Every child should have a solid science education whether they want to be the next Albert Einstein or Michael Jordan.Science is all around us，it is everywhere，reaching everything that we do.The  “we”  in that last statement includes children.Children that understand how science plays a role in our everyday lives have a wonderful foundation (基础) for success in life.

Children can learn science at any age really.The earlier they start the better.The best way for kids to learn is through play and repetition.There are wonderful science toys for preschool science activities.With play being the best way kids learn，it only makes sense then to introduce toys to them that encourage understanding science.Children love to use their imagination to have fun and to help them understand the world around them.So play is a wonderful time to be introducing science to them.Think of the games that we used to play：Don’t Spill the Beans，Don’t Break the Ice，the Telephone Game，Lincoln Logs，each of these games has science behind it.

Children are by nature curious (好奇的) as they feel out the world，trying to make sense of what is around them.Science feeds that curiosity that they have.It is a hunger that needs to be encouraged and satisfied.Finding these toys is not as hard as one would think.To make sure that you get good quality toys，visit science toy shops online.These are the best places to find unique (独特的) science toys such as 3­D space projectors，or Hydro Greenhouses.

Help your children appreciate the world around them by understanding the world around them.This way，they understand how we are all connected together.Children will not only question the world，but be able to come up with answers to those questions on their own.Science is life.

　　The villagers of Yaluma in Southern Mexico are some of the poorest people in the country. But now they have an extra source of income.They are being paid to grow and develop forests by the organization in charge of Formula One racing (一级方程式赛车),which pumps 5,500 tons of carbon dioxide (CO2) into the air every year.The idea is that the forests being planted around Yaluma will absorb this amount. It will also provide people there with money while wiping out motor racing's environmental debt.
　　Projects like this go under the name of "carbon trading". The basic idea is that governments and companies can buy the right to pump CO2 into the air by investing in green projrvyd. They can buy so-called "carbon credits" from countries which have succeeded in reducing CO2 emissions(排放物).
　　Supporters of carbon trading say that it brings money and green technology to poorer countries.It also provides a new way of doing busingess and spreading prosperity. They point out that the process of globalization will give people everywhere the most possible choice of products and services. Carbon trading is just another way of bringing that about. It is a "win - win" situation.
　　Opponents argue that nature comes before lifestyle. CO2 emissions need to be reduced, not bought and sold. And they believe that the rich world should lead the way.People might be willing to change the way they live to help save the world, but not to help the rich countries keep a lifestyle that depends on pollution.
　　Supporters of carbon trading believe in unlimited growth.Opponents believe that nature sets limits to the choices we make on how to live.It is "don't do " against "can do". It is life against lifestyle.
　　It is believed that modern lives are about choice.For example,the world can choose to take the danger of global warming seriously.And the sooner we choose to do it, the more choices we have about what to do next and the more time we have to do it in. We can also choose to pay no attention to the danger of global warming to keep our lifestyles. Then one day nature may give us no choice at all,and maybe not much of a life,either.
　　64.Carbon trading is discussed in the text in order to show the importance of ______ .
　　　A.reducing pollution B.taking care of forests
　　　C.spreading prosperity D.choosing lifestyle or nature
　　65."Carbon credits" may be used to ______.
　　　A.get the right to pump CO2 into the air
　　　B.get the right to pump CO2 into poor countries
　　　C.learn about the way to reduce CO2 emissions
　　　D.improve the way to reduce CO2 emissions
　　66.We can infer from the text that in the "win - win" situation _____.
　　　A.rich countries perform their duty to help poor countries
　　　B.poor countries get what they need from rich countries
　　　C.both rich countries and poor countries get what they need
　　　D.rich countries learn from poor countries in reducing pollution
　　67.In the opinion of people who are against carbon trading,the rich countries should ____.
　　　A.guide poor countries in reducing CO2 emissions
　　　B.show by example how to reduce emissions
　　　C.offer more help to save the world
　　　D.improve their lifestyles to keep the world clean
