Unit 1Whats the matter?第三課時(Grammar Focus4c)單元同步語法精講精練 概念及組成反身代詞是一種表示反射或強調(diào)的代詞。它是由第一人稱、第二人稱形容詞性物主代詞或第三人稱代詞賓格形式，加詞尾self或selves組成。 用法反射用法這種用法通常表示反身代詞與句中的主語是同一人。它在句中作賓語，不能省略，否則該句是一個結(jié)構(gòu)不完整的錯句。eg：Jane is too young to look after herself.簡年紀(jì)太小，以至于不能照顧自己。I teach myself English.我自學(xué)英語。 強調(diào)用法反身代詞在強調(diào)用法中表示強調(diào)，即用來加強某個名詞或者代詞的語氣，可譯為“親自；本人”。此時，它在句中作同位語，即使去掉，也不影響句子的完整性。eg：I myself did the homework last night.昨晚是我自己做的家庭作業(yè)。(作主語同位語，可緊跟主語之后，也可置于句末)You can go and ask John himself.你可以去問約翰本人。(作賓語同位語，緊跟在賓語之后) 【拓展】含反身代詞的常見短語：learn sth.by oneself自學(xué)enjoy oneself玩得開心help oneself to隨便吃leave sb.by oneself把某人單獨留下improve oneself提高自己look after oneself照顧自己 should情態(tài)動詞，意為“應(yīng)該，應(yīng)當(dāng)”，可用于各種人稱，無人稱和數(shù)的變化，也不能單獨作謂語，只能和動詞原形連用。其否定形式為shouldnt。變一般疑問句時， should應(yīng)提到主語之前。其用法如下：表示責(zé)任和義務(wù)、勸告和提出建議時。eg：We should study hard.我們應(yīng)該努力學(xué)習(xí)。You should drink lots of water.你應(yīng)該喝大量的水。表示命令和要求時，語氣比較強烈。eg：You shouldnt be so careless.你不應(yīng)該這么粗心。表示預(yù)測和可能性。eg：He should be a teacher.他應(yīng)該是一名老師。 一、根據(jù)句意，用括號中所給單詞的適當(dāng)形式填空。1 I have a sore throat.I think you should _ (go) to a doctor now.2 They finished their homework by _ (they)3 Jim enjoyed _(him) in the park yesterday afternoon.4 Help _(your) to some beef， boys.5 She hurt _(her) playing volleyball yesterday afternoon.go themselveshimselfyourselvesherself 二、句型轉(zhuǎn)換。6 I should put some sugar into the tea.(改為否定句)I _ any sugar into the tea.7 Should I visit him this weekend？(作否定回答)No， _8 She should buy_a_new_TV.(對畫線部分提問)_ she_?9 Linda should exercise every day to keep healthy.(改為一般疑問句)_ every day to keep healthy?10 You should get to the zoo at_9：00_am.(對畫線部分提問)_ we get to the park?shouldnt put you shouldntWhat should doShould Linda exercise When should 三、根據(jù)漢語意思完成下列句子翻譯。11我們應(yīng)該相互學(xué)習(xí)。We _ from each other.12蘇珊不應(yīng)該看太長時間的電視。Susan _ TV too long.13 我應(yīng)該早點上床睡覺嗎？是的，你應(yīng)該。_ to bed early?Yes， you _14相信自己，你一定能做好的。Believe _You can do it well.should learn shouldnt watch Should I go shouldin yourself 15我認(rèn)為我能照顧好我自己。I think I can _ well.look after myself
