一本好题口算题卡系列答案Most of the news in the newspapers is bad but sometimes there is a story with good news. This is one of those stories. Millions of people around the world suffer from AIDS, malaria, tuberculosis, and other serious diseases. There are medicines to treat these diseases but for people in poor countries, these medicines are too expensive to buy. When a pharmaceutical（制药的）company produces a new medicine, they receive a special license called a patent. This license means that the new medicine or drug is protected for a period of 20 years. The company that produced the drug can fix the price of the drug and no other company is allowed to produce the same drug or a copy of the drug for 20 years. At the moment, these patents operate all over the world, both in rich countries and in poor countries. The drugs companies say that they need patents so that they can get the money to pay for research to find new drugs and medicines. In rich countries people usually have enough money to pay for these drugs but in poor countries people can’t afford to buy them and cannot treat diseases like AIDS and malaria.
Last month, however, a group of experts published a report which says that patents are very bad for poor countries. The report says that drug companies do not want to find new medicines for diseases of poor people in poor countries. It says that poor countries should be allowed to buy cheap drugs without patents from other countries.
The authors of the report were lawyers, scientists and a senior director from the drug company Pfizer. Of course, the pharmaceuticals industry doesn’t agree with the report, “We need patents so that we can develop new medicines to fight disease both in the developed and developing world,” said a spokesman. But the report is the first sign that there might be a change in the patent system. This change could save millions of lives in the world’s poorest countries. This really is good news.

Writer and teacher Yin Jianli's stories and thoughts about bringing up her daughter
Yuanyuan have been a constant source of inspiration for parents over the past 16 years.
Her book, A Good Mother Exceeds Good Teachers, published by Writers Publishing House, has been a bestseller on Dangdang and Amazon's online platforms
for the past three years. The book helped Yin make the Chinese Writers' Rich List, with 4. 48 million yuan（＄710，000).
Experts say Yin's book provides practical guidance, which makes it popular among parents.
"When the majority of books are either full of bragging about（自吹自擂）the authors' children or outlining big theories that have no foundation in practice, I write books that are practical and easy to follow," Yin writes.
"For example, there was an occasion when Yuanyuan forgot to do her elementary school homework. In such a situation many Chinese parents show their anger and scold their kids,”says Yin, who made an agreement with her husband they would not overly criticize or push their daughter. Instead, Yin encouraged the daughter to make up the homework, which meant staying up until midnight. As a result, she learned to arrange her time better and did not have a harmful reaction to doing homework. Yin's principle of "no parental interference（干涉），and "giving children the opportunity to learn from their mistakes" is described in a number of real-life examples.
Readers say Yin's books improve their children's performance at school, and encourage them to develop good personalities and habits. They believe her books are not only about being good parents but also about growing as parents and individuals.
"When I'm reading books，I keep thinking about what a better personality I would have if my parents had adopted the methods Yin suggests when I was a kid，＂one reader comments in a review on Yin's online blog.

Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.
Previous studies have linked high exposure (暴露）to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中风）within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好）quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.
【小题1】The text mainly discusses the relationship between .
| A．heart problems and air quality |
| B．heart problems and exercising |
| C．heart problems and smoking |
| D．heart problems and fatty food |
| A．relatively high | B．extremely low |
| C．relatively low | D．extremely high |
| A．Eating fatty food has immediate effects on your heart. |
| B．The EPA conducted many studies on air quality. |
| C．Moderate air quality is more harmful than smoking, |
| D．Stricter regulations on pollutants should be made. |
A German study suggests that people who were too optimistic about their future actually faced greater risk of disability or death within 10 years than those pessimists who expected their future to be worse.
The paper, published this March in Psychology and Aging, examined health and welfare surveys from roughly 40,000 Germans between ages 18 and 96. The surveys were conducted every year from 1993 to 2003.
Survey respondents (受访者) were asked to estimate their present and future life satisfaction on a scale of 0 to 10, among other questions.
The researchers found that young adults (age 18 to 39) routinely overestimated their future life satisfaction, while middle-aged adults (age 40 to 64) more accurately predicted how they would feel in the future. Adults of 65 and older, however, were far more likely to underestimate their future life satisfaction. Not only did they feel more satisfied than they thought they would, the older pessimists seemed to suffer a lower ratio (比率) of disability and death for the study period.
“We observed that being too optimistic in predicting a better future than actually observed was associated with a greater risk of disability and a greater risk of death within the following decade,” wrote Frieder R. Lang, a professor at the University of Erlangen-Nuremberg.
Lang and his colleagues believed that people who were pessimistic about their future may be more careful about their actions than people who expected a rosy future.
“Seeing a dark future may encourage positive evaluations of the actual self and may contribute to taking improved precautions (预防措施),” the authors wrote.
Surprisingly, compared with those in poor health or who had low incomes, respondents who enjoyed good health or income were associated with expecting a greater decline. Also, the researchers said that higher income was related to a greater risk of disability.
The authors of the study noted that there were limitations to their conclusions. Illness, medical treatment and personal loss could also have driven health outcomes.
However, the researchers said a pattern was clear. “We found that from early to late adulthood, individuals adapt their expectations of future life satisfaction from optimistic, to accurate, to pessimistic,” the authors concluded.
【小题1】According to the study, who made the most accurate prediction of their future life satisfaction?
| A．Optimistic adults. | B．Middle-aged adults. |
| C．Adults in poor health. | D．Adults of lower income. |
| A．to fully enjoy their present life |
| B．to estimate their contribution accurately |
| C．to take measures against potential risks |
| D．to value health more highly than wealth |
| A．They will earn less money. |
| B．They will become pessimistic. |
| C．They will suffer mental illness. |
| D．They will have less time to enjoy life. |
| A．Pessimism guarantees chances of survival. |
| B．Good financial condition leads to good health. |
| C．Medical treatment determines health outcomes. |
| D．Expectations of future life satisfaction decline with age. |
