题目内容
8.To keep safe,everyone ______to wear a seat belt in the car.( )| A. | suppose | B. | will suppose | C. | is supposed | D. | supposes |
分析 为了安全,汽车里的每个人理应系安全带.
解答 答案:C.
首先根据题干"汽车里的每个人理应系安全带."表述的是客观事实,判断用一般现在时,观察四个选项都使用了suppose,再结合句意,可知本题考查句式"应该做某事",使用固定句式:be supposed to do,everyone作主语视为单数,所以be动词用is.故选C.
点评 be supposed to…其中to是动词不定式符号,不是介词,其后要跟动词原形.当be supposed to…的主语是"人"时,意为"应该…";"被期望…",它可以用来表示劝告、建议、义务、责任等,相当于情态动词should.如:Teachers are supposed to treat all the students alike.老师应该对所有的学生一视同仁.
