Key sentences
1 Nearly finished! 快做完了。
本句是口语省略句，其中finished 是形容词，作表语， 表示“完成来的； 结束了的。” 全句是“I am nearly finished.”
All that is finished now. 所有那一切现在都结束了。

此句是一个好有宾语从句的复合句。而在宾语从句中又有一个because引导的表语从句。注意suppose 的用法类似于think。变否定句时应该否定主句； 当变反意疑问句时，当主语是第一人称时应根据从句来变， 若是其他人称应根据主句来变反意疑问句。
I don’t suppose he will come today. 我猜想今晚他不会来了。
We don’t suppose Tom will come, will he 我们认为汤姆不会来， 对吗？
3 Is life today better or worse than it was 50 years ago

---- I like apples.
----Which would you like, red or white
