Eyesight plays avery important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight:
•Schedule yearly exams.Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eyeglasses.
•Protect against UV rays(紫外线).Longterm stay in the sun creates risk to your eyes. No matter what the season is, it's extremely important to wear sunglasses.
•Give your eyes a break. Twothirds of Americans spend up to seven hours a day using computers or other digital products. Experts recommend that people practice the 20/20/20 rule: every 20 minutes, take a 20second break and look at something 20 feet away.
•As part of a healthy diet, eat more fruits and vegetables each day. Vitamins(维生素) C and E help protect eyesight and promote eye health.
•Practice safe wear and care of contact lenses(隐形眼镜).Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact lenses, many are breaking the rules and putting their eyesight at risk. Otherwise, you may have problems such as red eyes, pain in the eyes, or a more serious condition.
A.Eat your greens.
B.Eye care should begin early in life.
C.They can properly protect your eyes.
D.Stay in good shape by taking more Vitamins.
E.Parents usually don't care about their own eyesight.
F.Always follow the doctor's advice for appropriate wear.
G.This frequent eye activity increases the risk for eye tiredness.
Lindsay Renwick, the mayor of Deniliquin, a country town in New South Wales, misses the constant whir(嗡嗡声)of the rice mill whose giant fans dried the rice. The Deniliquin mill, the largest rice mill in the Southern Hemisphere (南半球), once processed enough grain to meet the needs of 20 million people globally. But six years of drought have had a destructive effect, reducing Australia's rice crop by 98 percent and leading to the mothballing of the mill last December.
Drought affects every agriculture industry based in Australia, not just rice – from sheep farming, the country's other backbone, to the cultivation of grapes for wine, the fastest-growing crop there, with that expansion often coming at the expense of rice. The drought's effect on rice has produced the greatest impact on the rest of the world, so far. It is one factor contributing to skyrocketing prices, and many scientists believe it is among the earliest signs that a warming planet is starting to affect food production.
Researchers are looking for solutions to global rice shortages – for example, rice that blooms earlier in the day, when it is cooler, to fight against global warming. Rice plants that happen to bloom on hot days are less likely to produce grains of rice, a difficulty that is already starting to emerge in inland areas of China and other Asian countries as temperatures begin to climb. 'there will be problems very soon unless we have new varieties of rice in place,” said Reiner Wassmann, climate change director at the International Rice Research Institute (IRRI). The recent reports on climate change carried a warning that could make the news even worse: that existing models for the effects of climate change on agriculture did not yet include newer findings that global warming could reduce rainfall and make it more variable.
Yet the effects of climate change are not uniformly bad for rice. Rising concentrations (浓度) of carbon dioxide, the main greenhouse gas, can actually help rice – although the effect reduces or disappears if the plants face unnecessary heat, inadequate water, severe pollution or other stresses. Still, the flexibility of farmers here has persuaded some climate experts that, particularly in developed countries, the effects of climate change may be relieved, if not completely avoided. “I'm not as negative as most people,” said Will Steffen, director of the Fenner School of Environment and Society at Australian National University. “Farmers are learning how to do things differently.”
Meanwhile, changes like the use of water to grow wine grapes instead of rice carry their own costs, as the developing world is discovering. “Rice is an essential food,” said Graeme Haley, the general manager of the town of Deniliquin. “Wine is not.”

Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy, as there's no need for a lot of scientific terms or expensive lab equipment. {#blank#}1{#/blank#}.
Give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. {#blank#}2{#/blank#}, children can give more logical, complete and creative answers.
Watch your language. Once you have a child involved in a science discussion, don t jump in with "That's right" or "Very good". {#blank#}3{#/blank#}. But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying "That's interesting or "I have never thought of it that way before", or coming up with more questions or ideas. Never force a child to think. {#blank#}4{#/blank#}, as children are always thinking, without your telling them to.
What's more, giving them freedom to think can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target for your disagreement.
{#blank#}5{#/blank#} Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass (放大镜) and they'll understand why you want them to wash before dinner. Rather than saying that water evaporates (蒸发), set a pot of water to boil and let them watch the water level drop.
