Scientists are placing robotic dogs in the homes of lonely old people to test whether they can improve the quality of life for humans. Alan Beck, an expert(专家) in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study on the effect of robotic dogs on old people's depression (沮丧) , physical activity, and life satisfaction.
In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, scientists will collect baseline data(数据) for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the scientists will review the data to test if it has produced any changes in the life of its owner.“I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady. “When I'm watching TV, he'll stay in my arms until he wants down. He has his own mind.”
The AIBOs respond to certain orders. The scientists say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
“At the beginning, it was believed that no one would relate(与……相关) to the robotic dog, because it was metal and not furry.” Beck says. “Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters' blood pressure, oxygen levels or heart rhythms(心律). AIBOs may even one day have games that can help stimulate(刺激) older people's minds.”

（1）、The purpose of Beck and Edwards'study is to _____________.

A、understand human-animal relationship B、make lonely old people's life better C、find the causes of old people's loneliness D、improve the animal-assisted research

（2）、 In the research, the old people are asked to _____________.

A、note the activities of AIBOs B、keep AIBOs at home for 12 weeks C、record their feelings and activity D、study the collected information

（3）、What does the underlined word "removes"mean?

A、moves again B、is movable C、doesn't need D、need

（4）、What is the better point of AIBO than live dogs?

A、It is easier to keep at home. B、It can help the disabled people. C、It responds to all the human orders. D、It can watch TV with its owner.

（5）、The writer seems to suggest that the future robotic dogs may__________.

A、cure certain diseases B、keep old people active C、change people's ideas D、look more like real dogs

    There is not enough oil in the world now. As time goes by, it becomes less and less, so what are we going to do when it runs out? Perhaps we will go back to use horses, carriages and bicycles.
    In the Second World War, some people didn't use gas made from petroleum （石油）in their cars. They made gas from wood and plants instead. The cars didn't go fast, but they ran, so this was better than nothing. However, in the future, we can't cut down all our trees to make gas; we need our trees for other things, too.
    Besides different types of gas, we can also use electricity(电) to run our cars but first we must make the electricity! Some countries have coal and they make electricity with that, but we might not always have coal, either. Other countries have big, strong rivers and they can use the power of water to turn turbines(涡轮机) and make electricity more easily and cheaply.
    We are also able to get power from the ocean tides. We put turbines into the mouth of the river. Then the tide comes in, the water turns the turbines and then it goes out, it turns them again.
    Which of these ways will be used to run our cars in the future?

    We live in the computer age. People use computers to do much of their work. But few people know how to look after them. Remember the following when you use your computer:
    ① Keep your computer in a cool ,dry room. Too much or too little heat is bad for computers. Damp (潮湿) is also bad for them.
    ② Do not let people smoke near your computer. Smoke of all kinds is very bad for many parts of a computer.
    ③ Do not eat or drink when you are near your computer. Pieces of food and a little water in the keyboard are also bad for a computer.

       Do you still get free plastic bags from the supermarkets? Things have changed.
       China has banned（禁止）free plastic bags in shops and supermarkets，and people have to pay for using plastic bags. The rule started on June 1st. It came because our country tried to make less litter. Making super-thin plastic bags has also been banned.
       The Chinese once used about 3,000,000,000 plastic shopping bags a day，and they have caused pollution of the environment. The bags have become a main cause of plastic pollution because they are easy to break and people throw them away here and there. So the Chinese people are encouraged to bring their own bags for shop ping.
       What kind of shopping bag is the best to bring? Some students in Chongqing have a good idea. They make their own shopping bags. They use old clothes to make cloth bags，and send them to their parents as presents. They also ask their parents and friends to use cloth bags instead of plastic ones. They think it is their duty to protect the environment.

A city without cars would be very strange, right? But Venice is such a city.

Venice is in the northeast of Italy. It wasn't built on land, like Beijing or Shanghai, but on more than 110 islands. Seawater is everywhere around the city.

Even so, travel isn't difficult. The waterways have always been the best way to get around. There are 117 waterways and more than 400 bridges that can guide you where you want to go. People in Venice move from place to place by boat.

Water makes the city special, but it is also a big problem. Sometimes tourists will have such strange experiences. One moment they walk across the Rialto Bridge, and there's nothing special. But when they come back to the bridge an hour later, it's underwater and everyone is wearing rain shoes.

Once, people used too much underground water. This made the city get lower little by little. Now the city has gone down by 23 centimeters. Another problem is the rising seawater. The temperature has risen over the years. This has made the ice of the Arctic Ocean (北冰洋) melt( 融化). Every year, high waters hit the city in autumn and winter. When a lot of water comes, more than half of the city is underwater.

Scientists are trying different ways to stop the city from getting even lower. The Italian government has asked some of Italy's biggest companies to build the MOST project, which was planned to be build under the seawater to stop the rising water. Anyway, this project is helping solve the problem.

What will our homes be like in the future? Here are some predictions:

Want to take a shower when you get home? You'll be able to let your smart water heater(热水器) to start heating up when you're on your way home..

Did I turn off the oven? Did I close the window? Everyone may have a moment like that. But in the future, your home will check these for you.

In your home of the future, all of your devices (设备) can work together to make your life more comfortable. When you turn on the lights in the morning, your windows will open at the sometime. The lights will slowly turn off by themselves after the sun appears.

Your home may have dangers. The hackers (黑客)could open your door and cause a mess at your home through your phone or other devices. Your home will tell you about it, but you can't arrive in time. So people will have to be careful of their personal information.
