26、件”，简单句表示“结果”，通常使用一般将来时。句型“祈使句and(表结果的)简单句”的意义 为“干 某 事，那 么 就 会”；“祈 使 句 or/or else/otherwise(表结果的)简单句”的意义为“干某事，否则就会”，连词or可用 or else/otherwise替代。Work hard and(If you work hard)you will pass your examinations.你若用功，考试就能及格。Arrive late once more and(If you arrive late once more)youre fired.你再迟到一次，就把你开除。Tur

28、电话，我会让你知道实验结果。由语境可知，此处是“祈使句and一般将来时态”这一固定句式结构，故B项正确。若选A项，理解成是现在分词作状语，则原句应为 Calling me tomorrow,Ill let you know the lab result；C项为动词不定式，放于句首要作目的状语，不合语境。D项having called为现在分词的完成时态，表示分词的动作发生在谓语动词之前；该三项均不合语境。(2)You have to move out of the way _ the truck cannot get past you.A.so B.or C.and D.but答案：B本题考查

29、连词的用法。句意：你需要离开这条车道，否则卡车不能从你旁边过去。so意为“因此”；and表示并列关系；but意为“但是”表示转折关系；or意为“否则，要不然”，符合语境，故B项正确。3One day as he was experimenting with one end of a straw joined to a deaf mans ear drum and the other to a piece of smoked glass,Bell noticed that when he spoke into the ear,the straw drew sound waves on the g

30、lass.有一天做实验，他把一根干草的一端和一个聋子的耳鼓膜连接起来，干草的另一端与一块被烟熏过的玻璃相连接。贝尔发现，当他对着耳朵说话的时候，这根干草就把声波画在玻璃上。本句的主语是Bell，谓语是noticed，that引导了一个宾语从句，在这个宾语从句中又有一个由when引导的时间状语从句；as引导一个时间状语从句，过去分词短语joined to a deaf mans ear drum作后置定语，修饰straw；the other to a piece of smoked glass是个省略句，可补充为the other end of the straw joined to a pie

31、ce of smoked glass。知识拓展并列句中的省略常有以下几种情况：如果主语不同，而谓语动词中的一部分相同，则省略谓语动词中相同的那部分。John must have been playing football and Mary(must have been)doing her homework.约翰一定在踢球，而玛丽一定在做作业。主语相同，谓语动词也相同，则二者都可以省略。His suggestions made John happy,but(his suggestions made)Mary angry.他的建议使约翰高兴，却使玛丽很生气。主语相同，而谓语不同，则可以省略主语。O

32、ld McDonald gave up smoking for a while,but(he)soon returned to his old ways.老迈克唐纳戒了一阵子烟，可很快又抽上了。在并列复合句中，如果that从句从属于第二个并列句且它的谓语动词和宾语等其他一些成分与第一个并列句相同时，这个that从句通常可以省略这些相同的部分。Jack will sing at the party,but I know John wont(sing at the party)杰克将在晚会上唱歌，但我知道约翰不会在晚会上唱歌。活学活用(1)The police still havent found

33、 the lost child，but theyre doing all they _.Acan BmayCmust Dshould答案：A考查情态动词与省略。句意：警察仍然没有找到那个失踪的孩子，但他们在尽他们所能去寻找他。can“能”，与句意相符。本句完整结构为：theyre doing all they can do to look for him。(2)It is worth considering what makes“convenience”foods so popular,and _ better ones of your own.Aintroduces Bto introduc

34、eCintroducing Dintroduced答案：C句意：什么东西使得“方便”食品如此流行值得考虑，引进你自己的更好的(方便食品)也值得考虑。introducing better ones of your own是“It is worth considering introducing better ones of your own”的省略形式。4But he found the problem difficult to solve.但是他发现这个问题很难解决。findn.(宾语)adj.(宾补)to do(to do作状语修饰adj.)是finditadj.(宾补)to do sth.

35、(it是形式宾语，to do sth.是真正的宾语)的变式注意：“to do”形式中当“do”为不及物动词时，应在后面加上适当的介词。并且动词不定式使用一般式。The man found the river dangerous to swim in.The man found it dangerous to swim in the river.这个人发现在这条河里游泳很危险。知识拓展find后的宾语可以是名词或代词，而补语则可由许多成分充当：(1)find宾语形容词/副词/介词短语。如：I seldom found him out.我很少发现他外出。When I woke up I found

36、 myself in a hospital.当我醒来时，我发现自己在医院里。(2)find宾语现在分词。如：They found the lost boy hiding in the cave.他们发现那个失踪的男孩藏在洞里。(3)find宾语过去分词。如：We found the place outside greatly changed.我们发现外面全变了。(4)find宾语名词。如：I find him an easy man to work with.我觉得他是个容易共事的人。活学活用(1)I found him easy _.Ato get along Bto be got alon

37、g withCto get along with Dget along答案：C句意：我发现他很容易相处。本题属于findn.(宾语)adj.(宾补)to do结构，在此结构中要求to do使用一般式，并且当do为不及物动词时，应加上适当的介词。因此只有C项符合题意。(2)I like getting up very early in summer.The morning air is so good_.Ato be breathedBto breathe Cbreathing Dbeing breathed答案：B句意：在夏季，我喜欢早起。呼吸早晨的空气有益于身心。本句还可以转换为：It is

38、 so good(for us)to breathe the morning air.不定式(短语)修饰作表语或补足语的形容词时，通常采用主动形式表示被动含义。(3)They found the lecture hard_；they all felt sleepy.Ato be understoodBfor understandingCto understandDto have been understood答案：C句意：他们发现这个讲座很难懂，所以他们都有恹恹欲睡的感觉。不定式修饰作表语或补足语的形容词时，如果和句子的主语之间构成逻辑上的动宾关系，不定式通常采用主动形式表示被动含义。如何写求

39、职信(Letter of application)写作指导求职信属于应用文中的书信类。写作时，要注意书信的一些基本格式。首先，要注意开篇交代句、末尾总结句和常识性语句，提高文章的呼应性。开篇句往往交代得知消息的渠道，并表明求职 心 愿。如：Ive learned from the newspaper that you are employing a.and Im very interested in it.末尾句往往表达希望能很快收到答复的迫切愿望并表明感激之情。如：I would be very thankful if you would give me an early reply.单 元

40、 写 作第二，求职信往往需要介绍自己的姓名、年龄、身高、健康状况、业余爱好、特长、工作态度及人际关系等。常见的短语有be in good health,be good at,be expert in,have rich working experience,enjoy doing sth.，in ones spare time,be strict with,be kind to,get on well with等。此外，要防止遗漏要点。如果是针对广告招聘的求职信，应认真阅读广告，明确招聘要求，并对照自己的条件，逐一加以介绍，同时还要注上自己的通讯地址和联系方式。注意：1.篇幅不宜太长，要简明扼

41、要。2态度要诚恳，实事求是。3所展示的信息要精炼且有针对性。4语气要客气、礼貌。5可用各种时态，通常用一般现在时和一般过去时。常用句型1开头。说明写求职信的缘由与动机。I would like to apply to become a(an).in your company.In todays newspaper I noticed your advertisement for.Im writing this letter to apply for.2正文。介绍个人情况。I graduated from.I am majoring in./My major is.I am experience
