Read the article and select the best answer. Article: "Children should not be left unsupervised to play with a dog." say experts in this week's British Medical Journal. Their advice is part of a review aimed at doctors who deal with dog bites. "Dog bites and maulings are a worldwide problem, particularly in children." write Marina Morgan and John Palmer. Every year 250,000 people who have been bitten by dogs attend minor injuries and emergency units in the United Kingdom, and half of all children are reportedly bitten by dogs at some time, boys more than girls. Accurate death figures are difficult to obtain, but in the past five years, two to three cases a year have made news headlines. Based on the latest medical evidence, _ advise doctors how to examine and treat a patient presenting with a dog bite. They discuss the risk of infection and when to refer to specialist care. For travelers bitten abroad, they suggest assessing the risk of rabies . In terms of prevention, they suggest that children should be taught to treat dogs with respect, avoid direct eye contact, and not tease them. They should be taught not to approach an unfamiliar dog; play with any dog unless under close supervision; run or scream in the presence of a dog; pet a dog without first letting it sniff you; or disturb a dog that is eating, sleeping, or caring for its babies. "Dog owners also need to change their behavior", says Rachel Besser, a children's doctor and lifetime dog owner, in an article. "It is clear that not all dog owners appreciate that children should not be left unsupervised with a dog", she says. Just as some parents are obliged to take parenting classes, she would like to see compulsive classes for expectant dog owners to teach them about the responsibilities of dog ownership. Educational programs are also needed to teach children about some precautionary behaviors around dogs. Finally, she would like to see animal doctors advising dog owners about bite prevention, and doctors promoting bite prevention when treating patients who have been bitten by dogs. Question: To avoid dog bites, a child should be taught to _ . Options: A: have direct eye contact B: approach an unfamiliar dog C: run or scream in the presence of a dog D: leave a dog feeding itself

It is likely that your living room will have a television set and a video, and your kitchen a washing machine and a microwave oven. Your bedroom drawers will be filled with almost three times as many clothes as you need. You almost certainly own a car and possibly a home computer, holiday abroad at least once a year and eat out at least once a week. Now, perhaps, more than ever before, people are wondering what life is all about, and what it is for. Seeking material success is beginning to trouble large numbers of people around the world. They feel that the long-hours work culture to make more money to buy more things is eating up their lives, leaving them very little time or energy for family or pastimes. Many are turning to other ways of living and _ is one of them. Six percent of workers in Britain took the decision to downshift last year. One couple who downshifted is Daniel and Liz. They used to work in central London. He was a newspaper reporter and she used to work for an international bank. They would go to work by train every day from their large house in the suburbs , leaving their two children with a nanny . Most evenings Daniel wouldn't get home until eight or nine o'clock, and nearly twice a month he would have to fly to New York for meetings. They both earned a large amount of money but began to feel that life was passing them by. Nowadays, they run a farm in the mountains of Wales, "I always wanted to have a farm here," says Daniel, "and we took almost a year to make the decision to downshift. It's taken some getting used to , but it's been worth it . We have to think twice now about spending money on car repairs and we no longer have any holidays. However, I think it's made us stronger as a family, and the children are a lot happier." Liz, however, is not quite sure. "I used to enjoy my job, even though it was hard work and long hours. I'm not really a country girl, but I suppose I'm gradually getting used to looking... Question: When Daniel was a reporter, he _ . Options: A: lived in central London B: disliked his job C: missed his children D: was well paid

Q: Read the article and select the best answer. Article: With the new year coming, a new website was set up to offer ringtones of the sounds of dozens of rare and endangered species from around the globe. The Center for Biological Diversity started offering free wildlife ringtones for cellphones a year ago to educate people about the _ of the animals, and the campaign enjoyed such success that the environmental group has collected more ringtones and added them to its website for this year. The group plans to release a kind of new ringtones each month, including the sounds of the African elephant and the emperor penguin of the Antarctic, said Peter Galvin, the group's conservation director. "We've hit the 100,000th download in over 150 countries," Galvin said Wednesday in a telephone interview. "It's pretty interesting. We didn't realize how much of an international hit it would become." The response, he said, reinforces the worldwide movement to save endangered and rare species. Available ringtones include the howl of an endangered Mexican gray wolf, the bellows of an Arctic beluga whale and the calls of dozens of other mammals, birds and reptiles. Website visitors can also get cellphone wallpaper and facts for each of the species. And later this year, the website will be available in Spanish and more ringtones from species in Latin America will be added, Galvin said. Question: What would be the best title for the passage? Options: A: Ringtones are popular with cellphone users B: New wildlife ringtones released in a website C: New strange ringtones enjoy great success D: A new way to protect wildlife
A: B

*Question*
Read the article and select the best answer. Article: It is difficult to imagine what life will be like without memory. The meanings of thousands of everyday perceptions(, ), the bases for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory. Memory can be defined as the capacity to keep information available for later use. It includes not only "remembering" things like arithmetic or historical facts, but also involves any change in the way an animal typically behaves. Memory is involved when a rat gives up eating grain because he has sniffed something suspicious in the grain pile. Memory is also involved when a six-year-old child learns to swing a baseball bat. Memory exists not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices from storing data for later use. It is interesting to compare the memory-storage capacity of a computer with that of a human being. The instant-access memory of a large computer may hold up to 100,000 "words"--ready for instant use. An average prefix = st1 /U. S. teenager probably recognizes the meaning of about 100,000 words of English. However, this is but a fraction(, ) of the total amount of information which the teenager has stored. Consider, for example, the number of faces and places that the teenager can recognize on sight. The use of words is the advanced problem-solving intelligence of human beings. A large part of a person's memory is in terms of words and combinations of words. Question: The comparison made between the memory capacity of a large computer and that of a human being shows that _ . Options: A: the computer's memory has a little bigger capacity than a teenager's B: the computer's memory capacity is much smaller than an adult human being's C: the computer's memory's capacity is much smaller even than a teenager's D: both A and B
