八年级英语上册 第27期课件 牛津深圳版.ppt

第27期,语法运用 Grammar in use一、should1.should在肯定句中可用来讨论义务和职责或提出建议,意为“应该”,例如:You should pay attention to your spoken English.你应该注意你的英语口语。,2.should后面跟不带to的动词不定式。否定式为should not,其缩略形式是shouldnt,意为“不应该”,例如:You should not/shouldnt play football on the road.你不应该在马路上踢足球。,3.should用于疑问句,表示征求意见或请求指示,例如:-Should I play computer games now?-我现在可以玩电脑游戏吗?-Yes,you should./No,you shouldnt.-是,你可以。/不,你不可以。,4.should和ought to都可以用来谈论义务和职责或提出建议。两者可以互换使用,不过should比较常用,例如:You should take your fathers advice.=You ought to take your fathers advice.你应该听取你父亲的意见。,5.should还有一种用法,表示:更正别人的说法。例如:-The total number of these trees is 234.-这些树的总数是234.-No,that should be 235.Please check it again-不,应该是235。请再检查一遍。,【语法笔记】must,should和ought to的区别:1.must的意思与should和ought to类似,但语气更强或更肯定,表示“必须”之意,含有命令的性质;should和ought to语气则更缓和。例如:You must give up smoking!你必须戒烟!You should/ought to give up smoking.你应该戒烟。,2.should可以替代must使指示听起来更客气些。例如:You should tell the police what happened just now.你应该告诉警察刚才发生了什么。,3.should和ought to可以用来预测,表示预期会发生什么事情。must往往不这样用。例如:()It should be rainy next Monday.下周一会下雨。()It must be rainy next Monday.,二、had betterhad better用来表示竭力劝告,或告诉人们(包括自己)该做什么事,意为“做是好的;最好还是”。看下面用法:1.had better没有人称和时态的变化,其后跟不带to的动词不定式,即had better do;其缩略形式为 d better。例如:Now we had better listen to her.我们现在最好听她说。,2.“had better not+不带to的动词不定式”表示否定。例如:You had better not go to Japan next week.你下周最好不要去日本。3.had better 用于回答时,通常用缩略形式。例如:-Shall I go to clean the classroom now?-我现在去打扫教室好吗?-Youd better./Youd better not.-你最好去打扫。/你最好不要去打扫。,【语法笔记】1.had better通常并不表示所提出的建议比其他选择更好这里没有比较的意思。2.用于谈论最近的将来,比should或ought to在时间上更为紧急。例如:Its going to rain.We had better hurry up.马上下雨了。我们还是快点吧。,实战演练I.根据句意,用should 或 shouldnt及括号中的单词完成下面句子。1.You _(water)the flowers
