Question

【題目】Physics _________much easier for me since Mrs. Yang began to teach us.

A. have been B. has been C. was D. were

Answer 1

【答案】B

【解析】

試題分析：句意：自從楊老師開(kāi)始教我們以來(lái)，物理對(duì)于我來(lái)說(shuō)容易多了。結(jié)合語(yǔ)境可知本句描述的是從過(guò)去某時(shí)已知持續(xù)到現(xiàn)在的動(dòng)作，故用現(xiàn)在完成時(shí)態(tài)。主語(yǔ)physics表示抽象含義，不可數(shù)，故助動(dòng)詞用單數(shù)。選B。
