A
There are robot cleaners and robot mops to help us around the house, so why not a robot to build our houses? Wait no longer. Now there is a set of electronics to do just that, build a house from scratch, and fast.
Forget weeks to find a builder and months for house construction; a machine developed in the United States can build a 232 sqm house layer by layer in a single day. University of Southern California’s Professor Behrokh Khoshnevis has designed the giant robot that replaces construction workers with a mouth on an arm of crane, which spits out concrete and can quickly build a house according to a computer pattern. The technology, known as Contour (轮廓) Crafting, could revolutionize the construction industry. Contour Crafting could greatly decrease the cost of homeowning, making it possible for millions of displaced people to get on the property ladder. It could even be used in disaster relief areas to build emergency and replacement housing. As Prof Khoshnevis points out, if you look around you almost everything is made automatically these days—“your shoes, your clothes, home appliances, your car. The only thing that is still built by hand are these buildings. ”
The Contour Crafting system is a robot that automates age-old tools normally used by hand. These are applied by a robotic crane that builds a three-dimensional object. The nature of the technology means it will also be possible to create curved walls and architecture that is both “exotic (异国情调的) and beautiful” according to Prof Khoshnevis. As a result, it could be ideal to print out expensive houses according to customers’ demands.
Furthermore, Prof Khoshnevis believes that the technology could be applied beyond our planet. “Contour Crafting technology has the potential to build safe, reliable, and affordable structures, habitats, laboratories, and other facilities on the moon and Mars before the arrival of human beings, ”his website reads.
According to the International Labour Organization, construction employs nearly 110 million people worldwide and “plays a major role in fighting the high levels of unemployment and in absorbing extra labour from the rural areas”. What the implications are for builders is, of course, a major concern. But Khoshnevis says “the reality is that a lot of new jobs can be created in this field as well”. Instead of building the house, workmen are used to maintain the machine. 1. Which advantage does the giant robot have for the consumers? A. It saves a great deal of time.
B. It decorates houses beautifully.
D. It builds environmentally friendly houses.
C. It provides energy-saving apartments.
2. The underlined part “to get on the property ladder” (in Paragraph 3)means “ ”. A. to print objects
B. to purchase a house
C. to predict disasters
D. to accumulate wealth
3. The new construction technology can satisfy the needs of . A. low-income residents
B. people at different income levels
C. middle-income people
D. wealthy immigrants
4. What influence will Contour Crafting have on construction industry? A. Many construction workers will lose jobs.
B. Professionals will be hired to make robot builders. B
A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.
“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components(元件), ”said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own, ” he said. They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of inter-dependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to, ” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.
While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically it should be able to take off, land and fly around, ” he said.
Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead, ” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day-to-day basis. ”
5. According to the first paragraph, the robotic fly is . A. larger than a fat housefly
B. as large as a fat housefly C. smaller than a fat housefly
D. as large as a butterfly
D. Construction workers will update their skills.
C. More rural people will engage in construction.
6. The difficulty the team of engineers met with while making the robotic fly was that .
A. they had no model in their mind
B. they did not have sufficient time D. they could no assemble the components
C. they had no ready-made components
7. It can be inferred from paragraphs 3 and 4 that the robotic fly . A. consists of a flight device and a control system C. can collect information from many sources
B. can just fly in limited areas at the present time D. has been put into wide application
8. Which of the following can be learned from the passage?
A. The robotic flyer is designed to learn about insects. B. Animals are not allowed in biological experiments. C. There used to be few ways to study how insects fly. 七选五
C
D. Wood’s design can replace animals in some experiments.
Interruptions are one of the worst things to deal with while you’re trying to get work done. 1 , there are several ways to handle things. Let’s take a look at them now.
2 . Tell the person you’re sorry and explain that you have a million things to do and then ask if the two of you can talk at a different time.
When people try to interrupt you, have set hours planned and let them know to come back during that time or that you’ll find them then. 3 . It can help to eliminate(消除) future interruptions.
When you need to talk to someone, don’t do it in your own office. 4 , it’s much easier to excuse yourself to get back to your work than if you try to get someone out of your space even after explaining how busy you are.
If you have a door to your office, make good use of it. 5 . If someone knocks and it’s not an important matter, excuse yourself and let the person know you’re busy so they can get the hint(暗示) that when the door is closed, you’re not to be disturbed.
A. If you’re busy, don’t feel bad about saying no B. When you want to avoid interruptions at work C. Set boundaries for yourself as far as your time goes D. If you’re in the other person’s office or in a public area E. It’s important that you let them know when you’ll be available F. It might seem unkind to cut people short when they interrupt you G. Leave it open when you’re available to talk and close it when you’re not
D Memory
Memory is the process of storing experiences in the brain and recalling them later. People use their memories during every moment of their lives. 6 Even to walk or to eat, people remember the movements they learned as children.
Scientists know that memories cause chemical changes in the neurons (神经元) (nerve cells) in the brain. The chemical changes create what are called memory paths. These paths can remain in the brain for seconds or for a person's entire life.
Many scientists believe that there are two levels of memory. 7 The other is long-term memory, or permanent memory. Short-term memory is a way to store information temporarily. It lasts about 15 to 30 seconds. An example is keeping a telephone number in mind after looking it up and while dialing.
8 It can last days, months, years, or a lifetime. Repeating and practicing motions (动作) or tasks help the brain to store information for a long time. If a person dials a telephone number many times, the number will move from short-term to long-term memory.
Scientists also think that there are different types of memory. These include motor-skill, factual, and emotional memory. Motor-skill memory tells people how to do physical things that they have done before. It can be short-term or long-term. 9 Factual memory is the storage of facts. It can be short-term or long-term. Factual memory lets people remember faces, numbers, and the experiences that happen to them.
10 It is long-term. For example, people tend to remember very frightening experiences throughout their lives. Some scientists think this happens so that people are prepared for problems in the future. A. Emotional memory is the memory of emotions. B. One level is short-term memory, or working memory. C. They must remember words and ideas to speak or to write. D. It's easier to remember a poem that rhymes than one that doesn't. E. Long-term memory is the storage of information for longer periods. F. People use motor-skill memory to copy a dance step and to ride a bicycle.
G. People can pull out information stored in memory through either recall or recognition. 六、完形填空：
A Person Who Has Influenced My Life
There is always a time in one’s life when a hero comes along. Someone who has inspired you can really help you learn what life is about.
I _1_ it as if it was yesterday. I was fifteen years old that year. It was around eight o’clock one evening when my mother _2_ a phone call from her brother-in-law, who told us my aunt was in hospital and that the doctor _3_ them she would need an operation immediately. My family became very _4_ about my aunt’s situation.
While my aunt was in the hospital with special _5_, my cousin Mark, who is mentally disabled, spent time with my family. Mark was seventeen at the time, and had been born with severe mental disorders, which _6_ a wide range of social and physical problems for him throughout everyday life.

Now looking back at it saddens me to see the _10_ I once showed.
Over the two weeks when Mark lived with my family, I probably _11_ more about life and its meanings. Thinking back, I took _12_in daily life for granted, believing it would always be there. I never even thought about being able to do things like walking, brushing my teeth, or going to the bathroom on my own. Now I see how _13_ I am to be able to do these things independently.
Mark was seventeen, but learned on a nine-year-old _14_. Although his learning ability was slower than most, he could still learn. He explored _15_ to do most of the things everyone else did. _16_ he did pretty well and succeeded in almost everything he tried to do. He _17_ his illness and showed an ambition to love life. To him, having a successful life means achieving goals on his own terms and at his own _18_.
Mark is my hero, for his disability has forever _19_ my viewpoint on life. It seems like a well-deserved life when you’re fifteen, and it is amazing how in a period of time your point of view can change so _20_.
