Answer 1

英语语法：不及物动词有完成时，但是无被动式；现在完成时的肯定句和一段时间状语连用时必须用持续性动词
A happen 是不及物动词，所以无被动语态，排除C,D
并且happen是瞬时性动词，一般不用于完成时
从麦克米伦字典中查寻：你会发现，里面没有任何的被动用法和完成时用法

Answer 2

选A，happen是不及物动词，没有被动语态，所以不选CD，而后面有具体的日期所以是过去时，而不是现在完成时，绝对是选A

Answer 3

A
happen没有被动（take place也一样），按时间来说已经是过去时，当然只能选A了 。

Answer 4

A
1、happen无被动
2、“on” the morning of July 1. 是具体的“时间点”，发生在过去，用过去时
3、完成时用在“一段”时间，后面的介词不用on，用since.有时也用for
