C
A car that runs on coffee is unveiled（shown to the public for the first time）today but at between 25 and 50 times the cost of running a car on petrol, the invention won’t please any motor industry accountants．
Nicknamed the Car-puccino, it has been created using a 1988 Volkswagen Scirocco bought for £400 and it was chosen because it looked like the time-traveling DeLorean in the movie Back To The Future．The car will be driven the 210 miles between Manchester and London powered only by roasted coffee granules （颗粒）．It has been built by a team from the BBC1 science programme Bang Goes The Theory and will go on display at the Big Bang science fair in Manchester to show how fuels other than traditional petrol can power vehicles．
The team calculates the Car-puccino will do three miles per kilo of ground coffee （咖啡粉） — about 56 cups of espressos （浓咖啡） per mile．The journey will use about 70 kilos of ground coffee which, at supermarket prices of between £13 and £26 a kilo depending on brand and quality, will cost between £910 and £1,820, or between 25 and 50 times the £36 cost of petrol for the journey．In total, the trip will cost 11,760 espressos, and the team will have to take ‘coffee breaks’ roughly every 30 to 45 miles to pour in more granules．They will also have to stop about every 60 miles to clean out the ‘coffee filters’ to rid them of the soot and tar which is also generated by the process．So despite a top speed of 60mph, the many stops mean the going will be slow, with the journey taking around ten hours．
Sadly, the inventors will still have to pay duty on their coffee fuel---even though tax collectors at Her Majesty’s Revenue and Custom haven’t yet worked out how much．
Nick Watson, producer of Bang Goes The Theory, said, “Coffee, like wood or coal, has some carbon content so you can use it as a fuel．The coffee needs to be very dry and in granules to allow the air to move through the pile of coffee as it burns．The brand doesn’t matter．” He said the same technology could be used to power a car on other unusual fuels, such as woodchips or nut shells, construction or agricultural waste．
49．Which is the right way to choose the coffee used as fuels to run the Car-puccino?
A．It should be very dry． B．The stronger, the better．
C．The smaller the granules are, the better． D．It should be of a certain brand．
50．What can be inferred from the passage?
A．All kinds of materials can be used as fuels．
B．The Car-puccino will be put into the market soon．
C．Nick Watson is the designer of the Car-puccino
D．Much remains to be improved for the Car-puccino．
51．The Car-puccino has its disadvantages EXCEPT that ________．
A．it makes a lot of noise
B．it runs at a very high cost
C．it has to stop to be refueled very often．
D．it’s not good enough for long-distance journey
52．How much ground coffee will be used to cover a distance of 126 miles in this car?
A．About 70 kilos B．About 42 kilos． C．About 32 kilos D．About 30 kilos |

Memories of highly charged events, like the London bombings of the 7th July 2005, can be inaccurate and should not be relied on in court, according to a study in Britain. People can create false memories, bringing problems for police investigations.
The simultaneous (同时) bombings of three underground trains and a double－decker bus in London some years ago are imprinted on the minds of many people in Britain.
But our memories of the attacks are unreliable, according to a study from Portsmouth University. Forty percent of British students questioned about the events remembered seeing a film recorded by a CCTV(闭路监控) camera that shows a particular event of the bus bomb——footage(片段) which never existed. A further 28% claimed to have seen a non－existent computerized reconstruction.
Some even recalled specific details of the attack, which none of them witnessed. "The bus had just stopped to let people off when two women and a man got on," said one. "He placed a hag by his side, the woman sat down and as the bus left, there was an explosion. There was a leg on the floor." Another described how the bus had stepped at a traffic light when there was a bright light, an explosion and the roof of the bus was blown off by the power of the explosion.
"Memories are not like videotape you can return to the beginning and replay for perfect recall," said lead researcher James Ost. "Because of this, they are not reliable enough to form the basis of legal decisions." He believes people who are more creative might be more inclined to make these kinds of errors.
60．According to the passage, when people are strongly affected by an event______.
A．all they say about the event is not true
B．they couldn"t remember anything
C．they couldn"t go on the court to be witnesses
D．they couldn"t make any errors on what they see about the event
61．The third paragraph______.
A．tells us what some people saw about the attack
B．shows that some people did create some false memories
C．shows that the London bombing was indeed a terrorist attack
D．shows that some people could remember details of an event
62．The underlined word "inclined" in the last paragraph is closest to the meaning of______.
A．careful B．likely C．serious D．curious
63．What is mainly discussed in the passage?
A．How our memories work. B．False memories.
C．How to avoid false memories. D．What can be done to memories. |

Manage your time well for each module(单元), but also make sure you get a good balance between work and social life. That is vital for life in general.
Set aside time specifically for each subject. Try to study one subject a day. You need to balance time. If you are bad at balancing things, make a personal timetable. Even if you do not stick to it, you will have an idea what you should be doing each day. This is better than trying to do everything each day and, at the end of the week, not achieve anything. Also, try to keep your weekends free of studying. Only study at the weekend if you really have to.
I had to learn to balance work, study and family when I was at college. I was a retail assistant working part-time and had at least four modules to complete at the same time at college. I also had to help around the house doing household cleaning and shopping at times. I managed to finish my college work on time, which was very difficult and hard, and still hold down a job.
Why was it possible? Because I only thought about my part-time work when I was at work on the weekends and my college work had to be done from Mondays to Fridays before the weekends. This was hard—but you need to set a timetable for yourself. It was an achievement when I finally realized that things have to be done in order, and need to be organized as well.
Balancing study and other aspects(方面) of your life can be a problem if you have a job or a family, but planning in advance is helpful. Use the time you have well. Do not leave anything until the last minute, as this will only cause problems.
55.The underlined word“vital”(in Paragraph 1) means_____________.
A.common B.necessary C.easy D.difficult
56.According to the passage, which of the following is NOT the advice the writer gives?
A.Try to study many subjects in a day. B.Try not to study on the weeekends.
C.Plan in advance. D.Try to set a timetable.
57.It could be inferred from the passage that__________.
A.the writer has a part-time job as an assistant when he was at college
B.you need to set a timetable for yourself
C.you should make a personal timetable if you are bad at balancing your time
D.the writer can arrange his time well when he was at college
58.What is the passage mainly about?
A.I had a good time during my college.
B.How to study well at college.
C.Balance time between study and other aspects of your life.
D.How to plan your things in advance. |

Water and its importance to human life are the center of the world’s attention. March 22 is World Water Day, which has the theme “Water and culture ”this year. Ther are more than one billion people in the world who live without safe drinking water. The United Nations hopes to cut this number in half by 2015.
Solving such a big problem seems like an unreal challenge. But everyone, even teenagers, can do something to help. A teenage girl in the U.S. has set an example to others of her age around the world. Rene Haggerty, 13, was awarded the 2004 Gloria Barron Prize for her work of collecting deserted batteries which pollute water.
In 2003, Haggerty went on a field trip to the Great Lakes Science Centre in Ohio. There, she saw an exhibit about how chemicals in old batteries harm the water of Lake Erie. Haggerty learnt that recycling the batteries was an easy solution. “I think everybody can do it, because everyone uses batteries, and it can make a big difference.”With these words, she began to increase awareness in her area.
She talked to her county government and school board. She got permission to start a recycling programme in schools as well as the public libraries, hospitals, and churches. With the help from her family, friends and local waste-management officials, she gathered containers, arranged transportation, and made an educational video.
Over the past two years, she collected four tons of batteries and drew the attention of officials, who were in charge of a battery recycling programme but had made little progress. When asked if she feels like a hero, Haggerty is quite modest. “Not really. Well, maybe for the fish I saved!”
Every year the Gloria Barron Prize honors young Americans aged 8 to 18 who have shown leadership and courage in serving the public and the planet. Each year ten winners receive ＄2,000 each, to help with their education costs or their public service work.
68.According to the passage, how many people probably can’t drink safe drinking water in 2015?
A.About I billion. B.About 2 billion.
C.About 500 million. D.About 5 million.
69.In order to collect used batteries, Rene Haggerty did the following things EXCEPT_______.
A.gather some containers B.arrange the transportation
C.make an educational video D.go on a field trip
70.The best title for this passage should be_______ .
A.A girl awarded the 2004 Gloria Barron Prize
B.A girl acts to clean the world’s water
C.We should protect our environment
D.A girl collecting batteries |
It has always been said that women are not good drivers, because they simply don"t have very good driving ability. On the other hand, most car accidents happen to men; very few happen to women.
From this, we can see that women are much more careful while driving. Another very interesting fact that we should point out is that in the past, women preferred to let their husbands be the only driver in the family rather than have a driving license. Somehow they were prevented from making this step in their lives, but nowadays there are many women that want to pass their driving tests from an early age.
However, we have to admit that men are more skillful drivers than women, but this does not mean that a woman cannot become a good driver by accumulating (积累) experience. So more and more teenagers and women around the age of thirty now want to pass their driving tests. While taking their driving lessons, they also have a number of special lessons with their parents or somebody in the family that has a driving license, this is just to improve their driving abilities and help them to pass the tests more easily.
To conclude, we can say that women are not such bad drivers. They just need more experience than men in order to be able to drive well. And on the other hand, there are a number of women that show better driving skills than the men around them.
67. Compared with the past, nowadays many women___.
A. prefer to have a driving license
B. have more accidents while driving
C. are somehow prevented from driving
D. are the only driver in the family
68. What advantage do women have over men in driving?
A. They have more skills.
B. They are much more careful
C. They know more traffic rules
D. They have more driving experience
69. What can we infer from the passage?
A. Teenage girls cannot take driving tests.
B. Men didn"t allow women to drive in the past.
C. With enough experience, women can become good drivers.
D. Women can easily pass their tests by taking driving lessons.
70. The passage mainly talks about___.
A. women and their driving ability.
B. men and their driving ability.
C. why men are better drivers than women.
D. why more women like to have a driving license |
If you are afraid of the dark，it’s not a big deal．It’s perfectly normal to feel afraid After all，animals do too. “Fear matters，”says Karen Warkentin，an ecologist．“It’s a good thing，” she adds, “because fear makes you do things that keep you alive.”
Like kids，many animals experience fear and they respond to the feeling in variety of ways．A
frightened turtle pulls its head and legs inside its shell．A small fish will swim away when a big，hungry fish approaches．
Some animals respond to fear in ways you might not expect．The first example is that the fear of being eaten can scare some frogs right out of their eggs. Warkentin made the surprising discovery while studying red—eyed tree frogs in Costa Rica.
In this species，female frogs attach jellylike clumps（果冻一样的块状物）of their eggs to the undersides of leaves．The leaves hang on branches that dangle（悬挂）over ponds．After they hatch from the eggs，the tadpoles（蝌蚪）then fall into the water，where they eventually grow into
adult frogs.
Tree frog eggs usually grow for 6 days before hatching．If they sense that a hungry snake is about to attack，however，they can hatch up to 2 days ahead of schedule. As the snakes are unable to swim，by falling into the water early，the tadpoles can escape.
If hatching early helps protect red—eyed tree frogs from snakes，you might wonder why their eggs don’t always hatch sooner．It turns out that hatching early brings its own danger．Once tadpoles land in the water，hungry fish and other animals like to eat them too．Staying in their eggs for a full 6 days，then，allows frog embryos（胚胎）to grow big and strong．This extra growth improves their chances of surviving in the water．
68．It can be inferred from the passage that fears______
A．help animals grow bigger and stronger
B．are less common among young animals
C．help animals move a lot to fit the environment
D．are more or less important in order for animals to survive
69．We are told in the passage that tree frogs______
A．face danger both inside their eggs and in the water
B．will grow fast if they fall into the water later
C．are surprisingly clever when inside their eggs
D．stay in their eggs longer if they are frightened
70．What do you think would be discussed in the following paragraph?
A．Further explanations as to why tree frogs hatch ahead of schedule．
B．How the unborn frogs know when a snake is about to attack them．
C．Another example of animals that responds to fear in an unexpected way．
D．How tree frogs improve their chances of survival before falling into the water. |
