Question: 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 _ .
Options: (A) batteries should be greatly improved (B) petrol will be used instead of batteries (C) the time of batteries will be gone forever (D) pollution problems caused by batteries must be solved
Asnwer: C

Answer: Yes

Question: Article: Many university students dislike studying history because there is little to get excited about when historical events are presented in a boring manner. However, I'll never forget my American History professor, Dr. Williamson. Each event leaped from the pages of our text and became as real as the daily news report on the radio. My favorite lecture concerned the American Revolution. Dr. Williamson set the mood for the study by imitating Pall Revere, a well-known silversmith, working in his shop. The American colonists were angry because of the British control over their lives. Revere felt that war between the British and the colonists was inevitable. Then, Dr Williamson told us about Revere rowing across the Charles River from Boston on April 18,1775. I could see the professor row as he raised his hand to his forehead as if he were looking across the Charles River to the old North Church in Boston. Suddenly, Revere spotted two lanterns, a signal which meant that the British would attack by sea. He jumped on his horse to warn the villagers of the attack. Professor Williamson reminded us that the first battles of the American Revolution were fought at Concord and Lexington, Massachusetts, the year before the Declaration of Independence was signed in 1776. Never before had history seemed so alive to me. And all because a professor cared enough to put his heart into his teaching.
Question: The writer will never forget his American History professor because he _ .
Options: (A) would record all historical events onto the radio (B) would get very excited when giving lessons (C) would always teach the students the American Revolution (D) would make his class lively and interesting
Asnwer: D

Answer: Yes

Question: Article: China, known as the "kingdom of bicycle", will see a quick growth in electric bicycle production in the next five years thanks to the country's efforts to save energy and improve the environment. The output of electric bikes is expected to maintain an annual growth rate of at least 80 percent in the coming five years. China will _ 30 million electricity-driven bikes in 2020, compared to 9 million bikes last year, according to a report from the Development Research Center under the State Council and other ministries such as the National Development and Reform Commission. The central government wants to reduce the amount of energy consumption by as much as 20 percent within the next five years. That would be achieved through the introduction of new sources of energy and encouraging people to save energy, China Daily reported. The smoke from car exhausts is a major cause of pollution darkening the sky in Chinese cities, especially Beijing. On Monday, industrial experts called on the government to come up with more preferential measures to spread the use of electric bikes in China. Electric bike production in China accounts for about 90 percent of the world's total, making China the world's biggest producer, consumer and exporter of the energy-efficient vehicle, the report said. The country last year sold about 3 million electric bikes to foreign countries, a figure expected to double in five years. By 2020, the production value of the electric bike industry in China is expected to be 70 billion yuan, almost four times of the current level.
Question: Why will there be a quick growth in electric bicycle production in the next five years in China?
Options: (A) Because electric bicycles can save the consumer more money. (B) Because the central government encourages people to save energy. (C) Because most people in China can't afford cars. (D) Because the Chinese government limits the development of bicycle production.
Asnwer: B

Answer:
Yes
