錯誤，也被排除。
【即境活用】
13．(高考重慶卷) The news shocked the public，________to great concern about students’ safety at school.
A．having ledB．led
C．leading
D．to lead
解析：選C。句意：這條資訊使廣大民眾感到很震驚，引起了人們對在校學(xué)生安全的擔(dān)憂。考查非謂語動詞作結(jié)果狀語。首先排除B和D兩項； having done指動作先于謂語動詞發(fā)生，在此不符合語境，故只能選擇C。
② 【教材原句】 Whatever you’re doing when you want to smoke—do something else！(P19)
無論你在做什么，當(dāng)你想抽煙時，做點別的事吧！
【句法分析】 考查whatever的用法。(1)引導(dǎo)讓步狀語從句，在從句中作主語或賓語，其含義相當(dāng)于no matter what，意為“無論，不管”，其位置可在主句前，也可在主句后。
