Scientists say they have discovered a promising treatment for sleeping sickness, a killer disease that infects(感染) about 60,000 people in Africa a year．
British and Canadian experts say drugs could attack the parasite（寄生虫） causing the illness．They say the drug could be ready for human medical test in about 18 months．
The disease, spread by the bite of a fly, is caused by a parasite attacking the central nervous system．It has similar symptoms（症状） to malaria（疟疾）, making it difficult to diagnose．Left untreated, it moves to the brain, resulting in mental confusion and final death
The "breakthrough" came at the University of Dundee in Scotland, where scientists were offered money to research diseases ignored by major drugs companies．
Professor Paul Wyatt, director of the programme, said: "This is one of the most significant findings made in recent years in terms of drug discovery and development for ignored diseases."
He said the research, published in the journal Nature, represented "significant progress" in the development of a full blown drug against the disease．
The World Health Organization said there are between 50,000 and 70,000 cases of the disease a year, with a further 60 million people at risk of infection．
The research in Dundee was backed by partners at the University of York in England and the Structural Genomics Consortium in Toronto, Canada．The two drugs currently available to treat sleeping sickness both have problems．One is with side effects that kill one in 20 patients and the other is costly, only partially effective and requires long-time hospital treatment, the scientists said．The word backedin the last paragraph probably means_____.
| A．conducted | B．supported | C．believed | D．managed |
What the World Health Organization said suggested that______.
| A．about 60000 people died of the disease each year |
| B．about 60000 people were cured of the disease each year |
| C．600 million people are likely to get infected |
| D．the disease is spreading fast in Africa |
We can read this passage______.
| A．in the journal Nature |
| B．in a newspaper of the University of Dundee |
| C．in a book about flies |
| D．in a newspaper about medicine |
We can learn from the passage that______．
| A．big drug companies play an important role in the research of the new drug |
| B．people who get infected with the disease are mentally disturbed |
| C．among 200 people infected with the disease, 5 may die because of the old drug |
| D．Professor Paul Wyatt may be a professor at the University of York |
In his 1930 essay "Economic Possibilities for Our Grandchildren ", John Keynes, a famous economist, wrote that human needs fall into two classes: absolute needs ,which are independent of what others have , and relative needs ,which make us feel superior to our fellows. He thought that although relative needs may indeed be insatiable (无止境的) , this is not true of absolute needs.
Keynes was surely correct that only a small part of total spending is decided by the desire for superiority. He was greatly mistaken, however, in seeing this desire as the only source of insatiable demands.
Decisions to spend are also driven by ideas of quality which can influence the demands for almost all goods, including even basic goods like food. When a couple goes out for an anniversary dinner, for example, the thought of feeling superior to others probably never comes to them. Their goal is to share a special meal that stands out from other meals.
There are no obvious limits to the escalation of demand for quality. For example, Porsche, a famous car producer, has a model which was considered perhaps the best sport car on the market Priced at over $120,000, it handles perfectly well and has great speed acceleration. But in 2004, the producer introduced some changes which made the model slightly better in handling and acceleration. People who really care about cars find these small improvements exciting. To get them, however, they must pay almost four times the price.
By placing the desire to be superior to others at the heart of his description of insatiable demands, Keynes actually reduced such demands. However, the desire for higher quality has no natural limits.

To take the apple as a forbidden fruit is the most unlikely story the Christians（基督教徒）ever cooked up. For them, the forbidden fruit from Eden is evil（邪恶的）. So when Columbus brought the tomato back from South America, a land mistakenly considered to be Eden, everyone jumped to be the obvious conclusion. Wrongly taken as the apple of Eden, the tomato was shut out of the door of Europeans.
What made it particularly terrifying was its similarity to the mandrake, a plant that was thought to have come from Hell（地狱）.What earned the plant its awful reputation was its roots which looked like a dried-up human body occupied by evil spirits. Tough the tomato and the mandrake were quite different except that both had bright red or yellow fruit, the general population considered them one and the same, too terrible to touch.
Cautious Europeans long ignored the tomato, and until the early 1700s most of the Western people continued to drag their feet. In the 1880s, the daughter of a well-known plant expert wrote that the most interesting part of an afternoon tea at her father’s house had been the “introduction of this wonderful new fruit—or is it a vegetable?” As late as the twentieth century some writers still classed tomatoes with mandrakes as an “evil fruit”.
But in the end tomatoes carried the day. The hero of the tomato was an American named Robert Johnson, and when he was publicly going to eat the tomato in 1820, people journeyed for hundreds of miles to watch him drop dead. “What are you afraid of?” he shouted. “I’ll show you fools that these things are good to eat!” Then he bit into the tomato. Some people fainted. But he survived and, according to a local story, set up a tomato-canning factory.The tomato was shut out of the door of early Europeans mainly because ______.
| A．it made Christians evil. |
| B．it was the apple of Eden |
| C．it came from a forbidden land |
| D．it was religiously unacceptable |
What can we infer the underlined part in Paragraph 3 ?
| A．The process of ignoring the tomato slowed down |
| B．There was little progress in the study of the tomato |
| C．The tomato was still refused in most western countries |
| D．Most western people continued to get rid of the tomato |
What is the main reason for Robert Johnson to eat the tomato publicly?

| C．To speed up the popularity of the tomato |
| D．To persuade people to buy products from his factory |
What is the main purpose of the passage ?
| A．To challenge people’s fixed concepts of the tomato |

There is no better way to enjoy Scottish traditions than going fishing and tasting a little bit of whisky(威士忌)at a quiet place like the Inverlochy Castle. When Queen Victoria visited the castle in 1873, she wrote in her diary, “I never saw a lovelier spot ,” And she didn’t even go fishing.
Scotland is not easily defined. In certain moments, this quiet land of lakes and grasses and mountains changes before your very eyes. When evening gently sweeps the hillside into orange light, the rivers, teeming with fish, can turn into streams of gold . As you settle down with just a fishing pole and a basket on the bank of River Orchy, near the Inverlochy Castle , any frustration(烦恼) will float away as gently as the circling water. It’s just you and purple, pink, white flowers, seeking a perfect harmony. If you are a new comer to fishing, learning the basics from a fishing guide may leave you with a lifetime’s fun. For many, fishing is more than a sport; it is an art.
Scotland offers interesting place where you can rest after a long day’s fishing. Set against a wild mountain and hidden behind woodland, the beautiful Inverlochy Castle Hotel below the Nevis is a perfect place to see the beauty of Scotland’s mountains. Ben Nevis is the highest of all British mountains, and reaching its 1343-metre top is a challenge. But it’s not just what goes up matters; what comes down is unique. More than 900 metres high, on the mountain’s north face, lies an all-important source of pure water. Its name comes from the Gaelic language “usquebaugh” or “water of life”; and it is the single most important ingredient(原料) in Scotland’s best known drink: whisky.The story of Queen Victoria is to show that _____.
| A．the queen is rich in tour experience |
| B．the Castle is a good place to go in Scotland |
| C．tasting whisky is better than going fishing |
| D．1873 is a special year for the queen |

| C．By analyzing causes. | D．By making comparisons. |
What is Ben Nevis special for?
| A．The Inverlochy Castle Hotel . |
| B．The beauty of its surroundings. |
| C．The water from the mountain. |
| D．The challenge up to its top. |

Top lists are lecturing people on everything from “100 places to visit” to “100 books to read ”.
Aren't you just tired of being told what to do with your time?
Now you have a list to end all lists!
Take a look at the following two examples from the list of “101 things not to do”:
Swim with Dolphins（海豚）？
Swimming with dolphins is one of the world’s most profitable tourist activities. However, every dolphin will welcome having their busy, tiring day interrupted by tourists screaming and pushing around them in the water. Worse yet, when dolphins get too near to the boats loaded with tourists, they could get caught up in ropes and killed by propellers(螺旋桨).
Here’s a little secret. Dolphins look like smiling at you, but actually they’re just opening their mouths.
Go to See the Mona Lisa?
There must be something about the mysterious(神秘的)smile. The 6 million people who visit the lady in the Louvre every year can’t all be wrong, after all. But they can be quite annoying, standing in front of you, holding up their cameras to prevent you from seeing anything. In fact, it is hard for you to see the painting clearly because you have to stay away from it for security reasons. After queuing for hours, many tourists can remain in front of the painting only for 15 seconds at most.
If the mysterious lady in the picture knew her fate, she wouldn’t just be smiling, she’d be laughing.
