While Jennifer was at home taking an online exam for her business law class, a monitor（监控器）a few hundred miles away was watching her every move.
Using a web camera equipped in Jennifer’s Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked - remotely - to prevent Internet searches , and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down?
In the battle against cheating, this is the cutting edge and a key to encourage honesty in the booming field of online education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid - that students haven’t just searched the Internet to get the right answers.
Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses." Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.
Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students’ identities using personal information, such as the telephone number they once used.
Other programs can produce unique exam by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test question are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.Why was Jennifer watched in an online exam?
| A．To correct her typing mistakes. |
| B．To find her secrets in the room. |
| C．To prevent her from slowing down. |
| D．To keep her from dishonest behaviors. |

At the age of seven I started taking violin lessons. I practiced half an hour every day, went to lessons once a week, and occasionally played in a group concert. Like most kids, I always thought practicing was boring. If my parents hadn’t been there to make me practice, I probably would have put down my violin and never have picked it up again.
I met Moira when I was 11 at an Irish music party. Moira hosted the party that night, playing the violin, singing and dancing. She made sure that everyone in the room got involved and had a great time. I immediately fell in love with the music she played and the energy that she brought to it. Just a few days after that party, I took my first lesson with Moira, and I continued taking lessons with Moira throughout middle school.
When I started playing the violin with Moira, playing music became something that I loved. She introduced me to so many types of music, from Irish to Old Time, to Cajun. Moira also taught me to play the guitar. Soon we started performing together and were shocked to discover that people actually wanted to hear us! When I began to play the violin, practicing was something that I did at home in my living room, but with Moira’s influence it quickly became something that I did everywhere. I played on street corners, at festivals, at the beach, at parties, at weddings, and late at night in my friends’ kitchens.
Moira took the music out to the classroom and brought it to life. Her passion(激情)was not only for playing music, but also for sharing it.

As a student, you must be excited to know something about American school students. In fact, just like in China, in the United States, high school is usually divided into two periods, the first two or three years are called “junior high school” and the other is “senior high school”.
In China, children enjoy free education of nine years, but in the United States, the students enjoy free education(which will be started when they are about 6 years old) until they are 18 years old. As a result of the free education system, American children have little difficulty in going to senior high school.
American high school students can take part in a lot of activities outside of the classroom. The activities are organized by the school, such as joining a music group or a sports team. Certainly, just like us students in China, American students have to work hard in order to get good marks if they want to go to a good university. They take classes in all kinds of subjects all through the high school period. And students with low marks at the end of a school year are still allowed to go on to the next grade.
In American high schools, there is fighting or hurting or other kinds of bad behaviors. So children who want to go to university are often sent to suburban (郊区的) high schools, where most students want to go to university and the atmosphere (氛围) is quite different.This passage mainly tells us about ________.
| A．education of Chinese middle school |
| B．education of American high school |
| C．American free education |
| D．how to get into universities in America |
Which of the following statements is NOT true?
| A．The time of free education in China is longer than that in America. |
| B．Those who get good marks can go to a good university. |
| C．American students can take all kinds of subjects during the high school period. |
| D．They can be allowed to join the next grade even if they fail the school-year exam. |
The writer of the passage tells us the truth that ________.
| A．the atmosphere in high schools is not good |
| B．none of the schools in cities are good for learning |
| C．suburban high schools are good places for learning |
| D．all the American students want to go to university |
“Come on! All of us are cutting math. Who wants to take that quiz? We’re going to take a walk and get lunch instead. Let’s go!” says the coolest kid in your class. Do you do what you know is right and go to math class, take the quiz? Or do you give in and go with them?
People who are at your age, like your classmates, are called peers（同龄人）. When they try to influence you how to act, to get you to do something, it’s called peer pressure（压力）. It’s something everyone has to deal with—even adults.
Peers influence your life, even if you don’t realize it, just by spending time with you. You learn from them, and they learn from you. It’s only human nature to listen to and learn from other people in your age group.
Peers can have a positive influence on each other. Maybe another student in your science class taught you an easy way to remember the planets in the solar system. Or you got others excited about your new favorite book, and now everyone is reading it. Sometimes peers influence each other in negative（消极的） ways. For example, a few kids in school might try to get you to cut class with them.
It’s difficult to say “no” to peer pressure, but you can do it. Paying attention to your own feelings and beliefs about what is right and wrong can help you know the right thing to do.
It can really help to have at least one other peer, or friend, who is willing to say “no” too. If you continue to face peer pressure and you’re finding it difficult to handle, talk to someone you trust, a parent, or a teacher. They can help you feel much better and prepare you for the next time you face peer pressure.With his words in the first paragraph, the kid is ________.
| A．planning some interesting activities after school |
| B．talking about a dinner party |
| C．asking other kids to take a quiz with him |
| D．encouraging other kids to cut a class |

Think of life as a game in which you are playing with five balls in the air. You name them work, family, health, friends and spirit and you keep all of them in the air. You will soon understand that work is a rubber ball. If you drop it, it will bounce (弹跳) back.
But the other four balls, family, health, friends and spirit, are made of glass. If you drop one of these, they will be broken. They will never be the same. You must understand that and try to have balance in your life. How?
Don’t look down on your worth by comparing yourself with others. It is because we are different and each of us is special.
Don’t let other people set goal for you. Only you know what is best for yourself.
Don’t give up when you still have something to give. Nothing is really over until the moment you stop trying.
Don’t be afraid of difficulties. It is by taking chances that we learn how to be brave.
Don’t shut love out of your life by saying it’s impossible. The quickest way to receive love is to give it; the fastest way to lose love is to hold it too tightly; the best way to keep love is to give it wings（翅膀).
Don’t run through life so fast that you forget not only where you’ve been, but also where you are going.
Don’t be afraid to learn. Knowledge is a treasure you can always carry easily.
Don’t use time or words carelessly. You can’t get them back. Yesterday is history, tomorrow is a mystery, and today is a gift; that’s why we call it “the present”. Life is not a competition, but a trip, step by step.The passage tells us not to _________ because everyone is special.

The planet is getting greener, and we are responsible. Carbon dioxide generated by human activities is promoting photosynthesis (光合作用) and causing a beneficial greening of the Earth’s surface.
For the first time, researchers claim to have shown that the increase in plant cover is due to this “CO2 fertilisation (肥沃化) effect” rather than other causes. However, it remains unclear whether the effect can reduce any negative effects of global warming, such as the spread of deserts.
To home in on the effect of CO2, Randall Donohue of Australia’s national research institute, the CSIRO in Canberra, monitored vegetation (植被) at the edges of deserts in Australia, southern Africa, the US Southwest, North Africa, the Middle East and central Asia. These are regions where there is plenty of warmth and sunlight, but only just enough rainfall for vegetation to grow, so any change in plant cover must be the result of a change in rainfall patterns or CO2 levels, or both.
If CO2 levels were constant, then the amount of vegetation per unit of rainfall ought to be constant, too. However, the team found that this figure rose by 11 per cent in these areas between 1982 and 2010, mirroring the rise in CO2 emissions (排放). Donohue says this lends strong support to the idea that CO2 fertilization drove the greening.
The extra plant growth could have knock-on effects on climate, Donohue says, by increasing rainfall, affecting river flows and changing the likelihood of wildfires. It will also absorb more CO2 from the air, potentially damping down (抑制) global warming but also limiting the CO2 fertilization effect itself.
Donohue cannot yet say to what extent CO2 fertilisation will affect vegetation in the coming decades. But if it proves to be significant, the future may be much greener.According to the author, the increase in plant cover _____.
| A．will speed up global warming |
| B．results from human activities |
| C．will stop the spread of deserts |
| D．promotes the CO2 fertilization effect |
What does the underlined phrase “To home in on” in Para 3 probably mean?
| A．To hold back. | B．To cut down. |
| C．To improve. | D．To observe. |
The amount of vegetation in those monitored areas rose with _____.
| A．the rise in CO2 emissions | B．annual rainfall |
| C．the temperatures around | D．the amount of sunlight |
What’s the best title of the text?
| A．More rainfall, less CO2 emission |
| B．How to deal with carbon emissions |
| C．Positive effects of global warming |
| D．CO2 emission making Earth greener |
