The sight of a mosquito can mean trouble to people in many parts of the world. The bite of the mosquito can be deadly. The insects carry serious diseases like malaria (疟疾). It is estimated that almost 630,000 people died from malaria and malariarelated causes in 2012, and most of these cases were in African countries.
In the United States, a group of California scientists are working to develop a more effective and less costly substance (物质) to protect people from mosquitoes. The researchers are investigating the sense of smell in mosquitoes. They found the insects use the same receptor for identifying carbon dioxide in human breath as they do for the smell of our skin. Anandasankar Ray, who is leading the investigation, says scientists tested more than a million chemical compounds (化合物) until they found a substance called Ethyl Pyruvate. He says Ethyl Pyruvate makes the mosquitoes' receptors inactive. “When we apply Ethyl Pyruvate to a human arm and offer it to hungry mosquitoes in a cage, very few of the mosquitoes are attracted to the human arm because only a few of them are able to smell it out,” said Ray.
Genevieve Tauxe, a member of the research team, says it was not easy to find the neurons (神经元) of noble cells that recognize both the smell of human breath and skin. “With the device used to examine the mosquito, we are able to insert a very small electrode (电极) into the part of the mosquito's nose, where its smelling neurons are and where the smell is happening,” said Tauxe.
Anandasankar Ray says a product based on Ethyl Pyruvate may cost less to produce than DEFT, the most effective chemical treatment now in use. He says DEFT is too costly for most people who live in areas affected by malaria.
“Perhaps by finding smells that can attack other target receptors, we will be able to improve upon DEFT and finally have the next generation of insect behaviour control products,” said Ray.ytytzygx.

Wild weather, unexpected coral reefs and dangerous sea creatures… these are the nightmares (噩梦) you can imagine a teenager on a solo voyage (独自旅行) around the world might suffer from. But for Laura Dekker, sailing around the globe seems less a price to be paid than a prize to be treasured.
As the 19-year-old Dutch sailor said in Maidentrip, a documentary released last year about her experience of becoming the youngest person to sail around the world alone in 2012, “I was born on a boat. I lived my first five years at sea. And ever since, all I have wanted is to return to that life.”
With her yacht Guppy, Dekker began her journey at 14 and sailed 50,004 kilometers in 519 days.
The flying fish keeping her company, the dolphins following in her wake and the warm days spent on deck playing the flute as she watched another unforgettable sunset were enough to make others jealous.
But these didn’t always go well. There were terrible moments in which Dekker feared death. On one occasion, a whale almost turned Guppy over. Another time, she battled extreme winds and Guppy surfed down 8-meter-high waves.
Out on the open sea alone, she also got used to living without a fridge, a flushing toilet, and a hot shower.
“As a human being you don’t need much,” she told Stuff.co.nz. “ They might make life more comfortable, but you really don’t need them to be happy.”
In fact, her outlook on life was shaped by the trip. “I wanted the storms. I wanted the calms. I wanted to feel loneliness,” she told The New York Times. “And now I know all these things. It’s the end of the dream I had as a child, and it’s the beginning of my life as a sailor.”According to the text, in which year did Dekker begin her journey of 50,004 kilometers at sea?
| A．In 2012 | B．In 2010 |
| C．In 2009 | D．In 2011 |
The method the author uses to develop Paragraph 5 is ________.

How did Laura Dekker think of her life on the sea?
| A．It was so dangerous and almost ruined her. |
| B．It made her experience happiness and better understand life. |
| C．It is the sailing on the sea that made her well known. |
| D．It brought her great happiness and much comfort. |

Psychology has a new application in the field of medicine. Many doctors, together with their patients, are looking for alternative methods of treatment of physical problems. In large hospitals, modern therapy seems to focus on the physical disease. Patients may feel they are treated like broken machines. Some doctors have recognized this as a problem. They are now using psychological therapy, in which the patient is working with the doctors against the disease with the help of medicine. The patient does not wait for the medicine and treatment to cure him or her, but instead the patient joins in the fight.
The doctor knows that a disease affects a patient's body physically. The body of the patient changes because of the disease. He is not only physically affected, but also has an emotional response to the disease. Because his mind is affected, his attitude and behavior change. The medical treatment might cure the patient's physical problems, but the patient's mind must fight the emotional ones. For example, the studies of one doctor, Carl Simonton, M. D., have shown that a typical cancer patient has predictable attitudes. She typically feels depressed, upset, and angry. Her constant depression makes her acts unfriendly toward her family, friends, doctors, and nurses. Such attitudes and behaviors prevent recovery. Therefore, a doctor's treatment must help the patient change that. Simonton's method emphasizes treatment of the “whole” patient.
The attitude of a cancer patient receiving radiation therapy, an X-ray treatment, can become more positive. The physician who is following Simonton's psychological treatment plan suggests that the patient imagine that he or she can see the tumor in the body. In the mental picture, the patient "sees" a powerful beam of radiation like a million bullets of energy. The patient imagines the beam hitting the tumor cells and causing them to shrink. For another cancer patient, Dr. Simonton asks him to imagine the medicine going from the stomach into the bloodstream and to the cancer cells. The patient imagines that the medicine is like an army fighting the diseased cells and sees the cancer cells gradually dying and his blood carry away the dead cells. Both the medical therapy and the patient's positive attitude fight the disease.
Doctors are not certain why this mental therapy works. However, this use of psychology does help some patients because their attitudes about themselves change. They become more confident because they use the power within their own minds to help stop the disease.
Another application of using the mind to help cure disease is the use of suggestion therapy. At first, the doctor helps the patient to concentrate deeply. The patient thinks only about one thing. He becomes so unaware of other things around him that he is asleep, or rather in a trance（催眠状态）. Then the physician makes “a suggestion” to the patient about the medical problem. The patient's mind responds to the suggestion even after the patient is no longer in the trance. In this way, the patient uses his mind to help his body respond to treatment.
Doctors have learned that this use of psychology is helpful for both adults and children. For example, physicians have used suggestion to help adults deal with the strong pain of some disease. Furthermore, sometimes the adult patient worries about her illness so much that the anxiety keeps her from getting well. The right suggestions may help the patient to stop being anxious. Such treatment may help the patient with a chronic（慢性的）diseases. Asthma （哮喘） is an example of a chronic disorder. Asthma is a disease that causes the patient to have difficulty in breathing. The patient starts to cough and sometimes has to fight to get the air that he or she needs. Psychology can help relieve the symptoms of this disorder. After suggestion therapy, the asthma patient breathes more easily.
Physicians have learned that the psychological method is very useful in treating children. Children respond quickly to the treatment because they are fascinated by it. For example, Dr. Basil R. Collison has worked with 121 asthmatic children in Sydney, Australia, and had good results. Twenty-five of the children had Excellent results. They were able to breathe more easily, and they did not need medication. Another forty-three were also helped. The symptoms of the asthma occurred less frequently, and when they did, they were not as strong. Most of the children also felt better about themselves. Doctors have also used suggestion to change habits like nail-biting, thumb-sucking, and sleep-related problems.

It is one of the most annoying words in the English language and it seems there is no escaping it．The word “huh?” is in worldwide use, a study found.
Researchers discovered that languages spoken in countries from Ghana and Laos to Iceland and Italy all include “huh?”, or something that sounds very like it. They said that while the study may sound silly，the word is an absolutely necessary part of speech. Without it and similar words, it would be impossible to show that we haven’t heard or understood what had been said and this would lead to constant misunderstandings.
But while other words used in the same context, such as “sorry” or “what”, vary widely across languages, “huh?” remains unchanged.
The Dutch researchers carefully studied ten languages from around the world, including Siwu, which is spoken in Ghana, and an Australian Aboriginal language, as well as Italian, Spanish, Dutch and Mandarin Chinese.
They analysed tapes of recorded conversations for words that sounded like‘‘huh?”and were used to request that whatever had Just been said be repeated. All contained a version of “huh?” The word was also found in another 21 languages. While there were subtle differences in each country, all sounded basically the same.
This is surprising because normally unrelated languages will use very different words to describe the same thing. For instance, the Japanese for “dog” is “inu”, while the French is “chien”. It is thought that languages around the world have developed their own version of “huh?” because the sound is quick and simple to form, as well as being easily understood.
The researchers，said that it might seem unimportant to carry out scientific research into a word like“huh?” but in fact this little word is an essential tool in human communication．They also have an answer for those who claim that “huh?” isn’t a word. They say that it qualifies because of the small differences in its pronunciation in different languages. It also can be considered a word because it’s something we learn to say, rather than a grunt or cry that we are born knowing how to make. According to researchers，the word “huh?” is very important in speech because _________．
| A．its stable meaning in language development |
| B．its important function in communication |
| C．its simple and easy sound and spelling |
| D．its popularity in every language |
What is the natural response if you hear the lady you’re speaking to say “huh?”?
| A．You should ask her to repeat what she says before that. |
| B．You should apologize to her for speaking in a low voice. |
| C．You should invite her to share her different views politely. |
| D．You should try to repeat what you’ve just said in a clearer way. |
According to researchers, “huh?”should be considered a word．rather than a sound because_________ .
| A．it is listed in most dictionaries |
| B．it is something humans learn to say |
| C．there is a clear and consistent spelling of the word |
| D．it is pronounces quite differently around the world |
What is the purpose of the text?
| A．To inform readers about research on the worldwide used word “huh?”. |
| B．To argue that “huh?” is the most important word in every language． |
| C．To entertain readers by relating similar idioms in different languages． |
| D．To instruct readers of the differences of “huh?” in different languages． |
Some people would go through anything just to achieve their dream. Kasia Siwosz is proof. For the final year student on the university women’s tennis team, the road to Berkeley, University of California was met with poor advice and misinformation from her home country and two unsuccessful stops along the way that fell short of expectations.
Born in Poland, Siwosz began playing tennis at seven years old and developed the skills that helped her earn a top-50 ranking among the ITF Junior division (国际网球联会青少年赛).. Siwosz wanted to do more with her life than just play tennis, which led her to seek chances that would also allow her to obtain a top education. While most who grow up in the U.S. are naturally accustomed to the American tradition of collegiate sports, such a custom is not as familiar in a country like Poland. “There’s no collegiate sports in Poland and no culture of sports and academic study there. You can only do one, not both,” Siwosz said.
Her desire to have a quality education led her to America to follow her dream. While Siwosz was talented enough to begin her collegiate tennis career, she could only attend community college because she missed the deadline to apply to four-year schools, mainly due to misinformation provided in her home country of Poland.
When she had earned all her credits and was able to transfer, Siwosz made the decision to attend Baylor in Texas. Her friends from Poland put in a good word for the university, saying that it was a good fit because there were many international players at Baylor. “I thought it would be a good idea, but it really wasn’t what I thought it would be,” Siwosz said. “I wasn’t happy at Baylor. The level of tennis was high, but the academic standards were no match and I just wanted more.”
After one year at Baylor, Siwosz’s luck finally began to change when she made the decision to transfer to Berkeley, which was due in large part to Lee, a former Berkeley student. Lee, who is a keen tennis player himself, met Siwosz four years ago in Texas. “I knew she was unhappy there,” he said. “I saw the opportunity for her to come here.” Siwosz visited Lee in Berkeley. “I ended up loving this place and this school,” Siwosz said. “I came here a lot over the summer, I gave it a shot and I ended up with a Berkeley education and a spot on one of the best college tennis teams in the country.”What does “two unsuccessful stops” (Paragraph 1) refer to?
| A．Poland and the U.S. |
| B．Baylor and Berkeley. |
| C．The ITF Junior division and the Berkeley tennis team. |
| D．The community college and Baylor. |
Why did Siwosz want to leave her homeland for America?
| A．Poland had no culture of sports. |
| B．Berkeley had always been her dream university. |
| C．She wanted to play tennis and have a good education. |
| D．She wanted to improve her tennis skills and get a higher ranking. |
What is the main idea of the passage?
| A．How Siwosz realized her dream. |
| B．How Siwosz left Poland. |
| C．How Siwosz became a top tennis player. |
| D．How Siwosz transferred from Baylor to Berkeley. |
