- 试题详情及答案解析
- It is strongly ______ that the machines should be checked every year.
| A．recognized | B．recommended |
| C．recorded | D．recovered |
- 答案：B
- 试题分析：考查动词辨析。句意：(工人们)强烈建议机器每年检修一次。A认出，承认；B推荐，建议；C记录；D恢复，找回，重获。recommend在此是“建议，劝告”的意思，表示命令、要求、建议的词order, command, request, require, demand, suggest, recommend等后面的宾语从句用虚拟语气，即should+动词原形，should可省略，故选B。
