7.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.

8.单项选择题Passage ThreeEating an apple a day doesn't keep the doctor away, but it does reduce the amount of trips you make to the drug to the drug store per year. That's according to a new study that investigates whether there'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 do contain 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.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 Apple can help cure certain diseases.
D.Apples can provide people with sufficient daily intake of energy.

9.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.

10.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. "
