2、事。2）be sure to do用在祈使句中，不是表示判断，而是表示对对 方的要求，意为“务必要”，“一定要”。Be sure to send my regards to your mother务必代我问候你母亲。Has it arrived yet?已经到了吗？Yes, it has arrived already是的，已经到了。yet意为“还；尚”，用于表达某事在某一时间内尚未发生，但未 也许会发生。在现在完成时中，通常用在否定句和疑问句中。Have you received his letter yet?你已经收到他的信了吗？They havent finished their mat

4、yet疑问、否定有关系， already用于肯定莫迟疑。So have they discovered life on Mars? 那么他们在火星上发现生命了吗？discover是及物动词，表示“发现，了解到”，指“发现或找到”某种 自然界本已存在，但以前未被人类发现或认识的事物，如发现元 素、电、煤、石油、铁等矿藏以及新星、星系或科学真理等。I discovered an unopened letter in the drawer我在抽屉里发现了一封未拆的信。Lots of scientists are working hard in order to send astronauts to

6、 to get there in time=He got up early so that he could get there in time为了及时赶到那里，他很早就起床了。2）in order that后接句子，引导目的状语从句，意为“以便;以至于”。In order that I could hear clearly，he spoke loudly again为了让我听清楚，他又大声地说了一遍。Unit 2 We have not found life on any other plas yetthere has been life on earth for hundreds of m

7、illions of years地球上存在生命已经有成千上万年了。There be句型的现在完成时 There has been是There be句型的现在完成时形式。若be动 词后面的名词是复数，则用There have been。There have been many people on the playground by now 到目前为止操场上已经有许多人了。There be句型现在完成时的否定句形式为There havent/hasnt been ; 般疑冋句形式为Have/Has there been?Have there been visitors to the earth f

8、rom other plas? 已经有自其他行星的游客拜访地球了吗？There hasnt been any milk yet 已经没有牛奶了。hundreds of millions of 成千上万的hundreds of意为“成百上千的” ；millions of意为“成千上万的”； 放在一起时仍然指不确定数“成千上万的”。Millions of people visit the Great Wall every year每年都有成千上万的人参观长城。（1）与之用法相同的短语还有thousands of“数以千计 的”，billions of“数以亿计的”。（2）当 hundred（百），

9、thousand（千），million（百万），billion（十亿） 和具体数字连用时，hundred，thousand，million，billion等不变复 数，不加介词of;若没有具体数字时，必须变复数，加介词of。He spent three hundred dollars on the books他花了三百美元买这些书。There is a big sale in the shop Thousands of people are waiting to buy cheap things这个商店大减价。成千上万的人等着买便宜货。【即学即练】一、单项选择。1 Taiyuan is bei

10、ng a tourist city B people e here during the holiday every yearA Thousand ofB Thousands of C Five thousands of解析句意为“太原正在变成一个旅游城市。成千上万 的人每年在假期期间这里。” A项本身错误，应是 Thousands of; C项中thousand不应加复数，也不需要介词 of；B项意为“成千上万的”。故选B。2 Six B students in our school are from the countrysideA hundredsB hundredC hundreds

11、of解析句中有具体的数词six，所以hundred不用复数，选B。3 Ten teachers and students plant treesevery yearA thousands; million of B thousand; millions of C thousands of; millions of 二、根据汉语意思完成句子。1 以前这个超市从未有过这么多人。2到目前为止，已经有到这个博物馆参观的游客了吗？However, we have not found life on any other plas yet 然而，我们还没在任何其他的星球上发现生命。have not foun

12、d是现在完成时的否定形式。现在完成时的否定 句形式为have/has + not +动词的过去分词，其中have/has和 not 可以缩略为 havent/hasnt。We havent been to Shanghai我们没有去过上海。有时我们也可在have/has之后加 never构成否定句。He has never heard of the news before他以前从未听说过这个消息None of them has an environment like that of the earth, 它们当中没有一个有像地球上那样的环境，none 没有一个none作代词,意为“没有一个,一

13、个也没有;没有一人”，是表示 否定的不定代词，既可指人也可指物。none of作主语时，如指 代不可数名词，谓语动词要用单数形式;指代可数名词，谓语动 词用单、复数均可。None of the money belongs to me 这些钱没有属于我的。None of them has/have seen me before 当中没人以前见过我。no one/nobody常用指人，作主语时谓语动词要用单 数形式;nothing常用指物，作主语时谓语动词也要用单数形式。但它们都不可以和of短语连用。No one likes a person with bad manners没人喜欢没有礼貌的人。

14、Nothing is difficult in the world if you put your heart into it世上无难事，只要肯攀登。1 of us has read the story So we know nothing about itA NoneB NothingC BothD All解析本题考查代词。由代词us可知，本题的主语是人， 可排除B; 由So we know nothing about it “因此我们对此 事一无所知”可知选A。2Im thirsty I want to drink some water，but there was in the bottl

15、eA nothingB noneC notD no句意为“我口渴了。我想喝水，但 是瓶子里没有。”这里的代词是指“物”的，所以选A。However, no spaceship has travelled far enough to reach near other stars in our Galaxy 但是，还没有宇宙飞船飞得足够远可以到达银河系中较近的其他星球。本句中far enough to reach意为“足够远可以到达”。“enough to do sth”意为“足够可以做某事”，其中enough是副词，用修饰形容词或副词，但形容词或副词必须放在 enough之前，enough之后加

16、动词不定式（to do sth），意为“足够可以做某事”。He is old enough to go to school他足够大可以上学了。“so +形容词/副词+ that从句”意为“如此以至于”；“too +形容词/副词+to do sth”意为“太而不能”，以上两个句型可以与enough to do sth互相转换。The box is too heavy for me to carry这个箱子对我说太重了搬不动。The box is so heavy that I cant carry it这个箱子如此的重以至于我搬不动它。The box is not light enough fo

17、r me to carry这个箱子对我说不够轻，我搬不动。1 He is to lift the heavy bagA too weakB weak tooC weak enoughD enough weak 解析本题考查too to结构和enough to结构的区别。 从语法上判断，B和D项错误；从句意上判断选A。句意 为“他太弱小了拎不动这个重包。”2 He wasnt with his knife He cut himselfA careful enoughB enough carefulC carefully enoughD enough carefully解析本题考查enough的用

18、法。enough修饰形容词或副 词时，要放在其后，所以排除B和D; 根据句中的wasnt可 知，其后接形容词作表语，所以本题选A。二、同义句转换。1His brother is too excited to fall asleep2He is strong enough to climb the mountainWith so many stars in the universe, are we alone, or is there life out there in space? 宇宙中有这么多的星星，我们是唯一的吗？抑或太空中还有其他生命呢？介词短语表伴随 with so many sta

19、rs in the universe是介词短语，在句中作状语，表示伴随的情况。The boy ran in, with an apple in his hand男孩手里拿着苹果，跑了进。He waved at us with a smile on his face他面带微笑向我们招手。What does your English teacher look like?Shes tall and thin long hairA haveB hasC there isD with解析 with “带着；有的”，表示特征。句意为“你们英语老师长得什么样子？”“她留着长发，高高的，痩痩的”。Why ha

20、s no one municated with us? 为什么没有人和我们联系？municate是不及物动词，意为“联系;交流”，跟宾语时，要加介词with。municate with sb意为“与某人交流”。He had no way to municate with his brother他没有办法和他的弟弟交流。Unit 3 Language in use【热身训练】英汉互译1 any other plas 2arrive on Mars 3send back photos 4在月球上行走 5（将的）某一天 6等待消息 Ive just made a model spaceship我刚刚

22、可以用于疑问句，意 为“已经”（放在have和has的后面也可放在句末）。I havent found my ruler yet我还没有找到我的直尺。Have you found your ruler yet? 你已经找到尺子了吗？3） just只用于陈述句，意思是“刚才”（放在have和has的后面）。He has just had his meal 他刚吃过饭。单项选择1We havent finished our homework A alreadyB everC yetD never解析 本题考查副词。由于题干是否定句，所以用yet。2Have you learned English?

23、Yes, Ivelearned a lotA never; everB ever; neverC ever; alreadyD already; ever解析 问句中用ever意为“曾经”；答语是肯定句，用 already，所以本题选C。3Have you finished your homework ?Yes，Ive done thatA yet; alreadyB already; yet neverD still; just解析 yet用在疑问句句末，already用在肯定句句中。4Johns father borrowed some picturesA have alreadyB ha

24、s justC have everD have never解析句意为“约翰的爸爸刚借了 一些画。”根据主语为 第三人称单数可知，应选B。现在完成时的用法 II一、现在完成时的用法表示过去发生或已经完成的动作对现在造成的影响或结果，常 与just，already和yet等连用。already，just和yet表示“到现在 为止动作或状态已经、刚刚或还没有发生”。He has already got her help他已经得到了她的帮助。He has just seen the film他刚刚看了这场电影。誗He hasnt e back yet他还没有回。二、现在完成时与一般过去时的用法比较（1

25、）现在完成时表示过去的动作一直延续到现在甚至会继续 下去或表示过去的动作 江西中考）一Have you had your breakfast yet?Yes，Mom it for meA was cookingB is cookingC will cookD cooked解析 本题考查动词的时态。结合本题场景可知，“我”吃 过早饭了，所以妈妈是在过去的某个时刻为“我”做的早 饭，故要用一般过去时。（ 2018 广东广州中考）You look very nice in your new dress todayOh，really? I B it when it was on saleA buyB boughtC have boughtD will buy解析 本题考查时态。答语后句句意为“当它打折销售时我买的。”由从句为一般过去时可知主句的动作也应发生在过去，故用一般过去时。w
