在一份高考复习资料中，有这样一道选择填空题：We all 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[来源

很多学生选择 B．有的老师认为B．和:D．都可以。Z_xx_k.Com]

实际上，D才是正确答案。这道题的意思是：“我们都感觉是杰克和他的妻子应该对他们儿子在学校的恶劣行为负责。”题中的it is Jack as well as his wife that________for their son's bad performance at school是一个宾语从句，它是“it is/was+被强调部分+ that”这种结构的强调句， 这里被强调部分是主语Jack as well as his wife。如果主语部分有as well as，谓语动词的数应该与as well as前面的名词的数相同。在本题中，Jack是单数，在 be to后面的blame习惯用主动形式表示被动意义，而不用被动形式be blamed，所以B．is to be blamed不能作为正确答案，D．is to blame[能作为正确答案。be to blame意为“应负责任”、“受到责备”，这里的be to的意思是“应该”、“必须”。
