North American back bears are shy animals. They are fearful by nature, and will usuallyrun away if they see or hear people. Because of this, it can be difficult for scientists to learnabout these animals.
In order to study black bears, researchers from New Jersey, USA, catch bears and usedrugs to help them go to sleep. Researchers then work out the size and the weight of the bear,take blood to test for diseases(疾病), remove a tooth and take it to the lab to find out its age. Fromthese studies, researchers want to find out how many bears live in New Jersey, how long theylive, and how many babies they produce.
But in Minnesota, USA, researchers study bears that are completely awake. The bears knowthe researchers' voices and they are not afraid of die research team. With the help of a few grapesto keep the bears busy, researchers can touch them to check their hearts, look at theirteeth, and do other jobs.Researchers can also walk or sit with bears for hours and make videos to learn about their everyday lives.
In both places, the main purpose is the same—to make sure there is a healthy population of black bears. But theresearch methods and the kinds of information that researchers, are able to collect arc quite different.

Sitting on exercise balls brings more than a smile to students and teachers.
Some fourth-graders at Conrad Weiser West Elementary School in Womelsdorf love their new chairs-—probably because they're not really chairs at all.
The kids are sitting on the air-filled balls. But different from those just for exercise, these have small legs that keep them from rolling. Sitting on a chair all day in school can make anyone want to move around. So, more and more teachers are letting students have a ball. By using exercise balls instead of common chairs, teachers find students' posture(姿势) and attention improved.
Dotti Pownall, a fifth-grader teacher in West Virginia, has been using balls as chairs since December 2008. "The students love them." she says. Pownall took a survey of her students. She found that 80 percent, thought sitting on the balls helped them concentrate(专注) better:
"Besides, they’re fun,b" says Pownall.
According to WittFitt,b a company that has sold balls to more than 200 schools, they can improve kids' posture and classroom behavior.
Exercise ball chairs are getting popular in classrooms, from preschool to college. Some adults (成人) even use them at work.
Lisa Witt felt so stro
ngly about the use of balls as chairs that she started WittFitt. She said the company not only encourages the use of balls but also educates teachers and students on how to use them. "We sell balls in 24 s
tates in America, three provinces in Canada and Japan." says Witt.Sitting on exercise balls can______.

When I was a girl of 10, I joined the school cross-country team and practiced twice a week, on the 1,8-km course I'd never really run before and I thought the course would be easy. It was a real shock I ran out of breathe(喘气)within the first few minutes. I never realized how tiring running could be but I didn’t t think about give up.
Over time,I did get a little bit faster. However, I was really slow. In races, I would finish close to last. I'd always have to stop more than once, especially in the longer races, which were 2. 5 to 2. 8 km. After every race, I'd go home and cry. But 1 still didn't stop running, holding onto that picture of crossing the finishingline and finally doing well.
Then one of my friends joined the team, too. She could run easily and even came in the 18th in a big race! I felt so slow and my confidence(自信) was lower than ever. I became so nervous when I thought of the races that I wanted to give up badly.
Still. I refund to. Finally. 1 realized that the reason I was to nervous was that I was always worried that I wasn't ready for them. So a few weeks before the next 2. 8-km race. I practiced running almost 3 km every day. which helped me improve my pace(步伐).
When the time came for the big race, all that practicing really paid off. I stopped only once and my pace was so much better.
I realized that I’d finally gotten happiness with running. But the funny thing was. It didn't come from doing better, Instead, it came from the fact that I hid tried harder and never given up. Before she took the 1.8-km course, the writer________.
