One morning when I was 11, I explored the town’s abandoned round grain barn（谷仓）. I found a chained sliding door that was wide enough for me to pass through.
Inside, there was a heavy smell of dead mice in the dark. After my eyes adjusted, I noticed a shaft (升降机井) that rose all the way to the top of the barn. On one side was a one-man elevator with a long rope and roller.
I stepped onto the platform and gave the rope a drag and the elevator began sliding up the shaft, but stopped halfway. After a brief panic attack, I noticed holes in the wall at regular intervals, forming a ladder. For reasons known only to an 11-year-old, I decided it would be better to go up than down. So, with shaking hands, I began climbing the wall.
After what seemed like forever, I reached the top of the shaft. I stood up, dusted myself off and found…absolutely nothing of interest. It was just an empty room with a ladder leading up to the roof. I climbed all the way up here for this? Then I noticed a fire extinguisher（灭火器）,which I’d always wanted to shoot off. So this was the chance of a lifetime. I tried it, and, much to my surprise, the thing worked! It shot out a thick cloud of powder that instantly filled the room. I couldn’t breathe. I was going to choke to death, and they’d probably never even find my body.
Luckily, I remembered the ladder to the roof. I climbed up, popped the straw roof and saw a bright blue sky.
I suddenly realized the dust and powder pouring out of the top could draw attention. So when the dust had settled, I climbed down and slipped out of the chained door. I’m not sure if I was more excited about being alive or about not being caught, but I ran all the way back home.When the author got inside the barn, he _______.

Space is where our future is — trips to the Moon, Mars and beyond. Most people would think that aside from comets(彗星) and stars, there is little else out there. But, since our space journey started we have left so much trash（垃圾） there that scientists are now concerned that if we don't clean it up, we may all be in mortal （致命的）danger.
The first piece of space junk was created in 1964, when the American satellite Vanguard I stopped operating and lost its connection with the ground center. However, since it kept orbiting around the Earth without any consequences, scientists became increasingly comfortable abandoning（抛弃） things that no longer served any useful purpose in space.
It is estimated （估计）that there are now over 500,000 pieces of man-made trash orbiting the Earth at speeds of up to 17,500 miles per hour. The junk varies from tiny pieces of paint chipped off rockets to cameras, huge fuel tanks, and even odd items like the million-dollar tool kit that astronaut Heidemarie Stefanyshyn Piper lost during a spacewalk.
The major problem with the space trash is that it may hit working satellites and damage traveling spacecraft(飞船). Moreover, pieces of junk may collide（碰撞） with each other and break into pieces which fall back to the Earth. To avoid this, scientists have invented several ways for clearing the sky. Ground stations have been built to monitor larger pieces of space trash to prevent them from crashing into working satellites or space shuttles. Future plans include a cooperative effort among many nations to stop littering in space and to clean up the trash already there.What was the first piece of man-made space trash?
| A．A camera. | B．A tool kit. |
| C．A fuel tank. | D．A broken satellite. |
Why were scientists NOT concerned about space trash in the beginning?
| A．It no longer served any useful purpose. |
| B．It was millions of miles away from the Earth. |
| C．It did not cause any problems. |
| D．It was regarded as similar to comets and stars. |
Which of the following statements is true about space junk?
| A．It is huge, heavy machines. |
| B．It never changes position. |
| C．It floats slowly around the Earth. |
| D．It may cause problems for space shuttles. |
What has been done about the space trash problem?
| A．Scientists have cleaned up most of the trash. |
| B．Large pieces of space trash are being closely watched. |
| C．Many nations have worked together to stop polluting space. |
| D．Ground stations are built to help store the trash properly in space. |
Choosing the Right Resolution (决定)
Millions of Americans began 2014 with the same resolution they started 2013 with, a goal of losing weight. However, setting weight loss as a goal is a mistake.
To reach our goal of losing weight --- the output, we need to control what we eat --- the input ( 输入). That is, we tend to care about the output but not to control the input. This is a bad way to construct goals. The alternative is to focus your resolution on the input. Instead of resolving to lose weight, try an actionable resolution: “I’ll stop having desert for lunch,” or “I’ll walk every day for 20 minutes.” Creating a goal that focuses on a well-specified input will likely be more effective than concentrating on the outcome.
Recently a new science behind incentives (激励) , including in education, has been discussed. For example, researcher Roland Fryer wanted to see what works best in motivating children to do better in school. In some cases, he gave students incentives based on input, like reading certain books, while in others, the incentives were based on output, like results on exams. His main finding was that incentives increased achievement when based on input but had no effect on output. Fryer’s conclusion was that the intensives for inputs might be more effective because do not know how to do better on exam, aside from general rules like “study harder.” Reading certain books, on the other hand, is a well-set task over which they have much more control.
As long as you have direct control over your goal, you have a much higher chance of success. And it’s easier to start again if you fail, because you know exactly what you need to do.
If you want to cut down on your spending, a good goal would be making morning coffee at home instead of going to a cafe, for example. This is a well-specified action-based goal for which you can measure your success easily. Spending less money isn’t a goal because it’s too general. Similarly, if you want to spend more time with your family, don’t stop with this general wish. Think about an actionable habit that you could adopt and stick to, like a family movie night every Wednesday.
In the long run, these new goals could become a habit.The writer thinks that setting weight loss as a goal is a mistake because _______ .
| A．it is hard to achieve for most Americans |
| B．it is focused too much on the result |
| C．it is dependent on too many things |
| D．it is based on actionable decisions |
In Roland Fryer’s research, some students did better than the others because ______ .
| A．they obeyed all the general rules |
| B．they paid more attention to exams |
| C．they were motivated by their classmates |
| D．they were rewarded for reading some books |
According to the writer, which of the following statements is a good goal?
| A．“I’ll give up desert.” |
| B．“I’ll study harder.” |
| C．“I’ll cut down my expense” |
| D．“I’ll spend more time with my family” |
The writer strongly believes that we should ________ .
| A．develop good habits and focus on the outcome |
| B．be optimistic about final goals and stick to them |
| C．pick specific actions that can be turned into good habits |
| D．set ambitious goals that can balance the input ang output |
However wealthy we may be, we can never find enough hours in the day to do everything we want. Economics deals with this problem through the concept of opportunity cost, which simply refers to whether someone’s time or money could be better spent on something else.
Every hour of our time has a value. For every hour we work at one job we could quite easily be doing another, or be sleeping or watching a film. Each of these options has a different opportunity cost—namely, what they cost us in missed opportunities.
Say you intend to watch a football match but the tickets are expensive and it will take you a couple of hours to get to and from the stadium. Why not, you might reason, watch the game from home and use the leftover money and time to have dinner with friends? This—the alternative use of your cash and time—is the opportunity cost.
For economists, every decision is made by knowledge of what one must forgo—in terms of money and enjoyment—in order to take it up. By knowing precisely what you are receiving and what you are missing out on, you ought to be able to make better-informed, more reasonable decisions. Consider that most famous economic rule of all: there’s no such thing as a free lunch. Even if someone offers to take you out to lunch for free, the time you will spend in the restaurant still costs you something in terms of forgone opportunities.
Some people find the idea of opportunity cost extremely discouraging: imagine spending your entire life calculating whether your time would be better spent elsewhere doing something more profitable or enjoyable. Yet, in a sense it’s human nature to do precisely that—we assess the advantages and disadvantages of decisions all the time.
In the business world, a popular phrase is “value for money.” People want their cash to go as far as possible. However, another is fast obtaining an advantage: “value for time.” The biggest restriction on our resources is the number of hours we can devote to something, so we look to maximize the return we get on our investment of time. By reading this passage you are giving over a bit of your time which could be spent doing other activities, such as sleeping and eating. In return, however, this passage will help you to think like an economist, closely considering the opportunity cost of each of your decisions.According to the passage, the concept of “opportunity cost” is applied to ________.
| A．making more money |
| B．taking more opportunities |
| C．reducing missed opportunities |
| D．weighing the choice of opportunities |
The “leftover ... time” in Paragraph 3 probably refers to the time ________.
| A．spared for watching the match at home |
| B．taken to have dinner with friends |
| C．spent on the way to and from the match |
| D．saved from not going to watch the match |
What are forgone opportunities?
| A．Opportunities you forget in decision-making. |
| B．Opportunities you give up for better ones. |
| C．Opportunities you miss accidentally. |
| D．Opportunities you make up for. |
Last summer, two nineteenth-century cottages were rescued from remote farm fields in Montana, to be moved to an Art Deco building in San Francisco. The houses were made of wood. These cottages once housed early settlers as they worked the dry Montana soil; now they hold Twitter engineers.
The cottages could be an example of the industry’ s odd love affair with “low technology,” a concept associated with the natural world, and with old-school craftsmanship (手艺) that exists long before the Internet era. Low technology is not virtual (虚拟的)—so, to take advantage of it, Internet companies have had to get creative. The rescued wood cottages, fitted by hand in the late eighteen-hundreds, are an obvious example, but Twitter’s designs lie on the extreme end. Other companies are using a broader interpretation (阐释) of low technology that focuses on nature.
Amazon is building three glass spheres filled with trees, so that employees can “work and socialize in a more natural, park-like setting.” At Google’s office, an entire floor is carpeted in glass. Facebook’s second Menlo Park campus will have a rooftop park with a walking trail.
Olle Lundberg, the founder of Lundberg Design, has worked with many tech companies over the years. “We have lost the connection to the maker in our lives, and our tech engineers are the ones who feel impoverished (贫乏的) , because they’re surrounded by the digital world,” he says. “They’re looking for a way to regain their individual identity, and we’ve found that introducing real crafts is one way to do that.”
This craft based theory is rooted in history, William Morris, the English artist and writer, turned back to pre-industrial arts in the eighteen-sixties, just after the Industrial Revolution. The Arts and Crafts movement defined itself against machines. “Without creative human occupation, people became disconnected from life,” Morris said.
Research has shown that natural environments can restore(恢复) our mental capacities. In Japan, patients are encouraged to “forest-bathe,” taking walks through woods to lower their blood pressure.
These health benefits apply to the workplace as well. Rachel Kaplvin, a professor of environmental psychology, has spent years researching the restorative effects of natural environment. Her research found that workers with access to nature at the office—even simple views of trees and flowers—felt their jobs were less stressful and more satisfying. If low-tech offices can potentially nourish the brains and improve the mental health of employees then, fine, bring on the cottages.The writer mentions the two nineteenth-century cottages to show that ________.
| A．Twitter is having a hard time |
| B．old cottages are in need of protection |
| C．early settlers once suffered from a dry climate in Montana |
| D．Internet companies have rediscovered the benefits of low technology |
Low technology is regarded as something that _______.
| A．is related to nature |
| B．is out of date today |
| C．consumes too much energy |
| D．exists in the virtual world |
The main idea of Paragraph 5 is that human beings ________.
| A．have destroyed many pre-industrial arts |
| B．have a tradition of valuing arts and crafts |
| C．can become intelligent by learning history |
| D．can regain their individual identity by using machines |
The writer’s attitude to “low technology” can best be described as ________.
| A．positive | B．defensive |
| C．cautious | D．doubtful |
What might be the best title for the passage?
| A．Past Glories, Future Dreams |
| B．The Virtual World, the Real Challenge |
| C．High-tech Companies, Low-tech Offices |
| D．The More Craftsmanship, the Less Creativity |
I was never very neat, while my roommate Kate was extremely organized. Each of her objects had its place, but mine always hid somewhere. She even labeled（贴标签）everything. I always looked for everything. Over time, Kate got neater and I got messier. She would push my dirty clothing over, and I would lay my books on her tidy desk. We both got tired of each other.
War broke out one evening. Kate came into the room. Soon, I heard her screaming. “Take your shoes away! Why under my bed!” Deafened, I saw my shoes flying at me. I jumped to my feet and started yelling. She yelled back louder.
The room was filled with anger. We could not have stayed together for a single minute but for a phone call. Kate answered it. From her end of the conversation, I could tell right away her grandma was seriously ill. When she hung up, she quickly crawled（爬）under her covers, sobbing.
Obviously, that was not something she should not go through alone. All of a sudden, a warm feeling of sympathy rose up in my heart.
Slowly, I collected the pencils, took back the books, made my bed, cleaned the socks and swept the floor, even on her side. I got so into my work that I even didn’t notice Kate had sat up. She was watching, her tears dried and her expression one of disbelief. Then, she reached out her hands to grasp mine. I looked up into her eyes. She smiled at me, “Thanks.”
Kate and I stayed roommates for the rest of the year. We didn’t always agree, but we learned the key to living together: giving in, cleaning up and holding on.What made Kate so angry one evening?
| A．She couldn’t find her books. |
| B．She heard the author shouting loud. |
