D

    When a computer works on a group of programs, it can get very hot. Cooling the computer can cost a lot. So some scientists wonder what would happen if the heat from the computer could be used.

    Large Internet companies (公司)such as Google and Microsoft have thousands of computers. As these computers deal with information, they produce lots of heat, so they need huge cooling systems(系统). These systems send the heat into the air.

    A company in Holland(荷兰) thinks paying to make the computers work and then paying again to cool them are a waste of energy. So the company developed a special device—the e-Radiator.

    Boaz Leupe, head of the company, says the e-Radiator works as a heating system and saves money. He explains that the energy is used twice—once to heat the home and once to cool the computer and that the users don't have to pay to cool their computers.

    Five homeowners in Holland are testing the heating system in their homes.

    "We pay for the computer using, so, in that way, homeowners get heating for free," Boaz says.

    Jan Visser is one of the homeowners. "If you use the computer more, the e-Radiator produces more heat," he says. "It can't provide enough heat if you don't use your computer often." But he is ready to try it. It's a great help for his family.

    The company says e-Radiators produce heat temperatures of up to 55℃. It says the system could save its users about $440 a year.

(1)、58.Before the e-Radiator appears, usually the heat of a computer____________.
A、is sent into the air B、helps the five homeowners C、is used twice D、makes the computer work better
(2)、The e-Radiator is mainly used___________.
A、to drive the computer B、to help Microsoft C、to heat the computer D、to provide heat
(3)、The Chinese meaning of the word "device" in this passage is probably "________".
A、节能 B、实验 C、仪器 D、开关
(4)、The best title of the passage may be "________".
A、An Environment Problem B、A New Way to Heat Homes C、The Future Computers D、The Energy to Be Wasted

Each country has its own "art of living". For example, the word "niksen" shows how Dutch people fight stress and tiredness in a fast-paced lifestyle.

The term "niksen" comes from the Dutch word "niks"which refers to"nothing". In practice, "niksen"could be as simple as just relaxing, looking at your surroundings or listening to music- as long as it's without purpose and not done in order to achieve something. Think "simply sitting in a chair or looking out of the window,"says Ruut Veenhoven, a professor at Erasmus University who studies happiness.

"Niksen" sounds contrary to the advice that we were all given as kids. Nowadays, we're always told to stay bus y and work harder than everyone else. But "niksen" is against that attitude. It offers the chance to "deliciously do nothing", as Carolien Hamming told Time. She thinks that "niksen" is very important to staying healthy, since it's a form of men tal relaxation and healing. Just like a wild animal lying in wait for their food,"niksen" seems to be a natural state of being.

For some people,"niksen" can mean more than just men tal relaxation. It's also a way to imagine new ideas or plans. As an early adopter of "niksen", Jenny Holden, adds it to her daily lunch breaks."Within 10minutes of doing nothing-just staring and listening to myself-my head began to clear and pick out my work and home to-do lists", she told the Metro UK. However, for many, doing nothing isn't as simple as it sounds.In fact, it can be somewhat challenging to sit still and stare out a window.

Above all, "niksen" is a suggestion for balancing work and rest. As Dutch-bom writer Ogla Mecking wrote in Whoolly Magazine,"niksen" is the full enjoyment of life's breaks".

Everyone is encouraged to have your "niksen" moments. They give you the strength to face everyday challenges.

The number of people living in the rainforest is rising,but the rainforest itself is becoming smaller!

During the 20th century,huge areas of rainforests were cut down. More and more people in Brazil and Indonesia moved into rainforest areas to find land for living. Local farmers cut down trees to grow crops(庄稼). Large companies have also moved into the rainforests to develop their factories. 

The problem is that the area of the rainforest is becoming smaller and smaller. Scientists say that destroying (破坏) the rainforest is  the earth and should be stopped. But why?Rainforest plants help to clean the air. What's more,different parts of rainforest plants can be used to produce useful medicines and may be the key to solving serious health problems. 

So how can we solve the problem?Governments can make some rules to protect their forests. Companies can create jobs elsewhere,so that fewer people have to live and work in the rainforests. Farmers are encouraged to plant crops in certain areas,and this helps to stop the soil from being washed away and produces better crops. 

More than half of the plants and animals that live in the rainforest can't be found anywhere else in the world. It is important to make sure that these forests are used well and protected by people.

The top﹣selling album(唱片),Songs of the Humpback Whale,was made public in 1970. This collection of nature recordings changed the way many people thought about whales,and it helped save thousands of wha les. 

The album might never have been made without a sound engineer named Frank Watlington. In the 1960s,Watlington was making underwater recordings when he noticed some strange,deep sounds. He realized they were coming from whales. Watlington played the recordings for a pair of scientists named Roger Payne and Katy Payne. When they listened,they fell in love with these beautiful voices at once. 

Katy Payne studied music as well as animals,and she was greatly surprised by how the whales communicated using sounds like an opera singer. She also noticed another interesting fact:the sounds had clear patterns. According to scientists,an animal sound with a repeating pattern is called a song. Some scientists even compared these singing animals to musicians. 

The Paynes thought that other people should also hear the beauty of the whales' songs. So Roger made the recordings into an album. The time when the album came out,whales were often caught,killed and traded for money. Some kinds were even in danger of dying out. Most people had never thought that whales could communicate through songs. But after hearing the album,they began to think differently. 

The album led people to take action to save whales. Musicians began using whale songs in their music,and whales were included in movies and television shows. In 1982,a ban to stop deep﹣sea whaling was made. Before it,in the 1950s and 1960s,more than fifty thousand whales per year were killed. After it,the number went down below two thousand. 

It might seem impossible that just one album could help save the lives of so many whales. But this album told people secrets about whales that had long been hidden under the sea. It allowed whales to finally share their songs with the human world.
