    Today just as technology changed the face of industry, farms have undergone an "agricultural revolution". On the farm of today, machines provide almost all the power.

    One of the most important benefits will be the farm computer. The computers help them keep more accurate records so they can make better decisions on what crops to plant, how much livestock (家畜) to buy, when to sell their products, and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. In the future, farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm, students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers even more in the future. While the old-time farm depended on horse power, and modern farms depend on machine power, farms of the future will depend on computer power.

    Another technological advance which is still in the experimental stage is the robot, a real "mechanized hired hand" that will be able to move and, in some ways, think like a human being. Agricultural engineers believe that computer-aided robots will make big changes in farming before the end of the century. Unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to drive tractors, and harvest fruit. Even complex jobs will be done by robots. For example, in order to milk their cows, farmers must first drive them into the barn, then connect them to the milking machines, watch the machines, and disconnect them when they are finished. In the future, this will all be done by robots. The complete mobilization (活动) of the farm is far in the future, but engineers expect that some robots will be used before long.

(1)、According to the passage, computers cannot help farmers decide _______.
A、how much money they can earn from their products B、whether to plant a certain kind of crop C、what livestock to raise D、when to sell their products
(2)、Which of the following statements is true?
A、Farmers in the future will depend totally on computers. B、Both computers and robots have been in use on today's farms. C、Farmers mainly use machines on their farms at present. D、Students at agricultural colleges must take computer classes because they can do nothing without them.
(3)、According to the engineers, what will be done by robots in the near future?
A、All farm work. B、Milking cows. C、Some farm work. D、Most of the farm work.
(4)、What is the best title for the whole passage?
A、Computer, Farmers' Best Friend B、Farmers in The Future C、Computers and Robots D、The Agricultural Revolution

Finding the Real You

    Psychometric testing—personality testing—has been very popular nowadays as studies show their results to be three times more accurate in predicting your job performance. These tests are now included in almost all graduate recruitment (招聘) and are widely used in the selection of managers.

    The most popular of these personality tests is the Myers-Briggs Type Indicator (MBTI). It is based on the theory that we are born with a tendency to one personality type which stays more or less fixed throughout life. You answer 88 questions and are then given your “type”, such as Outgoing or Quiet, Feeling or Thinking.

    Critics of personality testing raise doubts about “social engineering”. Psychologist Dr. Colin Gill warns that the “popular” personality traits (特性) have their disadvantages. “People who are extremely open to new experiences can be butterflies, going from one idea to the next without mastering any of them.” However, the psychometric test is here to stay, which may be why a whole sub-industry on cheating personality tests has sprung up. “It's possible to cheat,” admits Gill, “but having to pretend to be the person you are at work will be tiring and unhappy and probably short-lived.”

    So can we change our personality? “Your basic personalities fixed by the time you're 21,”says Gill, “but it can be affected by motivation and intelligence. If you didn't have the personality type to be a doctor but desperately wanted to be one and were intelligent enough to master the skills, you could still go ahead. But trying to go too much against type for too long requires much energy and is actually to be suffered for long. I think it's why we're seeing this trend for downshifting—too many people trying to fit into a type that they aren't really suited for.”

    Our interest in personality now exists in every part of our lives. If you ask an expert for advice on anything, you'll probably be quizzed about your personality. But if personality tests have any value to us, perhaps it is to free us from the idea that all of us are full of potential, and remind us of what we are. As they say in one test when they ask for your age: pick the one you are, not the one you wish you were.

    Organic exercise is a good fit for people looking to train functionally. It is defined as exercise that is similar to the type of physical activity performed by ancient hunter-gatherer ancestors. Organic exercise is generally preformed in natural or outdoor settings. {#blank#}1{#/blank#} Organic exercise may include such activities as walking, jogging, swimming, hiking or rock climbing.

    {#blank#}5{#/blank#} Individuals who are new to exercise may want to talk with their health care provider before choosing this type of activity.

    E-mail systems at thousands of companies and government offices around the world were attacked by a virus(病毒)called “Melissa” that disguises(伪装)itself as an “important message from a friend. In spite of a weekend of warnings,more than 50 000 computers at about 100 places around the world have been attacked by the virus,computer security experts said on Monday.

    The virus began to show up last Friday and spread rapidly on Monday by making computers fire off dozens of infected(被传染的)e-mails. Although the virus causes no serious damage to a computer,its effect was far reaching.

    To make matters worse,a similar virus called “Papa” was discovered on Monday. Papa is programmed to send out even more infected e-mails than Melissa.

    The Melissa virus comes in the form of an e-mail,usually containing the subject line“Important Message”. It appears to be from a friend. The body of the e-mail message says,“Here is that document you asked for...,don't show it to anyone else.” Attached(附)to the message is a document file.

    Once the user opens that file,the virus digs into the user's address book and sends infected documents to the first 50 addresses. E-mails from the Papa virus include an attached spreadsheet(电子数据文件)file. When the user opens that file,the virus sends 60 infected e-mails.

    The reason why this is spreading so fast is that you are getting it from people you know. You should never open documents or attachments from people you don't know. People who get an unexpected e-mail with the “important message” subject line should delete it immediately and not open the message.

    Here's the bad news: Men are hurting, and, according to many researchers. masculinity (男子气) is what is hurting them and making it hard for them to maintain friendships. Society tells men to hide their feelings and expects them to be aggressive, so many men lose their friendship when growing up. The good news is that those skills can be recovered!

    There are a lot of experts who can help. and here's what they recommend:

    ⒈Accept your own desire and normalize it for the people in your life. Way, an expert, recommends sharing articles about masculinity and friendship so that you can start these conversations! Concentrate on them and don't forget you have the entire Internet at your fingertips, friend!

    ⒉Model vulnerability. Say the thing that frightens or worries you. like "I'm afraid nobody will go to my party," or "I miss my grandma every day." Doing so will make it easier for other people to follow your lead. We are all on the elevator to a society where emotional availability is normalized, and I want you to press "door open".

    ⒊Ask more questions. People sometimes feel they might be prying (爱打听的) if they ask someone about themselves-especially when their friend is sharing something tough. But if you get curious in moments of vulnerability you will open the door to all kinds of growth in your relationship. Take the opportunity to really see your friend and show them they matter by following up.

    ⒋Get close with the children in your life. Way's research says that the top priority that helps children (especially boys) grow up to have enriching friendships is to be close with an adult relative who was not afraid to express emotions. So. if you are a father. stepfather. or thinking about becoming one. or if you have nieces or nephews, take the opportunity to be close to them and help them grow up to be good friends, too.
