求50道英语选择题

.Every student as well as some teachers who（ ）to visit the museum（ ）asked to be at the school gate before 7 :30 in the morning
A are;are B is;is C are;is D is;are
答：C
译：要求每一个学生（以及一些要去参观博物馆的老师）上午7：30之前赶到校门口.
析：此题考查定语从句及主句的主谓一致.定语从句who are to visit the museum的先行词为some teachers,所以用are,排除BD.此句的“真主”为every student,是单数概念,其谓语动词用单数,排除D,剩下A.
评：as well as/ together with/ along with +复数名词,是介词短语,常故意紧靠单数的主语,让学生以为主语是复数,这是出题者常见伎俩,不可上当.学会去伪存真,找出真正的主语.
其实本题句造得不好,不知道这些学生去不去博物馆.不如说：All the students and the teachers who are to visit the museum are asked to .,意思明了,句子合理.
2.How much ( ) the shoes?
Five dollars ( ) enough.
A is;is B are;is C are;are D is;are
答：B
译：这双鞋多少钱?
五元足够了.
析：此题也是考主谓一致.第一句是疑问句,主语在最后the shoes,是复数,故用are,排除AD
第二句中的主语是five dollars,虽然是复数,但是作为一个整体来看,是一笔钱,是一个单数的概念,所以选B最佳.
评：这个对话也不是很符合实际.此对话应为买卖双方之间进行.卖者要么说：Five dollars,要么说：Only five dollars,不会那样回答.好象这鞋不值钱似的.纯为出题而生造句子.
