Question

When people move to another country, they often try _________ the custom of their native land.

A．to keep on

B．to keep off

C．to keep up

D．to keep down

Answer 1

C

试题分析：短语辨析。Keep on继续；keep off使…不接近；keep up保持，跟上；keep down控制，压制；句意：当人们搬到一个新的国家，他们总是努力跟上当地人的风俗习惯。故C正确。
点评：本题考查了keep的短语，都是考查的重点内容，本题的keep off, keep up的一词多义现象。
