Tourism probably started in Roman times. Rich Romans visited friends and family who were working in another part of the Roman empire. But when the empire broke down, this kind of tourism stopped.

    In the early 17th century, the idea of the “Grand Tour” was born. Rich young English people sailed across the English Channel（英吉利海峡）. They visited the most beautiful and important European cities of the time, including Paris in France, and Rome and Venice（威尼斯）in Italy. Their tours lasted for two to four years, and the tourists stayed a few weeks or months in each city. The “Grand Tour” was an important part of young people's education—but only for the rich.

    In the 18th century, tourism began to change. For example, people in the UK started to visit some towns, such as Bath to “take the waters”. They believed that the water there was good for their health. So large and expensive hotels were built in these towns.

    In the 19th century, travel became much more popular and faster. When the first railways were built in the 1820s, it was easier for people to travel between towns, so they started to go for holidays by the sea. And some started to have holidays in the countryside as cities became larger, noisier and dirtier.

    Traveling by sea also became faster and safer when the first steamships were built. People began to travel more to far-away countries.

    The 20th century saw cars become more and more popular among ordinary people. Planes were made larger, so ticket prices dropped and more people used them.

    Thus tourism grew. In 1949, Russian journalist Vladimir Raitz started a company called Horizon Holidays. The company organizes everything—plane tickets, hotel rooms, even food—and tourists pay for it all before they leave home. The package tour and modern tourist industry was born.

    The first travel agency in China was set up as early as 1949. But tourism did not take off until 1978. In 2002, the industry was worth 500 billion Yuan and became an important part of China's social development.

    Be a Green Child

    What does it mean to be green? “Green” is more than just a color.{#blank#}1{#/blank#} Why green? Plants are green, and without them the Earth wouldn't be such a lovely home for us human beings. What can we do? Here's a four-step guide to being green.

    Reduce It!

    {#blank#}2{#/blank#} For instance, a shorter shower means you used less water and less fuel since your house uses to run the heater that warmed up the water.

    Reuse It!

    Sometimes people call ours a “throwaway society”. It means that we're a little to willing to throw away old stuff (东西) and buy new stuff.{#blank#}3{#/blank#}

    For instance, if your baby brother becomes older and loses interest in his plastic basketball hoop (篮圈), why not give it to another family who has a little kid?

    Recycle It!

    Recycling has never been easier. Many communities will pick it up right in front of your house and some towns even require it. Recycled goods go to a recycling center, where they can be turned into new cans, bottles, and paper.

    Enjoy It!

    It's true that rubbish and pollution are problems, but the Earth remains a huge and beautiful place that's ready for you to explore.{#blank#}4{#/blank#} Go for a hike, visit local nature centers and gardens, and climb up mountains.

    But before you travel the globe, take a look at your own backyard. Is there a spot where you could plant a tree or put in a little fruit or vegetable garden? {#blank#}5{#/blank#}

A. It also means taking special steps to protect the environment.

B. Many times, even if you no longer need something, someone else just might.

C. You can start locally by visiting the naturally beautiful spots in your city.

D. Turn off the water when you're brushing your teeth.

E. Get out there and get your hands dirty.

F. You can watch with pride as your tree takes root and your garden plants grow.

G. When you use less of something, you do a good thing for the Earth.

    Getting older is a natural part of life. Changes as you get older are usually gradual. Certain physical changes are common. How fast your body can burn calories slows over time, which means that your body needs less food energy than before.

    How much and how well you sleep will likely change. Most people start needing reading glasses around forty, and many have some hearing loss later in life. Starting in your fifties, bone aging increase. How you feel as you get older depends on many things, including what health problems run in your family and the choices you make.

    If your family members have diseases or chronic (慢性的) health problems like high blood pressure, then you may have a greater chance of having those problems yourself. But it doesn't mean you will definitely have the same problems. Actually, the lifestyle choices you make can help reduce your chances of getting illness that run in your family. And even if you do get a family illness, choosing to be physically active, to eat healthy foods, and to learn how to deal with stress can keep the illness from destroying your ability to enjoy your golden years.

    What do you need to do to feel your best as you age? One of the most important things you can do for your health at any age is to be physically active. Physical activity keeps your body strong, and it helps with how you feel. People who stay active are less likely to get depressed.

    Your mental and emotional health is also important. Protect or improve your emotional health by staying in touch with friends, family, and the community. People who feel connected to others are more likely to feel happy than those who do not.

                                                                                                   Money Matters

    Parents should help their children understand money. {#blank#}1{#/blank#} So you may start talking about money when your child shows an interest in buying things, candy or toys, for example.

    ⒈The basic function of money

    Begin explaining the basic function of money by showing how people trade money for goods or services. It is important to show your child how money is traded for the things he wants to have. If he wants to have a toy, give him the money and let him hand the money to the cashier (收银员). {#blank#}2{#/blank#} When your child grows a bit older and understands the basic function of money, you can start explaining more complex ways of using money.

    ⒉Money lessons

    Approach money lessons with openness and honesty. {#blank#}3{#/blank#} If you must say no to a child's request to spend money, explain, “You have enough toy trucks for now.” Or, if the request is for many different things, say, “You have to make a choice between this toy and that toy.”

    ⒊{#blank#}4{#/blank#}

    Begin at the grocery store. Pick out two similar brands of a product— a name-brand butter and a generic (无商标产品)，for example. You can show your child how to make choices between different brands of a product so that you can save money.{#blank#}5{#/blank#} If he chooses the cheaper brand, allow him to make another purchase with the money saved. Later, you may explain how the more expensive choice leaves less money for other purchases.

A. Wise decisions.

B. The value of money.

C. Permit the child to choose between them.

D. Tell your child why he can —or cannot — have certain things.

E. Ask yourself what things that cost money are most important to you.

F. Talk about how the money bought the thing after you leave the toy store.

G. The best time to teach a child anything about money is when he shows an interest.

    Are you interested in higher education in the United States? The following advice might help you.

    College, University or Institute

    College and universities offer undergraduate degrees in arts and sciences. And both can help prepare young people to earn a living. But many colleges don't offer graduate studies. Universities are generally bigger, offer more programs and do more research. An institute of technology can offer a wide choice of programs and activities. Seventy-five percent of freshmen go there with a strong interest and involvement in the arts.

    The Application Process

    International admissions officers advise students to apply to at least three schools. You may be able to apply online and pay the application charge with a credit card, or by mail. You should study the websites of schools to find information about how and when to apply, how much it will cost and whether any financial aid is available.

    Get a Student Card

    If you request a visa for the first time, you will have to go to an American embassy or consulate(领事馆). You will need to bring a government form sent to you by your American school that shows you have been accepted. A consular official will also take your picture and your fingerprints. You will also need banking and tax records that show you have enough money to pay for your education.

    Financial Aid

    American schools provide aid, like scholarships, fellowships, to almost half of foreign graduate students, but only ten percent of undergraduates. But grants, which, unlike a loan, does not have to be paid.

    On a recent spring morning. Susan Alexander, a retired government intelligence analyst, left her Maryland home, climbed into her Volkswagen Passat and drove about three miles to pick up two strangers. She battled rush-hour traffic on the Capital Beltway and George Washington Memorial Parkway before dropping them off at Reagan National Airport. She didn't earn a cent for her trouble, and that was the point.

    Alexander is a member of the Silver Spring Time Bank-one of more than 100 such exchanges around the world trying to build community by exchanging time credits for services instead of dollars and cents. "I have time," she said. "I like giving the gift of time to other people."

    In Alexander's case, passengers Mary and Al Liepold were grateful for the ride, but it wasn't charity. Mary, a retired writer and editor for nonprofit organizations, used time credits she banked for editing work and baking. Senior citizens who don't drive, the Liepolds cashed in their credits to catch a flight to Montreal for a five-day vacation.

    Without money changing hands or shifting between virtual accounts, the airport drop-off was more like a coffee party than a taxi ride. Driver and passengers chatted about projects they've completed for the time bank, and no one raised an eyebrow when Mary said she likes "to avoid the conventional economy."

    "The beauty of this is that you make friends," Mary Liepold said. "You don't just get services."

    The Silver Spring Time Bank formed in 2015 and has about 300 members, said co-founder Mary Murphy. Last year, she said, l,000 hours were exchanged for basic home repairs, dog walking, cooking and tailoring, among other services, without the exchange of money. "You get to save that money that you would have spent," she said. "You get to meet somebody else in your community and get to know that person. That's a bonus that's part of an exchange."

    A deal performed partly to make friends would seem to go against classical economics and one of Benjamin Franklin's most memorable sayings: "Time is money." To those at the forefront of modem time-banking, that is the appeal.
