新概念英语第2册Lesson16~18语法知识点 新概念英语第2册Lesson16语法知识点 条件句(Conditional sentences) (1)条件指某一事情完成之后其他事情才能发生。if通常的意思是“假如”，其后有时跟then(那么)。如果then没有道出，也会隐含在句子的意思内。if引导的条件从句不是指已经发生的事件，而是指能够发生、可能发生或可能发生过的事件。如果我们认为将来的事件很可能会发生，那么if 从句中要用一般现在时(有时也用其他形式的现在时)，主句中用will(或shall)加动词形式或其他形式的将来时: You’ll break that vase if you’re not careful. 你若是不小心，就会打碎花瓶的。 If I do,I’ll buy a new one. 如果我打碎了，我就买个新的。 What’ll you do if he doesn’t buy those pictures? 如果他不买那些画，你怎么办? I’m sure he will buy them,but if he doesn’t,I’ll buy them myself. 我敢肯定他会买的。不过如果他不买。那么我就自己买。 (2)主句中的will表示肯定如此或几乎可以肯定会如此。如果觉得其“肯定”程度达不到使用will的程度，或
者如果想表达建议等其他意思，就可以用别的情态助动词来代替will: Shall post these letters for you? 我替你将这些信发了好吗? You can post them if you want to. 如果你愿意，你可以把它们寄走。 If it’s fine tomorrow,we can/may go out. 如果明天天气好，我们可以/可能出门去。 (3)主句还可以用祈使语气等表示请求、建议等: Stay at home tomorrow if it rains. 明天如果下雨就呆在家里。 Please tell him to ring me if you see him. 如果你见到他，请让他给我打电话。 Please let me know if you can’t come. 如果你不能来，请告诉我一声。 新概念英语第2册Lesson17语法知识点 情态助动词must (1) must一般译为“必须”，可以表示“必要”、“命令或强制”、“邀请”、“决心”、“不可推卸的责任”等多种含义。它没有时态和人称变化，通常只用于现在时和将来时。在其他时态中，must的有些含义可以由have to或have got to 来补足。这3种形式一般可以互换，但彼此是有差别的。用

新概念英语第2册Lesson19~21语法知识点 新概念英语第2册Lesson19语法知识点 情态助动词can与may can(过去式为 could)原义为“能”，表示“有能力”、“能够”等： Can you drive a car? 你会开车吗? Jim couldn’t run very fast when he was a boy. 吉姆小时候不能跑很快。 (1)请求别人允许或答复时一般用 can，could，may和may的过去式 might。在这4个词中，can最常用，也最不正式;could比can表示更“犹豫”和客气，通常用在不能确定请求是否会得到同意的时候;may 比can和could更正式、更客气、更恭敬;might显得最犹豫，也最客气、最恭敬，但不及上述3个词常用。实际上，是一般性的请求时，can， could，may往往可以互换。含有情态助动词的普通答语为： 肯定： Of course you can/may. 你当然可以。(不可用could或might) 否定：
No, you can’t/may not. 不，你不可以。(不用could not或might not) 试体会下列例句中这些词的用法: Can I borrow your umbrella(please)? (请问)我能借用你的雨伞吗? Could I borrow your umbrella(please)? (请问)我可以借用一下你的雨伞吗? May I borrow your umbrella(please)? (请问)我可以借用您的雨伞吗? Might I borrow your umbrella(please)? (请问)我是否可以借用您的雨伞? (2)may和might还可以表示可能。如果说话人对所说事实确信无疑，就可以用be或其他完全动词： Jane is at home now. 简现在在家。(确切的事实) 但如果不敢确定，则可以说： Jane may/might be at home. 简可能/或许在家。 might比may更不确定。它们也可以表示过去可能已经发生过的事: Has the post arrived yet? 邮件来了吗? It may have arrived.Why don’t you ask John?He’s been in all day.
