2019年mpa考试英语真题——连词223

{01} —It seems that his health is improving.
—Yes. It is ten years ___ he _____. A.that, smoked B.after, didn’t smoke C.since, smoked D.before, smoked 解析：在It’s--------since-----句中，若动词为延续性动词，则表示其动词的反义概念。It’s 10 years since he smoked.表示他已戒烟十年了。等于It’s 10 years since he gave up smoking. 故选C。
本题选C。
{02}— May I go and play with Dick this afternoon, Mum?
No, you can’t go out _______ your work is being done. A.before B.until C.as D.the moment 解析：本题易误选B。根据后面的…is being done可以看出“因为你正在做作业，所以不能出去。”其他选项不符合句意。
本题选C。
