ask
1.ask his name是“问他的名字”，ask his opinion是“问他的意见”，ask the way是“问路”，ask the time是“问时间”，但ask the price有时是“问价”，有时是“讨价”。I asked him the price是“问价”，He asked the price of ¥20是“讨价”。
ask（问）可以有双宾语，如I asked him his name和He asked me my opinion。
2.He asked me something是“他问我一个问题”，He asked me for something是“他向我要些东西”。
3.I asked him a question比I asked a question of him普通。I have a question to ask (of) you里的of可有可无。
4.'Are you sure of it?' he asked（问）(of) me里的of可有可无。I am afraid it is too much to ask（请求）of him里的of不可省去，偶尔用from。
5.ask和ask for都作“请求”解。ask通常用于无形的东西，如ask a favour，ask advice，ask permission和ask clemency。ask for用于有形的或无形的东西都可以，如ask for bread，ask for money，ask for a ticket，ask for help，ask for information，ask for leave，ask for pardon和ask for forgiveness。假使说出了那被请求的人，用了ask该在那宾语后面加上of和指人的词，用了ask for该在ask后面加上指人的词，如ask a favour of him和ask him for bread。ask a favour of him改作ask him a favour也可以，但ask用作“请求”解带有双宾语，那直接宾语只有favour，却不说ask him advice或ask him permission。
6.He asked about you是“他问起你”，He asked after you是“他问起你的健康情况（或生活情况）”，He asked for you是“他问起要见你（或跟你联系）”。
7.He asked me 'Will you go with me?' 是正常的英语。He asked me whether I would go with him也是正常的英语。He asked me, Would I go with him? 不是正常的英语，但这种结构在不很严谨的文字里时常见到。
8.ask（请求）后面可以接以that引导的从句，那从句里用shall或should或虚拟现在式，如I ask that he shall（或should）call this evening, I ask that he call（不用calls）this evening, I asked that he should call that evening和I asked that he call（不用called）that evening。
