Do you sometimes put off doing your homework on a school night to watch TV？A new study says that middle school students who watch TV or play video games during the week do worse in school．The study also says that watching TV and playing video games on weekends don’t affect school performance that much．
“They could watch a lot on weekends and it didn’t seem to connect with doing worse in school，”said Dr．Iman Sharif of Children’s Hospital at Montefiore in New York．The study appears in the October issue of Pediatrics．Researchers drew their conclusions after surveying （调查）4，500 students in New Hampshire and Vermont middle schools．
To reach their findings，researchers didn’t look at grades or test scores．Instead，they asked students to rate their own performance on a scale ranging from “excellent’’ to “below”．
Other studies have found a connection between kids’ ability to learn and the amount of TV they watch．One study even found that kids with televisions in their bedrooms scored about eight points lower on math and language arts tests than kids without them．

In 1987, while serving as the public affairs officer at Fort Bragg, I would frequently visit the local high schools to speak to the students about the Army. As a lieutenant colonel(中校), I found it particularly rewarding to talk with the teenagers about the benefits of military service, if only for a few years of their lives.
During one of these visits, I reported to the secretary in the principal’s office to let her know that I was here for the third-period class. I was a little surprised when she told me. “The principal would like to see you before you go to the class.”
As I entered his office, I was greeted by a gentleman who appeared to be in his late thirties, and he welcomed me with a smile and a handshake. “You don’t remember me, do you?” he said.
I looked closely at the face again and could not recall where we may have met before.
“You were my company commander in basic training at Fort Jackson in 1970,” the principal said.
“Let me help you out,” he suggested. “You gave me a three-day pass to go home and see my newborn baby.” I immediately remembered the incident!
“Yes,” I said. “I remember now.” It was the only three-day pass I had issued because the soldiers were on their way to Vietnam immediately after they finished training. But I knew if I did not let him go home to see his son and something happened to him, I would regret denying the opportunity he had to be with his family.
“Come on, Colonel. I’d like to introduce you to ‘the baby’. He’s in your third-period class. By letting me go see him, you gave me a reason to stay focused and to come home safe from that war. Thank you , sir.”
It was the most rewarding class I had ever given, and I had no problem in telling the students about the bonds of friendship and the values that Army life can provide…and that can last a lifetime. In the writer’s opinion, talking to teens about the Army is .
| A．a forced task | B．a pleasant thing |

| C．the soldier may die in the war | D．the soldier may be hurt in the training |
What might be the most suitable title for the text?

Since new technologies are ever growing, employers now have the chance to monitor （监控） their employees to make them spare more time to work when they use their phones, computer terminals, emails and even when an employee is using the Internet．
Recent surveys have shown that a majority of employers monitor their employees’ activities．It was found that three fourths of employers monitored the websites their employees visited in order to prevent improper surfing．The survey further indicated that 65% of employers used software to block connections to websites considered off limits to employees．One third of employers monitored their employees’ number of keystrokes and the amount of time spent on the keyboard and lastly just over half of the employers surveyed review and kept email messages．
Most of the time, email is not considered private if the email system is used at a company, the employer owns it and is allowed to review its contents．Email messages that are sent within the company, as well as those that are sent from the employee’s terminal to another company, or from another company to the employee are subject to monitoring．If an email is deleted out of the employee’s account, that doesn’t mean that they are totally deleted．The messages are kept in memory．Emails are often backed up along with other important data from the computer system．If an employer’s email policy specifically states that messages marked as “private” will be kept confidential （机密的）,however, there may also be some exceptions to that policy （政策）．
In order to know their employer’s email policy, employees should read over the employee handbook．If the handbook doesn’t address the issue of email monitoring, they should speak with their employer about their policy for emails and privacy．Currently there are very few laws that address workplace privacy; however, there are some organizations that are working to advocate for employees so that there will be a stronger government regulation of employee monitoring activities．According to the author, the employers’ monitoring ____．
| A．may be an efficient management method |
| B．should be performed secretly |
| C．has resulted from the development in computers |
| D．is quite common nowadays |
Employers probably think that monitoring the employees can help them ____．
| A．improve their work efficiency（有效） | B．use computers properly |
| C．develop a way of keeping office secrets | D．reduce their mental pressures |
It can be inferred from the passage that ____．
| A．employees should delete their own emails at once to keep them secret |
| B．an employer’s email policy may protect the employees’ privacy |
| C．nobody can help solve the problem of office privacy |
| D．an employee may feel troubled by being monitored in the office |
The underlined phrase “advocate for” in the last paragraph means “____”．
| A．tell the employees the truth |
| B．publicly support |
| C．ask the employees to be more attentive |
| D．remind the employees of the possible failure |
Have you ever stayed in a hotel? Most Chinese hotels often provide guests with things like disposable (一次性的) toothbrushes, toothpaste, shampoo and slippers. Many guests like the idea because they don't have to bring their own. But, if you travel to Beijing, remember to bring your own things. Starting from June, some hotels in Beijing will no longer provide guests with these disposables. They want to ask people to use less disposable things.
Many disposable things are made of plastic. People throw them away after only using them once. It is a waste of natural resources and is very bad for the environment. Do you know, one Chinese person makes as much as 400kg of waste a year! Most of that waste comes from disposable things. In Beijing, people throw away about 19,000 tons of plastic bags and 1,320 tons of plastic lunch bowls every year! Plastic can take between 100 and 400 years to break down. So the less plastic we throw out, the better. So, wherever you travel, bring your own things and use them again and again.
Back at home and school, you can also do something to make our world a better place. Try to do these things in your daily life: Use cloth shopping bags, not plastic ones. After using a plastic bag, wash it out and let it dry. Then you can use it over and over again. Do not use paper cups. At your school canteen（食堂）, use your own bowl and chopsticks instead of disposable ones. Some Beijing hotels will no longer provide guests with ____.
| A．cheap food and drink | B．disposable things |
| C．good service | D．free TV programmes |
Which of the following is NOT true?
| A．Many disposable things are made of plastic. |

What can we do to make our world a better place at home and school?
| A．Use shopping bags made of plastic. | B．Do not throw away paper cups. |
| C．Use disposable plates, bowls and chopsticks. | |
| D．Do not forget to reuse daily necessities. |
We can tell from the story that ____.
| A．people don't like disposable things at all |
| B．we can't use paper or plastic bowls at school |
| C．we should use less plastic things and protect our environment |

Many Americans have been leaving their cars at home and riding to work on bicycles. Andy Clark is the leader of the League of American Bicyclists. His group supports bicycling for fun, fitness and transportation.
Clark says this is good news for the environment. He says riding a bicycle to work does not burn fossil fuel or creates dangerous pollutions. Experts say the effects are the most important on short trips. The Department of Transportation says fifty percent of Americans drive eight kilometers or fewer to work. Shorter car trips set out more pollution into the air for each kilometer drive. This is because the car engine will set out the harmful air when it warms up before it can work well.
James, a members of Congress (国会), is a strong supporter of bicycle use. He says cities, counties, state governments and state highway transportation agencies are planning the roadways of the future. They are creating roads and paths for bicycles in cities and between communities.
Last year, Portland, the Pacific Northwest city in the state of Oregon, had the highest percentage of bicycle users in the United States. Portland has been doing progressive city planning for many years to create special paths for bike riders. What happened in America now according to the news?
| A．Many Americans lost jobs now. |
| B．Many Americans prefer short trips. |
| C．There are more and more bicyclists now in America. |
| D．The pollution is getting worse and worse in America. |
Where is Portland?
A. One of the cities in the USA. B. One of the counties in the USA.
C. One of the states in the USA. D. A country in the northwest of the USA.What does the underlined word “harmful” mean in the second paragraph? The closest meaning is “_______”.
| A．polluted | B．dangerous | C．clean | D．foolish |
What is the main idea of the passage?

| B．Short car trips can reduce pollution. |
| C．American government suggests people riding bicycles. |
| D．Many Americans ride bicycles to support environment protection. |
I once experienced an unforgettable trip to Gloucester to see some of the world's most beautiful and exciting animals in their own habitat(栖息地), the North Atlantic Ocean.
After a long trip by bus, we got on the ship. After a while, we stopped and everyone on the ship started to shout because we saw a humpback whale(座头鲸). It was wonderful. Sometimes, whales came so close to the ship that you thought you could easily touch them.
While we were watching the whales, a guide was giving us some information about them. She told us that we saw only two kinds of whales -- 50-foot humpback whales (singing whales) and 70-foot fin back whales (the second largest whales on earth). She also said we could easily recognize a whale by its tail because every whale has a different kind of tail just like people have different fingerprints.
They all have names, and on this trip, we saw "Salt" and "Pepper", two whales named by a biologist and a fisherman. They were swimming together all the time.
I took twenty-seven photos, but it was very hard to take them because the whales were quick and stayed on the surface(表面) of the ocean just for a short time. It was really something. It was one of the chances that a person hardly ever experiences in life, but I had that chance.This passage is mainly about ____.
| A．an unforgettable experience in the forest |

Everyone on the ship began to shout because ______.

| A．some of them fed the whales |
| B．they found several kinds of whales |
| C．a guide told them something about the whales |
| D．some of them took many photos and touched the whales |
