二、要点讲评
1. I don’t think aliens can be found in space. 我认为外星人不可能出现在太空里。
(1)当think, believe, suppose, imagine, expect等动词后的宾语从句含有not的否定词时，该否定应移至主句，即否定主句的谓语动词。
如：I don’t think it will rain tomorrow.我认为明天不会下雨。
如果主句的主语是第二、三人称，否定式一般不转移。
如：He supposes they won’t win the game.他猜想他们赢不了比赛。
(2)can +be +过去分词，是情态动词构成的被动语态。
如：This can’t be done in a short time.这不是短期内能完成的。
2. It has been two days since we landed on Mars.自从我们登上火星以来已经两天了。
it用作主语谈论时间，常与since连用。
如：It is(或has been) three years since we left school.
自从我们离开学校以来已经三年了。
3. What’s worse, our water supplies were very low.更糟糕的是，我们的水供给是非常有限的。
What’s worse 更糟糕的是。类似结构还有：What’s more 更有甚者；更为重要的是。
4. It’s a quarter as big as the earth..它是地球的四分之一大。
倍数表示法：倍数+as+形容词/副词+as
如：This box is three times as heavy as that one. 这只箱子是那只箱子的三倍重。
5. Mars goes around the sun at a distance of about 228 million kilometers.
恒星在相隔大约228000000千米的地方绕着太阳转动。
(1)at a distance of 相隔
(2)at a distance在远处。
如：The moon goes around the earth at a distance of 380000km.
月球在距地球38万千米的地方绕地球旋转。
The police followed him at a distance.远远地跟着他。
6.情态动词的被动语态:是由“情态动词+be+及物动词的过去分词”构成。
如：⑴Aliens can not be seen on the earth.在地球上不可能见到外星人。
⑵Other planets may be visited soon in the future.
将来其他的星球也会有人登陆。
⑶Scientific research should be done carefully.应该认真地进行科学研究。
These trees must be watered in time.这些树应该及时浇水。
7.书面表达
善于衔接。一篇好作文不仅是词汇、句子的简单罗列，语句间如缺乏必要的连接过渡和照应，作文就会结构简单，句式单调，缺少灵气，而看似不显眼的衔接过渡可大大增强作文的连贯性，逻辑性和可读性。常见的语篇衔接成分见下表：
逻辑关系 | 语篇衔接成分 |
时间关系 | first(ly),second(ly),then, finally, suddenly, immediately, after, until, the moment, while
|
空间关系 | in front of, across, above, nearby, at the back of, next to, on one side…on the other side
|
对称关系 | on one hand…on the other hand, for one thing…for another |
转折关系 | but, however, yet, while, though, otherwise, rather than, no matter what ,on the other hand |
因果关系 | because of, thanks to, because, since, as, for this/that reason, as a result, so, therefore. |
条件关系 | as long as, if, unless, if necessary |
增补关系 | besides, in addition, not only…but also, as well, what’s more, what’s worse
|
举例 | for example/instance, such as, like, namely, in other words |
评价 | there is no doubt that, I’m not sure that, as far as I know, It’s certain that, as we know, It’s known to all that…, |
总结 | in a word, next to, in short, in general, in all, to sum up, Generally speaking, therefore
|
三、典型例解
( )1.Half a month _____ since I came to Beijing, I miss my students very much.
A.have passedB.have pastC.has passedD.has past
分析：C 时间段作主语时相当于第三人称单数，所以用has passed;而past是介词不能使用，故选C。
( )2.It is said that an old man lives on the _____ island _____.
A.alone; aloneB.alone; lonelyC.lonely; lonelyD.lonely; alone
分析：D 主要考查词的用法的区别。alone意为“单独的”，没有感情色彩，在句中只能作表语；而lonely意为“孤独的”，有感情色彩，在句中既可作表语又可作定语修饰名词。故选D。
( )3.To make our city more beautiful, rubbish _____ into the river.
A.needn’t be thrownB.mustn’t be thrown
C.can’t throwD.may not throw
分析：B 本题考查含有情态动词被动语态的否定式。needn’t 不必；mustn’t 禁止。故B项是正确答案。
( )4.The baby should _____ at home.
A.be taken careB.be taken care of
C.take careD.take care of
分析：B 考查情态动词的被动语态，排除C、D选项，这里介词of不能省略，of的逻辑上的宾语是the baby，故选B。
( )5.My son is too fat, so I have to _____ his food and drink.
A.saveB.limitC.encourageD.affect
分析：B save v. 挽救, 节省；limit v. 限定, ；encourage v. 鼓励；affect v. 影响。根据题意，选B。
( )6.Harry Potter and Sorcerer’s Stone is quite a good book. It’s worth _____.
A.readB.readsC.to readD.reading
分析：D be worth表示“值得”，后接名词或动名词。
( )7.Your car _____ be put here. Please put it over there.
A.can’tB.canC.mayD.may not
分析：A 本题考查情态动词的被动语态。根据题意：“你的车不能停在这里。”故选A。
( )8.Scientists are doing experiments in order _____ the Mars soon.
A.to exploreB.exploreC.that exploreD.to exploring
分析：A in order to 为了……，表示目的，后接动词不定式。
( )9.There _____ a man-made planet in space.
A.will beB.is going to haveC.has beenD.is
分析：A 本题考查There be的将来时态，其结构是There will be。
( )10._____ the help of the Internet, news can ______ every country of the world.
A.Under; arriveB.With; reachC.In; goD.With; get
分析：B 本题考查介词短语和动词。介词短语with the help of “在……帮助下”。reach在此表示“延伸到，到达”是及物动词，后直接跟名词或代词。
