     A new weapon is on the way in the fight against smoking in Europe. Soon when smokers buy cigarettes,

they might see a shocking photo of a blackened lung or a cancer patient staring back at them from the packet.

     Some boys may think of smoking as cool and sexy. Their friends won't agree when they see their packets

of cigarettes lying on the table.

     The European Union announced on October 22, that it had chosen 42 photos that showed the damage

cigarettes could do to the body. It called on member nations to put these pictures on packets to discourage

young smokers.

     To catch the attention of teenagers, the special packets warn of long-term medical dangers, like cancer.

Short-term effects, like bad skin, are also on the list.

     "The true fact of smoking is disease, death and horror. That is the message we should send to the young,"

said David Byrne, an EU health official. "Hopefully these pictures will shock students out of their love for

cigarettes."

     The EU head office hoped the pictures would work better than current written warnings on packs of

cigarettes. The warning included "smoking kills" and "smoking can lead to a slow and painful death".

     So far, Ireland and Belgium have shown interest in the photos. Canada has used similar pictures and

warnings on cigarette packs since 2000. The country has recently seen a fall in the number of smokers.

     According to studies, smoking is the single biggest cause of avoidable death in EU. Every year more

than 650,000 smokers die, more than one person a minute.

1. What would be the best title for the text?

A. New Ways to Stop Smoking.

B. Pictures to Shock Smokers.

C. New Packets of Cigarettes.

D. Dangers of Smoking.

2. Which of the following is NOT the true fact of smoking?

A. Disease.

B. Death.

C. Horror.

D. Happiness.

3. We can learn from the text that _____.

A. the EU countries have put the new warning method into practice

B. only a small number of the EU countries have used the new warning method

C. the new warning method has worked in some EU countries

D. countries in the EU still use the old warning method

4. Which country is most successful in stopping smoking?

A. Ireland.

B. Belgium.

C. Canada.

D. EU.

5. The underlined sentence in the last paragraph suggests that _____.

A. it's hard to stop smoking in EU

B. deaths caused by smoking could have been avoided

C. smoking is the biggest cause of deaths in EU

D. EU has the largest number of deaths caused by smoking

世界市场的建立是一个漫长的过程,它对世界各个国家与地区产生的影响是不同的。阅读下列材料:

材料一16世纪中期至17世纪中期,美洲生产的白银30000吨;日本生产的白银8000吨;两者合计38000吨;最终流入中国的白银在7000至10000吨之间。因此在那一百年间,中国通过“丝—银”贸易获得了世界白银产量的1/4至1/3。

——樊树志《国史十六讲》

1843年与1858年中国进口棉花及棉纺织品税率比较表

洋货入中国则输半税,土货出外洋,则加重征。资本纵相若,而市价则不相同,洋货可平沽而土货必昂其值,颠倒错紊,华商安得不困,洋商安得不丰。

——郑观应《盛世危言》

材料二1814~1835年,英国输往印度的棉布增加了62倍,同期印度输往英国的棉布减少了3/4。1840年英国下议院特别委员会询问英国商人麦尔维尔“英国工业是不是已经取代了印度的手工业”时,后者说:“是的,在很大程度上。”“从什么时候开始?”“我想,基本上是从1814年起。”“英国工业排挤了印度工业是不是说印度现在的供应主要依靠英国厂家的商品?”“我认为是这样……我毫不怀疑,他们的重大灾难主要是由于英国工业打乱了印度的工业。”

——摘编自汪熙《约翰公司——英国东印度公司》

材料三1573年,对后来现代化至关重要的两个观念上的变化已经发生:文艺复兴和宗教改革,此外还有一个技术性的工业革命,现代科学和现代工业推动了今天以西方为主体的世界体系。

中国这种从传统社会到近代社会的转型,在明末已经开始,这一转型具有划时代的意义。中国市场迅速扩张,在全国市场形成以后,实际上就是发展到世界市场上去,这是一个必然的结果,也就是说中国的白银货币化直接影响了世界市场的建立。

材料四1842年中英《南京条约》规定:“英国商民居住通商之广州等五处,应纳进口、出口货税、饷费,均宜秉公议定则例,由部颁发晓示,以便英商按例交纳。”

1824年,英普条约规定两国船只在彼此港口中所征关税平等,法国拿破仑三世统治时期,奉行自由贸易原则,全面地、大幅度地降低商品进口关税,废除第一帝国以来的关税保护政策;1860年以后,法国与英国、比利时、德国等签订一系列自由贸易条约,将本国的经济完全纳入世界市场。

请回答:

根据材料三指出近代世界市场形成和发展的因素。
