29、 deaf mans ear drum作后置定語，修飾straw；the other to a piece of smoked glass是個省略句，可補充為the other end of the straw joined to a piece of smoked glass。知識拓展 并列句中的省略常有以下幾種情況：如果主語不同，而謂語動詞中的一部分相同，則省略謂語動詞中相同的那部分。John must have been playing football and Mary(must have been)doing her homework 約翰一定在踢球，而瑪麗一定在做作業(yè)。主語相同，謂

30、語動詞也相同，則二者都可以省略。His suggestions made John happy，but(his suggestions made)Mary angry 他的建議使約翰高興，卻使瑪麗很生氣。主語相同，而謂語不同，則可以省略主語。Old McDonald gave up smoking for a while，but(he)soon returned to his old ways 老邁克唐納戒了一陣子煙，可很快又抽上了。在并列復(fù)合句中，如果that從句從屬于第二個并列句且它的謂語動詞和賓語等其他一些成分與第一個并列句相同時，這個that從句通?？梢允÷赃@些相同的部分。Jack w

32、 worth considering what makes“convenience”foods so popular，and _(introduce)better ones of your own 答案：introducing句意：什么東西使得“方便”食品如此流行值得考慮，引進(jìn)你自己的更好的(方便食品)也值得考慮。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

33、solve 但是他發(fā)現(xiàn)這個問題很難解決。findn(賓語)adj(賓補)to do(to do作狀語修飾adj)是finditadj(賓補)to do sth(it是形式賓語，to do sth是真正的賓語)的變式 注意：“to do”形式中當(dāng)“do”為不及物動詞時，應(yīng)在后面加上適當(dāng)?shù)慕樵~。并且動詞不定式使用一般式。The man found the river dangerous to swim inThe man found it dangerous to swim in the river 這個人發(fā)現(xiàn)在這條河里游泳很危險。知識拓展 find后的賓語可以是名詞或代詞，而補語則可由許多成分充

34、當(dāng)：(1)find賓語形容詞/副詞/介詞短語。如：I seldom found him out 我很少發(fā)現(xiàn)他外出。When I woke up I found myself in a hospital 當(dāng)我醒來時，我發(fā)現(xiàn)自己在醫(yī)院里。(2)find賓語現(xiàn)在分詞。如：They found the lost boy hiding in the cave 他們發(fā)現(xiàn)那個失蹤的男孩藏在洞里。(3)find賓語過去分詞。如：We found the place outside greatly changed 我們發(fā)現(xiàn)外面全變了。(4)find賓語名詞。如：I find him an easy man to

35、 work with 我覺得他是個容易共事的人。活學(xué)活用 用恰當(dāng)形式填空(1)I found him easy _(get along)答案：to get along with句意：我發(fā)現(xiàn)他很容易相處。本題屬于findn(賓語)adj(賓補)to do結(jié)構(gòu)，在此結(jié)構(gòu)中要求to do使用一般式，并且當(dāng)do為不及物動詞時，應(yīng)加上適當(dāng)?shù)慕樵~。(2)I like getting up very early in summerThe morning air is so good_(breathe)答案：to breathe句意：在夏季，我喜歡早起。呼吸早晨的空氣有益于身心。本句還可以轉(zhuǎn)換為：It is

36、so good(for us)to breathe the morning air不定式(短語)修飾作表語或補足語的形容詞時，通常采用主動形式表示被動含義。(3)They found the lecture hard_(understand)；they all felt sleepy 答案：to understand句意：他們發(fā)現(xiàn)這個講座很難懂，所以他們都有懨懨欲睡的感覺。不定式修飾作表語或補足語的形容詞時，如果和句子的主語之間構(gòu)成邏輯上的動賓關(guān)系，不定式通常采用主動形式表示被動含義。如何寫求職信(Letter of application)寫作指導(dǎo) 求職信屬于應(yīng)用文中的書信類。寫作時，要注意

37、書信的一些基本格式。首先，要注意開篇交代句、末尾總結(jié)句和常識性語句，提高文章的呼應(yīng)性。開篇句往往交代得知消息的渠道，并表明求職心愿。如：Ive learned from the newspaper that you are employing a.and Im very interested in it末尾句往往表達(dá)希望能很快收到答復(fù)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 第二，求職信往往需要介紹自己的姓名、年齡、身高、健康狀況、業(yè)余愛好、特長、工作態(tài)度及人際關(guān)系等。常見的短語有be
