语法与词汇 5.Which of the following sentences is grammatically INCORRECT?(2013)

A、 Politics are the art or science of government.
B、 Ten miles seems like a long walk to me.
C、 Mumps is a kind of infectious disease.
D、 All the furniture has arrived undamaged.

【正确答案】 A

【答案解析】2013年第59题。B项ten miles看作整体单数，C项mumps腮腺炎，就是以．s结尾的疾病类名词，谓语动词用单数；D项furniture是集合名词，谓语动词用单数；A项politics是指政治学，是以-s结尾的学科类名词，谓语动词应该使用单数形式，故选A。注意：当politics作“政治见解”的意思时，谓语动词则使用复数。
