英语语法解释

英语语法解释until they became aware of his constant frown.
直到后来她们感到他不住地皱眉。
我总觉得应该这样才对：until they became aware of his frowning continually.
这样的话his就是frowning的逻辑主语，frowning是动名词，总感觉之前的句子语法不对，谁能帮忙解释一下？

Answer 1

until they became aware of his constant frown.　这个从句中，frown 是名词，his 和 constant 都是形容词，修饰 frown.，短语 his constant frown 作became aware of 的宾语。 所以，语法是正确的。

而你的说法： until they became aware of his frowning continually/constantly. 也是正确的，你是把 frown 当作动词使用，放在 介词 of之后使用动名词。可以说得通。所以两种说法都正确。

追问

请问，这句话的结构是主系表，his constant frown怎么是宾语了，这句话的整体结构是什么？主＋系＋表＋宾？

Answer 2

第一句原句语法上没问题啊 be aware of +一个名词词组 对的呀 ，然后 我要说一点有名词最好用名词，不要用动名词，这是一般习惯，那个frown 已经是名词了。何必还要再加一笔呢
