高二英語Sporting events教案
4.表示預言。oil will float on water.
5.用“will be”和“will十have十過去分詞”的結構表示推測，主要用于第二、三人稱。前者表示對目前情況的推測，后者表示對已經完成的動作或事態的推測。this will be the book you want.
he will have arrived by now.
6.would可表示過去反復發生的動作或某種傾向。would表過去習慣時比used to正式。并沒有“現已無此習慣”的含義。the wound would not heal.
during the vacation he would visit me every week.
7.表料想或猜想。it would be about ten when he left home.
what would she be doing there?
i thought he would have told you all about it.
8.would like； would like to do = want to 想要，為固定搭配。
would you like to go with me?
9. will you…? would you like…? 表示肯定含義的請求勸說時，疑問句中一般用some, 而不是any。 would you like some cake?
10. 否定結構中用will，一般不用would, won't you是一種委婉語氣。
won't you sit down?
六.shall, should 和ought to
1. shall用于第一人稱表示征求對方的意見： what shall we do next?
2. shall用于第一、第三人稱疑問句中.表示說話人征求對方的意見或向對方請示。shall we begin our meeting? when shall we leave the hospital?
3. shall用于第二 、第三人稱，表示說話人給對方的命令、警告、允諾或威脅。you shall fail if you don’t work harder.(警告) ; he shall have a book when i finish reading (允諾); he shall be punished.(威脅)
4. 表示推測或可能。 they should finish the work by now.
5. should表示勸告、義務、建議、命令，其同義詞是ought to；在疑問句中。通常用should代替ought to。we should learn some english. you should go to class right away. should i open the window?
注意： should的含義較多，用法靈活。現介紹三種其特殊用法。請看下面句子： i should think it would be better to try it again.我倒是認為最好再試一試。 you are mistaken. i should say.依我看，你是搞錯了。
i should advise you not to do that我倒是勸你別這樣做。
this is something i should have liked to ask you.這是我本來想問你的。
從以上例句可以看出：情態動詞should用于第一人稱時可以表示說話人的一種謙遜、客氣、委婉的語氣。
此外,why / how_+ should結構表示說話人對某事不能理解，感到以外、贊嘆、憤怒、驚異等感情，意思為“竟會”。例如：
why should you be so late today? 你今天怎么來這么晚？
--where is betty living? betty住哪兒？ --how should i?我怎么回知道。
i don’t know why you should think that i did it.我真不知道你憑什么認為這件事是我干的。
6. should表示允許。it should be ready at noon.
7. should +have +過去分詞, 表示應該做而實際上沒有做到.
