初二英语语法点
可是我不懂
She has a new bag-Does she have a new bag?
we like animals- Do we like animals?
为什么SHE开头用DOES回答 WE开头用DO回答
还有问下
buy spend pay cost take 的那个语法点.
比如说 buy sth for some money
spend some money on sth
pay some money for sth
其他的是怎么样的

第一个问题：
因为she、he、it都是第三人称单数,所以在一般现在时中都要用dose作为助动词,像其他的第一人称单复数、第二人称单复数以及第三人称的复数形式的代词都要用助动词do.
第二个问题：
buy、spend、pay、cost和take都有“花费”的意思.区别在于：
buy sb sth=buy sth for sb给某人买某物,是这五个单词中唯一一个可以跟双宾语的
spend：sb spend some time/money on sth 某人花多少钱买某物/花多少时间多某事
sb spend some time （in）doing sth 某人花多少时间在某事上面,in可以省略
pay：sb pay some money for sth 某人为某物付多少钱
pay some money for sb 为某人付钱
pay back 还钱
pay off 还清
cost：主语一定是物,sth cost sb some money 某物花了某人多少钱
take：有一个固定句型：it take sb some time/money to do sth 做某事花了某人多少时间/多少钱
1.第三人称单数，疑问句和否定句用组动词DOES,第三人称复数和一、二人称疑问句和否定句用组动词DO.
2.Sth. cost sb. some money
It takes sb. some money to do sth/on sth/on doing sth
1.因为SHE是第一人称单数，WE是第三人称复数，请记住这些对你记这些有重要作用！SHE,HE,IT是用助动词DOES！THEY,WE,I,YOU,用助动词DO
因为她是第三人称单数，所以用Does来问,而we第一人称单数所以用Do来问
