With alarming regularity,we read about oil tankers having accidents near land and the terrible consequences of the oil spills(泄露) on people,nature,and the environment.
Millions of dollars have been used in developing special chemicals to help dismiss the spills and to clean up the animals,beaches,and land spoiled by the oil.Unfortunately,when many of these chemicals are used,,more damage is caused to the environment,especially to lives in the sea.
Of all of today’s environmental disasters ,an oil spill may actually be one of the least serious.Although oil is poisonous,it is a natual material.In the end,it breaks down naturally.There are,of course,long-term effects,but it is usually more serious in the short term.
Nature by itself woks better than chemical materials,but when there is a spill we demand that governments act immediately with as much hi-tech knowledge as possible.In 1967 the tanker Torrey Canyon sank off the Scilly Isles near the coast of England and spilled 120,000 tones of oil into the ocean,If you go there today,you will find it hard to see any sign that it ever happened.
Governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental
damage.Interestingly the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run I
We shoule be thinking more about reducing our dependency on oil,Governments should be encouraging research into new technologies，such as cars run by solar power（太阳能），electricity,
hydrogen，and so on.Much of this research has ,in the past been held back by the oil,gas,and coal.
If the world’s millions of cars were 10% more efficient（高效的）—and the industry could easily produce cars at least twice as efficient？we would need many fewer tankers crossing the oceans each year.If this happened,the risks of oil spills would be reduced，and the air we breathe would be cleaner and fresher ,too.

The majority of astronauts（宇航员）from America have been men．At the start of the space programme there was strong resistance from some people against having women in space．However, some women were very keen to become astronauts and in the end they were successful．In 1978, NASA began the first training programme for women astronauts．
Judy Resnick and Christa McAuliffe were both astronauts and they were both women, but in many other ways they were very different．Both of them were on Flight STS-5L-L．Judy Resnick was born in 1949 and studied engineering at university and went on to obtain a PhD in 1977．She was a member of the first group of women selected for astronaut training in 1978, and in 1984, she became the second woman in space．During that flight, she helped to launch three new satellites and she carried out a programme of research．She was, in many ways, a professional astronaut whose whole life was devoted to space travel．
Christa McAuliffe was born in 1948 and she was an astronaut almost by accident．In 1984, NASA decided to find a teacher who could accompany astronauts into space．They hoped that she would be able to communicate with students from space and encourage every one of them to be interested in space travel．Christa was a secondary teacher in history and social studies．She was a gifted teacher and she was selected from over 11,000 applicants to go on flight STS-51-L．She was also a very good communicator and she immediately established a very good relationship with the news media(radio, television and newspapers）．It was partly because of this that there was a great deal of interest and excitement about the flight．Thousands of students in schools and universities all around the country were looking forward to communicating with Christa in space．Millions of people were watching her flight with great interest．It is partly because of the excitement over McAuliffe's place in the flight that the disaster in 1986 had such an effect on people．We can learn from the first two paragraphs that ___________．
| A．Judy was against the idea of having women in space at first |
| B．Judy was the first woman selected for astronaut training |
| C．Judy helped to launch three new satellites at the age of 35 |

A recent study of ancient and modern elephants has come up with the unexpected conclusion that the African elephant is divided into two distinct (不同的) species
The discovery was made by researchers at York and Harvard universities when they were examining the genetic relationship between the ancient woolly mammoth and mastodon to modern elephants—the Asian elephant, African forest elephant and African savanna elephant
Once they obtained DNA sequences (序列) from two fossils (化石)，mammoths and mastodons the team compared them with DNA from modern elephants. They found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian elephants and mammoths.
The scientists used detailed genetic analysis to prove that the African savanna elephants and the African forest elephants have been distinct species for several million years. The divergence of the two species took place around the time of the divergence of Asian elephants and woolly mammoths. This result amazed all the scientists.
There has long been debate in the scientific community that the two might be separate species but this is the most convincing scientific evidence so far that they are indeed different species.
Previously, many naturalists believed that African savanna elephants and African forest elephants were two populations of the same species despite the elephants’ significant size differences. The savanna elephant has an average shoulder height of 3.5metres while the forest elephant has an average shoulder height of 2.5metres. The savanna elephant weighs between six and seven tons, roughly double the weight of the forest elephant. But the fact that they look so different does not necessarily mean they are different species. However, the proof lay in the analysis of the DNA.
Alfred Roca, assistant professor in the department of Animal Sciences at the University of Minois, said, “We now have to treat the forest and savanna elephants as two different units for conservation purpose. Since 1950 all African elephants have been conserved as one species. Now that we know the forest and savanna elephants are two very distinct animals, the forest elephant should become a bigger priority (优先)for conservation purpose .”One of the fossils studied by the researchers is that of ________.
| A．the Asian elephant | B．the forest elephant |
| C．the savanna elephant | D．the mastodon elephant |
The underlined word “divergence” in paragraph 4means “________”
| A．evolution | B．exhibition | C．separation | D．examination |
The researcher’s conclusion was based on a study of the African elephant’s ____________
| A．DNA | B．height | C．weight | D．population |
What were Alfred Roca’s words mainly about?
| A．The conversation of African elephants. |
| B．The purpose of studying African elephants |
| C．The way to divide African elephants into two units |
| D．The reason for the distinction of African elephants |
Which of the following can be the best title for the passage?
| A．Naturalist’s Belief about Elephants. |
| B．Amazing Experiment about Elephants |

To err is human. To blame the other guy is even more human.
Common sense is not all that common.
Why tell the truth when you can come up with a good excuse?
These three popular misquotes（戏谑的引语）are meant to be jokes, and yet they tell us a lot about human nature. To err, or to make mistakes, is indeed a part of being human, but it seems that most people don’t want to accept the responsibility for having made a mistake. They naturally look for someone else who could be responsible for the problem. Perhaps it is the natural thing to do. The original quote about human nature went like this：“To err is human, to forgive, divine（神圣的）.” This saying mirrors an ideal：people should be forgiving of others’ mistakes. Instead, we tend to do the opposite—find someone else to pass the blame on to. However, taking responsibility for something that went wrong is a mark of great maturity.
Common sense is what we call clear thought. Having common sense means having a good general plan that will make things work well, and it also means staying with the plan. Common sense tells you that you take an umbrella out into a rainstorm, but you leave the umbrella home when you hear a weather forecast for sunshine. Common sense does not seem to be common for large organizations, because there are so many things going on that one person cannot be in charge of everything . People say that in a large company, “the right hand does not know what the left hand is doing.”
And what is wrong with a society that thinks that making up a good excuse is like creating a work of art? One of the common problems with making excuses is that people, especially young people, get the idea that it’s okay not to be totally honest all the time. There is a corollary（直接推论）to that：if a good excuse is “good” even if it isn’t honest, then where is the place of the truth?According to the passage, which of following seems the most human?
| A．To search for truth. |
| B．To achieve one’s ideal. |
| C．To make fun of others’ mistakes． |
| D．To criticize others for one’s own error. |
Which of the following is NOT based on common sense?
| A．A man tries to take charge of everything in a large company. |
| B．A student goes out with an umbrella in stormy weather. |
| C．A company’s next move follows a good plan. |
| D．A lawyer acts on fine judgments. |
What is the author’s opinion about a good excuse?
| A．Making a good excuse is sometimes a better policy. |
| B．Inventing a good excuse needs creative ideas. |
| C．A good excuse is as rewarding as honesty. |
| D．Bitter truth is better than a good excuse. |
What would be the best title for his passage?
| A．A Mirror of Human Nature |
| B．To Blame or to Forgive |
| C．A Mark of Maturity |
| D．Truth or Excuse |

One evening in February 2007, a student named Paula Ceely brought her car to a stop on a remote road in Wales. She got out to open a metal gate that blocked her path. That’s when she heard the whistle sounded by the driver of a train. Her Renault Clio was parked across a railway line. Seconds later, she watched the train drag her car almost a kilometer down the railway tracks.
Ceely’s near miss made the news because she blamed it on the GPS. She had never driven the route before. It was dark and raining heavily. Ceely was relying on her GPS, but it made no mention of the crossing. “I put my complete trust in the device（设备）and it led me right into the path of a speeding train,” she told the BBC.
Who is to blame here? Rick Stevenson, who tells Ceely’s story in his book When Machines Fail Us, points the finger at the limitations of technology. We put our faith in digital（数码）devices, he says, but our digital helpers are too often not up to the job. They are filled with small problems. And it’s not just GPS devices：Stevenson takes us on a tour of digital disasters involving everything from mobile phones to wireless keyboards.
The problem with his argument in the book is that it’s not clear why he only focuses on digital technology, while there may be a number of other possible causes. A map-maker might have left the crossing off a paper map. Maybe we should blame Ceely for not paying attention. Perhaps the railway authorities are at fault for poor signaling system. Or maybe someone has studied the relative dangers and worked out that there really is something specific wrong with the GPS equipment. But Stevenson doesn’t say.
It’s a problem that runs through the book. In a section on cars, Stevenson gives an account of the advanced techniques that criminals use to defeat computer-based locking systems for cars. He offers two independent sets of figures on car theft; both show a small rise in some parts of the country. He says that once again not all new locks have proved reliable. Perhaps, but maybe it’s also due to the shortage of policemen on the streets. Or changing social circumstances. Or some combination of these factors.
The game between humans and their smart devices is amusing and complex. It is shaped by economics and psychology and the cultures we live in. Somewhere in the mix of those forces there may be a way for a wiser use of technology.
If there is such a way, it should involve more than just an awareness of the shortcomings of our machines. After all, we have lived with them for thousands of years. They have probably been fooling us for just as long.The phrase “near miss” (Paragraph 2) can best be replaced by______.
| A．close hit | B．heavy loss | C．narrow escape | D．big mistake |
Which of the following would Rick Stevenson most probably agree with?
| A．Modern technology is what we can’t live without. |
| B．Digital technology often falls short of our expectation. |
| C．Digital devices are more reliable than they used to be. |
| D．GPS error is not the only cause for Ceely’s accident. |
In the writer’s opinion, Stevenson’s argument is _______.
| A．one-sided | B．reasonable | C．puzzling | D．well-based |
What is the real concern of the writer of this article?
| A．The major causes of traffic accidents and car thefts. |
| B．The relationship between human and technology. |
| C．The shortcomings of digital devices we use. |
| D．The human unawareness of technical problems. |
