Teamwork is just as important in science as it is on the playing field or in the gym. Scientific investigations (调查) are almost always carried out by teams of people working together. Ideas are shared, experiments are designed, data are analyzed, and results are evaluated and shared with other investigators. Group work is necessary, and is usually more productive than working alone.

Several times throughout the year you may be asked to work with one or more of your classmates. Whatever the task your group is assigned, a few rules need to be followed to ensure a productive and successful experience.

What comes first is to keep an open mind, because everyone’s ideas deserve consideration and each group member can make his or her own contribution. Secondly, it makes a job easier to divide the group task among all group members. Choose a role on the team that is best suited to your particular strengths. Thirdly, always work together, take turns, and encourage each other by listening, clarifying, and trusting one another. Mutual （相互的）support and trust often makes a great difference.

Activities like investigations are most effective when done by small groups. Here are some more suggestions for effective team performance during these activities: Make sure each group member understands and agrees to the task given to him or her, and everyone knows exactly when , why and what to do; take turns doing various tasks during similar and repeated activities; be aware of where other group members are and what they are doing so as to ensure safety; be responsible for your own learning, though it is by no means unwise to compare your observations with those of other group members.

When there is research to be done, divide the topic into several areas, and this can explore the issue in a very detailed way. You are encouraged to keep records of the sources used by each person, which helps you trace back to the origin of the problems that may happen unexpectedly. A format for exchanging information (e.g., photocopies of notes , oral discussion, etc.) is also important, for a well-chosen method not only strengthens what you present but also makes yourself easily understood. When the time comes to make a decision and take a position on an issue, allow for the contributions of each member of the group. Most important of all, it is always wise to make decisions by compromise and agreement.

After you’ve completed a task with your team, make an evaluation of the team’s effectiveness — the strengths and weaknesses, opportunities and challenges.

Today, there’s hardly an aspect of our life that isn’t being upended by the tons of information available on the hundreds of millions of sites crowding the Internet, not to mention its ability to keep us in constant touch with each other via electronic mail. “If the automobile and aerospace technology had exploded at the same pace as computer and information technology,” says Microsoft, “a new car would cost about $ 2 and go 600 miles on a small quantity of gas. And you could buy a Boeing 747 for the cost of a pizza.”
Probably the biggest payoff, however, is the billions of dollars the Internet is saving companies in producing goods and serving for the needs of their customers. Nothing like it has been seen since the beginning of the Industrial Revolution, when power-driven machines began producing more in a day than men could turn out in nearly a year. “We view the growth of the Internet and e-commerce as a global trend,” says Merrill Lynch, “along the lines of printing press, the telephone, the computer, and electricity.”
You would be hard pressed to name something that isn’t available on the Internet. Consider: books, health care, movie tickets, construction materials, baby clothes, stocks, cattle feed, music, electronics, antiques, tools, real estate, toys, autographs of famous people, wine and airline tickets. And even after you’ve moved on to your final resting place, there’s no reason those you love can’t keep in touch. A company called FinalThoughts.com offers a place for you to store “afterlife e-mails” you can send to Heaven with the help of a “guardian angel”.
Kids today are so computer literate that it in fact ensures the United States will remain the unchallenged leader in cyberspace for the foreseeable future. Nearly all children in families with incomes of more than $75,000 a year have home computers, according to a study by the David and Lucile Packard Foundation. Youngsters from ages 2 to 17 at all income levels have computers, with 52% of those connected to the Internet. Most kids use computers to play games (some for 30 hours or more a week), and many teenage girls think nothing of rushing home from school to have e-mail chats with friends they have just left.
What’s clear is that, whether we like it or not, the Internet is an ever growing part of our lives and there is no turning back. “The Internet is just 20% invented,” says cyber pioneer Jake Winebaum. “The last 80% is happening now.”
【小题1】What can we learn from the Microsoft’s remark?

A．There is a link between income and computer ownership.

B．Many American children don’t put computers to good use.

C．Studies show that boys are more computer literate than girls.

D．The U.S. will stay ahead in the information technology in years.

The extraordinary Eastgate Building in Harare, Zimbabwe’s capital city, is said to be the only one in the world to use the same cooling and heating principles as the termite mound(白蚁堆).

????????????? Architect Mick Pearce used precisely the same strategy when designing the Eastgate Building, which has no air-conditioning and almost no heating. The building—the country’s largest commercial and shopping complex—uses less than 10% of the energy of a conventional building of its size. The Eastgate’s owners saved $3.5 million on a $36 million building because an air-conditioning plant didn’t have to be imported.

The complex is actually two buildings linked by bridges across a shady, glass-roofed atrium(天井) open to the air. Fans suck fresh air in from the atrium, blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents(通风口). As it rises and warms, it is drawn out via ceiling vents and finally exists through forty-eight brick chimneys.

????????????? During summer’s cool nights, big fans blow air through the building seven times an hour to cool the empty floors. By day, smaller fans blow two changes of air an hour through the building, to circulate the air which has been in contact with the cool floors. For winter days, there are small heaters in the vents.

????????????? This is all possible only because Harare is 1600 feet above sea level, has cloudless skies, little dampness and rapid temperature swings—days as warm as 31℃ commonly drop to 14℃ at night. “You couldn’t do this in New York, with its fantastically hot summers and fantastically cold winters,” Pearce said.

The engineering firm of Ove? Arup&Partners monitors daily temperatures. It is found that the temperature of the building has generally stayed between 23℃ and 25℃, with the exception of the annual hot period just before the summer rains in October and three days in November, when a doorkeeper accidentally switched off the fans at night. And the air is fresh—far more so than in air-conditioned building, where up to 30% of the air is recycled.

About ten percent of spending on primary and secondary education in the United States comes from the federal government. 1.________States have been required to show progress through yearly testing.

But states say testing tells only part of the story about efforts by schools and students to improve. So the Obama administration has eased the limits on states in measuring performance.

2.________This new measurement tool is called the Colorado Growth Model. The idea is to show academic growth, not just achievement on tests. It combines test scores, family income levels, school size, the ethnicity of the student and many other factors.

3._______The graph shows a school’s average score on standardized tests as well as its academic growth.

On average, students enter sixth grade at WEST Denver Prep performing below grade level. 4.________.

The new assessment method shows that, each year, the average West Denver Prep student learns more math than ninety-four percent of all the students in Colorado. 5._________.

 Josh Smith says perhaps the most important thing they should learn is to believe in themselves.

A.The results from schools across the state are shown online on a graph.

B.Reading and writing scores also show growth.

C.For ten years now, federal law has tied this spending to student performance.

D.Therefore, the government feels it a great pressure.

E.But three years later, most are outperforming other students across the state.

F.However, the limits don’t work at all.
