2019中考英语语法常见习惯用语知识复习

　　常见习惯用语
　　（一）　知识概要
　　由于英语国家的语言习惯与中国的语言习惯有许多不同之处，所以造成了许多同学在做选择或书写，或与人交谈中造成误用中国方式来对英语的问句作解答。例如一个小女孩十分好看，可爱，外国人见到时会讲： you are so beautiful  这时的答语应该是 thank you  如果外国人发现你的英语不错，他们会讲： your english is very good  这时中国人常常会说：不，我说的不好。这纯是一种礼貌的答语，但是不符合英语习惯。它正确的答语应是 thank you  虽然交际英语 有一些规律可讲，但更重要的是学习外国的生活习惯，了解他们的文化背景，历史渊源，这样才能真正的学好一门外语。
　　（二）　正误辨析
　　［误］ - what can i do for you?
　　- yes， please help me
　　［正］ - what can i do for you?
　　- i＂d like to buy a sweater
　　［析］ what can i do for you? 这一问语实际上用于的情景很多，要根据具体情况而定。如在商店中售货员讲这句话应译为：您想要点什么?在其他场合也可以被译为：我能为您做些什么?它的答语应是直接讲出想让对方提供的帮助。
　　［误］ - which colour do you like?
　　- sorry， i don＂t like
　　［正］ - which colour do you like?
　　- i prefer blue
　　［析］ 由 which 来提问的问句是要回答具体的选择，而不能泛指，泛泛的回答。如 yes， i like it
　　［误］ do you like to come with us tonight?
　　［正］ would you like to come with us tonight?
　　［析］ do you like … 问的是对方的习惯，如： do you like swimming? do you like collecting stamps? 而 would you like … 则是一次性的邀请、提议。邀请的英语表达法还有如下几种：
　　shall we go? 我们走吧!
　　let＂s go? 让我们走吧!
　　how about having a cup of tea? 喝杯茶如何?
　　what about a cup of coffee  喝杯咖啡如何?
　　why not buy it? 为什么不买呢?
　　其肯定答语一般为certainly， yes， o．ｋ．　all right， with pleasure
　　［误］ sorry， i＂ve kept you waiting
　　not at all
　　［正］ sorry， i＂ve kept you waiting
　　never mind
　　［析］ ＂介意不介意＂这一问法与答语在中英文中有所不同。如：
　　- do you mind my smoking here? - ＿＿＿＿＿＿＿＿＿
　　ａ．　yes， do it please
　　ｂ．　no， of course not
　　ｃ．　yes， take it please
　　ｄ．　no， you can＂t take it
　　这时正确的选择应是b。 其意为：不介意，当然不。而a选项则自相矛盾了，它应译为：是的我介意，请抽吧。而 d选项是：不介意，你不能抽。当向对方争求意见时，可以有以下问法：
　　do you mind if i open the door?
　　would you mind mailing the letter for me
　　其答语如果是同意应为： certainly not， not at all
　　而不同意时应为 yes， 或 i＂m sorry
　　［误］ what＂s that man?
　　he is mike
　　［正］ what＂s that man?
　　he is a teacher
　　［正］ who＂s that man?
　　he is mike  (he is mike＂s father )
　　［析］ 由 what 提问是问的职业，由 who 提问问的是姓名或身份。
　　［误］ - how much are they?
　　- half a kilo， please
　　［正］ - how many bananas do you want?
　　- half a kilo  please
　　［析］ how much are they? 问的是价格而不是实际物品的多少。
　　［误］ i＂m sorry， but is this the way to the park?
　　［正］ excuse me， but is this the way to the park?
　　［析］ i＂m sorry 是对已经做错了的事向对方道歉时的开始语。而 excuse me  是在打扰对方之前表达歉意的话。
　　［误］ - have a good time tonight!
　　- you are the same
　　［正］ - have a good time tonight!
　　- the same to you
　　［析］ the same to you 是表达我也祝您有个愉快的夜晚，它是美语中的习惯用法。
　　［误］ - what＂s the problem?
　　- i＂ve got a headache
　　［正］ what＂s wrong with you?
　　i＂ve got a headache
　　［析］ what＂s wrong with you? 是询问对方身体状态如何，而 what＂s the problem?是问对方遇到了什么麻烦。
　　［误］ - now， i＂m back  can i play?
　　- perhaps  you＂d better do your homework first
　　［正］ - now， i＂m back  can i play?
　　- i＂m afraid not  you＂d better do your homework first
　　［析］ perhaps 是表示对一种拿不准的事态的推论，如： am i right? perhaps 而 i＂m afraid not  则表达一种不同意的态度。 be afraid 的几种用法有：
　　i＂m afraid that you are right
　　其后直接加宾语从句。
　　- will you come to my birthday party?
　　- i＂m afraid not  i have to go to see my father  he is in hospital
　　其后 not，表示否定。
　　- sor ry， i don＂t want to go there alone， i＂m afraid of the dog
　　其后 名词，表示对某人，某物的害怕。
　　mary is afraid of making mistakes in the exam
　　其后  of   动名词，表示害怕做某事。
　　mary is afraid to see the teacher because she didn＂t do well in the exam
　　其后  不定式，表示不敢去做某事。
　　［误］ - how soon will you be ready?
　　- two days
　　［正］ - how soon will you be ready?
　　- in two days
　　［析］ 此题关键是要根据情景，身临其境，要注意的是对方问了什么，就应答什么。或答了什么就应问什么。 how soon 问的是＂还有多久才能作完＂，这时要用 in two days， 即在两小时之内即可以作完。如用 how long 提问，则答语可以用 two days。
　　［误］ - would you mind if i have some time off?
　　- i don＂t mind
　　- monday and tuesday of next week
　　［正］ - would you mind if i have some t ime off?
　　- when exactly
　　- monday and tuesday of next week
　　［析］ 有的对话是复杂的，稍有不慎就有可能选错，而且英语中如选错了答案是不容易找出错来的。 i don＂t mind 是可以用来回答 would you mind…这一提问的，但如仔细看一看则会发现我们要选用的不是陈述句而是疑问句。根据下面一句的答语来判定要用 when exactly? 什么时间，这样才能与下句中具体的时间相符合。
　　［误］ suppose your name is tom  the phone rings and you pick it up  the first word you say will probably be ＂who are you?＂
　　［正］ suppose your name is tom  the phone rings and you pick it up  the first word you say will probably be ＂hello? this is tom speaking?＂
　　［析］ 在英语学习中，习惯用法实际上在某种情况，或某种意义上讲比语法更为重要。如果只从句子的角度上去分析，它们可能都是对的。比如，当你拿起电话时，如果你想知道对方是谁，可以问＂who＂s that(speaking)?＂但不要讲＂who are you?＂如果你想先介绍一下自己可以讲＂this is   speaking＂而不要讲＂i＂m　 ＂也不要讲＂my name is  ．＂　就语法而论，＂who are you?＂ ＂i＂m  ＂＂my name is  ＂并不错，也是英语中可用的句子，但就打电话这一场合，就不宜用了。
　　［误］ - do you think it＂s going to rain over the weekend?
　　- i don＂t hope so
　　［正］ - do you think it＂s going to rain over the weekend?
　　- i hope not
　　［析］ 由于初学者对实际英语口语中表达感情意愿的答语不熟悉，如在肯定答语中 i think so  i hope so  i believe so  是相同的，但在否定句中却常用 i don＂t think so  但i don＂t believe so  和 i don＂t hope so  则意为：我不信此事和我不希望此事发生。而 i believe not  和 i hope not  则为：我想可能不会发生吧!
　　［误］ - is anybody there?
　　- no， bob and tom have asked for leave
　　［正］ - is everybody there?
　　- no， bob and tom have asked for leave
　　［析］ 许多学生在写作和选择答语或问句时总要语法在前 ，而不是习惯用语在先。所以总是要拘泥疑问句中的不定代词，用 anybody。 但是is anybody there? 在英语中为：这里有人吗?而is everybody there?为：全都到齐了吗?所以首先要考虑的是其答语。 no， bob and tom have asked for leave
　　［误］ - your handwriting is very good!
　　- no， my handwriting is very poor
　　［正］ - your handwriting is very good!
　　- thank you
　　［析］ 中国人遇到别人称赞，总是以谦逊为美德。但英美人则往往认为自信是美德。所以当别人夸奖 你或赞美你时，就应说： thank you  又比如中国人见面时常讲 where are you going? 或 have you had your breakfast yet?而英美人则认为你过多的干预别人的私生活了。而他们见面时往往问一些无关紧要的话，如： hello! how are you going? (你过得怎样) morning! 等。而 good morning  和 how do you do  则被认为是较正规的问候语，在日常生活中则十分少见。
　　［误］ when you have had dinner with an american friend and want to leave you may say： ＂excuse me  i＂ll go first ＂
　　［正］ when you have had dinner with an american friend and want to leave you may say： ＂excuse me  i have to go ＂
　　［析］ 这两句答语都是正确的，其关键不是语法，而是习惯问题。如果在这样的场合你讲 i＂ll go first  朋友们会迷惑不解，而 i have to go  则表示由于外界的特殊原因而造成的你要离去，而你本人则十分不愿做此事。
　　［误］ - would you like to come to dinner tonight?
　　- i＂d like to， and i＂m too busy
　　［正］ - would you like to come to dinner tonight?
　　- i＂d like to， but i＂m too busy
　　［析］ i＂m too busy  与 i＂d like to  在意义上正好相反。所以要用转折连词。这里考查了对词义合乎逻辑的表达能力。所以要强调语言环境，更要强调在语言的基础上的词语辨析。
　　［误］ - where＂s deter?
　　- deter will come with us tonight but he isn＂t very sure yet
　　［正］ - where＂s deter?
　　- deter may come with us tonight but he isn＂t very sure yet
　　［析］ 由于 but 所引出的句子可以看出 deter 的来与不来是十分不确定的，所以应用 may 来表达一个不肯定的事件。
　　［误］ - hi， haven＂t seen you for ages! you look fine!
　　- great  you look well too
　　［正］ - hi， haven＂t seen you for ages! you look fine!
　　- thanks  you look well too
　　［析］ 要注意的是 great 在口语中多表示惊叹，而 thanks 则表示感谢对方的称赞。 所以对情景谈话要有准确的判定，要根据情景，身临其境，上下对照，周密思考，弄清场合，注意英美人的风俗习惯，注重语义上的词语辨析，并要进行大量的语言实践练习，扩大实际交际能力。
