Natural resources are things that come from the earth. We need to use them often in our daily life. Our natural resources are limited(有限的). This means that they will not1forever. Some are renewable, like when you plant a new tree after you2one down. Others are not renewable, like when you dig coal(煤) out of the3, once it is used, it is gone.
People realise the4that the earth's natural resources are limited, and they can do things to help conserve(节约) those resources.5you try to conserve a natural resource, you try to use less of it, so it will not get used up so6. One way that people conserve fuel, like gasoline, is riding a bicycle or walking when the7is short instead of driving everywhere.
Water is a very important natural resource because we all need it to stay8. We can conserve water.9making sure that our pipes and taps do not leak(漏). We can also make10choices to conserve water, like only using the dishwashers or washing machines when they are full. Everyone can make contributions to saving natural resources.
How old are you? Have you created anything useful? Do you know Kelvin Doe? Let me tell you something about him.
Kelvin Doe is an African boy. Though he is very clever, his family is so poor that he can't go to school. When most teenagers are learning how to solve maths problems, Kelvin Doe is teaching himself to make batteries and generators (发电机) for his neighbourhood. Kelvin is only 22 years old, but has already created batteries and generators by himself. He used things he picked up around the house or from rubbish boxes to create them.
"In my home town, we don't have much electricity and batteries are expensive," Kelvin said. So he decided to make batteries to light up people's homes. Kelvin also owns a radio station. He broadcasts news and plays music for the local people. The station gets its electricity from a generator also made by himself, He wants to help more families in his home town live a happy and comfortable life.
Peru(秘鲁)is the fifth largest Latin American country with a people of 14, 430, 000. Almost half of these people live in the city areas(地区). Around Lima, there were 20% of the total (总数) population in 1961. The population here grew faster than anywhere else and in another 35 years reached 1/3 of the total population.
About 45% of the people are Indians and 50% are white or mixed（混合人种）and the others are Asians, Negroes(黑人)or people from other countries.
In island areas, only about half of the people can read and write, but at the places near the sea, 2/3 of the people can read and write.

Each year there is an increasing number of cars on the roads and streets as millions of new cars and trucks are produced. One out of every six Americans works at putting together the parts of the cars, driving trucks, building roads, or filling car with gas. Americans won't live without cars!
Most Americans would find it hard to think what life could look like without a car. However, some have realized the serious problem of the air pollution caused by the car. The polluted air becomes poisonous and dangerous to health.
One way to get rid of the polluted car is to design a car that does not pollute. That's what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.
Another way is to take the place of car engine （发动机）by something else. Inventors are now working on steam cars as well as electric cars. Many makers believe that it will take years to develop a practical model that pleases man.
To prevent the world from being polluted by car, we'll have to make some changes. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and to go to work by bicycle. Bicycling is thought to help keep the air clean.
But this change doesn't come easily—a large number of workers may find themselves without jobs if a car factory closes down. Thus the problem of air pollution would become less important than that of unemployment.
Although cars have led us to a better life, they have also brought us new problems.

Danny is short and thin. Of all the boys around he is the (瘦的) one. So he is called Bones(骨头) by his friends. He talks more and laughs louder than (任何人). However, he is always unhappy because he is not good at sports.
One day, Danny watched the (男子) marathon(马拉松赛跑) on TV. The runners didn't need to run fast and they just ran on and on. They didn't have big muscles. They were more (像) Danny. He decided to have a try. "Boy, it's better to do a little bit each day," (建议) his mum. The next day, Danny started his practice. From then on he kept on (训练) in the park every morning.
The race day came. There were 109 runners and they were all bigger than Danny.
They all started fast. Danny tried to keep up with (他们). But he fell farther and farther behind. Halfway someone got tired. Danny passed a big guy with big muscles. (突然地) he felt like a switch had been turned on. He passed another one, then a third one ... All the runners were breathing hard and looked tired (除.....之外) Danny. He looked like he could run forever. At that time he didn't see
the crowds or hear them (欢呼). He just ran and ran. At last he raised his arms, like a champion as he crossed the ending line.
In 2011, when British photographer David J. Slater was visiting a park in Indonesia, his camera was taken away by a group of black monkeys. The result was hundreds of monkey selfies(自拍照). The best ones show a monkey smiling toothily for the camera.
Nobody knew they would create a copyright (版权) battle three years later.
Last month, a website put the monkey selfies online under a collection d free photos without Slater's permission (允许).
However, the website refused to do so. They said that according to US copyright law, whoever pushes the button on the camera owns the copyright to the photo.
They said, "US copyright law says that works that come from a non-human source can't ask for copyright. That means monkeys don't own copyright. "
He said he bought the cameras; he spent a lot of money traveling to Indonesia, and it was his carelessness that allowed the monkeys to take his cameras away. All these have made him own the pictures, no matter who pushed the button. In a sense, the monkeys helped him take the photos, Slater said.
Who do you think will win this interesting battle?
A. It was the monkeys but not Slater that pushed the button.
B. As of now, there has been no result in the Monkey Selfie case.
C. Slater then sold the photos and they became popular on the Internet.
D. Slater asked the website to take them down since he owns the copyright.
E. Slater argues that the pictures belong to him as they were taken from his camera.
