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.

    Hilversum is a medium-sized city between the major cities of Amsterdam and Utrecht in the Gooi area of North Holland, the Netherlands. Unlike most of the Netherlands, Hilversum is actually in a hilly area with the soil mostly consisting of sand. Once called the Garden of Amsterdam, it still attracts travelers to come over to cycle and walk through the surrounding forests. They visit it for a relaxing day off from the urban madness. For Dutch people, Hilversum is all about textile (纺织) and media industries, and modern architecture.

    In history, Hilversum was largely an agricultural area. Daily life was marked by farming, sheep raising and wool production. A railway link to Amsterdam in 1874 attracted rich traders from Amsterdam to Hilversum. They build themselves large villas (别墅) in the wooded surroundings of the town. One of the families moving in was the Brenninkmeijers, currently the wealthiest family of the Netherlands. They moved in after big success in the textile industry and aided a substantial textile industry in Hilversum. But the textile boom lasted only several decades. The last factory closed in the 1960s.

    The change to a media economy started in 1920, when the Nederlandse Seintoestedllen Fabriek (NSF) established a radio factory in Hiversum. Most radio stations called in the large villas in the leafy areas of the town. Television gave another push to the local economy. Hilversum became the media capital of the Netherlands, and Dutch televison stars moved into the leafy neighborhoods surrounding the town.

    In the early 1900s, modern architcts W.M. Dudok and J. Duiker placed hundreds of remarkable buildings in Hilversum. These modern architectural masterpieces (杰作) are so many that Hilversum almost feels like an open air museum. Dudok alone shaped most 20th century Hilversum and approximately 75 buildings in 1928-1931. It has wide international fame and is included in many architecture textbooks. The building has a remarkable shape and looks like a combination of “blocks”. Actually, one may start his journey of modern architecture by walking or biking the W.M. Dudok Architectural Route in Hilversum.

    Kung fu is one of a number of Chinese martial arts designed to improve the body and the mind. It is perhaps one of the most widely known martial arts, because many films include its techniques. There are hundreds of styles taught all over the world, although they can be loosely divided into two camps: Shaolin style kung fu, and other techniques, some of which have a history that outdates the Shaolin order.

    Shaolin kung fix has its origins in the fifth century. Like some other martial arts, it began in religious temples, where the monks sought a mind and body discipline (训练方法). In addition to the fighting style, it also includes mental exercises and religious practices designed to balance the whole body.

    Shaolin temples resembled universities, integrating a wide range of subjects of study. Therefore, traditional Shaolin styles such as Wing Chun, Crane, Praying Mantis, and Hung Gar took knowledge from fields outside martial arts, such as the healing arts and meditation. Supporters for Shaolin styles believe that they are more rounded martial arts styles, and that learners will benefit from them on a whole body level.

    Other fighting styles, some of which predate the Shaolin style, are also lumped under the kung fu umbrella. They include Pa-Kua, Eagle Claw, and Eight Drunken Immortals styles. These disciplines are not considered to be Shaolin style because they did not originate in temples and are focused primarily on fighting techniques.

    Whether Shaolin or otherwise, kung fu is characterized by self defense strategies that turn the energy of an attacker against him or her. Although the techniques may vary, most styles teach throws, kicks, punches, and the use of weapons. In addition to the physical discipline, most place a great importance on respect, honor, and living a balanced life.

    Many people believe that there is some truth in the saying Laughter is the best medicine.{#blank#}1{#/blank#} Laughter helps relieve pain, strengthen the immune system and reduce stress. Laughter stimulates(激发) hormones which make us feel happy. Laughter also increases the flow of blood throughout the body and has benefits which are similar to the ones you get by doing exercise.

    {#blank#}2{#/blank#}Children exposed to funny films and cartoons before major medical procedures are able to cope better with pain and anxiety.{#blank#}3{#/blank#} These are professional clowns who are sent to hospitals and wards to entertain and distract sick children.

    Laughter therapy has become very popular in recent years and as a result, more and more laughter clubs are starting to open up in cities and towns all over the world. At a laughter session, a trained therapist instructs the group to perform a series of exercises which are designed to produce laughter. {#blank#}4{#/blank#}And it takes them some time to get rid of their inhibitions(心理抑制).They might even start off with fake laughter, but this doesn't matter because our bodies can't tell the difference, and the results are the same. Moreover, laughter is contagious(传染的).{#blank#}5{#/blank#}

When it comes to having fun in the sun, it's easy to lose track of time. If you're not careful, this can be quite dangerous.{#blank#}1{#/blank#}But it can easily be prevented—all you need is a little sunscreen.

{#blank#}2{#/blank#}People have been using chemical pastes to protect themselves from the sun for centuries. But the first modern sunscreen sold on the market was offered by French company: L'oreal in 1935.

Several other companies were quick to release their own sunscreens. Perhaps the biggest advancement in the world of sunscreen came in the 1970s, when scientists started looking at the sun protection factor, or SPF.{#blank#}3{#/blank#}

The advantages of using sunscreen are obvious. It limits the painful effects of sunburn.{#blank#}4{#/blank#}Millions of people have died from skin cancer caused by ultraviolet rays from the SUITL. Remember to apply sunscreen 30 minutes before going outside.

Unfortunately, there are many mistaken ideas about sunscreen.{#blank#}5{#/blank#}Some also think you only need to put it on once for a whole day's protection or that you don't need it on cloudy days. None of these things are true. Experts say you should apply sunscreen every two hours when outside in the daytime, no matter how dark your skin is or what the weather is like.

A. And it can even save your life.

B. Sunscreen is not exactly a recent invention.

C. Choosing a sunscreen isn't as simple as it used to be.

D. In direct sunlight, sunburn can occur in less than 15 minutes.

E. This rating is a number that shows how effective a sunscreen is.

F. It's believed that you don't need much sunscreen if you have dark skin.

G. Some think a good method is to cover as much as possible with protective clothing.

Going to concerts and live performances is a lot of fun. As a teen, you'll want to prepare for the event far in advance in order to ensure that your concert experience is enjoyable.

Check to make sure that the concert venue(场所) is for all ages.

Find a friend to go with.

For your safety, it's best not to attend concerts alone. {#blank#}3{#/blank#} If you're having trouble finding company, consider posting on Facebook, Twitter, or Instagram to see if other people in your social network are interested.

Buy tickets.

If the concert is for a popular band, figure out exactly when the tickets go on sale. {#blank#}4{#/blank#}Ticketmaster. com sells tickets for bigger shows, but if you're going to a smaller show, look online at the venue's website for information on how to buy tickets.
