7In order to avoid (confuse)-------,all the bottles are labe

我觉得我的答案应该没有什么问题.第8题肯定不是left,一定是leaving,除非是...,and left 4 children with her.
7、In order to avoid confusion,all the bottles are labeled.为了避免混淆,所有的瓶子都贴上了标签.confusion,名词,avoid后面可以加名词或者动名词（-ing）,但我觉得这里confusion更合适些.前半句的意思其实就是In order to avoid people getting confused.
8、Her husband died in the war,leaving 4 children with her.leaving 4 children with her是动名词做结果状语,指她丈夫去世产生的结果.再举个例子：He turned off the lamp,(therefore) seeing nothing.他熄了灯,什么也看不见了.
9、Have you finished doing your homework?finish+doing sth.固定搭配
10、I was sleeping when the telephone rang loudly.电话响起时,我正在睡觉.
