Japanese researchers are genetically changing mosquitoes so that they become carriers of a vaccine (疫苗) that could vaccinate millions for free. The researchers have already genetically changed a mosquito species so that its saliva (唾液) contains a protein that acts as a vaccine against leishmaniasis (利什曼病), a deadly disease that leads to terrible skin problems. The team confirmed that mice bitten by the genetically-engineered mosquito developed an antibody to the disease, meaning they had built up immunity (免疫力).

"You would be vaccinated without even noticing. You wouldn't need any drug and you wouldn't need to show up at a fixed place for mass vaccinations," said Shigeto Yoshida, the associate professor who has led the research. "Repeated bites would only strengthen the immunity."

Similarly the mosquitoes could be used to help treat malaria (疟疾), perhaps a decade from now, said the malaria expert.

Nearly one million people die each year from malaria — most of them are children — mainly in Africa and Asia, according to the World Health Organization. Now a problem is that no effective vaccine exists. "There is a treatment that works, but it is beyond the reach of people who need to worry about food for tomorrow," Yoshida said.

However, Yoshida expects that the genetically-engineered mosquito will finally help wipe out the deadly disease in the developing world. "Technically speaking, I believe it's a matter of 10 years or so, but it's not clear whether society would accept it," he said.

Another problem is that the genetically-engineered mosquito may still pick up and spread the infected blood of a person who has already caught malaria. Yoshida's team is hoping it can solve this problem by developing a mosquito species that kills the malaria virus inside its own body.

(1)、How have scientists turned mosquitoes into carriers of a vaccine?
A、By changing their genes. B、By killing the virus in their bodies. C、By letting them bite mice. D、By injecting vaccines into their bodies.

(3)、What can we infer from the last two paragraphs?
A、People welcome the idea of using mosquitoes to treat malaria. B、Mosquitoes carrying vaccines may still spread malaria. C、It is not long before people will use mosquitoes to get rid of malaria. D、A mosquito can kill the malaria virus inside its own body.
(4)、The main purpose of the passage is to         .
A、introduce a possible solution to malaria B、encourage people to use mosquitoes to fight against diseases C、show that Japan has very advanced technology D、call on people to help people suffering from malaria in Africa and Asia

    I now work 40 hours a week at a weather company and I love it Compared to when I became a mom, I don't feel bad about being away from my three kids. When I had my first child, I was a busy manager. My husband had a part-time job and cared for her the rest of the time. Once I became pregnant with my second kid, I quit my job to focus fully on writing.

    At first I felt like I was living the dream. I was a work-from-home mom who never had to be away from my children. But working from home can end up being more stressful than working full-time or being a stay-at-home mom.because you're frequently exhausted between work, keeping house and telling sweet faces you don't have time to play. Ever tried writing an article with a baby screaming? It was awful.

    I was so stressed that I eventually started taking my kids to 8 day care center a couple of days a week. The whole reason I worked so hard to be able to write for a living was to be at home with my kids and here I was taking them to a day care center.I thought I was a failure then.

    Over the past five years of being a freelancer(自由作家), I've realized a couple of things. As I wrote six months  ago, "I though I felt bad leaving my daughter for ten hours a day but now she is old enough to ask me to read her a story .Try telling your kid no, 20 times a day. It's cruel. You end up feeling worse for having to ignore them." I also realize not socializing with people weren't good for my mental well-being.

    Not only that, but I can now show my kids that Mom is important and has a job at a flashy office building, something they didn't realize when1 sat around in yoga pants typing on my computer all day long.

    Have you ever noticed what happens to an idea once you express it? Just talking about it or writing it down causes you to make it clear in your own mind. How can you use this to increase your brain power? Start writing.

    By putting thoughts into words, you are telling yourself the logic (逻辑) behind what you think, feel, or only partly understand. Often, explaining a thought is the process of understanding. In other words, you increase your brain power by exercising your “explain power.”

    Try this experiment. Explain how you'll increase your brain power, even if you have no idea right now. Just start with anything, and create an explanation. For example, start with “I'll learn chess,” or “I'll read an article on the mind every week.” Explain how that will help. You'll be surprised how often this becomes a workable plan, and if you actually do this, you'll have a better understanding of your brain from now.

    Another benefit of writing is that it helps you remember. Many, if not most, highly productive people are always taking notes. You can try keeping it all in your head, but if you keep a journal of your ideas the next time you're working on a big project, you'll probably have more success.

    Want to understand a topic? Write a book about it. That's an extreme example, but if you are learning something new, write a letter to a friend about it, and you will understand it better. Want to invent something? Write an explanation of the problem, why you want to solve it, and why it is worth solving, and you're half-way there.

    Writers don't always write because they clearly understand something beforehand. Often, they write about something because they want to understand it. You can do the same. Writing will help bring you to an understanding. Give it a try.

    There is an English saying that “Laughter is the best medicine.” Until recently, few people took the saying seriously. Now, however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter can really improve people's health.

    Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, makes the heart beat quicker and makes people breathe deeper; it also works on several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial(有益的).

Other tests have shown that laughter appears to be able to reduce the effects of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated(忍耐)the pain for the longest time was the group which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminishes both stress and pain.

    As a result of these discoveries, some doctors in the United States now hold laughter clinics(诊所), in which they help to improve their patients' condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

    At 17, Mark Merwitzer might be Florida's youngest lobbyist (游说者). The Miami high school junior appeals to authorities to keep drivers from texting behind the wheel.

    Over the past year, the teen has met with county officials and state legislators (立法者)to argue that the police should be able to pull drivers over just for using their phones. Efforts in past years have struggled to advance, but recently, the bill got full support from the Senate Transportation Committee (参议院交通委员会).

    Like many US people, Merwitzer has seen countless drivers texting behind the wheel. But last spring, while he was riding in the passenger seat of a vehicle, he saw drivers using smartphones in almost every car. A few drivers even appeared to lose control of their cars as they sped along. It dawned on (突然想到) Merwitzer that no one was doing anything to fix the problem.

    We need to teach drivers how to properly and safely use technology behind the wheel which is not using it at all,” said Merwitzer.

    For the 17-year-old teenager, advocating a new state law has been a crazy experience.

    In order to carry out his plan,he put his focus on drumming up (争取)local support by starting an online petition (请愿)and speaking to village councils,

    Merwitzer said the first time he spoke at a council meeting “was a complete stutter fest (口吃表演),” but he quickly adapted to it.

    “It really creates some standards that help everybody realize the importance of keeping their eyes on the road,” said Miami-Dade Commissioner (专员)Levine Cava.

The commissioner has been so impressed with Merwitzer's understanding of the political process. “He really learned very quickly how to be an effective citizen lobbyist,” she said.

    So far, opposition to the bill has come mainly from police departments. Some are worried about the possibility of lawsuits (诉讼)if officers are accused of racially profiling (按种族形象定性) drivers when accusing them of texting and driving,Merwitzer said. The bill also has critics in the House, where lawmakers have yet to make plans for a hearing.

    Merwitzer said he would one day like to be a state legislator, but in the meantime he has a few short-term goals, like finishing school and going to college. Once the legislative session (期间) is over, Merwitzer plans to turn his attention to another local problem: public transportation. “I'd like to focus on that,” Merwitzer said. “It seems like it's a giant mess,”

    A good modern newspaper is an extraordinary piece of reading. It is remarkable first for what it contains: the range of news from local crime to international politics, from sports to business to fashion to science, and the range of comment and special features as well, from editorial page to feature articles and interviews to criticism of books, art, theatre, and music.

    A newspaper is even more remarkable for the way one reads it: never completely, never straight through, but always by jumping from here to there, in and out, glancing at one piece, reading another article all the way through, reading just a few paragraphs of the next. A good modern newspaper offers a variety to attract many different readers, but far more than any one reader is interested in. What brings this variety together in one place is its topicality(时事性), its immediate relation to what is happening in your world and your locality now. But immediacy and the speed of production that goes with it mean also that much of what appears in a newspaper has no more than transient value.

    For all these reasons, no two people really read the same paper: what each person does is to put together, out of the pages of that day's paper, his own selection and sequence, his own newspaper. For all these reasons, reading newspapers efficiently, which means getting what you want from them without missing things you need but without wasting time, demands skill and self-awareness as you modify and apply the techniques of reading.
