If so, you have some mistaken ideas about the nature of happiness. Many intelligent people still consider happiness equal to fun. The truth is that fun and happiness have little or nothing in common. Fun is what we experience during an act. Happiness is what we experience after an act. It is a deeper, more lasting emotion. Going to an amusement park or ball game, watching a movie or television, are fun activities that help us relax, temporarily forget our problems and maybe even laugh. But they do not bring happiness, because their positive effects end when the fun ends. I have often thought that if Hollywood stars have a role to play, it is to teach us that happiness has nothing to do with fun. These rich, beautiful people have constant access to glamorous parties, fancy cars, expensive homes, everything that brings "happiness". But in memoir after memoir, famous people expose the unhappiness hidden beneath all their fun -- depression, alcoholism, drug addiction, broken marriages, troubled children and extreme loneliness. Ask an unmarried man why he refuses to get married even though he finds dating to be less and less satisfying. If he's honest, he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure and excitement. Marriage has such moments, but they are not its most distinguishing features. Similarly, couples that choose not to have children are deciding in favor of painless fun over painful happiness. They can dine out whenever they want and sleep as late as they want. Couples with babies are lucky to get a whole night's sleep or a three-day vacation. I don't know any parent who would choose the word fun to describe raising children. The way people stick to the belief that a fun-filled, pain-free life equals happiness actually reduces their chances of ever achieving real... Question: In the writer's opinion, marriage _ . Options: A: means the end of fun B: leads to less sleep C: leads to raising children D: means responsibility

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: According to Dirk Behringer, his restaurant _ . Options: A: has an environment-friendly power supply B: is in great need of electricity C: serves various kinds of German food D: receives lots of customers every day

Q: Read the article and select the best answer. Article: Dogs are prone to complex emotions such as jealousy and pride, according to scientific research that sheds new light on their relationship with humans. Dogs do not like seeing their owners offering affection to other creatures, especially other dogs, and react negatively when their owners bring home new partners, the research found. Psychologists previously believed most animals lack the "sense of self" needed to experience so-called secondary emotions such as jealousy, embarrassment or guilt. These emotions are more complex than feelings associated with instant reaction such as anger, lust or joy. Dr Friederike Range, of theprefix = st1 /UniversityofVienna's neurobiology department, has shown that dogs feel intensely jealous when they spot that they are unfairly treated compared with other dogs. The dog study is the latest into several species, including cows, horses, cats and sheep, which have shown that animals are far more self-aware than we thought. Dr Paul Morris, a psychologist at theUniversityofPortsmouthwho studies animal emotions, told The Sunday Times, "We are learning that dogs, horses, and perhaps many other species are far more emotionally complex than we ever realised. They can suffer simple forms of many emotions we once thought only primates could experience. " In research among dog owners, Dr Morris found almost all of them reported jealous behaviour by their pets. The dog often tried to keep their owner away from a new lover in the early days of a relationship. Behavioural experts recommend owners keeping their dogs' routine as much as possible when a new partner or child comes along in order to prevent jealous activities from the dog such as interruptions with barking. Question: We can infer that _ . Options: A: dogs are of social animals B: dogs can be trained as a guide C: dogs have a sharp sense of smell D: primates are generally more emotional than dogs in the eyes of most people
