Unit 13 The water planet教學(xué)設(shè)計(jì)

  if i have a choice, i had sooner not continue my studies at this school. 
i would rather stay here than go home. = i would stay here rather than go home.
典型例題
----shall we go skating or stay at home?
----which ___ do?
 a. do you rather b. would you rather c. will you rather d. should you rather
答案b。本題考查情態(tài)動(dòng)詞rather的用法，would rather +do sth 意為"寧愿"，本題為疑問句，would 提前，所以選b。
11 will和would
注意：1）would like；would like to do = want to 想要，為固定搭配。例如：
      would you like to go with me? 想和我一塊去嗎？
      2）will you…?　would you like…? 表示肯定含義的請(qǐng)求勸說時(shí)，疑問句中一般用some, 而不是any。例如：
         would you like some cake? 吃點(diǎn)蛋糕吧。
      3）否定結(jié)構(gòu)中用will，一般不用would, won't you是一種委婉語氣。
         won't you sit down? 你不坐下嗎？
12 情態(tài)動(dòng)詞的回答方式
問句 肯定回答 否定回答
need you…? yes, i must. no, i needn't
must you…?  no, i don't have to.
典型例題
1）---could i borrow your dictionary?
   ---yes, of course, you____.
 a. might b. will  c. can  d. should
    答案c. could表示委婉的語氣，并不為時(shí)態(tài)。答語中of course，表示肯定的語氣，允許某人做某事時(shí)，用can和 may來表達(dá)，不能用could或might。will 與you連用，用來提出要求或下命令。should與you 連用，用來提出勸告。
2）---shall i tell john about it?
 ---no, you ___. i've told him already.
  a. needn't b. wouldn't c. mustn't d. shouldn't
  答案a。needn't 不必，不用。 wouldn't 將不, 不會(huì)的。 mustn't 禁止、不能。 shouldn't　不應(yīng)該。本題為不需要，不必的意思，應(yīng)用needn't。
3）---don't forget to come to my birthday party tomorrow.
  ---______.
 a. i don't  b.i won't  c. i can't d. i haven't
答案b. will既可當(dāng)作情態(tài)動(dòng)詞，表請(qǐng)求、建議、也可作為實(shí)義動(dòng)詞表"意愿、意志、決心"，本題表示決心，選b。
13 帶to 的情態(tài)動(dòng)詞
 帶to 的情態(tài)動(dòng)詞有四個(gè)：ought to, have to, used to, be to, 如加上have got to （=must）, be able to，為六個(gè)。它們的疑問、否定形式應(yīng)予以注意：
 do they have to pay their bill before the end of the month?
 she didn't use to play tennis before she was fourteen.
 you ought not to have told her all about it.
 ought he to see a heart specialist at once.?
ought to 本身作為情態(tài)動(dòng)詞使用。其他的詞作為實(shí)義動(dòng)詞使用，變疑問，否定時(shí)，須有do 等助動(dòng)詞協(xié)助。
