　　 Ann is very smart. She always knows the answers to all the teachers' questions.

　　 Ann很聪明。她总是能回答老师们所有的问题。第二句是对第一句的补充说明，一个能回答老师们所有问题的女孩一定是很"聪明"的。

　　 She is usually prompt for all her classes but today she arrived in the middle of her first class. 她一般都是准时上课，但是今天第一节课上了一半她才到。

　　 but一词表示意思的转折，因此but前后的意思应是相反的。后半句的意思是她今天在"第一节课上了一半时才来"，由此反向推断，可得出她平时一向 "准时"的结论。

We like our new house because it has a few elms in the back yard that will give us shade and keep the house cooler.

我们喜欢新家，因为在它的后院有几棵榆树给我们遮阴，使得房子凉爽。

　　 通过elms具有能给房子遮阴、使房子凉爽的作用，我们不难猜出elms是一种树。

　　 We are glad that we live near the sea because we love to eat flounder.

　　 我们非常高兴住在海边， 因为我们非常爱吃比目鱼。

　　 这句话如果只看后半句，很难判断"flounder"的意思，而从前半句所提供的处所“the sea"，则可推断出flounder是一种鱼或水产品。

　　 I did not have a roll on my plate, but I do not like bread very much anyway.

　　 我盘子里没有面包圈，反正我也不喜欢吃面包。
