【正文】 語(yǔ)，其邏輯主語(yǔ)必須和句子主語(yǔ)保持一致”的原則，watching的邏輯主語(yǔ)應(yīng)和后面句子主語(yǔ)一致，所以句子主語(yǔ)應(yīng)為“we”，答案為C。例8. [2007 重慶卷] The girl in the snapshot was smiling sweetly, her long hair _________ in the breeze A. was flowing B. flowing C. flowed D. having flowed 解析：本題沒(méi)有連詞，所以后面應(yīng)用非謂語(yǔ)動(dòng)詞，her long hair是非謂語(yǔ)動(dòng)詞的邏輯主語(yǔ)，和非謂語(yǔ)動(dòng)詞構(gòu)成獨(dú)立主格結(jié)構(gòu)。所以答案為B。原則五、不定式做狀語(yǔ)一般有兩種：目的狀語(yǔ)和出乎意料的結(jié)果狀語(yǔ)（表示順其自然的結(jié)果用ing形式）。例9.（04福建） The news reporters hurried to the airport, only _______ the film stars had left.A. to tell B. to be told C. telling D. told解析：本句句意為“記者們匆匆趕到機(jī)場(chǎng)，卻被告知明星們已經(jīng)走了”，表出乎意料的結(jié)果常常用only to do，所以答案為B。例10. The glass doors have taken the place of the wooden ones at the entrance, ________ in the natural light during the day. [2007 天津卷]A. to let B. letting C. let D. having let解析：本題句意為“玻璃門(mén)替換了木頭門(mén)，自然光就進(jìn)來(lái)了”，自然光進(jìn)來(lái)時(shí)順其自然的結(jié)果，所以用doing, 答案為B。例11 . His parents were killed in the accident,(thus )_______ him an orphan.A. leave B. leaving C. left D. to leave 解析：他父母出了事故，他變成了孤兒就是意料之中在事情了，用現(xiàn)在分詞表結(jié)果狀語(yǔ)。 例 12.. I hurried to school, only _______ that it was Sunday. A. find B. finding C. found D. to find解析：發(fā)現(xiàn)是星期天是我匆忙趕到學(xué)校意料之外的結(jié)果，說(shuō)明我忘記了，如果我知道是星期天就不可能還匆忙地趕到學(xué)校了。用不定式表意料之外的的結(jié)果。注意：表示“為了…”，常用不定式作狀語(yǔ)，這時(shí)，狀語(yǔ)動(dòng)詞動(dòng)作發(fā)生時(shí)間與句子謂語(yǔ)動(dòng)作時(shí)間相比，是將來(lái)，例如：例13.（09遼寧卷） , you need to give all you have and try your best.A Being a winner B To be a winner C Be a winner D Having been a winner解析：根據(jù)句意“要想成為獲勝者，你要付出所有，盡最大努力”，此處表目的，所以答案為B。對(duì)比：He sent me an , ________ to get further information.A. hoped B. hoping C. to hope D. hope答案為B. 現(xiàn)在分詞hoping表示與send me an 同時(shí)發(fā)生的動(dòng)作。一些考生認(rèn)為應(yīng)該填不定式作目的狀語(yǔ)。不定式作目的狀語(yǔ)時(shí)，句子的正確形式是：He sent me an to get further ，如果要選擇“hoped”時(shí)，句子的正確形式是：He sent me an and hoped to get further information?！癶ope”和“sent”作并列謂語(yǔ)。比較：1）.He worked deep into the night, preparing(prepare) a speech for the president. 2）. I got up very early this morning to prepare breakfast for my family.原則六、 現(xiàn)在分詞的否定原則是在—ing前加not，有not doing, not having done, not having been done幾種形式。例14.（08浙江卷）______that he was in great danger, Eric walked deeper into the forest.A. Not realized B. Not to realize C. Not realizing D. Not to have realized解析： 本題考查doing的否定形式not doing，答案為 C。原則七：主動(dòng)表示被動(dòng)意義，要用現(xiàn)在分詞作狀語(yǔ)1. 表示感覺(jué)的系動(dòng)詞用主動(dòng)形式表示被動(dòng)意義，如feel(摸起來(lái)) ,sound（聽(tīng)起來(lái)） ,look（看起來(lái)）,taste（味道嘗起來(lái)）,smell（聞起來(lái)）2. 不是強(qiáng)調(diào)被動(dòng)動(dòng)作，而是表示動(dòng)作的性質(zhì)和特征的用法，后面帶有well ,easily,smoothly 等。例如。The book sells well.The door opens easily. tired and weak, the woman should have a day off to see a doctor.A. Look B. Looking C. Looked D. Looking 看起來(lái)又累又虛弱，這個(gè)婦女應(yīng)該休一天假去看醫(yī)生。 （look在本題中不是實(shí)意動(dòng)詞，而是感觀系動(dòng)詞，系動(dòng)詞在非謂語(yǔ)中用主動(dòng)式表被動(dòng)。） smoothly, this kind of pen sells well in our school.A. To write B. Writing C. being written D. Written 因?yàn)閷?xiě)起來(lái)很流暢，這種鋼筆在我們學(xué)校很暢銷。 解析：動(dòng)詞如果不是表示動(dòng)作，而是表示物體具有某種性質(zhì)或特征時(shí)，往往用主動(dòng)形式表示被動(dòng)。原則八：演變成了介詞或連詞的分詞。英語(yǔ)中有些詞表面上看是分詞，但實(shí)際上已經(jīng)變成了介詞，因此應(yīng)該用ing形式還是分詞ed形式已經(jīng)變得約定俗成了。這時(shí)往往不適用非謂動(dòng)詞規(guī)則，而是看英美人士的習(xí)慣。例17．___________her age，she looks quite young．A．Consider B. Considered C. To consider D. Considering｛解析：題意是：“就她的年齡而論，她顯得十分年輕?！边@里的considering表示“考慮到；鑒于”，它已經(jīng)變成了介詞，不管是“考慮還是被考慮”這里都用considering。｝高中階段我們還學(xué)過(guò)的有：介詞concerning關(guān)于 regarding關(guān)于，given鑒于 supposing假如 原則九：當(dāng)主從句主語(yǔ)一致，且從句中包涵系動(dòng)詞be時(shí)，主語(yǔ)和be 應(yīng)同時(shí)省略。即連詞+doing/done 例18 If _________ another hour, I would have finished it better.(give的恰當(dāng)形式填空)。例 19. While _________ homework, the boy likes listening to light music.(do的恰當(dāng)形式填空)解析：18. given 是由if I was given another hour省略來(lái)的，if 在省略前省略后都是連詞； 是由while the boy are doing homework省略來(lái)的，while在省略前后都是連詞｝注意：before和after可以做介詞，后面接動(dòng)名詞例201） After __________ , he found a job as a secretary in a pany.(graduate的恰當(dāng)形式填空)2）Before_________ a proper person to be the new president, the old president wouldn’t resign.(select的恰當(dāng)形式填空)解析： graduating/graduation after 這時(shí)是個(gè)介詞，所以后面總是用動(dòng)名詞，如果改為after he graduated，那么這個(gè)after就變成了連詞。2題中的before用法與after 一樣，后面加句子時(shí)，是連詞，后面只加一個(gè)動(dòng)詞時(shí)，要用動(dòng)名詞形式，并充當(dāng)介詞。所以2題填selecting｝
