【題目】The physics teacher taught us last term that light ________ faster than sound.

A.traveledB.travelsC.had traveled

【答案】B

【解析】

句意:上學(xué)期,物理老師教我們光線比聲音傳播的快。

考查賓語從句的時(shí)態(tài)。traveled是一般過去時(shí)態(tài);travels是一般現(xiàn)在時(shí)態(tài);had traveled是過去完成時(shí)。光線傳播比聲音快是科學(xué)真理,賓語從句中用一般現(xiàn)在時(shí)態(tài),故選B。
