Particles from car exhausts generate more persistent clouds but less rain, new research suggests. Furthermore, putting more of these particles into the atmosphere reduces the low-level winds, which could reduce the amount of wind power available in very polluted regions. The dry but populated regions may therefore suffer a triple blow as a result of vehicle pollution:less water, less hydropower and less wind energy.
Scientists studied the effects of aerosol(浮质)pollution from cars and industry. They correlated satellite data on wind speeds and the amount of aerosol particles in the atmosphere above the South Coast Basin in California and above China. Results showed that higher concentrations of aerosols were closely associated with slower ground winds. Scientists then used computer models to support the idea that there was a cause and effect relationship behind this correlation.
Particles floating in the atmosphere block energy from the Sun, preventing it from warming the surface of the Earth. Cooler surface temperatures during the day means the low—level and slow moving air does not rise up and mix with the faster winds at higher altitudes. Slower winds also induce less evaporation from oceans, rivers and lakes. And finally, once clouds have formed, they store less moisture in the form of rain. This is because raindrops form around small particles— dust, for instance, or pollution. With more particles in the atmosphere, it takes longer for enough water to condense(凝结)onto a particle to form a raindrop. And if the cloud of fine droplets(小滴)moves to a drier area before its would-be rain can rail, the moisture evaporates once more and the cloud disappears.
Scientists note their new work does not contradict previous findings that suggest global warming might lead to more tropical storms, because there is far less particulate(微粒的)pollution over the oceans.
60. The first paragraph mainly talks about .
A. the results of vehicle pollution
B. an introduction to particles from car exhausts
C. less wind energy in polluted regions
D. less water caused by vehicle pollution
61. From this passage we can learn that .
A. scientists supported their idea by using material models
B. the new study is contrary to the previous findings
C. if there are more particles in the atmosphere, there will be more raindrops
D. there is a cause and effect relationship between wind speeds and particle pollution
62. The underlined word “induce” in Paragraph 3 most probably mean _ .
A. reduce B. persuade C. cause D. produce

As motorways become more and more blocked up with traffic, a new generation on flying cars will be needed to ferry people along skyways. That is the conclusion of engineers from the US space agency and aeronautical firms, who envision future commuters traveling by “skycar”.
These could look much like the concept skycar shown in the picture, designed by Boeing research and development. However, such vehicles could be some 25 years from appearing on the market. Efforts to build flying vehicles in the past have not been very successful. Such vehicles would not only be expensive and require the skills of a trained pilot to fly, but there are significant engineering challenges involved in developing them. “When you try to combine them you get the worst of both worlds: a very heavy, slow, expensive vehicle that’s hard to use,” said Mark Moore, head of the personal air vehicle(PAV) division of the vehicle systems program at Nasa’s Langley Research Center in Hampton, US. But Boeing is also considering how to police the airways-and prevent total pandemonium(吵杂狂乱的喧闹)-if thousands of flying cars enter the skies.
“The neat, gee-whiz part is thinking about what the vehicle itself would look like,” said Dick Paul, a vice president with Phantom Works, Boeing’s research and development arm. “But we’re trying to think through all the consequences of what it would take to deploy(散开) a fleet of these.”
Past proposals to solve this problem have included artificial intelligence systems to prevent collisions between air traffic. Nasa is working on flying vehicles with the initial goal of transforming small plane travel. Small planes are generally costly, loud, and require months of training and lots of money to operate, making flying to work impractical for most people. But within five years, Nasa researchers hope to develop technology for a small plane that can fly out of regional airports, costs less than $100,000(£55,725), is as quiet as a motorcycle and as simple to operate as a car.
Although it would not have any road-driving capabilities, it would bring this form of travel within the grasp of a wider section of people. The new technology would automate many of the pilot’s functions. This Small Aircraft Transportation System(Sats) would divert pressure away from the “hub-and-spoke(中心辐射型)” model of air travel. Hub-and-spoke refers to the typically US model of passengers being processed through large “hub” airports and then on to secondary flights to “spoke” airports near their final destinations.
1.The best title for this text would be ________.
A.Developing Skycars | B.The Traffic Jams in the Sky |
C.How to Guide Flying Cars in the Sky | D.What Flying Cars Will Look Like |
2. The underlined word “envision” in Paragraph 1 most probably means “________”.
A.see | B.expect | C.think | D.announce |
3.When engineers develop the skycars, they have to deal with the following difficulties except ________.
A.how to fly out of regional airports |
B.how to prevent the disorder of the airways |
C.how to reduce expenses and the vehicle’s weight |
D.how to fly the skycars to enter skies |
4. Now Nasa researchers’ aim is to ________.
A.make big flying cars |
B.work out the plan——how to transform small plane travel |
C.develop a new kind of small plane different from the traditional one |
D.build a new kind of small plane with road-driving abilities |

Feeling exhausted and hopeless, I began walking to my car. Every step seemed tiring, and every step was another to survive. As I looked up into the sky I thought about how my grandmother had left me, and my anger began to return. I was annoyed by the loss, and my belief in God was beginning to fade. I couldn’t understand why these things happened. So as I stood in a public parking lot a million questions formed in my mind. Why did this happen to me? Aren’t we supposed to get signs from the people that pass on? Why did I not feel her presence anymore? Is there a heaven?
Suddenly, a woman driving right by my side rolled down her window and distracted my unanswered thoughts. “Excuse me, excuse me, excuse me,” she said loudly. Thinking she was going to ask for my parking spot, I simply pointed to my car. The thought of having to say where my car was seemed like too much to bear. “No, excuse me,” she said again.
At this point, I felt I had no choice but to see what this annoying lady wanted. As I got closer, I was startled—was this my grandmother’s nurse, Adu, who lived with her during her final months? I soon realized that she wasn’t, although the resemblance was unusual. Then, I realized that this Adu was searching for something in her bag. Surprisingly, I was overcome by a sense of relief that led me to be patient the entire time the lady was searching. Others would be nervous by a stranger reaching in their bag, but I wasn’t. She finally reached to the very bottom of her bag and handed me a three-page booklet. “It looks like you need this,” she said calmly with a warm smile on her face.
I looked down at the mysterious and obviously used booklet and on the front cover in big bold letters read “What Hope for Dead Loved Ones?”
It took me only a few seconds to comprehend the exchange with this woman, but by the time I looked up, she was gone.
I walked slowly into my car holding the tiny little book that was given to me with fear that it would fly away in the wind. I didn’t know what it was exactly, but I knew that if my grandmother had anything to do with that I didn’t want to let it go.
I felt a sense of relaxation as I opened the first page. It explained how people pass on, but their spirit remains with us. This was the first time since my grandma had passed that I felt her with me, just like I had wanted. I didn’t know whether to laugh or cry, but I did know that I finally felt happiness from the surprising change in events.
I couldn’t, and still can’t, believe what had happened to me on that day. I don’t remember the specific details that you usually hear about like what the person was wearing, the time of day, or even the weather, but it doesn’t matter. It was a random day in November when my life turned back around and I began to feel hope again. It was real. It was a miracle. And, I’ll remember it for the rest of my life.

Failure is probably the most exhausting experience a person ever has. There is nothing more tiring than not succeeding.
We experience this tiredness in two ways: as start-up fatigue(疲惫) and performance fatigue. In the former case, we keep putting off a task because it has either too boring or too difficult. And the longer we delay it, the more tired we feel.
Such start-up fatigue is very real, even if not actually physical, not something in our muscles and bones. The solution is obvious though perhaps not easy to apply: always handle the most difficult job first.
Years ago, I was asked to write 102 essays on the great ideas of some famous authors. Applying my own rule, I determined to write them in alphabetical(按字母顺序), never letting myself leave out a tough idea. And I always started the day’s work with the difficult task of essay-writing. Experience proved that the rule works.
Performance fatigue is more difficult to handle. Though willing to get started, we cannot seem to do the job right. Its difficulties appear so great that, however hard we work, we fail again and again. In such a situation, I work as hard as I can-then let the unconscious take over.
When planning Encyclopaedia Britannica (《大英百科全书》), I had to create a table of contents based on the topics of its articles. Nothing like this had ever been done before, and day after day I kept coming up with solutions, but none of them worked. My fatigue became almost unbearable.
One day, mentally exhausted, I wrote down all the reasons why this problem could not be solved. I tried to convince myself that the trouble was with the problem itself, not with me. Relived, I sat back in an easy chair and fell asleep.
An hour later, I woke up suddenly with the solution clearly in mind. In the weeks that followed, the solution which had come up in my unconscious mind provided correct at every step. Though I worked as hard as before, I felt no fatigue. Success was now as exciting as failure had been depressing.
Human beings, I believe must try to succeed. Success, then, means never feeling tired.
1.People with start-up fatigue are most likely to ________.
A.delay tasks B.work hard
C.seek help D.accept failure
2.What does the author recommend doing to prevent start-up fatigue?
A.Writing essays in strict order.
B.Building up physical strength.
C.Leaving out the toughest ideas.
D.Dealing with the hardest task first.
3.On what occasion does a person probably suffer from performance fatigue?
A.Before starting a difficult task.
B.When all the solutions fail.
C.If the job is rather boring.
D.After finding a way out.
4.According to the author, the unconscious mind may help us ________.
A.ignore mental problems B.get some nice sleep
C.gain complete relief D.find the right solution
5.What could be the best title for the passage?
A.Success Is Built upon Failure
B.How to Handle Performance Fatigue
C.Getting over Fatigue: A Way to Success
D.Fatigue: An Early Sign of Health Problems
