【重、难点讲解】
一、重点词汇
   1.million n.百万
 要注意的是:million与hundred,thousand,billion(十亿)的用法相同:
当前面有别的基数词如one,two,three,four……时,即“若千百万”时,其本身都不要加s,如:three million students
若表示:“成百万”时,前面不能有基数词,但其本身要用复数形式,然后+of+名词复数。如:hundreds of millions of(数以千百万的…...)
正误判断
我们这个城市有大约两百万工人.
 [误] there are about two millions workers in our city
 [正] there are about two million workers in our city
 [析]几百万的表达法是基数词加million,而且不要加s.
    这样的单位还有billion,hundred,thousand,dozen(打),score(20年)等。
(2)中国有数以百万计的老年人钟爱并练习气功.1234
  [误] in china there are million of old people loving and doing“qigong”.
  [正] in china there are millions of old people loving and doing“qigong”.
 [析]当表达数百万时,要用millions of这一结构。
2.come up with 提出;想出
 come up with=find or produce(an answer)意思是“找到,提出(答案、解决方法等)”。这是动词和介词一起构成的固定词组,一般称为短语动词。又如:
 the teacher asked a difficult question,but finally john came up with a good answer.
老师问了一道难题,但是最后约翰还是做出了一个很好的回答。
he couldn’t came up with an answer when i asked him why he was late.
当我问他为什么迟到的时候,他答不出来。
one day,adison came up with an good idea.
有一天爱迪生想出了一个办法。
3.in the slightest 一点(不);根本
 in the slightest通常用在否定句中,not in the slightest=not at all表示“毫不;一点也不”
eg.you didn’t bother me in the slightest.
   你一点也没有打扰我。
  there is not the slightest reason.
   毫无理由。
4.plenty of很多的;足够的
1)plenty of=many用来修饰可数名词
   eg.there is plenty of eggs in the fridge.
2)plenty of+much用来修饰不可数名词
   eg.don’t worry.there is plenty of time left.
   注意:a number of,a great many也表示“很多”但只能用来修饰可数名词
二、重、难点句子
1.but if you are still nervous,you don’t have to go.
 但是,如果你依然紧张,你就不必去了。
  don’t have to=don’t need to=needn’t表示“不必”.又如:
  —must i bring a present?
 我必须带礼物吗?
  —no,you don’t have to.
 不,不必.
2.what if everyone else bring a present?
 要是别人都带礼物怎么办?
  what if=what would happen if…?
  要是……又怎样?
eg.what if it rains when we can’t get under shelter?
  假如下起雨来,我们又没处避雨怎么办。
3.you like talking to one or two people rather than to a group.
  你喜欢和一个人交流,而不是和一群人。
  rather than=in preference to(sb/sth);instead of与其(某物/某事物);不愿;不要;不是
eg.i think i’ll have a cold drink rather than coffee.
  我想喝冷饮,不想喝咖啡。
  rather than risk breaking up his marriage,he told his wife everything.
  他唯恐婚姻破裂,把一切告诉了妻子。
4.he divided them into two teams of nine and taught them how to play this new game.
 他把他们分成九人一组,教他们如何玩这种游戏.
  divide…into…=(cause sth to)breake into parts;separate把……分开;分隔
 eg.they divided a large house(up)into flats.
 他们把一所大房子分隔成若干套间.
 we must divide the class(up)into small groups.1234
 women必须把那个班分成几个小组。
 
三、语法
虚拟语气   subjunctive mood(一)
虚拟语气在条件从句(protasis)中的用法:
条件从句有两类:
真实条件句;
虚拟条件句。
如果假设情况有可能发生的,就是“真实条件句”。
eg.if time permits,we’ll go fishing together.
  如果有时间的话,我们就一起去钓鱼。
如果假设的情况与事实相反,则为“虚拟条件句”。
eg.if it had rained yesterday,we would have stayed at home.
  如果昨天下雨的话,我们就会留在家里。
(事实是:昨天没有下雨,我们外出了)
一)虚拟语气在非真实条件句中的应用
阅读:
1.if i were you,i’d wear a shirt and tie.
2.if we had found her address,we would have written her.
3.what would you do if you won the lottery?
4.what would you do if there should be(were to be)an accident?
5.if it had not been for your help,we should not have succeeded.
6.if we had been given more time,we could have done it better.
7.if you had not helped me,i wouldn’t have passed the exam.
 
 
提示:
   1.在从句中,be动词多用were的形式。在口语中,如果主语是第一、第三人称单数的话,be动词可用was,但人们总是说:if i were you…
   2.主句中的谓语可以由would,should,could和might这四个不同的情态动词来构成。
   3.与将来事实相反的条件从句中,谓语有三种不同的形式:过去式、were+to do或should+do。
实例解读:
 与现在事实相反的假设(事情的发生都在同一时间内);
 1.if i were you,i should buy it.
  (如果我是你,我就会买了它。)
  (从句用过去式动词were,主句用should buy)
 2.if i had time,i would study french.
  (如果有时间,我会学习法文。)
  (从句用过去式动词had,主句would study)
 3.if she knew english,she would not ask me for help.
  (如果她懂英文,她就不必要我帮了。)
  (从句用过去式动词knew,主句用would not ask)
 与过去事实相反的假设(假设从句的事实为过去的事):
 1.if you had studied harder last term,you could have passed exam.
 (从句动词用had studied,主句动词用could have passed)
  如果你在上个学期用功一,你就会在考试中过关了。
 2.if you had taken my advice,you wouldn’t have failed in the exam.
 (从句动词用had taken,主句动词用wouldn’t+have failed)
  如果你当时听从我的劝告的话,你就不会在考试中失败了。
 3.if it had snowed,i would have skied in the park.
  (从句动词用had snowed,主句动词用would have skied)
   如果下雪的话,我就可在公园里滑雪了。
 与将来的事实可能相反(对将来的事实实现的可能性不大):
 1.if it should rain,the crops would be saved.
  (从句动词用should rain,主句动词用would be)1234
   如果天下雨,庄家可能就收获了。
 2.if he were to go tomorrow,he might tell you.
  (从句动词用were to,主句动词用might tell)
   如果明天他走的话,他可能会告诉你。
 3.if he were here,i would give him the books.
  (从句动词用were,主句动词用wouldgive)
   如果他在这儿,我可能会把书给他。
