Question

 —It seems that his health is improving.
—Yes. It is ten years ___ he _____.

A．that, smoked

B．a(chǎn)fter, didn’t smoke

C．since, smoked

D．before, smoked

Answer 1

C

在It’s--------since-----句中，若動詞為延續(xù)性動詞，則表示其動詞的反義概念。It’s 10 years since he smoked.表示他已戒煙十年了。等于It’s 10 years since he gave up smoking. 故選C。
