After years of hearing drivers complain about scratches (划痕) on their cars, Japan’s Nissan Motor Company has officially announced the next big thing--a paint that not only resists scratches and scrapes, but actually repairs itself within a few days.
The new material, developed by Nippon Paint Company, contains an elastic rubbery-like resin (弹性树脂) that is able to heal minor (较小的) marks caused by car wash equipment, parking lot encounters, road debris (石头碎片) or even on-purpose destruction.
The automaker admits its results vary depending on the temperature and the depth of the damage, but adds this is the only paint like it in the world, and tests prove it works.
Minor scratches, the most common type, are said to slowly fade over about a week. And once they’re gone, there is no trace (痕迹) that they were ever there.
The special paint is said to last for at least three years after it is first applied, but there is no word yet on whether more can be added after that period.
Nissan claims car washes are the worst offenders for this type of damage, accounting for at least 80 percent of all incidents.
But the complete auto-healing won’t come without scratching your wallet. The vehicle maker notes the special paint adds about $ 100 US to the price of a car.
It plans to use its new chemical mixture only on its X-Trail SUVs in Japan for now, as it looks for a more widespread presentation. And while plans to offer the feature overseas haven’t been made yet, if it’s a hit there, you can be almost sure market forces will drive it to these shores, as well.

If you go into the forest with friends, stay with them always. If you don’t, you may get lost. If you really get lost, this is what you should do. Sit down and stay where you are. Don’t try to find your friends—let them find you by staying in one place.
There is another way to help your friends or other nearby people to find you. Give them a signal by shouting or whistling (打口哨) three times. Stop. Then shout or whistle three times. Any signal given three times is a call for help.
Keep up the shouting or whistling always three times together. When people hear you, they will know that you are not just making noise for fun. They will let you know that they have heard your signal. They will give two shouts, two whistles or two gun shots (枪声). When someone gives a signal, it is an answer to a call for help.
If you don’t think that you will get help before 
night comes, try to make a little house—cover up the holes with branches (树枝) with lots of leaves. Make yourself a soft bed with leaves and grass.
What should you do if you get hungry or need drinking water? You would have to leave your little branch house to look for a river. Don’t just walk away. Pick off small branches and drop them as you walk so that you can find your way
back.
The most important thing to do when you are lost is—stay in one place. If you get lost in the forest, you should__________.
| A．stay where you are and give a signal |
| B．walk around the forest and shout so that your friends might hear you |
| C．try to find your friends as soon as possible |
D．try to get out of the for est and shout for help |
Which signal is a call for help?
| A．Shouting here and there. |
| B．Crying twice. |
| C．Shouting or whistling three times together. |
| D．Whistling everywhere in the forest. |
Which of the following is true according to the passage?
| A．When you hear two shouts or whistles, you know that people will soon come to help you. |
| B．When you can’t get help before night comes, put up a tent in the open air. |

If you ask people to name a person who had the greatest effect on the English language, you will get answers like “Shakespeare” “Samuel Johnson” and “Webster”, but none of these men had any effect at all compared to a man who didn’t even speak English—William the Conqueror.
Before 1066, in the land we now call Great Britain lived people in two main language groups. One was a Celtic language, the other was what we now call Anglo-Saxon (or old English), a Germanic language. If this had lasted, English today would be close to German.
But this didn’t last. In 1066 the Normans led by William began their rule over England. For about a century, French became 
the official language of England while Old English became the language of farmers. As a result, English wor
ds of politics (政治) and the law come from French rather than German. In some cases, modern English even shows a difference between upper-class French and lower-class Old English in its words. We even have different words for some foods, meat in particular, depending on whether it is still out in the fields or at home ready to be cooked.
This shows the fact that the lower-class farmers were doing farming, while the upper-class Normans were doing most of the eating.
When Americans visit Europe for the first time, they usually find Germany more “foreign” than France because the German they see on signs and ads seems much more different from English than French does. Few realize that the English language is actually Germanic in its beginning and that the French influences are all the results of one
man’s ambition (野心).Before 1066, the two main languages spoken in the place wh
ich we now call “Great Britain” were __________.
| A．Germanic and French |
| B．Nordic and Germanic |

Why do Americans find France less foreign than Germany?
| A．Many signs and ads are in English. |
| B．They know little about the history of the English language. |
| C．Many French words are similar to English ones. |
| D．They know French better than German. |
Which of the following is the best title of the passage?
| A．The History of Great Britain. |
| B．The Similarity (相似点) between English and French. |

The Roman Emperor Claudius II was fighting many wars. He wanted a strong army, but many men did not want to be soldiers. Claudius thought the men wanted to stay at home to be with their wives and children instead of leaving to fight wars.
Claudius thought of an awful solution to his problem. He decided to cancel all marriages! No one in all of Rome could get married. Claudius thought that if the men couldn’t get married, the men would ignore the women and want to be soldiers.
Valentine, who was a priest (牧师), believed that people needed to get married. He thought it was wrong for people to live together without being married. So he secretly and illegally married couples anyway. He performed the weddings in secret places, so the Roman soldiers would not find out.
But they did find out. Valentine was arrested and brought before the Emperor. The Emperor thought Valentine was a well-spoken and wise young man, and encouraged him to stop being a Christian (基督徒) and become a loyal Roman. Valentine would not deny his beliefs, and he refused. He was sent to prison and was finally killed. While he was in prison, he sent out letters to his friends and asked to be prayed (祈祷) for by writing Remember your Valentine.
Valentine was killed on the 14th or the 24th of February in the year 269 or 270. We celebrate Valentine’s Day on February 14th in honor of St. Valentine. The Emperor Claudius II wanted men to __________.

Given Australia’s size and the fact that early settlements were far apart, Australian society is remarkably homogeneous (同种的). Its citizens are fundamentally prosperous and the way of life in the major cities and towns is much the same however many miles divide them. It takes a sharp ear to identify regional accents.
However, there is some difference in lifestyle between city dwellers and the country people. Almost 90 per cent of the population lives in the fast-paced cities along the coast and has little more than a passing familiarity with the desert. The major cities preserve pockets of colonial heritage, but the overall impression is modern, with new buildings reflecting the country’s youth. In contrast, the rural communities tend to be slow-moving and conservative. For many years, Australia was said to have “ridden on the sheep’s back”, a reference to wool being the country’s main money earner. However, the wool industry is no longer dominant. Much of Australia’s relatively sound economy is now achieved from natural coal and wheat, and by being the largest diamond producer in the world. Newer industries such as tourism and wine making are also increasingly important. Australians are generally friendly and relaxed, with a self-deprecating sense of humor. On the whole, Australia is a society without hierarchies (等级制度), an attitude generally held to stem from its prisoner beginnings.
Yet, contrary to widespread belief, very few Australians have true prisoner origins. Within only one generation of the arrival of the First Fleet in 1788, Australia had become a nation of immigrants. Originally coming almost entirely from the British Isles, today one in three Australians comes from elsewhere. Australia’s liberal postwar immigration policies led to an influx of survivors from war-torn Europe, most notably Greeks, Italians, Poles and Germans.
The emphasis has shifted in recent years and today the majority of new immigrants are from Southeast Asia. Today Australia is a ‘blend of nations’ and although some racism exists, it has generally been a successful experiment and the country is justifiably proud to have one of the most harmonious multicultural communities in the world.What does the writer mean by saying “It takes a sharp ear to identify regional accents.” in the first paragraph?
| A．Australians speak Standard English with no local accents. |
| B．You have to practice a lot to learn to understand the different accents. |
| C．The Australian regional accents are very difficult to understand indeed. |
| D．There is not much difference between the accents in different areas of Australia. |
Which of the following statements is TRUE according to the passage?
| A．Most Australians have ancestors who were prisoners. |
| B．The Australian economy is dependent on sheep exports. |
| C．The majority of people living in Australia come from Europe. |
| D．The pace of life is different in the city and in the country. |
The underlined pronoun ‘it’ in the final paragraph refers to “_______”.
| A．Community | B．Racism |
| C．Blend of Nations | D．Southeast Asia |
We can infer from the passage that _____.
| A．there are no signs of Australia’s colonial past in its modern cities |
| B．Australia’s recent immigration policy encourages immigrants from Southeast Asia |
| C．immigrants from Southeast Asia have brought racial problems |
| D．“riding on sheep’s back” resulted in slow development in rural communities |
This passage mainly focuses on Australia’s ______.
| A．society | B．economy | C．racial problems | D．history |
The hole in the Earth's ozone layer (臭氧层) has until now protected Antarctica 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°C 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 Antarctica, making much of the continent surface colder than usual.
But now that the gasses 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°C 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 Antarctica ice sheets, said, "The ice sheets in Antarctica are hundreds of metres 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 Antarctica 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 —Antarctica 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. The underlined word "paradoxically" (in Paragraph 2) most probably means "__".
| A．rapidly | B．approximately | C．contradictorily | D．apparently |
What is the effect of the hole in the ozone layer on Antarctica?
| 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 Antarctica. |
