Researchers in Britain are driving the environmental movement to a new level. A team from the University of Warwick has built what it calls the world’s first completely environmentally friendly Formula Three racing car.
The car is made mainly of renewable materials, like plants and vegetables. The structure around the car is made from natural plant fibers and potatoes. The steering wheel(方向盤(pán)) is made from root vegetables like carrots. The engine uses bio-fuel made from vegetable oil and waste chocolate.
The new racing car is extremely fast. The car has a top speed of two hundred fifteen kilometers an hour. And it can go from zero to ninety-five kilometers an hour in just two and a half seconds. The racing car meets all of the Formula Three racing requirements except for its biodiesel(生物柴油) engine.
Automobile racing is one of the most widely watched sports in the world. But it is also considered one of the least friendly sports to the environment. Racing cars burn a lot of fuel, and create a lot of air pollution. In recent years, the racing industry has taken steps to protect the environment. More racing companies are now producing cars that use less energy. These cars produce less pollution than cars that depend on traditional fuel, like gasoline.
Last month, the new racing car was set to run in its first competitive race at the Formula Three Championship Final at Brands Hatch. It would have been the first biodiesel-powered car to race at Formula Three. Current Formula Three rules let only gasoline-powered car to compete. Officials needed permission from all of the Formula Three racers for the biodiesel-powered car to compete. They were unable to contact one of the drivers, so the new racing car didn’t appear in the event. In test runs, the new racing car was the fifth fastest among the Formula Three race cars. Supporters are hoping to have the fuel problem solved in time to compete in the next season.
小題1:. What’s the second paragraph mainly about?
A．What materials the new racing car is made of.
B．Why researchers built the new racing car.
C．The characteristics of the new racing car.
D．The process of the new racing car being designed.
小題2:.According to the passage, the _________ of the new racing car doesn’t meet the Formula Three racing
requirements.
A．speedB．a(chǎn)ppearanceC．weightD．engine
小題3:. It can be inferred from the passage that __________.
A．the new racing car is the first environmentally friendly car
B．a(chǎn)utomobile racing could be forbidden in the near future
C．many people like to watch automobile racing
D．the new racing car will be allowed to compete in the next season of Formula Three racing
小題4:. In recent years, racing companies are producing cars that __________.
A．burn more fuelB．go more quickly
C．produce less pollutionD．cost less money
小題5:.Why didn’t the new racing car compete at the Formula Three Championship Final last month?
A．Because the new racing car still needs testing.
B．Because officials needed each racer’s permission but failed to contact one.
C．Because there’re some technical problems to be solved.
D．Because few drivers think it is fast enough.

[1]Global difference in intelligence is a sensitive topic, long filled with a large number of different opinions. But recent data has indeed shown cognitive (認(rèn)知的) ability to be higher in some countries than in others. What's more, IQ scores have risen as nations develop—a phenomenon known as the "Flynn effect". Many causes have been put forward for both the intelligence difference and the Flynn effect, including education, income, and even non-agricultural labor. Now, a new study from researchers at the University of New Mexico offers another interesting theory: intelligence may be linked to infectious-disease rates.
　　[2]The brain, say author Christopher Eppig and his colleagues, is the "most costly organ in the human body". Brainpower consumes almost up to 90 percent of a newborn's energy. It's clear that if something affects energy intake while the brain is growing, the impact could be long and serious. And for vast parts of the globe, the biggest threat to a child's body—and therefore brain—is parasitic (由寄生蟲(chóng)引起的) infection. These illnesses threaten brain development________________. They can directly attack live tissue, which the body must then try every means to replace. They can invade the digestive pipe and block nutritional intake. They can rob the body's cells for their own reproduction. And then there's the energy channeled (輸送) to the immune system to fight the infection.
　　[3]Using data on national "disease burdens" (life years lost due to infectious diseases) and average intelligence scores, the authors found they are closely associated. The countries with the lowest average IQ scores have the highest disease burdens without exception. On the contrary, nations with low disease burdens top the IQ list.
　　[4]If the study holds water, it could be revolutionary for our understanding of the still-confusing variation in national intelligence scores.

Howling is a behavior commonly observed among a wolf nark. An animals, wolves work together to hunt and rely on howling was an important means of communication each other. There are different explants of a wolf’s howl and it appears that there may be more to discover.      One theory is that wolves howl to bend better together. It’s almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together . But this theory may be wrong, explains Fred H. Harington, a professor who studies wolf behavior.     Indeed, there have been tines when wolves have been seen one moment howling in a exhorts, and the next, quarreling anions each other. It appears that usually the lowest-tanking menthes of the pack may actually be “punished” for
Joining in the churs at times. So is howling a way to strcagthen a social boad or just a way to reconfirm status among its members? ——Why do welves howl for sure?
What is cleat, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that woloves may separate from one another at times. When this happens, howling appcars to be an ercellent means of gathering.
Howling, interestingly, is a contagious behaviour. When one wolf starts to howl, very likely others will follow. This is often seen to occat in the morning, as if wolves were doing some sotr of “roll rall”where wolves all howl togeter to howl, very likely others will follow. This is often seen to occar in the morning, as if wolves were doing w some sotr of “roll call”where wolves all howl together to repotr their pteence.

A．Wolves separate from each other after howling.
B．Wolves tend to protect their hunting grounds.
C．Wolves sometimes have quarrels after howling together.

  Drawings of human colonies on other planets often picture the entire community under a glass or plastic bubble. The bubble is intended to create an atmosphere with adequate oxygen and other essential elements. But similar bubble-like structures have also been constructed on earth. One of the most famous, and controversial, is a site in the Arizona desert.
Biosphere 2, as it is called, was built not far from Tucson in 1984 and is now run by Columbia University. This huge（7,200,000-cubic-foot）glass and steel construction contains several separate ecosystems, including a desert, a rain forest, and a 900,000-gallon “ocean.” The climatic conditions-humidity, temperature, air quality-are regulated by sensors and can be adjusted as needed or desired. For example, a rainstorm can be created to increase the humidity. The adjustable features of Biosphere 2 make it an ideal location to perform experiments to help determine the effects of such climatic changes as global warming.
The current conditions at Biosphere 2 are vastly different from those in 1993, when eight people who had moved into the environment with great fanfare two years earlier moved out in failure. Though promising to be self-sufficient（自足的）, these “colonists” had so much trouble regulating the environment that they reportedly had food smuggled into them. Oxygen levels became dangerously low; most plants and animals died. In taking over the unsuccessful site, Columbia hopes to erase its notorious past by focusing on small research projects that gradually answer some of Biosphere 1’s — that is, Earth’s most basic environment questions.
小題1:This passage primarily deals with _________.
A．conditions of life in Biosphere 2
B．building controlled environments on other planets
C．why Biosphere 2 failed in the past
D．what makes a good biosphere colonist
小題2:Biosphere 2 is now run by _________.
A．a(chǎn) group of eight colonists
B．Columbia University
C．the city of Tucson
D．scientists who hope to establish Biosphere 3
小題3:The passage suggests that earlier colonists of Biosphere 2 _________.
A．did not like living in a controlled environment
B．found it very difficult to live in a controlled environment
C．still are involved with Biosphere 2
D．have now left the country in disgrace
小題4:The writer helps you understand what Biosphere 2 is like by _________.
A．comparing its features with those of an outer space biosphere
B．explaining the process by which it was constructed
C．referring to an interview with one of former inhabitants
D．describing its appearance and conditions
小題5:In paragraph 3 the word “notorious” means _________.

Who’s in control of your life? Who’s pulling your strings? For the majority of us，it’s other people—society，colleagues，friends，family or our religious community．We learned this way of operating when we were very young，of course．We were brainwashed．We discovered that feeling important and feeling accepted was a nice experience and so we learned to do everything we could to make other people like us．As Oscar Wilde puts it，“Most people are other people．Their thoughts are someone else’s opinions，their lives a mimicry，their passions a quotation．”
So when people tell us how wonderful we are，it makes us feel good．We long for this good feeling like a drug—we are addicted to it and seek it out wherever we can．Therefore，we are so eager for the approval(贊同)of others that we live unhappy and limited lives，failing to do the things we really want to．Just as drug addicts and alcoholics live worsened lives to keep getting their fix(一劑毒品)，we worsen our own existence to get our own constant fix of approval．
But，just as with any drug，there is a price to pay．The price of the approval drug is freedom—the freedom to be ourselves. The truth is that we cannot control what other people think．People have their own agenda，and they come with their own baggage and，in the end，they’re more
interested in themselves than in you．Furthermore，if we try to live by the opinions of others，we will build our life on sinking sand．Everyone has a different way of thinking，and people change
their opinions all the time．The person who tries to please everyone will only end up getting exhausted and probably pleasing no one in the process．
So how can we take back control? I think there’s only one way—make a conscious decision to stop caring what other people think．We should guide ourselves by means of a set of values—not values imposed from the outside by others，but innate values which come from within．If we are driven by these values and not by the changing opinions and value systems of others，we will live a more authentic，effective，purposeful and happy life．
小題1:．What Oscar Wilde says implies that        ．
A．we have thoughts similar to those of others
B．most people have a variety of thoughts
C．other people’s thoughts are more important
D．most people’s thoughts are controlled by others
小題2:．What does the author try to argue in the third paragraph?
A．Changing opinions may cost us our freedom．
B．We may lose ourselves to please others．
C．We need to pay for what we want to get．
D．The price of taking the drug is freedom．
小題3:．It can be concluded from the passage that         ．
A． it’s better to do what we like
B．we shouldn’t care what others think
C．we shouldn’t change our own opinions
D．it’s important to accept others’ opinions

It doesn’t matter whether foods are eaten raw or cooked, canned or frozen. It doesn’t matter if a person eats dinner at 4 o’clock in the afternoon or at eleven o’clock at night. The important thing is what you eat every day.
There are two problems, then, in feeding the large number of people on earth. The first thin g is to find some ways to feed the world’s population so that no one is hungry. The second is to make sure that people everywhere have the right kind of food to make them grow to be strong and healthy.

A person steps on what seems like solid ground but discovers with horror that the ground is giving way underfoot. The person struggles desperately but is trapped. There is no escape. Slowly the person sinks deeper and at last is gone. The solid ground was solid only in appearance. It was actually quicksand, which is a deep mass of fine sand mixed with water.
How is quicksand formed? Water pushes up from below the surface and is held by the sand. The grains of sand are forced apart by the water. They cannot hold any weight. The subsurface water may have come from a spring, a river, or a stream. Sometimes pools of water near beaches become filled with sand. When the soil under these pools does not allow for good drainage(排水), the sand can become stretches of quicksand.
Is it true that a person who steps into quicksand is doomed to die? No, for people have fought their way from quicksand to firm land again. It is panic(恐慌) that creates the condition that can result in death, for the more a person struggles, the worse matters become. Quick movements will make the sand yield for a time, but then it rushes back and settles solidly around the body.
People trapped in quicksand should either lie back with arms outstretched, or not move at all. When the weight of the sand around his body has displaced equals that person’s weight, the victim will stop sinking. With feet held still, and with slow movements of the arms, as in the backstroke(仰泳) in swimming, people have managed to roll to safety and reach firm ground.
小題1:Quick movements by a person trapped in quicksand will _______.
A．help the person reach firm ground
B．help prevent panic
C．make the same sand yield temporarily
D．make the sand hold the person’s weight
小題2:Quicksand is _______.
A．a(chǎn) mass of fine sand mixed with waterB．formed only along rivers
C．found below subsurface waterD．solid ground
小題3:Which statement does the article lead you to believe?
A．Stretches of quicksand are found only under the sea.
B．People should never try to escape from quicksand.
C．It is hard to keep calm if you fall into quicksand.
D．Only heavy people can be trapped in quicksand.
小題4:The passage mainly tells about _______.
A．what solid ground looks likeB．the nature of quicksand
C．stepping into quicksandD．escaping from quicksand

You know that pearls grow inside oysters(牡蠣), but would you ever think to look for diamonds inside an ostrich(鴕鳥(niǎo))? Well, a hunter once shot an ostrich and discovered, to his great surprise, that the big bird had swallowed a bunch of diamonds. How could such a strange thing happen?
Like many other birds, the ostrich swallows small stones that stay inside its “gizzard”. The gizzard is a bird’s second stomach. It is where the food is ground up. The small stones help to grind up the food so it can be digested. The small stones do the chewing because birds don’t have teeth. In that case of the ostrich with the diamonds, the bird simply had expensive taste in rocks. It used the diamonds to digest its dinner.
Diamonds and stones aren’t all that an ostrich will swallow. If there are no stones around, it will eat just about anything. Sadly for ostriches in zoos, this can be a fatal habit. The tendency to swallow anything it sees has caused the death of many an ostrich. Cruel or careless people often throw things into the bird’s living space. They throw keys, coins, and even large objects such as horseshoes. The ostrich swallows them without hesitation. Coins can be the worst. Inside the ostrich they wear down to a razor-sharp edge. They will cut open the bird’s gizzard from the inside. When one young zoo ostrich died, 484 coins weighing more than eight pounds were found in its gizzard.
小題1:
Which of the following best expresses the main idea of the passage?
A．Birds often eat strange and funny things.
B．Ostriches will swallow anything to help them digest food.
C．One ostrich died with 484 coins in its gizzard.
D．Ostriches are often hurt by cruel or careless people.
小題2:
The ostrich is not smart enough to ______.
A．digest its own foodB．eat only diamonds
C．a(chǎn)void eating harmful objectsD．escape from the zoo
小題3:
The sentence “the small stones do the chewing” makes rocks seem as though they were ______.
A．importantB．a(chǎn)live
C．dangerousD．uncomfortable

The hole in the Earth’s ozone layer(臭氧層) has until now protected Antarctic from the worst effects of global warming, but scientists have warned that as the hole closes up in the next few decades, temperatures on the continent could rise by around 3℃ on average, with melting ice contributing to a global sea level increase of up to 1.4 meters.
In the past decades the western Antarctic has seen rapid ice loss as the world has warmed, but the other parts of the continent have, paradoxically, been cooling, resulting in a 10% increase in ice in the seas around the region. This is because the hole in the ozone layer has increased cold winds in Antarctic, making much of the continent surface colder than usual.
But now that the gases that cause the ozone hole have been banned, scientists expect the hole to repair itself within the next 50 to 60 years. By then the cooling effect will have faded out and the Antarctic will face the full impact of global warming. This means an increase in average air temperatures of around 3℃ and a reduction in sea ice by around a third.
The biggest threat to the continent comes from warming seas. Robert Johnson, a scientist who monitors Antarctic ice sheets, said, “The ice sheets in Antarctic are hundreds of meters thick. But once warm ocean waters start flowing underneath, the ice will begin thinning and could break up very quickly.” Thinning ice sheets cause ice to break away from the continent and to melt even faster. Escaping ice from western Antarctic has already resulted in a 10% rise in global sea level in recent decades.
Johnson believes that international action to reduce global warming is required immediately or it may be too late. “Everything is connected——Antarctic may be a long way away but it is an important part of the Earth’s system,” said Johnson. “It contains 90% of the world’s ice, 70% of the world’s fresh water and that is enough, if it melts completely, to raise sea levels by 63 meters.”
Even in a worse-case situation scientists don’t expect the ice to entirely disappear, but predict that, because of the melting ice sheets, average sea level rise will be around 1.4 meters higher by the end of the century.
小題1:
The underlined word “paradoxically” (in paragraph 2) most probably means “     ”.
A．rapidlyB．generallyC．contradictorilyD．a(chǎn)pparently
小題2:
What is the effect of the hole in the ozone layer on Antarctic?
A．It is causing the ice to melt faster.
B．It is making much of the continent colder.
C．It is making the effects of global warming in the region worse.
D．It is reducing the amount of water in Antarctic.
小題3:
What do scientists think is the biggest danger facing Antarctic?
A．Rising sea levels.B．Warming sea water temperature.
C．Water pollution.D．Growing ice sheets.
小題4:
Which of the following is true according to the passage?
A．Antarctic is currently experiencing the full effects of global warming.
B．The average temperature has increased by 3℃ in recent decades.
C．Antarctic contains most of the world’s fresh water.
D．Ten percent of Antarctic’s ice has already been lost.
