1 . Without energy in our bodies, we wouldn’t be able to do anything. We couldn’t walk, talk, or even play. Energy is usable power. And all energy is related(相关的) to some kind of movement(运动).
All living things need energy, no matter what they do. Plants get their energy from sunlight. Animals that eat plants take the energy stored in the plants. Plants and animals use energy every day as they grow. So plants have to take in sunlight, and animals have to eat plants or other animals.
It’s not only living things that have energy. A dead tree has hidden energy. When we burn its wood, it gives off warmth, as “heat energy.” The Sun makes heat energy as it keeps burning. The Sun gives off not just heat but also light, as “light energy.” A battery(电池) in a flashlight makes it shine, producing light energy. But if we put the same battery in a radio, we get music. A battery’s energy is known as “electrical energy.” And in a toy car, that electrical energy produces movement.
If we couldn’t use heat, light or electrical energy, we couldn’t drive cars or cook food. Energy is very important in modern life.
1. How do animals get their energy?By
2. What does the sun give off?
The sun gives off
3. How many kinds of energy are mentioned in the third paragraph?
There are
4. What does the underlined word “it” refer to in the third paragraph?
It refers to
5. What does the passage mainly talk about?
It mainly talks about
2 . What do you do with your rubbish? Throw it out? You don’t know what you’re missing. The Santa Fe Show included more than 800 pieces of folk art from nearly 50 countries.
The artists come from many different countries. Still, they all share one thing. They take objects that are normally thrown away and make them into objects that are beautiful, useful and fun. All the works were made from discarded(丢弃的) wood, cloth, and plastic. The artists may not think of what they do as recycling, but that’s exactly what it is.
Fine artists might work with expensive materials. On the other hand, in poor countries rubbish might be the only material folk artists and toy makers can afford.
The objects in the show also call attention to recycling. Reducing the amount of rubbish is an important idea in the modern world.
In 2005 the United States created 243 million tons of rubbish. That’s about 4.5 pounds per person per day. Back in 1980 only 15 million tons of rubbish were recycled in the United States. Compare that with 79 million tons in 2005, thanks to growing awareness(意识) and local government rules. Many products today include recycled materials. So next time you throw out the rubbish, keep an eye out for treasure.

3 . Hello, everyone! I’d like to tell you something about a famous scientist named Qian Xuesen. He was born in Hangzhou, Zhejiang Province on December 11, 1911. After he graduated from Shanghai Jiao Tong University in 1934, he got a chance to study in the USA. After he graduated, he became a teacher as well as a researcher who studied rockets and missile theories(火箭与导弹理论).
When he was 44, he returned to his motherland and the country’s space research was almost blank. In 1956, he set up the first research institute of rockets and missiles. He made such important contributions(贡献) to the missile and space programs that he was honored as “The Father of China’s Missiles”. The Chinese people are proud of him.
He passed away on October 31, 2009 at the age of 98, but all the Chinese will remember him forever. His devotion(奉献) to his country was expressed in his saying, “My career is in China, my success is in China and my destination is in China!” When someone said he could make much more money if he stayed in the United States, he laughed and said, “My family name is Qian. but I don’t like qian.” His spirit encourages us to love our country and devote ourselves to science.
