问题描述:

the number of travelers during the spring festival this year is half——
a.of last years b.those of last year's c.that of last years d.it of last years为什么选c我知道选c我想知道为什么?

首先half应与指示代词放在一起用,所以A中直接使用
half+of错误。句子的主语是number,而不是travelers,所以后面应当用单数,就是that不选those。这种表达方式通常用that或those指代,不用it,这个知识点是外语的表达习惯,应当记准。

that 指代the number,因此,...is half the number of last year.
the number必须与the number 作比较.
