如: why can't we do the work ourselves? can you work our this problem youself?都不加介词,而 we must not think only of ourselves.怎么加介词of 呢?如不加of 语法能通吗?谢谢。
A thousand thanks for your kindness, 那 he lives in London by himself. I can't leave her by herself, 这里的 live和 leave都是不及物动词了是吗?
追答live为不及物动词,leave是及物动词。
但是它们和oneself没有关系,反身代词又不是做它们的宾语。
此处反身代词都做介词by的短语,构成固定短语by oneself,意思是“单独/独力/靠自己”。
