Australian scientists say an organic compound(复合物) used by Indian women to paint dots or bindi on their foreheads could hold the key to a breakthrough in cancer treatment. Rose Bengal was first used in the early 1900s as a dye for food, textiles and cosmetics. But now it is proving to be a useful weapon in the fight against skin cancer.
Television advertisements constantly warn of the dangers of overexposure to the fierce sun. Among them is the possibility of the disease melanoma(黑瘤), a type of skin cancer. More than 1,200 Australians die every year from the disease.
Initial trials of a solution of Rose Bengal injected into some melanoma cells have had a 75 percent success rate in controlling the disease. Professor John Thompson, the director of the Melanoma Unit at the University of Sydney, says this organic dye could become a powerful cancer-fighting treatment.
“We believe it works by getting into the tumor(肿块) cells and causing them to self-destruct. But the exact mechanism by which it works is not totally clear. It’s not useful for people who have a primary melanoma. The treatment of primary melanoma is surgical excision(切除),”he said. “It’s useful to inject tumors for people who have recurrences; when the primary treatment has failed and when recurrence in the area, or at more distant sites has occurred.”
About 90 percent of Australians who develop melanoma survive thanks to early diagnosis and treatment. If left untreated, however, the disease can be fatal.
Convincing younger people in Australia about the dangers of overexposure to the sun is a battle campaigners are constantly waging.
Veronica Manock, a 21-year-old student, had two major operations to remove a cancerous tumor from her leg.
“I’ve had a lot of friends who just said ‘I thought it was just, you know, I’ll get a mole(痣) cut out and that’s it’, whereas I don’t think people realize how much danger they’re putting themselves into and how easy it is to stop something like this happening to you just from doing little things,”said Marock.
Other researchers in Australia are investigating genetic treatments to skin cancer. There is a pressing need for such research to produce effective treatments. Australians, the majority of whom are fair-skinned(浅肤色的), are four times more likely to develop a melanoma than people in Canada, the United States or Great Britain.The information about Rose Bengal is wrong EXCEPT that .

Deserts are found where there is little rainfall or where rain for a whole year falls in only a few weeks time. Then inches of rain may be enough for many plants to survive if the rain is spread throughout the year. If it falls within one or two months and the rest of the year is dry, those plants may die and a desert may form.
Sand begins as tiny pieces of rock that get smaller and smaller as wind and weather wear them down. Sand dunes (沙丘) are formed as winds move the sand across the desert. Bit by bit, the dunes grow over the years, always moving with the winds and changing the shape. Most of them are only a few feet tall, but they can grow to be several hundred feet high.
There is, however, much more to a desert than sand. In the deserts of the Southwestern United States, cliffs (悬崖) and deep valleys were formed from thick mud that once lay beneath a sea more than millions of years ago. Over the centuries, the water dried up. Wind, sand, rain, heat and cold all wore away at the remaining rocks. The faces of the desert mountains are always changing — very, very slowly — as these forces of nature continue to work on the rock.
Most deserts have a surprising variety of life. There are plants, animals and insects that have adapted to life in the desert. During the heat of the day, a visitor may see very few signs of living things, but as the air begins to cool in the evening, the desert comes to life. As the sun begins to rise again in the sky, the desert once again becomes quiet and lonely.Many plants may survive in deserts when ________.
| A．the rain is spread out in a year |
| B．the rain falls only in a few weeks |
| C．there is little rain in a year |
| D．it is dry all the year round |
Sand dunes are formed when ________.
| A．sand piles up gradually |
| B．there is plenty of rain in a year |
| C．the sea has dried up over the years |
| D．pieces of rock get smaller |
The underlined sentence in the third paragraph probably means that in a desert there is ________.
| A．too much sand |
| B．more sand than before |
| C．nothing except sand |
| D．something else besides sand |
It can be learned from the text that in a desert ________.
| A．there is no rainfall throughout the year |
| B．life exists in rough conditions |
| C．all sand dunes are a few feet high |
| D．rocks are worn away only by wind and heat |
A university graduate described as a “respectable and intelligent” woman is seeking professional help after being convicted of (证明有……罪) shoplifting for the second time in six months.
Ana Luz, recently studying for her PhD, has been told she could end up behind bars unless she can control the desire to steal from shops.
Luz, who lives with her partner in Fitzwilliam Road, Cambridge, admitted stealing clothes worth ￡9.95 from John Lewis in Oxford Street, London, on March 9.
Phillip Lemoyne, prosecuting (起诉), said Luz selected some clothes from a display and took them to the ladies’ toilet in the store .When she came out again she was wearing one of the skirts she had selected, having taken off the anti-theft security alarms (防盗警报装置).
She was stopped and caught after leaving the store without paying, Mr Lemoyne said.
He added that she was upset on her arrest (逮捕) and apologized for her actions.
Luz, 28, was said to have been convicted of shoplifting by Cambridge judges last October, but Morag Duff, defending, said she had never been in trouble with the police before that.
“She is ashamed and embarrassed (尴尬的) but doesnt really have any explanation why she did this, Miss Duff said. She didnt intend to steal when she went into the store. She is at a loss to explain it. She is otherwise a very respectable and intelligent young lady. She went to her doctor and asked for advice because she wants to know if there is anything in particular that caused her to do this.
Judge David Azan fined Luz ￡50, and warned, “You’ve got a criminal record. If you carry on like this, you will end up in prison, which will ruin your bright future you may have.”
Luz achieved a degree in design at university in her native Spain, went on to a famous university in Berlin, Germany for her master’s degree and is now studying for a PhD at Cambridge University, UK.What is Ana Luz’s nationality?

I fell in love with England because it was quaint (古雅) — all those little houses, looking terribly old-fashioned but nice, like dolls’ houses. I loved the countryside and the pubs, and I loved London. I’ve slightly changed my mind after seventeen years because I think it’s an ugly town now.
Things have changed. For everybody, England meant gentlemen, fair play, and good manners. The fair play is going, unfortunately, and so are the gentlemanly attitudes and good manners —people shut doors heavily in your face and politeness is disappearing.
I regret that there are so few comfortable meeting places. You’re forced to live indoors. In Paris I go out much more, to restaurants and nightclubs. To meet friends here it usually has to be in a pub, and it can be difficult to go there alone as a woman. The cafés are not terribly nice.
As a woman, I feel unsafe here. I spend a bomb (a lot of money) on taxis because I will not take public transport after 10 pm. I used to use it, but now I’m afraid.
The idea of family seems to be more or less non-existent in England. My family is well united and that’s typically French. In Middlesex I had a neighbour who is 82 now. His family only lived two miles away, but I took him to France for Christmas once because he was always alone.The writer doesnt like London because she _________.
| A．is not used to the life there now |
| B．has lived there for seventeen years |
| C．prefers to live in an old-fashioned house |
| D．has to be polite to everyone she meets there |
Where do people usually meet their friends in England?
| A．In a café. | B．In a restaurant. |
| C．In a nightclub. | D．In a pub. |
The underlined part it (in para. 4) refers to_________.
| A．a taxi | B．the money |
| C．a bomb | D．public transport |
The writer took her neighbour to France for Christmas because he _________.
| A．felt lonely in England |
| B．had never been to France |
| C．was from a typical French family |
| D．didnt like the British idea of family |
Perhaps you have heard a lot about the Internet，but what is it?
The Internet is many different networks around the world. A network is a group of computers put together. These networks joined together are called the Internet．
Maybe that doesn’t sound interesting. But when we’ve joined the Internet, there are lots of things we can do．We can find lots of interesting information on the World Wide Web(www)．We can use the Internet instead of a library to find all kinds of information for our homework. We can find information about our favourite sports or film stars and do shopping on the Inter-net. We can also send messages to other people by e-mail. It is much cheaper and quicker than calling our friends or sending a letter.
Thanks to the Internet, the world is becoming smaller and smaller. People can now work at home with a computer in front of them, getting and sending the information they need. They can buy or sell whatever they want by the Internet. But do you know 98％of the information is in English? So what will English be like tomorrow?The passage is mainly about________.
