填空题Ready to Scream? Fear can be fun. Many young people queue up to ride very fast and scary (吓人的) roller coasters, screaming but enjoying themselves. Other people like to read "goose bumps" (鸡皮疙瘩) books or watch horror movies (恐怖电影) at night, scared to death but feeling excited. 1 Fear is an ancient way of surviving. Being scared makes animals (including humans) flee (逃走) from danger and save themselves. It is because of fear that we have lived through millions of years of evolution. 2 What happens in the brain when something frightens you? Nerves (神经) that begin at the eyes and ears lead to a part of the brain called the amygdala (扁桃体). When you suddenly see a snake, for example, the amygdala makes you freeze, perspire (流汗), have a quickened heartbeat, or run very fast. However, seeing the snake also uses another part of the brain, the cortex (皮层). It analyzes the situation, and if it finds that the snake is only made of rubber it tells your heart and the rest of your body to calm down. 3 Back to the first question: Why do some people like to make themselves scared? 4 Kalin said: "To believe we have control over a situation gives us a feeling of power." Scary movies or novels are good practice to prepare young people for the real thing. 5 And there might be some evolutionary advantage to being able to adjust this system that is there to protect people. A. Thrills (恐惧) such as roller coaster rides also go to the brain"s pleasure centre. B. Why do people like being scared? C. One reason is that we can play games with fear, and find ways to reduce the scariness by looking away or thinking of something else. D. Those who lacked a strong fear response (反应) were more likely to be killed, leaving the more timid and careful to pass their genes (基因) onto the next generation. E. Think of the amygdala as the engine and the cortex as the brake. F. Screaming saves ancient people"s life.

填空题Volunteers have to get prepared for the time in the calorimeter ______.

填空题The Weight Experiment Nicola Walters has been taking part in experiments in Scotland to discover why humans gain and lose weight. Being locked in a small room called a "calorimeter" (热量测量试) is one way to find out. 1. The signs above the two rooms read simply "Chamber One" and "Chamber Two". These are the calorimeters: 4m by 2m white-walled rooms where human volunteers are locked up in the name of science. Outside these rooms another sign reads "Please do not enter—work in progress" and in front of the rooms advanced machinery registers every move the volunteers make. Each day, meals measured to the last gram are passed through a hole in the wall of the calorimeter to the resident volunteer. 2. Nicola Walters is one of twenty volunteers who, over the past eight months, have spent varying periods inside the calorimeter. Tall and slim, Nicola does not have a weight problem, but thought the strict diet might help with her training and fitness programme. As a self-employed community dance worker, she was able to fit the experiment in around her work. She saw an advert for Volunteers at her local gym and as she is interested in the whole area of diet and exercise, she thought she would help out. 3. The experiment on Nicola involved her spending one day on a fixed diet at home and the next in the room. This sequence was repeated four times over six weeks. She arrived at the calorimeter at 8:30 am on each of the four mornings and from then on everything she ate or drank was carefully measured. Her every move was noted too, her daily exercise routine, timed to the last second. At regular intervals, after eating, she filled in forms about how hungry she felt and samples were taken for analysis. 4. The scientists help volunteers impose a kind of order on the long days they face in the room. "The first time, I only took one video and a book, but it was OK because I watched TV the rest of the time," says Nieola. And twice a day she used the exercise bike. She pedaled (踩踏板) for half an hour, watched by researchers to make sure she didn"t go too fast. 5. It seems that some foods encourage you to eat more, while others satisfy you quickly. Volunteers are already showing that high-fat diets are less likely to make you feel full. Believing that they may now know what encourages people to overeat, the researchers are about to start testing a high-protein weight-loss diet. Volunteers are required and Nicola has signed up for further sessions.

填空题Geology and Health 1. The importance of particular metals in the human diet has been realized within the past few decades, and the idea that geology might be related to health has been recognized for a number of elements such as iodine, zinc and selenium. For example, soils with low iodine contents produce crops, and animals deficient in iodine. A lack of iodine in the human diet leads to some serious diseases. 2. The ultimate source of metals within the human body is rocks, which weather into soil, gaining or losing some of their chemical constituents. The crops we eat selectively remove from the soil the elements that they require for growth. The water we drink contains trace elements leached from rock and soil. Thus the geology and geochemistry of the environments have effects on the chemistry and health of plants, animals and people. 3. So far there is no data to suggest that people living on metal-rich soils experience a potential health hazard. The levels of metals within naturally contaminated soils are generally not high enough to cause serious health problems. Living on metal-rich soils does not represent a health risk unless large quantities of soil are digested or metal-rich dust is inhaled. However, small children are particularly exposed to metal-rich topsoil in playgrounds and gardens. They are also the most likely ones to eat potentially dangerous metal-rich soil. 4. Heavy metals are persistent: they do not break down to other chemicals in the environment. Industrially polluted sites usually undergo intensive clean-up and rehabilitation because heavy metals are a health concern once they enter the food chain. Some trace metals are alleged to cause cancer and are also known to cause poisoning. 5. In contrast, naturally contaminated soils have not been subject to risk assessment studies and re- habilitation measures, despite the fact that they frequently possess metal concentrations well above those of such polluted by humans and above environmental quality criteria. 6. There is a vital need to understand the potential risks and long-term health effects of living on naturally contaminated soils. Future environmental investigations of naturally polluted soils should concentrate on the potential pathways of metals into the food chain and human body. Geologists should be part of such studies as they can provide the essential background information on rock and soil chemistry as well as the chemical forms of heavy metal pollution.

By scanning the magnetic field generated as electric currents flow through objects, physicists have managed {{U}}(46) {{/U}}. The technology will allow manufacturers to scan microchips for faults, as well as revealing microscopic defects in anything from aircraft to banknotes. Gang Xiao and Ben Schrag at Brown University in Providence, Rhode Island, visualize the current by measuring subtle changes in the magnetic field of an object and {{U}}(47) {{/U}} Their sensor is adapted from an existing piece of technology that is used to measure large magnetic fields in computer hard drives. "We redesigned the magnetic sensor to make it capable of measuring very weak changes in magnetic fields," says Xiao. The resulting device is capable of detecting a current as weak as 10 microamperes, even when the wire is buried deep within a chip, and it shows up features as small as 40 nanometers across. At present, engineers looking for defects in a chip have to peel off the layers and examine the circuits visually; this is one of the obstacles {{U}}(48) {{/U}}. But the new magnetic microscope is sensitive enough to look inside chips and reveal faults such as short circuits, nicks in the wires or electro migration -- where a dense area of current picks up surrounding atoms and moves them along. "It is like watching a river flow," explains Xiao. As well as scanning tiny circuits, the microscope can be used to reveal the internal structure of any object capable of conducting electricity. For example, it could look directly at microscopic cracks in an aeroplane's fuselage, {{U}}(49) {{/U}}. The technique cannot yet pick up electrical activity in the human brain because the current there is too small, but Xiao doesn't rule it out in the future. "I can never say never," he says. Although the researchers have only just made the technical details of the microscope public, it is already on sale, from electronics company Micro Magnetics in Fall River, Massachusetts.

It's about a wacky(乖僻的) dad (who's also a scientist) who accidentally(偶然的) shrinks his kids with his homemade miniaturizing(使小型化) invention. Oops ! The kids spend the rest of the movie as tiny people who are barely visible while trying to get back to their normal size. {{U}} (46) {{/U}} It takes place over years and may add up to only one inch or so off of their adult height (maybe a little more, maybe less), and this kind of shrinking can't be magically reversed, although there are things that can be done to stop it or slow it down. But why does shrinking happen at all? {{U}} (47) {{/U}}. As people get older, they generally lose some muscle and fat from their bodies as part of the natural aging process. Gravity (the force that keeps your feet on the ground) take hold, and the bones in the spine, called vertebrae(椎骨), may break down or degenerate, and start to collapse into one another. {{U}}(48) {{/U}}. But perhaps the most common reason why some older people shrink is because of osteoporosis. Osteoporosis(骨质疏松症) occurs when too much spongy(海绵) bone tissue (which is found inside of most bones) is broken down and not enough new bone material is made. {{U}}(49) {{/U}}. Bones become smaller and weaker and can easily break if someone with osteoporosis is injured. Older people -- especially women, who generally have smaller and lighter bones to begin with -- are more likely to develop osteoporosis. As years go by, a person with osteoporosis shrinks a little bit. Did you know that every day you do a shrinking act? You aren't as tall at the end of the day as you are at the beginning. {{U}}(50) {{/U}}. Don't worry, though. Once you get a good night's rest, your body recovers, and the next morning, you're standing tall again. A. They end up pressing closer together, which makes a person lose a little height and become shorter. B. That's because as the day goes on, water in the disks of the spine gets compressed (squeezed) due to gravity, making you just a tiny bit shorter. C. Over time, bone is said to be lost because it's not being replaced. D. Luckily, there are things that people can do to prevent shrinking. E. For older people, shrinking isn't that dramatic or sudden at all. F. There are a few reasons.

填空题New Changes in American Life Once it was possible to define male and female roles easily by the division of labor. Men worked outside the home and earned the income to support their families, while women cooked the meals and took care of the home and the children. 1 But by the middle of this century, men"s and women"s roles were becoming less firmly fixed. In the 1950s, economic and social success was the goal of the typical American. But in the 1960s a new force developed called the counterculture. 2 The counterculture presented men and women with new role choices. Taking more interest in childcare, men began to share child-raising tasks with their wives. In fact, some young men and women moved to communal homes or farms where the economic and childcare responsibilities were shared equally by both sexes. 3 Some young men refused to be drafted as soldiers to fight in the war in Vietnam. In terms of numbers, the counterculture was not a very large group of people. 4 Working men of all classes began to change their economic and social patterns. Industrial workers and business executives alike cut down on "overtime" work so that they could spend more leisure time with their families. Some doctors, lawyers, and teachers turned away from high paying situations to practice their professions in poorer neighborhoods. In the 1970s, the feminist movement, or women"s liberation, produced additional economic and social changes. Women of all ages and at all levels of society were entering the work force in greater numbers. 5 But some women began to enter traditionally male occupations: police work, banking, dentistry, and construction work. Women were asking for equal work, and equal opportunities for promotion. Today the experts generally agree that important changes are taking place in the roles of men and women. Naturally, there are difficulties in adjusting to these transformations. A. In addition, many Americans did not value the traditional male role of soldier. B. Most of them still took traditional women"s jobs as public school teaching, nursing, and secretarial work. C. These roles were firmly fixed for most people, and there was not much opportunity for women to exchange their roles. D. But its influence spread to many parts of American society. E. The people involved in this movement did not value the middle-class American goals. F. A great many jobs that used to belong to men are now taken by women.

Long before he started a car company, he was a worker, known for picking up pieces of metal and wire and turning them into machines. He started putting cars together in 1891. Although it was by no means the first popular automobile, the Model T showed the world just how creative Ford was at combining technology and market.2 The company's assembly line alone threw America's Industrial Revolution into overdrive (高速运转). Instead of having workers put together the entire car, Ford's friends, who were great toolmakers from Scotland, organized teams that added parts to each Model T as it moved down a line. By the time Ford's Highland Park plant was humming (嗡嗡作响) along in 1914, the world's first automatic conveyor belt could turn out a car every 93 minutes.3 The same year Henry Ford shocked the world with the $5-a-day minimum wage scheme, the greatest contribution he had ever made. The average wage in the auto industry then was $2.34 for a 9-hour shift. Ford not only doubled that, he also took an hour off the workday. In those years it was unthinkable that a man could be paid that much for doing something that didn't involve an awful lot of training or education. The Wall Street Journal called the plan "an economic crime", and critics everywhere laughed at Ford.4 But as the wage increased later to daily $10, it proved a critical component of Ford's dream to make the automobile accessible (可及的) to all. The critics were too stupid to understand that because Ford had lowered his costs per car, the higher wages didn't matter--except for making it possible for more people to buy cars.
