  His life was devoted to the cause of justice .他为正义事业而献身。

  3.The bedclothes catch fire and the whole house may be burnt down.铺盖着火了,整个房子都可能烧掉。

  a. catch fire作“着火”、“起火”解,有动态的含义,(尤指意外地烧着,着火。)

  The house caught fire while we were away. 当我们外出时,房子着火了。

  The girl was standing too close to the fire and her dress caught fire. 那小姑娘站得离火太近了,衣服烧着了。

  除此之外,还有短语be on fire, set …on fire表示“烧着”、“着火”的意思,但be on

  fire有静态的含义,而set …on fire是“使……着火”、“放火烧……”的意思。例

  如: Look, the house is on fire. 瞧,房子着火了!

  The police caught the man who set the house on fire.警察抓住了放火烧那房子的人。

  b.动词短语burn down 作“烧毁”、“烧掉”解,主语一般是表示事物的名词。例如:

  The house burnt down in half an hour. 那所房子在半小时之内就被焚为平地。

  Don’t leave the gas on, or you might burn the house down. 别忘了关煤气,不然会把房子烧掉的。

  4.China produces one third of the world’s agarettes. 中国生产的香烟占全世界香烟的三分之一。

  请注意英语中分数表达法:

  除二分之一( )和四分之一( )分别由a(one)half和 a(one) quarter表示外,分数的构成通常是分子用基数词,分母用序数词。如果分子大于1,则分母用序数词的复数形式,如: (two thirds), (three quarters), (one half) (two sixths), (four fifths)

  5 .Every year, tobacco companies must persuade new people to start smoking agatettes.

  每年烟草公司要设法使一些不吸烟的人开始吸烟。

  句中的persuade是“劝说”、“说服”的意思,常用于persuade sb to do sth句型中,意为“说服某人干某事”与其相同意思的结构有persuade sb into doing sth .这时表达的意思是“某人已被说服干某事”;

  如果要想表达“说服某人干某事”这种愿望时,而某人未被说服,则多用try to persuade.例如:

  The salesman persuaded us to buy his product.售货员劝说我们购买他的产品(我们买了。)

  Who persuaded you to join this society?谁劝你加入的个团体?(他已加入了)

  How can we persuade him into joining us?怎么才能说服他参加我们的活动呢?

  The parents tried to persuade their daughter to change her mind, but they failed to .你父母试 图劝说他的女儿改变主意,但未劝说成功。

  6.The chance is that one smoker in four will die from smoking. 每四个烟民中就有一个可能因吸烟而死亡。

  在句中chance 作“可能性”解,既可作可数名词,也可作不可数名词。例如:

  The chances are a hundred to one that he will win. 他只有百分之一赢的可能性。

  Is there any chance of getting tickets for the perfornance ? 有可能得到这场演出的票吗?

  Chance作可数名词用时,作“机会”解。例如:

  you won’t get another chance of going there. 你没有再到那里去的机会了。

  Please give me a chance to explain. 请给我个机会让我解释一下。

  但chance作“偶然性”、“运气”解时,则为不可数名词。例如:

  Chance plays a big part in many board games.在许多棋类游戏中,大多靠碰运气取胜。

  It was chance that we met in Shanghai. 我们在上海相遇属巧合。

  chance还可作动词用,作“偶然发生”、“碰巧”解,这时用法上相当于动词happen,

  句型为chance to do …和It chanced that …。例如:

  She chanced to be in when I called.

  我打电话时碰巧她在家。

  It chanced that she was in when I called.

  7.In Britain, sales of agarettes have been reduced by 30% in the late ten years . 过去十年来,英国的香烟销售量下降了30%。

  句中的reduce为动词,作“缩减(体积、数量、程度、价格)”、“减小”、“减少”“降低”解。常与介词by或to连用,表示“减少了……”,“减少到……”。例如:

  The number of the students in each class should be reduced to 40.每个班的学生人数应减到40人。

  He reduced his weight from eighty to seventy kilos.他把体重从80公斤减少到70公斤。

  He reduced his weight by 10 kilos. 他体重减少了10公斤。

  Their wages have been reduced by 20%.他们的工资减少了2%。

  reduce的反义词是increase(增加),与by连用时,表示增加的程度;与 to连用时,

  表示“增到……”例如:

  The wages of the workers have been increased by 30%. 工人的工资增加了30%。

  The population of the country has increased from 1.2million 10 years ago to 1.8million mow .

  那国家的人口从10年前120万已增加到现在的180万。

  8.In the 16-19 age group, 32% of women smoke, compared to 28% of men. 在16-19岁这个年龄组里,有32%的妇女吸烟,而吸烟的男子为28%。

  句中的compare to /with是一个固定的短语,作“……和……比起来”、“与……相比”
