名词复数:asses词意辨析：
as, because, for, since这些连词均含有“因为”之意。
as: 从属连词，语意较because, since弱，着重在主句，所表示的原因或理由是“附带的”。
because: 从属连词，语意强，着重直接的原因或理由，所引出的从句是全句的重心，用以回答why提出的问题。
for: 并列连词，语气较弱，所引出的句子一般放在后面，表示附带说明的理由或推断理由。
since: 语意比because弱，但比as强，一般用于表示“由于大家已知的事实”。as, like这两个词均有“像”之意。
as: 从属连词，引出方式从句。
like: 是前置词，后面跟的是宾语。though, although, as, even though这些连词均可表示“虽然，尽管”之意。
though: 和although在意义上几乎毫无区别，但在习惯用法上这两个词仍有以下一些差异：1.though可引出倒装语序的让步状语从句，although 则不能。2.though可与even连用，although则不能；在as though结构中，只用though，不能用although。3.though可以置于从句末，而although则不能。4.引出省略句时，通常用though。
although: 与though在意义上相似，但文体上是比较正式用词，语气比though强。
as: 引出让步状语从句只用于倒装语序结构中，语气强于上述两个连词。
even though: （＝even if），意为“即使”，引导让步状语从句。though也引导让步状语从句，意为“虽然”；even though有退一步设想的意味，与though不同。though引导的句子所说的是事实，even though引导的句子所说的则不一定是事实。例如：he will not tell the secret even though（even if）he knows it．
即使他知道这个秘密，他也不肯说出来。he will not tell the secret though he knows it．
他虽然知道这个秘密，但他不会说出来。when, while, as这些连词均可表示“当……时”引出时间从句。
when: 所引导的从句，其谓语动词既可是持续动词，也可是短暂动词；谓语动词动作发生的时间可以与主句谓语动词的动作是同时，或之前、之后。
while: 句中的谓语动词应为持续动词，不用短暂动词，谓语动作发生的时间通常与主句谓语动词动作发生时间是同时。
as: 侧重指从句与主句的动作同时进行，谓语动词可以是持续性的，可以是短暂性动词。英语解释：
