The sound of a mosquito can mean trouble in many parts of the world. The bite of the mosquito can be deadly. The insects carry serious diseases like malaria (瘧疾). 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 (物質(zhì)) 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 (神經(jīng)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 (電極) 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.

With the development of science and technology, new inventions, especially new electronic products, have made people’s lives easy and convenient. But as the saying puts: A coin has two sides.
One day, I was walking in the park with a friend and his cell phone rang, interrupting our conversation. There we were, walking and talking on a beautiful sunny day and…I became invisible, absent from the conversation.
The telephone used to connect you to the absent. Now it makes people sitting next to you feel absent. Why is it that the more connected we get, the more disconnected I feel? Every advance in communications technology is a tragedy to the closeness of human interaction. With email and instant messaging over the Internet, we can now communicate without seeing or talking to one another. With voice mail, you can conduct entire conversations without ever reaching anyone. If my mom has a question, I just leave the answer on her machine.
As almost every contact we can imagine between human beings gets automated, the alienation(疏遠(yuǎn)) index goes up. You can't even call a person to get the phone number of another person any more. Directory assistance is almost always fully automated.
Pumping petrol at the station? Why say good morning to the attendant when you can swipe(刷)your credit card at the pump and save yourself the bother of human contact?
Making a deposit at the bank? Why talk to a teller who might live in the neighborhood when you can just insert your card into ATM?
Pretty soon you won’t have the burden of making eye contact at the grocery shop. Some supermarket chains are using a self-scanner so you can check yourself out, avoiding those check-out people who look at you and ask how you are doing.
I am not against modern technology. I own a cell phone, an ATM card, a voice mail system, and an email account. Giving them up isn't wise…they're a great help to us. It's some of their possible consequences that make me feel uneasy.
More and more, I find myself hiding behind e-mail to do a job meant for conversation. Or being relieved that voice mail picked up a call because I didn't really have time to talk. The communications industry devoted to helping me keep in touch is making me lonelier.
So I've put myself on technology restriction: no instant messaging, with people who live near me,no cell phoning in the presence of friends, no letting the voice mail pick up when I'm at home.
1.Which of the following would be the best title of the passage?
A. The Advance of Communications Technology
B. The Consequences of Modern Technology
C. The Process of Communications Revolution
D. The Automation of Modern Communications
2. Paragraphs 5 to 7 are listed as examples, which show that the use of modern communications is ___________.
A. encouraging B. disappointing
C. satisfying D. embarrassing
3.The passage implies that _______________.
A. modern technology is bridging the people
B. modern technology is separating the people
C. modern technology is developing too rapidly
D. modern technology is interrupting our lives
4. What does the writer think to do with the modern technology?
A. We may use them no matter what others are doing.
B. We can throw them away and return to the ancient.
C. We can be far away from them forever.
D. We can use them less and communicate with the people around us.

One hundred and thirteen million Americans have at least one bank-issued credit card. They give their owners automatic credit in stores, restaurants, and hotels, at home, across the country, and they make many banking services available as well. More and more of these credit cards can be read automatically, making it possible to withdraw or deposit money in scattered locations, whether or not the local branch bank is open. For many of us the “cashless society” is not on the horizon---it’s already here.
While computer offer these conveniences to consumers, they have many advantages for sellers too. Electronic cash registers can do much more than simply ring up sales. They can keep a wide range of records, including who sold what, when and to whom. This information allows businessmen to keep track of their list of goods by showing which items are being sold and how far they are moving. Decisions to reorder or return goods to suppliers can then be made. At the same time these computers record which hours are busiest and which employees are the most efficient, allowing personnel and staffing assignments to be made accordingly. And they also identify preferred customer for promotional campaigns. Computers are relied on by manufacturers for similar reasons. Computer analyzed marketing reports can help to decide which products to emphasize now, which to develop for the future and which to drop. Computers keep track of goods in stock, of raw materials on hand, and even of the production process itself.
Numerous other commercial enterprises, from theaters to magazine publishers, from gas and electric utilities to milk processors, bring better and more efficient services to consumers through the use of computers.
1. From the last sentence of the first paragraph we learn that ___________.
A. in the future all the Americans will use credit cads
B. credit cards are mainly used in the United States today
C. nowadays many Americans do not pay in cash
D. it is now more convenient to use credit cards than before
2. If computers record which hours are busiest and which employees are the most efficient, what will businessmen do?
A. They will fire some employees and raise the work efficiency.
B. They will arrange for different employees to do different jobs according to their abilities and performance.
C. They will assign more work for the employees to do.
D. They will allow the personnel to do whatever work they want to do.
3. What does the underlined phrase “ring up sales” in paragraph two mean?

Fear may be felt in the heart as well as in the head,according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.
Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting and pumping blood around their bodies, compared with the point when the heartbeat is relaxed. Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation.
Sarah Garfinkel at the Brighton and Sussex Medical School said:“Our study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart.”
The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces. Dr Garfinkel said, “The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed.Thus, our hearts can also affect what we see and what we don't see—and guide whether we see fear.”
To further understand this relationship,the scientists also used a brain scanner(掃描儀)to show how the brain influences the way the heart changes a person's feeling of fear.
“We have found an important mechanism by which the heart and brain ‘speak’ to each other to change our feelings and reduce fear,”Dr Garfinkel said.
“We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced, we may be able to develop more successful treatments for anxiety disorders,and also for those who may be suffering from serious stress disorder.”
1.What is the finding of the study? ________.
A. Fear is a result of one's relaxed heartbeat.
B. One's heart affects how he feels fear.
C. Fear has something to do with one's health.
D. One's fast heartbeats are likely to cause fear.
2.The study was carried out by analyzing ________.
A. volunteers' heartbeats when they saw terrible pictures
B. the time volunteers saw fearful pictures and their health conditions
C. volunteers' reactions to horrible pictures and data from their brain scans
D. different pictures shown to volunteers and their heart-brain communication
3.Which of the following is closest in meaning to “mechanism” in Paragraph 6?
A. order B. treatment C. machine D. system
4.This study may contribute to ________.
A. treating anxiety and stress better
B. explaining the cycle of fear and anxiety
C. finding the key to the heart-brain communication
D. understanding different fears in our hearts and heads

He is only 12 years old but Utkarsh Tripathi brings out a handwritten newspaper every week on matters like the environment. He does all this to satisfy his wish to “serve the country”. A Class 8 student of the Brij Bihari Sahai Inter College in Allahabad, Utkarsh has been bringing out the newspaper Jagriti for the last one year. And for the four-page, black-and-white newspaper, Utkarsh not only takes the role of a reporter, editor and publisher, but also gives it free of charge.
Jagriti has about 150 readers belonging to various age groups in Allahabad, some 200 km from the state capital Lucknow. “Children make up major Jagriti readers ... my school friends, my seniors in school, teachers and also my neighbours,” he said.
According to Utkarsh’s father Hari Prasad, who runs a coaching institute, his son has a gift for writing and wants to serve the country in some way.
“More than two years ago, he began to read articles in Hindi Daily. One day he said that he wanted to start serving society from his school life itself. I then suggested why not work like a journalist and make people know their rights,” he added. Utkarsh took the suggestion seriously and came up with Jagriti. “I try to cover social issues about environment, women foeticide and others in the editorial section, and also information about public welfare plans and important government policies for the betterment of the poor or children.” Utkarsh said.
Jagriti also has successful stories of scientists, political leaders and other outstanding people.But how does he get time from his studies to bring out a weekly newspaper? “I believe if anyone is passionate about something, he or she can take out some time to realize his dream.” Utkarsh replied.
Utkarsh’s efforts are much appreciated by people in Allahabad. Nutan Devi, a local journalist, said, “For me it’s real journalism …It has renewed the objective (宗旨) of journalism that seems to have now got lost somewhere.”
1. According to the text, Utkarsh Tripathi _____.
A. made the first newspaper about two years ago
