Question

【題目】Her son _____ the army for two months. She misses him very much.

A. has joined B. has been in

C. joined D. was in

Answer 1

【答案】B

【解析】

試題分析：句意：她兒子參軍兩個(gè)月了。她非常想念他。英語中，非延續(xù)性的動(dòng)作不能與表示一段時(shí)間的for、since短語連用，要把它改成可以延續(xù)的動(dòng)作或狀態(tài)。Join是一個(gè)非延續(xù)性動(dòng)作，將其改成“在軍隊(duì)”的狀態(tài)：be in the army才能與for、since短語連用；表示兒子參軍兩個(gè)月了，表示過去開始的動(dòng)作或狀態(tài)一直延續(xù)到現(xiàn)在，用現(xiàn)在完成時(shí)態(tài)。故選B。
