二. 本周教學(xué)重點：
1. too…to…, not … enough to do
2. modifying adverbs
3. giving reasons
4. making contrast
5. talk about personalities.
 
三. 具體內(nèi)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?jīng)]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(gòu)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(jié)構(gòu)中，too前面用了never這個詞，則動詞不定式可以把否定變?yōu)榭隙ā?br>    e.g. it’s never too old to learn.
 
（三）修飾性副詞。
    根據(jù)漢語意思，選擇恰當(dāng)?shù)男揎椥愿痹~。
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。
3. at all用于否定句加強語氣。
e.g. he is rather stubborn.
  i am a little careless.
  she is a bit absent-minded.
  he is extremely patient.
  i am not serious at all.
  they’re quite friendly.
 
（四）to give reasons and purposes
e.g. 1)—why did you get a pet?
—to have company.
2)—why do they use animals for treatment?
  —because they help people relax.
3)—why do you talk to your parents about everything?
  —so they trust me.
4)i want a pet to take it for walk.
5)animals are good listeners because they don’t stop you.
to表示目的：doctors use animals to help people feel better.
because表示原因：i love cats because they are very clean.
so表示結(jié)果：people have pets so they don’t feel better.
