I have to help my mother do some cleaning. A. So am IB. So I amC. Neither am ID. Neither I am【解析】本題考查倒裝句的用法。原句是否定句,so開(kāi)頭的倒裝句用于肯定句,所以排除A、B兩項(xiàng)。又因?yàn)榈寡b句要用倒裝語(yǔ)序?！敬鸢浮?CSection B1.You took part in some volunteers during the summer holiday, didnt you? 你暑假參加了一些志愿活動(dòng)，是嗎？ take part in 表示積極主動(dòng)地“參加”某項(xiàng)活動(dòng)。join 則表示“參加”某個(gè)黨派、組織等。有時(shí)join后面還可跟人 構(gòu)成join sb in doing sth，表示“加入某人當(dāng)中去一起做某事”。 They _ the sports meet last week. 他們上周參加了運(yùn)動(dòng)會(huì)。 He _ an English club during the summer holidays. 暑假期間他加入了一個(gè)英語(yǔ)俱樂(lè)部。 Please _ us _ _. 請(qǐng)加入我們一起游泳吧。 這是一個(gè)反意疑問(wèn)句。反意疑問(wèn)句的構(gòu)成一般是遵循“前句肯定，問(wèn)句否定”、“前句否定，問(wèn)句肯定”的原則。如： He likes watching TV, _? 他喜歡看電視，對(duì)嗎？ They didnt finish their homework last night, _? 他們昨天晚上沒(méi)有完成作業(yè)，是嗎？ There is little water in the bottle, _? 瓶子沒(méi)有什么水了，是嗎？ Lets go to school, _ _? 咱們上學(xué)去，好嗎？ Please open the door, _ _? 請(qǐng)打開(kāi)門，好嗎？ Dont make much noise, _ _? 不要大吵了，好嗎？2. What a wonderful experience! 多么精彩的體驗(yàn)啊！ How interesting！真有趣！ 這是由what和how引導(dǎo)的感嘆句，其中主語(yǔ)和謂語(yǔ)已經(jīng)省略。由what 引導(dǎo)的感嘆句一般構(gòu)成為：What + a/an + 形容詞+ 單數(shù)可數(shù)名詞 + 主語(yǔ) + 謂語(yǔ)！What + 形容詞 + 可數(shù)名詞復(fù)數(shù)/不可數(shù)名詞 + 主語(yǔ) + 謂語(yǔ)！ 由how引導(dǎo)的感嘆句一般構(gòu)成為： How + 形容詞/副詞 + 主語(yǔ) + 謂語(yǔ)！ How + 主語(yǔ) + 謂語(yǔ)！ How + 形容詞 + a/an + 名詞 + 主語(yǔ) + 謂語(yǔ)! _ kind girl she is! 她是一個(gè)多么善良的女孩啊！ _ fast he is running! 他跑得真快！ _ I love you! 我很愛(ài)你！ _ fine weather we have today! 我們今天的天氣真好！ _ kind the girl is! 這個(gè)女孩真善良！ _ beautiful _ flower she has! 她有一朵很美的花！3.

Though I had no time to travel, I still felt very happy. 盡管我沒(méi)有時(shí)間履行，我仍然感覺(jué)幸福。 though表示“雖然；盡管”，與although同義，引導(dǎo)讓步狀語(yǔ)從句。如： _ he was ill, he still kept on working till five oclock this afternoon. 盡管他病了，但仍然連續(xù)工作到了下午五點(diǎn)。 _ he is in poor health, he works hard. 盡管他身體不好，他努力工作。 He failed in the exam _ he worked hard. 盡管他努力學(xué)習(xí)了，但是他考試還是失敗了。5.

To help others makes us happy. 幫助別人讓我們感覺(jué)幸福。 這里謂語(yǔ)動(dòng)詞是makes，主語(yǔ)則是不定式to help others。當(dāng)主語(yǔ)是不定式時(shí)，還可用形式主語(yǔ)it代替不定式，將真正的主語(yǔ)不定式放在句尾，構(gòu)成：_ _ us happy _. “make + 名詞 + 形容詞”，表示“使某人怎么樣”。如： What has _ you so _? 是什么讓你這么生氣？Section C1、She has seen the changes in Beijing herself. 她親眼目睹了北京的變化。See sth oneself 親眼目睹2、Big families were crowed into small houses.crowd - 擁擠, 擠,聚集(動(dòng)詞)；人群，群眾；一群(名詞) crowded - 擁擠的(形容詞)3、Few children had the chance to receive a good education.few后接可數(shù)名詞, 而little后接不可數(shù)名詞,兩者都表示否定含義 a few, a little兩者都表示肯定含義.4、People kept in touch with their friends and relatives far away mainly by letter or telegram.keep in touch with 與.保持聯(lián)系 get in touch with 與.取得聯(lián)系 lose touch with 與.失去聯(lián)系far away 遠(yuǎn)方，遠(yuǎn) far away from 與.離得遠(yuǎn) 5、China has developed rapidly since the reform and opening-up.since - 從以來(lái) （介詞+連詞），是使用現(xiàn)在完成時(shí)的標(biāo)志詞，上面句子中的since是_詞since 后面的時(shí)間短語(yǔ)是過(guò)去的時(shí)間，后面的句子要使用過(guò)去時(shí)develop 動(dòng)詞,發(fā)展 developed 形容詞，發(fā)達(dá)的 developing 形容詞，發(fā)展中的6、There are more kinds of food and clothes to satisfy peoples needs.satisfy 動(dòng)詞，使?jié)M足，使?jié)M意 be satisfied with =be pleased with 對(duì).感到滿意to satisfy peoples needs在句中做后置定語(yǔ)7、Beijing has made rapid progress and it has already succeeded in hosting the 2008 Olympic Games.make progress 取得進(jìn)步 make rapid progress=make progress rapidly 取得快速進(jìn)展make progress with sth 在某方面取得進(jìn)步 make progress (in) doing sth 做某事取得進(jìn)步Section D1、People like to do to relax and enjoy themselves 是定語(yǔ)從句，修飾things,翻譯時(shí)應(yīng)放在前面。 relax 動(dòng)詞，放松 relaxed 形容詞，放松的enjoy oneself 玩得開(kāi)心，自?shī)首詷?lè)enjoy doing sth 2、Chinese people have had more time to spend on various kinds of leisure activities. have time to do sth 有時(shí)間做某事 have a . time (in) doing sth 做某事開(kāi)心/傷心spend 時(shí)間/金錢 on sth / (in) doing sth 花費(fèi)時(shí)間/金錢在某方面/做某事pay 金錢 for sth 為某物付了多少錢 物 cost sb 金錢 某物花費(fèi)某人多少錢 It costs/cost sb 金錢 to do sth 做某事花了某人多少錢 It takes/took sb 時(shí)間 to do sth 做某事花了某人多少時(shí)間3、Many people stay at home having a rest, reading books and watching TV.having a rest, reading books and watching TV 做伴隨狀語(yǔ)，表示同stay at home同時(shí)發(fā)生4、They go to visit some places of interest, and some people even make a tour abroad to see the world.places of interest 名勝古跡 interest 名詞，興趣 interesting 有趣的 interested 感興趣的 be interested in sth / doing 對(duì).感興趣 have / show interest in sth/ doing 有/展示出在某方面/做某事的興趣a tour abroad 出國(guó)旅行 home and abroad 國(guó)內(nèi)外【當(dāng)堂小測(cè)】Section A練習(xí)題一、用have/has gone to; have/has been to; have/has been in填空 1.Where _ she _?
