吸煙有害健康。

healthy ?adj. ?健康的

keep healthy ?保持健康

5. although ?conj. ?雖然;盡管;即使

although=though,漢語中可以說“雖然……,但是……”,但英語中although/though不能與but連用。

8. however ?adv. ?然而;不過

She was ill. However, she still went to work.

表示“然而,可是”時,however必須用逗號與句子其他成分隔開。不僅能位于句首,而且能位于句中(注意前后使用逗號),甚至句末(注意其前也用逗號)。

However, he changed his mind later.

可是他后來改變了主意。

He hasnt arrived. He may, however, come later.

他還沒有到,不過他等會兒可能會來。
