Eyesight（视力) plays a very 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（安排）yearly exams(检查). {#blank#}1{#/blank#} 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). Long-term stay in the sun creates risk to your eyes. No matter what the season is, it's extremely important to wear sunglasses. {#blank#}2{#/blank#}

    Give your eyes a break. Two-thirds of Americans spend up to seven hours a day using computers or other digital products. {#blank#}3{#/blank#} Experts recommend that people practice the 20/20/20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.

    {#blank#}4{#/blank#} 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. {#blank#}5{#/blank#} 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（适当的）wear.

G．This frequent eye activity increases the risk for eye tiredness.

    When you travel in other countries, you'll have to get yourself well prepared to ensure your safety and handle emergencies.

Before you leave, you'd better:

1). Take out medical insurance policy and learn what the plan covers and whether departure or return to the hometown is covered. Figure out payment choices, such as whether you have to speak directly with the insurance company, before or after treatment, whether you have to pay first and get compensation later.

2). Keep up to date on all required vaccinations (接种疫苗) .

3). Learn about the city or area where you are going to travel. Know how to say street names and landmarks in the local language. Figure out unique climate issues such as altitude, seasonal changes, potentially risky animals and insects.

4). Visit some local hospitals and write down addresses in the local language along with emergency entrance locations; do the same for dental/pediatric (小儿科的) services. Get first aid equipment with necessary medications. Take enough prescribed medication from the home country.

5). Carry a card or note written in both English and the local language listing your emergency contact numbers, name, basic medical information such as blood type and allergies (过敏) .

6). Ensure a reliable means of communication is available and carry an extra phone battery and a charger. Ensure that housemaids, drivers, office assistants, those who work or travel know how to call for medical assistance since they may be the only ones available in an emergency.

7). Make sure to bring all documents and visas along with you. Plan your journey carefully and carry copies of documents (ID, insurance policy records, medical records) and keep in a place where someone else could access them in an emergency.

    Yesterday night, over a dinner with my elder brother's family, a topic of happiness came up. My wife, Marla, a psychologist, was sharing Csikszentmihalyi's concept of “flow” with us. Marla explained that according to the research on flow, people are happiest when they are absorbed in a task that is just challenging enough for them to experience a sense of mastery(熟练).

    A few moments later my brother, Yuri, offered the following opinion: “The first and only, necessary and sufficient factor for happiness is to stop associating happiness with pleasure. The two — happiness and pleasure — have nothing to do with each other.” This morning, with my cup of coffee, I searched through a pile of books on my bedside table and—at the bottom—found a book by Bertrand Russell, I started reading but didn't finish. In it, I found the following thought:

    “The human animal, like others, is adapted to a certain amount of struggle for life, and when by means of great wealth homo sapiens can gratify all his whims (突发奇想) without effort, the mere absence of effort from his life removes an essential ingredient of happiness.”

    The conversation came full circle: people are happiest when they are in a state of flow (Csikszentmihalyi's language )…which is the effortful devotion in a moment…which has nothing to do with pleasure.

    Indeed, as Yuri insisted : happiness–as–pleasure is a myth; the association between happiness and pleasure is nothing but a semantic(语义的) habit; psychologically, the two—happiness and pleasure—are arguably different; and breaking up this association between pleasure and happiness might, in fact, be a powerfully first step in pursuit of happiness.

    As I look back on that exchange, I recall that there was an effort, a struggle to find a common understanding about this seemingly difficult idea—a struggle that made me happy.

    Mandara seemed to know something big was about to happen. So she let out a yell, caught hold of her 2-year-old daughter Kibibi and climbed up into a tree. She lives at the National Zoo in Washington D.C.

    And on Tuesday, August 23rd, witnesses said she seemed to sense the big earthquake that shook much of the East Coast before any humans knew what was going on. And she's not the only one. In the moments before the quake, an orangutan (猩猩) let out a loud call and then climbed to the top of her shelter.

    “It's very different from their normal call,” said Brandie Smith, the zookeeper. “The lemurs (monkey like animals of Madagascar) will sound an alarm if they see or hear something highly unusual.”

    But you can't see or hear an earthquake 15 minutes before it happens, can you? Maybe you can——if you're an animal.

    “Animals can hear above and below our range of hearing,” said Brandie Smith. “That's part of their special abilities. They're more sensitive to the environment, which is how they survive.”

    Primates weren't the only animals that seemed to sense the quake before it happened. One of the elephants made a warning sound and a huge lizard (蜥蜴) ran quickly for cover. The flamingoes (a kind of birds) gathered before the quake and stayed together until the shaking stopped.

    So what kind of vibrations (震动) were the animals picking up in the moments before the quake? Scientist Susan Hough said earthquakes produce two types of waves——a weak “P” wave and then a much stronger “S” wave. The “P” stands for “primary”. And the “S” stands for “secondary”. She thinks the “P” wave might be what sets the animals off.

    Not all the animals behaved unusually before the quake. For example, Smith said the zoo's giant pandas didn't jump up until the shaking actually began. But many of the other animals seemed to know something was coming before it happened. “I'm not surprised at all,” Smith said.

The Advantages of Hobbies

    Hobbies provide entertainment and a chance to continuously learn something new and develop a skill set.{#blank#}1{#/blank#}

    Hobbies are praised as a key to stress reduction. Becoming lost in the mental concentration or physical action which you are deeply interested in helps you shift focus from the parts of life that are stressful.{#blank#}2{#/blank#}And in turn you are more peaceful when working on other work.

    {#blank#}3{#/blank#}Many people set goals with their hobbies that provide them satisfaction when these goals have been achieved. These goals can be simple, like improving a golf score, writing a certain number of pages for a novel each day or seeing an entire collection of classic films.

    Hobbies provide a sense of community when you meet other people who enjoy similar activities.{#blank#}4{#/blank#}More populated cities typically have numerous clubs or groups for people to share their knowledge and enthusiasm about a particular hobby. Becoming a member of one of these organizations allows greater growth within your hobby, as well as a chance to make new friends.

    Having a hobby can develop a talent that makes a person feel proud and satisfied. For example, a tennis hobby developed at a young age can lead to a career as a professional athlete one day.{#blank#}5{#/blank#}For example, writer Vladimir Nabokov also collected butterflies, which allowed him to do better in his chosen fields because he used learned skills from one to improve the other.

A.Focusing on something enjoyable can calm the mind.

B.Hobbies also provide a sense of achievement.

C.Some hobbies affect other aspects of your life.

D.There are a variety of hobbies.

E.They also provide many other social and health benefits.

F.Having a hobby increases the chances to interact with like-minded people.

G.Some hobbies containing physical activities offer an enjoyable way to stay healthy.

    Movies have documented America for more than one hundred years. Since Thomas Edison introduced the movie camera in 1893  amateur and professional movie-makers have used moving pictures to tell stories and explain the work of business and government. {#blank#}1{#/blank#} By preserving these movies, we will save a century of history.

    Unfortunately, movies are not made to last. {#blank#}2{#/blank#} Already the losses are high. Only 20% of US feature films from the 1910s to 1920s survive. Of the American features produced before 1950, about half exist. For independently produced works, we have no way of knowing how much has been lost.

    For many libraries and museums, the hardest step in preserving movie collections is getting started. The Movie Preservation Guide is designed for these organizations. {#blank#}3{#/blank#} These institutions have collections of moving pictures but lack information about how to take care of them. The guide contains basic facts for "beginners"—professionals trained in history but unschooled in this technical area.

    The guide grew from user workshops at Duke University. At the sessions, beginners talked with technical experts about what they needed to know to preserve and make available their movie collections. {#blank#}4{#/blank#}

    Following the advice, the guide describes methods for handling and storing moving pictures that are practical for research institutions with limited resources. {#blank#}5{#/blank#} The guide has been translated into Chinese, Japanese and Korean.

A. "Keep it simple!" was the advice of the discussions.

B. They'll be damaged within years if not properly stored.

C. These organizations are the first to save American movies.

D. It is organized in chapters and includes case studies and charts.

E. It introduces movie preservation to nonprofit and public institutions.

F. They show how generations of Americans have lived, worked and dreamed.

G. They store the original movies and new ones under cool-and-dry conditions.
