On countless mornings over the past year, I stood with my son, James, in our driveway, watching our neighbor hurry off to kindergarten. My wife and I wanted to give James the best education, but that meant we’d have to change our jobs and spend less time with our kid. I asked myself, “Would this trade-off be worth it?” When I look at the research on child development, I think it might not. Where our kids go to school might matter less than most American parents think.

Social scientists have long tried to determine why some children grow up to be successful. In a 2001 study, Greg Duncan, a professor of education at the University of California, measured the influence that the people in a child’s life have on how well the child does in school. Duncan and his team found almost no relationship between how students did on the test and whom they sat beside in class, whom they hung out with after school and who lived in their block. The only meaningful link they found was between siblings（兄弟姐妹）and twins in particular.

For a long time, scholars thought that a family’s income heavily affected how well kids did in life. But that might not be the case. When Susan Mayer at the University of Chicago looked at the relationship between family income and lifetime achievement, she ran a series of experiments to measure it, finding such outcomes weren’t caused by income. She argued that the things that make a difference are relatively inexpensive: the number of books a kid has or how often his family goes to museums.

Lareau, another scholar began one of the most in-depth observations of American parenting. He concluded that success is much more related to the amount of time parents spend with their children. He said “Many parents I interviewed are anxious about their children’s futures．But they have exaggerated（夸大）the sense of the risks involved if they don't give their children the best of everything..”

So at last, we decided to leave things as it were. More time with our kid is the best we can provide.

1.The first paragraph is intended to __________.

A. introduce the topic of the passage

B. confirm the result of a research

C. stress the importance of good education

D. support a research on child development

2.From the passage we know that most American parents _________.

A. spend a lot of time with their children

B. like to buy a variety of books for their children

C. think children's achievement largely depends on schools

D. believe their income cannot afford children's education

3.Who believes children's brothers and sisters may influence their academic performance?

A．Lareau． B．Greg Duncan．

C．Susan Mayer． D．James．

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

A. Parents' time matters to children's future．

B. School education determines children's future．

C. Family income counts to children's achievements．

D. Less education means more risks for children's success．

Telepathy: Mind-to-mind Contact

Telepathy is the ability to communicate without the use of the five senses (sight, hearing, touch, smell, taste). It’s an instinct (本能) which can be woken up in times of emergency or need. When we feel that something is happening or about to happen by instinct, we’re using resources within the unconscious mind. When the resources of two persons’ unconscious minds link together into the same frequency, we call it Telepathy.

We can either send or receive Telepathy. If you know who is calling before you answer the ringing phone, you are probably a good receiver. If you think of a person and he/she calls you, you are most likely to be better at sending.

You can easily put your abilities to the test. Think of somebody and will him or her to contact you. Be patient. The other person may not be a good receiver, but they should contact you much earlier than would normally be expected. Or whenever the phones rings, but try “feeling” who is contacting you. Don’t guess, but try to feel it with your mind. However, if neither of these work for you, that doesn’t mean that you have no ability of telepathy. As mentioned earlier, telepathy is most likely to turn up in case of emergency.

Telepathy dreams often contain telepathic messages. Two people may both dream of the other and find that their dreams had a clear connection. These people are probably linking to each other’s unconscious mind.

Telepathy & Relationships. The more people spend time together, the more likely they are to be able to link up to the other’s mind, especially when separated. There are two reasons for this. One is that they understand the other’s mind through time spent together; the other is that there is usually a strong desire to communicate. A mother will often sense that her child is in danger. This is due to the child’s eagerly wanting his or her mother, knowing that this person who would always want to be there for them, and the mother’s deep desire to protect her child from harm.

1.Telepathy turns up when we ____.

A. think of a stranger

B. use the five senses together

C. recall things from our memory

D. sense a close friend in danger

2.You’re better at sending than receiving Telepathy if you ____.

A. can tell who knocks at your door

B. can feel your mom is in danger

C. receive a friend’s call as you wish

D. dream of a friend dreaming of you

3.Which is not the way to help people gain Telepathy?

A. Help them have a strong desire to communicate.

B. Separate them all the time.

C. Help them link up their unconscious minds.

D. Let them spend much time together.
