Read the article and select the best answer. Article: Tigers are among the most admired and most feared animals in the world . When we think of a tiger, we think of danger. We think of the big teeth and large feet of it. We also think of beauty. The tiger is a hunter that hunts alone. In fact , tigers are probably better than any other land mammal at catching large animals without help. Even so, the life of this big-game hunter isn't easy. Finding food can be difficult, especially for a tiger that is old or weak. Most of the animals it tries to attack get away. A tiger sometimes goes weeks without eating. When that happens, it may hunt animals that can be dangerous even for a tiger. When they are in a bad situation, some tigers may even attack humans. But in fact, tigers kill very few people each year. Most tigers run away when they see people. What tigers have done to people can't compare to what people have done to tigers. Over the last 200 years, we have almost killed tigers in the wild . Today, the tiger is one of the most endangered animals on Earth. A tiger may live 20 years or more, if it is not disturbed by humans. Female tigers usually live longer than male tigers, because the males live more dangerously. It isn't easy for people to tell a male from a female unless the female happens to be with her babies.Only females take care of the young. The big difference between males and females is size. Male tigers are much bigger. Tigers are big eaters. In a single year, one tiger must eat about 70 deer or other large animals. That is one reason why tigers hunt alone. If they lived in big groups, they could never find enough animals to feed them all. Question: According to the passage, why do tigers hunt alone? Options: A: They can run faster hunting alone. B: They can't get along well with other tigers. C: They can hide themselves easily in this way. D: They can't find enough animals to share with other tigers.

Read the article and select the best answer. Article: Everybody hates it, but everybody does it. A recent report said that 40%of Americans hate tipping. In America alone, tipping is a $16 billion-a-year industry. Consumers acting politely ought not to pay more than they have to for a given service. Tips should not exist. So why do they? The common opinion in the past was that tips both rewarded the efforts of good service and reduced uncomfortable feelings of inequality. And also, tipping makes for closer relations. It went without saying that the better the service, the bigger the tip. But according to a new research from Cornell University, tips no longer serve any useful function. The paper analyzes numbers they got from 2,547 groups dining at 20 different restaurants. The connection between larger tips and better service was very weak. Only a tiny part of the size of the tip had anything to do with the quality of service. Tipping is better explained, by culture than by the money people spend. In America, the custom came into being a long time ago. It is regarded as part of the accepted cost of a service. In New York restaurants, failing to tip at least l5% could well mean dissatisfaction from the customers. Hairdressers can expect to get l5%-20%, and the man who delivers your fast food $2. In Europe, tipping is less common. In many restaurants the amount of tip is decided by a standard service charge. In many Asian countries, tipping has never really caught on at all. Only a few have really taken to tipping. According to Michael Lynn, the Cornell papers' author, countries in which people are more social or outgoing tend to tip more. Tipping may reduce anxiety about being served by strangers. And Mr. Lynn says, "In America, where people are expressive and eager to mix up with others, tipping is about social approval. If you tip badly, people think less of you. Tipping well is a chance to show off." Question: Among the following situations, in your opinion, who is likely to tip most? Options: A: A Frenchman just quarreled with the barber who did his hair badly in New York. B: An American just had a wonderful dinner in a well known restaurant in New York. C: A Japanese businessman asked for a pizza delivery from a Pizza Hut in New York. D: A Chinese student enjoyed his meal in a famous fast food restaurant in New York.

Ques: Read the article and select the best answer. Article: The Red Cross is an international organization which cares for people who are in need of help. A man in a Paris hospital who needs blood, a woman in Mexico who was injured in an earthquake, and a family in India that lost their home in a storm may all be aided by the Red Cross. The Red Cross exists in almost every country around the world. The world Red Cross organizations are sometimes called the Red Crescent, the Red Mogen Daid, the Sun, and the Red Lion. All of these agencies share a common goal of trying to help people in need. The idea of forming an organization to help the sick and wounded during a war started with Jean Henri Dunant. In 1859, he observed how people were suffering on a battlefield in Italy. He wanted to help all the wounded people regardless of which side they were fighting for. The most important result of his work was an international treaty called the Geneva Convention . It protects prisoners of war, the sick and wounded, and other citizens during a war. The American Red Cross was set up by Clara Barton in 1881. Today the Red Cross in the United States provides a number of services for the public, such as helping people in need, teaching first aid and providing blood. Question: We may draw a conclusion that _ during a war. Options: A: the Red Cross only protects the wounded B: the Red Cross only helps prisoners of war C: the Red Cross only helps citizens D: the Red Cross helps all the people in need no matter which side they are fighting for

Ques: Read the article and select the best answer. Article: Getting too little sleep or not spending enough time in rapid eye movement(REM) sleep is connected with being overweight among children, according to a new study. For three nights, researchers studied the sleep patterns of 335 young people, aged 7 to 17. They looked at total sleep time, time spent in REM, time it took to fall asleep. Body-mass index was checked at the start of the study, and 45 persons in the research were overweight, while 49 were at risk of becoming overweight. Compared to normal-weight children, those who were overweight slept about 22 minutes less per night and didn't sleep as well as them, which means shorter REM sleep, less eye activity during REM sleep, and a longer wait before the first REM period. After more research, the researchers concluded that one hour less of total sleep was connected a double increased risk of being overweight. One hour less of REM sleep was connected with a three times increased risk. Although the reasons are still being researched, the relationship between short sleep duration and overweight may be the result of behavioral and biological changes, which are caused by sleep loss, wrote Dr. Xianchen Liu of the Western Psychiatric Institute and Clinic in Pittsburgh and his colleagues. They explained that sleep loss causes changes in hormone levels that may have an effect on hunger, and less sleep also means a person has more waking hours in which to eat. Sleep loss also leads to tiredness the following day, which may lead to less physical activity and fewer calories burned. Question: What is the best title for this passage? Options: A: Researchers find why children become overweight. B: Kids who are overweight are in need of more sleep. C: Children who sleep poorly are at risk of being overweight. D: Researchers find ways to prevent children from becoming overweight.
