八年级英语上册unit9习题单元语法小专题

1、单元语法小专题(Grammar Focus)语法精讲情态动词can的用法1can是情态动词，没有人称和数的变化，但有时态的变化，它的过去式为could，其后可直接接动词原形，其用法如下：(1)表示能力，意为“能，会”。如：Can you swim？你会游泳吗？Can you answer the question？你能回答这个问题吗？(2)表示许可，意为“可以”，相当于may(比may更口语化，may较正式)。此外，could也可以表示许可，语气更加委婉。如：Can/May I come in？我可以进来吗？Can you help me？你能帮我吗？You may go home now.你

2、现在可以回家了。Could you help me find it？你能帮我找到它吗？(3)用于提出邀请。对其作肯定回答通常用“Sure./Of course./Certainly./Yes，I'd love (like) to.”等，作否定回答通常用“Sorry/No，I can't.”等。如：Can he come to my party？他能来参加我的宴会吗？Yes.He'd love to.是的。他很乐意。Can you go to the baseball game？你能去看棒球比赛吗？Sorry，I can't.对不起，我不能。(4)用于否定句或疑问

3、句中，表示推测。如：Mr.Wang can't be at home.王老师不可能在家里。2can句式变化(1)在变否定句时，直接在后面加上“not”，写作can't或cannot。如：I can speak French.我会讲法语。I can't speak French.我不会讲法语。(2)在变一般疑问句时，can直接移到主语前(原主语的首字母改成小写，第一人称应变为第二人称)即可。如：I can play the piano.我会弹钢琴。Can you play the piano？你会弹钢琴吗？其肯定回答可用yes，OK或certainly等；否定回答可用no

4、或sorry等。如：Can you look after my books，please？你能照看一下我的书吗？OK.可以。用certainly回答语气更为肯定。如：Can I see your guitar？我能看看你的吉他吗？Certainly.当然可以。语法精练.单项选择。( )1.Lisa，_ you speak French?Yes，but only a little.Aneed Bmust Cmay Dcan( )2.Could I look at your picture?Yes，of course you _.Acould Bcan Cwill Dmight( )3.Can y
