4.The electrician explained to us _____ electricity played an important part in our daily life.(  )
A.what was it thatB.why was it that
C.what it was thatD.why it was that

分析 那位电工向我们解释了为什么电力在我们的日常生活中起着重要的作用.

解答 答案:D.
本句中explained后面跟的是一个宾语从句,宾语从句中必须使用陈述语序,所以排除A和B两项;根据句意"为什么电力在我们的日常生活中起着重要的作用"可知,从句中强调的是原因,所以用why来引导强调句型的特殊疑问句型;所以排除C;故选D.

点评 注意:名词性从句中如果含有疑问句,疑问句的语序必须使用陈述语序.

Now it is not allowed to set of firecrackers in big cities on festivals.Now it is not allowed to set of firecrackers in big cities on festivals.Some people are against it.But I am for the idea.
Some people think setting off firecrackers is a traditional way to celebrate important festivals,especially the Spring Festival.It can show people's happiness and the festive mood.And people can enjoy the beautiful scenery of fireworks.
On the other hand,as we all know,setting off firecrackers may cause a lot of trouble,It may bring big fire and air pollution.And it will do harm to people's eyes and hearing.If firecrackers are not set off correctly they can injure or disable people,which will bring great sorrow to the family.
From these we can see there are more disadvantages,so I approve of not setting firecrackers,and we should seek other ways to show our happiness..
