We all know that if we want to keep our body in good shape we have to do physical exercise regularly as well as be careful with what we eat. What we tend to forget is that this goes for our eyes as well. Medical science confirms that a diet rich in carotenoids (类胡萝卜素) can help maintain good vision(维持好视力) and prevent against a number of eye diseases. Here's some advice about how to choose the right diet to keep your eyes healthy.
— Eat orange food. Fruits and vegetables with orange flesh are rich in carotenoids. In addition to carrots，oranges，pumpkins and sweet potatoes are also available. All of these contain high levels of carotenoids，which help to maintain good vision.
— Include dark green vegetables，such as spinach (菠菜) and broccoli (西兰花) in your diet, to act as natural sunglasses. Recent scientific studies have shown that these vegetables can help block (阻挡) the damaging UV radiation(紫外线辐射)from the sun's rays.
— Prevent some eye diseases with orange juice, yellow corn, whole milk, nuts and leafy vegetables. These foods are good sources of vitamins A, C, D and E. All of these are necessary to good eye health.
— Increase your intake of omega¬3 with some sea fish, and some other seafood. Omega-3 helps build cell walls and is especially beneficial to keeping eyes healthy .It also helps regulate the eye's internal pressure and helps the eye dry up excess fluid.

LONDON (Reuters) — Quiet please — Britain’ s Queen Elizabeth is preparing to have her swans counted. Buckingham Palace has announced that the annual Swan Upping, a tradition dating back to the 12th century which involves a census of the swan population on the River Thames, will be conducted by the Queen’ s official Swan Marker from July 20—24.
“With the assistance of the Queen’s Swan Warden, Professor Christopher Perrins of the University of Oxford, the swans and young cygnets (小天鹅) are also assessed for any signs of injury or disease，” Buckingham Palace said in announcing the count.
The process involves the Swan Marker, David Barber, rowing up the Thames for five days with the Swan Warden in traditional skiffs while wearing special scarlet uniforms and counting, weighing and measuring swans and cygnets.
It may seem eccentric, but it is very important to the Queen, According to custom, Britain’ s sovereign owns all unmarked, mute swans in open water, but the Queen now exercises the right only on stretches of the Thames and its nearby tributaries.
In medieval times, the Swan Marker would not only travel up the river counting the swans, but would catch as many as possible as they were soughtafter for banquets and feasts.
This year, the Swan Marker and the Swan Warden are particularly keen to discover how much damage is being caused to swans and cygnets by attacks from dogs and from discarded fishing tackle (渔具)．
It is also an important year because Queen Elizabeth has decided to join her team of Swan Uppers for part of the census. She will follow them up the river and visit a local school project on the whole subject of swans, cygnets and the Thames.
“Education and conservation are essential to the role of Swan Upping and the involvement of school children is always a rewarding experience，” Buckingham Palace said. In medieval times，________.
| A．swans were better protected than now |
| B．a lot of swans were killed by dogs |
| C．swans were a delicious dish on royal banquets |
| D．common people could catch the swans |

| A．remains almost unchanged in the past years |
| B．involves a lot of royal members |
| C．sometimes lasts longer than before |
| D．is always guarded by special soldiers |
This year, the Swan Marker and the Swan Warden mainly want to find out________.
| A．the exact number of swans and cygnets |
| B．how a local school project is going on |
| C．how much damage the swans and cygnets suffer |
| D．how education and conservation are carried out along the Thames |

Electric cars are dirty. In fact, not only are they dirty, they might even be more dirty than their gasoline-powered cousins.
People in California love to talk about “zero-emissions vehicles,” but people in California seem to be clueless about where electricity comes from. Power plants most all use fire to make it. Aside from the few folks who have their roofs covered with solar cells, we get our electricity from generators. Generators are fueled by something — usually coal, oil, but also by heat generated in nuclear power plants. There are a few wind farms and geothermal plants as well, but by far we get electricity mainly by burning something.
In other words, those “zero-emissions” cars are likely coal-burning cars. It's just the coal is burned somewhere else so it looks clean. It is not. It’s as if the California Greens are covering their eyes — “If I can’t see it, it’s not happening.” Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it. But when you take that gas (or another fuel) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat — at the generator, through the transmission lines, etc.
A gallon of gas may propel your car 25 miles. But the electricity you get from that gallon of gas won't get you nearly as far — so electric cars burn more fuel than gas-powered ones. If our electricity came mostly from nukes, or geothermal, or hydro, or solar, or wind, then an electric car truly would be clean. But for political, technical, and economic reasons, we don’t use much of those energy sources.
In addition, electric cars’ batteries which are poisonous for a long time will eventually end up in a landfill. And finally, when cars are the polluters, the pollution is spread across all the roads. When it’s a power plant, though, all the junk is in one place. Nature is very good at cleaning up when things are not too concentrated, but it takes a lot longer when all the garbage is in one spot. What does the underlined word“clueless” mean in paragraph 2?
| A．The California Greens are covering their eyes. |
| B．People in California love to talk about zero-emissions vehicles |
| C．People in California love to have their roofs covered with solar cells |
| D．People there have no idea that so far electricity mainly comes from burning coal, oil, etc. |
What is the main idea of the passage?
| A．Electric cars are not clean at all. |
| B．Electric cars are better than gasonline-powered ones. |
| C．People cast doubts on electric cars’batteries. |
| D．Gasonline is an efficient way to power a vehicle. |
The electricity we get from a gallon of gas may make our car run __________.
| A．not less than 25 miles. |
| B．more than 25 miles. |
| C．no less than 25 miles. |
| D．not more than 25 miles. |
According to the passage, electric cars _________.
| A．do not burn fuel and more environmental. |
| B．are toxic and it is difficult for nature to clean it up when their batteries are buried in one spot. |
| C．are very good at cleaning up when things are not too concentrated |
| D．are poisonous for a long time and will eventually end up in a landfill |
It can be inferred from the passage that __________.
| A．Being green is good and should be encouraged in communications |
| B．Electric cars are not clean in that we get electricity mainly by burning something. |
| C．Zero-emissions vehicles should be chosen to protect our environment. |
| D．Electric cars are now the dominant vehicle compared with gasoline-powered cousins. |
After spending a year in Brazil on a student exchange program, her mother recalled, Marie Colvin returned home to find that her classmates had narrowed down their college choices. “Everyone else was already admitted to college,” her mother, Rosemarie Colvin, said from the family home. “So she took our car and drove up to Yale and said, ‘You have to let me in.’”
Impressed—she was a National Merit(全国英才) finalist who had picked up Portuguese in Brazil—Yaledid, admitting her to the class of 1978, where she started writing for The Yale Daily News “and decided to be a journalist,” her mother said.
On Wednesday, Marie Colvin, 56, an experienced journalist for The Sunday Times of London, was killed as Syrian forces shelled the city of Homs. She was working in a temporary media center that was destroyed in the attack.
“She was supposed to leave Syria on Wednesday”, Ms. Colvin said. “Her editor told me he called her yesterday and said it was getting too dangerous and they wanted to take her out. She said she was doing a story and she wanted to finish it. ”
Ms. Colvin said it was pointless to try to prevent her daughter from going to conflict zones. “If you knew my daughter,” she said, “it would have been such a waste of words. She was determined, she was enthusiastic about what she did, it was her life. There was no saying ‘Don’t do this.’ This is who she was, absolutely who she was and what she believed in: cover the story, not just have pictures of it, but bring it to life in the deepest way you could.” So it was not a surprise when she took an interest in journalism, her mother said.
