    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.

How to Become a Lifelong Learner

    Learning doesn't stop just because school does. Making a commitment to yourself to learn something new every day, you will not only enjoy what you discover, but you will be able to apply your knowledge and become a teacher to future generations. Here are some steps to become a life­long learner. 

    Learn how you learn.{#blank#}1{#/blank#}Note what learning techniques are most efficient for you and use them as much as is practical, such as viewing online tutorials on websites like YouTube if you're more of a visual learner. 

    {#blank#}2{#/blank#}Try many different things so that you don't box yourself into believing you're only good at a few things. It's probable that you're good at many things, but you won't know until you've tried. 

    Look at learning as an exploration and opportunity, not a chore (琐事)．Don't just force yourself to learn things because they are important or necessary. {#blank#}3{#/blank#} Follow your heart, as well as your sense of duty. Do you remember the 8th grade history that you hated so much, with all those names and dates that seemed to mean nothing? The point was to bring you to learn details now, which will knit chunks of information together later.{#blank#}4{#/blank#}   

    Read, read, read.{#blank#}5{#/blank#}Reading is a gateway into other worlds and into the minds of your fellow human beings. And reading will help you to learn the discoveries and mistakes of others who have gone before you; reading is, in effect, a shortcut so that you don't have to learn things the hard way. 

A．Learn where your talents and interests lie.

B．It was a chore then, but it makes sense, now.

    How much do you know about Chicago, Illinois, in the United States? {#blank#}1{#/blank#} And it is! Chicago is actually the third most populous city in the US, right after New York City and Los Angeles, according to the US 2010 Census. “The Windy City” is Chicago's most famous nickname (绰号). {#blank#}2{#/blank#} The city lies right next to Lake Michigan and heavy gusts (一阵风) of wind blow through the city.

    {#blank#}3{#/blank#} In fact, TripAdvisor says that the Art Institute of Chicago is the No 1 place to visit in the city. It is not only a school, but also a world-class art museum.

    If you don't feel like visiting a museum, your best choice is to go to Millennium Park. This is one of my personal favorites. This park holds the famous Cloud Gate, and it looks kind of like a big reflective (反光的) bean. {#blank#}4{#/blank#}

    {#blank#}5{#/blank#} If you enjoy heights, go visit the famous Willis Tower! You can go up to the top of it and step out onto a glass box. You'll be standing over the city, but don't worry – it's completely safe. Doesn't Chicago sound like a fun city?

A. Many people enjoy taking photos in its reflection.

B. You might think it's a big city.

C. Chicago is very well known for its art and culture.

D. Chicago also offers other fun things to do.

E. The famous Cloud Gate is a new landmark in Chicago.

F. It is for good reason.

G. Forget the fact that Chicago is home to nearly 200 art galleries.

    Earth is home to around 7,000 languages, around half of which are expected to disappear by 2100.

    Languages disappear for many reasons. Sometimes younger generations stop learning a language because parents want children to fit in. {#blank#}1{#/blank#} Native American children of the late-19th century were required to attend boarding schools where educators forbade them from speaking their native languages.

    The United Nations ranks endangered languages according to their risk level. For example, a "critically endangered" language is one that even grandparents don't speak often. New York's Onondaga language is an example with only 50 speakers left. An "extinct" language has no speakers. It is gone forever. Alaska's Eyak language is one example. {#blank#}2{#/blank#}

    {#blank#}3{#/blank#}In the same way, different languages contribute to cultural diversity. Saving these languages benefits our understanding of other cultures. Languages can show how a society looks at the world and what it values. A language may describe something in a way that is funny, too. In Welsh, it rains not cats and dogs, but old wives and walking sticks.

    The Endangered Language Alliance wants to save languages from disappearing. {#blank#}4{#/blank#} However, its efforts are limited. If an endangered language is going to make a real comeback, it'll probably get its start in schools. For nearly 100 years, public schools in Hawaii did not teach the Hawaiian language. Now students can keep learning in Hawaiian from elementary schools to college and beyond.

    {#blank#}5{#/blank#} At least one did. In 1881, a Jewish linguist named Eliezer Ben-Yehuda brought the 3,000-year-old language Hebrew back to life. Today it is one of the official languages of the country of Israel, with more than 4 million speakers.

A. The last person who spoke it died in 2008.

B. Why should we save endangered languages?

C. Various animals and plants benefit our environment.

D. With just 5 speakers left, it is absolutely endangered.

E. Can a language with zero native speakers come back to life?

F. Sometimes societies force minorities to give up their language.

G. The nonprofit group finds native speakers and records their stories.

    Where you choose to stay can make or break your vacation experience. But even the most experienced travelers may not know the difference between the two main types of homes-away-from-home—hotels and motels. {#blank#}1{#/blank#} The answer isn't as simple as you'd think.

    These two types of lodging(住宿)have the same basic purpose—a place for travelers to sleep.{#blank#}2{#/blank#} For instance, they came to be for different reasons, and at very different times.

    The word “hotel” dates back to the 1600s and comes from a French word, hôtel. That word, just like the English one, referred to a place that provides lodging, meals, entertainment, and other services to travelers. {#blank#}3{#/blank#} This word dates back to the 1920s and combines the words “hotel” and “motor.” As America's major highway system developed, so did motels, filling the need for roadside stops for motorists traveling cross-country.

    {#blank#}4{#/blank#} Hotels tend to be built for longer stays, while motels are intended more for one-or two-night stops along a journey. Because of this, hotels are much more likely to have offerings like lounges, gyms, and entertainment.

    {#blank#}5{#/blank#} Want the place you stay to be just as much a part of your travel experience as anything else? Choose a hotel, Just need a place to pop in and out of to shower and sleep? A motel might be the better choice.

A. There are many secrets that hotels won't tell you.

B. But there are plenty of features that set them apart.

C. Have you ever stayed in a motel on your vacation?

D. Motels, on the other hand, are a much more recent lodging option.

E. Besides their first letters, is there any real difference between them?

F. So, in the end, it comes down to what you want from your trip and from your lodging.

G. There are also other differences that can help you figure out which type of place you're in.
