Many theories regarding the causes of juvenile delinquency (crimes committed by young people) focus either on the individual or on society as the major contributing influence. Theories41on the individual suggest that children 42 criminal behavior before they were not sufficiently 43 for previous misbehaviors or that they have learned criminal behavior through interaction with others. Theories focusing on the role of society suggest that children commit crimes in 44 to their failure to rise above their socioeconomic status or as a rejection of middle-class values.
Most theories of juvenile delinquency have focused on children from 45 families, 46 the fact that children from wealthy homes also commit crimes. The latter may commit crimes for lack of adequate control from parents. All 47, however, are uncertain or unimproved and are of course challenged with criticism.
Changes in the social structure may indirectly 48 juvenile crime rates. For example, changes in the economy that 49 to fewer job opportunities for youth and rising unemployment 50 make gainful employment increasingly difficult to obtain. This results in 51 among youths and may in 52 lead more youths into criminal behavior.
Families have also experienced 53 these years. More families consist of one parent households or two working parents; 54 ,children are likely to have less supervision at home than was common in the traditional family 55 . This lack of parental supervision is thought to be an influence on juvenile crime rates. Other noticeable 56 of offensive acts include 57 experience or failure in school, the 58 availability of drugs and alcohol, and the growing phenomenon of child abuse and child neglect. All these conditions tend to increase the 59 of a child committing a criminal act, 60 a direct cause and effect relationship has not yet been established.

A
Chimpanzees, long considered reluctant to share, apparently can display selfless tendencies, revealing one more key way our closest living relatives are like humans, scientists find. These findings could shed light on the evolution of altruism in humans.
Previously, a belief was widely held that human altruism evolved only after humans split from their ape cousins about 6 million years ago. In recent years, however, research has revealed just how much chimpanzees have in common with us. They can hunt with spears, play with dolls and mourn their partners’ death.
"Most of the earlier studies had presented the apes with a complex implement that helped them deliver food to themselves or others, often so complicated that the experiments tested tool skills rather than social
tendencies," De Waal told Live Science. "Ours is the first study that uses no such implement at all."
In addition to using complex food-delivery systems, past experiments often placed the chimpanzees so far apart that they might not have realized how their actions benefited others. In these new, simplified experiments, two apes were housed next to each other with a screen through which they could see each other. Then, one chimpanzee had to choose between two differently colored tokens (币) from a bin, one of which represented a pro-social (亲社会的) option, the other a selfish option. The pro-social option would cause both chimpanzees to receive a piece of banana wrapped in paper. The selfish option only rewarded the ape who made the choice.
In a study with seven adult female chimps placed into various pairs, the scientists found all the apes showed a definite preference for the pro-social option. "For me, the most important finding is that like us, chimpanzees take into account the needs and wishes of others," researcher Victoria Horner, said.
The chimpanzees behaved especially altruistically toward partners who either patiently waited or gently reminded them that they were there by drawing attention to themselves. They were less likely to reward partners who pressured through making a fuss, begging persistently or spitting water at them. This is opposite to a long-standing view that the chimpanzees only share food under pressure.
61. The word " altruism " (paragraph 1) is closest in meaning to ______.
A. selfishness
B. selflessness
C. willingness
D. reluctance
62. Recent re searches are performed with less complicated implements mainly to ______.
A. show that chimps are only good at using implements
B. see whether chimps are willing to share food with others
C. find out if chimps are likely to reward partners
D. test chimps’ social tendencies instead of tool skills
63. Which of the following might be the best title of the passage?
A. Evolution History of Altruism in Humans
B. Similarities between Chimps and Mankind
C. Chimps Do Show Selfless Behavior
D. Chimps Only Share Food under Pressure
B
Energy independence has a nice ring to it. Doesn’t it? I f you think so, you’re not alone, because energy independence has been the dream of American president for decades, and never more so than in the past few years, when the most recent oil price shock has been partly responsible for kicking off the great recession.
“Energy independence” and its rhetorical (修辞的) companion “energy security” are, however, slippery concepts that are rarely though through. What is it we want independence from, exactly?
Most people would probably say that they want to be independent from imported oil. But there are reasons that we buy all that old from elsewhere.
The first reason is that we need it to keep our economy running. Yes, there is a trickle（涓涓细流）of biofuel（生物燃料）available, and more may become available, but most biofuels cause economic waste and environmental destruction.
Second, Americans have basically decided that they don’t really want to produce all their own oil. They value the environmental quality they preserve over their oil imports from abroad. Vast areas of the United States
are off-limits to oil exploration and production in the name of environmental protection. To what extent are Americans really willing to endure the environmental impacts of domestic energy production in order to cut back imports?
Third, there are benefits to trade. It allows for economic efficiency, and when we buy things from places that have lower production costs than we do, we benefit. And although you don’t read about this much, the United States is also a large exporter of oil products, selling about 2 million barrels of petroleum products per day to about 90 countries.
There is no question that the United States imports a great deal of energy and, in fact, relies on that steady flow to maintain its economy. When that flow is interrupted, we feel the pain in short supplies and higher prices. At the same time, we obtain massive economic benefits when we buy the most affordable energy on the world market and when we engage in energy trade around the world.
64. What does the author say about energy independence for America?
A. It sounds very attractive.
B. It ensures national security.
C. It will bring oil prices down
D. It has long been everyone’s dream.
65. Why does America rely heavily on oil imports?
A. It wants to expand its storage of crude oil(原油).
B. Its own oil reserves are quickly running o ut.
C. It wants to keep its own environment undamaged.
D. Its own oil production falls short of demand.
66. What does the author say about oil trade?
A. It proves profitable to both sides.
B. It improves economic
efficiency.
C. It makes for economic prosperity.
D. It saves the cost of oil exploration.
C
The question of whether our government should promote science and technology or the liberal arts(文科) in higher education isn’t an eith er/or proposition(命题)，although the current emphasis on preparing young Americans for STEM（science, technology, engineering, maths）-related fields can make it seem that way.
The latest congressional report acknowledges the critical importance of technical training, but also states firmly that the study of the humanities and social sciences must remain central components of America’s educational system at all levels. Both are critical to producing citizens who can participate effectively in our democratic society, become creative leaders, and benefit from the spiritual enrichment that the reflection on the great ideas of mankind over time provides.
Parents and students who have invested heavily in higher education worry about gradua tes’ job prospects as techn ological advances and changes in domestic and global markets transform professions in ways that reduce wages and cut jobs. Under these circumstances, it’s natural to look for wh at may appear to be the most “practical” way out of the problem “Major in a s ubject designed to get you a job” seems the obvious answer to some, though this ignores the fact that many disciplines in the humanities characterized as “soft” often, in fact, lead to employment and success in the long run. Indeed, according to surveys, employers have expressed a preference for students who have received a broadly-based education that has taught them to write well, think critically, research creatively, and communicate
easily.
Moreover, students should be prepared not just for their first job, but for their 4th and 5th jobs, as there’s little reason to doubt that people entering the workforce today will be called upon to play many different roles over the course of their careers. The ones who will do the best in this new environment will be those whose educations have prepared them to be flexible. The ability to draw upon every available tool and insight—picked up from science, arts, and technology—to solve the problems of the future, and take advantage of the opportunities that present themselves, will be helpful to them and the United States.
67. What does the latest congressional report suggest?
A. STEM-related subjects help students find jobs in the information society.
B. Higher education should be adjusted to the practical needs of society.
C. The liberal arts in higher education help enrich students’ spiritual life.
D. The humanities and STEM subjects should be given equal importance.
68. What kind of job applicants do employers look for?
A. Those who have a strong sense of responsibility.
B. Those who are good at solving practical problems.
C. Those who are likely to become innovative leaders.
D. Those who have received an all-round education.
69. What advice does the author give to college students?
A. Seize opportunities to explore their potential.
B. Try to take a variety of practical courses.
C. Adopt a flexible approach to solving problems.
D. catch as many chances as possible to change their jobs.
D
At the beginning of the World Series of 1947, I experienced a completely new emotion, when the National Anthem was played. This time, I thought, it is being played for me, as much as for anyone else. This is organized major league baseball, and I am standing here with all the others; and everything that takes place includes me.
About a year later, I went to Atlanta, Georgia, to play in an exhibition game. On the field, for the first time in Atlanta, there were Negroes and whites. Other Negroes besides me. And I thought: What I have always believed has come to be.
And what is it that I have always believed? First, that imperfections are human. But that wherever human beings were given room to breathe and time to think, those imperfections would disappear, no matter how slowly. I do not believe that we have found or even approached perfection. That is not necessarily in the scheme of human events. Handicaps, stumbling blocks, prejudices — all of these are imperfect. Yet, they have to be dealt with because they are in the scheme of human events.
Whatever obstacles I found made me fight all the harder. But it would have been impossible for me to fight at all, except that I was sustained by the personal and deep-rooted belief that my fight had a chance. It had a chance because it took place in a free society. Not once was I forced to face and fight an immovable object. Not once was the situation so cast-iron rigid that I had no chance at all. Free minds and human hearts were at work all around me; and so there was the probability of improvement. I look at my children now, and know that I must still prepare them to meet obstacles and prejudices.
But I can tell them, too, that they will never face some of these prejudices because other people have gone before them. And to myself I can say that, because pro gress is unalterable, many of today's dogmas (教条)will
have vanished by the time they grow into adults. I can say to my children: There is a chance for you. No guarantee, but a chance. And this chance has come to be, because there is nothing static with free people. There is no Middle Ages logic so strong that it can stop the human tide from flowing forward. I do not believe that every person, in every walk of life, can succeed in spite of any handicap. That would be perfection. But I do believe — and with every fiber in me — that what I was able to attain came to be because we put behind us (no matter how slowly) the dogmas of the past: to discover the truth of today; and perhaps find the greatness of tomorrow.
I believe in the human race. I believe in the warm heart. I believe in man's honesty. I believe in the goodness of a free society. And I believe that the society can remain good only as long as we are willing to fight for it — and to fight against whatever imperfections may exist. My fight was against the barriers that kept Negroes out of baseball. This was the area where I found imperfection, and where I was best able to fight. And I fought because I knew it was not doomed to be a losing fight. It couldn't be a losing fight-not when it took place in a free society. And in the largest sense, I believe that what I did was done for me —that it was my faith in God that sustained me in my fight. And that what was done for me must and will be done for others.
70. Why did the author say he had experienced a completely new emotion?
A. Because he won game.
B. Because he was an American.
C. Because he could compete in the game and won the game.
D. Because the National Game was played for him.
71. From the passage, we know that the author is ___________.
A. an African.
B. a Chinese
C. a white man
D. a black man
72. The author firmly believed that____________.
A. humans are imperfect if they all unite together to overcome the difficulties.
B. humans needn’t approach perfect even if they can.
C. humans should face the obstacles and fight for it bravely.
D. humans are becoming kind and honest if they have freedom.
73. We can infer from the passage that_________.
A. the fight between Negroes and Whites never ends
B. the civil war broke out because the Negroes fought for their freedom
C. In the past Negroes were kept out of baseball.
D. the fight ended up with a game.
74. The underlined word ‘vanished’ most probably means __________
A. disappear
B. increase
C. appear
D. happen
75. The best title of this passage may be_________.
A. Nothing matters except fighting
B. Success lies in hard work
C. freedom is everything
D. Free Minds and Hearts makes a difference

Research shows that the summer before college can be a dangerous time for teenagers, as they are between home and high school on the one side, and a more challenging and independent existence as a college student on the other.
Take drinking for example. Research has reported that teenagers tend to increase their alcohol use during the summer before college and i n their first term. Such drinking can lead to tragedy: it’s estimated that more than 1,100
college students at 18 to 24 years of age die each year from alcohol-related injuries, including car crashes, and almost 600, 000 are injured under the influence of alcohol.
In addition to drinking, future freshmen may also have gaps in their knowledge about other aspects of university life. A study has found that students are “generally aware” of the fact that they have to place them into college courses and the ir school’s curricular requirements. In addition, many students hold misunderstandings such as “Getting into college is the hardest part”, and “I can take whatever classes I want when I get to college”. In fact, students’courses may be determined by their level of preparation. It is found that college-bound high-school graduates are faced with a number of potentially frightening tasks during the summer. For example, colleges typically require students to take placement tests(分班考试)and fill out a lot of paperwork, including housing and medical forms, over the summer. Completing these tasks may be especially frightening for low-income and first-generation college-bound students whose families may be short of experience with the college-going process.
In addition, it’s only in the summer after high-school graduation when students face the reality of paying the first college bill, which often includes unexpected costs like required health insurance. For college-intending students, successfully controlling the post-high-school summer thus requires a level of finance that may be unrelated to their ability to succeed in the classroom. As a result, students who have already broken through many barriers to college admission may fail to enter college. Paring college-bound students with “fellow advisers”---students already in college who have been trained to support and coach their learners through the summer---improves the rate at which the learners show up at college. Even
more wonderful, a low-cost campaign of text messages---in which researchers sent recent high-school graduates and their parents a series of eight to ten text-message reminders of key tasks to complete over the summer---is just as effective in increasing the rate of students who successfully make the change to college.
A little “summer pushing ” could be a key step in getting students all the way across the finish line. The Key to College Success: Summer

一、第三章 相互作用——力易错题培优（难） 1．如图所示，竖直面内有一圆环，轻绳OA 的一端O 固定在此圆环的圆心，另一端A 拴一球，轻绳AB 的一端拴球，另一端固定在圆环上的B 点。最初，两绳均被拉直，夹角为θ（2 π θ> ）且OA 水平。现将圆环绕圆心O 顺时针缓慢转过90°的过程中（夹角θ始终不 变），以下说法正确的是（ ） A ．OA 上的张力逐渐增大 B ．OA 上的张力先增大后减小 C ．AB 上的张力逐渐增大 D ．AB 上的张力先增大后减小 【答案】B 【解析】 【分析】 【详解】 取球为研究对象，缓慢转动过程可视为平衡状态，物体受到重力mg ，OA 绳子的拉力 OA F ，AB 绳子的拉力AB F ，这三个力合力为零，可构成如图所示的矢量三角形，由动态图 分析可知OA F 先增大后减小，AB F 一直减小到零。 故选择B 。 2．如图，一固定的粗糙水平横杆上套有a 、b 两个轻环，系在两环上的两根等长细绳拴住一重物处于静止状态，现将两环距离适当变小后重物仍处于静止状态，则（ ） A ．两绳对重物的合力变大 B ．细绳对重物的拉力变小
C ．杆对a 环的支持力变大 D ．b 环对杆的摩擦力变大 【答案】B 【解析】 【分析】 【详解】 A ．根据平衡条件可知，两绳对重物的合力大小始终等于物体的重力大小，所以合力不变，A 错误； B ．对重物受力分析，如图所示 根据平衡条件，分析可得 2cos 2 A B mg F F α== 当两环间距离变小后，α变小，则拉力F A 、F B 均变小，B 正确； C ．以两个轻环和钩码组成的系统为研究对象，设系统总质量为M ，横梁对铁环的支持力F N ，分析如下图所示 根据平衡条件可得 N 2F Mg = 即N 1 2 F Mg = ，可见水平横梁对环的支持力F N 不变，C 错误； D ．以b 侧环为研究对象，受力分析如下图

高三年级安全工作计划 篇一：高三年级工作计划 东台市安丰中学 XX-XX学年度高三年级组工作计划 为进一步提高我校高三年级的教学效益，增强各项工作的针对性，力争XX年高考取得成功，学校在总结前几届高三复习经验的基础上，针对本届学生实际，特制定高三管理方案： 一、情况介绍 本届高三共有17个教学班，其中物化组合5个班，物生组合7个班，政史组合2个班，史地组合3个班，在班学生885人（其中借复读生164人），应届生721人，加上在东中借读的10人左右，总人数比上一届要少70人左右，这一届学生由于在三仓中学后一批次录取，生源与仓中相差不大，优质生源还略差于三仓中学，中考时全东台前1000名、1500名、XX名，我校分别比仓中少12人、44人、7人；与前几届相比，生源下降明显；加上本届在高一阶段时正值四星级高中验收，学校组织开展了多项活动，造成主要学科课时不足，学生的基础不够扎实，学生的行为习惯养成也没有完全到位，因而高一高二阶段整体的优势不够明显，小高考成绩也未能全面反超三仓中学。尽管在9月份的盐城市高三摸底考试中我校达本二模拟线的465人，比仓中多60人左
右，各个分数段人数均高于三仓中学，但部分学科的均分、达B率仍低于三仓中学，这一成绩与社会、家长、上级的要求相比形势仍然是严峻的，压力是相当大的。本届高三聘用教师69人，语文12人，数学15人，英语12人， 6门选科用27人，体育3人。 二、指导思想 以“一切为了学生的美好未来”为宗旨，以“班之为战、科之为战、有效教研、全面超越”为策略，深化课堂教学改革、扎实推进有效教学，科学管理、合理调控、优化配置、加强督导与考核，使学生成人成才，创XX年高考佳绩。 三、管理队伍 学校校长、党总支书记卢惠斌老师亲自督查协调高三年级，并建立由副校长、主任、年级组长参加的高三年级管理小组，由分管教学的副校长顾劲松老师担任年级分管校长，教务处副主任贾新荣老师担任年级分管主任，年级分为两个部，一部部长为办公室副主任任益老师，副部长为教科室副主任姜波老师；二部部长为贾新荣兼任， 副部长为政教处副主任朱世权老师。省优秀班主任、高三15班班主任王如玉老师担任年级组长。高三17位班主任中有省、县级优秀班主任5人，老中青结合，有9人是原高三留任的。 四、年级目标
