It is easy to lose patience with science today． The questions are pressing: How dangerous is air pollution? What about low-level radiation? When will that horrible earthquake strike California? And why can't we predict weather better? But the evidence is often described as "uncertain", forcing scientists to base their points of view almost as much on intuition（直觉）as on science．
When historians and philosophers of science listen to these questions, some conclude that science may not be able to solve all these problems any time soon． The unknowns can grow into riddles that are impossible to solve． Because of the unstable and changing state of the earth's atmosphere, for example, scientists have struggled for centuries to predict the weather with precision（精确） but failed．
The case is different for scientists of astronomy． For example, they think that the gravitational force of a nearby space vehicle, though tiny, is able to change the path of a much larger planet if the vehicle spends enough time close to it． With the aid of Newton's laws of gravitational attraction, ground controllers can predict the path of a planetary probe （探测仪）-or satellite-with incredible accuracy． They do this by calculating the gravitational force from each of the passing planets until the probe speeds beyond the edge of the solar system．A much more difficult task is to calculate what happens when two or three times of such force pull on the probe at the same time． Such procedures can, of course, be very difficult, but for experiments, they are effective．
This range of questions-from simple problems to those impossibly complex-has resulted in nicknames for various fields of study: "soft" sciences and " hard " sciences．“Soft” sciences admit a great degree of uncertainty． Academicians tend to judge fields such as sociology, psychology, and political science as “soft” because they are assumed to be understandable, of unnecessary mathematical accuracy, and concerned with everyday affairs such as interpersonal relationships． However, "hard" sciences, such as astronomy and chemistry, are said to offer precise answers． Precise definitions for "hard" sciences vary, but the characteristics of "hard" sciences include: producing testable predictions; performing controlled experiments; relying on quantifiable data and mathematical models; a high degree of accuracy and objectivity; and generally applying a pure form of the scientific method

Do you want to live with a strong sense of peacefulness, happiness, goodness, and self-respect? The collection of happiness actions broadly categorized as “honor” help you create this life of good feelings.
Here is an example to show how honorable actions create happiness.
Say a store clerk fails to charge us for an item. If we keep silent, and profit from the clerk’s mistake, we would drive home with a sense of mean excitement. Later we might tell our family of friends about our good fortune. On the other hand, if we tell the clerk about the uncharged item, the clerk would be grateful and thank us for our honesty. We would leave the store with a quiet sense of honor that we might never share with another soul.
Then, what is it to do with our sense of happiness?
In the first case, where we don’t tell the clerk, a couple of things would happen. Deep down inside we would know ourselves as a type of thief. In the process, we would lose some peace of mind and self-respect. We would also demonstrate that we cannot be trusted, since we advertise our dishonor by telling our family and friends. We damage our own reputations by telling others. In contrast, bringing the error to the clerk’s attention causes different things to happen. Immediately the clerk knows us to be honorable. Upon leaving the store, we feel honorable and our self-respect is increased. Whenever we take honorable action we gain the deep internal rewards of goodness and a sense of nobility.
There is a beautiful positive cycle that is created by living a life of honorable actions. Honorable thoughts lead to honorable actions. Honorable actions lead us to a happier existence. And it’s easy to think and act honorably again when we’re happy. While the positive cycle can be difficult to start, once it’s started ,it’s easy to continue. Keeping on doing good deeds brings us peace of mind, which is important for our happiness.According to the passage, the positive action in the example contributes to our ______.
| A．self-respect | B．financial rewards |
| C．advertising ability | D．friendly relationship |
The author thinks that keeping silent about the uncharged item is equal to ______.
| A．lying | B．stealing | C．cheating | D．advertising |

| B．offering advice to the clerk |
| C．asking the clerk to be more attentive |
| D．reminding the clerk of the charged item |
How will we feel if we let the clerk know her mistake?
| A．We’ll be very excited. |
| B．We’ll feel unfortunate. |
| C．We’ll have a sense of honor. |
| D．We’ll feel sorry for the clerk. |

It seems like every day there's some new research about whether our favorite drinks are good for us. One day, science says a glass of red wine a day will help us live longer. The next day, maybe not. It seems journalists are pretty interested in wine research and the same might be said for coffee. Now there's been a lot of research into whether coffee's good for our health "the results have really been mixed"，admits Neal Freedman who led the coffee study and published his findings in a medical journal recently. "There's been some evidence that coffee might increase the risk of certain diseases and there's also been maybe more recent evidence that coffee may protect against other diseases as well".
Freedman and his colleagues undertook the biggest study yet to look at the relationship between coffee and health. They analyzed data collected from more than 400，000 Americans ages 50 to 70 participating in the study. "We found that the coffee drinkers had a modestly lower risk of death than the non-drinkers， he said. Here's what he means by "modestly": those who drank at least two or three cups a day were about 10 percent or 15 percent less likely to die for any reason during the 13 years of the study when the researchers looked at specific causes of death, coffee drinking appeared to cut the risk of dying from heart disease, lung disease injuries, accidents and infections.
Now, Freedman stressed that the study doesn't prove coffee can make people live longer .A study like this can never prove a cause-and-effect relationship. All it can really do is to point researchers in the right direction for further investigation. And even if it turns out that coffee is really good for you, scientists have no idea why.According to the first paragraph，reporters would like to know the research findings of_______.

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.

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.
