一个例句是:Getting mad at others means other people are getting control of your emotions中means引导的宾语从句中,people are getting control为什么要用进行时态 be+doing 的形式呢?不能直接用一般时态吗?这里是什么用法?
The types of molecules that can do this are themselves substantially hydrophobic in nature such as carbon dioxide, oxygen or ethanol.疑问:这句话中 themselves 是做表语么?那么 substantially hydrophobic 又是什么成分?
