It began as a game: High school and college students studying computer technology figured out they could use personal computers to break into telephone company computers and make free, long-distance telephone calls. These young computer talents soon gained the name "hackers".
Police arrested a few hackers, but many went on to even more complex hacking. One of them was arrested for making illegal telephone calls and later he used a phone to change a police officer's credit records to get back at the officer for arresting him. He also used a computer to change his college records to give himself better grades.
As hackers gained experience, they began invading computers at banks, airlines and other businesses. In one case a hacker instructed an airline' s computer to give him free airplane tickets.
The U.S. government is worried that hackers may break into its networks of defense computers. The government's secrets are easily attacked because thousands of government computers are connected by telephone lines that hackers can get into.
In November 1988, a college student entered a U.S. Defense Department computer network called Arpanet. The hacker injected a computer program that made copies of itself throughout Arpanet. Some hackers use viruses to destroy all the data in a computer. But in this case, government officials shut down the network before the program reached every computer in the system. Shutting down the system angered many researchers who were using the computers. The hacker turned himself in to the police and he was charged with a crime.
The incident put the spotlight on computer hacking in the United States. Many companies have hired experts to protect their computers from hackers, and many computer experts now advise companies on how to protect their computers.
The U.S. government believes foreign governments have hired hackers to try to break into top-secret defense computers.
Experts disagree over whether a computer network can ever be safe from hacking. But in the future, some of the most outstanding minds in the U.S. will be working to frustrate the attempts of computer hackers.
1.What did the first hackers do?

Throughout high school, I failed to volunteer as much as I had wanted. As a college student, I am still busy with maintaining my grades and staying involved in my school’s community, but I decided to get out of my comfort zone and volunteer for America Recycles Day. And this turned out to be an awesome experience.
The organization Ouachita Green put together this event, which allowed people from the Monroe area of Louisiana to bring in their recyclables, free of charge. Unfortunately, Louisiana is lacking in environmentally-friendly initiatives(倡议) so recycling is not offered to most people in our community. In contrast, it is required by law to recycle back in my home New Jersey. This truth astonished me, but more importantly, it encouraged me to seek change.
I meant to make a difference. Through joint efforts, my classmates and I ended up starting the Green Club at the University of Louisiana. It focuses on creating a green attitude within the university and the greater Monroe area. While working on it, I met a group of ambitious high school students, who shared the same concern about the environment as us. While talking, we decided that working together would benefit not only the organizations at our schools, but also the community as a whole. Is we let the community know we are serious, there is an even better chance that we will succeed and influence others.
If you are hesitant to volunteer or help out with an event in your community, my recommendation is to go ahead and do it. Even if it may be out of your comfort zone, it is important to put yourself out there. At the end of the day, you miss all of the shots you don’t take.
1.What surprised the author greatly?
A. Louisiana’s lack of environmental laws

A. offer part-time jobs for high school students
B. appeal for an environmentally-friendly lifestyle
C. make university life in the Monroe area colorful
D. help with community events in the Monroe area

高三英语单项填空中等难度题查看答案及解析
High school students and families are increasingly questioning whether investing in a college or university education is still worth it.
The short answer is “Yes.” 1. A wide range of statistics shows the economic advantage of a four-year college education. Over a lifetime, students who graduate from college can expect to make about 60% more than those who do not, well over a million dollars more than they would otherwise. 2. They vote more often, volunteer more often and are more likely to own a home. They are healthier and less likely to smoke. They and their children are less likely to be overweight, and their children are more likely to go to college.
But what about the benefits of college that are more difficult to measure? 3.
College takes students to places they’ve never been before. College is a passport to different places, different times, and different ways of thinking. It gives students a chance to understand themselves differently, seeing how their lives are both like and unlike those who inhabited other times and other lands. 4.
College introduces students to people they’ve never met before. One of the most important ways in which students learn, at colleges and universities everywhere, is by communicating with people who are different from themselves both inside and outside of the classroom.
5. No one doubts the value of speed, connectivity (网络连通性) and the virtual world in an economy that enjoys all three. But “thinking” is a word that is too often forgotten in our rush to communicate faster and left behind as our brains struggle to keep up with our devices (设备). College teaches students to change information to insight and knowing to understanding, preparing students for lifetime of considering information and growing in knowledge and in wisdom.
Higher education is valued by people who dream bigger and achieve more, who create their own futures, and shape their own destinies.
A. There is no doubt that college pays off financially.
B. College teaches students the virtue of slowing down.
C. College graduates also tend to lead more active lives.
D. Education encourages people to live healthier and longer lives.
E. College opens minds and worlds in ways that are beyond measurement.
F. For many of us, it is the best chance we will have to follow our curiosity.
G. They are equally significant and add up to a lot of value over the course of a lifetime.

高三英语阅读理解中等难度题查看答案及解析
This is a time of year when high school students and their families are thinking hard about college. As seniors，juniors，and parents identify their top choices，discussions typically focus on the college itself. Is the institution small or large? How strong are the academics？What is the social life like? Do I like the campus? Such considerations are important, but they can cover the all-important question：Where will these college years lead?
Applicants should think seriously about which college on their list can best prepare them for the real world. They should look for campuses that offer well-structured programs to help them form a direction for their lives and develop the capacity to take steps along that path.
One of the most striking recent phenomena about college graduates in America has been the “boomerang” student: the young person who goes away to college, has a great experience, graduates, and then moves back home for a year or two to figure out what to do with his or her life. This pattern has left many graduates – and their families – wondering whether it makes sense to spend four or more years at college, often at great expense, and finish with no clear sense of who they are or what they want to do next.
The trend points to one of the great shortcomings of many of our nation’s leading colleges and universities. Structured opportunities to think about life after graduation are rare. The formal curriculum focuses almost universally on the academic disciplines of the arts and sciences. Advising on how various majors connect to pathways into the workplace is typically haphazard (没有条理的). Career planning offices are often shorthanded and marginal (不重要的) to college life.
It doesn’t need to be this way, and in recent years some of the country’s top colleges have enriched their academic offerings with opportunities for students to gain real-world experiences.
1.According to the author, what do typical discussions on college choices ignore?
A. The function of college education in employment.
B. The difficulty in finding jobs after graduation.
C. High school students’ interests.
D. The academics of college.
2.Which accounts for the “trend” mentioned in the text?
A. Students failing to behave themselves.
B. Parents overprotecting their children.
C. Students choosing majors blindly.
D. Schools lacking proper guidance.
3.What will be probably discussed in the following paragraph?
A. Recipes for academic achievements.
B. Good academic programs in college.
C. Academic tips for college students.
D. Disadvantages of present college course.
4.What is the best title for the text?
A. A good way to choose a college.
B. A new trend in top colleges.
C. Connect subjects with life beyond college.
D. Make college one of life’s richest experiences.
高三英语阅读理解中等难度题查看答案及解析
As a public school superintendent(督导), I believe the best way to prepare students for colleges and careers is to focus on providing instructional programs and opportunities that help them become good thinkers. To do this, teachers and actually everyone else in a community, should play a role as a “cognitive coach” to students, helping develop good thinkers among our youth.
The best way for you to become a cognitive coach is to seek out and engage school children and adolescents in meaningful conversations. The objective here is to get kids talking about what they think, how they feel, and what they believe whenever and wherever you may find them. It may be in a classroom. It may be at the grocery store. It may be at a basketball game. It doesn’t matter where as long as you engage students in a topical conversation and, hopefully, even a debate. Mainly, you want to encourage students to voice their opinion about things. Get them to take a position on “this thing, or that thing,” and ask them to support their position with evidence. Curiously enough, the simple process of engaging students in real life conversations and debates will serve to strengthen what they have learned in the classroom, and help them create their own knowledge about a subject or a topic.
Learning indicates that a student has been exposed to material, understands the material, and can recall the information. Knowledge, on the other hand, goes beyond recall and includes information processing, application to other situations, consideration of meaning, and contrasting with other concepts. Naturally, the topic of conversation you engage in with one of your learners will differ from student to student, and in the level of complexity based on child’s age and developmental level. Even a kindergartener has an opinion about things that are going on in his or her life. Engaging in conversation with any members of your learning community in ways that get at what they have learned and what they know will help them develop higher order reasoning skills.
A student’s synthetic thinking(综合思维) process occurs when a respected adult asks a question, particularly a question that requires reflection. I think all adults in a community have a responsibility to help children with this process, with the goal of producing independent thinkers.
1.According to writer, what most helps develop students’ thinking?
A. Enlarging one’s knowledge.
B. Learning from respected adults.
C. Attending instructional programs.
D. Making evidence-based arguments.
2.Which is the best question raised by a cognitive coach?
A. What have you learnt recently?
B. Will you pay by the credit card?
C. Where are you going this weekend?
D. How do you like this basketball team?
3.The writer mentions a kindergartener in Paragraph 3 in order to _____.
A. emphasize the importance of being a good thinker
B. suggest that education should start at an early age
C. prove that even children have their own ways of thinking
D. explain the necessity of choosing proper conversation topics
4.What is the main purpose of the passage?
A. To state an education idea.
B. To assess a teaching strategy.
C. To introduce a learning method.
D. To compare different education methods.

Ryan and Lowry had been friends since high school， but it wasn’t until after college that they hit on the idea of a home-care-products company．“We were shocked to learn how toxic cleaning products were” says Ryan．Why couldn’t they create green products that would be just as environmentally pure as Aveda’s skin-and-hair-care lines?
When Ryan’s mom heard about the plan，she stared at him blankly: “I’ve never even seen you clean your room!” Not discouraged，Lowry experimented with nontoxic ways to clean while Ryan focused on marketing．In February 2001，they mixed their first four cleaning sprays and convinced the managers of 20 grocers to try them· Once they had their approval，they tapped friends and family and pooled their savings to come up with $90，000 in seed money．
From the start，“Go big or go home’’ was their mantra(口头禅)．Their first financing— that $l million—was due to be signed on September 11, 2001. By the time they got it, two months later，says Ryan, "we had$16 in the bank and personally owed$300,000.”
Seeking a national retailer(零售商)proved just as troublesome．The friends set their sights on Target，known for its trendy，affordable goods．“But Target didn’t like the product or the brand，”recalled Ryan．“We thought the deal was dead，but then a new buyer saw that even though we weren’t selling big volumes, we were profitable, just on a smaller scale．”They won over Target．
Consumers were hooked on the natural things and wonderful fragrance. Today, the partners sell 130 products in more than 8,000 stores，and taxes are over$100 million. Such rapid growth has at times stressed the men’s friendship. “Eric and I agree on ‘what’ but never on ‘how，’ says Lowry． “Although we are willing to challenge each other，we come up with interesting and smarter solutions．There’s little fire and ice between us.”
