Why do human beings still risk their lives under ground and doing one of the dirtiest and most dangerous jobs in the world?It’s an increasingly urgent question,given the recent high­profile(引人注目的) mining accidents in Sago,W.Va.and Huntington,Utah.A small group of engineers and robotics experts look forward to a day in the not­too­distant future when robots and other technology do most of the dangerous mining work.
Robotic technology,in particular,holds much promise,McAteer says,especially when it comes to mapping mines and rescuing trapped miners—the special operations of the mining industry.
One of the first mining robots was developed five years ago at Carnegie­Mellon University’s Robotics Institute.It was called Groundhog and it looked like a golf cart.It used lasers(激光器) to “see” in dark tunnels and map abandoned mines—some of the most dangerous work in the business.
The latest design is called Cave Crawler.It’s a bit smaller than Groundhog,and even more advanced.It can take photos and video and has sensors mounted(增加) that can detect the presence of dangerous gases.Incredibly,the robot has a real sense of logic.If it comes across an obstacle it gets confused.It has to think through the process and where to go next,and sometimes it throws_a_fit just like a real person.
The biggest obstacle,though,is cost.The original research project was federally funded,but that money has dried up,and it’s not clear where future funding will come from. Partly for that reason,and partly because of advances in safety,mining is not nearly as dangerous as it was in the past.Since 1990,fatalities(致命性) have declined by 67 percent and injuries by 51 percent,according to the National Mining Association.
Some experts predict that robots in mines will serve much of the same function that they do in the automotive industry.The robots do the most repetitive and dangerous jobs,but don’t eliminate(消除) the need for human workers.
小題1:The underlined phrase “throws a fit” in Paragraph 4 probably means “________”.
A.gets angryB.gets sick
C.becomes hungryD.becomes cheerful
小題2:We can infer from the last paragraph that ________.
A.robots in mines will serve much in the automotive industry
B.there will be no need for human workers in mines
C.the mine robots will have a very bright future
D.robots in mines have a long way to go
小題3:Which of the following is TRUE according to the text?
A.Mining robots do most of the mining work at present.
B.Groundhog can discover the presence of dangerous gases.
C.Experts are trying to make robots save miners in danger.
D.Robots cannot do dangerous work in dark areas.
小題4:What can be the best title for the text?
A.Mining Accidents in America
B.Could Robots Replace Humans in Mines?
C.Cave Crawler,the Latest Robot
D.The Development of Robots

Almost every machine with moving parts has wheels,yet no one knows exactly when the first wheel was invented or what it was used for.We do know,however,that they existed over 5,500 years ago in ancient Asia.
The oldest known transport wheel was discovered in 2002 in Slovenia.It is over 5,100 years old.Evidence suggests that wheels for transport didn’t become popular for a while,though.This could be because animals did a perfectly good job of carrying farming tools and humans around.
But it could also be because of a difficult situation.While wheels need to roll on smooth surfaces,roads with smooth surfaces weren’t going to be constructed until there was plenty of demand for them.Eventually,road surfaces did become smoother,but this difficult situation appeared again a few centuries later.There had been no important changes in wheel and vehicle design before the arrival of modern road design.
In the mid­1700s,a Frenchman came up with a new design of road—a base layer(層) of large stones covered with a thin layer of smaller stones.A Scotsman improved on this design in the 1820s and a strong,lasting road surface became a reality.At around the same time,metal hubs (the central part of a wheel)came into being,followed by the pneumatic tyre(充氣輪胎) in 1846.Alloy wheels were invented in 1967,sixty years after the appearance of tarmacked roads(柏油路).As wheel design took off,vehicles got faster and faster.                          (2013·重慶,C)
小題1:What might explain why transport wheels didn’t become popular for some time?
A.Few knew how to use transport wheels.
B.Humans carried farming tools just as well.
C.Animals were a good means of transport.
D.The existence of transport wheels was not known.
小題2:What do we know about road design from the passage?
A.It was easier than wheel design.
B.It improved after big changes in vehicle design.
C.It was promoted by fast­moving vehicles.
D.It provided conditions for wheel design to develop.
小題3:How is the last paragraph mainly developed?
A.By giving examples.
B.By making comparisons.
C.By following time order.
D.By making classifications.
小題4:What is the passage mainly about?
A.The beginning of road design.
B.The development of transport wheels.
C.The history of public transport.
D.The invention of fast­moving vehicles.

Global warming is when the earth heats up,the temperature rises.It happens when greenhouse gases—carbon dioxide,water vapor,nitrous oxide(二氧化氮),and methane(沼氣) trap heat and light from the sun in the earth’s atmosphere,which increases the temperature.This is like when heat is trapped in a car.On a very hot day,the car gets hotter when it is out in the parking lot.This is because the heat and light from the sun can get into the car,by going through the windows,but it can’t get back out.Once the light is inside the car,it is trapped and the heat builds up,just like it does in the earth’s atmosphere.This is what the greenhouse effect does to the earth.The heat and light can get through the atmosphere,but it can’t get out.As a result,the temperature rises.
Sometimes the temperature can change in a way that helps us.The greenhouse effect makes the earth appropriate for people to live on.Without it,the earth would be freezing,or on the other hand it would be burning hot.We would not get the sun’s heat and light to make the night somewhat warm.During the day,especially during the summer,it would be burning because the sun would be up with no atmosphere to filter(過濾) it,so people,plants,and animals would be exposed to all the light and heat.
Although the greenhouse effect makes the earth able to have people living on it,if there gets to be too many gases,the earth can get unusually warmer,and many plants,animals,and people will die.They would die because there would be less food (plants like corn,wheat,and other vegetables and fruits).This would happen because the plants would not be able to take in the heat.This would cause us to have less food to eat,but it would also limit the food that animals have.Gradually,people,plants,and animals would all die of hunger.
People are doing many things to try to stop global warming.One thing people are doing is carpooling.Carpooling is driving with someone to a place that you are both going to.This minimizes the amount of greenhouse gases put into the air by a car.
Another thing that people are doing is being more careful about leaving things turned on like the television,computer,and the lights.A lot of people are taking time away from the television,and instead,they are spending more time outdoors.This helps our planet out a lot.Now,more people are even riding buses,walking to school,and riding their bikes to lower the amount of greenhouse gases in the air.
Planting trees and recycling also help.If you recycle,less trash goes to the dump,and less trash gets burned.As a result,there are fewer greenhouse gases in our atmosphere.Although adults do many things to help stop global warming,kids can do just as much.
小題1:By the example given in Paragraph 1,the author wants to ________.
A.explain how greenhouse gases work
B.show his feeling in a car in hot summer
C.tell us cars are causes of greenhouse gases
D.say that there are greenhouse gases in every car
小題2:The underlined word “it” in Paragraph 2 refers to “________”.
A.lightB.heat
C.temperatureD.greenhouse effect
小題3:What is the main idea of Paragraph 3?
A.If there is greenhouse effect,all the plants will die.
B.Human beings are likely to disappear from the earth.
C.Crops can’t take the heat if there is greenhouse effect.
D.Although greenhouse effect is necessary,too much of it causes us to die.
小題4:What will the author most probably discuss in the paragraph that follows?
A.Why cars and buses pollute the air a lot.
B.What kids can do to help stop global warming.
C.What global warming is doing to the environment.
D.Who should be responsible for the environmental problems.

Electric cars are dirty.In fact,not only are they dirty,they might even be more dirty than their gasoline­powered cousins.
People in California love to talk about “zero­emissions vehicles”,but_people_in_California_seem_to_be_clueless_about_where_electricity_comes_from.Power plants mostly use fire to make it.Aside from the new folks who have their roofs covered with solar cells,we get our electricity from generators.Generators are fueled by something—usually coal,oil,but also by heat generated in nuclear power plants.There are a few wind farms and geothermal(地?zé)岬? plants as well,but by far we get electricity mainly by burning something.
In other words,those “zero­emissions” cars are likely coal­burning cars.It’s just because the coal is burned somewhere else that it looks clean.It is not.It’s as if the California Greens are covering their eyes—“If I can’t see it,it’s not happening.” Gasoline is an incredibly efficient way to power a vehicle;a gallon of gas has a lot of energy in it.But when you take that gas(or another fuel) and first use it to make electricity,you waste a nice part of that energy,mostly in the form of wasted heat—at the generator,through the transmission(傳送) lines,etc.
A gallon of gas may propel your car 25 miles.But the electricity you get from that gallon of gas won’t get you nearly as far—so electric cars burn more fuel than gas­powered ones.If our electricity came mostly from nukes;or geothermal,or hydro,or solar,or wind,then an electric car truly would be clean.But for political,technical,and economic reasons,we don’t use much of those energy sources.
In addition,electric cars’ batteries which are poisonous for a long time will eventually end up in a landfill.And finally,when cars are the polluters,the pollution is spread across all the roads.When it’s a power plant,though,all the junk is in one place.Nature is very good at cleaning up when things are too concentrated,but it takes a lot longer when all the garbage is in one spot.
小題1:What does the underlined part mean in Paragraph 2?
A.People see the California Greens everywhere.
B.People in California love to talk about zero­emissions vehicles.
C.People in California love to have their roofs covered with solar cells.
D.People in California have no idea that so far electricity mainly comes from burning coal,oil,etc.
小題2:What is the main idea of the text?
A.Electric cars are not clean at all.
B.Electric cars are better than gasoline­powered ones.
C.People cast doubts on electric cars’ batteries.
D.Gasoline is an efficient way to power a vehicle.
小題3:The electricity we get from a gallon of gas may make our car run ________.
A.not less than 25 miles
B.a(chǎn)s far as 50 miles
C.a(chǎn)s far as 25 miles
D.not more than 25 miles
小題4:It can be inferred from the text that ________.
A.being green is good and should be encouraged in communication
B.electric cars are not clean in that we get electricity mainly by burning something
C.zero­emissions vehicles should be chosen to protect our environment
D.electric cars are now the dominant vehicle compared with gasoline­powered cousins

When times get tough,we all look for ways to cut back.When we're hungry,we eat at home instead of going out.We take buses instead of taxis.And we wear our old designer jeans just a few months longer.With college expenses at all?time highs,high school students are eager to do anything to cut the cost of a university education.

One cost?cutting proposal is to allow college students to get a bachelor's degree in three years instead of four.Educational institutions have been actively exploring ways to make the learning process more efficient.But there's a question:Would the quality of undergraduate(本科生)education suffer? Few US universities have formally approved a “three?year degree”model.
I doubt that mainstream North American colleges will carry out a three?year curriculum(課程)any time soon.For one thing,most universities already allow highly qualified students to graduate early by testing out of certain classes and obtaining a number of college credits(學(xué)分).In addition,at famous universities,the committee who determine which courses are required and which courses are electives are unlikely to suddenly “throw out”one quarter of the required credits.Professors will resist “diluting(稀釋)”the quality of the education they offer.
In my opinion,a quality four?year education is always superior to a quality three?year education.A college education requires sufficient time for a student to become skilled in their major and do coursework in fields outside their major.It is not a good idea to water down education,any more than it's not a good idea to water down medicine.If we want to help students find their way through university,we should help them understand early on what knowledge and skills they need to have upon graduation.We should allow students to test out of as many courses as possible.We should give them a chance to earn money as interns(實習(xí)生)in meaningful part?time jobs that relate to their university studies,such as the five?year co?op program at Northeastern University.
小題1:The first paragraph serves as a(n) ________.
A.explanationB.definition
C.introductionD.comment
小題2:In most US universities,________.
A.college students are offered the co?op program
B.electives' credits make up one quarter of the required credits
C.a(chǎn)ll students are required to finish four?year education before graduation
D.some excellent students can graduate ahead of time
小題3:We can infer that ________.
A.the author is a college professor
B.the author thinks the cost of a university education is too high for people to afford
C.the author considers the university education quality very important
D.the author pays special attention to the all?round development of college students
小題4:Which of the following can be the best title?
A.It's time to shorten the learning process
B.Best learning takes place over time
C.University education should be watered down
D.College education calls for reform

During her junior year of high school, Diane Ray's teacher handed her a worksheet and instructed the 17-year-old to map out her future financial life. Ray pretended to buy a car, rent an apartment, and apply for a credit card.  Then, she and her classmates played the "stock market game", investing(投資) the hypothetical(虛擬的) earnings from their hypothetical jobs in the market in the disastrous fall of 2008. "Our pretend investments crashed," Ray says, still frightened. "We got to know how it felt to lose money."
That pain of earning and losing money is a feeling that public schools increasingly want to teach. Forty states now offer some type of financial instruction at the high-school level, teaching students how to balance checkbooks and buy stock in math and social-studies classes. Though it's too early to measure the full influence of the Great Recession(大蕭條), the interest in personal-finance classes has risen since 2007 when bank failures started to occur regularly. Now, many states including Missouri, Utah, and Tennessee require teenagers to take financial classes to graduate from high school. School districts such as Chicago are encouraging money-management classes for kids as young as primary school, and about 300 colleges or universities now offer online personal-finance classes for incoming students. "These classes really say, 'This is how you live independently,' " says Ted Beck, president of National Endowment for Financial Education.
Rather than teach investment methods or financial skills, these courses offer a back-to-the-basics approach to handling money: Don't spend what you don't have. Put part of your monthly salary into a savings account, and invest in the stock market for the long-term rather than short-term gains. For Ray, this means dividing her earnings from her part-time job at a fast-food restaurant into separate envelopes for paying bills, spending and saving.  "Money is so hard to make but so easy to spend," she says one weekday after school. "That is the big takeaway."
Teaching kids about the value of cash certainly is one of the programs' goals, but teachers also want students to think hard about their finances long term. It's easy for teenagers to get annoyed about gas prices because many of them drive cars. But the hard part is urging them to put off the instant satisfaction of buying a new T-shirt or an iPod. "Investing and retirement aren't things teenagers are thinking about. For them, the future is this weekend," says Gayle Whitefield, a business and marketing teacher at Uth’s Riverton High School.
That’s a big goal for these classes: preventing kids from making the same financial missteps their parents did when it comes to saving, spending, and debt. Though the personal savings rate has increased up to 4. 2 percent, that’s still a far distance from 1982, when Americans saved 11. 2 percent of their incomes. “It’s hard for schools to reach strict money-management skills when teenagers go home and watch their parents increase credit-card debt. It’s like telling your kids not to smoke and then lighting up a cigarette in front of them,” Beck says.
Even with these challenges, students such as Ray say learning about money in school is worthwhile. After Ray finished her financial class, she opened up a savings account at her local bank and started to think more about how she and her family would pay for college. “She just has a better understanding of money and how it affects the world,” says her mother, Darleen-and that’s sown to the details of how money is spent from daily expenses to various taxes. All of this talk of money can make Ray worry, she says, but luckily, she feels prepared to face it.
小題1:The “stock market game” mentioned in Paragraph 1 is meant to       .
A.introduce a new course to students
B.help students learn about investment
C.teach how to apply for a credit card
D.encourage students’ personal savings

Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experience? Strangely enough, the answer to these questions is yes. To some extent our intelligence is given to us at birth, and no amount of education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of person’s intelligence are fixed at birth, whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be intelligence. Thus if we take two unrelated people at random from population, it is likely that their degree of intelligence will be completely different. If, on the other hand, we take two identical twins, they will very probably be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degree of intelligence.
小題1: The writer is in favor of the view that man’s intelligence is given to him____________.
A.a(chǎn)t birth
B.through education
C.neither at birth nor through education
D.both at birth and through education
小題2:If a child is born with low intelligence, he can_____________________.
A.become a genius
B.still become a genius if he should be given special education
C.reach his intelligence limits in rich surroundings
D.not reach his intelligence in his life.
小題3:The example of the twins going to a university and to a factory separately shows_________.
A.the importance of their intelligence
B.the importance of their positions
C.the role of environment on intelligence
D.the part that birth plays

So long as teachers fail to distinguish between teaching and learning, they will continue to undertake to do for children that which only children can do for themselves. Teaching children to read is not passing reading on to them. It is certainly not endless hours spent in activities about reading. Douglas insists that “reading cannot be taught directly and schools should stop trying to do the impossible”.
Teaching and learning are two entirely different processes. They differ in kind and function. The function of teaching is to create the conditions and the climate that will make it possible for children to devise the most efficient system for teaching themselves to read. Teaching is also public activity. It can be seen and observed.
Learning to read involves all that each individual does to make sense of the world of printed language. Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public scrutiny.
If teacher and learner roles are not interchangeable, what then can be done through teaching that will aid the child in the quest(探索)for knowledge? Smith has one principal rule for all teaching instructions. “Make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children.”
When the roles of teacher and learner are seen for what they are, and when both teacher fulfill them appropriately, then much of the pressure and feeling of failure for both is eliminated. Learning to read is made easier when teachers create an environment where children are given the opportunity to solve the problem of leaning to read by reading.
小題1:The problem with the reading course as mentioned in the first paragraph is that ________.
A.it is one of the most difficult school courses
B.students spend endless hours in reading
C.reading tasks are assigned with little guidance
D.too much time is spent in teaching about reading
小題2:The teaching of reading will be successful if ________.
A.teachers can improve conditions at school for the students
B.teachers can enable students to develop their own way of reading
C.teachers can devise the most efficient system for reading
D.teachers can make their teaching activities observable
小題3:The underlined word“ scrutiny” most probably means“________”.
A.inquiryB.observationC.controlD.suspicion
小題4:According to the passage, learning to read will no longer be a difficult task when ________.
A.children become highly motivated
B.teacher and learner roles are interchangeable
C.teaching helps children in the search for knowledge
D.reading enriches children’s experience
小題5:The main idea of the passage is that ________.
A.teachers should do as little as possible in helping students learn to read
B.teachers should encourage students to read as widely as possible
C.reading ability is something acquired rather than taught
D.reading is more complicated that generally believed
