【例句探源】

1.Many students have dropped out of school and now the number of our class has ________50.
A.reduced by    B.reduced to C.increased to D.increased by
解析:选B。reduce...to后面数字指减少后的总量,reduce...by后面数字指纯减少的量或比率。由上面说到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 by C.has reduced by D.reduces to
解析:选C。由since then可判断主句应用现在完成时,排除B、D两项;再根据句意“自从那时戒烟人数减少了10%”,强调差额用介语by,故选C。
② likely  adj. 很可能的,看来要发生的;(像是)可靠的,可信的;似乎有理的 
adv. 很可能
(回归课本P9) Drug users are more likely to get into trouble at school.
吸毒者更有可能在学校遇到麻烦。

③It is likely that you could suffer from bad health if you keep smoking.

④That means the price is likely to go down because of the competition.这意味着价格有可能因为竞争而下降。
【例句探源】
likely,possible,probable
三者都有“可能的”之意,区别如下:
(1)likely是形容词,表示某事很可能发生,与probable 意思相近,但主语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,但不能说“It is likely for sb.to do sth.”。
(2)possible可能性相对小,作表语时,主语不能是人,常用句式为“It is possible for sb. to do sth.”或“It is possible that...”。
【易混辨析】
(3)probable 带有“很可能”的意味,语气比possible强,作表语时不能用人或不定式作主语,常用句式为“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.are likely to     B.are possible to
C.were able to D.liked to
解析:选A。句意是:没有上大学的美国年轻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.(山东青岛质检)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:选B。根据It is likely that……句型得出答案,其它三个词都是副词,不能用于该句型。
③ affect  vt. 影响,对……有坏影响;(疾病)侵袭;假装;喜欢
(回归课本P9) Smoking in a park doesn’t affect other people in the same way.
在公园吸烟不会以同样的方式影响别人。
【归纳总结】
【例句探源】

④She was affected with high fever.

affect,effect,influence
三个词都有“影响”的意思。
(1)affect指“产生的影响之大足以引起反应”,着重“影响”的动作,有时含有“对……产生不利影响”的意思。
(2)effect作“影响”讲时,通常用作名词,构成have an effect on“对……有影响”。effect作动词时,指“使(某事物)产生;使发生;引起”,着重“造成”一种特殊的效果。
(3)influence指“通过说服、举例等对行动、思想、性格等产生不易觉察到的、潜移默化的影响”。
【易混辨析】
①The games don’t have a(n) _effect on grown?ups 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

解析:选C。句意为:批评家认为电视被大量的广告所控制,这影响了节目的质量。affect常指不好的影响;lessen“减少”;decline“降低”,指力量、权力、数量等的削减;effect“引起;产生”,只有affect符合句意。
【即境活用】
④ recognise  vt. 辨认出;认出;认识到;认知
(回归课本P19)Participants learn to recognise smoking triggers...

②He is recognised as the head of the company.
他被认为是公司的领导。
③It was recognised that he was not qualified for the work.

【例句探源】
recognise,know
(1)recognise 指把原来认识的人/物再次“辨认出”,是非延续性动词。
(2)know“认识并熟悉某人/物”,是延续性动词。
①Sometimes we can’t recognise,_one’s voice on the phone even though we know him/her.

A.to recognize      B.recognizing
C.recognize D.recognized

【例句探源】
break into,break in
两者都有“闯入”之意。break into中,into是介词,后需接宾语;break in 是不及物动词短语,其中in是副词,不接宾语。另外,break into还有“突然……起来”之意,相当于burst into;break in还可以表示“插嘴”等。

give away分发;放弃;泄露

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)
现在,我在一个戒毒中心工作,帮助其他吸毒者戒毒。
【句法分析】 本句中的helping others to stop taking drugs是v.?ing形式在句子中作状语,表示方式或伴随情况。
①The little girl stood there,crying for milk.
这个小女孩站在那儿,哭着要牛奶喝。
②He worked late into the night,preparing an important report.
他工作到深夜,在准备一个重要的报告。
③The teacher stood at the entrance,blocking the children’s way.
老师站在入口处,挡住了孩子们的路。
12.(高考四川卷)The lawyer listened with full attention,________to miss any point.
A.not trying     B.trying not
C.to try not D.not to try
解析:选B。句意:这名律师全神贯注地听,尽力不错过任何要点。本题考查非谓语动词作伴随状语。不定式作状语时和前面的部分如用逗号隔开,表示意想不到的或事与愿违的结果,不定式前通常加only或never,所以动词不定式在结构和题意上都不符合本题的要求,D项被排除;A、C两项结构错误,也被排除。
【即境活用】
13.(高考重庆卷) The news shocked the public,________to great concern about students’ safety at school.
A.having led     B.led
C.leading D.to lead
解析:选C。句意:这条新闻使广大民众感到很震惊,引起了人们对在校学生安全的担忧。考查非谓语动词作结果状语。首先排除B和D两项; having done指动作先于谓语动词发生,在此不符合语境,故只能选择C。
② 【教材原句】 Whatever you’re doing when you want to smoke―do something else!(P19)
无论你在做什么,当你想抽烟时,做点别的事吧!
【句法分析】 考查whatever的用法。(1)引导让步状语从句,在从句中作主语或宾语,其含义相当于no matter what,意为“无论,不管”,其位置可在主句前,也可在主句后。
(2)引导名词性从句(宾语从句或主语从句),可看作是what的强调说法,其含义相当于anything that 或all that,whatever在句中起双重作用,既起先行词与关系代词的作用,又在从句中作主语、宾语等。
(3)however/whenever/wherever只引导让步状语从句,相当于no matter how/when/where引导的从句。
(4)whoever/whichever同whatever一样,既能引导状语从句也能引导名词性从句。
①Whatever he did,his parents supported him.
=No matter what he did,his parents supported him.
不管他做什么,他父母都支持他。
②I don’t believe whatever he said.
我不相信他说的一切。
③I’ll take whatever help I can get.
任何帮助我都接受。
14.(高考浙江卷)―How about camping this weekend,just for a change?
―OK,________you want.
A.whichever      B.however
C.whatever D.whoever
解析:选C。句意:“这个周末我们换一下去野营怎么样啊?”“好的。你想做什么就做什么。”答语为省略句式,全句应为:OK,whatever you want to do.whichever 不论哪个;however无论怎样;whatever无论什么,不管什么;whoever不论是谁。
【即境活用】
15.The lawyer seldom wears anything other than a suit ________the season.
A.whatever      B.wherever
C.whenever D.however
解析:选A。句意:无论什么季节,这位律师除了一套西装以外,很少穿其他的(衣服)。whatever引导让步状语从句,whatever the season即whatever the season is。wherever无论什么地方;whenever无论什么时候;however无论怎样,均不符合语境要求。
