请问老师let alone当中alone是副词么?
We don’t have enough room for another guest, let alone an entire family.
同样这句话中为什么没有并列连词呢?只是用逗号隔开。
Don’t touch it let it alone.
这里的alone是否是形容词做宾补 Leave me alone 同理是否也是形容词做状语?
let alone 有两种用法。
1. 用于祈使句或一般句子,let 后接宾语,alone 是副词作宾补。例如:
Let me alone. 让我静静。
Don’t touch it; let it alone. 别碰它,任其自然。
We had to let the boy alone, because he was bothering. 我们不得不让那个男孩一个人呆着,因为他很烦。
alone 之所以认定是副词,因为结构跟这些句子一致:
Let him in.
Let the dog out.
Let the man outside.
2. let alone:习语。“更不必说”,等于to say nothing of,一般用作插入成分(或独立成分)。针对上一个否定句,作进一步的否定。let alone 不可分开。后面可以接各种成分,但必须与上句的某个成分平行和对等。例如:
We don’t have enough room for another guest, let alone an entire family. 我们没有足够的空间容纳另一位客人,更不用说一家人了。
Her income was barely enough to maintain one child, let alone three. 她的收入养活一个孩子都几乎不够,更不用说三个了。
Billy can’t speak English, let alone write it 比利不会讲英语,更不用说写了。
Tom was hardly walking at the age of four, let alone running. 汤姆4岁时几乎还不会走路,更别说跑了。
I haven’t decided on the menu yet, let alone bought the food. 我还没决定吃什么菜呢,更不必说买好了。
