【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

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】

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)

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。
