Eating an apple a day doesn&39; t keep the doctor away, but it does reduce the amount of trips you make to the drug store per year. That &39; s according to a new study that investigates whether there&39; s any truth in the old saying.

A team of researchers led by Dr Matthew Davis, of the University of Michigan School of Nursing,asked 8,399 participants to answer survey questions about diet and health. A total of 753 were apple eaters, consuming at least 149g of raw apple per day. The remaining 7, 646 were classed as non-apple eaters. When both groups answered questions on trips to the doctor and trips to the drug store per year,the apple eaters were found to be 27% less likely to visit the druggist for drugs.

Trips to the doctor were not significantly affected by apple consumption, though. "Evidence does not support that an apple a day keeps the doctor away. However, the small number of US adults who eat an apple a day does appear to use fewer prescription medications," the study concludes.

Apple eaters were also found to be less likely to smoke and be more likely to have a higher educational attainment than non-apple eaters. While apples do not compete with oranges, they docontain some immune (免疫的) system-increasing vitamin C, which may be why apple-eaters visit the druggist less. With over 8mg of vitamin C per medium-sized fruit, an apple can provide roughly 14% your daily recommended intake.

Previous studies have also linked apple consumption to a lower risk of Type 2 diabetes (二型糖尿病) ,improved lung function and a lower risk of colon (结肠) cancer.

44. How many non-apple eaters answered survey questions in the research?

A.149

B.7,646

C.753

D.8,399

What is the conclusion of the study?

A.Apple consumption has greatly reduced US adults' trips to the doctor

B.An apple a day does keep the doctor away

C.Apples are far more nutritious than oranges

D.A small number of US adult apple eaters tend to take less medicine

What can we learn from the passage?

A.Apples are better than oranges

B.Apples do have some vitamin C to increase the immune system

C.Apples can help cure certain diseases

D.Apples can provide people with sufficient daily intake of energy

What can be described as the writing style of this passage?

A.Objective

B.Creative

C.subjective

D.persuasive

Debate is a valuable way to practise communicating. It can also bring long-lasting rewards,especially for people working with Western businesses. The main activity of debate is presenting one&39; s opinion and suppmting it with evidence,such as statistics or facts. It is a way of persuasive communication.

Charles Lebeau helped create the "Discover Debate" method. He says debate is important to understanding how people communicate in Western business. Successful debaters learn how to give their opinkm,reasans and support. "What we are trying to do is to develop a kind of thinking or approach to discussion and how to interact (交流) with someone else&39; s opinion, rather than brush their opinion aside. "

Debate skills are also important in selling a product, he says. In that situation, the judges are the customem. "So on Monday, for example, one company may come in and present their case to the customer and they" ll make as strong a ease as they can. On Tuesday, the next day, another company will come in and present their ease to the customer. Usually the party that can present the strongest case wins” Debate also strengthens critical thinking. In other words, it helps students learn to ask questionsand try to understand someone&39; s reasons and evidence.lift-.

Lebeau points out that successful debaters learn to listen carefully to what other people are saying. Then, they look for the weak points in someone else&39; s opinion or argument. He says debate teaches a systematic way of questioning.

Successful debaters also learn to think from someone else&39; s point of view. Mr. Lebeau says debate can help broaden the mind. "There&39; s an expression in English : don&39; t criticize another person before you have walked in their shoes. I think the wonderful thing about debate is, it puts us in another person&39; s shoes. "

36. According to Paragraph 1 ,what is the purpose of debate?

Sometimes I scratch my head when I read about the government&39; s efforts to improve schools:new standards and tests to be applied, strict teacher evaluations, and threats of school closures and job losses. They frighten the school employees, not to mention the students. Instead of making people unable to solve problems or try new ideas--which is what fear does to us--research on school reform. strongly suggests that policy-makers should encourage school leaders to take a more humane approach. In their study on the reform. efforts of twelve Chicago public schools, Bryk and Schneider found that enabling positive social relationships between the adults was the key to successful school improvement and that trust was at the heart of those relationships.

Trust in schools comes down to one thing:psychological safety or safety to speak one&39;s mind,to discuss with openness and honesty what is and isn&39; t working,to make collective decisions.

Yet this kind of safety doesn&39; t come easily to schools. According to Bryk and Schneider, the adults in school rely on each other to do their jobs correctly and with integrity (正直). The challeage is that our expectations are very diverse based on our unique backgrounds.

At one school where I taught, each teacher had different expectations about how much effort teachers should put into their work--a big difference between the teachers who left af~the last bell and those who worked into the evening. And when expectations are uncoasci or unspoken, it becomes impossible for others to live up to them.

We also make assumptions about the intentions behind a person&39; s behavior. As we all Imam,assumptions are often wrong. For example, parents and teachers my think the principal taml particular decision based on his career advancement rather than hat" s best for the studeata. don&39;t feel psychologically safe to question our assumptions and e~aecmtiatm, trust itiea am the window and our relationships suffer.

48. According to Paragraph 1,why does the author scratch his head?

A.Because he doesn’ t know what to do once schools are closed

B.Because he is not sure about the practicability of those new tests

C.Because he is concerned that many teachers will lose their jobs

D.Because he is not in favor of the government’ s reform efforts

According to Bryk and Schneider, what was most important for successful school improvemt?

A.New standards and tests in schools

B.Positive social relationships

C.Strict teacher and student evaluations

D.Assistance of the government

What is meant by trust in school?

A.Freedom to express one' s views

B.Extra effort teachers put into their work

C.Independence of the teachers in schools.

D.Unconscious and unspoken expectations

What does the author say about the assumptions made about the intentions behind a person's behavior?

A.They should be trusted

B.They are often bold

C.They are often incorrect

D.They should be encouraged

An interesting project called Blue Zones is recording the lifestyle. secrets of the communities with the highest, hest concentrations of centenarians in the world.

The people in the five regions in Europe, Latin America,Asia and the US that live to be 100 have a lot going for them. Genes probably play a small role, but these folks also have strong social ties ,tightly-knit families and lots of opportunities to exercise.

As we were examining the dietary secrets of the Blue Zones, as described in author Dan Buettner" s latest book, The Blue Zones Solution, we were struck by how essential tea drinking is in these regions. In fact, Buettner&39; s Blue Zones Beverage Rule--a kind of guideline summarized from his 15 or so years of studying these places--is:" Drink coffee for breakfast, tea in the afternoon, wine at 5 p. tm"

Science has plenty to say about the healthful virtues of green tea. Researchers are most enthusi- astic almt the components in green tea, as well as foods like cocoa. Why might they help so many Okina~vans in Japan break 1007 Some components in green tea can lower the risk of stroke,heart disease attd several cancers. One review study also found that drinking green tea can slightly improve metabolism (新陈代谢).

If you find yourself on the island of Ikaria, the Greek Blue Zone in the middle of the Aegean, you won&39;t be offered any tea made with tea leaves. Instead, Ikarians typically make their daily cup of tea with just one fresh herb that they have picked themselves that day--either rosemary, wild sage,oregano,nmrjotmn,mint or dandelion,all plants that may have anti-inflammatory (消炎的) properties, which may help lower blood pressure. This could explain Ikaria&39; s very low dementia (痴呆) rate,since high blood pressure is a risk factor for the disease.

52. What does the underlined word "centenarians" in Paragraph 1 refer to?

A.People who have secret lifestyles

B.People who enjoy physical exercise

C.People who are one hundred years old or older

D.People who carry the gene for being slim

What may the tea Ikarians drink daily help?

A.To improve metabolism

B.To lower blood pressure

C.To lower life stress

D.To improve social relationships

According to Paragraph 3 ,what is the recommended time for tea drinking?

A.In the morning

Here&39;s a familiar story. You&39;re sitting at the dinner table with a furry, four-legged friend scratching at your feet. When you look down, those cute eyes are almost impossible to resist.

What is it about a dog&39;s gaze that makes it so charming? A new study by Japanese scientist Miho Nagasawa seems to have found the answer, and it has to do with something called the cuddle(爱抚)chemical.

The cuddle chemical has another, more scientific name: oxytocin. Oxytocin is a substance in the blood that encourages bonding. Levels of oxytocin increase, for example, when a mother feeds her newborn baby. According to Nagasawa&39;s study, the same is true when we look deeply into the eyes of a dog.

The results of this study can tell us a lot about the history of the bond between humans and dogs. It all started somewhere tens of thousands of years ago. Scientists believe that wolves used to follow humans who were hunting large animals. The wolves would eat the food left behind by the humans.

Humans realized that they could use the wolves to help with the hunt, and eventually both species began to work together toward survival.

Over time, the wolves that interacted with the humans began to change. They became more loyal to their human partners. The wolves and humans started to depend on each other and bond with each other. These changes are what caused some of the wolves to turn into what we now know as dogs, a new specie^ evolved to better survive in their environment.

This process depended a great deal on the bond humans formed with them. And according to Nagasawa&39;s study, this bond was formed with the help of oxytocin, the cuddle chemical.

11. What do we know about oxytocin?

A.It regulates blood flow

B.It promotes bonding

C.It is in the human gene

D.It is good for health

When we look deeply into a dog's eyes, the levels of our oxytocin ____.

A.reduce over time

B.go either up or down

C.are on the rise

D.remain unchanged

At the beginning wolves followed humans to ____.

A.eat the food left by humans

B.guard against large animals

C.take humans for food

D.hunt large animals together

Over time some wolves turned into dogs ____.

A.due to their loyalty

B.due to the changing environment

C.for better survival

D.for better cooperation

What does Nagasawa9s study aim to do?

A.Explore the role of human-wolf partnership

B.Show the characteristics of the cuddle chemical

C.Explain the bond between humans and dogs

D.Understand the evolution of species

Directions Facial expressions carry meanings that are partly determined by culture. For example, many Japanese do not show their emotions as freely as Americans do, so teachers in the United States sometimes have trouble knowing whether their Japanese students understand and enjoy their lessons.

Another example is the smile. As a common facial expression, it may show affection, convey politeness, or disguise(掩饰) true feelings. But in different cultures. smiles have different meanings. Many people in Russia consider smiling at strangers in public to be unusual and even a suspicious behavior.Yet many Americans smile freely at strangers in public places, for American culture a smile is typically an expression of pleasure.

Therefore some Russians believe that Americans smile in the wrong places; some Americans believe that Russians don&39; t smile enough. In Southeast Asian cultures, a smile is frequently used to cover emotional pain or embarrassment. Vietnamese people may tell the sad story of how they had to leave their country but end the story with a smile.
