1、Unit 4Why dont you talk to your parents?第三課時(Grammar Focus4c)單元同步語法精講精練浙江地區(qū)情態(tài)動詞should，could的用法“should動詞原形”表示“應(yīng)該/應(yīng)當(dāng)做某事”?！癱ould動詞原形”表示“可以做某事”。should和could都可用來提出建議，表示輕微的批評或遺憾，但could語氣更委婉、客氣。should意為“應(yīng)當(dāng)/應(yīng)該”；could意為“可以/可能”。eg：You shouldnt argue with your parents!你不應(yīng)該和你父母爭吵！You could be more careful.你可以更仔

2、細(xì)些。當(dāng)征求別人意見時，常用should。eg：What should I do？我該做什么？連詞although，so that，until的用法although意為“盡管/雖然”，相當(dāng)于though，用來引導(dǎo)讓步狀語從句。句中用了although或though，就不可再用but。若要強(qiáng)調(diào)前后兩部分的對比意義，可在主句前加yet或still。eg：Although/Though he has a lot of money，yet/still he is unhappy.他雖然有很多錢，但并不幸福。so that意為“目的是/為的是/以便”，引導(dǎo)目的狀語從句，從句中通常含情態(tài)動詞can，may

3、，might等。eg：He got up very early so that he could catch the early bus.他起床很早，為的是能趕上早班公共汽車?！就卣埂縮o that引導(dǎo)的目的狀語從句可與in order that或in order to結(jié)構(gòu)相互轉(zhuǎn)換。until與延續(xù)性動詞連用時，動詞用肯定形式，表示“直到為止”，指主句的動作一直持續(xù)到until后的動作發(fā)生為止；與短暫性動詞連用時，動詞須用否定形式，意為“直到才”，指主句的動作一直到until后的動作發(fā)生時才發(fā)生。eg：I waited until 3：00，but he didnt come.我一直等到3點(diǎn)，

4、但他沒來。(wait為延續(xù)性動詞)The noise of the street didnt stop until midnight.街上的喧鬧聲一直到半夜才停止。(stop為短暫性動詞) 一、單項(xiàng)選擇。1Last year I _ drive.I used to take the bus.AcouldBcouldntCshouldDshouldnt2_ I try on those shoes in the window?_.They are just on show.ACould；Yes，you can BCan；Sorry，you couldntCCould；Sorry，you cant
