Being exposed to sunlight for too much time will do harm to one's skin.
Being exposed to sunlight for too much time will do harm to one's skin.
这个句子的主语是Being exposed to sunlight for too much time,还是Being exposed
主语里面的成分各是什么?
如果去掉Being行吗?
will do是谓语部分,所以前面整个是动名词的复合结构做主语.
be exposed to sth表示被暴露在.下
for too much time 介词短语,指太长时间.
你如果把being去掉就只能是过去分词了,过去分词是不能做主语的.
Exposed to sunlight for too much time,your skin will get sunburnt.
如果做状语,就可以去掉了.前面的动名词并没有逻辑主语,为什么说是复合结构呢?主语并非exposed,而是Being exposed to sunlight for too much time。那为什么不能去掉呢?我说的复合结构是指不是单单的being done还加了for too much time这些东西,当然这个东西去掉句子也没有错误。being done叫动名词的被动,它是个整体,being当然不能去。done叫过去分词可是过去分词也可以表被动啊,只是没有表示正在进行。你说的对,但过去分词不能做主语。表示正在进行的是现在分词不是动名词。可是主语并非exposed,而是Being exposed to sunlight for too much timeBeing exposed to sunlight for too much time,这个之所以说是主语,就是要看expose,不然句子就错了。being exposed才能做主语,它是主语的最主要成分,be expsed to sth.所以sunlight是这个短语要加的宾语部分。for too much time是状语可以去掉。
