Unit 1 The Changing World 第三课时 能力提升睡综合拓展 一、阅读理解 Besides golden yellow,can gold show other colors?Can water reach 0 C without turning into ice??Yes and yes.Welcome to the world of nanogeochemistry(纳米地球化学).Professor Wan works at an institute in Guizhou.He is a leading scientist in this research field. “Nanogeochemistry is a field that bridges nanotechnology(s纳米科技)and geochemistry (地球化学)，”said Wan.Nanotechnology looks at things as tiny as one-billionth(十亿分之一) of a meter,while geochemistry studies Earth from a chemical point of view.You might think it seems strange to mix these two fields.But Chinese scientists have thought about it since the 1990s,Wan noted.One reason is that high-technology products,especially computers and smartphone chips(芯片)，keep getting smaller but more powerful.. "Nanogeochemistry tries to understand how tiny things form (and spread on Earth. Among them,particles (are one to 100 nanometers in size,Wan said.That is much smaller than a human hair,which is usually 80,000 to 100,000 nanometers wide. In the nanoworld,things act in strange ways because of quantum effects(量子s效应).For example,if gold is made just a few nanometers big,it can shine blue,purple or even red. Another example is water.When water is placed inside nano-sized holes,it can stay liquid 态的)even under-40℃. Nanogeochemistry is important for space research.Wan's team is studying the effects of high-speed impacts (on space bodies.This might help explain how certain metal nanoparticles formed on the Moon,Mars,and so on.

"We didn't know how to begin,said Li Hua."So we spent days 1 online and talking to our science teacher."After many discussions,they chose plastic bottles,old CDs,and cardboard for the car's body. "Our goal was to prove that trash can become something 2,explained Wang Mei. "And we learned how solar energy can power real machines." The hardest part was getting the solar panel(太阳能电池板)to work.“We failed twice,” Zhang Tao said."But on the third try,it finally 3 ! Their teacher,Mr.Chen,praised them,"This isn't just an engineering project.It's about solving real problems through cooperation and4." When the car was shown at the School Science Fair,visitors were 5 amazed."It's not perfect,Li Hua said,"but if more people act like us,our city will become 6." The team also realized that independence doesn't mean working alone."We combined 合）our strengths,”Wang Mei said.“That's the true7 of teamwork.”Now,they plan to enter a city competition."We hope our work will 8 others to protect the environment, Zhang Tao said."Everyone can play a role-no matter how young." Their story shows that with effort,teenagers can truly make a 9.As Li Hua put it, "Don't 10 change.Start it yourself."

As an exchange student(交换生）studying in China,I've known more interesting differences from my country,the UK.For example,people often give fruits and milk to their friends and relatives in China.In my country,they are usually for patients in hospitals. More western people open their gifts at once,although not in places like Germany.It's also important to take off the price tag (before giving the gift. What will you do if you don't like your gift?In Spain,in order not to hurt the person's feelings,you still need to say you love the gift.But if there is the receipt (inside the gift, that means you can change it for something else.
