North American back bears are shy animals. They are fearful by nature, and will usually run away if they see or hear people. Because of this, it can be difficult for scientists to learn about these animals.

In order to study black bears, researchers from New Jersey, USA, catch bears and use drugs 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. From these studies, researchers want to find out how many bears live in New Jersey, how long they live, and how many babies they produce.

But in Minnesota, USA, researchers study bears that are completely awake. The bears know the researchers' voices and they are not afraid of die research team. With the help of a few grapes to keep the bears busy, researchers can touch them to check their hearts, look at their teeth, 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 the research methods and the kinds of information that researchers, are able to collect arc quite different.

Answer the questions (根据短文内容回答下列问题)

Each and every year, during Chongyang Festival, citizens of China celebrate the elders in their families and communities. It’s a special tradition which is rooted in the deep value that Chinese culture places on honouring their elders.

Sadly, many of our aging population are seniors without sons, daughters or grandchildren to visit. While they may have great friends, they no doubt miss the tender and loving relationships unique to families. To fill this void(空虚), many volunteers turned up on October 28 at nursing homes around the country in order to spend time with the residents. In some cases, they performed humble(谦逊的) gestures of kindness, such as combing their hair or washing their feet.

While the kind acts were appreciated, one embarrassing story out of Anhui province raised a valuable question. Reportedly, one old gentleman had his feet washed seven times during the day by different volunteers. Is this genuinely(真诚地) caring for the elderly? Many of the residents at the home said that those gestures do not make them feel cared for at all. Their family members or community volunteers may drop by for a few hours of token time, but soon they disappear back into their busy lives.

There is nothing we can give that is more valuable or appreciated than our time. While you may feel like there is barely enough time to care for your many responsibilities, might it be possible to spare just a moment as you walk home from school to sit with a senior who lives in your community? Just five minutes is not going to prevent you from getting your homework done, but it may totally change a day of loneliness into a day of joy for one old man or woman. Do you live far from your grandparents? Why not pick up the phone and let them know you’re thinking of them? Or maybe you could remind them of the “good old days” and mail them a short letter. Imagine their surprise and joy!

We live in a complicated(复杂的) and busy world, but kindness and caring is still a very simple thing.
