第1题：
The following statements are true EXCEPT_____.
［A］ divorce is usually caused by more than one reason
［B］ a six-year-old boy may fear being deserted by his parents
［C］ as the kids grow older, they have a better understanding of divorce
［D］ a young girl may feel more shameful on parental divorce than an older boy
正确答案：D本题考查推理引申。第二段第三句提到，年长孩子对父母离异的羞愧、愤怒及自我反省心理取代了年幼孩子的困惑和恐惧心理。由此可见，年长的孩子更容易感到羞愧。［D］与事实相反。为本题的正确选项。该段第二句提到，长大的孩子更能意识到父母离异的决定不能简单归结于任何单一的原因。因此［C］正确，［A］是该句中提到的事实。第三句提到，8岁以后孩子对被抛弃的恐惧才会减少，因此可推出［B］符合事实。

第2题：
Children in the United States are exposed to many influences other than that of their families. Television is the most significant of these influences, because the habit of watching television usually begins before children start attending school.
Parents are concerned about the lack of quality in television programs for children. The degree of violence in many of these shows also worries them. Studies indicate that, when children are exposed to violence, they may become aggressive or insecure.
Parents are also concerned about the commercials (商业广告) that their children see on television. Many parents would like to see fewer commercials during programs for children. And some parents feel that these shows should not have any commercials at all because young minds are not mature enough to deal with the claims made by advertisers.
Educational television has no commercials and has programs for children that many parents approve of. The most famous of these is Sesame Street, which tries to give preschool children a head start in learning the alphabet (字母) and numbers. It also tries to teach children useful things about the world in which they live.
Even though most parents and educators give Sesame Street and shows like it high marks for quality, some critics argue that all television, whether educational or not, is harmful to children. These critics feel that the habit of watching hours of television every day turns children into bored and passive (被动的) consumers of their world rather than encouraging them to become active explorers of it
1). Which of the following statements is not based on the passage?
A. Parents are worried about the influence from television on their children.
B. Television has much influence on children.
C. Both parents and their children like watching educational television.
D. Some critics think that television is no good for children.
2). In what ways do children suffer from television?
A. They become the victims of social violence.
B. They spend hours watching television instead of doing school work.
C. The programs make the children lose interest in the world.
D. The programs make the children spend too much of their parents’ money.
3). Parents would not like their children to see commercials because ______
A. they think that their children are not old enough to handle advertising
B. commercials teach children alphabet and numbers
C. commercials help to sell products
D. they don’t like commercials
4). Educational television is widely appreciated because _____
A. it does have the same commercials as others
B. it offers programs for both children and their parents
C. many parents like the programs it offers for their children
D. children can learn some school subjects before they go to school
5). Which of the following can best serve as the title of the passage?
A. Watching Too Much Television Is Harmful to Young Minds.
B. Television Is More Harmful than Educational.
C. Television’s Influence on Children.
D. More Education Television.

Child maltreatment is a global problem with serious life long consequences.There are no reliable global estimates for the prevalence of child maltreatment. Data for many countries,especially low and middle income countries,are lacking.
Child maltreatment is complex and difficult to study. Current estimates vary widely depending on the country and the method of research used.Nonetheless,international studies reveal that approximately 20% of women and 5%一10% of men report being sexually abused as children.While 25%一50%of all children report being physically abused. Additionally,many children are subject to emotional abuse(sometimes referred to as psychological abuse).
Every year,there are an estimated 31 ,000 homicide（他杀）deaths in children under 15. This number underestimates the true extent of the problem,as a significant proportion of deaths due to child maltreatment are incorrectly attributed to（归因于）falls, burns and drowning.
Child maltreatment causes suffering to children and families and can have long-term consequences.Maltreatment causes stress that is associated with disruption in early brain development. Extreme stress can impair the development of the nervous and immune systems.Consequently,as adults,maltreated children are at increased risk for behavioural,physical and mental health problems.Via the behavioural and mental health consequences,maltreatment can contribute to heart disease,cancer,suicide and sexually transmitted infections.
Beyond the health consequences of child maltreatment,there is an economic impact,including :ost of hospitalization,mental health treatment,child welfare,and longer-term health cost.
A number of risk factor for child maltreatment has been identified.These risk factors are not present in all social and cultural contexts,but provide an overview when attempting to understand the causes of child maltreatment.
It is important to emphasize that children are the victims and are never to blame（责怪）for maltreatment.A number of characteristics of an individual child may increase the likelihood of being maltreated,such as being either under four years old or an adolescent,being unwanted,or failing to fulfill the expectations of parents and having special need,crying persistently or having abnormal physical features.The maltreated children often bear all the following characteristics except________according to the passage.
A:they frequently and easily cry
B:they are in infant's or in adolescent period
C:they are often neglected by their parents or friends
D:they often try their best to meet the requirements from their parents答案：D解析：文中第一段提到了虐待儿童是一个全球性问题，无法获得中低收入国家中儿童受虐数字资料；第二段开头提到了儿童受虐数字难以统计的另外一个原因，即研究方法的差异性。只有专业统计人员是否缺乏没有提及，因此答案为C。
文中第二段对数字有明确说明。
文中第三段指出每年巧岁以下儿童死亡人数大概在31 000人。该数字大大低估了实际情况，因为有相当多的由于受虐而致死的儿童被归因为摔死、烧死、淹死。文中没有明确指出腹泻，因此可推断出该题答案为B。
文中提到虐待儿童会导致其身体发育出现问题，包括神经系统、免疫系统、大脑发育，以及成年后会出现的疾病，但都没有提到是否会对其记忆力产生影响。因此，答案为A。
最后一段说，有几大特征会增加儿童受虐待的可能性，例如，4岁以下或者不受欢迎、不能满足父母的期望、有特殊需求、不停哭闹或是身体有异常的青少年。 -

第8题：
"SeasameStreet"has been called"the longest street in the world".
This is because the television program by that name can now be seen in so many parts ofthe world.
The program,which went on the air in New York in 1969,uses songs,jokes,andpictures to give children a basic understanding of numbers,letters and humanrelationships.More than 6 million children in the United States watch itregularly.The viewers(观众)include more than half the nation′s children before school age.
Manyteacher consider the program a great help,though some teachers find that problems happen when the first-year pupils who have learned from"SeasameStreet"are in the same class with those who have not watched the program.Tests have shown that children who watch it five times a week learn more than those who seldom watch it.In the United States the program is shown at differenthours during the week in order to increase the number of children who can watchit regularly.
Why has"Seasame Street"been so much more successful than other children′sshows?Many reasons have been suggested.Perhaps one reason is that motherswatch"Seasame Street"along with their children.But the best reasonfor the success of the program may be that it makes every child watching itfeel able to learn.The child finds himself learning,and he wants to learnmore.
"Seasame Street"is a TV program produced mainly forA.children
B.children of school age
C.primary school teachers and pupils
D.mothers and their children答案：A解析：考情点拨:事实细节题

单选题Passage1Children who spend more than two hours a day at a computer or watching television are more likely than others to have mental problems，scientists say.Researchers found that 11-year-olds who spent several hours in front of a screen each day did worse on mental health tests，no matter how much physical exercise they got. The University of Bristol study，published in Pediatrics，involved more than 1，000 children aged about 10.They also had the kids fill out questionnaires designed to gauge the kids' emotional well-being and behavior.The questionnaires contained 20 questions covering five sections-emotional difficulties，conduct problems，hyperactivity or inattention，friendships and peer groups and problems relating to friends and peer groups.The study found no direct evidence that sitting in front of a screen actually causes mental health problems. Instead，it suggests that children with difficulties，such as extreme shyness，are more likely to choose TV or computer games than sociable activities. In the study，children were asked whether they agreed，disagreed or somewhat agree with a list of statements，including，I generally play alone or keep to myself and，I am often unhappy or tearful.They were also asked how much exercise they took and how long they spent at a TV or computer screen.According to the study，children who spent more than two hours a day at a screen had a 60% higher risk of mental problems than children who spent fewer viewing hours. The risk was only slightly higher in children who did little or no exercise.Physical activity is good for health in many ways，but it can't make up for long hours of screen viewing. Parents should consider limiting their children's screen viewing to no more than 2 hours a day，”said the study organizer，Angie Page.Previous studies have raised concerns that watching too much television can affect children's behavior in later life. A Canadian study found that those who watched most TV as young children performed worse at school, ate more junk food and had more trouble concentrating.What information can we get about the University of Bristol study?AThe results of it have been published.

Cities alarmed by deaths and injuries of pedestrians are taking efforts to make crosswalks safer for people on foot, especially seniors and children who need more time to cross streets.
A pedestrian is killed in a traffic accident in the USA every 110 minutes；one is injured every nine minutes, according to official date. Crosswalk can be especially dangerous for the elderly. Among people 70 and older, 36% of pedestrian deaths in 2006 occurred in crosswalks, compared with 21% of those younger than 70 , according to the Insurance Institute for Highway Safety.
The Federal Highway Administration（FHWA）advises that next year states increase by nearly 15% the amount of time traffic lights provide for pedestrians to cross the street after the flashing orange hand appears .
FHWA spokesman Doug Hecox says reasons for the change include an aging population that needs more time to cross, health-conscious Americans walking more, children encouraged to walk to prevent getting overweight and high gas prices pushing people to walk instead of drive.
Pedestrian deaths went down by 12% from 5,449 in 1996 to 4,784 in 2006. But among those in 2006, 471 were killed in crosswalks, down slightly from 488 ten years earlier, the National Highway Traffic Safety Administration (NHTSA) says.
53. Which of the following is true according to the text?
A. Among 100 pedestrian deaths there were 21 people younger than 70.
B. Old people are more likely to meet with accidents in crosswalks.
C. Traffic accidents killed more old people than young people.
D. About seven traffic accidents happened per hour.
正确答案：B

阅读下面的句子，根据文章内容进行判断，正确写“T”错误写“F”。
The law defines youthful offenders (aged 18 or under) as offenses. As for the same offenses, the court would consider an adult as a offenders" are juveniles who commit offenses appropriate only to juveniles, such as truancy from school. Here are a few ideas to help prevent your children from being a delinquent.
Keep your children in school to help prevent delinquency. Minor offenses, such as truancy, can lead to more serious offenses. Make clear to your children your expectations about their school attendance. Meet with school officials if necessary.
Exercise adequate supervision. Juveniles rarely commit serious offenses while under the supervision of an adult. Seek the assistance of your local service agencies, if you feel you cannot control your children. Attend parenting classes, or join a local support group if you are having trouble understanding how to exercise discipline.
Educate your children about the dangers of drugs. Drug offenses and addiction can have serious consequences for your children. Let your children know you will not tolerate drug use. Stay informed about drug use trends in children.
Get your children involved in after-school recreational activities, sports, community service or other positive activities. Young people with positive outlets for their energy are more likely to do well in school and avoid the problems of delinquency.
Know who your children’s friends are. Show an interest in your children's social life and peer groups. Peer pressure may have a bad effect on teenagers and young people. Do not allow your children to associate with juvenile delinquents.
( )21.the court would consider youthful offenders as”criminals” if they commit offenses.

Generation Gap A few years ago,it was fashionable to speak of a generation gap,a division between young people and their elders.Parents complained that children did not show them proper respect and obedience,while children complained that their parents did not understand them at all.
What had gone wrong?Why had the generation gap suddenly appeared?Actually,the generation gap has been around for a long time.Many critics argue that it is built into the fabric of our society.
One important cause of the generation gap is the opportunity that young people have to choose their own life styles.In more traditional societies,when children grow up,they are expected to live in the same area as their parents,to marry people that their parents know and approve of, and often to continue the family occupation.
In our society,young people often travel great distances for their education,most out of the family home at an early age,marry or live or choose occupations different from those of their parents. In our upwardly mobile society,parents often expect their children to do better than they did:to find better jobs,to make more money,and to do all the things that they were unable to do.
Often,however,the ambitions that parents have for their children are another cause of the division between them.Often they dis-cover that they have very little in common with each other. Finally,the speed at which changes take place in our society is another cause of thie gap between the generations.In a traditional culture,elderly people are valued for their wisdom,but in our society the knowledge of a lifetime may become obsolete overnight.
The young and the old seem to live in two very different worlds,separated by different skills and abilities, No doubt,the generation gap will continue to be a feature of American life for some time to come.Its causes are rooted in the freedoms and opportunities of our society,and in the rapid pace at which society changes.Which of the following statements is TRUE according to the passage?
A:Parents should be more tolerable towards their children.
B:The young generation should value the older generation for their wisdom.
C:The generation gap is partly created by the older generation.
D:The generation gap should be avoidable in American society.答案：C解析：文章第一段主要讲述了美国社会中所存在的代沟问题：父母抱怨孩子们不够尊敬和服从他们；孩子们抱怨父母不理解他们。实际上，该问题已经存在了很长一段时间。评论家认为代沟已经成为美国社会结构的一部分。由此可见，代沟是美国的一种特征。因此B为正确答案。
由文章第一段倒数第二句话可知，代沟问题已经存在了很长时间。around在此处意思是“存在”，与in existence（存在）意思相近。因此D为正确答案。
文章从三方面讲述了代沟形成的原因。由第二段第一句话可知，形成代沟的一个重要原因是年轻人必须选择自己的生活方式；由第三段第一句话可知，父母对孩子期望过高也是代沟形成的一个原因；由第四段第一句话可知，社会的快速变化也是导致代沟形成的原因。而文中并未提到现代教育使得孩子与父母想法不同的问题。因此D为正确答案。
由文章第三段最后一句话可知，父母和孩子会发现彼此之间几乎没有相似之处。因此D为正确答案。
文章主要讲的是美国社会中所存在的代沟问题及其形成的原因，并没有提到如何解决这一问题，因此排除A.B选项；而D项（美国社会应该避免代沟问题）文中也未提及.由文章第三段可知，父母对孩子期望过高也是形成代沟的原因。因此C为正确答案。 -

The University of Bristol study，published in Pediatrics，involved more than 1，000 children aged about 10.They also had the kids fill out questionnaires designed to gauge the kids' emotional well-being and behavior.The questionnaires contained 20 questions covering five sections-emotional difficulties，conduct problems，hyperactivity or inattention，friendships and peer groups and problems relating to friends and peer groups.The study found no direct evidence that sitting in front of a screen actually causes mental health problems. Instead，it suggests that children with difficulties，such as extreme shyness，are more likely to choose TV or computer games than sociable activities. In the study，children were asked whether they agreed，disagreed or somewhat agree with a list of statements，including，"I generally play alone or keep to myself" and，"I am often unhappy or tearful".They were also asked how much exercise they took and how long they spent at a TV or computer screen.According to the study，children who spent more than two hours a day at a screen had a 60% higher risk of mental problems than children who spent fewer viewing hours. The risk was only slightly higher in children who did little or no exercise."Physical activity is good for health in many ways，but it can't make up for long hours of screen viewing. Parents should consider limiting their children's screen viewing to no more than 2 hours a day，”said the study organizer，Angie Page.Previous studies have raised concerns that watching too much television can affect children's behavior in later life. A Canadian study found that those who watched most TV as young children performed worse at school, ate more junk food and had more trouble concentrating.Which of the children behavior below leads to the highest risk of the mental problems, according to the University of Bristol study?APlaying computer every day.
BWatching TV 3 hours per day.
CDoing few physical activities.
