[EX Q]: Article: Since we are social beings, the quality of our lives depends in large measure on our interpersonal relationships.One strength of the human condition is our tendency to give and receive support from one another under stressful circumstances.Social support consists of the exchange of resources among people based on their interpersonal ties.Those of us with strong support systems appear better able to deal with major life changes and daily difficulties.People with strong social ties live longer and have better health than those without such ties.Studies over a range of illnesses, from depression to heart disease, show that the presence of social support helps people protect themselves from illness, and the absence of such support makes poor health more likely.

[EX Q]: Article: You can have your adventure and eat too at Europe's first green restaurant where traditional German food is served in a beautifully lit wooden hilltop restaurant powered by solar energy at a height of 1,025 metres among tall trees in the Black Forest. The Rappenecker Hutte is a 350-year-old farm house in south Germany which has been serving as a hikers' restaurant for several years. It was the starting point of the downhill course of the Mountain Bike World Championship (MBWC) in 1995 and is a well-known station of the Black Forest Ultra Bike Marathon (BFUBM). "People come here for adventure trips, mountain biking or hiking and stop for traditional German food. We produce all our energy from renewable sources as it is very expensive to get a power grid connection at this site," said Dirk Behringer, owner of the Rappenecker Hutte. Like the restaurant, the story of its present owner is equally amazing as Behringer, 57, left his well-paid job in 2003 to stay here with his wife. "I have traveled across the world and as I was growing old I realized I wanted to retire and live in nature. So I rented the restaurant. Since then I, along with my wife, live here in summer and we travel during winter," said the six-foot-tall man dressed in a T-shirt and shorts. Due to heavy snow during winter, the restaurant opens only for six months from April to September when it receives around 500 guests per week. The Behringer couple has employed no helper and does everything from cooking to cleaning at this hilltop restaurant which gives a picturesque view of the Black Forest. There are not many dishes on the menu for unexpected visitors. On a routine basis, there is one vegetarian dish which includes fried potatoes with dense milk cream, boiled vegetables and fresh salad. The non-vegetarian dish includes fried potatoes with pork and salad. There are also options to pick from fresh juices, hard drinks and coffee. All vegetables, fruits, dairy products and meat supplies to the restaurant come from farms in nearby villages.
Question: By mentioning such events as MBWC and BFUBM, the author intends to _ .
Options: (A) prove the restaurant has a long history (B) advise us to do more exercise (C) stress the restaurant's being unusual (D) express his fondness of the restaurant

[EX Q]: Article: How can we measure animals' emotions? A new study of animal's emotions suggests that, as in humans, emotions can tell animals about how dangerous their world is, and guide the choices that they make. The article of the study by Bristol University's professor Mike Mendl was published online. An animal living in an environment where it is often threatened by predators will develop a negative emotion or "mood", such as anxiety. However, one in an environment with plenty of opportunities to get resources for survival will be in a more positive mood state. The researchers say that these emotional states not only show the animal's experiences, but also help it decide how to make choices, especially in unclear situations. This could have good or bad results. An animal in a negative mood state will make a safety-first with a "pessimistic" response to an unclear event. For example, it considers a noise in the grass as a signal of the predator. At the same time, an animal in a positive mood state will benefit from a more "optimistic" response. It considers the noise as a signal of prey . Professor Mike Mendl, head of the Animal Welfare and Behavior Research Group at Bristol University's School of Clinical Veterinary Science said, " We can use "optimistic" or "pessimistic"decision-making as a symbol of an animal's emotional state. Recent studies by our group and others suggest that this is a _ new approach to studying a variety of animal species." "Public interest in animal welfare remains high, with widespread concern about the way in which animals are treated, used and included in society. To understand how animals should be treated, we need to better understand their emotional lives," Mike Mendl said. The researchers believe Mike Mendl's study can help them to better understand and assess an animal's emotions.
