It is amazing how many of the things in science fiction and movies have become reality.For instance,in the movie Star Trek,the workers could go to a replicator(复制器) and order food,drinks or anything they could program into the computer.Before long,the item would appear.This is possible today,in a way,with technology we have had for years.

Several manufacturers(制造商) have created 3D printers.One company,MakerBot,has created a printer that the average person can afford.It is called The Replicator.You can download a lot of design software from the Internet for use with The Replicator.In the near future,rather than going to a store to buy what you need,you may be able to download what you want from the Internet and print it out at home.

The process was first used with music.At the very beginning,music was recorded onto plastic disks with etching(蚀刻法).Music can now be copied without a physical product.____ Rather than having to buy a physical book or magazine,you can now download them from the Internet in digital form.

This technology is already used in engineering and architecture.Melissa Shoes,a Brazilian foot wear company,is using this technology to create shoes.Rather than having to go through the current process of product design and development,the company is able to design and print shoes for display to see how well they will sell before having lots of them made.

(1)、What is the purpose of referring to Star Trek in the first paragraph?
A、To recommend the movie. B、To introduce the topic of 3D printers. C、To compare science fiction with reality. D、To show the author's love for 3D printers.
(2)、What do we know about The Replicator created by MakerBot?
A、It is not too expensive. B、We can download software from it. C、It can print whatever we want. D、It'll replace shopping in the future.
(3)、Which of the following can best fill in the blank in the third paragraph?
A、The process helps sell more books. B、But books are still printed in physical form. C、The same is also true of books and magazines. D、3D printers can also be used in the music industry.
(4)、What is the last paragraph mainly about?
A、The uses of 3D printers. B、The future of 3D printers. C、3D technology companies. D、The principle of 3D printers.

    If you're looking for a challenging situation to practice your English, pick up the phone. Not being able to see the other person and the body language can make the chatting difficult. {#blank#}1{#/blank#} Here are some tips to guide you through an average phone conversation in English.

1).Greetings

    Every phone call should begin with a polite greeting such as “Hi, how've you been?” or “Nice to hear from you”. Even if you're calling a business contact for a specific purpose, it'd be rude to jump right into business.  {#blank#}2{#/blank#}

2).Getting to the point

    There always comes the point where you want to move on from friendly chatting and get down to business. What should you do in this situation? {#blank#}3{#/blank#} However, if you are waiting to find out why someone called you, you can guide the conversation by saying “So what can I do for you?”

3).Interrupting without offence

    Sometimes you may happen to be speaking with a very talkative person. {#blank#}4{#/blank#} Keep in mind when you'd like to interrupt, and be sure to do it politely. For example, begin with “I'd like to say something here”.

4).Closing the call

    This can be the trickiest part of the conversation! It may be the time to offer good wishes if it's appropriate. {#blank#}5{#/blank#} Sometimes it's easiest to just say you enjoyed speaking to the other person. Also remember cleverly saying the word well at the beginning of a sentence can indicate you're ready to end the conversation.

A.Use the phrase “I'm just calling to...” to change to the topic at hand.

B.Additionally, you may want to confirm any plans you've made.

C.You should make a little small talk at the beginning.

D.You'd better greet him or her in a friendly way.

E.So it may be difficult to get a word in.

F.Practice English through phone calls.

G.Never fear, though!

    Are you a problem shopper? The answer is “Yes”, if you or someone else thinks that you sometimes get carried away with shopping. In other words, do you or does someone else think you are occupied in extreme shopping? If people have regrets later about their shopping, or have an “out-of-control” feeling about the quantities of what they buy or the amount of credit they use, they may be considered to be problem shoppers.

    Extreme shopping can lead to a more serious problem — addictive shopping. Addictive shoppers feel driven by the desire to shop and spend money. They experience great tension which drives them to shop and spend money and they feel a “rush” during the time they are occupied with the shopping activity.

    Extreme or addictive shopping may result from long-time unpleasant feelings, of which anxiety, pain and shame are common ones. When we feel bad inside, we often do something to make ourselves feel better. In this case, we often go shopping.

    A few people shop to relieve their boredom or emptiness. For some people, the motivation is a desire for status, power, beauty or success. Some love to shop as it makes them feel valued in the eyes of the shop assistants. Others shop simply because it makes them forget, at least temporarily, tension, fear or unhappiness in their life.

    Besides, shopping malls are designed to encourage continual shopping. For instance, there are some malls where you can't see clocks displaying the time because they don't want you to become too aware of the time you spend there. What's more, food courts, coffee shops and restrooms are provided, so you don't have to leave the mall because of your physical needs.

    Therefore, once you become aware of how market forces work, you will certainly come to control your shopping behavior. For example, how much time you will spend and what areas you will visit can be decided before you enter the mall. Keep a written account of what items you will buy and how much money you will spend. Make a plan for what you are going to buy before you feel the urge to shop and then stick to it. That is vital for gaining self-control.

    Times are a little tough at our house right now. Neither of us makes a lot of money, but years of experience have taught us how to walk between the raindrops and make it from one month to the next with a fair amount of grace. I cook a lot at home, more when we're facing difficult times. When I know that I have to keep us fed on not much money, I fall back on my grandmother's recipes. She taught me to cook.

    When I was a kid, my twin brother and I spent long summer weeks and Christmas vacations with my mother's parents in the mountains of North Carolina. Rather than go hunting with my grandfather on mornings, I found myself more and more in the kitchen with my grandmother, watching her making a lemon cheese pie with her soft hands.

    My great-grandmother died when my grandmother was 11 years old. As the eldest daughter, she was expected to take on all of the housework while attending school. Throughout the Great Depression, she learned how to make a little food go a long way. Vegetables were cheap, so she cooked a lot of them, mostly only using small amounts of meat for seasoning. Roast beef was a twice-a-month luxury, but there was nothing she couldn't do with a chicken, every part of it. Nothing went to waste.

    Now I understand that her food was sacred (神圣的). I feel connected to my grandmother and to hundreds of years of family when I'm in my kitchen making country food. In the delicious smells is a long tale of victory over hard times, of conquering starvation of not just surviving, but finding joy and pleasure in every meal of every day.

From grandmother I learned to take real satisfaction in feeding people. My grandmother would beam with pleasure over a heavily laden table and say: "Do you know what this would cost at the restaurant?" I never knew what restaurant in particular she had in mind, but I knew that the question was totally not fair, because no restaurant anywhere can cook like a grandmother. But now, thanks to her guidance and years of practice, I can.
