As A/H1N1 continues to spread, experts from the Centers for Disease Control to the World Health Organization to neighborhood doctors are calling on the people to practice smart flu prevention techniques. Here are some tips to keep body improved and immune（免疫）system ready to fight infection.
Wash Your Hands
And wash them often, in hot soapy water, and for the amount of time it takes you to sing “Happy Birthday” twice.
Get Enough Sleep
This means slightly different things to different people, but try to get 8 hours of good rest each night to keep your immune system in top flu-fighting shape.
Keep Hydrated
Drink enough water each day to clear poisonous matter from your system and keep up good moisture（湿度）production in your body.
Eat Immune-Improving Foods
Keeping you body strong and ready to fight infection is important in flu prevention. Fatty foods can slow your metabolism（新陈代谢）, make you feel inactive, and weaken your immune system. So stick with whole grains, colorful vegetables, and vitamin-rich fruits.
Avoid Alcohol
Alcohol is likely to decrease your resistance to infections and further damages the immune system. So avoid alcoholic drinks to keep your immune system strong.
Proper exercise-for example walking for 30-40 minutes 3-4 times a week-supports the immune system by increasing circulation, oxygenating the body, removing poisonous material through sweat, and reducing tension and stress. So get moving!
Avoid Contact with Sick People
If you’re coughing or sneezing, cover your mouth(and then wash your hands),and if you have to be around someone who is sick, try to stay a few feet away from them and avoid physical contact.
Know When to Get Help
A/H1N1 can look like regular flu, so don’t feel like you necessarily are infected if you’re exhibiting flu-like symptoms（症状）. But do go to your doctor if you live in an area where there are recorded cases, or if your symptoms are very serious.

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.
68．What would be the best title for the text?
A．New Ways to Stop Smoking. B．Pictures to Shock Smokers.
C．New Packers of Cigarettes. D．Dangers of Smoking.

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

A recent survey of teachers found that an unhealthy passion with celebrity culture is having a negative impact on British students’ studies and it discovered that celebrity couple, the Beckhams, are the favorites among most students. Many students are ignoring building their own careers to seek a chance at fame instead, the Association of Teachers and Lecturers (ATL) survey found.
Almost two-thirds of teachers said sports stars were the type of celebrity many pupils wanted to follow while more than half of students wanted to be pop stars.
The survey said the celebrities that students aspired to mostly were David and Victoria Beckham who live in Los Angeles now. Soccer player Beckham is on the top of the survey while in second place, with almost a third of the survey’s votes, was his 33-year-old pop star wife.
Almost half of the 300 teachers surveyed said pupils tried to look like or behave like the celebrities they most admired, with some girls even dressing "unsuitably".
"We are not surprised about the influence of celebrity culture in schools —it reflects the current media passion with celebrities and the effect of celebrity culture on society as a whole," ATL general secretary Mary Bousted said in a statement.
"Celebrities can have a positive effect on pupils. They can raise pupils’ aspirations and desires for the future. However, celebrity culture can spread the idea that celebrity status is the greatest achievement and reinforce the belief that other career choices are not as valuable," said one primary school teacher. "Too many of the pupils believe that school success is unnecessary, because they will be able to get fame and fortune quite easily through a reality TV show."
The story mainly tells us that ______.
A. the Beckhams are mostly admired in Britain
B. most students think that being pop stars is more valuable than other career achievements
C. the celebrity passion has a harmful impact upon British students’ studies
D. a survey was made recently about the popularity of the stars
According to the survey, Victoria Beckham ______.
A. is a pop star most students admire
B. goes in the second place of the celebrities admired
C. won two-thirds of the votes
D. lives in New York now
Why does the author mention that pupils tried to look like or behave like the celebrities they most admired, with some girls even dressing “unsuitably”?
A. The pupils think it interesting to pretend to be the celebrities.
B. The behavior or the dress of celebrities can be followed as examples.
C. The author wants to show the negative influence these celebrities had on the students.
D. The author just wants to show being pop stars is very valuable to the students.
What is not TRUE according to the story?
A. Celebrities can’t have positive impact on the students.
B. Beckham and Victoria are husband and wife.
C. The so-called celebrity culture does harm to the pupils’ ideas about achievement.

查看习题详情和答案>>A "lost tribe" that reached America from Australia may have been the first Native Americans, according to a new theory.
If proved by DNA evidence, the theory will break long established beliefs about the southerly migration of people who entered America across the Bering Strait, found it empty and occupied it.
On this theory rests the belief of Native Americans to have been the first true Americans. They would be classified to the ranks of escapee, beaten to the New World by Aboriginals (土著人) in boats.
To a European, this may seem like an academic argument, but to Americans it is a philosophical question about identity (身份), Silvia Gonzales, of Liverpool University said .
Her claims are based on skeletons found in the California Peninsula of Mexico that have skulls (头骨) quite unlike the broad Mongolian features of Native Americans. These narrow-skulled people have more in common with southern Asians, Aboriginal Australians and people of the South Pacific Region.
The bones, stored at the National Museum of Anthropology (人类学) in Mexico City, have been carbon-dated and one is 12,700 years old, which places it several thousand years before the arrival of people from the North. "We think there were several migration waves into the Americas at different times by different human groups," Dr. Gonzales said． "The timing, route and point of origin of the first colonization of the Americas remains a most contentious topic in human evolution."
But comparisons based on skull shape are not considered conclusive by anthropologists, so a team of Mexican and British scientists, backed by the Natural Environment Research Council, has also attempted to take out DNA from the bones. Dr. Gonzales declined yesterday to say exactly what the results were, as they need to be checked, but indicated that they were consistent（一致） with an Australian origin.
It is generally considered that the first Native Americans came from _____.
A．North Asia B．Australia C．South Pacific D．South Asia
The skeletons found in the California Peninsula of Mexico have _____.
A．the broad skull shape
B．the narrow skull shape
C．different features of Aboriginal Australians
D．the same features of Native Americans
The underlined “contentious” is similar in meaning to “_____”.
A．likely to cause great interest B．difficult to solve
C．well-known to all D． likely to cause argument
Which of the following statements is true according to the text?
A．Research on skulls can draw an exact conclusion.
B．DNA tests have proved the fact that the first Native Americans came from Australian.
C．Scientists are still not sure about the origin of the Native Americans.
D．People began to enter America across the Bering Strait about 12,700 years ago.
