Question

【題目】—I think Amy and Steve can help me with the school project.

—But they ________ back to Australia.

A. go B. went C. have gone D. were going

Answer 1

【答案】C

【解析】句意：-我認為Amy和Steve能幫助我做這個學(xué)校項目。-但是他們已經(jīng)回到了澳大利亞。go去，動詞原形；went是go的過去式；have gone是現(xiàn)在完成時；were going過去進行時態(tài)。根據(jù)句意But可知，Amy和Steve兩個人不能幫助他，因為他們已經(jīng)回去了，應(yīng)該用現(xiàn)在完成時態(tài)，故選C。
