问题描述：
Every year many people _____vacation in Hangzhou.
填介词或副词
答
不太可能是介词副词吧，缺谓语
答
are on
答
for
答
Every year many people (have) vacations in Hangzhou.
Every year many people (take) vacations in Hangzhou.
Every year many people (go on) vacations in Hangzhou.

on
若是只能填介词或副词,这就只是一个名词词组,不是一个句子
要是变句子则需加上动词are或go在on前
