【題目】— People can find _____ useful information on the Internet.
— Yes. It's important ____ to use computers.

A.a large amount of; learning
B.a large amount of; to learn
C.a large number of; learning
D.a large number of; to learn

【答案】B
【解析】句意：——人們在網(wǎng)上能找到大量的有用的信息�！堑�，學會用電腦很重要。a large amount of大量的，只修飾不可數(shù)名詞；a large number of許多，只修飾可數(shù)名詞的復數(shù)。句型：It is +形容詞+to do sth做某事是……的。it指代后面的不定式。故選B。

【題目】閱讀短文，下列問題
D
Pupils spend more time at school than they spend with their parents. So communication (變流) between them can be difficult. Parents spend the whole day on work and they come home in the evening. Then they hardly talk with or pay attention to (注意) their children. And it is worse (更不好的) if parents work in another town. Parents and children only spend weekends together.
