(He walked down the hill and sang softly to himself.) 他從山上走下來(lái)，一路哼著小曲兒。 注：如果動(dòng)詞-ing形式所表示的動(dòng)作與謂語(yǔ)動(dòng)作同時(shí)存在或同時(shí)發(fā)生，則用一般式(即doing)；如果動(dòng)詞-ing形式所表示的動(dòng)作發(fā)生在謂語(yǔ)動(dòng)作之前則用完成式(即having done)。 動(dòng)詞的非謂語(yǔ)形式是歷年高考命題的熱點(diǎn)，而在句中作狀語(yǔ)的 V-ing 形式則是英語(yǔ)高考考點(diǎn)的重中之重?，F(xiàn)筆者就 V-ing 形式作狀語(yǔ)幫助同學(xué)們作個(gè)小結(jié)。 ????V-ing 形式在句中修飾主句的謂語(yǔ)動(dòng)詞，說(shuō)明句中謂語(yǔ)動(dòng)詞所處的狀態(tài)，它是主句主語(yǔ)動(dòng)作的一部分。與主句謂語(yǔ)表示的動(dòng)作幾乎是同時(shí)發(fā)生的，可以表示時(shí)間、原因、伴隨、結(jié)果等。 ????值得一提的是：當(dāng)從句中的謂語(yǔ)動(dòng)詞所表示的動(dòng)作發(fā)生在主句的謂語(yǔ)動(dòng)詞所表示的動(dòng)作之前，則應(yīng)用其完成式的 V-ing 短語(yǔ) having （ been ） done 。 一 . V-ing 形式表示時(shí)間 1. _______________ such heavy pollution already, it may now be too late to clear up the river. A. Having suffered B. Suffering C. To suffer D. Suffered 析：句意為“當(dāng)河流受到嚴(yán)重污染時(shí)，現(xiàn)在要清理它已經(jīng)為時(shí)過(guò)晚了”。很明顯，“污染”在前，“清理河流”在后，應(yīng)用 suffer 的完成式，故選 A 項(xiàng)。 2. ___________________a reply, he decided to wait again. A. No receiving B. Receiving not C. Not having received D. Having not received 析：在 V-ing 形式的否定式中，否定詞（ no 、 not 或 never ）應(yīng)置于其前面，不能置于其后面，因此 B 、 D 項(xiàng)不能選，從句意來(lái)看，“未收到答案”在前，“決心等待”在后。故選 C 項(xiàng)。 二 . V-ing 形式表示原因 3. ______________ anything about the accident, he went to work as usual. A. Not known B. Known not C. Known not D.

A. angrily pointing B. and point angrily C. angrily pointed D. and angrily point 析： A 項(xiàng)為正確答案，根據(jù)語(yǔ)法知識(shí) B 、 C 、 D 三項(xiàng)都不能選。 四 . V-ing 形式表示結(jié)果 6. European football is played in 80 countries _____________ it the most popular sport in the world. A. making B. makes C. made D. to make 析： making it …其形式相當(dāng)于定語(yǔ)從句 which makes it the most popular sport in the world 的簡(jiǎn)化形式。故 A 項(xiàng)為正確答案。 【練習(xí)】 Ⅰ. 選出可以填入空白處的最佳選項(xiàng)。 1. ______ many times, he finally understood it.

The place was totally uncared for，quite 1 and overgrown with all sorts of useless things. I 2 my way through bushes and tall weeds to the front door and rang the bell. I was glad that I had found him. In twenty minutes he 3 me right on all the 4 that had puzzled me. I was on the 5 of leaving when I looked out of his study window and said，“You’re very fond of gardening，I see.” “No，I’m not，” he said.“ 6 ，I love this garden，though. It’s 7 I always wanted it to be. I never touch it at all.” “It could be made lovely. It 8 a pity to let all this ground go to waste. But perhaps you don’t 9 that way?” said I “I don’t. I lived here when I was a child，and I had 10 of gardening then. It was my father’s hobby，you see. Unfortunately，he wasn’t 11 enough to do it himself. My brother and I did all of it between us year after year. There was one right way and many wrong ways. Each blade（葉片） of grass was an enemy to be 12 by hand, not just cut off. I’ve spent a good part of life at work here.” “I see. You took a dislike to it, and now you’re getting even！” “I dislike it. Then, of course, I didn’t understand the 13 it had. It used to 14 me. It appeared in my dreams—a mistake here, something not quite straight here, the enemy showing its head in a place I was 15 to have cleaned. The work was too much. It seemed endless. The size of the place was itself a fight to a boy.” “And now it’s yours，you’re just letting it go to... ” “ 16 ?” he said.“No，I don’t agree with that. This garden and I are now the best friends. I like 17 it grow 18 its own way. I make no demands on it. I never disturb it, and it never disturbs me. It has 19 at last, and so have I.” “But the path is over grown. It’s inconvenient for you，isn’t it?” “That’s part of my 20 ，” he laughed.“You can go out the back way. The weeds are shorter there because they don’t get the sun.” 1.

Hang-gliding (懸掛式滑翔) in Rio De Janeiro According to the hang-gliders of Rio, once you've swooped (俯沖) over the city's streets, gazing at the Sugar Loaf, and the city of Niteroion, the other side of Guanabara Bay, you will understand why birds are peaceful animals.
