问题补充:
I feel it is Jack as well as his wife that for their son’s bad performance at school.
A. are to blame
B. is to be blamed
C. are to be blamed
D. is to blame
答案:
A. are to blame
B. is to be blamed
C. are to be blamed
(答案→)D. is to blame
解析:考查主谓一致和固定词组。“A+ as well as+ B”做主语的时候,谓语动词和A保持一致;固定词组be to blame该受责备;用主动语态表示被动的含义。句意:我感觉Jack和他的妻子应该为儿子在学校的不好的表现负责。故D正确。
