A research has shown that nearly 90 percent of traffic accidents are caused by human errors. So our aim is a fully autonomous (自动的) car that gets rid of the cause of most accidents: the driver. Researcher Hodgson points out, “For safety, the faster you can remove humans, the better, even if there are unfortunately a few accidents from new causes. It’s a question of balancing the number injured or killed by autonomous vehicles with the people whose lives are potentially saved.”
It’s an idea that Elon Musk, chief executive of electric car company Tesla Motors, has long believed. His company is determined to be the first to deliver a fully autonomous vehicle to consumers. Last year, Musk announced that Tesla’s 2019 goal was “to do an example drive of full autonomy all the way from L. A. to New York， and have the car park itself.
However, even Tesla admits that there are problems to overcome—the software needs further validation (批准生效) and the appropriate regulatory approval needs to be in place. Indeed, recent crashes of Tesla vehicles and Google cars confirm that the software isn’t ready yet.
The UK government appears committed encouraging the development of autonomous vehicles. It’s supporting four city trials, publishing the Modern Transport Bill to reduce red tape around their introduction and adapting the legal system to take into account problems such as insurance liability when a human isn’t in control of a vehicle.
The insurance industry is similarly eager to help increase autonomy in cars. As the Association of British Insurers points out, “Nearly 90 percent of road accidents are caused by human errors.” This costs motor insurers a shocking $20 million per day in claims.
1.What difficulty does the company Tesla Motors have?
A. The company lacks confidence to make new creations.
B. New inventions may cause more injuries and deaths.
C. The software should be made officially acceptable.
D. The traffic regulation has proved unreasonable.
2.What is the UK government’s attitude to autonomous cars?
A. Cautious. B. Positive.
C. Ambiguous. D. Disapproving.
3.What is the main idea of the last paragraph?
A. Insurance companies would like to support autonomous cars.
B. Human mistakes may be the key cause of traffic accidents.
C. Traffic accidents waste insurance companies quite a lot.
D. Motorists are surprised to hear about autonomous cars.
4.The purpose of writing the text is to ________.
A. amuse readers with funny examples
B. show his deep love for autonomous cars
C. introduce a new development in technology
D. provide a persuasive argument against autonomy

Research has shown that two-thirds of human conversation is taken up not with discussion of the cultural or political problems of the day, not heated debates about films we've just watched or books we've just finished reading, but plain and simple ____.
Language is our greatest treasure as a species, and what do we ____ do with it? We gossip. About others' behaviour and private lives, such as who's doing what with whom, who's in and who's out-and why; how to deal with difficult ____ situations involving children, lovers, and colleagues.
So why are we keen on gossiping? Are we just natural ____, of both time and words? Or do we talk a lot about nothing in particular simply to avoid facing up to the really important issues of life? It's not the case according to Professor Robin Dunbar. In fact, in his latest book, Grooming, Gossip and the Evolution of Language, the psychologist says gossip is one of these really____issues.
Dunbar ____ the traditional view that language was developed by the men at the early stage of social development in order to organize their manly hunting activities more effectively, or even to promote the exchange of poetic stories about their origins and the supernatural. Instead he suggests that language evolved among women. We don't spend two-thirds of our time gossiping just because we can talk, argues Dunbar—____, he goes on to say, language evolved specifically to allow us to gossip.
Dunbar arrived at his cheery theory by studying the ____ of the higher primates（灵长类动物）like monkeys. By means of grooming--cleaning the fur by brushing it, monkeys form groups with other individuals on whom they can rely for support in the event of some kind of conflict within the group or____ from outside it.
As we human beings evolve from a particular branch of the primate family, Dunbar ____ that at one time in our history we did much the same. Grouping together made sense because the bigger the group, the greater the ____ it provided; on the other hand, the bigger the group, the greater the stresses of living close to others. Grooming helped to ____ the pressure and calm everybody down.
But as the groups got bigger and bigger, the amount of time spent in grooming activities also had to be ____ to maintain its effectiveness. Clearly, a more ____ kind of grooming was needed, and thus language evolved as a kind of vocal（有声的）grooming which allowed humans to develop relationship with ever-larger groups by exchanging information over a wider network of individuals than would be possible by one-to-one ____ contact.
1.A. claim B. description C. gossip D. language
2.A. occasionally B. habitually C. independently D. originally
3.A. social B. political C. historical D. cultural
4.A. admirers B. masters C. users D. wasters

9.A. attack B. contact C. inspection D. assistance
10.A. recalls B. denies C. concludes D. confesses
11.A. prospect B. responsibility C. leadership D. protection
12.A. measure B. show C. maintain D. ease
13.A. saved B. extended C. consumed D. gained
14.A. common B. efficient C. scientific D. Thoughtful
15.A. indirect B. daily C. physical D. secret

高三英语完形填空中等难度题查看答案及解析
In recent years, a growing body of research has shown that our appetite and food intake are influenced by a large number of factors besides our biological need for energy, including our eating environment and our perception（感知） of the food in front of us.
Studies have shown, for instance, that eating in front of the TV (or a similar distraction) can increase both hunger and the amount of food consumed. Even simple visual clues, like plate size and lighting, have been shown to affect portion size and consumption.
A new study suggested that our short-term memory also may play a role in appetite. Several hours after a meal, people's hunger levels were predicted not by how much they’d eaten but rather by how much food they'd seen in front of them—in other words, how much they remembered eating.
This disparity (新旧研究的差异）suggests the memory of our previous meal may have a bigger influence on our appetite than the actual size of the meal, says Jeffrey M. Brunstrom, a professor of experimental psychology at the University of Bristol.
"Hunger isn't controlled individually by the physical characteristics of a recent meal. We have identified an independent role for memory for that meal，" Brunstrom says. "This shows that the relationship between hunger and food intake is more complex than we thought."
These findings echo earlier research that suggests our perception of food can sometimes trick our body’s response to the food itself. In a 2011 study, for instance, people who drank the same 380-calorie milkshake on two separate occasions produced different levels of hunger-related hormones （荷尔蒙），depending on whether the shake’s label said it contained 620 or 140 calories. Moreover, the participants reported feeling more full when they thought they'd consumed a higher-calorie shake.
What does this mean for our eating habits? Although it hardly seems practical to trick ourselves into eating less, the new findings do highlight the benefits of focusing on our food and avoiding TV and multitasking while eating.
The so-called mindful-eating strategies can fight distractions and help us control our appetite, Brunstrom says.
1.What is said to be a factor affecting our appetite and food intake?
A. How we feel the food we eat.
B. When we eat our meals.
C. What element the food contains.
D. How fast we eat our meals.
2.What would happen at meal time if you remembered eating a lot in the previous meal?
A. You would probably be more particular about food.
B. You would not feel like eating the same food.
C. You would have a good appetite.
D. You would not feel so hungry.
3.What do we learn from the 2011 study?
A. Food labels may mislead consumers in their purchases.
B. Food labels may influence our body’s response to food.
C. Hunger levels depend on one's consumption of calories.
D. People tend to take in a lot more calories than necessary.
4.What does Brunstrom suggest we do to control our appetite?
A. Trick ourselves into eating less.
B. Choose food with fewer calories.
C. Concentrate on food while eating.
D. Pick dishes of the right size.
5.What is the main idea of the passage?
A. Eating distractions often affect our food digestion.
B. Psychological factors influence our hunger levels.
C. Our food intake is determined by our biological needs.
D. Good eating habits will contribute to our health.

A team of researchers in the UK has shown that children who were taken to the library more often and owned more books at two years old achieved higher scores in school tests when they began primary school. The research also showed that although social background has a noticeable effect on a child’s readiness for school, attending pre-school and having their parents teach them a wide range of activities have a positive effect---while extended exposure to television lowers their scores.
“One message coming through loud and clear is that how a child learns in his very early years is critical (至关重要的) for a smooth transition into the educational system,” said Professor James Law. “This is a very positive message, as it gets us away from the belief that a child’s educational future is pre-determined by standard measures of socio-economic disadvantage, such as income, housing, or the mother’s education.”
Data from the study shows that children from a positive communication environment had a better expressive vocabulary by their second birthday. These children went on to achieve higher scores in language, reading and maths tests when they entered school. In the early years, the communication environment was a better predictor of children’s success with language than their general social background.
Most children develop speech and language effortlessly, but some are slow to acquire these skills and go on to struggle with literacy (读写能力) and academic skills throughout their schooling. This project set out to uncover what factors contributed to these problems.
Professor Sue Roulstone said, “These findings are an encouragement to all parents to provide a positive communication environment for their children from the very start of their lives. The project did identify particular aspects of the communication environment, such as having children’s books around and not having the television on too much. But the main message is that, as parents, we can have an impact on how our children learn to talk by providing a range of communication experiences. And the better our children are at talking by the age of two years, the better they will do when they start school.”
1.According to the passage, what is the most important factor contributing to children’s success at school? _____.
A. Their general social background.
B. Being taken to a library as early as possible.
C. Being involved in various activities.
D. Their communication environment.
2.From the research, Professor James Law concluded that _____.
A. children could naturally have a smooth transition into the educational system
B. the very early years had a big effect on children’s school performance
C. communication with children after they were over two years old was more effective
D. children’s educational future was pre-determined by their parents’ social position
3.The study shows that two-year-old children who have a positive communication environment do better in _____.
A. maths B. reading
C. writing D. speaking
4.What is implied in the passage? _____.
A. The research could help children who suffer from learning difficulties.
B. Parents should take their children to school as early as possible.
C. Teachers should teach children how to communicate with their parents.
D. Children who have good language abilities will not have difficulties in class.
5. People can most probably find this passage in the _____section of a website.
A. environment B. education
C. lifestyle D. Science

Researchers at the University of Kansas say that people can accurately judge 90 percent of a stranger's personality simply by looking at the person's shoes．“Shoes convey a thin but useful slice of information about their wearers,” the authors wrote in the new study published in the Journal of Research in Personality．“Shoes serve a practical purpose, and also serve as nonverbal cues （线索） with symbolic messages．People tend to pay attention to the shoes they and others wear．”
Medical Daily notes that the number of detailed personality traits （特质） detected in the study include a person's general age, income, political tendency, and other personality traits, including someone's emotional stability．Lead researcher Omri Gillath said the judgments were based on the style, cost, color and condition of someone's shoes．In the study, 63 University of Kansas students looked at pictures showing 208 different pairs of shoes worn by the study's participants．Participants in the study were photographed in their most commonly worn shoes, and then filled out a personality questionnaire．
So, what do your shoes say about your personality? Some of the results were expected: People with higher incomes most commonly wore expensive shoes, and flashier footwear was typically worn by outgoing people．However, some of the more specific results are interesting．For example, “practical and functional” shoes were generally worn by more “friendly” people, while ankle boots were more closely connected with “aggressive” personalities．The strangest of all may be that those who wore “uncomfortable looking” shoes tend to have “calm” personalities．
And if you have several pairs of new shoes or take exceptional care of them, you may suffer from “attachment anxiety,” spending too much time worrying about what other people think of your appearance．There was even a political calculation in the mix with wearing “shabbier and less expensive” shoes．
The researchers noted that some people will choose shoe styles to mask their actual personality traits, but researchers pointed out that volunteers were also likely to be unaware that their footwear choices were revealing deep insights into their personalities．
1.By looking at a person’s shoes, it’s possible for people to_____．
A．know the wearer thoroughly and accurately

3.Taking exceptional care of new shoes shows that _____．
A．the owners care much about others’ opinions on their appearance
B．the owners are in a relaxed state
C．the owners are particular about their appearance
D．the owners have too many shoes to choose from

The strangest of all may be that those who wore” uncomfortable looking” shoes tend to have “calm” personalities. And if you have several pairs of new shoes or take extreme care of them，you may suffer from“attachment anxiety”，spending lots of time worrying about what other people think of your appearance. There was even a political calculation in the mix with more liberal(主张变革的)types wearing” shabbier and less expensive” shoes.
The researchers noted that some people will choose shoe styles to mask their actual personalities，but researchers noted that volunteers were also likely to be unaware that their footwear choices were showing the deep side of their personalities.
