一、提建议的常用表达方式
提建议是英语中常用的一种交谈方式。一个好的建议或能使人茅塞顿开,或能使人受益匪浅。提建议的常用句型概括起来可分为肯定句形式和疑问句形式两种。
1.肯定句
(1)“主语+should (not)+动词原形+其他”,意为“……(不)应该……”。
e.g.You should call him up right away.你应该立刻给他打个电话。[来源:学科网]
(2)“主语+could+动词原形+其他”,意为“……可以……”,表示委婉地建议别人去做某事,此时语气比should委婉。
e.g.You could call up your teachers and tell them your opinion.你可以给你的老师们打电话,并告诉他们你的看法。
(3)“Let's+动词原形+其他”,意为“让我们……吧”。有时为了使语气显得委婉,可在句末加shall we。
e.g.Let's go to the restaurant for dinner,shall we?我们去饭店吃晚饭好吗?
(4)“You'd better(not)+动词原形+其他”,意为“你最好(不要)做某事”。
e.g.You'd better not make friends with him.你最好不要和他交朋友。
2.疑问句
(1)“Why not/Why don't you+动词原形?”,意为“为什么不……呢?”。
e.g.Why not/Why don't you stay at home?为什么不待在家里呢?
(2)“What/How about+v.ing形式/名词/代词?”,意为“……怎么样?”。
e.g.How/What about going to the movies with me tomorrow morning?明天上午和我一起去看电影怎么样?
(3)“Would you like to+动词原形+其他?”,意为“你愿意……吗?”。
e.g.Would you like to go swimming this afternoon?今天下午你愿意去游泳吗?[来源:学科网ZXXK]
(4)“Would you mind (not)+v.ing+其他?”,意为“你介意(不)做某事吗?”。
e.g.Would you mind going to the farm together?一起去农场你介意吗?
二、连词until,so that和although的用法
1.until常见用法有以下两种情况:如果主句的谓语动词是持续性动词(如live,stay,work,read,study,write,watch,talk,run,walk,sing等)时,则一般用其肯定形式与until连用,表示这个动作或状态一直持续到until后所接的时间到来为止。如果主句的谓语动词是终止性动词(如go,come,leave,begin,start,open,close,find,see等)时,则一般用其否定形式与until连用,表示这个动作或状态一直到until后所接的时间到来时才发生。
e.g.You shouldn't eat anything until you see the doctor.看过医生后,你才能吃东西。
2.so that“以便/为了……”,引导目的状语从句。
e.g.Please open the window so that we can breathe fresh air.请把窗户打开以便我们能呼吸新鲜的空气。
3.although=though意为“虽然;即使;纵然”,引导让步状语从句。
【注意】although和but不可用于同一个句子中。
e.g.Although he is very old,he is quite strong.他虽然年纪很大了,但还很强壮。
