【文章內(nèi)容簡介】 I think in the future. My memories bee part of me. Moreover, as Van Boven has observed, young people who pursue happiness through “things” are liked less by their peers. People prefer those who pursue happiness through experiences. It’s natural to want to express yourself through your appearance. So my advice is: create a look that isn’t tied to a designer label. Convey your own message. Take some lessons from the late Apple cofounder Steve Jobs. He was always in Levis jeans and a black turtleneck. Mark Zuckerberg, founder of Facebook, routinely appears in hoodies and sneakers. These people, successful people, have style. You don’t have to break the bank to send a message about who you are. Take a trip. Go out into the world. Then e back and confidently create your own signature look. 28. What is the author’s opinion on spending a lot of money on luxury brands? A. Approving. B. Doubtful. C. Critical. D. Unconcerned. 29. Leaf Van Boven’s studies showed that . A. when people get luxuries they don’t suddenly bee happy B. experiences are more likely to bring people pleasure C. traveling changes a person’s personality greatly D. luxuries have a negative influence on people’s happiness 30. What is the author’s advice on expressing oneself? A. Be particular about designer labels. B. Try styles like Mark Zuckerberg’s. C. Choose styles that are simple and fortable. D. Create your own personal and unique style. 31. What does the underlined phrase “break the bank” most probably mean? A. Use up all the money. B. Break into the bank. C. Borrow from the bank. D. Draw from a bank account. D When a laptop or smartphone battery starts losing its power, the only choices are to buy an expensive replacement, or just keep it plugged in all the time. But one woman may have found the solution to this problem. Mya Le Thai is a scientist studying at the University of California. She recently discovered a process that might lead to batteries that last forever. Thai said she had been frustrated that the batteries for her wireless devices kept losing power over time, until they failed to charge fully. Thai did not like having to keep her laptop connected to an electric outlet (插座 ) to keep it powered on. So, she decided to do something about that problem. At first, she and her team at UC thought about inventing a new battery. But as they experimented, Thai discovered something that might permit lithiumion (鋰離子 ) batteries to last forever. Lithiumion batteries power most wireless devices. Over time, the batteries lose the ability to hold a charge (電荷 ). Most of these batteries have a life of about 7,000 charging cycles before they die. One of the reasons why lithiumion batteries are losing power is their use of nanowires (納米線 ) to carry electricity. Nanowires are extremely thin. A human hair is thousands of times thicker, for example. Nanowires are extremely efficient carriers of electricity, which makes them useful in batteries. But Thai said their thinness also makes them weak. “Nanowires break over time,” she said. “That’s why they fail.” But, Thai had a theory— the nanowires might last longer if covered with a gel (凝膠 ). She and her team tested this theory. “It was a long proce ss and a lot of work,” Thai said. The team tried many coverings for the wires. PMMA, a type of plastic, was one of them. The nanowires were covered with PMMA and charged 200, 000 times. The PMiMA covered nanowires showed no evidence of damage. The results suggested that batteries could last forever, without losing charging ability. Thai hoped to continue her research to understand why this gel worked so well and to see if any other gel could create better results. Mya Le Thai said she was glad that her discovery had got such attention. “It’s kind of cool,” she said. “I’m really glad people are showing interest in my work, also in technology and energy.” 32. What caused Thai to work on lithiumion batteries? A. She was frustrated that her batteries lost power gradually. B. She disliked the batteries for her laptop. C. She thought batteries were too expensive. D. She and her team were assigned to invent a new battery. 33. Which of the following sentences is TRUE about nanowires? A. They are too weak to carry electricity. B. They last only 7,000 charging cycles. C. Their failure is the main cause of battery dying. D. They are not suitable to use in batteries. 34. The breakthrough of the research lies in . A.
