Eating an apple a day doesn&39; t keep the doctor away, but it does reduce the amount of t

rips 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

We all love a hero, and rescue dogs are some of the biggest heroes of all. You will often

find them going above and beyond duty to save someone, risking--and at times losing--their lives in the process.

Rescue dogs are generally found in the Sporting and Hunting Groups, or from the traditional Herding Group. These types include the Bloodhound, Labrador Retriever, Newfoundland, German Shepherd, Golden Retriever, and Belgian Malinois--all of which are chosen for search-and-rescue duty because of their amazing physical strength, loyalty, and their tendency for mental stability.

These types also have a keen sense of hearing and smell--to better locate lost individuals—and are often able to access hard-to-reach areas. As highly trained animals, they serve in many different fields, including specialist search, snow slide rescue, dead body location, and tracking.

To overcome obstacles and succeed when performing the demanding duties of a search-and-rescue worker, a dog must display certain qualities. In addition to intelligence and strength, the dog must be swift, confident, easily trainable, adaptable, and have a high level of stamina (耐力) and endurance. A strong sense of group cooperation and an ability to engage in friendly play during "down" time is also required of search-and-rescue dogs.

A rescue dog goes through many, many hours of intensive training to be fit for duty. Training is not for the faint-hearted. Certification training can take from two to three years, working three to four hours a day, three to six days a week, often in group,team-oriented sessions.

Each search-and-rescue field requires different types of training. Rescue training, for instance, includes "air scenting"--where dogs are trained to smell the air for the victim&39; s scent (气味) and then follow the scent to the person. This ability is crucial to finding victims trapped under collapsed buildings and snow slide.

40. Rescue dogs are chosen probably because__

A.they are loyal

B.they are brave

C.they have amazing appearances

D.they have good eyesight

What does "faint-hearted" in Paragraph 5 mean?A.Courageous.

B.Cowardly

C.Energetic

D.Slow

Which ability is most important for dogs to rescue people trapped in snow?A.Sharp hearing

B.Swift movement

C.Extraordinary smelling

D.A strong memory

What is the passage mainly about?A.Selection process of rescue dogs

B.Qualities and training of rescue dogs.

C.Risks rescue dogs are faced with

D.Types of tasks rescue dogs can perform

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.

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. "
