1.As a student,you should never smoke. as为介词,意为“当作,作为”。 2.Smoking is bad for your health.

◆本句为动名词作主语的句子。当动名词作主语时,谓语动词用单数形式。动名词作主语的句子可改为用动词不定式作主语,此时

常用it作形式主语,而将真正的主语——动词不定式放在句末,即“It is+形容词或名词+to do sth.”。

◆be bad for意为“对……有害”,其反义词组为be good for,意为“对……有益”。 3.It can cause diseases of the heart and lungs.

disease为名词,意为“疾病”,是用以指各种病的术语,特指严重的,长期的疾病,如肝病、心脏病等。

【拓展】 (1)sickness多用来指恶心、呕吐之类的疾病,这种疾病大多由外因引起,且病痛时间较短。

(2)illness主要指因人体内部的虚弱或失调引起的疾病,且病痛时间较长。 4.Every year,millions of people around the world die as a result of smoking. ◆millions of表示模糊概念,意为“数百万的”,此时million用复数形式,且与of连用。 We plant millions of trees every year. 每年我们种植数百万棵树。

【拓展】 (1)当million前有基数词,表达确数时,无论基数词是什么,million永远都用单数形式。

three million三百万

(2)与million用法相同的单词还有hundred,thousand和billion。

◆die在这里为不及物动词,意为“死,死亡”,其过去式和过去分词都为died,现在分词为dying,形容词为dead/dying,名词为death。 The old man died of cancer yesterday. 昨天这位老人死于癌症。

The doctors have saved the dying man. 医生们已经救活了那个垂死的人。

◆as a result of由于,因为,相当于because of,后面接名词或代词。 He was late as a result of the heavy snow. 由于大雪,他迟到了。

5.If you smoke,you harm yourself,and you’re also harming the people around you with your second-hand smoke.

harm在本句中为及物动词,意为“伤害,损害”。harm oneself意为“伤害某人自己”,与hurt oneself同义。

6.Whenever someone offers you a cigarette,you should always say no.

◆whenever为连词,意为“无论何时,在任何……的时候”,相当于no matter when,引导 让步状语从句。

【拓展】 whatever=no matter what无论什么 wherever=no matter where无论哪里 however=no matter how不管怎样

◆offer为及物动词,意为“(主动)提供,给予”,其后可接双宾语,即offer sb. sth.,相当于offer sth. to sb.,意为“向某人提供某物”。 【固定搭配】 offer to do sth.主动提出做某事 7.Don’t take that risk.

risk为名词,意为“危险,风险”。take a risk冒险。take the risk of doing sth.意为“冒险做某事”。

A good pilot never takes a risk.

优秀的飞行员从来不冒险。

8.Once you get into the habit of smoking,it’s not easy to give it up. ◆get into the habit of为固定短语,意为“习惯于……,养成……的习惯”。

I get into the habit of listening to music every night.我养成了每天晚上听音乐的习惯。 ◆give up为固定短语,意为“放弃”,若宾语为人称代词,则须放在give与up之间。give up doing sth.意为“放弃做某事”,give up不能接动词不定式作宾语。 He gave up smoking at last. 最终他戒掉了烟。

9.Stay away from cigarettes and you can live a long,healthy and happy life. ◆stay away from为固定短语,意为“离开,远离”,与keep away from同义。 Why did you stay away from school? 你为什么没上学?

◆live a…life表示“过……的生活”。 live a happy life过幸福的生活 live a hard life过艰苦的生活
