Question

【題目】Television enables us to see things happen almost at the exact moment ________.

A.which they are happening

B.when they are happening

C.which is happening

D.when they have happened

Answer 1

【答案】B

【解析】

考查定語從句。句意：電視使我們幾乎在事情發(fā)生的同一時刻看到它們發(fā)生。此處moment是先行詞，在后面的定語從句中作時間狀語，用when引導(dǎo)定語從句，再根據(jù)at the exact moment可知動作正在進(jìn)行，所以用現(xiàn)在進(jìn)行時態(tài)，故選B。
