Although B. Because C. Whether D. Unless ‎【解析】本题答案是A。根据主从句的句意:虽然John几次都未能爬到山顶,但他没有放弃。这是although引导的让步状语从句,所以选A。‎ ‎【例2】Keep an English diary,________ your English will improve. ‎ A. or B. since C. when D. and ‎【解析】本题答案是D。本句的知识点:祈使句,and/ then/or +一般将来时的简单句。其中“or”解释为“否则”,“and/then”解释为“然后”,根据句意选择D。‎ ‎【例3】We should leave early tomorrow morning,________ we won't get there on time.‎ A. so B. but C. or D. and ‎【解析】答案是C。连词or在句中表示“否则,不然”,转折所导致的结果;so表示结果;前后对应,and是并列关系的连词;but表示转折与上文相反。‎ ‎【例4】Bill won't make any progress ________ he studies harder than before. ‎ A. so B. when C. because D. unless ‎【解析】答案是D。根据句意结果是不会取得进步,四个选项的关系so所以,表示结果;when当……时候,表示时间;because因为;unless如果不,除非,表示条件。‎ ‎【例5】________ Tom ________ Mary is busy at the moment. You'd better play with others.‎ A. Both; and B. Not only; but also C. Neither; nor D. Either; or ‎【解析】本题答案是B。首先根据动词is ‎ busy单数形式可排除A选项动词用复数。根据下文意思分析,此刻两个人都很忙,不能和你玩。而C选项是否定意义,两个人都不忙,D选项表示两个人中有一个人忙,可以和你玩。这是极容易错的典型题。‎ ‎【例6】The cyclist held his raincoat tightly ________ the wind couldn't blow it away. ‎ A. so B. so that C. when D. because ‎【解析】本题答案是B。首先要考虑上下文的关系,不是因果关系,所以排除A和D。紧紧抓住雨衣目的是为了防止刮走,而C是表示时间的连词。‎ ‎【例7】Peter was late for the meeting ________ he missed the ferry. ‎ A. though B. because C. while D. if ‎【解析】答案是B。本句上下文是因果关系,上句是结果,下句表示原因,故用because。四个选项都是引导状语从句的从属连词而不是并列连词。though是转折关系的从属连词;while用来表示转折关系;if表示假设的条件,不符合句意。‎ ‎【例8】 Which would you like to buy,a DVD player ________ an MP3 player? ‎ A. so B. or C. but D.and ‎【解析】答案是B。本句是选择疑问句,是“特殊疑问句,A or B?”结构。提供两种情况,询问对方选择哪一种。‎ ‎【例9】Mr. Li is our teacher and friend as well.(保持句意基本不变)‎ Mr. Li is ________ only our teacher ________ also our friend. ‎ ‎【解析】答案是not only…but also。根据句意,as well是“也是”的意思,而not only...but also是固定词组,表示“不仅……而且”,与句意吻合。‎ 三、学法提炼 ‎1. 专题特定:连词是选择,完形中常考。熟练地连词使用,对写作也有提升。‎ ‎2. 解题方法:连词看似简单实则易错。特别要提醒同学注意的是必须掌握每个连词的用法,认真仔细地思考、分析和判断,这样才能从四个选项中通过排除三个错误的选项选出正确答案。杜绝有些同学没有经过完整的思考,题目只读到一半的时候就填写答案。‎ ‎3. 注意事项:注意使用连词后,哪些谓语动词用单数,哪些用复数。‎ 学法升华 一、 知识收获 ‎1. 本单元学习了哪些重要短语?‎ accept others’ advice 接受别人的建议 think twice (about sth ) 三思而行 be /get angry with sb 生某人的的气 be /get angry at/ about sth 因某事而生气 worry too much担心太多 be patient / impatient with 对……有/ 没有耐心 not only ……but (also )…… 不但……而且…… (就近原则)‎ do the dishes 洗碗,洗餐具 animal signs 生肖 appear in a fixed order 按照固定的顺序出现 make his lesson lively and interesting使他的课上得生动而有趣(lively活泼的,生气勃勃的指人或物)‎ It’s said that 据说 make a speech = give a speech 作演讲 do extra work 做额外的工作 win several science competitions 赢得几项科学竞赛 get himself more organized 使他自己更加有条理 be absent from school 缺席 ‎ recommend sb as… 推荐某人为/当…‎ recommend sb for… 推荐某人获…奖 agree with sb 同意某人的看法、意见; 适应(食物、气候)‎ find it difficult to work with him find it +adj.+to do sth 发现做某事….‎ be formed by both nature and the environment天生和后天环境形成的 be passed onto you by your parents有你的父母遗传给你 liveliness and impatience活泼和急躁 二、 方法总结 ‎1. 如何理解句子:Neither my parents nor I think I can make a good accountant.?‎ 翻译为:我和我父母都不认为我能成为一名优秀的会计。Neither...nor翻译为既不...也不...;两者都不。make 除了有“制造”,“做”,还有“成为”的意思。‎ ‎2. 如何理解句子:It's terrible for me to work without speaking all day long.‎ 翻译为:对我来说,整天工作不说话太可怕了。Without翻译为“没有”,“不”,后接ing, It is +adj.+for sb+to do sth为固定句型,翻译为:对某人来说做某事是...的。‎ 3. 如何理解句子:All of us know that it's necessary to pay attention to every detail.‎ 翻译为:我们所有人都知道注意每个细节的必要性。pay attention to为“注意...”,know后接一个宾语从句。‎ 三、 技巧提炼 正确理解英文文章有哪些技巧?‎ 而要做到正确理解原文,就需要有扎实的英语语言基础,特别是英语句型结构知识和正确分析英语句子结构的能力。‎ 课后作业 作业1:整理错题 作业2:单项选择 ‎1.

Many people in Western countries think so. Scientists at the University of California, Berkeley (UC Berkeley), did a study on cat colours and people’s understandings of cat personalities. ‎ The study found that people do judge(判断) cat personalities by color. Scientists did a survey on the Internet. There were 49 statements (描述) matching five cat colorings with 10 personalities. People think orange and bi-coloured (双色的) cats are friendly, tri-coloured (三色的) cats are not generous, and white cats are calm, lazy and shy. As for black cats, people think they don’t have special personalities. ‎ But why do so many people dislike keeping black cats as pets? People think black cats have less special personalities, which might be because of their bad reputation (口碑). They think black cats may bring bad luck, especially at Halloween. Movies and television shows also make people believe that.‎ Although people have these ideas, UC Berkeley scientists give another reason: people don’t think black cats are pretty enough. After all, nothing can show black cats are unluckier than other cats. “You can’t judge a cat by its colour, because it’s the personality of the cat, not the colour, that will let you know if the cat is right for you,” Cathy Marden, a scientist said.‎ ‎( )1.

The main idea of paragraph 2 is that    .‎ ‎ A. people often complain about black cats on the Internet ‎ B. people think cats of different colours have different personalities ‎ ‎ C. black cats are less popular than other cats ‎ D. the study is a great success ‎( )3. According to the study, people think that    .‎ ‎ A. black cats have special personalities ‎ B. orange and bi-coloured cats are generous ‎ C. cats with three colours are friendly ‎ D. white cats are calm, lazy and shy ‎( )4. People don’t like black cats for the following reasons EXCEPT    .‎ ‎ A. black cats often appear in TV shows ‎ B. black cats bring bad luck to people ‎ C. black cats have bad reputations ‎ D. they don’t think black cats are beautiful ‎( )5. The passage mainly talks about    .‎ ‎ A. why black cats are popular in movies ‎ B. why people are not willing to keep black cats as pets ‎ C. different colour cats have different personalities ‎ D. different people have different ideas on black cats ‎ B The size and shape(外形)of your ears show your character(性格)more than any other part of the face. Other parts of the face change shapes as we get older, but ears do not change their shapes. They only change in size.‎ Reading people’s character from their ears is a very old science. In the past people thought that a person’s ears with colour was dangerous. They also thought that the shape of the ears showed if a person was musical or not. Today, too many people believe that the size and shape of the ears help you know if a person is musical.‎ Ears are all different, and each different thing has a meaning. Next time you look at a person, see if his or her ears are large, medium-size, or small. Look at the lobes(耳垂). Do they stick to the face? Ears that are always red mean that a person may get angry easily. Ears that are always cold and nearly white colour mean that a person has a nervous(神经质)character.‎ ‎1.
