单选题Imagine, if you will, the average games player．What do you see? A guy who never grew up? Or a nervous 18-year-old pushing buttons on his controller, lost and alone in a violent onscreen world?Sorry,you lose．The average garner is starting to look pretty much like the average person．For the first time, according tO a U.S．poll commissioned by AOL(American On Line)Games, roughly half of those surveyed, ages 12 to 55, are tapping away at some kind of electronic game—whether on a PC, a cell phone or another handheld device—for an average of three hours every week． The games people play say a lot about who they are．Machines like the Xbox and PlayStation 2 are largely the territory of twenty—something men, who prefer to picture themselves as sports stars and racing drivers．Men 50 and older prefer military games． Teenage girls are much more likely than boys to play games on their phone, while older women make up the majority of people playing card games such as Hearts online． Is it a good thing，all this time spent on games? Or is it as harmful as television，pulling people ever further from reality?The AOL survey suggests some players are in denial about the extent of their habit．One in 10 garners finds it is impossible to resist games; 1 in 4 admits to losing a night's sleep to play games; and another quarter has been too absorbed to have meals． But don't think we're all heading into a world with everyone plugged into, if not totally controlled by, his own game．Quite the contrary: gamers appear to be more engaged with reality than other kinds of couch potatoes．According to a comprehensivesurvey by the Entertainment Software Association(ESA—whose members, of course， want you to think video games are healthy), gamers spend an average of 23 hours a week volunteering and going to church, concerts, museums and other cultural events． More enthusiastic gamers who play 11 hours a week or more spend even more time out in the cultural world (34 hours)．

单选题There were two widely divergent influences on the early development of statistical methods. Statistics had a mother who was dedicated to keeping orderly records of governmental units (state and statistics come from the same Latin root, status) and a gentlemanly gambling father who relied on mathematics to increase his skill at playing the odds in games of chance. The influence of the mother on the offspring, statistics, is represented by counting, measuring, describing, tabulating, ordering, and the taking of censuses—all of which led to modern descriptive statistics. The influence of the father came modern inferential statistics, which is based squarely on theories of probability. Descriptive statistics involves tabulating, depicting, and describing collections of data. These data may be either quantitative, such as measures of height, intelligence, or grade level—variables that are characterized by an underlying continuum—or the data may represent qualitative variables, such as sex, college major, or personality type. Large masses of data must generally undergo a process of summarization or reduction before they are comprehensible. Descriptive statistics is a tool for describing or summarizing or reducing to comprehensible form the properties of an otherwise unwieldy mass of data. Inferential statistics is a formalized body of methods for solving another class of problems that present great difficulties for the unaided human mind. This general class of problems characteristically involves attempts to make predictions using a sample of observations. For example, a school superintendent wishes to determine the proportion of children in a large school system who come to school without breakfast, have been vaccinated against flu, or whatever. Having a little knowledge of statistics, the superintendent would know that it is unnecessary and inefficient to question each child; the proportion for the entire district could be estimated fairly accurately from a sample of as few as 100 children. Thus, the purpose of inferential statistics is to predict or estimate characteristics of a population from a knowledge of the characteristics of only a sample of the population.

单选题Shyness is the cause of much unhappiness for a great many people. Shy people are anxious and self-conscious; that is, they are excessively concerned with their own appearance and actions. Worrisome thoughts are constantly occurring in their minds: What kind of impression am I making? Do they like me? Do I sound stupid? Am I wearing unattractive clothes? It is obvious that such uncomfortable feelings must affect people adversely. A person's self-concept is reflected in the way he or she behaves, and the way a person behaves affects other people's reactions. In general, the way people think about themselves has a profound effect on all the areas of their lives. Shy people, having low self-esteem, are likely to be passive and easily influenced by others. They need reassurance that they are doing "the right thing". Shy people are very sensitive to criticism; that they feel it confirms their inferiority. They also find it difficult to be pleased by compliments because they believe they are unworthy of praise. A shy person may respond to a compliment with a statement like this one: "You're just saying that to make me feel good. I know it's not true. "It is clear that, while self-awareness is a healthy quality, overdoing it is harmful. Can shyness be completely eliminated, or at least reduced? Fortunately, people can overcome shyness with determined and patient efforts in building self-confidence. Since shyness goes hand in hand with lack of self-esteem, it is important for people to accept their weaknesses as well as their strengths. For example, most people would like to be "A" students in every subject. It is not fair for them to label themselves inferior because they have difficulty in some areas. People's expectations of themselves must be realistic. Living on the impossible leads to a sense of inadequacy. Each one of us is a unique, worthwhile individual. We are interested in our own personal ways. The better we understand ourselves, the easier it becomes to live up to our full potential. Let's not allow shyness to block our chances for a rich and fulfilling life.

单选题What exactly is a lie? Is it anything we say which we know is untrue? Or is it something more than that? For example, suppose a friend wants to borrow some money from you. You say, "I wish I could help you but I'm short of money myself." In fact, you are not short of money but your friend is in the habit of not paying his debts and you don't want to hurt his feelings by reminding him of this. Is this really a lie? Professor Jerald Jellison of the University of Southern California has made a scientific study of lying. According to him, women are better liars than men are, particularly when telling a "white lie", such as when a woman at a party tells another woman that she likes her dress when she really thinks it looks awful. However, this is only one side of the story. Other researchers say that men are more likely to tell more serious lies, such as making a promise which they have no intention of fulfilling. This is the kind of lie politicians and businessmen are supposed to be particularly skilled at the lie from which the liar hopes to profit or gain in some way. Research has also been done into the way people's behavior changes in a number of small, apparently unimportant ways when they lie. It has been found that if they are sitting down at the time, they tend to move about in their chairs more than usual. To the trained observer they are saying: "I wish I were somewhere else now." They also tend to touch certain parts of the face more often, in particular the nose. One explanation of this may be that lying causes a slight increase in blood pressure. The up of the nose is very sensitive to such changes and the increased pressure makes it itch. Another gesture which gives liars away is what the writer Desmond Morris in his book. Man watching calls "the mouth cover". He says there are several typical forms of this, such as covering part of the mouth with the fingers, touching the upper-lip or putting a finger of the hand at one side of the mouth. Such gesture can be understood as an unconscious attempt on the part of the liar to stop himself or herself from lying. Of course, such gestures as rubbing the nose or covering the mouth, or moving about in a chair cannot be taken as proof that the speaker is lying. They simply tend to occur more frequently in this situation. It is not one gesture alone that gives the liars away but a whole number of things and in particular the context in which the lie is told.

单选题The banana "tree" is actually not a real tree. This is because there is no wood in the stem(树干) rising above the ground. The stem is made up of leaves growing very close together, one inside the other. The leaves spread out at the top of the stem and rise in the air. Banana plants need a lot of care and attention. They must be provided with water if the normal rainfall doesn't supply enough. The area around the plants must be kept free of weeds and grass. About nine or ten months after planting, a flower appears on the banana plant. This flower is at the end of a long stalk(茎), which grows from the base up through the center of the stem and turns downward when it comes out from the top. Small bananas form on this flower stalk as it grows down- ward. Bananas really grow upside down. As the small bananas form on the stalk, they point down- ward, but as they grow they mm and point upward. Bananas are harvested while they are still green. Even when they are to be eaten where they are grown, they are not allowed to ripen on the plant. A banana that turns yellow on the plant loses its taste.
