It is not unusual at all for teens to answer their parents with one work answers. “Where are you going?” “Places.” “When will you be back?” “Sometime.” “Who will you be with?” “People.”

That means that the days of your children bounding in the front door with the details of their day are over. They are breaking away from you so that they’ll be able to stand on their own as a young adult.

Some parents feel sad about this loss of their children’s closeness. Of course you miss those conversations and friendly talks. Once your children move out after high school and establish themselves confidently as a young adult, they’ll come back for easy conversations and even ask for advice. But in order to determine who they are right now they need to separate from you.

Your job, however, is to keep them safe——and that requires knowing there they are and who they are with. Let them know clearly that it’s not because you want to dominate their life and control them; it’s because it’s a safety issue for family members to keep track of one another.

When they’re home and sit down to eat a meal, sit down with them. You need to open up to them about your life. Tell them of an interesting incident at the office, let them in on a bit of family gossip(闲谈), discuss a piece of news with them. They are glad that you see them as old enough to be in on a few experiences of your life. By letting a teen in on your life, they just may let you in of theirs

Elephants are famous for their supposedly excellent memory. Now it seems that they are good at simple math too.
Researchers at the University of Tokyo have found an Asian elephant named Ashya can add small quantities together and correctly identify(识别）which is larger.
For example ,when researcher Naoko dropped three apples into one bucket and one apple into a second, then four more apples into the first and five into the second, Ashya correctly identified that the first bucket contained more apples and began munching(嚼）on her tasty prize.
Ashya chose the correct bucket 74% of the time "I even get confused when "I'm dropping the apple," Naoko told New Scientist magazine.
Elephants' counting abilities are far from unique. Chimps, pigeons(鸽子)and dolphins have shown the same abilities in lab tests, but what is more impressive for Elephants is that their ability to tell between two figures does not get worse when those numbers are more similar.
The elephants that Naoko tested were as good at telling the difference between five and six as they were at telling between five and one.
Naoko presented her findings last week at the International Society annual meeting in New York.
It is not obvious why elephants should need this mathematical ability in the wild." It is really tough to figure out why elephants would need to count," said Mya, a professor at Cornell University who studies elephants.
One possibility is that they use it to keep track of other members of their herd(兽群）so that no one is left behind. Asian elephants live in groups of six to eight." You really don't want to lose your group members," said Mya.
Another possibility is that the ability for simple math might be a by-product(副产品）of natural selection for a larger brain.

One hundred and thirteen million Americans have at least one bank-issued credit card. They give their owners automatic credit in stores, restaurants, and hotels, at home, across the country, and even abroad, and they make many banking services available as well. More and more of these credit cards can be read automatically, making it possible to withdraw or deposit money in scattered locations, whether or not the local branch bank is open. For many of us the “cashless society” is not on the horizon---it’s already here.

While computer offer these conveniences to consumers, they have many advantages for sellers too. Electronic cash registers can do much more than simply ring up sales. They can keep a wide range of records, including who sold what, when and to whom. This information allows businessmen to keep track of their list of goods by showing which items are being sold and how far they are moving. Decisions to reorder or return goods to suppliers can then be made. At the same time these computers record which hours are busiest and which employees are the most efficient, allowing personnel and staffing assignments to be made accordingly. And they also identify preferred customer for promotional campaigns. Computers are relied on by manufacturers for similar reasons. Computer analyzed marketing reports can help to decide which products to emphasize now, which to develop for the future and which to drop. Computers keep track of goods in stock, of raw materials on hand, and even of the production process itself.

Numerous other commercial enterprises, from theaters to magazine publishers, from gas and electric utilities to milk processors, bring better and more efficient services to consumers through the use of computers.

Most people believe they don’t have much imagination. They are __50__. Everyone has imagination, but most of us, once we become adults, forget how to __51__ it. Creativity isn’t always __52__ with great works of art or ideas. People at work and in their free time __53__ think of creative ways to solve problems. Maybe you have a goal to achieve, a tricky question to answer or you just want to expand your mind! Here are three techniques to help you.

Making connections  This technique involves taking __54__ ideas and trying to find links between them. First, think about the problem you have to solve or the job you need to do. Then find an image, word, idea or object, for example, a candle. Write down all the ideas/words __55__ with candles: light, fire, matches, wax, night, silence, etc. Think of as many as you can. The next stage is to relate the __56__ to the job you have to do. So imagine you want to buy a friend an original __57__; you could buy him tickets to a match or take him out for the night.

No limits!  Imagine that normal limitations don’t __58__. You have as much time/space/money, etc. as you want. Think about your goal and the new __59__. If your goal is to learn to ski, __60__, you can now practice skiing every day of your life (because you have the time and the money). Now __61__ this to reality. Maybe you can practice skiing every day in December, or every Monday in January.

Be someone else!  Look at the situation from a __62__ point of view. Good businessmen use this technique in trade, and so do writers. Fiction writers often imagine they are the __63__ in their books. They ask questions: What does this character want? Why can’t she get it? What changes must she make to get what she wants? If your goal involves other people, put yourself in their __64__. The best fishermen think like fish!
