Many animals hide to stay alive. They hide in many ways. Some animals hide in leaves; some animals hide in snow. Usually their colors or shapes help protect them. It’s hard to see an Arctic bear in snow. Its white fur helps protect it. Chameleons(变色龙) can hide by changing colors. Their skin turns the same color as what is around them. Some chameleons can change colors in five minutes.
Many animals try to look bigger than they are to stay alive. Some animals can make other animals think they are very big. If they look very big, animals that are looking for food will run away. Bears can walk on two legs. They look very, very scary. Some animals will run away from them.
Many animals try to stay around other animals. This helps them stay alive. Zebras stay close together so that they can help each other look out of danger. Seeing many stripes at once can also confuse animals that want to eat them. Some birds stay in a circle, each toward a different direction. In this way they can also help each other stay alive by looking around for animals that many want to eat one of them. Animals have ways to stay alive.

How do you go to school every day？By bike or on foot？Maybe you can try a new way﹣taking a S'Cool Bus.
The S'Cool Bus is also called the bike bus.It was invented in the bike kingdom﹣the Netherlands.It is all about green lifestyle，sport and sharing.It's interesting for kids to ride the bus together to go to school.
Also，it is very safe.The bike bus has a driver and eleven seats for kids.Each one has a helmet（头盔） and safety belt（安全带）.There is also a roof on the bus.It can be used on hot days or rainy days to make kids feel comfortable.
Riding the bike bus is one of the greatest ways for children to get to school.Peter，a 10﹣year﹣old pupil，becomes a big fan of the bike bus. "Now the S'Cool Bus is my favorite way of transport.I can ride it together with other kids to keep healthy.It's full of fun."For most parents，it can help them save a lot of time because they only have to pick up their children after school.
The S′Cool Bus is becoming more and more popular in some countries like Germany and France.Its creator Thomas Tolkamp says， "I hope I can sell the bike bus to more countries in the future.As green lifestyle becomes popular，ideas like this get popular，too.I think it will work well in other countries."

Yuan Longping is a Chinese agricultural scientist and educator.He is known for developing the first hybrid rice（杂交水稻）.He was born in Beijing in 1930.He loved playing the erhu，swimming and motorcycling.He graduated from the Southwest Agriculture College in 1953.Then he began teaching at an agriculture school in Anjiang，Hunan Province.
In 1960，a very serious food shortage happened in China.A large number of people died of hunger and illnesses.Yuan Longping could hardly fall asleep at night.He thought it was time for him to do something for his country and people.He decided to find a way to solve the problem.Since then，he had devoted himself to the research of a new kind of rice.
In 1964，Yuan found a natural hybrid rice plant by accident.It had more advantages than others.He worked very hard with other scientists on it for many years.In 1973，the first hybrid rice appeared.It yielded （出产）20% more than that of common rice.Chinese people solved the food problem by their own efforts.
But Yuan Longping didn't stop.He kept on his research.Now the "Super Rice" yields over 1，100 kilograms each mu.Chinese people have enough rice to eat，and hybrid rice has also brought good news to the peoples of many other countries all over the world.
By the achievements，Yuan Longping is called "The Father of Hybrid Rice".

（5）What is Yuan Longping called because of his achievements？
The human brain weighs about 1.4 kilograms，but it can hold much more information than most computers.However，there is another difference between human brains and computers.Computers don't forget information they are given，but humans often do.No one remembers everything，and luckily we don't usually have to.But everyone can improve their memories if they want to.Here are some suggestions.
Try to use new information immediately.For example，if you meet someone who says "Hi!I'm Carlos"，don't just say "hello".Repeat the person's name and say "Hello，Carlos".
Break a big number into small parts.For example，it's hard to remember 109244153.But if you break it into three parts﹣109/244/153，it will become easier.
Write down what you need to remember over and over again.This will help you keep it in mind longer，especially when memorizing formulas or facts.
Always review information.If you bring what you've learned back to your mind，it'll become easier to remember.For example，before you go to sleep，it's a good idea to review the new things you've learned that day.
Discuss things with friends.It is always easier to remember things through discussions.You can have a discussion about what's right or wrong，and it will lead to the right answer.
All of the suggestions are helpful.If you follow them，you are certain to improve your memory.
