【指点迷津】
单元重点词汇点拨
1. reason vi . 评理；劝说；推断为；说服
I reasoned that he was lying . 我断定他在撒谎。
〖点拨〗reason sb into doing = persuade sb into doing = persuade sb to do说服某人干……。reason sb out of说服某人不干……。
另外要注意当reason作名词时常用于：The reason (why) … is that …。the reason for sth和 the reason to do sth是“……的理由。”
The reason (why) he got ill was that he didn’t pay attention to his health .
The reason why we don’t trust him is that he has often lied .
2. worthwhile值得的 ；值得花费时间和金钱的
She was offered a worthwhile job .
〖点拨〗It is worthwhile + to do (或者 –ing ) 。如：It’s worthwhile visiting the museum . = It is worthwhile to visit the museum .
注意下面的“值得”表达：be worth doing ; be worthy of being done = be worthy to be done 。
如：The article is worthy of careful study . = The article is worthy of being studied carefully . = The article is worthy to be studied carefully . = The article is worth studying .
