分析 本文講述的是環(huán)境污染的問(wèn)題.
科學(xué)家們到鄉(xiāng)村看到嚴(yán)重的污染,從空氣到河流都被嚴(yán)重的污染了.他們說(shuō)服政府通過(guò)了保護(hù)環(huán)境的法律,保持大自然的平衡.現(xiàn)在一切都改變了,鳥(niǎo)兒在歌詞,樹(shù)木和花草在生長(zhǎng).
解答 A group of scientists were planning to go to∧countryside to do a scientific research in order to find out that whether the environment of the country had∧polluted.On arrival,they started to check the air and water.To our surprise,they found how terribly the situation was.They couldn't see the serious pollution.Look into the cause,they persuade the government to pass the law to protect environment and kept the balance of nature.Now everything has changed.Birds are singing while tree and grass are waving.
解析:
1.countryside 前加the.考查冠詞.表示"鄉(xiāng)下"用the countryside.
2.去掉that.考查賓語(yǔ)從句的引導(dǎo)詞.whether 引導(dǎo)賓語(yǔ)從句the environment of the country had polluted
表示"是否環(huán)境已經(jīng)被污染",所以去掉that.
3.polluted前加been.考查被動(dòng).主語(yǔ)the environment of the country 和謂語(yǔ)動(dòng)詞polluted 之間是被動(dòng)關(guān)系,所以polluted前加been.
4.our改為their.考查代詞. 和上句的主語(yǔ)they呼應(yīng)用their.
5.terribly改為terrible.考查形容詞.做the situation was的表語(yǔ)用形容詞terrible,表示"他們知道情況使多么惡劣".
6.couldn't 改為could.考查邏輯關(guān)系.根據(jù)上句表示"他們知道情況使多么惡劣",可知本句表示"他們能夠看到嚴(yán)重的污染",所以應(yīng)該是肯定句,couldn't 改為could.
7. Look改為 Looking.考查非謂語(yǔ)動(dòng)詞.Look into the cause做伴隨狀語(yǔ),和主語(yǔ)they 之間是主動(dòng)關(guān)系,所以用現(xiàn)在分詞 Looking.
8. persuade 改為persuaded.考查謂語(yǔ)動(dòng)詞的時(shí)態(tài).本句講述的是過(guò)去的事,所以謂語(yǔ)動(dòng)詞用過(guò)去式persuaded.
9.kept改為keep. 考查并列一致關(guān)系.和to pass the law to protect environment 并列,做目的狀語(yǔ),因詞用kept 的原形keep.
10.tree改為trees.考查名詞.tree是可數(shù)名詞,本句表示"樹(shù)木"所以用復(fù)數(shù)trees.
點(diǎn)評(píng) 考查短文改錯(cuò).
被動(dòng)語(yǔ)態(tài)的基本時(shí)態(tài)變化
被動(dòng)語(yǔ)態(tài)由"be+及物動(dòng)詞的過(guò)去分詞"構(gòu)成,be隨時(shí)態(tài)的變化而變化.以do為例,各種時(shí)態(tài)的被動(dòng)語(yǔ)態(tài)形式為:
1)am/is/are+done (過(guò)去分詞) 一般現(xiàn)在時(shí)
Visitors are requested not to touch the exhibits.
2)was/were done 一般過(guò)去時(shí)
I was given ten minutes to decide whether I should reject the offer.
進(jìn)行時(shí)態(tài)的被動(dòng)語(yǔ)態(tài)加being
3)am/is/are being done 現(xiàn)在進(jìn)行時(shí)
A new cinema is being built here.
4)was/were being done 過(guò)去進(jìn)行時(shí)
A meeting was being held when I was there.
完成時(shí)的被動(dòng)語(yǔ)態(tài)加been
5)has/have been done 現(xiàn)在完成時(shí)
All the preparations for the task have been completed,and we're ready to start.
6)had been done 過(guò)去完成時(shí)
By the end of last year,another new gymnasium had been completed in Beijing.
