Every single one of us can help to deal with climate change and prepare for the effects.

We all have an effect

on the environment through our use of resources (资源) and burning fossil fuels for everyday activities such as driving cars and heating our homes. If we all do our best to protect our environment, then we can make a real difference.

Consider the environmental effects of:

1       the energy used in your home

2       the way you travel

3       the food you eat

Do everything you can to reduce your carbon footprint (足迹) and not only will you be making fewer effects on the environment, but you511 probably find that you'll also save money and lead a healthier life.

Increasing water efficiency in your home reduces the amount of energy used for water treatment and can save money and fight against climate change at the same time.

Other things you can do

Here's a list of some simple things you can do that will help reduce your carbon footprint:

1       insulate (使隔热) your home

2       turn down your central heating by one degree (度数)

3       use energy efficient lighting

4       try not to fly

5       share a car with others

6       ride your bike for short journeys

7       eat local, seasonal, fresh, unprocessed (未加工的) food

8       reduce the amount of waste you produce and reuse or recycle as much as you can

    With the development of science and technology, our daily life is becoming more colorful and more convenient .

    What do Napoleon, Clinton and Wang Nan have in common? They are all left-handed.

Today about 15% of the people are 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 half controls the right side of the body. So right-handed people have a strong left brain, and the left –handed people 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, Math 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 color and music. It is also good at recognizing (认出)faces. This does not mean that all artists are left-handed and all accountants (会计师) are right-handed. Some right-handers have a strong right brain, and some left-handers have a strong left brain.

    Can plants eat people? Maybe not, but there are many plants that eat meat. Some of them are big and they can eat small animals. One famous meat-eating plant is the Venus flytrap(捕蝇草).

    The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of a book. They can open and close very quickly. The fly (苍蝇) cannot get out. In about half an hour, the leaf presses (压) the fly until it is dead. Then, the plant covers(覆盖) the fly. Slowly, the plant eats the fly.

    Why do plants do it? Most plants get what they need from the sun, the air, and the ground (地面). In some places, the ground is very poor. It doesn't have all these important things, especially nitrogen(氮.). Animal meat has a lot of nitrogen, so many plants eat meat to get what they need.

    Let's hope that some of the bigger plants don't get the same idea!

    What will life in the future be like? Will it be much better than it is now? And what will we be able to do in 10, 20 or 30 years' time?

    Genetic engineering (基因工程)may help us make the perfect human. Babies may grow up to play basketball like Yao Ming or look like Cecilia Cheung. Also, we may be able to bring the dead back to life. Maybe people will be able to meet and talk with their dead family members.

    Over the next 20 to 50 years, it will become harder to tell the difference between humans and machines. Perhaps we will be able to make copies of ourselves, so we will appear to be alive long after we are dead. People may be able to find ways of putting the life of a person into a new body.

    Nanobots(纳米机器人)will be important. We will use them when we are sick. For example, when we have a stomachache, we will swallow (吞下) a nanobot and it will travel through our stomach, taking a video of what's happening there. The video will help the doctor cure us.

    In the future, computers may have their feelings. They may be able to think better than us. We may be more and more interested in computers and the internet, spending all our time in front of computers. Perhaps we will forget our real needs. Perhaps we will become super couch potatoes weighing 250 kg!

    If you're ever apart from your children, a new study says just talking on the phone will help just as much as a hug(拥抱).

    If you're a parent who spends long hours on the job, you probably feel sorry for spending so much time away from your kids. But the results of a new study show that a mother's voice alone can be just as comforting to an anxious child as physical contact(接触).

    In an experiment, researchers from the University of Wisconsin Madison asked a group of girls between the ages of 7 and 12 to solve math problems in front of judges—a stressful situation for anyone. Before the girls were set to give their answers, the researchers measured their levels of two hormones(荷尔蒙): cortisol, which goes up during stressful periods, and oxytocin, the "love" hormone, which goes down at the same time.

    After the girls finished the problems, some of them got to meet up with their mothers right away. The moms came in and hugged the girls. Another group of the girls didn't see their mothers, but received phone calls from them, in which their mothers told them how well they'd done. The final group had no contact with their mothers, but instead watched an animal movie, March of the Penguins.

    Finally, the girls' hormone levels were measured again. Although the movie was interesting, it did nothing to reduce the children's anxiety—but, surprisingly, both the physical contact and phone calls from their mothers had the same effect on reducing the girls' stress levels.

    So, no matter how old you are, if you're feeling stressed about something in your life, a phone call to Mom might be just the key to help you feel better.
