    题目列表(包括答案和解析)

    A lift is wonderful. It is really only a small room. Rooms usually stay in one place. Lifts travel up and down all day long.
    Sometimes a worker stands in the lift. He or she operates it up and down. In modern lifts there is no worker. The people walk in. They know what floor they want. They push a button and the lift goes to that floor. It is all very fast and easy.
    Lifts are very important to us. Why? Think about a tall building. Maybe it has twenty floors. Maybe it has fifty or more. Who can walk up all the stairs? Maybe people can climb them one time. Can someone climb thirty floors to an office every day? Can small children walk up to their room on the twenty-fourth floor? Can their mother and father carry food up all those stairs? Of course not.
    We can have high buildings because we have lifts. We could not have all the beautiful tall buildings in the world without lifts. They are really wonderful.

    It’s important to learn about protecting our environment. Here is a 5R rule for us:
    1. Reduce
    If you want to reduce waste, you should use things wisely. Millions of trees are being cut down to make paper. If everyone uses a little paper carelessly and throw it out, soon we would not have any trees left. Other things are also being wasted, and people don’t know what to do with the waste in big cities. So it is necessary to reduce the waste
    2. Reuse
    You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which are too small to the poor. With a family, you may pass on such clothes to younger brothers or sisters.
    3.  Recycle
    Bottles, cans and paper can easily be recycled. By doing so, we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat（压平）and melted (融化) and the melted things are made for new coke cans.
    4.  Recover
    When you buy a box of apples, there may be a few rotten（腐烂的）apples. You have two choices: one is to throw the whole apple away, or you could cut off the rotten parts and eat the good parts. In this way, you are recovering the eatable parts of food.
    5.  Repair
    If one of the legs of your table is broken, you can repair it instead of throwing it away. If you want to change for better ones, It is better for you to sell the old things or give them to other people who can use them after doing some repair. It is true that North America is a “throw-away” society（社会）. But the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.
    【小题1】_______ can be recycled.
    A．Only hard thingsB．Many thingsC．Few soft thingsD．All things
    【小题2】The “recover” rule mainly requires us _______.
    A．to throw waste things away
    B．to cover waste things with earth
    C．to get back the useful parts
    D．to throw the whole things away
    【小题3】We can infer（推断） that the writer of this passage may live in _______.
    A．ChinaB．JapanC．AustraliaD．America
    【小题4】Which of the following is true?
    A．We will have no resources（资源） of nature unless we can do with the waste.
    B．Recycling is the best way to save resources.
    C．If we waste less, we can save more resources of nature.
    D．More things are wasted in developed countries than in developing ones.

    You can’t see any object unless light from that object gets into your eyes．Some of the things you see give off light of their own。The sun，the stars，a lighted lamp are the examples that can be seen by their own light．But most of the things you see are not giving off light of their own．They are just reflecting(反射)light that falls on them from the sun or some other luminous bodies．The moon，for example，doesn’t give off any light of its own．It is not 1uminous．You see it because sunlight falls on it and some of the sunlight reflects on the earth．So moonlight is only second—hand sunlight．
    When you look at a book，it sends some of the light which fails on it to your eyes，and you see the book．If light could be kept out from where you’re so that there would be no light from the book to reflect．Then you couldn’t see the book even with your eyes wide open．Light travels so fast that the time in which it travels from the book you’re reading to your eyes is as short as if there were no time at time．Light reaches us from the moon，which is about 380，000 kilometres away，in only a little more than a second．
    【小题1】You can see the book because________．
    A．your eyes are close to itB．it reflects some of the light
    C．it has light of its ownD．it is big enough to be seen
    【小题2】The Chinese meaning of the world“luminous”is close to_______．
    A．闪光的B．看不见的C．发光的D．明亮的
    【小题3】________has light of its own．
    A．The moonB．The earthC．The sunD．The satellite of Dong Fong Hong
    【小题4】Light travels about_________kilometers per second．
    A．300，000B．100，000C．400，000D．190，000
    【小题5】Which of the following is TRUE?
    A．All the things you can see give off light．
    B．Light from the book is much faster than that from the moon．
    C．The moment you open your eyes，the light from the book travels to your eyes．
    D．Light travels so fast that there is no time for you to read．

    It’s a goal for millions and millions of families every year to keep the Christmas spending within a certain amount of money, but you can still afford the gifts because your loved ones will enjoy them. This concern (忧虑) is becoming greater and greater theses days. Even so, there are several things that you can do to help.

    Hit the sales. No one wants to get up at four o’clock in the morning and fight to get a good deal (交易) on Black Friday ( the first Friday at Christmas time). It’s surely very difficult to pick up the courage and get out there in the cold for a good deal. But sometimes it can be well worth. Many retailers (零售商) offer specials all through the day. Some even offer online Black Friday specials, so we may still be able to get a great deal on Black Friday.
    Read advertisements regularly. Once the Christmas shopping season is coming, retailers will be hungry for business. They will try their best to get us into the store. Please read the weekly advertisements of sales among the major retailers from time to time. We may be lucky enough to find different prices for the same thing in different shops.
    Shop online. Some of us don’t like running from store to store to get the best price on the perfect gift. Some of us don’t like to go out in the cold at all, and then, we can do online shopping.
    The world of online shopping makes it possible for us to visit all the major retailers and some
    specialty stores on the Internet. We can find exactly what we are looking for at the best possible price without even having to leave the house. With traditional Christmas shopping, it will always take us a long time to wait if we want to get the perfect gift.
    【小题1】 The underlined word “specials” in Paragraph 2 means______.
    A．赠品B．奢侈品C．特价商品D．圣诞礼品
    【小题2】We can have more choices to get a good deal ______.
    A．on the Internet B．in specialty stores C．from salesmenD．from retailers
    【小题3】In this passage the writer wants to ______.
    A．tell us to shop online
    B．tell us the best way to do shopping
    C．show us how hard it is to do Christmas shopping
    D．give us advice on how to get a good deal at Christmas time
    【小题4】 From the passage we can infer (推断) that ______.
    A．people are surely able to get a good deal on Friday
    B．it is possible for people to buy the perfect Christmas gifts with less money
    C．retailers will be hungry because they are busy selling Christmas gifts
    D．with traditional Christmas shopping, people can’t buy the perfect gifts
