Two recent studies have found that punishment is not the best way to influence behavior．
One showed that adults are much more cooperative if they work in a system based on rewards. Researchers at Harvard University in the United States and the Stockholm School of Economics in Sweden did the study.
They had about two hundred college students play a version of the game known as the Prisoner’ s Dilemma. The game is based on the tension between the interests of an individual and a group. The students played in groups of four. Each player could win points for the group, so they would all gain equally. But each player could also reward or punish each of the other three players. Harvard researcher David Rand says the most successful behavior proved to be cooperation. The groups that rewarded it the most earned about twice as much in the game as the groups that rewarded it the least. And the more a group punished itself, the lower its earnings. The study appeared last month in the journal Science.
The other study involved children. It was presented last month in California at a conference on violence and abuse. Researchers used intelligence tests given to two groups. More than eight hundred children were aged two to four the first time they were tested. More than seven hundred children were aged five to nine. The two groups were retested four years later, and the study compared the results with the first test. Both groups contained children whose parents used physical punishment and children whose parents did not.
The study says the IQs of the younger children who were not spanked were five points higher than those who were. In the older group, the difference was almost three points. The more they are spanked, the slower their mental development.
According to the first study, we mainly infer that .
| A．the game is called Prisoner’s Dilemma |
| B．the less a group punished itself, the lower its earnings |
| C．adults are much more cooperative if rewarded |
| D．the game is introduced in the journal Science |
Which of the following is TRUE according to the second study?
| A．Children's IQs have much to do with physical punishment． |
| B．The study is about violence and cooperation of children． |
| C．The children tested were divided into groups of four． |
| D．Children's mental development only relies on their IQs． |
What does the underlined word "spanked" refer to?
| A．Punished． | B．Blamed． | C．Tested． | D．Praised． |
What might be the best title for the text?
| A．The Best Way to Correct Misbehavior |
| B．Punishment Is the Best Way of Education |
| C．Cooperation Is the Most Successful Behavior |
| D．Punishment or Reward: Which Works Better on Behavior? |

_____ Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case.
The ridge （隆起） structure on a person's fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one, which bears a reproduction of the original pattern. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take.
Finger-prints can be made very easily with printer's ink. They can be recorded easily.
______ Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. ___
___ .
When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. ______ . Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.
| A．Special techniques are used to "develop" them. |
| B．A fingerprint is an impression of the friction ridges of all part of the finger. |
| C．It is only when the inner skin is injured that the arrangement will be destroyed. |
| D．With special methods, identification can be achieved successfully within a short time. |
E. A latent(隐约的)print is the chance reproduction of the friction ridges deposited on the surface of an item.
F. His finger-prints can prove who he is even if his appearance has been changed by age or accident.
G. Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable.
Throughout this long, tense election, everyone has focused on the presidential candidates and how they’ll change America. Rightly so, but selfishly, I’m more fascinated by Michelle Obama and what she might be able to do, not just for this country, but for me as an African-American woman. As the potential First Lady, she would have the world’s attention. And that means that for the first time people will have a chance to get up close and personal with the type of African-American woman they so rarely see.
Usually, the lives of black women go largely unexamined. The prevailing(普通的)theory seems to be that we’re all hot-tempered single mothers who can’t keep a man. Even in the world of make-believe, black women still can’t escape the stereotype(陈规)of being eye-rolling, oversexed females raised by our never-married, alcoholic mothers.
These images have helped define the way all women are viewed, including Michelle Obama. Before she ever gets the chance to commit to a cause, charity or foundation as First Lady, her most urgent and perhaps most complicated duty may be simple to be herself.
It won’t be easy. Because few mainstream publications have done in-depth features on regular African-American women, little is known about who we are, what we think and what we face on a regular basis. For better or worse, Michelle will represent us all.
Just as she will have her critics, she will also have millions of fans who usually have little interest in the First Lady. Many African-American blogs have written about what they’d like to see Michelle bring to the White House—mainly showing the world that a black woman can support her man and raise a strong black family. Michelle will have to work to please everyone—an impossible task. But for many African-American women like me, just a little of her poise (沉着), confidence and intelligence will go a long way in changing an image that’s been around for far too long. Why does Michelle Obama hold a strong fascination for the author?
| A．She serves as a role model for African women. |
| B．She possesses many admirable qualities becoming a First Lady. |
| C．She will present to the world a new image of African-American women. |
| D．She will pay closer attention to the interests of African-American women. |
What is the common stereotype of African-American women according to the author?
| A．They are victims of violence. | B．They are of an inferior violence. |
| C．They use quite a lot of body language. | D．They live on charity and social welfare. |
What do many African-Americans write about in their blogs?
| A．Whether Michelle can live up to the high expectations of her fans. |
| B．How Michelle should behave as a public figure. |
| C．How proud they are to have a black woman in the White House. |
| D．What Michelle should do as wife and mother in the White House. |
What do many African-American women hope Michelle Obama will do?
| A．Help change the prevailing view about black women. |
| B．Help her husband in the task of changing America. |
| C．Outshine previous First Lady. |
| D．Fully display her fine qualities. |
There are hundreds of things that your parents controlled for you when you were a child. And it’s a good thing, too — kids need this kind of protection and assistance, because they aren’t mature enough to take care of themselves and make careful decisions on their own.
But eventually, kids grow up and become teens. It’s totally normal for teens to create their own opinions, thoughts, and values about life; it’s what prepares them for adulthood. But as you change and grow into this new person who makes his or her own decisions, your parents may have a difficult time adjusting themselves to it.
In most families, it’s this adjustment that can cause a lot of fighting between teens and parents. Teens get angry because they feel parents don’t respect them and aren’t giving them space to do what they like, and parents get angry because they aren’t used to not being in control or they disagree with the teens’ decisions.
It’s easy for feelings to get very hurt when there are conflicts like these. And more complicated issues can cause even bigger arguments, because your parents will always be intent on protecting you and keeping you safe, no matter how old you are.
The good news about fighting with your parents is that in many families the arguing will lessen as parents get more comfortable with the idea that their teens have a right to certain opinions. It can take several years for parents and teens to adjust to their new roles, though. In the meantime, concentrate on communicating with your parents as best you can.
Sometimes this can feel impossible — like they just don’t see your point of view and never will. But talking and expressing your opinions can help you gain more respect from your parents, and you may be able to reach a compromise that makes everyone happy. Keep in mind, too, that your parents were teens once and that in most cases, they can relate to what you’re going through.Why do parents always want to control their children?
| A．They are afraid to lose their children. |
| B．They want to protect their children. |
| C．They don’t believe the ability of their children. |
| D．They can’t accept their children are growing. |
What does the underlined word “lessen” in Paragraph 5 probably mean?
| A．disappear. | B．increase. |
| C．strengthen. | D．decrease. |
The author suggested that teenagers ____.
| A．fight with their parents bravely for their rights |
| B．obey their parents without any doubt |
| C．communicate with their parents actively |
| D．persuade their parents in as many ways as possible |
It can be inferred from the passage that ____.
| A．most parents will give in while fighting with their children |
| B．the conflict between parents and teenagers can be solved |
| C．the only way for teens to get freedom is to leave home |
| D．only few parents do well in facing the growth of their children |
