一、句子中出现下列单词或短语时，往往表示两个相反的或不同的 意义

even， but， even though， however， yet，in spite of，despite， although， instead， on the Other hand， on the contrary⋯⋯

例如：

1. It was a bitter cold night，but the old man wore alight jacket and his head and hands were bare.

2. Although most of his working hours were spent inthe laboratory， he managed to find some time each day forhis children.

3. I’d like to go with you； how ever， my hands are full.

4. Why do you think we can’t change your note？on the contrary we can.

有时句中出现上述这些词时，并不一定表示两个句子的意义是相反的， 而只是给出一个相反意义的线索，真正的意义还需要读者去猜。

例如：Columbus thought he had reached the East Indies，but he has wrong.

“he was wrong”这句表达的意义并不是和前一句相反，而是给出一个线索，即哥伦布的想法是错误的。真正的意思为“哥伦布去的地方不是印度。”再如： Mr Johnson was rich and famous. Yet he wasan

unhappyman.

前一句说 Mr Johnson 富有而且著名，意味着他应当高兴（He should have been happy）。后一句说他是一个不快乐的人，而真正的含义则应该是“他并不快乐（He wasunhappy）”。
