Unit 9 重点句子解析
1. I guess that people who know how to communicate well with others are happier and more satisfied with their lives.
这句话中的I guess 是主句，后面是that引导的宾语从句；宾语从句中的主语是people，后面又是who引导的定语从句；句式be satisfied with 与be pleased with 同义，意为“对……感到满意”。如：
I think the radio that is made in Shanghai is the best. 我想上海生产的收音机是最好的。
Are you satisfied with what I said? 你对我说的话感到满意吗？
2. We used to study and play together, but ever since last Friday, she hasn’t spoken to me.
used to的意思是“过去经常”，后加动词原形，它可以用于各种人称之后。如：
He used to live in this small village. 他曾经住在这个小村子里。
与used to相似的句式是be used to，它的意思是“习惯于”，后加名词、代词、V-ing形式作介词宾语，并且它有各种时态的变化。如：
She is used to the life here. 她习惯了这里的生活。
