Tiredness, coughing, a runny nose and a sore throat—among all sicknesses there is probably none more common than the flu, which we all get now and then.
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.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. |
With the example of the SARS epidemic in Paragraph 5, the author intends to .
| 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 |
What makes the H7N9 bird flu more frightening than the H5N1 bird flu according to the text?
| 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. |
What are people advised to do to protect themselves against the H7N9 bird flu?
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.

While astronauts in space get to do many exciting things, they miss out on ordinary things that we all take for granted—being able to walk on firm ground, hanging out with family and digging into a slice of hot steaming pizza. Though not much can be done about the first two things, there may soon be a solution to the third one, thanks to this cool 3-D pizza printer!
About a year ago, NASA offered $125 ,000 to Anjan Contractor, a 3-D technology expert, to build a device (设备) that would allow astronauts to make pizza on demand. The mechanical engineer promised that his invention would produce pies in large quantities that looked, tasted and even smelled like pizza made in common ovens.
Late last year, the engineer presented a video of his first prototype (原型) that begins by creating a single slice of dough (面团) that is cooked and printed at the same time. Then comes the tomato “sauce” — a mix of tomato powder, oil and water and finally, a protein slice that resembles cheese. While the video doesn’t show the baking process, the inventor says that once the pizza is printed, it can be ready to be consumed in 7 seconds.
While the pie in the video looks delicious enough to attract any pizza lover, Anjan Contractor is far from ready for astronauts. That’s because he still has to find a solution to make the food container in the printer last for 30 years. Though that may sound unrealistic, actually it is not.
Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients (配料) and then they are reduced to the powder form. This, as you can imagine, will not be so easy. But, while the printer may not be ready for space, it certainly looks ready enough for people on earth. Hopefully, NASA and Contractor will consider selling it to those not fortunate enough to go to Mars!Why does the author mention the things that astronauts in space cannot do?
| A．To ask us not to take common things for granted. |
| B．To show they live a difficult life there. |
| C．To show their life is boring in space. |
| D．To introduce the topic of the text. |
NASA offered $ 125, 000 to Anjan Contractor mainly to _______.
| A．create some new type of 3-D printer |

| D．produce pizza in large quantities to earn great profits |
The biggest challenge that Anjan Contractor is faced with now is probably that _______.
| A．he has no money left to go on with his research |
| B．the pizza doesn’t seem appetizing to pizza lovers |

| D．A 3-D pizza printer has been used to make pizza |
Military training has long been considered a ritual(仪式) that freshmen must go through in order to officially start their college lives. While some question the necessity of such training. Many students see military training as a campus tradition that should be maintained.
Early in February, the Ministry of Education issued a new regulation that colleges and universities should carry out a minimum of 14 days compulsory military training for freshmen.
In a report by Beijing Evening News, Hou Zhengfang, a Beijing-based education PhD, questioned the benefits of military training. “The training routine does little to improve students’ physical fitness over only two weeks’ time. Maybe some disaster prevention training, such as earthquake survival or escaping from fires would be of greater benefit.”
Meng Yang, a 19-year-old freshman at Guangxi University, fainted during training. She said that many students, especially girls, are willing to train under direct sunshine. “For me, military training is physically challenging and even damages my health.”
According to Li Jian from the student affairs office of Guangzhou University, feeling dizzy happens frequently during military training and the school has received a lot of complaints from both students and parents: “But I still think military training is a good thing. Students are easier to manage after the military training. They became more positive about their new environment after the training.”
Although autumn is fast approaching Beijing, the noon heat burns 3300 freshmen on Tsinghua University’s campus. Chu Jinjing, a freshman majoring in medicine, did feel some discomfort while training in sweaty clothes in the glaring heat, the 18-year-old still enjoyed being part of group going through strict exercises. “By going through this tough training, students bond faster and a sense of belonging to the school can be formed. I’ve made a lot of friends already.”
According to the Ministry of Education, the purpose of military training is to teach students discipline, the spirit of teamwork and endurance. But in reality, according to Xiong Bingqi, deputy director of the 21st Century Education Research Institute, the effect is not satisfying. “Such goals require long-term development. It is unrealistic to expect military training to make a difference in only 14 days.” He thus suggests that it should be up to schools to conduct military training in a way that best suits their students.
However, Wang Wenhui, an 18-year-old freshman from Xi’an Jiaotong University, sees military training as a tradition that reaches beyond character building. “From junior and senior high school to college, we join military training to start a new journey. I would feel a bit incomplete without it.”

The dodo is among the most famous extinct creatures, and a poster child for human-caused extinction events. Despite its bad name, and the fact that the species was alive during recorded human history, little is actually known about how this animal lived, looked, and behaved. A new study of the only known complete skeleton(骨架) from a single bird takes advantage of modern 3-D laser scanning(扫描) technology to open a new window into the life of this famous extinct bird.
The study was presented at the 74th Annual Meeting of the Society of Vertebrate Paleontology in Estrel, Berlin. Leon Claessens, Associate Professor at the College of the Holy Cross, and lead researcher on the study said that, "the 3-D laser surface scans we made of the fragile dodo skeletons enable us to reconstruct how the dodo walked, moved and lived to a level of detail that has never been possible before. There are so many outstanding questions about the dodo bird that we can answer with this new knowledge."
A complete dodo skeleton, found by an amateur collector and barber, Etienne Thirioux, on the island of Mauritius between 1899 and 1917, has remained unstudied, even though it is the only complete dodo skeleton from a single individual bird known to exist. All other skeletons are incomplete combinations, meaning that they are gathered from more than one individual. In addition, Thirioux constructed a second, partially combined skeleton, which contains many bones that also belong to a single bird. "Being able to examine the skeleton of a single, individual dodo, which is not made up from as many individual birds as there are bones, as is the case in all those other combined skeletons, truly allows us to appreciate the way the dodo looked and see how tall or fat it really was," said Juilan Hume, of the Natural History Museum UK, a co-author on the study.
The scans were performed on site in Durban, South Africa, and allow examination of the biology of this mysterious extinct bird in detail for the first time. Using the newest digital tools and techniques, the scans provide an insight into how the flightless dodo may have developed its giant size, and how it walked and lived in its forest home. According to Kenneth Rijsdijk, a biologist from University of Amsterdam, “the skull of the dodo is so large and its mouth so strong that it is easy to understand that the earliest naturalists thought it was related to sharks and other birds of prey（猛禽）, rather than the pigeon family.”
The underlined phrase “a poster child” in Para. 1 is closest in meaning to “ ”.

If it really is what’s on the inside that counts, then a lot of thin people might be in trouble.
Some doctors now think that the internal(内部的) fat surrounding important organs like the heart or liver could be as dangerous as the external fat which can be noticed more easily.
“Being thin doesn’t surely mean you are not fat,” said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have scanned nearly 800 people with MRI machines to create “fat maps” showing where people store fat.
According to the result, people who keep their weight through diet rather than exercise are likely to have major deposits of internal fat, even if they are slim.
Even people with normal Body Mass Index scores can have surprising levels of fat deposits inside. Of the women, as many as 45 percent of those with normal BMI scores (20 to 25) actually had too high levels of internal fat. Among men, the percentage was nearly 60 percent.
According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the belly first, but at some point, the body may start storing it elsewhere.
Doctors are unsure about the exact dangers of internal fat, but some think it has something to do with heart disease and diabetes(糖尿病). They want to prove that internal fat damages the body’s communication systems.
The good news is that internal fat can be easily burned off through exercise or even by improving your diet. “If you want to be healthy, there is no shortcut. Exercise has to be an important part of your lifestyle.” Bell said.What is the passage mainly about?
| A．Thin people may be fat inside. |

| B．exercise plays an important role in people’s life for keeping healthy |
| C．thin people usually have internal fat even if they are slim |
| D．it is easier to burn off internal fat than external fat |

I am a writer. I spend a great deal of my time thinking about the power of language—the way it can evoke (唤起) an emotion, a visual image, a complex idea, or a simple truth.Language is the tool of my trade. And I use them all—all the Englishes I grew up with.
Born into a Chinese family that had recently arrived in California, I’ve been giving more thought to the kind of English my mother speaks. Like others, I have described it to people as “broken” English. But I feel embarrassed to say that. It has always bothered me that I can think of no way to describe it other than“broken”, as if it were damaged and needed to be fixed, as if it lacked a certain wholeness. I’ve heard other terms used, “limited English,” for example. But they seem just as bad, as if everything is limited, including people’s perceptions(认识)of the limited English speaker.
I know this for a fact, because when I was growing up, my mother’s “limited” English limited my perception of her. I was ashamed of her English. I believed that her English reflected the quality of what she had to say. That is, because she expressed them imperfectly her thoughts were imperfect. And I had plenty of evidence to support me: the fact that people in department stores, at banks, and at restaurants did not take her seriously, did not give her good service, pretended not to understand her, or even acted as if they did not hear her.
I started writing fiction in 1985. And for reasons I won’t get into today, I began to write stories using all the Englishes I grew up with: the English she used with me, which for lack of a better term might be described as “broken” ; and what I imagine to be her translation of her Chinese, her internal (内在的) language, and for that I sought to preserve the essence, but neither an English nor a Chinese structure. I wanted to catch what language ability tests can never show: her intention, her feelings, the rhythms of her speech and the nature of her thoughts.
The author used to think of her mother’s English as .
| A．impolite | B．amusing |
| C．imperfect | D．practical |
Which of the following is TRUE according to Paragraph 3?
| A．Americans do not understand broken English. |
| B．The author’s mother was not respected sometimes. |
| C．The author’s mother had positive influence on her. |
| D．Broken English always reflects imperfect thoughts. |
The author gradually realizes her mother’s English is .
| A．well structured |
| B．in the old style |
| C．easy to translate |
| D．rich in meaning |
What is the passage mainly about?
| A．The change of the author’s attitude to her mother’s English. |
| B．The limitation of the author’s perception of her mother. |
| C．The author’s misunderstanding of “limited” English. |
| D．The author’s experiences of using broken English. |
