    The “swim-with-dolphins” tourist industry is becoming more popular every year with the increase of people's income. After all, it can cost a large amount of money to have this kind of holiday experience. So tour operators try to place eager swimmers as near as possible to the dolphins by trying to predict where the dolphins will be.

    Research has shown that while dolphins can move away if they do not want to interact (交流） with human swimmers, they do not like it at all if the swimmers slip into the water directly on top of them or if humans are in their path of travel. However, if swimmers enter the water to one side of them, the dolphins do not avoid the swimmers to the same extent.

    In all cases, the dolphins seem to have become more sensitive to the presence of the swimmers. For dolphins, swimming amongst or with humans is not necessarily a high priority. This research has shown that only 19% of any group of dolphins will participate in interaction. Young dolphins are the most likely to interact; they do seem curious about being with humans. It is believed that they see humans as “entertainment” and that the interaction is a new and unusual experience for them.

    It is frequently asked whether “swim-with-dolphins” tourism should be discontinued. The advice is that dolphins should be given enough periods of time throughout the day when they are not exposed to tourism. Permitted interactions should not be too disturbing to the dolphins since there could be mothers and calves (幼崽） present in dolphin groups. There should also be educational campaigns about the creatures and what is likely to cause danger to them.

    It is not easy to explain to someone that they cannot fulfill their lifelong dreams because the dolphins are resting, or that a mother dolphin and calf are in the area. But if we are to enjoy these remarkable animals and not just use them for our entertainment, then we must carefully monitor the “swim-with-dolphins” industry worldwide.

    Wealth starts with a goal saving a dollar at a time. Call it the piggy bank strategy(策略). There are lessons in that time-honored coin-saving container.

    Any huge task seems easier when reduced to baby steps. I f you wished to climb a 12,000-foot mountain, and could do it a day at a time, you would only have to climb 33 feet daily to reach the top in a year. If you want to take a really nice trip in 10 years for a special occasion, to collect the $15,000 cost, you have to save $3.93 a day. If you drop that into a piggy bank and then once a year put $1,434 in a savings account at 1% interest rate after-tax, you will have your trip money.

    When I was a child, my parents gave me a piggy bank to teach me that, if I wanted something, I should save money to buy it. We associate piggy banks with children, but in many countries, the little containers are also popular with adults. Europeans see a piggy bank as a sign of good fortune and wealth. Around the world, many believe a gift of a piggy bank on New Year's Day brings good luck and financial success. Ah, but you have to putsomethingin it.

    Why is a pig used as a symbol of saving? Why not an elephant bank, which is bigger and holds more coins? In the Middle Ages, before modern banking and credit instruments, people saved money at home, a few coins at a time dropped into a jar or dish. Potters(制陶工) made these inexpensive containers from an orange-colored clay(黏土) called “pygg,” and folks saved coins in pygg jars.The Middle English word

    for pig was “pigge”. While the Saxons pronounced pygg, referring to the clay, as “pug”, eventually the two words changed into the same pronunciation, sounding the “i” as in pig or piggy. As the word became less associated with the orange clay and more with the animal, a clever potter fashioned a pygg jar in the shape of a pig, delighting children and adults. The piggy bank was born.

Originally you had to break the bank to get to the money, bringing in a sense of seriousness into savings. While piggy banks teach children the wisdom of saving, adults often need to relearn childhood lessons. Think about the things in life that require large amounts of money— college education, weddings, cars, medical care, starting a business, buying a home, and fun stuff like great trips. So when you have money, take off the top 10%, put it aside, save and invest wisely.

    Last year, Claire Noble-Randall woke up at 5:30 am every morning. She had to catch two buses to arrive in time for first-period chemistry at Ingraham High School in Seattle, US.

    Ingraham starts at 8 am, but Noble-Randall often didn't go to sleep until after midnight. “It was really hard not to fall asleep in class,” she said.

Her mom solved the problem this year when she discovered that other parents had hired a private city tour bus to take their children to the school.

    “Now, she leaves the house at a much more reasonable time 7:10 in the morning…to catch the little tour bug at 7:23 am,” said her mother, Noelle Noble.

    That may be one way to help students get more sleep. But more than 3,300 people have signed an online petition (请愿) looking for a better solution from the Seattle school district. Those who have signed the petition want all high schools and middle schools to start no earlier than 8:30 am. Most of Seattle's high schools and middle schools start at 8 am or earlier.

    Later start times for teenagers is an idea that some parents around the nation, have wanted for years. They've provided plenty of scientific evidence that teenagers tend to be night owls and delayed start times improve their health, mood, attention, and, in some cases, learning.

    But attempts to delay start times for teenagers haven't worked. Coaches don't want late dismissals (放学) cutting into sports practices; community groups don't want to wait longer for gyms and fields and before- and after-school programs don't want to change their schedules.

    This time, however, they've got Seattle School Board. President Sharon Peaslee on their side. She herself is the mother of two high school students. Peaslee hopes other board members will pass her plan calling on the district to find a way to make the changes.

    A humpback, a kind of big whale, can weigh as much as 40 tons and reach 50 feet from nose to tail. That means they can easily overturn small boats and it can be a great trouble to anyone who jumps on the back of the animal.

    But that was just what Sam Synstelien did when he saw a humpback in trouble in Central California's Morro Bay. The animal was hopelessly tangled (缠绕) in a rope that was attached to a buoy (浮标).

    Synstelien, along with his partner Nicholas Taron, had already tried reporting the poor animal to the U. S. Coast Guard—but they were told it would be hours before rescuers could come. Hours, the fishermen thought, this whale didn't have. "If we wanted the humpback to survive we had to go to get it," Taron later said. "We thought there was no other choice for the whale; we decided to go for it. We were so excited then. I don't think we were that scared. "

    It's easy for Taron to say, of course. His role in the rescue was mostly in the cheering department. In the video, you can hear him shouting "Swim! Swim! Move! Just get it! Get it!" from the side of the boat while filming the entire rescue. "The humpback was just swimming in circles," Taron said. "You could tell it was stressed and being held to the bottom."

    The very agitated whale didn't take well to human intervention (介入) and even hit the boat with its huge tail with a lot of force. But Synstelien hung in there, and at last cut through the rope. And then with a sudden move, the humpback swam deep down beneath the waves. It wasn't much of a thank you, but Synstelien and Taron were happy.

According to research, about 21.5 million American children between the ages of six and seventeen are involved (参与的) in a team sport. {#blank#}1{#/blank#} But regardless of the reasons for getting involved, children can gain a lot from sports.

A 2006 report shows that taking up sports can increase both emotional and behavioral well-being in teenagers. And increased well-being can lead to higher confidence, which results in better overall performance. {#blank#}2{#/blank#} In addition, they usually get along well with people around them and are less likely to have bad or risky behavior.

{#blank#}3{#/blank#} Through this process, children develop social and leadership skills and learn the value of teamwork. Children involved in sports usually have stronger and better relationships with their schoolmates and a better understanding of people from different backgrounds.

Actually, sports give children an opportunity to communicate with adults in valuable and positive ways, which can help them develop closer relationships with adults. This effect is especially great when children don't get along well with their family members. {#blank#}4{#/blank#}

Although most effects of sports on children are good, there can be disadvantages. If the pressure to win is overemphasized (过分强调) or the expectations of parents or coaches become too great, kids may experience lots of stress. {#blank#}5{#/blank#} To avoid these bad effects, children should not overemphasize winning but focus on developing certain skills.

A. Being physically fit is linked to having a higher IQ.

B. They may take part in sports for fun or to develop some skills.

C. However, children hardly play sports when they become older.

D. It can cause worries, headaches, stomach aches, and muscle pain.

E. For example, children involved in sports are likely to do well in their studies.

F. Organized sports require children to work together to achieve a common goal.

G. Many children say sports have helped increase their conversations with parents.
