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.

Twelve-year-old Leonardo was born in a poor family in Bambamarca in Peru. He knew how to read but he had never seen a book in his life. So he asked the new priest（牧师）in his village to give him one. But there was no electricity. So Leonardo borrowed candles from the church and sat up all night reading it. The next morning, he was at the door of the priest asking for another book to read.
John Medcalf, the priest，was moved. He also realised that people would love to read if given a chance. But he knew how difficult it was for Leonardo and those in his village to get books. And yet, no one can be taught to read and write without books. To make people in a poor, faraway area grow to love books，they have to be with them. So he thought the only way was to bring books to people.
But how could this be done? Mobile libraries or car libraries would be too expensive and difficult to continue in the rocky, hilly land of Peru. So what other methods could be used?
Medcalf got a new idea from the barefoot（赤脚）doctors of China. And that was how the barefoot librarians（图书管理员）first appeared in the villages of northern Peru，almost thirty years ago.
The librarians began by going from village to village, lending books to villagers. They helped start The Rura1 Library Network of Peru.
At first，they were teachers of the village schools which these faraway libraries belonged to. But the teachers were not very interested in the job because it meant a lot of hard work. So, village leaders took on the job themselves.
Today, there are 600 village libraries across Peru. The barefoot librarians who walk up to 15 hours a day with bags of books are their lifeline.The first paragraph tells us that Leonardo ______ .
| A．had a lot of books |
| B．bought candles from others |
| C．enjoyed reading books |
| D．lived in the church |
The underlined word "this" in Paragraph 3 probably refers to “______ ”
| A．to grow to love books | B．to bring books to people |
| C．to read and write | D．to build a new library |
The passage doesn't mention ______.
| A．when the barefoot librarians appeared |
| B．who worked as village librarians at first |
| C．where Medcalf met Chinese doctors |
| D．how many village libraries Peru has today |
It can be inferred（推断）from the passage that ______．
| A．the first church in Peru was set up by John Medcalf |
| B．car libraries used to be popular in Leonardo's village |
| C．teachers were interested in bringing books to villagers |
| D．the barefoot librarians are important to village libraries |
It’s a too long story — 17 months to be exact — with an ending that’s short and sweet. Ruthie has, finally and happily, been reunited with her family.
The story goes back to October, 2005. Ruthie, 8 months old, was sitting on the back seat of the family car when her owner walked hurriedly into a Long Island store. When Nancy Noel returned a few minutes later, Ruthie was nowhere in sight.
Nancy Noel and her husband, Lincoln Werden, got in touch with Nassau County police, put up flyers (小传单) around their Manhasset neighborhood. But no sightings of Ruthie were reported. Until last week, that is, someone sent Ruthie to a Manhattan shelter after finding her walking slowly around the Bronx — 25 miles from where she was taken on that fateful October day.
And then, shelter workers searched Ruthie for a possible microchip (微芯片) — she had one fixed under her skin. It showed her family’s name and address. Ruthie was immediately reunited with Nancy Noel and her daughter, Sara Werden.
“We never thought we would see her again,” said Sara Werden. “We were just amazed.”
She’s no longer the tiny pup they last saw. In fact, Ruthie gained (增加) 10 pounds during her months away from home. She’s on a diet now, and has already lost one and a half pounds. Ruthie also has a new friend to play with.
