Scientists have found that human eyes are more likely to be damaged by UV rays while skiing in the snow-covered areas than sitting on the beach, according to a report by the UK newspaper.
The researchers at Kanazawa Medical University, Japan and American company Johnson & Johnson conducted the study together. They looked at the effects of light reflection on newly fallen snow on a ski trail in Ishikawa District, northern Japan. They compared the results with the levels of UV rays on a sand beach in southern Japan's Okinawa District.
They found that on the beach, eyes are exposed to a daily 260 kilojoules (千焦耳) of UV a square meter compared to 658 kilojoules in snow-covered areas.
The findings are supported by the Japan Meteorological (气象的) Agency. According to the agency, the reflection rate of UV light on beaches is often between 10 and 25 percent, compared to 80 percent in the new snow areas. The amount of light increased 4 percent with a 300-meter rise in height.
Most of us know that UV rays can harm the skin. That's why we wear sunscreen on our skin before we get out in the sun. But many of us may not realize that UV rays are also harmful to the eyes.
If your eyes are exposed to large amounts of UV radiation over a short period of time, you may experience a kind of sunburn of the eye, which is harmful. Your eyes will become red and feel a strange feeling. They may be sensitive to light. Fortunately, this is usually temporary and seldom causes permanent damage to the eyes.
Long-term exposure to UV radiation, however, can be more serious. Scientific studies and researches have shown that exposure to small amounts of UV radiation over a period of many years increases the chance of eye damage, which could lead to total blindness.
1.You would most likely find the article in .
A. a doctor's diary B. a travel journal

2.Which of the following statements is TRUE according to the passage?
A. Too much eye exposure to UV rays may cause total blindness.
B. Short-time exposure of the eyes to UV rays doesn't harm them at all.
C. Most people know that UV rays harm the eyes as well as the skin.

B. People don’t wear sunscreen while skiing as they do while sitting on the beach.

【四川省成都市第七中学2017届高三二诊】C
On 8th March this year, events marking International Women’s Day (IWD) were held in many countries around the world. In most countries the events have a political tone: they tend to celebrate the advances women have made towards economic, social and political equality with men, and to press for change in those areas of life where there is still progress to be made.
In other countries, meanwhile, 8th March is traditionally more about expressing an appreciation of women: it is a day on which men give presents to their wives, girlfriends and mothers, and it therefore has some similarities with St Valentine’s Day and Mother’s Day.
Back in 1911, the first IWD events in Austria, Denmark, Germany and Switzerland were certainly political. They were protests by women against forms of gender discrimination that would now be unthinkable in most parts of the world: almost nowhere were women allowed to vote, and Finland was the only country with any female members of a national parliament. The general expectation worldwide, across different continents and cultures, was that women would spend their lives largely in the home, devoting themselves to looking after their husbands and children. The rate of women who had paid employment was far lower than today, and when women did go out to work they typically earned very little, meaning they were economically dependent on men.
A century later, gender inequality in employment—particularly pay inequality—is still one of the hottest issues IWD tries to draw attention to: it remains common, of course, for women to earn less than men for doing exactly the same job.
Limited educational opportunities (there are many countries in which girls generally stay fewer years in school than boys) and domestic violence towards women have also been highlighted by events surrounding IWD in recent years.
And yet, as the IWD website notes, As just one example, to return to the issue of women elected to office, the change over the last hundred years has been significant. Since 1911, when the small group of women in the Finnish parliament (nineteen of them, to be exact) were the only females in public office worldwide, the governments of more than fifty different countries have been led by women. In 2011, at least one country in every continent has a female leader, including high-profile examples such as Brazil (Dilma Rousseff), Germany (Angela Merkel) and Australia (Julia Gillard).
1.According to the passage, which of the following is true?
A. 100 years ago, women were not allowed to work outside.
B. IWD is equal to St Valentine’s Day and Mother’s Day in some countries.
C. Finland was the first country with female employment.
D. Pay inequality is a hot issue for IWD.
2.Which word below is closest in meaning to the phrase “press for” in Paragraph 1?
A. prevent B. urge C. express D. want
3.Which of the following is the missing sentence in the first line of the last paragraph?
A. distinctive differences do exist between men and women
B. the achievements are beyond people’s expectations
C. there’s still a long way to go to achieve the set goals
D. alongside the ‘negatives’ there are plenty of ‘positives’
4.We can conclude from the passage that .
A. the progress in gaining equality in the last century seems to be too slow
B. the concept of equal pay for equal work is completely accepted in practice
C. much has been achieved in gender equality, but still there is space for improvement
D. one or two female leaders can’t stand for women’s social status on the whole

Chinese scientists have found a new way to use cells found in human urine （尿液）that could aid in the treatment of a range of nerve disorders.That is a new technique for reprogramming cells in human urine into nerve progenitor cells that can grow into multi-functional nerve and brain cells.
The technique is expected to be used in the study and treatment of nerve disorders such as Parkinson's disease, Alzheimer's disease and other nerve disorders.
Pei Duanqing, a professor at Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, said his research team has combined an episomal system to deliver reprogramming factors with a chemically defined culture medium to reprogram kidney epithelial(肾表皮) cells in urine into NPCs.
These NPCs, normally only found in the human brain, were later proven to be transgene-free and self-renewing, he said.
"These nerve and brain cells can survive for up to one month when transplanted into the brain of a newborn rat," said Pei. "My team is working hard to understand why our experimental condition allowed the urine cells to become NPCs, because we want to improve the technique and make it more efficient".
Scientists have long searched to treat and study neural disorders by obtaining and transplanting neural stem cells. However, the previous method of getting and using cells from either fetal (胎儿)or adult human tissue remains challenging due to ethical concerns and immune system rejections, he said.
Pei hopes the discovery will be used to generate NPCs from patients with nerve disorders such as Parkinson's disease. "These NPCs from patients may help us discover new drugs for these diseases."
"It is a remarkable advance in the stem cell field. The results and methods obtained from this study will be of great value and significance to the field, " said Fred Gage,a professor with the Salk Institute for Biological Studies.
1.What is the passage mainly about?
A. NPCs are beneficial in treating human diseases.
B. Chinese scientists succeeded in making NPCs from human urine.
C. Chinese scientists have found cures for all diseases.
D. A new technique was used to study the use of human urine
2.Pei and his tean try their best to work hard in order to________.
A. make more contributions to medical study
B. discover another new technique
C. make the technique more perfect
D. treat more patients suffering from bad diseases
3.What is the challenge of making NPCs in the previous method?
A. The ethical comcerns and immune system refusal
B. The difificulties in getting cells from human.
C. The under-developed techniques in medical science.
D. The lack of financial support from the government.
4.From the last paragraph we can infer________.
A. the new technique will be developed in science
B. the results and methods will be applied to treating cancers
C. the study will give a major push to the stem cell field
D. the mew technique will bring great profis
