Here are some cool ones that are already in stores or will be there soon.Portable ToasterThere is actually an idea of a knife that could not only cut the bread into small pieces, but be healed enough to toast a slice of bread. You could take this time-saving and easy-to-clean tool anywhere. It would be really cool, for it looked like a light saber (剑).Hand-Held Copy & Paste ToolCopy & Paste allows you to scan and print images anywhere and on anything. Simply push she button and scan the object, and then the image can be printed on any surface using ink. For the moment, this is only an idea, but when this device is on sale, there will be a long line waiting to buy it.Electronic Sensor PenWith Phree Pen, you can write anything anywhere. When it went into market, it became really popular. All the symbols can be written on any surface, read by a computer and sent to a smart phone or a computer. You can write things down without paper at hand.Scanner Determining Food Composition (成分)TellSpec was made for those who want to quickly know the composition of a dish. It scans the products and then sends a list of information about the nutritional value to a special phone app. Now you don’t need to worry about the safety of the products you eat.41.

According to the passage, how many inventions are only ideas now?A. One. B. Two. C. Three. D. Four.BGrandpa and MeAs my summer vacation drew nearer and nearer, I made a long list of things I wished to do and could hardly wait to begin a brand-new journey. However, when my mom told me that I had to live with my grandfather for six weeks, I complained. A voice inside me said that it would be miserable to live with my grandpa, which meant no afternoon baseball games with my neighborhood friends.The first week with Grandpa was fine. We went out for dinner and watched TV together. One day, Grandpa was sitting at the table reading the newspaper. I sat on the couch and flipped (快速翻动) through my baseball card collection. “Wish I had a Hank Aaron card,” I said to myself.When Grandpa heard me, he said in surprise, “I didn’t know you liked baseball, Susan.” I explained that it was my favorite sport and I usually played it all summer with my friends. Grandpa stood up shakily and walked to the door. “Let’s go,” he said, with excitement. “I want to show you something.”We drove for quite a while, and when Grandpa finally stopped the car, we were in front of some old houses. A sign on each house said “Land Will Be Sold. Call For Details.” I noticed that Grandpa had a faraway look in his eyes. “I haven’t been here for decades,” he whispered. “Probably twenty or thirty years.” We walked there and he pointed down the street and said, “That’s the field where I used to play baseball every summer.” Then I realized where we were: This was the house where Grandpa grew up! We looked inside a window and saw a big mess. No one had lived here for a long time.On the ride home, Grandpa was very quiet. I thought about how he must miss his old home and the friends he grew up with. If he could just go back in time for a few minutes, he would feel very happy and less lonely. Then I realized that six weeks away from home was not too bad, especially with Grandpa around.44.

The development of self-control begins at birth and continues throughout our lives. As babies, we have little or no control over our behaviors and emotions, but as we get older, with the help of parents or caregivers, we learn how to take turns, how to pay attention in class, stick to a challenging task, and restrain (制止) from hitting another child. These abilities continue to develop in our childhood and then youthbood. Also, it is clear that being impulsive (易冲动的) can have bad effects on children, causing interpersonal problems, poor physical health, and psychiatric disorders.Therefore, by learning self-control, children can make right decisions and respond to situations in positive ways. One of the effective strategies, when helping children develop self-control abilities, is to select developmentally proper tasks. Try setting up simple goals first, where success is expected, before moving onto the next goal. For preschoolers, goals might include not interrupting or not fighting on the playground. For early elementary school students, right goals might be following bedtime rules.However, it’s not enough to set up simple goals, because for children of the same age, there are still some differences in the development of self-control abilities. Some general strategies often help them learn right self-control behaviors.● Take a breakEncourage children to take a break or “time in” whenever they feel down, annoyed or angry. Stepping away from an upsetting situation can help a child calm down.● Teach and provide attentionPaying attention is a skill that can be taught. Encourage children to resist interrupting by learning to observe others without talking, so they can join in easily. Make sure to provide children with attention at times so they don’t feel ignored and therefore are unlikely to interrupt.● Use proper rewards (奖励)In order to develop positive behaviors, children need frequently positive feedback. Praise and consistent feedback can be highly rewarding for young children. It is important to let a child know what a desired behavior is.● Use activities designed to teach self-regulation (自我管理)Using specific activities can help teach young children skills that improve self-control. Some of these skills include dealing with “wanting something I can’t have”, understanding feelings, and controlling anger.47. What can we learn from Paragraph 1?A. As people get older, their attention will improve naturally.B. Being impulsive can often cause bad results in children’s grades.C. Children can learn how to control themselves with the help of parents.D. Self-control development begins at birth and keeps growing till youthbood.48. What can teachers do when students feel very disappointed?A. Teach and provide attention. B. Give rewards and suggestions.C. Teach skills to regulate themselves. D. Encourage them to take a break.49. Which of the following would be the best title for the passage?A. Time Waits for No Man—The Development of Self-ControlB. Have Power over Your Mind—Tips on Developing Self-ControlC. Prevention Is Better than Cure—Rules of Self-Control BehaviorsD. Think Twice Before You Act—The Importance of Self-Control SkillsDTechnology ProgressOn June 22, 1927, Charles Lindbergh flew into Dayton, Ohio, for dinner at Orville Wright’s house. It had been just a month since the young pilot’s first ever individual nonstop crossing of the Atlantic, and he felt he ought to pay respects to the pioneer of flight.Forty-two years later, on July 16, 1969, Apollo 11 astronaut Neil Armstrong was allowed to bring a personal guest to the Kennedy Space Center to view the launch of NASA’s towering Saturn V rocket. Armstrong invited his hero, Charles Lindbergh. That’s how fast technology advanced in the 20th century.However, progress isn’t what it used to be now. Northwestern University economist Robert Gordon argues that by 1970, all the key technologies of modern life were in place: electricity, highways, telecommunications, and the like. After that, innovation (创新) and economic growth simply couldn’t keep going fast as the last 100 years—a period Gordon calls “the special century”. Gordon argues the lives of people in developed nations look and feel the same in 2020 as they did in 1979 or 1989.Sloping down is good in one small way, though bad in most of the ways that count. Rapid changes can sometimes be disorienting (令人迷惑的). And when things develop at a lower speed, people and institutions do have more time to breathe and fit in. But slowing down isn’t what it should be. In many areas of technology, the forward movement today feels tragically slow, even nonexistent.Consider consumer robotics. There’s huge potential for robots to help us. But home robotics companies seem to keep folding. For example, social robot maker Jibo closed in Mareh after raising almost 73 million.Our century’s one signature technology achievement is smartphones. At this point, we’ve had them in our pockets long enough to begin to appreciate their dangers. Meanwhile the list of possibly world-changing technologies that get people’s attention but still remain in the original stage is very long. Self-driving cars, AR glasses. Need I continue?Indeed, these are all hard problems. But historically, solving the big problems has required continuous, large-scale investment (投资), often with private markets and taxpayers sharing the cost. In this century, we need to undo some bad results of the last great boom (繁荣) by developing affordable zero—and negative—emissions technologies right now. That’s another hard problem—and to solve it, we’ll need to rethink what made the “special century” so special.50. The writer mentions Charles Lindbergh in Paragraphs 1 and 2 to show that ________.A. Charles had contributed greatly to technologyB. Charles paid respects to the pioneer of flightC. technology developed rapidly in the 20th centuryD. technology has advanced to a higher new level51.

Some world-changing technologies are not making progress.B. Home robotics companies failed because of little investment.C. It’s time to realize the disadvantages of fast development now.D. It doesn’t take us long before we realize the dangers of smartphones.53. The writer probably agrees ________.A. markets and taxpayers have a duty to develop technologiesB. innovation and investment are needed for technology advanceC. what made the last century special will happen in the new centuryD. rapid changes in technology are bad in most of the ways that count
