选A 　　　　Let's buy some chicken for lunch 让我们买些鸡肉做午饭吧.let 是使役动词,后面跟动词原形.
选 A　How much （are） these pants?（They're） 45yuan
填什么A are they're B are it's C is it's D are it's　　　　因为pants　是裤子的意思,是复数,所以用　are　　,　后面相对应的就用they＇re　how many do you want?fourteen A banana B apples C tomato D watermelonB apples， how many 后面加可数名词的复数形式。 你到底有多少问题啊，可否一下子问了？不然这样追问的话，我是要扣分的啊。
