Question

【題目】He _____ to play ____ before he was 11 years old.

A. had learned, piano B. had learned, the piano

C. has learned, the piano D. learns, piano.

Answer 1

【答案】B

【解析】時(shí)間狀語before he was 11 years old是過去時(shí)，主句的動(dòng)作發(fā)生在這個(gè)時(shí)間之前，表示“過去的過去”，應(yīng)當(dāng)用過去完成時(shí)；piano是西洋樂器，與play連用時(shí)，前面應(yīng)當(dāng)加the。
