We’ll need to buy a lot of things for our puppies.是不定式做宾语吗?

We’ll need(主谓） to buy a lot of things for our puppies（不定式短语作宾语）
不定式短语分析
to buy a lot of things for our puppies
= to buy our puppies a lot of things
可见：to buy 是接双宾语的.
语言点：
buy sb sth= buy sth for sb(注意这里不可以用to)
再问： 是指to buy a lot of things一起做宾语，还是分开来的？如to buy作宾语；a lot of things作宾语补足语。
再答： 你把我弄晕了 ：） 仔细看看我的解释。这里没有复合宾语，也就没有宾补
