to be + adjective + enough + to-infinitive

☆当该结构的主语是指人时，用来描述该人的性格特征及能力      

     e.g. Betty is generous enough to buy souvenirs for all her classmates.

           Amy is old enough to wash her own clothes.

  ☆当该结构的主语是指事物时，用来描述某事物的特征，此时，enough后通常加“for sb.”。      

     e.g. The car is cheap enough for Tom to buy.

3. Suzy wants to tell her parents what she thinks about her friends. Help her make sentences using “to be + adjective + enough + to-infinitive”.

    Sandy _________________________________________

4. We can use the verb to be + too + adjective + to-infinitive to express a negative result.

 “be + too + adj. + to do sth.”意为“太……而不能……”，动词不定式表示

的是一个否定意义的结果。

☆当该结构的主语是指人时，用来说明由于该人的某种特质而不能做某事。

British people are very polite. They do not shout loudly in public.

      British people are too polite to shout loudly in public.

      British people are very polite. They will not push past you.

British people are too polite to push past you.

5. Sometimes we need to add for someone before the to-infinitive.

  ☆当该结构的主语是指事物时，在to do sth.之前可以加“for sb.”，用来强

    调“不可能的结果”的对象是谁。

  e.g. The box is too heavy for the boy to carry. 

      The print is too small for me to read without glasses.

      The UK is very far away. Jenny cannot go there on her own.
