I'm taking a test and have to guess the right answer to the question after the article. Article: No more batteries,no more chargers and no more wires.This is the future promised by "wireless power".a means of broadcasting electricity through the air to laptops,iPods and other gadgets without the need for cables and sockets . Wireless lighting,audio speakers and digital picture frames are expected to be among the first commercial products exhibited in Las Vegas this week at the International Consumer Electronics Show,the world's biggest gadgets tradeshow. Experts believe this is just the beginning and that eventually wireless electricity could do for battery life what WiFi did for,the Internet.In a world without wires,laptop users in cafes and airport terminals would be inside an "electricity hotspot" and no longer have to delve an awkwardly located socket.

Among the companies showcasing the ambitions technology at CES is Power Beam.Its system turns electricity into an invisible laser, then beams it as heat,across the room to a solar cell that conveys it back into dectricity. David Graham,the co-founder of Power Beam,said:"We're going to delete the word 'recharge' from the English dictionary.If your,cell phone is recharging on your desk.all day,you won't be thinking about.it." The Silicon Valley company can currently use a laser to generate about 1.5 watts of power to _ a solar.cell 10 meters away.This, sould be enough to power an electronic speaker or small LED lights,but not enough to operate a laptop,which requires about 30 to 50 watts.However,Graham said that the technology could comfortably be scaled up . Power Beam insists its laser does not lead to a risk to users' health because it is simply moving heat from one place... Question: Which of the following statements is TRUE? Options: A: The laser does harm to people's health. B: The gadgets like audio speakers have been shown at the International Consumer Electronics Show this week. C: The word 'recharge' has been deleted from the English dictionary. D: The technology Can also save energy because it would not work when unnecessary.

I'm taking a test and have to guess the right answer to the question after the article. Article: A young boy was sitting in the back seat of the car eating an apple. He asked his father, "Why does my apple turn brown?" his father answered, "When the skin is removed, air reaches the flesh of the apple and causes oxidation. This changes the apple's molecular structure and results in a brownish color." The boy asked, " Daddy, what are you talking about?" I know how that boy feels. Sometimes I want answers to some of those confusing questions that we all meet with, such as how to get through difficult times or what to do in a tough situation. I just want to get it right. The problem is that I don't always have the answer I need. Nobody else seems to have them, either. So I go on making mistakes and think that I'll never get it right. Often I didn't know what to do. I often made poor choices, but I gradually improved. Then I realized that I don't HAVE TO always get it right. I don't have to always know what to do all the time. All I really need to do is try my best, learn from my mistakes and go on. Dr. Leo Buscaglia once said, " No one gets out of this world alive, so the time to live, learn, care, share, celebrate and love is now. That would be pretty hard to do when you're waiting for all the answers first." So you got it wrong. You made a mistake. So what should you do next? Forgive yourself and try again. You may not get out of this world alive, but you can get plenty of life out of this world if you are not too worried about always getting it right. Question: What do Dr. Leo Buscaglia's words mean? Options: A: We must make right choices as often as possible. B: We can search the answers when enjoying life itself. C: People have many desires when they enter the world. D: It is hard to lead a happy and satisfying life.

I'm taking a test and have to guess the right answer to the question after the article. Article: One afternoon, in Paris, I took a trip to an art museum while waiting for my husband to finish a business meeting. I was looking forward to a quiet view of some great paintings of excellent artists. A young couple looking at the paintings in front of me were talking non-stop. I watched them a moment and decided she was doing all the talking. In fact, I was surprised at this man for putting up with her everlasting speech. Bored by their noise, I moved on. I met them several times as I moved through those rooms of art. Each time I heard her voice, I moved away at once. I was standing at the museum gift shop buying some cards when the couple walked to the exit . "He's a brave man," said the shop assistant. "Most of us would give up if we were blinded at such a young age. But he and his wife come in whenever there's a new art show." It explained the non-stop talk! A sudden sense of shame came to my heart for what I was thinking just now. "But what does he get out of the art?" I asked. "His wife describes each painting so he can see it in his head." At that moment I realized what is patience, courage and love. I saw the patience of a young wife describing paintings to a person who can't see and courage of a husband who would not allow blindness change his love towards art. And I felt the love shared by the two as I watched them walking away holding each other's hands. Question: The passage mainly shows us _ . Options: A: patience, courage and love B: how to watch paintings C: how art changed people's life D: a trip
