For each of them there are four choices marked A, B, C and D. You should decide on the best choice. 0 Many parents across the country are getting a
2、 DNA sample just in case they need it if the youngster is kidnapped, runs away or suffers a terrible accident. News reports about child kidnapping and television shows such as “ CSI: Crime Scene Investigation“ are helping drive the interest in keeping genetic records that could be used to identify r
3、emains, hair or blood. “Its the CSI mentality: that DNA is going to be the answer to any problem that comes up,“ said Jerry Nance, supervisor of the forensic assistance unit of the nonprofit National Center for Missing and Exploited Children. Missing kids found murdered or those who are never heard
4、from make up only about 2 percent of the 850,000 kids who are reported missing every year, he said. Most children are found within several days or come home on their own. Despite those numbers, boxes are available that include a photo, fingerprints, a collection swab and a special envelope in which
5、to put the DNA sample. The boxes are distributed by private companies, police stations, orthodontists and others. Most cost from $ 5 to $ 60, Nance said, but some are provided for free. Brian Wagner, police chief in Pleasant Prairie, Wis. , said his department created about 1,000 DNA collection boxe
6、s and began offering them for free in September. Parents have picked up more than 300. “ Weve been doing a lot of child fingerprinting, but thats not always a reliable means of identification,“ Wagner said. Joe Polski, chief operations officer for the International Association for Identification, sa
7、id he would not use the boxes but he would not discourage them. “The chances are so slim that its questionable in my mind if its worth the work to have it,“ he said. Craig Webre, first vice president of the National Sheriffs Association, said DNA collection could become standard within the next deca
8、de. He backs a new program called Kid ID, started by Bob Chastant, a dentist in New Iberia, La, who has collected DNA from kids since 1994 in his practice. He also encouraged dentists nationwide to join the program, in which the dentist takes a digital photograph of the child along with fingerprints
9、. The items are entered into a Kid ID database. “ It allows law enforcement to use the DNA for tracking where the child has been,“ Chastant said. Ed Smart said he wishes he would have known about the DNA boxes before his daughter Elizabeth was kidnapped from her Utah bedroom in June 2002. She was fo
10、und alive nine months later. He said investigators took boxes of her belongings to find her DNA and did not get a sample back for weeks. Having the sample ready could have narrowed down suspects faster.“ It is kind of like an insurance policy you hope you never use,“ he said. 1 According to Jerry Na

14、is daughters belongs earlier. （ C） DNA identification procedure was quicker. （ D） He did not have a DNA box containing his daughters DNA sample before. 5 What is the authors attitude towards the DNA collection boxes? （ A） Negative. （ B） Objective. （ C） Supportive. （ D） Subjective. 5 A report issued
15、last week by the federal governments National Center for Health Statistics contained a jaw-dropper: the parents of nearly one of every five boys in the United States were concerned enough about what they saw as their sons emotional or behavioral problems that they consulted a doctor or a health-care
16、 professional. By comparison, about one out of 10 parents of girls reported these kinds of problems. The report confirms what many of us have been observing for some time now: that lots of school-age boys are struggling. And, parents are intensely worried about them. What is bothering our sons? Some
17、 experts suggest we are witnessing an epidemic of ADHD and say boys need more medication. Others say that environmental pollutants found in plastics, among other things, may be eroding their attention spans and their ability to regulate their emotions. Those experts may be right but I have another s
18、uggestion. Lets examine the way our child rearing and our schools have evolved in the last 10 years. Then ask ourselves this challenging question: could some of those changes we have embraced in our families, our communities and our schools be driving our sons crazy? Instead of unstructured free pla
19、y, parents now schedule their kids time from dawn till dusk. By age 4, an ever-increasing number of children are enrolled in preschool. There, instead of learning to get along with other kids, hold a crayon(蜡笔 )and play Duck, Duck, Goose, children barely out of diapers(尿布 )are asked to fill out work
20、 sheets, learn computation or study Mandarin. The drumbeat for early academics gets even louder when they enter “real“ school. Veteran teachers will tell you that first graders are now routinely expected to master a curriculum that, only 15 years ago, would have been considered appropriate for secon
21、d, even third graders. The way we teach children has changed, too. In many communities, elementary schools have become test-prep factories where standardized testing begins in kindergarten and “teaching to the test“ is considered a virtue. At the same time, recess is being pushed aside in order to p
22、rovide extra time for reading and math drills. So is history and opportunities for hands-on activities like science labs and art. Active play is increasingly frowned on some schools have even banned recess and tag. Some researchers responded to last weeks study by calling for more resources for more
23、 mental-health services for children especially males. Thats an admirable goal. But when nearly one in five boys has such serious behavioral and emotional issues that their parents are talking it over with their pediatrician(小儿科医生 ), you can bet we are facing a problem that requires a more fundament
24、al change in our society than medication or weekly therapy. Lets take a moment, before the school year gets any farther underway, and ask ourselves whether we are raising and educating our boys in a way that respects their natural development. And if we are not, lets figure out how we can bring our
25、family life and our schools back into line. 6 What issue surprised people a lot last week according to the passage? （ A） A report showed that parental worries are escalating. （ B） A report suggested more attention should be paid to boys. （ C） A report said lots of boys have problems and cause intens
26、e worry. （ D） A report issued girls have the same problem with boys. 7 According to the author, school-age boys are struggling because_. （ A） an epidemic of ADHD is prevalent among boys （ B） boys need more medication and mental-health services （ C） boys have too much exposure to environmental pollut
27、ants （ D） families and schools put too much pressure on boys 8 What might boys usually do at school say 15 years ago? （ A） By age 4 they learned to get along with other kids. （ B） By age 4 they learned computation or studied Mandarin. （ C） They took the rest time to do reading and math exercises. （
28、D） They took the rest time to learn history, science labs and art. 9 How to solve so many boys behavioral and emotional issues according to the author? （ A） Call for more resources for more mental-health services for boys. （ B） Change the raising and educating way of boys to respect their nature. （
29、C） Make parents chances to communicate with their childrens pediatrician regularly. （ D） Let the boys grow up in anyway they want without the control of parents. 10 The author writes the passage with a feeling of_. （ A） optimism （ B） irony （ C） anxiety （ D） indifference 10 Competition for admission
30、to the countrys top private schools has always been tough, but this year Elisabeth Krents realized it had reached a new level. Her wake-up call came when a man called the Dalton School in Manhattan, where Krents is admissions director, and inquired about the age limit for their kindergarten program.
31、 After providing the information (they dont use an age limit), she asked about the age of his child. The man paused for an uncomfortably long time before answering. “Well, we dont have a child yet,“ he told Krents. “Were trying to figure out when to conceive a child so the birthday is not a problem.
32、“ School obsession is spreading from Manhattan to the rest of the country. Precise current data on private schools are unavailable, but interviews with representatives of independent and religious schools all told the same story: a glut of applicants, higher rejection rates. Public-opinion poll afte
33、r poll indicates that Americans No. 1 concern is education. Now that the long economic boom has given parents more disposable income, many are turning to private schools, even at price tags of well over $ 10, 000 a year. “Were getting applicants from a broader area, geographically, than we ever have
34、 in the past, “ said Betsy Haugh of the Latin School of Chicago, which experienced a 20 percent increase in applications this year. The problem for the applicants is that while demand has increased, supply has not. “Every year, there are a few children who do not find places, but this year, for the
35、first time that I know of, there are a significant number of children who dont have places, “ said Krents, who also heads a private-school admissions group in New York. So what can parents do to give their 4-year-old an edge? Schools know there is no effective way to pick a class when children are s
36、o young. Many schools give preference to siblings, or alumnis children. Some use lotteries. But most rely on a mix of subjective and objective measures: tests that best identify developmental maturity and cognitive potential, interviews with parents and observation of applicants in classroom setting
37、s. They also want a diverse mix. Children may end up on a waiting list simply because their birthdays fall at the wrong time of year, or because too many applicants were boys. The worst thing a parent can do is to pressure preschoolers to perform for example , by pushing them to read or do math exer
38、cises before theyre ready. Instead, the experts say, parents should take a breath and look for alternatives. Another year in preschool may be all thats needed. Parents, meanwhile, may need a more open mind about relatively unknown private schools or about magnet schools in the public system. Theres
39、no sign of the private-school boom letting up. Daltons spring tours, for early birds interested in the 2009 -2010 school year, are filled. The wait list? Forget it. Thats closed, too. 11 The author cites the example of a man calling for an inquiry to show that_. （ A） childrens birthday really matter
40、s when they apply for private schools （ B） American parents are ignorant of kindergarten program （ C） kindergarten program should set an age limit to keep out unqualified kids （ D） the preschoolers are faced with an incredibly fierce competition in applying for private schools 12 What can be inferre
41、d from the passage? （ A） The high concern of education leads to the increase of applicants for private schools. （ B） Higher rejection rates result from a higher demand and unchanged supply. （ C） A large number of students dont have places in private schools only because many schools give preference
42、to siblings. （ D） Most parents think private schools are better than religious schools. 13 The main idea expressed in the fourth paragraph is_. （ A） what parents should do to make their young children outstanding （ B） how private school choose young children to form a class （ C） why children end up
43、on a waiting list （ D） how difficult it is to get enrolled in private schools 14 When the author says “ another year in preschool may be all thats needed“(Lines 3-4, Para. 5), he implies that the parents should _ （ A） relax and reconsider the situation （ B） take the occasion when the private schools
44、 may not be full the next year （ C） wait until the children are mature enough to go to school （ D） let the children develop all-round abilities 15 The phrase “let up“(Line 6, Para. 5)probably means_. （ A） stop （ B） increase （ C） stay steady （ D） go on 15 Twelve years ago, as a first-year language-ar
45、ts teacher at a middle school in Houston, I had 50 minutes a day with each of my classes. That might sound like a decent amount of time, but after taking roll and checking homework, I was lucky to have even 40 minutes left to teach my students, the majority of whom were low income or just learning t
46、o speak English. I had to take a triage(分类 )approach one thats familiar to most public-school teachers. I focused on the basics of reading and writing to prepare them for the state assessment test, and I was barely able to devote any time to analytical writing, lis-tening comprehension, or persuasiv
47、e speaking. It felt as if I was shortchanging the students, and my frustration was compounded by the fact that after summer vacation they forgot much of what theyd learned, coming back even less prepared than they were three months earlier. Six years ago I founded KIPP Heartwood Academy, a public ch
48、arter school in San Jose, part of a network of 99 KIPP schools nationwide. KIPP(Knowledge Is Power Program)students spend more than 50 percent more time learning, with a school day that typically goes from 7: 30 a. m. to 5 p. m., along with a mandatory three-week summer-school program. The added tim
49、e is getting results. With a student population thats more than 85 percent low income, Heartwood has ranked in the top 10 percent of all California public schools every year since its inception, and it was named a Blue Ribbon School this year by the U. S. Department of Education. The idea of extending the school day and year is gaining momentum. President Obama recently joined other political and academic leaders who are calling for a new look at our outdated custom of halting instruction in J
