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

About 5,000 children die each day due to preventable diseases such as cholera and dysentery (痢疾) , which spread when people use unclean water for drinking or cooking. A lack of water for personal health leads to the spread of totally preventable diseases like trachoma, which has blinded some six million people.
Water troubles also trap many low-income families in a cycle of poverty and poor education and the poorest suffer most from lack of access to water. People who spend much of their time on ill health, caring for sick children, or collecting water at distances averaging 3.75 miles a day don’t have educational and economic opportunities to better their lives.
Agriculture is called the lion's share of freshwater worldwide, using some 70 percent, and industrial uses consume another 22 percent. Water areas have no political borders and nations don't always work together to share common resources, so water can be a frequent source of international conflict as well.
Day-by-day demand keeps growing, further needing water sources, from great rivers to groundwater. “We’re going deeper into debt on our groundwater use,” Postel said, “and that has very significant impacts on global water security. The rate of groundwater consumption has doubled since 1960.”
Some of Earth's groundwater is fossil water created when Earth's climate was far different. Today such water is as limited as petrol. “But we're pumping much of them out faster than ever,” Postel explained. “Humanity's growing thirst also causes a major problem about water and our ecosystems. And that also creates a cost to us, to our sons and to our grandsons, not just to nature.”
1.What does the author mainly discuss in the passage?
A. Water shortage has been a most serious challenge.
B. So many children die of polluted water every day.
C. Diseases should be properly controlled and treated.
D. Wasting water leads to the unrest of the world.
2.Why is agriculture called the lion’s share of freshwater ?
A. Because agriculture is much stronger than industry.
B. Because more people live on the agricultural produce.
C. Because agriculture uses about two-thirds of freshwater.
D. Because nations don’t always work together to save water.
3.According to what Postel said we can know ____________.
A. groundwater is rich for us to use
B. there is no need to dig deep for groundwater
C. we are consuming our next generations’ water
D. we should use river water instead of groundwater
4.What can we infer form the passage?
A. We shouldn’t use water from rivers.
B. We should protect our ecosystems.
C. Water should be distributed equally.
D. Laws should be passed for groundwater.
