Question

【题目】— 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

Answer 1

【答案】B
【解析】句意：——人们在网上能找到大量的有用的信息。——是的，学会用电脑很重要。a large amount of大量的，只修饰不可数名词；a large number of许多，只修饰可数名词的复数。句型：It is +形容词+to do sth做某事是……的。it指代后面的不定式。故选B。
