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.

查看习题详情和答案>>A new study says one part of the human brain may become smaller as the result of a condition known as jet lag. Jet lag results from flying long distances in an airplane. People with jet lag may feel extremely tired for several days. They may also have problems thinking clearly and remembering.
Recently a researcher at the University of Bristol in Britain reported the findings of his jet lag study, which involved twenty young women who worked for international airlines. They had served passengers on airplanes for five years. These flight attendants flew across many countries and at least seven time zones. In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women spent five days or fewer in their home areas between long flights The other half spent more than fourteen days in their home areas.
The researcher took some saliva from the women's mouths to measure levels of a hormone(荷尔蒙) that increases during stress (紧张). He tested them to see if they could remember where black spots appeared on a computer screen. And he took pictures of their brains to measure the size of the brain's temporal lobes (脑叶).
It was found that the women who had less time between flights had smaller right temporal lobes. This area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction times on the visual memory test. And their saliva samples showed higher levels of stress hormones.
The researcher believes the brain needs at least ten days to recover after a long trip. He says airline workers told him their ability to remember got worse after working on planes for about four years. Other studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that controls memory.
Scientists say more tests are needed to study the effects of jet lag on the brain. They want to find out if too much jet lag could permanently (永久性的) affect memory.
According to the text, jet lag _________.
A. can cause difficulties in speaking
B. can make people feel tired for a few weeks
C. can be only found in flight attendants
D. can be caused by flying over several time zones
It can be inferred from the text that _________.
A. the conclusion is refused by many scientists
B. scientists fear that this research is not done properly
C. every scientific conclusion needs the support from many tests
D. the women who were examined in the research were not healthy
From the result of the research we can see that _________.
A. the women who have longer rest at home show better memory
B. the women who fly in short time have smaller right temporal lobes
C. the women who have longer flights fail the memory test
D. the women who rest more than 14 days produce less hormones
What is the subject discussed in the text?
A. The cause of jet lag. B. A story of a group of flight attendants.
C. The importance of having enough rest after flights.
D. A research about the effects of jet lag on the brain.
