1)We listened eagerly, for he brought news of our families. 2)We listened eagerly for he brought news of our families. 第1句中,连词for前加了逗号,第二句没有。两种表达有什么区别?
want doing有没有想持续现在这个动作的意思。比如:我想在室外一直呆到晚上(现在就在室外)。这个是I want staying
outdoors until night.还是I want to stay
outdoors until night.是不是因为现在已经在室外了,所以只能用doing。
