三、重点句型
1.So many thousands of terrified people died every time there was an outbreak.
每当(疾病)突发时,总有成千的人死去
【句型剖析】 1)本句是一个复合句,every time引导的是一个时间状语从句,意思是“每当……”,相当于“when”。 另外,此状语从句中还有一个“there be”结构。
2)So many thousands of terrified people died是主句。
【归纳拓展】 类似的时间状语归纳:
1)each time 每次;每当
2)at the time 在……时候
3)any/next/the first/the last time 意为“任何/下一次/第一次/最后一次”
4) the moment, the minute, the second, the instant, immediately, directly, instantly等都可以引导时间状语从句。意为“一……就”

2.He became interested in two theories that possibly explained how cholera killed people.
他对两个可能解释关于霍乱为什么能致人于死地的理论感兴趣
【句型剖析】 1)how 引导的特殊疑问句是宾语从句。
2)he became interested in two theories explaining是主句。
3)主句是“主系表”结构:
become在此处为系动词,意为“变得;成为”,表示的是动态过程,become ill表示“患病;得病”。通常
be+形容词意为“病了;病着”,则表示静态。
除此之外,常见的系表结构还有:get tired意思是“感觉累,感觉疲惫”;get happy, get angry;get lost(迷路);get married(结婚);get used to(习惯于);get tired(累了);get dressed(穿好衣服);get angry(发怒) 。 “turn+形容词”,“become+形容词”, “keep+形容词”。如:turn white(变白), become fatter and fatter(变得越来越胖), keep open(保持开着) 等等
【归纳拓展】1)在英语中,陈述句、一般疑问句和特殊疑问句都可以在宾语从句中充当宾语,但一定要用陈述语气 如:I don’t know what will happen in future.(由特殊疑问词引导)
I wonder whether he lives here.(由whether或if引导)
He told that he was very sad at that moment.(由that引导,that可以省略)
2)和系动词get组成的常见搭配有:
【高考链接】Cleaning women in big cities usually get _____ by the hour.(NMET 1998)
A. pay B. paying
(答案:C)
3. The first suggested that cholera multiplied in the air.

② suggest sth. to sb. 向某人提议……。例如:

③ suggest (to sb.) that-clause (向某人)建议。例如:

② suggest + that-clause 暗示、表明……。例如:

③ suggest sth. to sb. 使某人想起……。例如:
An idea suggests itself to me. 我想到一个主意。
[思维拓展] suggestion, advice, proposal均作“建议”讲,所接同位语从句和表语从句也要用虚拟语气。例如:
My suggestion is that we (should) go to the cinema together.
我建议我们一块儿去看电影。
My advice is that you (should) stay here for another week.
我建议你在这儿再待一个星期。
[典例]1)The parents suggested ___ in the hotel room but their kids were anxious to camp out during the trip.(2006上海春招)
A. sleep
[解析] suggest doing sth.
4. Only if you put the sun there did the movements of the other planets in the sky make sense.
只有把太阳作为(太阳系)的中心,其他星球的运动才讲得通
【句型剖析】 1)if 引导状语从句表“只有”。
2)only 放在句首用来加强语气。
3)以only引导的短语作状语或状语从句放在句首时,为了加强语气,句子需要部分倒装。如:
Only by working hard can we succeed.
只有通过努力工作,我们才能取得成功
【归纳拓展】 1)only 后如果后续的不是状语时句子不倒装,切忌!如:
Only with him, she can do it well.她只有和他合作,才能把它做得好。
2)倒装分为全部倒装和部分倒装两种:全部倒装是指将句子中的谓语动词全部置于主语之前;部分倒装是指将谓语的一部分,如助动词或情态动词放在主语之前。如:
Then came the chairman.(全部倒装)
Never have I seen such a performance.(部分倒装)

五、语法聚焦
过去分词作定语和表语
(The Past Participle as the Attribute and the Predicative)
分词是动词的一种非谓语形式,主要起形容词和副词的作用,可以作定语、表语或是状语等 分词有两种,一种是现在分词,一种是过去分词。这两种分词在句子中能担任的成分大体相同,主要是在“意思”上有主动和被动之分。过去分词一般有被动和完成两大特征。
过去分词的定语和表语功能
定
语 |
表“完成”或“被动” |
boiled water开水 the
risen sun升起的太阳 spoken English英语口语 iced beer冰镇啤酒 cooked food熟食 |
单个的过去分词作定语时, 一般放在被修饰词语之前 (如上例),也可以放在所 修饰词语的后面 |
Hurry up,there is only a little time left. 快点,时间不多了。 If you wish everything changed,please say so. 你如果希望改变一切,请说明。 |
|
过去分词短语作定语时,须将分词放在被修饰的词语之后,功能相当于一个定语从句。 |
Near the window,there is a bookshelf filled with many books(=which is filled with many books). 靠近窗户,有一个装满书的书架。 Her daughter,brought up by me(=who was brought up by me)has begun to work now. 由我带大的她的女儿现在已经参加工作了。 |
|
表 语 |
当“人”作主语时用过去分词作表语,表示主语的状态或思想感情等。 |
When we heard of it,we were deeply moved. 当我们听到这件事时,被深深地感动了。 He seemed quite delighted at the idea. 听到这个想法,他似乎很高兴。 |
过去分词作表语不要与被动语态混为一体。分词作表语表示主语的状态,而被动语态则表示被动的动作 |
My glasses are broken.我的眼镜碎了。(状态) My glasses were broken by my son. 我的眼镜被我儿子摔碎了。(动作) On the earth,70% of the surface is covered with water.地球表面70%是被水覆盖的。(状态) I was greatly surprised by a knock at the door. 敲门声使我大为吃惊。(动作) |
