Whether we’re 2 years old or 62, our reasons for lying are mostly the same: to get out of trouble, for personal gain and to make ourselves look better in the eyes of others. But a growing body of research is raising questions about how a child’s lie is different from an adult’s lie, and how the way we deceive changes as we grow.

“Parents and teachers who catch their children lying should not be alarmed. Their children are not going to turn out to be abnormal liars,” says Dr. Lee, a professor at the University of Toronto and director of the Institute of Child Study. He has spent the last 15 years studying how lying changes as kids get older, why some people lie more than others as well as which factors can reduce lying. The fact that children tell lies is a sign that they have reached a new developmental stage. Dr. Lee conducted a series of studies in which they bring children into a lab with hidden cameras. Children and young adults aged 2 to 17 are likely to lie while being told not to look at a toy, which is put behind the child’s back. Whether or not the child takes a secret look is caught on tape.

For young kids, the desire to cheat is big and 90% take a secret look in these experiments. When the test-giver returns to the room, the child is asked if he or she looked secretly. At age 2, about a quarter of children will lie and say they didn’t. By 3, half of kids will lie, and by 4, that figure is 90%, studies show.

Researchers have found that it’s kids with better understanding abilities who lie more. That’s because to lie you also have to keep the truth in mind, which includes many brain processes, such as combining several sources of information and faking that information. The ability to lie — and lie successfully  — is thought to be related to development of brain regions that allow so called “executive functioning”, or higher order thinking and reasoning abilities. Kids who perform better on tests that involve executive functioning also lie more.

    Being considered a leader in our society is indeed of high praise. Leadership means power, commands respect and, most important, encourages achievement. Unlike vitamin C, leadership skills can't be easily swallowed down. They must be carefully cultivated.

    Different from popular belief, most good leaders are made, not born. They learn their skills in their everyday lives. But which do they develop? How do they (and how can you) get others to follow?

    Always give credit. Many leaders note that the most efficient way to get a good performance from others is to treat them like heroes. Giving public credit to someone who has earned it is the best leadership technique in the world. It is also an act of generosity (慷慨) that's never forgotten.

    Giving credit is more effective than even the most constructive criticism (批评), which often hurts rather than helps.  Kenneth Blanchard, the author of The One-Minute Manager, agrees. "Catch people doing something right!" he says. Then tell everyone about it.

    Take informed risks. "The best leaders know that taking a risk is not a thoughtless exercise," says management adviser Marilyn Machlowitz. "Sky divers don't go up in an airplane without checking the parachutes (降落伞) beforehand."

    Because the idea of risk also carries with it the possibility of failure, many of us usually wait for others to take charge. But if you want to be a leader, you must learn to fail and not die a thousand deaths. Pick yourself up and start all over again.

    Encourage enthusiasm. (热情) "When people understand the importance of work, they lend their mental strengths," says Lee Ducat. But when they get excited about the work, all their energy gets poured into the job. That's a great force ! Is this the best way to create excitement? Be enthusiastic yourself - You will be followed by everyone.

1. The underlined word "cultivated" (Paragraph 1 ) roughly means ______.

   A. encouraged       B. compared            C. examined         D. developed

2. The part Always give credit tells us that a leader should ______.

   A. give helpful criticism                      B. regard others as real heroes

   C. praise people for their good performances      D. praise everyone

   A. not be afraid of any risks

   B. think twice before taking risks

   C. try to avoid any possible failures

   D. know what a thoughtless exercise is

4. Which of the following can be the best title for the passage?

   A. Leadership Is of Skills and Techniques      B. Leadership Is Very Important

Supermarkets are trying out new computers that make shopping carts more intelligent(具备智能的). They will help shoppers find paper cups or toilet soap, and keep a record of the bill.

The touch-screen devices(触摸屏装置) are on show at the Food Marketing Institute’s exhibition here this week, “These devices are able to create value and get you around the store quicker,” said Michael Alexander, manager of Springboard Retail Networks Inc., which makes a smart cart computer called the Concierge.

Canadian stores will test the Concierge in July. A similar device, IBM’s “Shopping Buddy”, has recently been test-marketed at Stop & Shop stores in Massachusetts.

Neither device tells you how many fat grams or calories are in your cart, but they will flash you with items on sale. The idea is to make it easier for people to buy, not to have second thoughts that maybe you should put something back on the shelf.

“The whole model is driven by advertisers’ need to get in front of shoppers,” said Alexander. “They’re not watching 30-second TV ads anymore.”

People can use a home computer to make their shopping lists. Once at the store, a shopper can use a preferred customer card to start a system(系统) that will organize the trip around the store. If you’re looking for toothpicks, you type in the word or pick it from a list, and a map will appear on the screen showing where you are and where you can find them.

The device also keeps a record of what you buy. When you’re finished, the device figures out your bill. Then you go to the checker or place your card into a self-checkout stand and pay.

The new computerized shopping assistants don’t come cheap. The Buddy devices will cost the average store about $160,000, and the Concierge will cost stores about $500 for each device.

1. The underlined word “they” (paragraph 1) refers to ______.

2. Which of the following is the correct order of shopping with computerized shopping carts?

a. Start the system.         b. Make a shopping list.

c. Find the things you want.   d. Go to a self-checkout stand.

3.We can learn from the last paragraph that ______.

4. What might be the most suitable title for the text?

Normally when I pop in to see my parents, my mum bursts out of the house with a big smile. Not today. "Your brother," she says, "he's showered twice this afternoon. Does he know how much it costs to run this house?" Are we limiting water now? I didn't think the recession(萧条) had got that bad. My poor brother is a boomerang kid. Like 60 percent of guys immediately after university, he's back at home. Graduating ￡15,000 in debt and faced with unpaid internships(实习期) or low wages thanks to the flooding of the market with graduates, a lot of twenty some things simply don't have the necessary income or parental support to live independently.

Three years after getting their degree, most graduates are still not earning above the average salary. They have a near 50 percent tax burden, thanks to student loan repayments and council tax on top of income tax and national insurance. Unless you have parents who can afford to finance what is effectively a second home for them, returning to the parental nest is often the only affordable option.

The boomerang effect is becoming even more pronounced thanks to the recession. One in four of those losing their job during the downturn is under 25. Only 13 percent of final-year students have jobs. Home is the only place many are going: 111,000 16-29 year olds moved back home in 2008, five times the average of previous years.

Boomeranging is bad news. It poses serious problems for parents' finances. They've already supported their children through university, topping up loans with handouts, averaging ￡12,300 in total, to keep twenty somethings afloat. Now their retirement savings are being eaten away by continuously dependent children.

It’s bad for the returning kids too. Ambitious young people will be left frustrated, seeing their university peers from more wealthy backgrounds excel only because parents' money was there to support them through the initial period of poverty wages. Those living in rural areas are further disadvantaged by lack of access to cities where most new jobs are located. Half of all young people now feel they will not achieve their goals. Research by the Prince's Trust reveals that one-quarter of all 16-25 year olds are regularly down or depressed. And depression does not help self-motivation, the very trait needed to seek out job opportunities.
