But the implications of not using technology in an increasingly technology-laden world may

be even more unsatisfactory. Computers and access to the Internet are now common features in most American schools, but they have taken a long and winding road to get there, so quick and widely shared improvements in math and science test scores may be unrealistic. Also, the use of computers in classrooms does not necessarily mean that science and math curricula have been adjusted to take full advantage of them. And a widely perceived lack of teacher training prevents many teachers from effectively implementing both the technology and new approaches to teaching.

"Technology access is important," says Roberts. "But technology alone never makes the difference in student performance. It's equally important [ to have] teachers who are comfortable and competent with technology, and who have the right kind of training and support."

Federal funding for public school technology, which goes directly to the states, is $ 425 million this year. About one-third of that amount is earmarked for professional development.

In some cases, technology can help move both teachers and students toward their goals. One of Roberts' favorite Web sites is Ask Dr. Math, which can help teachers and students struggling with difficult material. Ask Dr. Math is a question and answer service for K-12 math students and their teachers; it has received a number of Internet awards, including the Best Education Site Award. You can search an archive of questions and answers by level and topic, and students and teachers can e-mail their specific questions as well. E-mail answers come courtesy of 225 volunteer math "doctors" from all over the world.

But teachers need some formal technology training too. That' s the objective of the W. M. Keck Summer Technology Institute, which takes place at the Thacher School, a 110-year-old boarding school in Ojai, California. With a $ 280,000 grant from the Keck Foundation, the school accepts Southern California teachers for intensive training in using computers, the Internet, and a gaggle of high-tech equipment. The one-week summer sessions began in 1997, continued in 1998, and will repeat in 1999. Roughly 60 percent of the attendees are math and science teachers.

Ask Dr. Math could be described as the following EXCEPT ______.

A．a question and answer service

B．a technology training program

C．with a database of questions and answers

D．supported by volunteer math teachers

第1题
To begin with, moral values in America are like those in any culture. But the stories and traditions that teach them are unique to each culture. Not only that, but culture has an effect on how people show these virtues.

One of the most basic moral values for Americans is honesty. The wall-known legend about George Washington and a cherry tree teaches this value clearly.

Another virtue Americans respect is perseverance. Remember Aesop’s fable about the turtle and the rabbit that had a race The rabbit thought he could win easily, so he took a sleep. But the turtle finally won because he did not give up.

Compassion(同情心)may be the queen of American virtues. In 1992, people in Iowa sent truckloads of water to help Floridians hit by a hurricane. The next summer, during the mid-west of flooding, Florida returned the favor.

There are more moral values honored by Americans. Courage, responsibility, loyalty, gratitude and many others could be discussed. But no matter how long or short the list is, moral values are invaluable. They are the foundation of American cultures--and any culture.

第4题
Shortages of flu vaccine are nothing new in America, but this year' s is a whopper. Until last week, it appeared that 100 million Americans would have access to flu shots this fall. Then British authorities, concerned about quality-control problems at a production plant in Liverpool, barred all further shipments by the Chiron Corp. Overnight, the U.S. vaccine supply dwindled by nearly half and federal health officials found themselves making an unusual plea. Instead of beseeching us all to get vaccinated, they' re now urging most healthy people between the ages of 2 and 64 not to. "This reemphasizes the fragility of our vaccine supply," says Dr. Martin Myers of the National Network for Immunization Information, "and the lack of redundancy in our system."

Why is such a basic health service so easily knocked out? Mainly because private companies have had little incentive to pursue it. To create a single dose of flu vaccine, a manufacturer has to grow live virus in a 2-week-old fertilized chicken egg, then crack the egg, harvest the virus and extract the proteins used to provoke an immune response. Profit margins are narrow, demand is fickle and, because each year's flu virus is different, any leftover vaccine goes to waste. As a result, the United States now has only two major suppliers ( Chiron and Aventis Pasteur)--and when one of them runs into trouble, there isn' t much the other can do about it. "A vaccine maker can't just call up and order 40 million more fertilized eggs," says Manon Cox, of Connecticut-based Protein Sciences Corp. "There's a whole industry that's scheduled to produce a certain number of eggs at a certain time. "

Sleeker technologies are now in the works, and experts are hoping that this year's fiasco will speed the pace of innovation. The main challenge is to shift production from eggs into cell cultures--a medium already used to make most other vaccines. Flu vaccines are harder than most to produce this way, but several biotech companies are now pursuing this strategy, and one culture-based product (Solvay Pharmaceuticals' Invivac) has been cleared for marketing in Europe.

For Americans, the immediate challenge is to make the most of a limited supply. The government estimates that 95 million people still qualify for shots under the voluntary restrictions announced last week. That' s nearly twice the number of doses that clinics will have on hand, but only 60 million Americans seek out shots in a normal year. In fact, many experts are hoping the shortage will serve as an awareness campaign--encouraging the people who really need a flu shot to get one.

Shortages of flue vaccine show that ______.

A．America relies too much on foreign suppliers

B．the demand of flue vaccines is high this year

C．quality problem is a serious problem in flu vaccine production

D．the supply of flu vaccines is rather weak and America has no back-up measures to make it up

第5题

In a fmily where the roles of men and women are not sharply sparate and where many houschold tasks are shared to a greater or less extent, cocepts of male supeoririty are hard to mainain. The pattern of sharing in tasks and in decsions makes for equality, and this in turn leads to further sharing. In such a home, the growing boy and girl learn to accept that equality more easily than did their parents and to prepare more fully for participation in a world characterized by coperaton rather than by “battle of the sexes” If the process goes too far and man’s role is regarded as less important and that has happened in some cases, we are as badly off as before, only in reverse. It is time to re-estimate the role of the man in the American family. We are geting a little tired of “Monism”(一元论), but we don’t want to exchange it for a “new-Monism”. What we need, rather, is the recognition that bringing up children involves a partnership of equals. There are signs that psychologists, social workers, and specialists in family are becoming more aware of the part men play. We have almost given up saying that a woman’s place is in the home. We are beginning, however, to analyze man’s place in the home and to insist that he does have a place in it. Nor is that place irrelevant to the healthy development of the child. The family is co-operative enterprise for which it is dfficult to lay down rules, because each family needs to work out its own ways for solving its own problems. Excessive authority has unhappy consequences, whether it wears skirts or trousers; the ideal of equal rights and equal responsibilies is relative not only to a healthy democracy, but also to a healthy family. Q: The consequences of excessive authority in the home .

A、are unfortunate whoever is the head of the family

B、are fortunate if the mother is the only authority

C、have never proved dangerous

D、are fortunate if the father is the only authority
