自主探究
Whose book is this ( http: / / www.21cnjy.com )It must be Mary’s. J.K. Rowling is her favorite writer.
这是谁的书?它肯定是Mary的。因为J.K. Rowling是她最喜爱的作家。
【解读一】 本句中must意为“肯定,一定 ( http: / / www.21cnjy.com )”,表示对现在的情况进行推测,语气很强,较有把握。情态动词must表推测只能用于肯定句。must表示推测时的否定式是can’t或couldn’t(不可能,一定不),此处can’t和couldn’t没有时态的区别。
【举例】(1)The light is still on, so he must be at home. 灯还是亮的,他一定在家。
(2)He can`t know my address. 他肯定不知道我的地址。
【练习】根据中文完成句子。
(1)走了这么长的路,你一定很累了。You _______ _______very tired after the long walk.
(2)他不可能在家。他去上海了。 He at home. He has gone to Shanghai.
【解读二】 must表示推测 “可能性”时 ( http: / / www.21cnjy.com ),语气很强,较有把握,而could和might表示把握性不大的推测,意为“可能、也许”, might的可能性比could更小。情态动词表推测巧记乐记口诀:must句中表推测,表示某事会必定;might, could来推测,语气不如must;否定推测“不可能”, 只有can’t才能行。
【举例】(1)It could rain tomorrow according to the radio report.
据电台报道,明天可能会下雨。
(2)The hair b ( http: / / www.21cnjy.com )and might / could belong to Gina , because she has long hair.
这个发箍可能是Gina的,因为她留长发。
【练习】选择最佳答案。
(3)—Susan’s parents have bought a large house with a swimming pool.
—It _____ be very expensive.
A. must B. can C. mustn’t D. may not
(4)Henry _____ be a ( http: / / www.21cnjy.com )t home because he phoned me from the farm just now.
A. mustn’t B. isn’t able to C. may not D. can’t
(5)—Whose red bac ( http: / / www.21cnjy.com )kpack is this —It _____ be Tom’s. His backpack is red.
A. might B. need C. must D. can’t
2. I think somebody must have picked it up.我想有人肯定把它捡起来了。
【解读】此句中must ha ( http: / / www.21cnjy.com )ve picked it up意为“肯定已经捡起来了”, 是对过去的情况进行推测,基本结构是:must + have done,把握较大;而表示可能性不大的推测时,用could / might + have done。
【举例】(1)This cake is ve ( http: / / www.21cnjy.com )ry sweet. You must have put a lot of sugar in it.
这蛋糕很甜。你肯定放了很多糖。
(2)He might not have got your letter. 他或许没有收到你的来信。

自主探究
There must be somet ( http: / / www.21cnjy.com )hing visiting the homes in our neighborhood, but what is it
一定有什么东西拜访了我们周边的家庭,可那是什么呢?
【解读】there be ( http: / / www.21cnjy.com )结构后面如果有动词,只能用非谓语动词形式:V-ing或者V-ed形式取决于与前一名词的主被动关系。比如这句中something 和visit是主动关系,所以用visiting,如果是被动关系就用V-ed形式。
【举例】(1)There is very loud music coming from the apartment next door.
隔壁公寓里传来很响的音乐声。
(2)There must be something done by him. 肯定有他干的一些事。
【练习】根据中文意思完成句子。

(3)现在还剩下五分钟。There are five minutes ____________now.
The noise-maker is h ( http: / / www.21cnjy.com )aving too much fun creating fear in the neighborhood.
这个噪音制造者正为营造恐慌气氛高兴着呢。
【解读】 have fun doin ( http: / / www.21cnjy.com )g sth. 意为“做某事很开心”,相当于have a good / great / wonderful time doing sth.。have + n. + doing的结构还有have difficulties/ difficulty / trouble/ problems doing sth., 意为“做某事有困难”。
【举例】(1)We had great fun riding our bicycles to the beach.
我们今天骑自行车去海滨玩得很开心。
(2)We have difficulties understanding what he says.
我们要理解他的话有困难。
【练习】根据中文意思完成句子。
(1)我认她的笔迹有点困难。I _________ some __________ _________ her handwriting.
(2)我们在海里戏水玩得很开心。
We ________ ________ great________ ________ with water in the sea..
Sally has been coughing a lot. Sally 已经咳了很久了。
【解读】has been coughing是现在完成时态,表示动作从过去某一时间开始,一直持续到现在,或者刚刚终止,或者可能仍然要继续下去。其构成为:主语 ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网" \t "_blank )+助动词(have/has)+been+V-ing+其他成分。(与since,for连用时,常常表示动作会进行下去)
【举例】(1)The Chinese have been making paper for two thousand years.
中国有2000年的造纸历史。(动作还将继续下去)
(2)I have been learning English since three years ago.
自从三年前以来我一直在学英语。(动作还将继续下去)

1 带相机的妇女 3 穿着西服
2 为锻炼而跑步 4 赶公交车上班
自主探究
1. He could be running for exercise. 他可能为了锻炼身体在跑步。
【解读】句中 could 意为 ( http: / / www.21cnjy.com )“可能”,表猜测。be running 进行时,强调动作正在进行,could be running表示说话时“可能正在进行的动作或存在的状态”,如果用might, 可能性更小。如果猜测时把握较大,表达“肯定/一定在做某事”,则用must be doing sth.。如果表示“肯定/一定不在做某事”,要用can’t be doing sth.
【举例】(1)She could be coming here.她可能正在来这里(的途中)。
(2)He must be doing his exercises in the classroom.他一定在教室里做习题。
【练习】根据中文意思完成句子。

【解读】not on ( http: / / www.21cnjy.com )ly…but also意为“不但……而且……”,用来连接两个对等的成分,即not only 与 but also后面所接的词类要一致,also可以省略。如果连接两个主语时,谓语动词遵循“就近原则”,即取决于but (also)后的主语。如果连接两个分句,并且 not only 位于句首时,第一个分句中的主语和谓语要部分倒装。
【举例】(1)He is learning not only English but (also) French. (连接两个宾语)
他不但在学英语,而且还在学法语。
(2)I not only play tennis but also practice shooting. (连接两个谓语动词)

【解读】 some….others….意为“一些人……,另一些人……”或“有的……,有的……”表示两种情况的对比。
【举例】(1)There are ma ( http: / / www.21cnjy.com )ny people in the park. Some are playing football, others are singing. 公园里有很多人,一些人在踢足球,另一些人在唱歌。

自主探究
The sweater must b ( http: / / www.21cnjy.com )e Carla’s. She is the only one who wears such colorful clothes.
这件毛衣肯定是Carla的。她是唯一穿这么鲜艳衣服的人。
【解读】who wears s ( http: / / www.21cnjy.com )uch colorful clothes是一个定语从句,相当于形容词,修饰the only one.这里的one不是数词,而是代词,代替单数的人,所以这个定语从句中的谓语动词用第三人称单数形式wears. 如果没有the only修饰,定语从句中的谓语动词要用复数形式。
【举例】(1)He is t ( http: / / www.21cnjy.com )he only one of the teachers who knows French in our school.
他是我们学校唯一一个懂法语的老师。(修饰the only one,谓语动词用knows)
(2)He is one of the teachers who know French in our school.
