When I was little, I’d see tons of bats flying around streetlights at night in my neighborhood in upstate New York. But I’ll never forget the first time when I saw a bat up close. By the time I turned 7, though, I noticed something strange: All the bats in my neighborhood had disappeared, and I wondered why.

Then, three years ago, when I was 11 and visiting the state fair, I learned what had happened to my town’s bats. A disease called “white nose syndrome” had killed 93 percent of New York State’s bats. I was horrified. Then I wrote a letter to the host of an environmental program on the local radio station, asking if they could do a show on bats. They did!

But I still wanted to find a way to educate people face to face. I reached out to a teacher I had in elementary school and asked if I could make a presentation to her class. I described how bats help farmers by eating crop-damaging insects. It went over so well that other teachers started requesting me. Over the past three years, I’ve talked in front of everyone from 5-year-olds to senior citizens! Many people think that bats are blind, and that they always carry diseases, but none of that is true. The more I present, the more I notice that I am changing minds.

And while getting people to respect bats is pretty hard, getting them to respect me has been difficult too. When I first applied to host a booth (摊位) at a local street fair, the managers thought I was too young. But I refused to take “no” for an answer. I continued to make my case, and they finally said yes! The best part is, I impressed them so much— 100 visitors on my first day — that they now invite me back every year.

Teenagers who drink alcohol are at higher risk of becoming victims of violence, a Cardiff University study has found.

A team from the School of Dentistry’s Violence Research Group studied drinking habits in children aged 11 - 16 in England. They found not only a link between drink and violence but also that children who drank were more likely to be hit, even if they weren’t violent themselves.

The researchers are now calling for measures to prevent alcohol misuse to reduce injury risk. Current policy focuses on reducing aggression but this research shows that there should be equal effort to reduce victimization.

More than 4,000 children were surveyed at 13 schools at four local authorities in the North, the Midlands, London, and the South. The study found that 25% of 11-year-olds were drinking monthly and 3.6% daily, with 12.8% admitting to getting drunk 3 to 5 times a year. By the age of 16, 40% were drinking weekly and 6.2% were drinking every day. The research also showed 22.6% of 16-year-olds were getting drunk more than 21 times a year.

The study, which has just been published in the Journal of Adolescence, found a strong link between frequency of drinking and frequency of hitting other people.

However, children who reported drinking monthly were also three times more likely to be hit. Adolescents(青少年) who drank but didn’t get into fights were more likely to be hit than those who did fight.

Professor Jonathan Shepherd, who led the research, said a lot of previous alcohol-related violence work had focused on the offenders(惹事的人) rather than the victims. His team is calling for more prevention work from parents and teachers in the first two years of secondary school by taking advantage of the “teachable moment”, that is, immediately after a student has missed school because of drunkenness.

Previous work by Professor Jonathan Shepherd has shown drinkers may be more at risk of violence because of reduced physical co-ordination, poor decision-making in threatening situations and isolation while out late at night. He said, “This new study seems to be the first to show a direct link between alcohol misuse and victimization. There now needs to be much more effort put into reducing alcohol misuse in order to reduce injury.”

Wisconsin has long been home to incredibly successful research and innovation thanks to our famous academic research institutions and some of the brightest scientific minds. From discovering how Vitamin D can best be absorbed, to unlocking the potential of stem cells, Wisconsin has pioneered remarkable breakthroughs in science that have improved health, saved lives and created jobs. These scientific breakthroughs have not only led to life-saving medical technologies but also have fostered (培育) a strong power in Wisconsin economy.

Across America, groundbreaking research supported by the National Institutes of Health (NIH) alone adds millions of dollars to our economy every year. In fact, NIH funding generated an estimated $58 billion in economic output nationwide in 2014. NIH funding spurs economic growth by supporting jobs in research and by generating biomedical innovations that are turned into new products. NIH-supported innovations also influence improvements in health that can bolster the economy, improve productivity, and reduce illness and disability at home and across the globe. But, budget cuts and inadequate funding for NIH in the past decade have put both medical innovation and our next generation of researchers at risk.

Today, too many of our talented young scientists are deciding to do something else, or are leaving the country to pursue their research. Simply put, scientific and medical innovation depends on our ability to foster, support and invest in these new researchers.

That is why I have worked across party lines with Senator Susan Collins of Maine and introduced the Next Generation (NextGen) Researchers Act. Our act builds opportunities for new researchers, helps address the debt burden that young scientists face today, and invests in the future of research, science, and innovation. This commonsense proposal would create the “Next Generation Researchers Initiative” within the NIH Office of the Director to coordinate (协调) all current and new NIH policies. The legislation (立法) also directs the NIH to consider recommendations from a National Academy of Sciences (NAS) comprehensive study and report on fostering the next generation of researchers.

Finally, we must demonstrate a commitment to our future scientists who, like so many of their peers pursuing other fields, are struggling with crushing student loan debt. Our plan would also increase the amount of loans that can be forgiven through the NIH’s loan repayment programs to better account for the current debt load of new scientists. Higher education should be a path to prosperity, not suffocating debt, and this provision not only helps make higher education more affordable, but can help give new researchers a fair shot at pursuing their dreams.

The Next Gen Researchers Act will help to empower our next generation of researchers from Maine to Wisconsin, and across our country, with the resources they need to continue to lead the world in groundbreaking biomedical research and development. I’m proud to have earned the support of the University of Wisconsin-Madison, the Medical College of Wisconsin, and many others, for my bipartisan work supporting Wisconsin’s leadership in science, research and innovation.

At a time when America’s young researchers are facing the worst funding in decades, our best and brightest minds deserve to know that our country stands with them and is committed to building a stronger future.

Mosquitoes have an extraordinary ability to target humans far away and fly straight to their unprotected skin. Regrettably, mosquitoes can do more than cause an itchy(发痒的)wound. Some mosquitoes spread several serious diseases,including Dengue,yellow fever and malaria.

Over one million people worldwide die from these diseases each year. New research now shows how mosquitoes choose who to bite.

Mosquitoes need blood to survive. They are attracted to human skin and breath. They smell the carbon dioxide gas, which all mammals breathe out. This gas is the main way for mosquitoes to know that a warm-blooded creature is nearby.

But mosquitoes also use their eyes and sense of touch. Michael Dickinson is a professor at the California Institute of Technology. His research shows how these small insects, with even smaller brains,use three senses to find a blood meal.

Michael Dickinson’s team used plumes—a material that rises into the air of carbon dioxide gas into a wind tunnel. They then used cameras to record the mosquitoes. The insects followed the plume.

Then, the scientists placed dark objects on the lighter colored floor and walls of the tunnel. Mr. Dickinson said, at first, the mosquitoes showed no interest in the objects at all. “What was quite striking and quite surprising is that the mosquitoes fly back and forth for hours. These are hungry females and they completely ignore the objects on the floor and wall of the tunnel. But the moment they get a hit of CO2, they change their behavior quite obviously and now would become attracted to these little visual blobs (斑点).”

This suggested to the researchers that a mosquito’s sense of smell is more important in the search for food. Once mosquitoes catch a smell of a human or animal,they also follow visual signals.

1.What do mosquitoes mainly use to find their targets?

A. Sense of smell B. Sense of touch

C. Sense of sight D. Smart brains

2.The first response of the mosquitoes to the objects in the experiment is _______.

A. to fly to the dark ones

B. to catch and stick to them

A. Don’t let them see us.

B. Use dark objects to stop them.

C. Make them fly back and forth for hours.

D. Attract them to objects full of carbon dioxide gas.

4.What can be the best title for the text?

A. How Do Mosquitoes Survive?

B. Why Do Mosquitoes Need Blood?

C. How Do Mosquitoes Choose to Bite You?

D. Why Do Mosquitoes Attack the Human Being?
