Also, a Microsoft home doesn’t just warn you when you’re out of m ilk—it can send you a fresh gallon.But are these innovation(创新）just magic, or are they really coming soon to a neighborhood near you? To find out, US News asked some experts to get their opinions about the home of the near future. Here’s a look at the inn ovations.A great number of buildings filled with units look the same. The coming years, however, will give way to a personalized approach(个性化手段）to home construction (住宅建设). The houses will be an instrument of self-expresion. “The successful builders will be the ones that figure out how to change their production model enough to make the buyers feel like they are really getting something that is designed for them, not just a model,” says Kermit Baker, the chief economist(首席经济学家）at the American Institute of Architects.Future home will probably shrink. “We will be building smaller but smarter houses, says Ed McMahon, a senior resident fellow(高级研究员) at the Urban Land Institute. “Instead of having a room for just one use, consumers will demand homes that make b etter use of space,” says Susanka, whose best-selling book, The Not So Big House, has a great influence in home design. Seldom-used quarters, such as dining and living rooms, will be replaced with space that can serve both functions. “The goal of his ‘righ t-size, home is to fit its owners like a specially cut suit rather than a jacket you buy in a store,” says Susanka.1．Why does the writer mention a dream home and a Microsoft home?A．To tell us something about future houses.B．To tell us that technology develops fast.C．To tell us what kind of house to buy.D．To lead to the topic of the passage.2．According to the third paragraph, future houses will __________.A．be mass-produced (大量生产）B．have a lot of things in commonC．express the owners9 personalities (个性)D．be designed by the owners themselves3．The underlined word “shrink” in the last paragraph means __________.A．become cleaner B．become smallerC．become brighter D．become more comfortable4．Smarter houses in the last paragraph refer to houses that _________.A．can warn you when you’re out of milkB．have very advanced furnitureC．can make better use of spaceD．have a room for every use5．What is this passage mainly about?A．Some experts, opinions about future houses.B．The writer’s ideas about future houses.C．What life in the future will be like.D．The development of houses.B14、Only humans speak using words. But all kinds in the animal world can communicate in one way or another. Maybe you have heard about the way bees dance around to send messages to each other and the way dogs bark in different ways to give warnings, to be friendly or to be playful. But did you know about infrasonic communication used by elephants? This is how it works:Humans hear low sounds like thunder rumbling in the sky. But we don’t hear sounds lower than this. However, animals such as elephants and hippos can hear much lower sounds than humans can. And what’s more, they can make those low sounds as well, and they use them to communicate with each other. This is known as infrasound.The amazing thing about infrasound is that it travels over several kilometers. Higher-level sounds like the one people can hear, don’t travel well through walls, leaves, trees and so on, which is why we can’t hear sounds from more than 100 meters away. But infrasound is much stronger and things like grass and trees have no influence on it. Therefore, it can travel much further. Elephants can hear infrasonic calls from four kilometers away!There have been reports of people watching groups of elephants feeding or resting and then the elephants suddenly all stopped what they were doing for no reason at all. They obviously heard a warning call from a long way away, but the people didn’t hear a sound. In places like a zoo or wildlife park where you can get nearer to animals, it is a bit easier to sense when infrasonic sounds are made. When you stand near mother elephants with their babies in a zoo, you may notice a slight rumbling in the air every few minutes—not loud or strong, but clearly noticed. This is infrasoniccommunication—the mother elephants “talking” to their babies.1．Why does the writer mention bees and dogs in Paragraph1?A．Because they use infrasonic communication.B．Because they communicate like the elephants.C．Because they are examples of animal communication.D．Because people want to learn how they communicate.2．Which of the following is TRUE abou t ‘infrasound’?A．Humans can hear infrasound easily.B．It travels nearly several kilometers.C．It sounds low but can’t travel very far.D．It travels well through walls, leaves and so on.3．In places like zoos, ________.A．elephants don’t need to make infra sonic soundsB．it is easier for elephants to make infrasonic soundsC．mother elephants don’t let people stand near their babiesD．humans can easily sense infrasonic sounds when they are made4．Which would be the best title for the passage?A．Talking to humans B．Talking to animalsC．Playing with humans D．Playing with elephantsC15、A priest（牧师）had a cat that climbed up a tree in his backyard and then was afraid to come down. The priest persuaded(劝说), offered warm milk, etc. The kitty would not come down. The tree was not strong enough to climb, so the priest decided that if he tied a rope to his car and drove away so that the tree bent（弯曲）down, he could then reach up and get the kitty. He did so, checking his progress in the car again and again, then work out if he went just a little bit further, the tree would be bent enough for him to reach the kitty. But as he moved a little further forward, the rope broke.The tree went “boing!” and the kitty at once sailed through the air —out of sight. The priest felt terrible. He walked all over the neighborhood asking people if they’d seen his kitty. Nobody had seen a lost kitty.So, he prayed(祈祷), “God, I just give this kitty to your keeping,” and went on about his business.Several days later he was at the grocery store, meeting one of his church（教堂）members. He happened to look into her shopping cart and was amazed to see cat food. Now this woman was a cat hater and everyone knew it, so he asked her,“Why are you buying cat food when you hate cats so much?”She replied, “You won’t believe this,” and told him how her little girl had been begging her for a cat, but she kept refusing. Then a few days before, the child begged again, so the Mom finally told her little girl, “Well, if God gives you a cat, you can k eep it. ” She told the priest, “I watched my child go out in the yard, get on her knees, and ask God for a cat. You won’t believe this, but I saw it with my own eyes. A cat suddenly came flying out of the blue sky, with its paws spread out, and landed righ t in front of her. ”1．The priest drove his car to bend the tree in order to __________.A．get his kitty down from the tree B．persuade his kitty to come downC．offer the kitty some warm milk D．see if the rope was strong enough2．The underlined sentence probably means that the priest __________.A．was happy he didn’t have to care for the kittyB．hoped his neighbors would look after his catC．thought his kitty might be lost or killedD．didn’t want to see his kitty any more3．Why was the priest amazed when he saw the woman had bought much cat food?A．Because he couldn’t imagine she had her own cat.B．Because the woman was his church member.C．Because he thought she would live on cat food.D．Because he knew clearly she didn’t like a cat.4．Who gave the girl a cat?A．God B．His church member C．The priest D．His neighbour5．Which may be the best title of this passage?A．A flying cat B．A lucky girlC．God sent her a cat D．An unlucky priestD16、A young man entered the last interview of a company. The director found the young man’s academic grade were very good.“Did you get any scholarships(奖学金) in school?” The director asked. “None.” The young man answered.“Was it your father who paid for your school fees(学费)?” the director asked. “My father passed away when I was one year old, so it was my mother who paid for my school fees.” the young man answered.“Where did your mother work?” the director asked. “My mother cleaned clothes.” the young man said. The directorlooked the young man’s hands. He had a pair of smooth and perfect hands.“Have you ever helped your mother wash the clothes before?” the director asked. “Never,” the young man answered. “I have a requ est,” the director said. “When you go back home today, go and clean your mother’s hands, and then see me tomorrow morning.”The young man felt that his chance of getting the job was high. When he went back, he happily asked his mother to let him clean her hands. His mother felt strange; happy but with mixed feelings. She showed her hands to the kid. The young man cleaned his mother’s hands slowly. His tears fell as he did that. It was the first time he had noticed his mother’s hands were so wrinkled. He realized it was this pair of hands that helped him pay the fees.The next morning, the young man went to the director’s office.“I cleaned my mother’s hands, and I know that without my mother, I would not be the person I am today.” he said.“This is what I am looking for in my manager.” the director said. “I want a person who can appreciate (感激) ” the help of others to get things done.
