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 director of the Institute of Child Study. 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.

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.

1. What’s the purpose of children telling lies?

A. To help their friends out.

B. To get rid of trouble.

C. To get attention from others.

D. To create a popular image.

2. From the second paragraph we can know that ____________.

A. which factors can reduce lying

B. why some lie more than others

C. it is normal for kids to tell lies

D. how lying changes as kids grow

3.It can be inferred from the passage that ________________.

A. children’s lies are the same as adults’

B. the better kids are, the more they lie

C. the older kids are, the more they lie

D. kids always keep the truth in their mind

4.What is NOT included in the passage?

A. The reasons why kids tell lies.

B. Which kind of kids tells more lies.

C. Experiments about lying of young kids.

D. What to do with lying children.

Alexis was hot and tired. With rage in her voice she shouted, "Pull me up!I give up, I hate this. This is stupid!" It was at that moment when Jason, the adviser on the trip, looked at me and said, "Ed, I'm going to go down and talk with her." I then shouted down to Alexis, "Hold on! You can do this. We know you can!"

Jason grasped another rope, put his climbing harness(系帶)on and began to move down the cliff. Within moments Jason was beside Alexis. She had her cheek directly against the face of the rock with her feet barely resting on a small piece of the cliff that stuck outward. Jason said to Alexis, "I know that you have been on this cliff now for what seems like a long time. Your feet and fingers are cramping(痙攣)up and your forearms feel as though they are on fire. But , Alexis, you are strong, look how far up you are already. You have taken one of the more difficult paths up the cliff. Alexis, look at the path you have taken."

At that moment, Alexis moved her cheek away from the rock face and looked down. The bright white chalk she used in her hands to give her a better hold, showed the path where her tired hands had moved her upward on the cliff. Jason was right. Alexis had taken the hardest way up the cliff. Jason then looked straight into Alexis' eyes and in a calm voice he said, "You are not alone out here, there are people who care about you, who want to help you and see you succeed. We are going to do this together. Are you ready?" Slowly she nodded her head and took a deep breath.

1.Jason went down the cliff because _________.

B. Alexis was trapped in rocks

C. Alexis didn’t believe in herself

D. Alexis’ forearms were badly hurt

4.Alexis would probably become _________.
