A Super Space PlaceThe International Space Station (ISS) is being built by thousands of people from 16 countries. All these people are trying to find out if humans can one day live in space.Floating 230 miles above Earth, the ISS currently looks like a giant building-block project out in space. United States space shuttles and Russian rockets have been transporting tools and pieces of the station into space to help finish building it. From the beginning of its construction in 1998 to its completion, more than 100 major pieces will be assembled to create this amazing space station. When finished, it will be the largest structure ever to float above Earth. The ISS will be larger than a football field and will weigh about one million pounds.In addition to helping build the space station, the crews are trying to answer such questions as these: How does space travel affect germs? Does the body break down food and nutrients differently in space? Some day, the station may even serve as a launchpad (发射台) for missions to other planets, such as Mars.Because of its large size, the ISS needs a lot of power. This power comes from solar energy. To create solar energy, large panels are lined with special materials. These materials collect the sun's energy for power and change the sun's rays into electricity. So what does it cost to build such a structure? It costs over $60 billion dollars. Although this may seem very large, it may be a small price to pay for a project that enables some of the world's finest scientists to work together, exploring space for the world's future.5. Plants on the ISS will grow stronger than those on Earth.

The ISS doesn't need too much power for its large size.

Are Humans the Only Animals with Emotions?Do animals have emotions, and if so, which ones? Scientists and animal lovers often debate this issue. In the past, many scientists believed that animals were not capable of showing complex human emotions such as empathy (共情). Empathy is the understanding of and sharing in another's feelings. For example, if your little brother's rabbit dies, you probably would feel bad for him.Several recent experiments support the theory that animals feel empathy. In 1964, one study showed that rhesus monkeys would not accept food if another monkey got an electric shock. Likewise, biologist Marc Bekoff reports that when he was watching elephants in Kenya, he noticed an elephant that had been crippled for years. Although the elephant moved very slowly, other elephants never left it behind. They'd stop walking, check on her, and then wait for her. Bekoff also tells of Alaskan little bears whose mother was shot and died. One little bear had been wounded, so he walked and swam painfully slowly, but his sister never left his side.There are reports of animals showing emotions besides empathy, too. In 2000, a humpback whale was trapped in fishing lines off California's coast. After divers freed the whale, it played with each diver, seeming to show gratitude. Gorillas, llamas, and many other animals appear to express grief when a mate dies. And then there's the story of the two abandoned dogs that were taken to an animal shelter. When one of them went blind, the other led his companion around the new environment until the blind dog learned its way around. Maybe humans and animals aren't so different after all.11.
