The idea __ a good one,and I'll think about it. The life we

第一空：seems 或 sounds like.只填sound,应该欠妥的,虽然不敢说百分之百错.sound后面通常只跟形容词作表语的.
第二空：has changed.the life作主语,不可数.we were used to作the life的定语,to后面的宾语其实就是主语the life.这句话的意思是：我们过去所习惯的生活,自1992年以后已经发生了巨变.另外,这句话的同义句为：The life we were used to has been great changes since 1992.
第三空：How great ,如果想填what great,应该写成：What a great sportman O'Neal is!
另外,回答一下你的追问：
What 修饰名词,奥尼儿是名词哦.为何要用how呢?是不是应该how great the O‘Neal is!
how修饰动词或者形容词.《我这样理解对吗?》
答：（1）奥尼儿不是名词,相当于人称代词,前面是不可以加冠词的.（2）how修饰形容词或副词,它可从来不修饰动词的呵.
我是席老师,有问题,你尽管继续问,

1.is
2.has changed
3.How great How+形容词或副词+主语+be/谓语动词。

The idea is a good one,and I'll think about it. The life we were used to has changed greatly since 1992.
How amazing O'Neal is!第一空 sounds 第二空 being change 第三空 What great 这样对吗？为什么呢？第一空...
