The old man had his left leg _____ ,but he had his tractors _____ day and night
A.hurting,working B.hurting,worked C.hurt,working D.hurt worked.
答案是C.第一个空懂的..第二个不懂..have 在这种句式的用法是咋样的?
还有一题
-Did you have anyone ____ the trees?
-Yes,I have had the trees _____ .
A.to water,water B.water,watered C.water,to be watered D.to water,watered.
这题答案是B.为什么第一空不是to water?
有人知道帮帮忙!!~~~

have+名词+doing
我们初二学过,类似于have problem doing sth
第二题have好像相当于let、make,
have sb. do sth记不清了,可能是这样吧

have这里做使役动词,后跟原形
第2空是被动用法

还有第一题额..第一题才是重点呐!!既然是使役动词了为啥答案是doing?
