As many as 60,000 people worldwide die each year from too much sun, but simple safety steps could prevent many deaths, according to a World Health Organization report.

The report, released on Wednesday, was treated as the first overall look at the global health burden from UV radiation, which is linked to up to 90 percent of melanoma（恶性黑色素瘤） and other skin cancers. UV radiation can also cause sunburn, more rapid skin aging, eye diseases, and reactivation of the herpes（疱疹） virus that causes cold sores, and pterygium, a fleshy growth on the surface of the eye.

“We all need some sun, but too much sun can be dangerous—and even deadly,” said Dr Maria Neira, the director of WHO’s agency of public health and the environment, who released the report.

To prevent cancer and other diseases linked to UV radiation, the agency recommends that people:

— Limit time in the midday sun.

— Use shade wisely and seek shade when UV rays are most intense.

— Wear protective clothing, hats and sunglasses.

— Use sunscreen with a sun protection factor 15+.

— Avoid sunlamps and tanning parlours.

People under age 18 should not use them at all.

“The application of sunscreens should not be used to prolong sun exposure but rather to protect the skin when exposure is unavoidable,” the report warned.

The report also noted that the ground’s surface can make a difference:

— Fresh snow reflects as much as 80 percent of ultraviolet light.

— Sea foam reflects about 25 percent.

— Dry beach sand reflects about 15 percent.

Small amounts of exposure to the sun help the skin to produce vitamin D.

48. The report was highly spoken of mainly because ____.

A. it had listed up to 60,000 deaths from UV radiation

B. it related the deaths to UV radiation

C. it showed the advantages and disadvantages of UV

D. it found out the approaches to preventing deaths from UV radiation

49. According to Dr Maria Neira, which of the following is TRUE?

A. In fact we need only a small amount of sunlight.

B. Receiving large amounts of sunlight will cause deaths.

C. Midday sunlight has stronger UV radiation.

D. Melanoma will disappear if we follow the report’s advice.

50. As a construction worker, it is strongly recommended that ____.

A. he should stay inside the building                 B. he spread sunscreen on the face

C. he should wear good sunglasses                           D. he be equipped with sun protection

51. Which of the following can be the headline of the passage?

A. UV—A Deadly Killer From The Sun               B. Melanoma Can Be Prevented Today

C. UV—A Great Need For Vitamin D                   D. Teenagers Mustn’t Stay Outside

A new factory that turns used wine bottles into green sand could revolutionize the recycling industry and help to filter（过滤）the nation's drinking water.

For the last 100 years special high grade white sand quarried（开采）at Leighton Buzzard in Bedfordshire has been used to filter tap water to remove bacteria and impurities—but this may no longer be necessary.

The green sand has already been successfully tested by water companies and is being used in 50 swimming pools in Scotland to keep the water clean.

Backed by one million pounds from the European Union and the Department for Environment, Food and Rural Affairs(Defar),a company based in Scotland is building a factory to turn beverage bottles back into the sand from which they were made.

The idea is not only to avoid using up increasingly scarce sand in Scotland and avoid any further quarrying but also to solve a crisis in the recycles only 750 000 tones of it.

Howard Dryden, the scientist and managing director of the company has spent six years working on what he calls Active Filtration Meadia, or AFM, the recycled glass. He says he needs bottles that have already contained drinkable liquids to be sure that drinking water would not be polluted.

"The fact is that tests show that AFM does the job better than glass, it is easier to clean and reuse and has all sorts of properties that make it ideal for other applications, "he claimed. He also thinks the market will be able to take 250 000 tones of green sand a year. The plan is to build five or six factories in cites in UK where the bottles come from to cut down on transport.

The factory will be completed this month and is expected to go into full production on January 14 next year. Once it is providing a "regular" product, the government's drinking water inspectorate will be asked to perform tests and approve it for general use by water companies.

1.It may no longer be necessary to use high-grade white sand to keep water clean because_____.

A.there is no need to keep water clean

B.A new factory has been set up

C.The green sand has been used to keep the water clean

D.White sand is being use up

2.According to the passage ,the new idea can do the following except_____.

A. avoiding using up increasingly scarce sand

B. avoiding further quarrying of white sand

C. solving the crisis in the recycling industry

D. cutting down the cost on transport

3.Tests show that ______ in keeping the water clean.

A .AFM is more efficient than white sand

B.AFM is more efficient than glass

C. glass is more efficient than AFM

D. white sand is more efficient than green sand

4.The underlined word "Backed" in the third paragraph can best be replaced by"_____".

A. Allowed             B. Opposed

C. Supported            D. Forbidden

5.What would be the best title for the passage?

A. Revolution in the Recycling for the Industry.

B. Modern Technology an New Markets.

C. Revolution in Environmental Protection.

D. Unlocking the Benefits of Green Sand.

BE A GOOD TOURIST

Tourism can be both good and bad. Yes, it brings in money for the local economy and creates lots of jobs for locals, but it may also bring some problems.

1. Tourists have used paint, rocks, or even keys to write on the Luxor Temple in Egypt, the Colosseum in Rome, Stonehenge in the UK, memorial stones at the bottom of Qomolangma, and many, many other places. Thousands of tourists sites are being destroyed by tourists who “love them to death”. 2. If you want to leave a mark on the world, do it by changing someone’s life with kindness and love. Pass kindness along to future generations, not destruction.

Another big problem in some places has been tourists disturbing the local people and life. 3. For example, Chiang Mai University in Thailand and Yonsei University in South Korea have great numbers of tourists visiting their campuses and walking through their libraries and other public areas, taking pictures of students and disturbing their studies. I have three words for tourists like this: please be considerate. 4.

The number of problems from tourists is endless: walking in large groups without considering others who need to walk by, crossing roads without observing local traffic laws, and many more. The only way to solve the issue of the terrible tourist is to make sure that you are not one! 5. Remember, whenever you step outside your country’s borders, you are representing your country to the rest of the world.

A. Just think from other aspects.

B. When in Rome, do as the Romans do.

C. Have fun in a way that does not disturb others.

D. Be the best, kindest, most polite tourist possible.

E. I have three words for people like this: please stop it.

F. One growing problem is tourists who want to prove that they have visited someplace.

G. Some tourists wander around and take pictures of local people without asking for their permission.
