这个问题考你两个方面:
expand 要用现在式或过去式?
要用 with 还是 through?
既然vocabulary 还在扩大,还没完成,所以过去式可以排除.
第二个乍看似乎有点纠结.with 是与阅读一起扩大vocabulary,through 是通过阅读扩大vocabulary;这里 reading 是指一种方法或工具,所以它是不能变大的,因此,只能选 through.
expand 要加 s , 那是因为 Vocabulary 是第三者单数,这我相信您是明白的.

孩子的词汇量通过阅读得到扩大。
expand可作为不及物动词, 【扩大】,故不用被动肯定对的。
expand也可作为及物动词,【使…变大】如:
Reading expands one's vocabulary.

If something expands or is expanded, it becomes larger. 扩大; 膨胀
说明被动主动都可以
但是被动一般是已经完成,这里没有这种意味,所以用expands就好
通过阅读扩大用介词through
