Q: Read the following article and select the best answer. Article: A dog's tail can tell you a lot more than you might think. Is it wagging to the left or is it wagging to the right? "The direction of tail wagging does in fact matter,"said Giorgio Vallortigara,a professor at the University of Trento in Italy. Professor Vallortigara finds that the way the tail is wagging can tell you a lot about a dog's state of mind--whether you're a human or another dog. What's the difference between a left wag and a right wag?Professor Vallortigara and his colleagues have studied 43 dogs of various breeds -- German Shepherds,Beagles,Boxers,Border Collies and some mutts. They find that if a dog wags its tail to the left. it's feeling anxious or nervous. The reason could be an unfamiliar or dangerous situation,an unfamiliar person,or an unfamiliar and possibly threatening dog. But if the tail is wagging to the right,it means the dog is feeling relaxed and approachable. "The tail is a very important signal,"said Thomas Reimchen,a biologist at the University of Victoria in British Columbia, Canada. "There is a lot of visual information that dogs use when communicating with each other. " How did the scientists figure all this information out? They had the dogs in their study watch videotapes of other dogs. When the dog on the tape wagged its tail to the right,they say the other dogs remained calm and cool. But when the dog on the tape wagged its tail to the left,the other dogs got anxious. The researchers are still not exactly sure if the direction of tail wagging is something the dog does consciously. They suspect that it might be something the dog does without even thinking about it -- kind of like when you get goose bumps if something scares or startles you. They plan to do more research to get more information about what dogs are thinking and feeling while they're wagging. As Reimchen said,"I'm not going to be surprised if we find all sorts of really interesting processes that nobody has ever seen before. " Question: How does the passage mainly develop? - By asking and analyzing questions - By making comparisons - By following the order of time - By providing examples
A: By asking and analyzing questions

Q: Read the following article and select the best answer. Article: At primary school in New Zealand, I was introduced to a school savings account run by one of the local banks. When our money box was full, we took it to the bank and watched with pride as our coins flowed across the counter. As a reward,we could choose our next money box from a small variety, and start the whole savings routine again. Every week I watched my parents sort out the housekeeping and "make ends meet". Sometimes it was annoying to wait for things we really felt we needed. Later, as a university student, I managed on an extremely small student allowance. Students were ignored by banks then, because we were so poor, and there was no way I could have gotten credit, even if I had tried. We collected our allowance three times each year, deposited it to the best advantage and withdrew it little by little to last until the next payout of the allowance. When our daughter, Sophie, began to walk, we made a purposeful choice to encourage her to use money wisely. We often comment when the TV tells us "You owe it to yourself to borrow our money"--to whom do we really owe it? And what would happen if our income were reduced or dried up? Now, as a 12-year-old child, it's almost embarrassing to see her tight "financial policy",and wait for the unavoidable holiday sales to buy what she wants. I agree that financial education in schools is very important. But the root of the problem lies with us and the way we behave as role models to those who follow. Question: What did the author learn from her parents? - How to become a banker. - Where to open a savings account. - Where to choose a money box. - How to make ends meet.
A: How to make ends meet.

Q: Read the following article and select the best answer. Article: Every day, Daisy wakes up next to a man, who has to convince her they are married. When she expresses doubt, he takes out a photo album and shows her pictures of their wedding 13 years ago. Only then does _ Daisy accept that she has been married, and that everything he has told her is true. The lady's condition was caused by brain injuries suffered in two road accidents, a motorbike crash in 1985 and a car accident in 1990. Daisy can recall everything up to 1994, but since then everything that happens on one day is forgotten the next day. She has no day-today memory after the car crash. And it is not just loved ones Daisy struggles with. She uses hundreds of notes and reminders on her mobile phone's calendar to keep her informed of appointments and everyday duties. Anything she has done or anyone she has met must be logged for future reference. And on the rare occasions when she takes the risk of going out of her home alone, she has to be armed with navigation programmed with her address. There are some benefits, however. There is no such thing as a repeat on TV and every joke is funny, because it seemed she has heard it the first time."It's like I am living the same day, day after day, said Daisy, who does voluntary work at a charity for people with disabilities three days a week. Dr Peter Nestor said Daisy was suffering from anterograde( , ) amnesia. He added, "It is reasonably rare, but it does exist. You are able to carry out daytoday things, and don't forget how to do certain things like speaking. But if someone was to ask you what you did yesterday, you wouldn't have a clue." Question: How did Daisy's family help remind her? - By taking her to the hospital - By telling her jokes. - By showing her old photos and pictures. - By persuading her to recall the car crash.
A: By showing her old photos and pictures.

Q: Read the following article and select the best answer. Article: Is language, like food, a basic human need? Judging from the extreme experiment of Frederick in the 13th century, it may be. Hoping to discover what language a child would speak if he heard no mother tongue he told the nurses to keep silent. All the babies died before the first year. But clearly there was more than language deprivation (,). What was missing was good mothering. Without good mothering, in the first year of life especially, the ability to survive is seriously affected. Today no such extreme deprivation exists as that ordered by Frederick. Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to signals of the baby, whose brain is programmed, to mop up language rapidly. There are critical times, it seems when children learn more rapidly. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again. Linguists suggest that speech milestones are reached in a fixed order and at a constant age, but there are cases where speech has started late in a child who eventually turns out to be of high IQ. Recent evidence suggests that a baby is born with the ability to speak. What is special about man's brain, compared with that of the monkey, is the complex system which enables a child to connect the sight and feel of, say, a teddy bear with the sound pattern "teddy bear". But speech has to be developed, and this depends on interaction between the mother and the child, where the mother recognizes the signals in the child's babbling, clinging, grasping, crying, smiling, and responds to them. Insensitivity of the mother to these signals reduces the interaction because the child gets discouraged and sends out only the obvious signals. Sensitivity to the child's nonverbal signals is basic to the growth and development of language. Question: Frederick's experiment was extreme because _ . - he wanted to prove children are born with ability to speak - he wanted his nurses to say another language - he was unkind to the nurses - he ignored the importance of mothering to the babies
A: he ignored the importance of mothering to the babies
