However, bird flu is a completely different story.
Ten years ago, the H5N1 bird flu swept across 15 countries, including China, with sufferers reporting chest pain, difficulty breathing, fever and severe coughing. More than 600 people were infected, and about 60 percent died. Now another type of bird flu hit Shanghai and three neighboring provinces, and this time the virus is called H7N9. By the afternoon of April 11, the new virus had taken nine lives out of 35 infected, according to Xinhua News Agency.
The“H”and“N”in the virus’ name refers to two kinds of proteins on the surface of the virus. Any change of the numbers of the two proteins indicates a new mutation(变异). Most of the mutations only affect birds, such as chickens and pigeons, and don’t normally spread to humans. But once they do, the results can be disastrous.
“Any time an animal influenza virus crosses to humans, it is a cause for concern, ”Malik Peiris, virologist(病毒学家)at the University of Hong Kong, told Nature magazine. Take the SARS epidemic(传染病)10 years ago as an example. The virus behind the disease is thought to have jumped to humans from animals. The virus was a complete“stranger”to human bodies, which hadn’t developed an immunity against it.
But there is something more about the new H7N9 bird flu. Unlike the H5N1 bird flu, which causes severe sickness in birds, the H7N9 has been evolving under the radar(悄悄地)since it travels between birds without causing noticeable illness. That makes it difficult to keep track of the disease.
The good news is that there’s so far no sign that the virus is spreading from person to person. But since there is no vaccine for the disease yet, the World Health Organization recommends that you wash your hands after meeting with sick people and before and after you eat or prepare food, and they also suggest avoiding contact with birds or their eggs.
小题1:Which of the following statements is TRUE according to the text?
A.The H5N1 bird flu turned out to have something to do with the SARS epidemic. |
B.More than 600 people across the world died from the H5N1 bird flu ten years ago. |
C.Most of the mutations of the proteins in the bird flu virus are harmful to both birds and humans. |
D.The name, H7N9 bird flu, shows that there have been new mutations of the proteins in the virus. |
A.introduce where the SARS virus came from |
B.inform us of the harmful effects of the SARS epidemic ten years ago |
C.show the horrible effects an animal influenza virus can have once it spreads to humans |
D.compare the differences between the SARS epidemic and the H7N9 bird flu |
A.It can cause severe sickness in birds. |
B.It can spread from person to person. |
C.It affects a greater number of birds. |
D.It doesn’t sicken birds and thus can spread unnoticed. |
a. To get vaccinated for the disease.
b. To keep away from birds and their eggs.
c. To stop eating chickens and ducks.
d. To avoid meeting with sick people.
e. To wash hands thoroughly and regularly.
A.a, b | B.c, d |
C.b, e | D.a, e |
答案
小题1:D
小题2:C
小题3:D
小题4:C
解析
小题1:选D。细节理解题。A项文中没有提及, B项提到的600多人是感染the H5N1 bird flu的人数, 死亡人数为这一人数的60%, 也就是不到400人; 由第四段的“Most of the mutations only affect birds, such as chickens and pigeons, and don’t normally spread to humans. ”可以推知C项不对; 由第四段的“Any change of the numbers of the two proteins indicates a new mutation. ”可推知D项正确。
小题2:选C。推理判断题。这里列举SARS的例子是为了说明本段首句谈到的“Any time an animal influenza virus crosses to humans, it is a cause for concern”, 而本段又是进一步说明上一段最后一句话“But once they do, the results can be disastrous. ”, 所以C项为正确答案。
小题3:选D。细节理解题。由倒数第二段可知, H7N9禽流感与H5N1禽流感不同的是它不会在禽类间导致明显的疫情, 这使得它的传播不容易被及时发现, 故答案为D。
小题4:选C。细节理解题。由最后一段可知, 专家建议人们勤洗手, 尽量避免接触禽类以及禽类下的蛋, 所以C项为正确答案。最后一段提到了现在还没有针对H7N9禽流感的疫苗, 故a不对。c, d文中没有提及。

The movie was made by American artist Jonathon Keats. It consists of Italian skies recorded over two months and made into a six-minute-long movie. The film shows the clear dawn(黎明), high clouds, amazing dusk and then beautiful night. The movie has no sound and the plants, of course, do not applaud. But Stephen Squibb, a professor from Harvard University, said these plants could benefit from it—the light of the movie keeps them alive because they can continue the process of turning light into energy.
“I realized there was a much larger audience—plants—that were not being serviced, ”Keats said. “I wanted to provide plants with entertainment that companies such as Disney provide for humans. ”Meanwhile, Keats also wants to explore plants’ sensibilities(敏感性)further. He plans to open a“restaurant for plants”at a Californian museum.
One visitor, photographer Abbas Ebrahimi, admired(羡慕)the green audience, “Plants are better than us. We die and go, while in spring they come back each time. ”But when talking about the movie, he said after thinking for a few minutes, “It doesn’t mean anything to me at all. It’s just about light. For some people, it might mean something. ”

Conductor Alan Gilbert was nearing the end of Mahler’s Ninth Symphony(交响乐) when the interruption began. As eh New York Times writes, the symphony, “contains some of the most spiritual and peaceful music ever written.”
As the cell phone continued to ring, the iPhone’s signature ringtone, Gilbert stopped the entire performance. And yet shockingly the phone continued to ring. “Nothing happened,” Gilbert told the Times, “Nobody was to blame for it. It was unbelievable.”
Gilbert said minor cell phone interruptions have become common and rarely interfere with a live performance. The Philharmonic does what it can to remind to audience to turn off their cell phones before the performance begins. But the audience and performers stood by in astonished silence as Gilbert asked the offender(肇事者) to silence the phone, only to hear it continue.
Mr Gilbert said audience pointed out two people sitting where the sound was coming from. “They were staring at me firmly,” he said of the couple. Eventually, the man put his hand in his pocket and the ringing stopped.
The conductor said he asked the man if he was sure the phone was quieted. “Then he nodded his head,” Mr Gilbert said.
People in the hall had been shouting for the sound to stop. Mr Pelkonen reported that they yelled: “Thousand-dollar fine!” “Kick him out!” “Get out!”
Once the phone was finally silenced, Gilbert apologized to the audience. They responded with cheers and applause(掌声). And the performance continued.

In addition,great numbers of animals were killed by the fires that bumed out of control. The fires were driven by high winds,moving as many as ten miles a day.Many small animals died in the flames.The fires’ rapid advances gave the wildlife little chance to escape. Even today,few of these small forest animals have returned to live in the park. In the years immediately following the fires,the numbers of visitors declined rapidly.No one was interested in seeing a blackened and treeless park on vacation.Yellowstone had previously been famous for its amazing views and unique geological formations such as the geyser Old Faithful. But now its reputation as America"s wonder is damaged permanently.

But now 400 organizations in the UK,from playgroups to the National Health Service,are encouraging children to have some“wild time”.They want kids to swap at least 30 minutes of watching TV or playing computer games for time playing outside.Activities such as building dens, climbing trees, rummaging for conkers and playing hide and seek are just some of the things kids can do. Even if they live in a city,they can go on adventures in the garden or the park.
Children often need a helping hand from mum and dad.They need to be shown what to do and where to go.Andy Simpson from National Health Service says,“We want parents to see what this magical wonder product does for their kids’ development,independence and creativity,by giving wild time a go”.
So despite the complicated world that young people grow up in now,it seems that going back to basics and experiencing“nature’s playground”is what modern children need.David Bond from Project Wild Thing says,“We need to make more space for wild time in children’s daily routine,freeing this generation of kids to have the sort of experiences that many of us took for granted”.
This might sound a bit old fashioned to you or maybe,like me,it’s made you think about sticking on your boots,getting outdoors and reliving your childhood.There’s no age limit on enjoying yourself!

Lead researcher Omri Gillath said the judgments were based on the style,cost,color and condition of someone’s shoes.In the study,63 University of Kansas researchers looked at pictures showing 208 different pairs of shoes worn by the study’s participants.Volunteers in the study were photographed in their most commonly worn shoes,and then filled out a personality questionnaire.
Some of the results were expected:People with higher incomes most commonly wore expensive shoes,and flashier shoes were typically worn by outgoing people.However,some of the more specific results are strange enough.For example,“practical and functional’’ shoes were generally worn by more “pleasant" people,while ankle boots were more linked with ‘‘aggressive’’ personalities.The strangest of all may be that those who wore‘ ‘uncomfortable looking” shoes tend to have “calm” personalities.And if you have several pairs of new shoes or take extreme care of them,you may suffer from “attachment anxiety",spending lots of time worrying about what other people think of your appearance.There was even a political calculation in the mix with more liberal(主张变革的)types wearing “shabbier and less expensive” shoes.
The researchers noted that some people will choose shoe styles to mask their actual personalities,but researchers noted that volunteers were also likely to be unaware that their footwear choices were showing the deep side of their personalities.
