二. 教學重點和難點：
1. 用兩個句型表達抱怨某事、某人的方法。
2. 修飾性副詞的使用。
3. 要點解析。
 
三. 具體內容：
（一）enough
  1. enough修飾形容詞或副詞時必須位于被修飾的詞語之后。修飾名詞時一般位于其前，也可位于其后。enough后面通常接不定式短語或介詞for短語。
    e.g. the question is easy enough.
       tom didn’t do his homework carefully enough.
       the water is cool enough to drink.
       we have enough tickets for all of you.
  2. 修飾形容詞時，如果用于否定句，則否定句在否定enough的同時，也否定了其后的不定式。
    e.g he is not careful enough to do the work.
       she is not old enough to go to school.
       enough如果修飾名詞，用于否定句時，不定式沒有被否定之意。
       e.g. there were not enough people to pick the apples.
  3. enough也可以做代詞，意思是“足夠，充足”。
    e.g. we have enough to do to complete the project.
 
（二）too…to…
    too+形容詞或副詞+(for sb.)+to do 表示“太……以至于不能……”，不定式雖然是肯定形式，但與前面的搭配構成了否定的含義。
    e.g. the book is too difficult for you to read.
       she is too short to catch the apples on the tree.
    在too…to結構中，too前面用了never這個詞，則動詞不定式可以把否定變為肯定。
    e.g it’s never too old to learn.
 
（三）修飾性副詞
     根據漢語意思，選擇恰當的修飾性副詞。
  1. a bit, really
    (1) these trousers are          tight.
    (2) i’m        sorry.
  2. rather, at all
    (1) she fell and hurt her leg         badly.
    (2) they are not friendly to me        .
  3. a little, extremely
    (1) she is        absent-minded.
    (2) mary found it        difficult to get a job.
    通過上面的測試，我們可以得出這樣的結論：
（1）rather, a bit, a little 可減輕形容詞的絕對性。
（2）really, extremely, quite 可起到強化形容詞的作用。
