A study has showed that the brain makes decisions about 10 seconds before a person realizes it.Experts involved in the study said that looking at brain activity while making a decision, they could predict the choices the subjects would make, before they realized that they had made a decision. Lead researcher John-Dylan Haynes, a neuroscientist (神经学家)at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, said that the new findings called into questions for “consciousness”of decisions that people make, and might even challenge ideas as to how“free”people are to make a decision at a particular moment.“We think our decisions are conscious, but these data show that consciousness is just the tip of the iceberg,”Nature magazine quoted (引用) him as saying. Thinking the results“quite dramatic”, Frank Tong of Vanderbilt University in Nashville, Tennessee, said that 10 seconds is“a lifetime”in terms of brain activity.During the study, the brains of 14 volunteers were imaged as they performed a decision-making task. The subjects had two buttons before them, each to be operated by a different hand, which they could press when they felt the urge to. They were simultaneously (同时地)shown a stream of letters, which appeared on a screen at half-second intervals (间隔). The volunteers had to remember which letter was showing when they decided to press their button.Upon analysis of the data, the researchers realized that the earliest signal they could catch started seven seconds before the volunteers reported having made their decision. Given the delay of a few seconds in the imaging, they reckoned (估计) that the brain activity could have begun about ten seconds before the conscious decision. The researchers showed that the signals were picked up from a region (区域)called the frontopolar cortex (脑额极皮层), which is located at the front of the brain, immediately behind the forehead.While writing about the observations made during the research in his study report, Haynes said that the frontopolar cortex might be the brain region where decisions are started. He also showed that the next step in the research would be to speed up the data analysis so as to enable histeam to predict people’s choices as their brains would make them.1. The passage tells us that ______.A. we are aware of our whole process of decision-makingB. people don’t make decisions until they realize itC. experts have no way to tell what decision one will makeD. the decision-making process starts before it is made2. The underlined word “subjects”in Para. 2 probably refers to ______.A. the topic of the experts’ research paperB. the scientific subjects that the experts were studyingC. the things that experts don’t know clearlyD. the volunteers that the experts worked on for their research3. The underl ined sentence“consciousness is just the tip of the iceberg”in Para. 4 means that ______.A. our decision-making is consciousB. the data contains a lot of information besides consciousnessC. consciousness is the major part of the dataD. 10 seconds is“a lifetime”in terms of brain activity4. The final purpose of the research ______.A. is not stated clearly in the passageB. is not acknowledged by expertsC. is to show where decision-making startsD. is to analyze the data picked up5. The passage implies that ______.A. the research has been completedB. the research was conducted by two expertsC. the decision-making process lasts only about 10 secondsD. we may predict what decisions people will make in the future【参考答案】1—4、DDBA【2014模拟】阅读理解。

阅读下列四篇短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。

Do you know of anyone who uses the truth to deceive(欺骗)?When someone tells you something that is true，but leaves out important information that should be included，he can give you a false picture．For example，someone might say, ''I just won a hundred．dollars on the lottery(彩票)．It was great．I took that dollar ticket back to the store and turned it in for one hundred dollars!"．This guy's a winner，right? Maybe，maybe not．We then discover that he bought$200 worth of tickets, and only one was a winner．He’s really a big loser! He didn't say anything that was false，but he left out important information on purpose．That's called a half-truth．Half truths are not technically lies，but they are just as dishonest．Some politicians often use this trick．Let’s say that during Governor Smith’s last term，her state lost one million jobs and gained three million jobs．Then she seeks another term．One of her opponents says, “During Governor Smith’s term，the state lost one million jobs!” That’s true．However，an honest statement would have been，“During Governor Smith’s term, the state had a net gain of two millio n jobs.”Advertisers will sometimes use half-truths．It's against the law to make false statements so they try to mislead you with the truth．An advertisement might say，''Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache．'' It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company．This kind of deception happens too often．It’s a sad fact of life：Lies are lies，and sometimes the truth can 1ie as well．【小题1】The underlined word“opponents”in Paragraph 3 means ．A．enemy B．partner C．cooperator D．assistant【小题2】We may infer that the author believes people should ．A：．buy lottery tickets if possible B．make use of half-truthsC．be careful about what they are told D．not trust the Yucky Company【小题3】How many examples does the writer give to show how the truth is used to deceive?A．One． B．Two． C．Three．D．Four．【小题4】Which of the following is true according to the passage?A．Using half truths is against the law．B．Technically，half truths are in fact lies．C．Yucky Pills is a very good medicine for toothache．D．Governor Smith did a good job during her last term．【小题5】M1ich of the following best expresses the main idea of the passage?A．He’s really a big loser!B．Sometimes the truth can lie as well．C．Advertisers will sometimes use half truths．D．It’s against the law to make false statements．【答案】【小题1】A【小题2】C【小题3】C【小题4】D社会生活类The world economy has run into a brick wall. Despite countless warnings in recent years about the need to address a potential hunger crisis in poor countries and an energy crisis worldwide, world leaders failed to think ahead. The result is a global food crisis. Wheat, corn and rice prices have more than doubled in the past two years. And oil prices have increased more than three times since the start of 2004. These food-price increases, combined with increasing energy costs, will slow if not stop economic growth in many parts of the world and will even affect political stability. Practical solutions to these problems do exist, but we’ll have to start thinking ahead and acting globally.Here are three steps to ease the current food crisis and avoid the potential for a global crisis. The first is to promote the dramatic success of Malawi, a country in southern Africa, which three years ago established a special fund to help its farmers get fertilizer and seeds with high productivity. Malawi’s harvest doubled after just one year. An int ernational fund based on the Malawi model would cost a mere $10 per person annually in the rich world, or $10 billion altogether.Second, the U. S. and Europe should abandon their policies of paying partly for the change of food into biofuels. The U. S. government gives farmers a taxpayer-financed payment of 51 cents per gallon of ethanol(乙醇) changed from corn. There may be a case for biofuels produced on lands that do not produce foods—tree crops, grasses and wood products—but there’s no case for the government to pay to put the world’s dinner into the gas tank.Third, we urgently need to weather-proof the world’s crops as soon and as effectively as possible. For a poor farmer, sometimes something as simple as a farm pond—which collects rainwater to be used in dry weather—can make the difference between a good harvest and a bad one. The world has already committed to establishing a Climate Adaptation Fund to help poor regions climate-proof vital economic activities such as food production and health care but has not yet acted upon the promise.1. An international fund based on the Malawi model would .A. cost each of the developed countries $10 billion per yearB. aim to double the harvest in southern African countries in a yearC. decrease the food prices as well as the energy pricesD. give poor farmers access to fertilizer and highly productive seeds2. With the second step, the author expresses the idea that .A. it is not wise to change food crops into gasB. it is misleading to put tree crops into the gas tankC. we should get alternative forms of fuel in any wayD. biofuels should be developed on a large scale3. Which of the following is true according to the passage?A. A rain-collecting pond is a simple safeguard against by weather.B. A Climate Adaptation Fund has been established to help poor regions.C. The world has made a serious promise to build farm ponds.D. It makes a great difference whether we develop wood products or not.4. In the passage, the author calls on us to .A. slow down but not to stop economic growthB. develop tree crops, grasses and wood productsC. achieve economic growth and political stabilityD. act now so as to relieve the global food shortage【参考答案】47.1-4 DAAD阅读理解-------AWalk through the Amazon rainforest today and you will find it is steamy, warm, damp and thick. But if you had been around 15,000 years ago, during the last ice age, would it have been the same? For more than 30 years, scientists have been arguing about how rainforests like the Amazon might have reacted（反应）to the cold, dry climates of the ice ages, but until now, no one has reached a satisfying answer.Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping toslow global warming. Currently the trees in the Amazon take in around 500 million tones of CO2 each year; equal to the total amount of CO2 giving off in the UK each year. But how will the Amazon react to future climate change? If it gets drier ,will it still survive and continue to draw down CO2 ? Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past. Unfortunately, getting into the Amazon rainforest and collecting information are very difficult. To study past climate, scientists need to look at fossilized pollen, kept in lake muds. Going back to the last ice age means drilling deep down into lake sediments （沉淀物）, which requires specialized equipment and heavy machinery . There are very few roads and paths, or places to land helicopters and aeroplanes. Rivers tend to be the easiest way to enter the forest ,but this still leaves vast areas between the rivers completely unsampled（未取样）. So far, only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon rainforest reacts to climate change.1. The underlin ed phrase “mopping up” in the second paragraph means ________.A. cleaning upB. taking inC. wiping outD. giving out答案解析：答案为B。
