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.

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.
