Question

Research shows that teenagers ________ talk about their day with family members at the dinner table are less likely to engage in high-risk behavior.

A．what

B．who

C．whom

D．\

Answer 1

B

解析試題分析：考查定語(yǔ)從句。本句中先行詞為the teenagers，在定語(yǔ)從句中做主語(yǔ)，不能省略。What不能引導(dǎo)定語(yǔ)從句；whom在句中通常做賓語(yǔ)。句意：研究說(shuō)明那些在吃飯的時(shí)候和家人談?wù)摵芏鄬W(xué)校事情的年輕人不太可能染上危險(xiǎn)的行為。故B正確。
