Question

【題目】A study shows the students who are engaged in after-school activities are happier than _________who are not.

A. onesB. those

C. theseD. them

Answer 1

【答案】B

【解析】

考查代詞。句意：一項(xiàng)研究表明，參加課外活動(dòng)的學(xué)生比不參加課外活動(dòng)的學(xué)生更開心。空格處代詞與the students是對(duì)應(yīng)關(guān)系，可以用the ones或者those替代。“them”指代的是前邊提到的復(fù)數(shù)名詞，不能與the students形成對(duì)應(yīng)關(guān)系。“these”一般不用定語(yǔ)從句修飾。故選B。
