【教学重难点】
使学生能够了解并掌握现在分词和过去分词作宾语补足语的用法,并在真实语境中灵活运用。
【教学过程】
Step 1 课前自学
一、知识梳理
Activity 1
1. Look at the sentences from the reading passage and answer the questions.
a We see a woman swimming at night in a dark sea. b It made people frightened of sharks,...
(1) In sentence (a), who is swimming at night
(Answer: In sentence (a), a woman is swimming at night.)
(2) In sentence (b), who is frightened of sharks
(Answer: In sentence (b), people are frightened of sharks.)
(3) Why does the author choose to use different forms of verbs in the two sentences
(Answer: In sentence (a), a woman is swimming. In other words, the woman does the action of swimming. So the author uses -ing. But in sentence (b), people are frightened. As a result, passive voice is used. So the author uses -ed.)
2. Now get the Ss to look for more sentences with these structures in the reading passage.
二、主要用法精讲
现在分词作宾语补足语
1)see, watch, hear, feel, notice等感官动词后接现在分词作宾语补足语,表示该动作正在进行。例如:
a. I saw him running down the street.(我看见他正沿着街跑。)
b. I felt an ant climbing over my leg.(我感到一只蚂蚁正在我的腿上爬。)
2) have, leave, keep等使役动词后接现在分词作宾语补足语,表示“使处于某种状态”。例如:
a. They shut the door and left, leaving the fire burning.(他们关上门走了,留下火在燃烧。)
b. Sorry, I’ve kept you waiting a long time.(对不起,让您久等了。)
过去分词作宾语补足语
1)like, want, wish, order等后接过去分词作宾语补足语,表示命令或希望某件事被完成。例如:
I want the room cleaned up when I come back.(我希望在我回来的时候,房间已清理好。)
2)see, hear, notice, observe, watch, feel, find等感官动词后接过去分词作宾语补足语,表示该动作与宾语之间是被动关系或者该动作已经完成。例如:
a. I saw an old man knocked down by a car just now.(我刚才看到一位老人被车撞倒了。)
b. He found his home town greatly changed.(他发现自己的家乡大变样了。)
3)have, get, make, leave, keep等使役动词后接过去分词作宾语补足语,表示动作由他人完成。例如:He had his money stolen.(他的钱被偷了。)
Step 2 语法探究
1.“感官动词+宾语+doing”,动词-ing形式作宾补强调动作的延续性,表示动作正在进行。
2.“感官动词+宾语+done”(动词-ed形式作宾补,表示被动)
3.使役动词“have/has+宾语+doing”(动词-ing形式作宾补,表示主动)
4.使役动词“have/got+宾语+done”(动词-ed形式作宾补,表示被动)
5.“find+宾语+done”,“发现……被……”,动词-ed形式表被动。
6.“leave+宾语+doing”,“让、听任……保持”,动词-ing形式表主动。
7.“with/without+宾语+done”,“随着…….被……”动词-ed形式表被动。
