问题描述：
As we know,things like that _____ all over the world every day.要原因!
A.happens B.are happened C.are happening D.will be happened
答
选C every day 说明要用一般现在时态，happen没有被动语态，所以B、D不对。A用的是单三式，things用的是复数，所以不对。选C
答
C
things为复数，且happen 无被动。
答
C,things是主语，复数形式like that 是定语，空格处是谓语，首先排除A, 然后B和D格式不对。
答
happen
happen"随机、偶然地发生"
答
选C,这里的主语是things,like that 是后置定语...
