Question

【題目】There is some evidence, scientists report, ________ eating garlic may guard against cancer.

A.whichB.thatC.asD.who

Answer 1

【答案】B

【解析】

考查同位語(yǔ)從句的連接詞。句意：科學(xué)家報(bào)告說(shuō)，有一些證據(jù)表明吃大蒜可以預(yù)防癌癥。分析句子成分可知，scientists report 是插入語(yǔ)，some evidence和eating garlic may guard against cancer是同位語(yǔ)，因此要用that連接，且that不充當(dāng)成分，也不能省略。故選B項(xiàng)。
