双宾语的用法有哪些
改为被动语态什么时候用by、for和to？
改为被动语态什么时候用by、for和to？
含有双宾语的动词在变为被动语态时，有以下三种情形：
一、有些双宾动词(如award, buy, give, leave, lend, offer, pay, show, teach, tell等)在变为被动语态时，既可把间接宾语(指人)变为被动语态的主语，而把直接宾语(指事物)保留下来(称为保留宾语)，也可把直接宾语(指事物)变为被动语态的主语，而把间接宾语改为介词to 或for引起的状语(到底用to还是for，与所搭配的动词有关)。
比较：
He gave her some money. 他给她一些钱。
→ She was given some money.
→Some money was given to him.
He bought her a watch. 他给她买了一快表。
→ A watch was bought for her.
→She was bought a watch.
二、有些双宾动词(如bring, do, make, pass, sell, send, sing, write等)通常用直接宾语(指事物)作被动语态的主语，而将间接宾语用作保留宾语(其前根据情况用介词to或for)：
Father made me a doll.
→ A doll was made for me.
He wrote her a letter.
→ A letter was written to her.
三、有些双宾动词(如answer, deny, envy, refuse, save, spare等)通常用间接宾语(指人)作被动语态的主语，而将直接宾语用作保留宾语：
He answered me that question.
→ I was answered that question by him
provide可以直接跟双宾语吗？
不能，
有 provide sb with sth,
provide sth for sb
没有provide sb sth这个用法，
但offer就有offer sb sth这个用法。
consider是双宾语吗？
对的。consider sb sth是基本用法，具体内容如下。
双宾语由直接宾语和间接宾语组成。直接宾语是谓语动词的承受者，间接宾语表示谓语动作的方向（对谁做）或动作的目标（为谁做），间接宾语紧接在谓语动词后，但它不能单独存在。它和直接宾语组成双宾语。
They gave him a watch.
这里的him是间接宾语，a watch是直接宾语, 这种间接宾语和直接宾语同时出现的情况叫双宾语.
