Read the article and select the best answer. Article: For most caffeine consumers, its chief benefit is that it helps you get more done. This is what makes it unusual, says Stephen Braun, author of Buzz: The Science and Lore of Alcohol and Caffeine. "Its appeal is that it helps us earn more money," he adds. "What makes it different from other drugs is that it's used as a productivity tool -- not for pleasure." Many of history's creative minds have also been associated with a large amount of caffeine consumption. According to one biographer, the French novelist and playwright Balzac drank as many as 50 cups of coffee a day. "Were it not for coffee one could not write, which is to say one could not live," he once insisted. For seven years, the film-maker David Lynch ate at the same Los Angeles diner every day, drinking up to seven sweetened cups of coffee "with lots of sugar" in one sitting, which he said would guarantee that "lots of ideas" arrived. Ludwig van Beethoven was said to have painstakingly counted out exactly 60 coffee beans per cup when he brewed coffee. Perhaps recent tales of caffeine excess featured the singer Robbie Williams, who reportedly consumed 36 cups of black coffee and 20 cans of Red Bull a day. It is the routine task itself, as much as the stimulating effects of caffeine, that makes the process so important, says Mason Currey, author of Daily Rituals: How Artists Work. "A lot of artists use the process of making coffee as a gateway to the creative process," he adds. "You need to get into the right mindset to do that sort of work, and the preparation process provides a focus." One problem with attempting to control caffeine, says Braun, is that it affects everyone differently -- it is impossible to work out a "safe" limit that works for everyone. "Eventually, you have to become your own scientist -- there isn't an alternative to careful self-experimentation," he says. Question: What does Braun advise us to do in the end? Options: A: To drink less coffee. B: Never to take more coffee than you need. C: Never to limit caffeine use. D: To work out a safe level of caffeine use.

Article: If you have ever been left wondering why your emails are riddled with grammatical errors, or why you can never quite find the right phrase, it may be because you are typing with both hands. Our vocabulary becomes richer and our writing style becomes more fluent when we type using just one hand, scientists have found. "Typing can be too fluent or too fast, and _ can actually weaken the writing process," said Srdan Medimorec, the lead author of the study conducted at the department of psychology at the University of Waterloo, Canada. "It seems that what we write is a product of the interaction between our thoughts and the tools we use to express them." Using text-analysis software, researchers asked 103 university students to write essays under different conditions, using one hand to type and using both hands to type. The software was used to analyze elements of the essays, such as range of vocabulary, sentence complexity and the cohesion of the writing. Researchers found that participants' vocabulary became more advanced when they typed with one hand rather than two. The research team said that by slowing our writing down, typing one-handed allows more time for an internal word search, resulting in a larger variety of words. In contrast, fast typists might just write the first word that comes to mind. However, it is important not to slow typing down too much. Those who typed essays one-handed in the current study slowed down to about the speed of handwriting. This is the first study to show that changing people's typing can make their writing get better. The researchers suggested that the speed of writing could affect writing quality regardless of the tools used, whether they are computers, or pen and paper, although further research would be required to prove that idea. Question: Which is the best title of the passage? Options: A: How to become a good writer? B: Typing with both hands could make you a worse writer. C: Slower typing, fewer mistakes. D: Elements weakening the writing process

Q: Read the article and select the best answer. Article: The United States is not part of the Kyoto Protocol.But since 2005 more than 1,000 mayors across the country have agreed to sign their own version of the protocol. It is called the United States Conference of Mayors' Climate Protection Agreement.Local leaders have agreed to follow the suggestions of the Kyoto Protocol in their communities.They have also agreed to urge state and federal governments to follow these suggestions.One goal is to reduce air pollution to the 1990 levels by 2012. A "green" city might work on several kinds of environmental goals and programs.These include air quality,reducing electricity use, green building, public health, the reuse of materials, water quality and clean transportation. The Natural Resources Defense Council works to protect the environment through action, law and science.One of its online projects is called Smarter Cities, which lists some cities that have made important environmental steps. Washington,D.C.is also a leading city for green roofs,with over 92,000 square meters of green rooftops.The city also launched a program called "Skip the Bag,Save the River."Stores charge people a fivecent tax for using plastic or paper shopping bags instead of reusable bags.Money from the tax will be used to clean up a local river. New York City is using water as a renewable energy source.For several years, the city has experimented with water in the East River to create energy.Officials operating the program recently asked for permission to put into place 30 river turbine devices. The people of Portland, Oregon are among the top recyclers in the nation.People living there recycle over half of the waste they throw out.The city has also worked to provide green transportation by providing safe bike paths and free parking spaces where electric cars can get recharged. In Oakland, California, you can ride on one of several public hydrogenpowered buses.These buses release zero pollution into the air.However,they cost about five times more than common buses. Question: One obvious disadvantage of adopting hydrogenpowered buses is _ . Options: A: its high cost B: side effect C: zero pollution D: large space
A: A
