often happen
is often happened
are often happened
often happens

答案为第一个 often happen

Traffic accidents交通事故，本句中为复数，有s,所以动词不必加s，所以可以排除第四个选项；
再看第二和第三个选项，交通事故的发生虽然是人为的，但不属于被动句的用法，不会用交通事故被发生这样说吧，所以不要被动句用法，排除第二和第三个选项。

这样得出正确选项 often happen 为第一个
选择题中象这样的排除法是很好用的！:)

Traffic accidents为主动，而且happen无被动形式！
所以选often happen

often happen
