题目

【the result of the exam was not made_____until last week.】
1】
the result of the exam was not made_____until last week.
这里为什么用known 不用to know呢?
make被动式不是要+to么?
2】
if you can't sleep well ,try___some milk before you going to bed.
为什么用drinking不用to drink,还有为什么是before you going to bed不是befoer you go to bed?
3】
she looked___at the news and looked ___at the picture of her ded son
第一个是sad,第二个是sadly,
会多少答多少吧,

答案

1.这是被动语态,主动语态是：sb.made the result of the exam known,意指“让考试结果被知道”,所以变成被动后,就成了the result was made known.如果原来是make sb.do变成被动后才是sb.be made to do
2.try to do指尽力做某事,努力做某事
try doing 指试着做某事,句中指试试睡前喝牛奶
至于before you going to bed肯定是错的,要么说：before you go to bed要么说 ：before going to bed
3.第一个look是连系动词,表示看上去,后接形容词；第二个look是实意动词,意为“看”,用副词修饰.
句意为：听了消息,她看上去很悲伤,难过地看着她死去儿子的照片.
