填空：
1.models 模型
the Madame Tussauds wax museum in London 伦敦杜莎夫人蜡像馆
其内当然有很多蜡像“模型”了!
改变句型：
1.When I passed his house,he was playing the piano.
=I saw （him playing）the piano when I passed his house.
=I saw (he's playing) the piano when I passed his house.
第一种变化采用“感官动词see + 宾语him + 宾语补足语playing”结构；
第二种变化采用“及物动词see + (that) + 宾语从句”结构,其中he's playing = he was playing.
2、Everybody knows that the earth turns around the sun,(don't they)/(doesn't he)?
Everybody做主句主语时,且主句谓语动词并不是think/believe等时,其反意疑问句以主句为准,可以用they或he代替everyong均可.
