As a kid, Joanna Buckley wasn’t interested in science — until she had a chance to try it. That happened when she got a chemistry set for Christmas.
“Over the course of a few weeks, I’d completed every experiment. But in the process, I polluted my parent’s dining room carpet and burnt the kitchen worktop with the spirit burner,” she says.
Now science is Buckley’s job. She works in the chemistry department at the University of Sheffield in England. “I realize, first-hand, how important it is to have something or someone to show you why science is so great,” she says. Now the good news is that citizen science appears.
Citizen science takes the fun of experimenting a step further than Buckley’s at-home chemistry kit. That’s because these experiments are real, looking for novel answers.
“Compared with a one-off experiment, what’s cool about citizen science is that students get that this has a purpose,” Prunuske says. “Students want to do a good job, because they know scientists are going to use the new data in their own research.”
Long agrees. “Kids like that it’s real. And they like that it’s important, that it matters.” Citizen-science projects have made big discoveries. One found a previously unknown galaxy cluster （星系团）. Another project helped assess how much damage a big earthquake had caused in Japan. And one of the first citizen-science projects helped scientists learn where butterflies go every winter.
Some adults worry about teens losing interest in science. That’s one reason they hope that fun, exciting citizen-science projects can help them keep in touch, Long says. And she has some evidence that it’s working, “Last year, we did have a couple of students say, ‘I really think I want to be a scientist now. ’”

It’s hard to be a bird in a world which is in the charge of mankind.
You can hardly hear yourself sing, let alone hear the songs of your friends… and worst of all, you can’t hear a predator(捕食者). Noise is almost everywhere, especially noise from traffic.
Researchers have tried to study the influence of road noise on animals by looking at animals living near noisy roads.
“We figured out a way to have just the noise without any of the other effects of the road, and to do that we put many speakers in a forest where there was no road,” said Chris McClure, a biologist at Boise State University and The Peregrine Fund. He and his team carried out their experiment at a place popular with birds in Idaho as they fly south for the winter.
While the noise kept lots of birds away, some remained. But they had trouble putting on enough weight to support them in the next part of their migratory journey.
“They have to take food but they also have to avoid getting eaten by a predator. But these two things can’t be done at the same time because to eat, they have to look down, which means they aren’t looking at predators.”
And when it’s too loud, they can’t hear the alarm calls of other birds. So they have to waste time looking for predators instead of searching for food.
By 2050, it’s thought that enough new roads will be built to circle the planet more than 600 times. But there’s an easy solution to the noise problem—“Lowering speed limits does a lot.”
So next time you’re driving through nature, just slow down a little. It’s safer for you and the wildlife. And you can enjoy the view a little longer.
1.Who does the word “you” in Para 2 refer to?
A.A driver. B.A predator. C.A researcher. D.A bird.
2.Why did the researchers do the experiment in a forest without roads?
A.To prevent birds from being hit by cars.
B.To separate noise from other effects of the road.
C.To test a larger number of birds.
D.To put as many speakers as possible.
3.Why can’t birds put on enough weight with much noise around?
A.They can’t concentrate on looking for food.
B.They have to fly south for the winter.
C.They can’t hear the alarm calls.
D.They feel afraid of the noise.
4.What is advised to do to protect birds from the noise problem?
A.To build enough new roads.
B.To carry out more experiments.
C.To enjoy the view a little longer.
D.To drive slowly through nature.
“Cleverness is a gift while kindness is a choice. Gifts are easy – they’re given after all. Choices can be hard.” ---Jeff Bezos.
I got the idea to start Amazon 16 years ago. I came across the fact that the Internet usage was growing at 2,300 percent per year. I'd never seen or heard of anything that grew that fast, and the idea of building an online bookstore with millions of titles was very exciting to me. I had just turned 30 years old, and I'd been married for a year. I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn't work since most start-ups don't, and I wasn't sure what to expect. MacKenzie told me I should go for it. As a young boy, I’d been a garage inventor. I'd always wanted to be an inventor, and she wanted me to follow my passion.
I was working at a financial firm in New York City with a bunch of very smart people, and I had a brilliant boss that I admired very much. I went to my boss and told him I wanted to start a company selling books on the Internet. He took me on a long walk in Central Park, listened carefully to me, and finally said. “That sounds like a really good idea, but it would be an even better idea for someone who didn't already have a good job.” That logic made some sense to me, and he convinced me to think about it for 48 hours before making a final decision. Seen in that light, it really was a difficult choice, but eventually, I decided I had to give it a shot. I didn't think I'd regret trying and failing. And I suspected I would always be haunted by a decision not to try at all.
After much consideration, I took the less safe path to follow my passion, and I’m proud of that choice. For all of us, in the end, we are our choices.

Pastime is a bi-monthly magazine for curious young minds. Many of the topics we write about won't be covered in the classroom. All the articles are written in a lively style, and each one is paired with drawings by some of the country's most talented artists.
◇ History focuses on archaeological(考古的) sites around the world where archaeologists work to unearth important finds.
◇ World includes stories about daily life, folk tales, and culture and traditions of the people and places.
◇ Sport includes nutrition tips, information about up and coming young athletes, and sports events.
◇ Art stimulates a child's cultural life, from film to theatre through to writing and music.
On top of all that, Pastime is packed with items to stimulate a youngster's imagination, including pages of puzzles and a step-by-step guide to creating their own impressive-looking drawings.
In every issue, we review the latest books top authors write for this age group. There are short works of fiction written especially for Pastime by some of our best writers.
We know that children at this age are dealing with many emotions and sometimes difficult feelings, we have a personal advice page to reply to questions dealing with personal and moral questions.
Unlike many of today's throwaway comics, Pastime is written and designed to be kept and treasured. We know children love going online---but we also know how much they enjoy holding a printed magazine in their hands, and the excitement they get when each new issue drops through the letterbox personally addressed to them.
