Question

When you talk with a stranger, be ______ one thing: don't talk much about yourself.

A. interested in    B. careful about

C. good at    D. frightened of

Answer

B

【解析】句意：当你和陌生人交谈时，要注意一件事：不要多谈自己。考查形容词短语辨析。be interested in意为“对……感兴趣”；be careful about意为“当心，注意”；be good at意为“擅长”；be frightened of意为“害怕”。根据语境可知ACD三项意思都与句意不合，故选B。
