请问这个动词的变形,
now american researcher think they are close to developing a pill which will help people forget bad memories.请问develop这个词加
ing是不是为了把它变成名词使用?还是和谁的固定搭配?我记得动词加ing是为了做名词,家ed是为了做形容词,请问每个动词都可以那样变吗?
我知道加ing和ed并不都是这个原因，也有时态和语态或者固定用法会有这种变化方式。我是想问，这里加ing是不是这个原因，是不是可以在想不起动词或形容词时可以这样变形去用。

e close to v.+ing,to为介词
be close to 接近,靠近
其实你也可以从意思上这样理解,要“接近,靠近”什么东西,那么后面肯定是个名词,这样后面的动词就必须以ing形式变换成名词.当然这么想只是好记,真正原因是由于to这个介词.
动词加Ing和加ed并不是因为要做名词或者是形容词,而是表达的需要,这方面我也说不清楚.比如加ing也可能是因为现在进行时态,加ed是因为完成时态的原因.好好加强语法学习吧.
