看来你对动词和时态很不熟悉,
“what happening? ”是错的,
这句话主语是what,动词是happen,
而happening是现在分词,
说明这句话是进行时态,
但进行时态的构成是“be+现在分词”,
而不是孤零零的现在分词,
所以正确的说法是“what is happening?”
再看What happened?
这句话的主语是what,动词是happen,
由于时态是一般过去时,
(动作发生在过去),
所以动词用过去式,
正确
而“what did happen?”就不对了,
因为过去时陈述句的一般结构为“主语+过去式”,
所以did是多余的,
那么为什么有时候会看到动词前面加did呢?
这涉及到动词和句子的分类问题,
动词包括实义动词和助动词等,
象happen是“实义动词”,
“do,does,did”是助动词,
而句子包括陈述句、疑问句等,
陈述句又分为肯定句和否定句,
象“What happened?”就属于陈述句、肯定句,
实义动词用于肯定陈述句的一般结构为(以一般过去时为例):
“主语+过去式”
而这类句子要变成否定句,
就需要在实义动词前加助动词did,再加not,
再把动词变成原形,
即:What did not happen?
而变成疑问句,
则需要在句首加did,
动词变原形
即:Did what happen?
(最好把动词分类,句子分类,
各种时态的构成,
各种句子的构成仔细看一看,
有问题可以再问)
是what is happening or what's happening .因为事情已经发生了所以HAPPEN 要变过去式
