Here’s part of what Bruce has to say about science education…
I consider science education to be critically important to both science and the world, and I shall frequently deal with this topic on this page. Let’s start with a big-picture view. Science has greatly advanced our understanding of the natural world and has enabled the creation of countless medicines and useful devices. It has also led to behaviors that have improved lives. The public appreciates these practical benefits of science, and science and scientists are generally respected, even by those who are not familiar with how science works or what exactly it has discovered.
But society may less appreciate the advantage of having everyone acquire the ways of thinking and behaving that are central to practice of successful science: scientific habits of mind. These habits include a critical attitude toward established claims and a stro

So how does this relate of science education? Might it be possible to encourage, across the world, scientific habits of mind, so as to create more rational (理性的) societies everywhere? In principle, a strong expansion of science education could provide the world with such an opportunity, but only if scientists, educators, and policy-makers redefine (重新定义) the goals of science education, beginning with college-level teaching. Rather than only conveying what science has discovered about the natural world, as is done now in most countrie

Despite what it promiises,GM technology actually has not increased the production potential of any corp. In fact
Studies show that the most crown GM croo.
GM soybeans, has suffered reduced productivity. For instance, a report than analysed nearly two decades of research on mojor GM food crops shows that GM engineering has failed to significantly increase US crop production.
Something else, however, has been on the rise, While GM seeds are expensive, GM companics tell farmers that they will make good profits by saving money on pesticides(***虫剂). On the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops. “ The promise was that you could use less chemicals and boost production. But nether is true,” said Bill Christison, President of the US National Farm Coalition.
At the same time, the authors of the book World Hunger: Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by production, but by problems in food distribution and politics. These indeed deserve our efforts and money. Meanwhile, the rise in food prices results from the increased use of crops for fuel rather than food, according to a 2008 World Bank report.
As a matter of fact ,scientists see better ways to feed the world. Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger, because better ways out are available, among which “green” farming is supposed to be the first choice.

At a children’s center in Baltimore, Maryland, young kids are finding hospital visits easier to deal with, thanks to a test program called HOPE. Patients in HOPE have a life-threatening condition where their kidneys(肾) no longer get rid of wastes from their blood. To get their blood cleaned, these kids must use the dialysis (透析) machines at the hospital three times a week, for at least three hours each time. HOPE allows kids to play Internet sports, racing, and other games with each other. They will be able to connect with kids in other hospitals who have the same problem. “We want to use the Internet to bring together kids who are ill, and let them know they are not alone,” said Arun Mathews, the doctor of the program. He loved video games himself and got the idea to connect kids all over the country.
Many researchers elsewhere are testing video programs that might help young patients. For example, nine-year-old Ben Duskin of San Francisco, California, who was struggling with cancer helped to design a video game where players got rid of cancer cells.
That’s all great news, because doctors already know that reducing pain and worry helps patients heal(痊愈) faster.
小题1:
According to the passage, the sick kids may feel less pain when they _________.
A.use the dialysis machines | B.are in a car race |
C.are playing video games | D.stay alone with illness |
HOPE allows the sick kids to play Internet games in order to _________.
A.encourage them to fight against the illness | B.get rid of their pain and worry |
C.let the kids make more friends | D.bring the kids in the country together |
Which of the following statements is true according to the passage?
A.Grown-ups all think video games are bad for kids’ health. |
B.Some doctors think video games may help the sick kids reduce pain. |
C.The HOPE is a famous organization all over the world. |
D.Arun Mathews is against the testing program. |
Which can be the best title for the passage?
A.Video Games Are Bad for Health | B.Video Games May Help Reduce Pain |
C.A Famous American Organization | D.HOPE Allows Kids to Play Online Games |
I know lots of women who skip breakfast (不吃早餐), and they have a ton of different excuses for doing it . Some say they don’t have time,others think they’re “saving” calories (卡路里), and still others just don’t like breakfast food .
But the bottom line is that eating in the morning is very important when you

Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southem California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.
So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers-it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,” I put away the leftovers instead of eating more that night. Try it,and then you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects.
小题1: The underlined word “leftovers” in Paragraph 1 probably means__________.
A.food remaining after a meal | B.things left undone |
C.meals made of vegetables | D.pizza topped with fruit |
A.Working women usually have breakfast in a hurry. |
B.Many people have wrong ideas about breakfast. |
C.There are some easy ways of cooking a meal. |
D.Eating vegetables helps save energy. |
A.eat something for breakfast | B.be careful about what you eat |
C.heat up food before eating it | D.eat calorie-controlled food |
A.who go to work early | B.who want to lose weight |
C.who stay up late | D.who eat before sleep |
Daily habits like eating more healthy food would have kept millions of families from becoming bankruptif the patients had taken ways for early prevention. For example, keeping a balanced diet, such as not consuming too much animal fat and trying to have enough vegetables and fruits, seems to be quite important.
One very effective and costless way of prevention is regular exercise, which is necessary for a healthy mind and body. Regular exercise, such as running, walking, and playing sports is a good way to make people feel better or reduce stress.
In addition, health education plays a key role in improving people’s health. By giving people more information about health, countries could help people understand the importance of disease prevention and ways to achieve it. For example, knowing one’s family medical history is an effective way to help keep healthy. Information about health problems among close relatives will make them aware of what they should do to prevent certain diseases through lifestyle changes, which will work before it is too late.
However, paying more attention to disease prevention does not mean medical treatment is unimportant. After all, prevention and treatment are just two different means toward the same effect. In conclusion, we could save money on health care and treat patients more successfully if our country spends more money on health prevention and education.
小题1:What’s the best title of the passage?
A.Prevention or Education? | B.Exercise or Illness? |

A.Unable to be cured. | B.Unable to pay one’s debts. |
C.Stronger than ever before. | D.More successful than ever before. |
A.dressing warmly can prevent diseases. |
B.a balanced diet is cheaper than regular exercise. |
C.the more health education, the better. |
D.the government’s health budget should be increased. |
