There are many wetlands in China and some of them have become the world's important wetlands. The Chinese Yellow Sea Wetlands are among them. They are in Yancheng, Jiangsu Province. They are home to many different kinds of animals. The world's largest Milu Deer Nature Reserve is in them. More than 700 Milu deer live freely there. There are not many red- crowned cranes in the world, but every winter you can see some in the Red-crowned Crane Nature Reserve in the Yellow Sea Wetlands.

The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine too. They are really good places for wildlife. Offering(提供) food and home to some special kinds of animals is not the only reason why we need to protect wetlands. Wetlands are important because they also prevent flood. But some people want to change the wetlands to make more space for farms and less space for wildlife.

Luckily, more and more people are beginning to realize the importance of wetlands and wildlife. Every year, on February 2nd, many activities are held to tell people more about wetlands.

   The size and shape（外形）of your ears show your character（性格）more than any other part of the face. Other parts of the face change shapes as we get older, but ears do not change their shapes. They only change in size.
   Reading people's character from their ears is a very old science. In the past people thought that a person's ears with colour was dangerous. They also thought that the shape of the ears showed if a person was musical or not. Today, too, many people believe that the size and shape of the ears help you know if a person is musical.
   Ears are all different，and each different thing has a meaning. Next time you look at a person, see if his or her ears are large, medium-size, or small. Look at the lobes（耳垂）. Do they stick to the face? Ears that are always red mean that a person may get angry easily. Ears that are always cold and nearly white colour mean that a person has a nervous（神经质）character.

    Three kids have been learning chemistry for only a few months. But they have already begun to challenge (挑战) a world famous scientist!
Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator (酸碱指示剂). They want it to take the place of litmus (石蕊) paper.
    "We've learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other."
    British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world.
But when the kids did some experiments in class last winter, they saw that the litmus paper didn't turn very blue with base matter. It's hard to get a clear result.
    Will there be a better indicator than litmus paper? The three kids decided to try and find out!
How? They went to collect over 40 plants in parks, gardens and markets. Then they ground (研磨) leaves, flowers and stems (茎) to get the pigments (色素) from them.
    The kids mixed pigments with acid and base. They spent months watching carefully to see which paper showed the best colour change. They decided it was the litmus paper!
    "It's our first scientific journey, Huang said, "But it makes me want to try harder."

What will the weather be like? Some people say they can know what the weather will be like from birds. When they see birds fly high out to the sea , they know it is a nice day, because birds don't like to fly out when it will rain. When the weather will be bad, the birds come back to the beach. A big wind may come with a rain. Birds do not like to fly in a big wind. They may sit in a tree when rain is coming. Other animals can also tell the weather. It's a cloudy day. The rain is coming. Chickens aren't quiet, and they are running here and there. Frogs(青蛙) are making big noise in the pool. If it is a nice day, the frogs will come out of the water.

The government in China ended his one-child policy and let families have two children instead in 2015.

A Chinese Communist Party statement gave a number of reasons for the change in policy. The statement said the change is meant to balance population development, stop a falling birth rate(出生率)and strengthen the country's labor force(劳动力). China, with the largest population in the world, started the one-child policy in 1980. But the government allowed only a small number of couples to have two children. For example, some families in the countryside could have two children, if the first-born is a girl.

In 2013, the Chinese government gave other couples a chance to have two children if one of them was an only child.

Jiang Quanbao, a teacher and population expert, explained how Chinese families react(反应) to the newest policy. "Too many young people in the cities are no longer interested in having a second child," he said. "People in the countryside are more interested. But some of them are already allowed to have two children." At the end of 2014, China had a population of 1.37 billion people. A total of 800 million of them have jobs. But the labor market need of labor by the year 2050. With the two-child policy, an increase in births can solve this problem.

Boys and girls, what do you think of the two-child policy? Do you want to have a new-born brother or sister?

Why Are They Left-handed（左撇的）?

What do Napoleon, Clinton and Wang Nan have in common(共同的)? They are all left-handed. Today about 15% of the number of people is left-handed. But why are people left-handed? The answer is the way the brain(大脑) works. The brain has two halves—the right half and the left half. The right half controls(控制) the left side of the body and the left controls the right half of the body.

So right-handed people have a strong left brain, and left-handed have a strong right brain. The two halves of the brain are about the same size. But each side controls different things. The left side controls language, maths and logic(逻辑). When you remember new words or when you put things in order, you use your left side. The right side of the brain controls your love of art, colour and music. It is also good at recognizing(认出) faces. This does not mean(意思是) that all artists are left-handed and all accountants(会计师) are right-handed. Some right-handed have a strong right brain, and some left-handed have a strong left brain.

We choose food to eat every day．We might know some of the reasons for the choices，but food scientist Dr．

Brian Wansink has found that we are unaware of 90% of our food decision．Here are some"big ideas"in his research on the hidden power that drives our eating．

Food for thought

In one of the studies，Dr．Wansink made volunteers eat chocolate yogurt in a dark room．He told them the yogurt was with a taste of strawberry even though they were all eating chocolate．Finally，65% of volunteers described the yogurt as having a"nice strawberry flavor!"

The research shows that our imagination has an effect on our taste．If you expect a food to taste good，it will．So take a moment before you eat your unpleasant healthy food to remind yourself that you are eating delicious fish and chips．

Our eyes eat first

How your food looks is just as important as how it tastes．Dr．Wansink gave cakes to three groups of people．The cakes were exactly the same but served in different ways．

①Group one got the cake on a nice plate．

②Group two got the cake on a paper plate．

③Group three got the cake on a piece of paper．

Dr．Wansink then asked the people how much they would pay for each cake．

①Group one who got the cake on a nice plate would pay $1.27．

②Group two who got the cake on a paper plate would pay 76 cents．

③Group three who got the cake on a piece of paper would pay 53 cents．

Take some time to make your healthy food look amazing．Cut your fruit into a flower shape and put your colourful vegetables on nice plates．This works really well for your appetite （胃口）．

Out of sight，out of stomach

Dr．Wansink also found that when people sat at the desk full of snacks，they ate 71% more of snacks a day than those sitting near a clear table．We eat what we see．As a result，put all the unhealthy food in your fridge．

Hide it and make it really hard to get to．The closer bad food is，the more you eat it．
