A girl became a volunteer in the activities of Deathbed Care, which meant visiting and taking care of a patient suffering from an incurable disease with days numbered. The girl was assigned to look after an old man suffering from cancer whose children lived abroad. Their living conditions were not satisfactory while the old man had a lot of savings. She was expected to comfort him and keep up his spirits. Every Saturday the girl came on time to keep him company, telling him stories. When he was having an intravenous drip , she would help massage his arms. The doctor found the patient much improved mentally. The old man began to involve himself actively in the medical treatment and he seldom shouted at others. But something that happened made the doctor uneasy and puzzled. Each time the girl left, the old man would give her some money. The doctor did nothing to interfere , unwilling to offend the old man. A month later the old man showed evident signs of decline after suffering coma a few times. When rescued from the latest coma, the old man told the doctor his last wish, "I have deep sympathy for the girl. Will you be kind enough to help her finish her studies?" But the doctor knew that her family was welloff and she had no difficulty pursuing her studies. Sometimes she even came to the hospital in her father's car. When the girl came at the weekend after the death of the old man, the doctor told her the bad news. She was very sad and burst into tears. Then she handed $ 500 to the doctor, saying, "The old man had all along thought I came to do the job because of poverty. He gave me money so that I could continue my schooling." Now he got the answer to the puzzle. In the last period of his life, the old man found it a real pleasure to be able to help a girl badly in need. What can we learn from the passage? A) The doctor told the old man the truth. B) The old man's children were wealthy. C) The girl's father encouraged her to accept the money. D) The girl didn't accompany the old man when he died.

We gather a great deal of incidental knowledge from pets.If we look after them properly we learn what they like and dislike. We do not set out to gain this knowledge purposely, but in attending to our pets we gain it by the way. It is got without our realizing it. In keeping our dogs or cats we learn about various diseases that can affect them,and the cures for these diseases.We learn how much sleep they need and what kind of food keeps them healthy. In looking after our fish we learn about the composition of water.We get to know what kinds of fish can live peacefully together and what kinds are hostile to each other.We learn that animal,fish and birds have a lot of things in common with human beings. If children keep pets their general education is helped by this kind of incidental knowledge.One little incident after another in which their pets are involved adds to their store of learning.It is a more interesting form of learning than that given in the biology lesson in school.People who keep pets should have a sense of responsibility towards them.Children,too,should be taught to be responsible.Pets are completely dependent on their owners and the owners should respond to this dependence by looking after them.Irresponsible behavior towards pets is a form of cruelty. In deciding to keep a pet we take on a task,we make ourselves responsible for providing proper food and shelter for the pet.In a crowded city like Hong Kong, where there is so little room for the exercise required by large pets,we should think _ before undertaking the responsibility of keeping one. In keeping pets,responsibility means _ . A) depending on them B) taking care of them C) writing to them D) teaching them

*Question*
Caffeine not only gives us a daily jump start, but new research suggests it also can strengthen long-term memory. According to the US Food and Drug Administration, nearly 90 percent of people worldwide consume about 200 milligrams of caffeine each day. That' s equivalent to about one strong cup of coffee a day. Writing in " Nature Neuroscience" , Johns Hopkins University researchers say their findings show that caffeine strengthens certain memories for up t0 24 hours after being taken in. " We've always known that caffeine has cognitive-enhancing effects , but its ,particular effects on strengthening memories and making them resistant to forgetting has never been examined in detail in humans, " said senior author of the paper Michael Yassa. " We re- port for the first time a specific effect of caffeine on reducing forgetting over 24 hours. " Conducting a double-blind trial, the researchers worked with a test group of people who didn't regularly consume caffeinated products. Five minutes after studying a series of images, the test subjects were given either a placebo or a 200-milligram caffeine tablet. To check the caffeine levels of their test subjects, the research team took saliva samples from them before they took their tablets and again one, three and 24 hours after- wards. Both groups of test participants ( those who took the placebo and those who took the caffeine tablet) were tested the following day to see if they could recognize the images they' d seen the previous day. The test included showing the test subjects another series of images that included some new images , those that were shown the previous day, as well as other images that were similar, but not the same as those they had viewed earlier. The researchers found that more members of the group who were given the caffeine tablets were able to correctly identify some of the new images as " similar" to previously viewed images rather than incorrectly identifying them as the same. "We also know that caffeine is associated with... During the research ,the researchers did the following things EXCEPT A) giving the test subjects placebos or caffeine tablets B) checking the caffeine levels of the test subjects C) encouraging the test subjects to drink more coffee D) showing the test subjects series of images
