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.
When I was a child, I had to go to church and obey many other rules, though these rules at times caused resentment (怨恨). Perhaps the most extreme parenting decision my parents made for my four brothers and sisters and me was to create a home environment without a television.
We hated this decision at that time, because there was seemingly no way to keep this embarrassing fact a secret at school. Naturally, simple pleasures like cartoons, football games, and movies became huge novelties (新奇事物). I would go over to friends' or relatives' houses for that access alone.
When I reached high school, my parents bought a television, though it had no cable. However, I did spend most of my childhood in a home without a television. In fact not having a television did contribute a great deal to my skills, and it also forced me to develop other valuable interests. We grew up in a small town, so my brothers and sisters and I spent time exploring streets, fields and woods. And of course I read and wrote and studied, which pushed me toward a career path.
So would I give a similar situation to my own children if I had them? I doubt it, at least not in the most extreme sense. I'm too much of a football fan, not to mention the TV serials (连续剧) like The Wire. But television or almost anything for that matter is unhealthy for kids. It can prevent them from living a full life. So maybe a reasonable answer is no cable or no video-game systems or simply setting the time limit, but I haven't exactly worked out how to confine it yet. Although some people are against my idea, we do need limits after all.
The teenage years can be tough, and it's normal to feel sad every now and then. But if these feelings don't go away or become so intense that you can't handle them, you may be suffering from depression.
Try not to isolate yourself.
When you're depressed, you may not feel like seeing anybody or doing anything. Just getting out of bed in the morning can be difficult, but isolating yourself only makes depression worse.Spend time with friends, especially those who are active.
Keep your body healthy.
Making healthy lifestyle choices can do wonders for your moods. Ever heard of the "RunnersHigh"? Physical activity can be as effective as medications for depression, so get involved in sports, ride your bike, or take a dance class. Any activity helps!As for food, make sure you're feeding your mind with plenty of fruits, vegetables, and whole grains.
Avoid alcohol and drugs.
You maybe try drinking or use drugs in an effort to escape from your feelings and get a "mood boost", even if just for a short time. However, substance use can make depression worse.You will need special treatment for your substance abuse problem.
Stress and worry can lead to depression. Talk to a teacher if exams or classes seem overwhelming. In addition,if you have a health concern you feel you can't talk to your parents about, see a doctor. A health professional can help you approach your parents and guide you toward appropriate treatment. If you're dealing with relationships, friendships, or family problems, talk to an adult you trust.
A. Ask for help if you are stressed.
B. Even a short walk can be beneficial.
C. Turn to your parents for help.
D. As you get out into the world, you may find yourself feeling better.
E. In short, drinking and taking drugs will make you feel worse — not better — in the long run.
F. The more exercise you do, the healthier you will be.
G. Help is available and you have more power than you think.

It's not the people you came across in your daily life who will stand by you in time of a need. It's your family who will but it's important to know that. It happens such often that we end up take our parents for granted. We hurt them many cases and they are treated with disrespect for not understanding them. It's necessary to understand the fact that there is always different in opinions across two generations. But what really matters is the unconditionally love and care that they hold for us, that I believe is truly valuable.
We think that life in Chinese high school is an adventure in which we have to survive mountains of homework and all kinds of exams. Yet would it be(surprise) if I tell you that high school life in the US is almost as stressful and demanding as it is in China?
In US high school, everything(record) into your studying document, including your grades on quizzes, tests and final examinations. Failing(turn) in your homework on time will directly affect your grade for a certain course. Perhaps contrary towe used to think of the US high school students, they pay more attention to their(academy) performance to try to get into a distinguished university., they'll be disappointed after graduation from high school.
Like university students, US high school students have the(free) to choose the courses that most interest(they). Even a ninth grader can sitthe same classroom as twelfth graders. But this also means he or she has to work very hard, because the teacher will not treat him or her differently just because he or she is a few years(young).
