In 2013, Bezos, the CEO and founder of Amazon Inc., made headlines when he announced that within a few years, the company would use unmanned drones(无人机)to deliver packages within 30 minutes after an order was placed. Since Amazon Prime Air was publicized the night before “Cyber Monday,” some just regarded it apublicity stunt(噱头) designed to draw attention to the company. It turns out they were wrong.

On December 7, 2016, Amazon revealed that it had completed its first Prime Air delivery in Cambridge, UK. The package, containing a bag of popcorn and an Amazon Fire TV, were loaded on to the unmanned vehicle from a local fulfillment center and delivered to a two-story farmhouse several miles away – all within 13 minutes after the items were bought!

The company also announced that the service is now available within the five-square-mile range of the Cambridge area, seven days a week during daylight hours. The thinly populated rural area, with few dozen residents distributed amidst vast areas of farmland and fields, is perfect for testing the drones.

Unfortunately, even if the trial is wildly successful, many challenges still remain before drone delivery becomes a reality for most of us. While the drone may do fine in rural areas, they remain untested in crowdedurban cities where they would bump into barriers like buildings or trees. There is also fear that theautonomous flying vehicles could injure people as they come down to drop their packages. The drones and their load are also damaged by destroyers.

  Then there are the delivery logistics(后勤保障). Amazon will not only have to ensure that every Prime Air customer has a special landing flat surface, but also come up with a practical solution for apartment residents who do not have accessto an open space where the drone can land. Hence, while Amazon Prime Air may someday be a reality, for now, we will just have to wait for two “long” days to receive our packages!

28. Why was the trial carried out in Cambridge area?

A. Amazon couldn’t find out drone landing space in crowded urban cities.

B. The vast rural areas with smaller population were perfect test sites.

C. Drone flight was prohibited where there were impassable barriers.

D. The company had many logistics to guarantee service quality there.

29. It can be inferred from the text that _________.

A. the new service will save customers more time and money.

B Amazon is the early pioneer of drone flight in the world

C universal drone package delivery has still a long way to go

D the injuries by drones have got the local residents in panic

30.What is the main idea of the text?

A. Drone delivery reached customers in a shorter time.

B Bezos tried to expand its delivery service in Cambridge.

C. Amazon was the first company to use drone technology.

D Amazon tried to deliver package to customers by drone.

Practical ways to get motivated

Be mindful of your “why”

If I need to clean the floor, but I really don’t like cleaning, then I won’t feel very motivated to do it. However, if I have a big enough reason to do it — because I’m having some guests to come over, or I love the feeling of having a clean floor, then that “bigger purpose” can be strong enough to get me to act, even though I don’t enjoy cleaning. If I stay mindful of why I’m doing it, I can get motivated to do it.   36  

    Celebrate your successes.

    It’s easy to get down on yourself because you haven’t reached your goal yet. You may overlook all of the hard work and small goals that you’ve accomplished. Remember to reward yourself and to celebrate your successes.   37  In the same way, how can you motivate yourself if you’re not going to reward yourself and celebrate your successes?

      38  

Imagine how good you’ll feel when you’ve reached your goal. Take a moment and think about how you’ll feel and what you’ll think after you’ve achieved it. What does it feel like?   39  Focus on that feeling, and use it to drive you right now to move towards your goal. Just think of how good it will be.

    Get inspired.

    Read stories, watch movies, listen to other people who have achieved what you want to achieve. Imagine what they had to go through to get to where they are. Imagine how big the heart is of some of your biggest heroes and how badly they wanted what they achieved.   40  

  A. Imagine having already achieved it.

  B. Get help and support when you’re not feeling motivated.

  C. So remind yourself of why you’re doing what you’re doing.

  D. What kind of self-talk would you use to motivate yourself?

  E. Let them inspire you to access your own great desire within.

  F. You might feel proud, happy, satisfied, or any other emotion.

  G. Would you be able to properly train a dog without rewarding him?

    In the kitchen of my mother's houses there has always been a wooden stand with a small notepad and a hole for a pencil.

    I'm looking for paper on which to note down the name of a book I am recommending to my mother. Over forty years since my earliest memories of the kitchen pad and pencil,  five houses later,the current paper and pencil look the same as they always did. Surely it can't be the same pencil The pad is more modern, but the wooden stand is definitely the original one.

    "I'm just amazed you still have the same stand for holding the pad and pencil after all these years." I say to her, walking back into the living-room with a sheet of paper and the pencil. "You still use a pencil. Can't you afford a pen?"

    My mother replies a little sharply. "It works perfectly well, I've always kept the stand in the kitchen. I never knew when I might want to note down an idea, and I was always in the kitchen in these days.,

    Immediately I can picture her, hair wild, blue housecoat covered in flour, a wooden spoon in one hand, the pencil in the other, her mouth moving silently. My mother smiles and says, "One day I was cooking and watching baby Pauline, and I had a brilliant thought, but the stand was empty. One of the children must have taken the paper. So I just picked up the breadboard and wrote it all down on the back, It turned out to be a real breakthrough for solving the mathematical problem I Was working on."

    This story, which happened before I was born, reminds me how extraordinary my mother was,and is also a gifted mathematician. I feel embarrassed that I complain about not having enough child-free time to work. Later, when my mother is in the bathroom, I go into her kitchen and turn over the breadboards. Sure enough, on the back of the smallest one, are some penciled marks I recognize as mathematics. Those symbols have traveled unaffected through fifty years, rooted in the soil of a

cheap wooden breadboard, invisible exhibits at every meal.

As a little child,1 was always plump（胖的）.In college I started blowing up. It got out of control

when l went to law school.

    I'd made a decision a thousand times: I'm going to lose weight now. But what motivated（激发）

me to get serious about it was turning 30.1 weighed 414 pounds.1 was always tired. Some of my

family members have suffered from heart disease, and l was frightened. I also wanted to look better.

So after my birthday,1 walked into the office of a weight loss doctor.

    She was very understanding. Her focus was on balanced meals and she wanted me to exercise.

    Walking was all I could do at first. I started by walking a few blocks and gradually increased the

distance, until one weekend, I heard myself saying, "Wow, this seems pretty easy." So I started to run.

    1 was losing nine or ten pounds a month, and I had more energy. I started to think about the New

York City Marathon. For years,1 watched the runners and thought, "This looks like fun, but I could

never do that." But now I realized that maybe I could.I joined the New York Road Runners.I ran a

l0km, then a half marathon.I still wasn't confident I could run a full 26 miles. But I told myself I was

going to do it, no matter what.

    By my 33rd birthday,1 was down to 180 pounds. I started formally training for the marathon.

And on the morning of November l, I stood on the Verrazano Bridge in Staten Island with more than

40,000 0ther runners, waiting for the event to start.

    It was unbelievable to have the audience cheering me on, handing me cups of water. And I

crossed the finish line. My friends sprayed（向……喷射）me with beer, as if I'd won the Super Bowl.

And at that moment,I knew: If I set my mind to something, nothing is impossible.

Mark Rothko, one of the greatest painters of the twentieth century, was born in Daugavpils, Latvia in 1903. His family immigrated to the United States in 1913, after a 12-day voyage.

Mark moved to New York in the autumn of 1923 and found employment in the garment trade and settled down on the Upper West Side. It was while he was visiting someone at the Art Students League that he saw students painting a model. According to him, this was the start of his life as an artist. He was twenty years old and had taken some art lessons at school, so his initial experience was far from an immediate calling.

In 1936, Mark Rothko began writing a book, which he never completed, about the similarities in the children’s art and the work of modern painters. The work of modernists, which was influenced by primitive art, could, according to him, be compared to that of children in that “Child art transforms itself into primitivism, which is only the child producing a copy of himself.” In this same work, he said that “The fact that one usually begins with drawing is already academic. We start with colour.”

It was not long before his multiform developed into the style he is remembered for. In 1949 Rothko exhibited these new works at the Betty Parsons Gallery. For reviewer Harold Rosenberg, the paintings were unique and primitive. Rothko had, after painting his first multiform, separated himself from the world in East Hampton on Long Island, only inviting a very few people, including Rosenberg, to view the new paintings. The discovery of his works’ specialty came at a period of great sorrow: his mother Kate died in October 1948. As part of this new uniformity of artistic vision, his paintings no longer had individual titles. From this point on they were simply untitled, numbered or dated. However, to assist in distinguishing one work from another, traders would sometimes add the primary colours to the name. Additionally, for the next few years, Rothko painted in oil only on large vertical tents. This was done to surround the viewer, or, in his words, to make the viewer feel enveloped within the picture.

63. When did Rothko want to be an artist?

A. When he immigrated to the U.S.A.

B. When he watched students drawing.

C. When he moved to the Upper West Side.

D. When he joined the Art Students League.

64. What did Rothko think of modern art?

A. It could be produced by children.

B. It could be compared to child work.

C. It was a certain kind of primitive art.

D. It was academic from the very beginning.

65. Why does the author mention Rothko’s uncompleted book?

A. To prove Rothko’s concentration on painting.

B. To show Rothko’s research on the modern art.

C. To suggest Rothko’s unique personal painting style.

D. To explain the inspiration of Rothko’s painting style.

66. Rothko’s distinctive style ______.

A. took shape in 1948

B. was affected by Rosenberg

C. resulted from his boyhood experience                          

D. was rooted in the separation from the world

 My husband and I insisted that our children were old enough to clean their rooms and make their beds. But they thought  11 . My complaints, even self-justified shouting, were always landing on  12  ears. Very often a whole hour’s scolding would end with their  13  into tears, I felt very frustrated. I realized I needed to  14  my method of “mothering”.

    One day when they were at school, I spent some time  15  their rooms. On their desks, in plain  16 , I left the cards: “Dear Bill (the other card was  17  to Sarah), your room was messy this morning and I’m sure you like it clean. Love, the Room Fairy.”  18  arriving back, the children were  19  excited to receive the little note from the Room Fairy. The next day, their rooms were fairly tidy. Sure enough, there was another note from the Room Fairy __20  for them, thanking them for their nice “gift” of a clean room and  21  asking them to play a certain violin   22  . Each day, thank--you notes would be written differently to keep the ideas  23 .

    Sometimes the Room Fairy would propose a little  24 : “If you can finish your homework and  25   your lessons before dinner, I’ d like to watch a particular television program with you tonight.” Sometimes some colored markers or other little items would be left in  26  of well done jobs the day   27  .

      28  I can’t remember how long “the Room Fairy” continued leaving her love notes. When they were age appropriate, we used various versions of Post-Its(贴条). The bathroom mirror became the  29  centre of our home. Appointments, notices about visiting relatives, lesson schedules, and changes in plans could be posted.

    We all benefited from and  30  the idea of sharing reminders and daily details of life through notes. I believe the true advantage of the Room Fairy notes survives in our frequent and enjoyable communication.

  When I was 17, I met a famous doctor named Paul Bragg. He gave me one of the most valuable  26  of my life; a statement that was filled with words of  27 . To this very day, I still  28  it; I am a genius (天才) , and I apply my wisdom.

  29  ,I was a high school dropout (辍学学生) and was living in a tent in Hawaii. I had a very limited vocabulary and had never 30 reading a single book. When Dr Bragg taught me this statement, he held me to say it with feeling  31  it were true and present. To do so seemed so far away from 32  that it was funny. After saying it many times,  33  . I began to feel what those powerful words meant. 34 every day I continued to say it, and it became 35 to believe; I am a genius, and I apply my wisdom.

  It was two and a half years later when I really saw the 36 of the statement. I was sitting in a college library 37 by fellow students whom I was helping with higher mathematics. I heard one of the students speak  38  to another, “John is really a 39 ! At the moment, I 40 what Dr Bragg had taught me, and I 41 to say this statement for the rest of my life.

  I can’t quite put into words what a(n) 42 this statement has made in my life. 43 it, I was able to change from a dropout to the top of my college classes. I think that the key to 44 is putting your true feelings into a statement you  45  and saying it over and over every day.

 “A room without books is like a body without a soul,” observed the Roman philosopher, Cicero. It can also be a sign of financial problems to come. New research has uncovered a strong connection between the earning of adults and whether they grew up surrounded by books as children

Three economists at the University of Padua—Giorgio Brunello, Guglielmo Weber and Christoph Weiss—studied 6000 men born in nine European countries and concluded that children with access to books could expect to earn more money than those who grew up with few or no books.

They studied the period from 1920 to 1956, when school reforms saw the minimum school leaving age raised across Europe. They booked at whether, at the age of 10 , a child lived in a house with fewer than 10 books, a shelf of books, a bookcase with up to 100 books, two bookcases, or more than two bookcases.

Over the period studied, the research, published in The Economic Journal, found that an additional year of education increased a man’s average lifetime earnings by 9%. Men brought up in houses with less than a shelf of books earned only 5% more as a result of the extra year’s education, compared with 21% more for those who had access to a lot of books. Ands those who had access to books were more likely to move to the better-earning opportunities in cities than those without books. The men’s first job was also much more likely to be a white-collar job

The economists offer a number of theories for the results. “perhaps books matter because they encourage children to read more and reading can have positive effects on school performance,” they said.

The number of books in children’s homes can effectively predict their cognitive(认知的)test scores. This may indicate a home that encourages cognitive skills, which are important for economic success in life.
