Question

【題目】Great changes ________ in my hometown since three years ago.

A.were taken placeB.have taken placeC.took placeD.have been taken place

Answer 1

【答案】B

【解析】

句意：自從三年前起，家鄉(xiāng)已經(jīng)發(fā)生了巨大的變化。

考查時(shí)態(tài)與語態(tài)。take place意為“發(fā)生”，不用被動語態(tài)，所以排除AD；根據(jù)時(shí)間標(biāo)志詞since，可知要用現(xiàn)在完成時(shí)have done，故選B。
