Why does the chicken cross the road? To get to the other side.
Most people know this joke. But recently, some people have been much more worried about how the grizzly bears(灰熊)and mountain lions can cross the road.
“Millions of animals die each year on US roads,” the Federal Highway Administration reports. In fact, only about 80 ocelots(豹猫)exist in the US today. The main reason? Road kill.
“Eco-passages(生态通道)” may help animals cross the road without being hit by cars. They are paths(道路)both over and under roads. “These Eco-passages can be extremely useful, so that wildlife can avoid road accidents,” said Jodi Hilty of the Wildlife Protection Society.
But do animals actually use the Eco-passages? The answer is yes. Paul Beyer of Northern Arizona University found foot marks left by mountain lions on an Eco-passage that went under a highway. This showed that the lions used the passage.
Builders of Eco-passages try to make them look like a natural part of an area by planting trees on and around them. Animals seem to be catching on. Animals like grizzly bears are using the bridges and underpasses.
The next time you visit a park or drive through an area with a lot of wildlife, look around. You might see an animal overpass!

Kate’s Blog Shut up zoos, Not animals! Many people believe that it is fun to visit zoos, but maybe they are wrong because zoos are just jails(监狱) for animals. The difference is that criminals get out after a certain period of time while animals cannot. Animals in cages are boring to look at. Everyone knows what a tiger looks like, and we’ve seen them on TV. So why make animals suffer (使痛苦) by shutting them up for people's fun? Shut the zoos instead! Posted by: Kate on May 13, at 17: 14 |
Comments 3 Comments * I partly agree. But some zoos aren't for our fun. I have just come back from a zoo in Chengdu, it saves pandas and breeds them because pandas are rare (稀有的) animal. So, I don’t think all the zoos are the same. Posted by: Edward on May 14, at 8: 09 *Totally agree! Each time I go to visit the zoo, I never look at the poor animals’ eyes because they look so sad and lonely, living in the small and dirty cages. I hope they will all come back to nature in the near future, so they can live happily and freely with their families. Posted by: Jack on May 14, at 11: 43 *In my opinion, I think zoos are amazing places for kids. They can play with animals and have fun there. At the same time, they can learn a lot about animals. Why shut up? Posted by: Daisy on May 15, at 9: 24 |

【推荐1】Jack,
Thanks for your letter. How is it going with you? It’s Friday today, but we don’t go to school. It’s sunny, so my friends and I are having a great time on the beach(海滩). It’s a really nice place.
The water is blue and clear. Many birds are flying over the sea. Many people are swimming in the sea. Some boys are playing games. Many people are sitting on the beach. A girl is drawing pictures on a chair. Another girl is taking photos. We are happy.
What are you doing now?
Write to me.

【推荐2】If you feel stressed at school, what can you do to make yourself happier? Some may eat their favorite food or listen to some music. Others may go for a walk or get some exercise. A new study found another great way to lower students’ stress—playing with dogs.
Scientists studied 105 students between the ages of eight and nine. 35 trained dogs and their trainers also took part in the test. The children were divided into 3 groups. The students in the first group spent 20 minutes with a dog and its trainer. They watched the trained dogs perform and even played with them. They did this twice a week for 4 weeks. The second group spent the same amount of time (时长) doing exercise to relax. The last group did neither of these things.
During this time, the scientists recorded the students’ cortisol levels (皮质醇水平). Cortisol is a stress hormone (激素). The more stressed you feel, the more cortisol you will have in your body. What did the scientists find? Both the second and third groups showed rises in cortisol levels. The first group, however, showed no big increase. And the children in this group had the lowest cortisol levels right after playing with the dogs.
According to the study, students enjoy playing with dogs, and it helps them become happier. The stress hormone falls over time this way, which is good for students’ health. But here comes the next question: Is 20 minutes of playtime with a dog the best amount of time? Scientists are going to keep working to find out the answer.

【推荐3】Seahorses are small, thin fish. Even though they’re fish, seahorses aren’t great swimmers. Instead, they often use their tails (尾巴) to hold onto something in the water.
There are over forty different kinds of seahorses. Many kinds of them are in danger because of the actions of humans. Sometimes people catch and sell them as pets. They are also sometimes caught by accident when boats are trying to catch other fish.
Seahorses are unusual because they are the fathers who carry the babies. Fathers can carryover 100 babies at a time. When babies are born, they are about the size of a grain of rice.
Last year, around 380 seahorses were set free into the wild. To begin the project, scientists collected three “pregnant (怀孕的)” father seahorses and brought them to the aquarium (水族馆). After the babies were born, the scientists kept them at the aquarium for five months, looking after them. About a month before the young seahorses were set free, the scientists created eight underwater “hotels” to provide a safe place for them to develop. Putting the hotels into the sea ealy allowed the hotels to be covered with small sea life that can help provide food for the seahorses.
This is the fifth time the scientists have set free seahorses into the area. Brett Fenton, a scientist of this project, said, “We have high expectations (期待) that we’ll see the number of the animals grow.”

Some animals are born helpless but their mothers protect them. A newborn kangaroo is the size of a bee. She stays in her mother’s safe pouch. She doesn’t open her eyes for at least five months. A newborn monkey cannot walk. His mother carries him.
Other baby animals can walk soon after they’re born. They learn to run with their mother when danger is near. A baby zebra can run an hour after she is born.
Some baby animals are born in a place that is safe. Other baby animals are born in the open. Baby wolves are born in large holes. A baby elephant is born on open, grassy land. Other elephants make a circle (圈) to protect her.
Animals that drink their mothers’ milk are called mammals. A mother bear’s milk is fatty and rich. Baby bears need lots of fat to keep warm in winter. They have milk for six months. Baby zebras drink milk for six months or more! As baby animals grow, they need solid (固体的) food. Baby lions eat what their mother can catch.

Make a list of what to do first. Then make a plan and follow it. Start with the most important thing. E. Talk openly. You can ask your friend to tell you what’s happened. If you say something wrong, say sorry. Tell your friend your feelings. F. Practice more. Many people get nervous when speaking in front of people. The more you practice speaking, the more confident you will be. G. Listen carefully. Learn to take notes fast. That will help you hear and understand what the teacher is teaching in class. |
【推荐3】Do you know there is a connection(关联) between music and language? You may not believe it. But recent studies show that music can improve certain language abilities in the brain. Now, let’s look at two examples.
Recently, researcher Kris has done a research. In his study, he divided the people into two groups. The people in the first group were musicians, while those in the other group had no musical training. He asked these people to listen to a person talking in a noisy room.
As a result, the musicians were able to hear the talking person more clearly. You may wonder why. The answer is that musicians can hear better because they learn to pay a certain sounds. Think about violinists. When they play with the group, they hear their own instrument and others’, too. But they must listen closely to what they are playing, and pay no attention to the other sounds. In this way, musicians are able to concentrate(全神贯注) on certain sounds, even in a room with lots of noise.
A doctor at Harvard Medical School works with stroke (中风)patients. These people cannot say their names, addresses, or other information normally because of their illness. However, they can still sing. He was surprised to find that singing words helped his patients to speak. Why does this work? The doctor isn’t sure. Music seems to make different parts of the brain work.
Music can improve concentration, memory, listening skills and language abilities. It can even help sick people get better. Playing an instrument or singing can help us do better in school and keep our brain alive as we get older. Music is not only enjoyable but also good for us in many other ways.
