牛津版(深圳•广州)2019-2020学年初中英语七年级上册 Unit 5 Visiting the Moon 第2课时 Reading(2)

阅读短文,从每题所给的A、B、C和D四个选项中,选出最佳选项。

    When you look at the sky at night, the Moon looks bigger than the stars. Actually (实际上), the Moon is much smaller than the stars and the Sun. It's much smaller than the Earth. But the Moon is much closer to us than any star. That is why it looks so big. If you hold a coin close to your eyes, it looks big. If you look at it across the Moon, it looks small.

    The Moon moves around the Earth. It makes one trip in about four weeks. The Moon looks flat to us. But it is a round ball, like the Earth.

    People once thought the Moon had fire (火) on it. They thought the fire made it bright. Now we know the Moon is like a mirror. It gets its light from the Sun.

    Our sunlight comes from the Sun, too. What is the Sun? The Sun is a star. The stars we can see have their own light. There are many big stars we cannot see. Their light has burned out. Others are still bright, but they are so far away that we cannot see them. The Sun looks bigger and much brighter than other stars in Galaxy because it is the nearest of all stars. The Sun and the other stars we see are very hot, but the air around us saves us from the heat of the Sun.

    The Sun gives us light and warmth (温暖). It makes plants grow and turns leaves green. It makes life possible on the Earth. It is a life giving star.

(1)、It takes ________ for the Moon to go around the Earth.
A、more than a week B、nearly a month C、half a year D、more than a year
(2)、The Moon is bright because ________.
A、there is some fire on it B、it is near the Sun, too C、there is a big mirror on it D、it can get light from the Sun
(3)、The passage tells us ________.
A、the Sun is not the biggest star B、the Sun is bigger than any other star C、only the Sun can shine D、the Sun is one of the farthest stars from us
(4)、Why do we call the Sun "a life giving star"?
A、Because it gives us warmth. B、Because there are some living things on it. C、Because plants and animals can't live without it. D、Because people have to live in the dark without it.

   Want to save the environment? You probably can't fix everything on your own, but by taking small steps and keeping the environment in mind every day, you can make a difference,
     1. Think Green. Challenge yourself to think about the environment as you live your life. If you shut off lights when you leave the room, turn off your TV when you're not watching it, you'll save energy. If you take shorter showers, you'll save water.
    2. Shop Green. Shopping is fun, but buying things you don't need is wasteful and bad for the earth. Before you buy something, ask yourself how much you'll really use it. Keep yourself away from buying products with unnecessary packaging (包装), and whenever possible, buy things that were locally made instead of those shipped from far away.
    3. Dress Green. Wear green trousers and T-shirts if you want. But what really matters isn't the colour, it's how the clothes were made. If you want to help the environment, the best place to find clothes is at a vintage store, but you might not want to buy everything used. No matter where you shop, keep an eye out for products made from environmentally friendly materials like organic(有机的) cotton, which is grown without the use of pesticides ( 杀虫剂).
    4. Study Green. What's better than learning about the environment? Save it while you learn, It can be as simple as using both sides of a piece of paper before you recycle it, or reusing an old textbook :instead of buying a new one. If you want to do more, join an environmental group at your school, and encourage your friends to join, too.

    Bioplastic(生物塑料) is a kind of plastic, but it is not the same as normal plastic. Normal plastic is made from chemical materials and takes a very long time to degrade(降解). But bioplastic is good for the environment. It is made by using bacteria(细菌) to process(加工) natural sources like vegetable oils, corn or sugar. It can degrade more easily.

    But there is a problem with bioplastic. The "food" that bacteria eat is what we eat. This means that bacteria are competing against humans for the same resources.

    Now scientists have found a new way to make bioplastic——using two kinds of bacteria and sunlight, according to Newsweek.

    One of the bacteria can use sunlight to produce sugar. The other kind lives in the salty waters of Bolivia. It eats the sugar that the first bacteria produce and then it can produce polymers(聚合物). Polymers are used to create bioplastics. The way the bacteria store polymers is similar as humans store fats.

    The new way to produce bioplastic has many advantages. It is 20 times faster than the normal way we produce bioplastic. Moreover, using these two bacteria saves resources.

    Firstly, producing a lot of bioplastic requires corn and sugar, which are used to feed normal bacteria. And growing corn and sugar needs farmland. But these two bacteria can just use sunlight. The land that is saved can be used to grow food for humans. Besides, this system doesn't need rich land or clean water at all, scientists said to Newsweek.

    The next problem scientists face is that they want to put their lab research into real-world practice. By doing this, bioplastic made with these two bacteria can be widely produced in the future.

    Uber (优步)announced that it plans to invest 20 million in developing an aircraft in France over the next five years.

    It will open a new research and development center in Paris﹣its first technology hub outside of North America.

    "France is a perfect home for our next step forward with its strong history of research and development, world class engineers and a unique role in aviation (航空)worldwide,"Uber said in a statement.

    Uber already has R & D offices in Pittsburgh, Toronto, and San Francisco. They focus mainly on Uber's self﹣driving technology, but have also been working on Uber's Elevate flying car program.

    The Advanced Technologies Center in Paris will open later this year and only focus on flying cars. It will conduct research into airspace management, real﹣time communication networks, energy storage, and charging systems.

    Uber's announcement, made at a tech meeting in Paris, has been supported by French President Emanuel Macron, whose ambitious economic reforms are to attract more foreign investment.

    The company also announced a five-year research partnership with Ecole Polytechnique, a leading French institute of technology.

    Uber has been working on its flying car program since 2016. NASA became a partner for the program a year later by developing air traffic management for a fleet of flying cars.

    Uber expects flight to become a daily part of our transportation lives. The company believes it can offer rides in flying cars for about the same price as an Uber X ride. This technology may completely change our transportation lives in the future.
