Read the following article and select the best answer. Article: A Battery's Nightmare Portable electronics that can be carried about easily are only as good as their batteries and, let's face it, batteries aren't very good, especially when compared with, say, petrol, which packs 100 times a battery's energy into an equal space. That's why a large group of mechanical engineers (centered at the Massachusetts Institute of Technology, but with partners at other universities and companies) are hard at work in an effort to replace batteries with a tiny engine that runs on fuel. Imagine a battery-free life! When the fuel runs out in your mobile phone, you just fill up and go. The engine---about the size of a ten-cent coin---starts with a combustion chamber that burns hydrogen. Its tiny parts are etched onto silicon wafers in the same manner that computer parts are etched onto integrated circuits . The first engine is made up of five wafers. And since these wafers could be produced in much the same way as computer chips, they could probably be produced quite cheaply. But the _ in all this nice detail is efficiency. Tiny engine parts don't always behave like the bigger parts of the first engine. Something between the parts can slow down the works, according to Columbia University Professor LucFrechette, one of the engine's designers. Extreme heat from the combustion chamber is also a problem, often leaking to other parts of the engine. The scientists' goal is to create an engine that will operate 10 times better than batteries operate. Frechette says that a complete system, with all parts in place and working, will be set up in the next couple of years, but commercial models aren't likely until at least the end of the next ten years. Question: According to the passage, the title suggests that _ . - batteries should be greatly improved - petrol will be used instead of batteries - the time of batteries will be gone forever - pollution problems caused by batteries must be solved
the time of batteries will be gone forever

Read the following article and select the best answer. Article: Are you reading this while sitting in an office cubicle ? If so, please take a moment and glance around you. Are there photos of your last vacation hung on the wall? One of your kid's drawings? A yellowed print of a favorite cartoon? If so, you are doing something good for both yourself and your organization. Newly published research suggests working in an environment that offers little privacy can lead to emotional exhaustion and burnout . But personalizing one's workplace is an effective protection against such unwanted outcomes. "Individuals may take comfort from the items with which they surround themselves at work, and these items may help employees to keep emotional energy high in the face of stresses that come from their work," writes a research team led by Gregory Laurence of the University of Michigan-Flint, Michigan, in north central U.S. In the Journal of Environmental Psychology, Laurence and his colleagues describe a study featuring 87 white-collar employees at a large, urban university in the Midwestern United States. Research assistants noted whether they worked in a private office (with a door that can be closed) or a cubicle. They also counted the number of items each worker had brought from home to decorate his or her workspace - a list that included photographs, posters, artworks. Not surprisingly, Laurence and his colleagues found a connection between the amount of privacy an employee enjoys and his or her rate of burnout. "High privacy conditions tend to serve as strong protectors against unwelcome interferences and distractions ," they noted, "contributing to a work environment supporting reduced emotional exhaustion." But this link disappeared when those employees had personalized their cubicles. Employees who had turned their workspaces into areas that reflect their interests and personalities reported the same (relatively low) level of emotional exhaustion, no matter whether they worked in an office or a cubicle. The research confirms "the calming effect" of having your own stuff... Question: Who might be most interested in the passage? - Job hunters. - Office workers. - Kid's parents - Employment researchers.

Read the following article and select the best answer. Article: In a cab, a woman seemed in such a hurry. She constantly rushed the cab driver to drive quickly. She was so absorbed in her own thoughts of getting to the airport as soon as possible that she was not aware they were going by a different route. All of a sudden, a young man got inside the cab. He took her handbag in which she had put her visa, passport, and all the money for the trip. The cab driver, who was _ the robber, left her in the exactly middle of a dark street. She thought that she was rather unfortunate in the very situation. During the very night, she was told a piece of shocking news. Tears came down her cheek. Flight 360, the plane that she should have got on board, had crashed. Had she not lost her important belongings, she could surely have lost the thing far more precious----her life. Sometimes bad things really happen. There are times when nothing seems to go our way. So what should we do about it? We must get rid of all these frustrations and start all over again in the faith that we will get what we deserve. Don't waste your time and energy on things that can't be changed. Continuous worrying will only affect your health and you'll be doing much more damage than what was previously done. What if it was the other way round? What if we never ran out of good luck? There was a man who won the lottery. He became greedy and wasted all his money on everything he could get his hands on. But when he one day made it to the front page of the newspaper again, it was a different story. He had been killed because of his riches. If you attain good luck, you can never be too secure about it. Life is so unpredictable. You never know what will happen next. Live one day at a time. We sometimes subject ourselves to unnecessary emotional trouble. But please don't forget: sometimes misfortune can be the source of happiness. Live for the moment. Do what must be done for the present and the future will turn out just fine. Believe me. And believe in yourself. As Captain Planet always says, "The power is yours!" Question: From the passage, we learn that _ . - robbers are sure to get what they want - somebody never runs out of good luck - the woman was lucky to miss her flight - if one feels oneself lucky, he or she will continue to be so
the woman was lucky to miss her flight
