Not long ago, the only time you could see a robot was when you were reading a novel or watching a movie such as Star Wars (星球大战) . Today, however, a lot of things in science stories have been science facts. Robots are starting to appear in our everyday lives. These robots have different sizes, shapes, and colors. But they all have the same type of man-made “brain”. Leading the robot revolution （革命）are industrial(企业) robots that work in factories. Industrial（工业） robots can do different kinds of jobs that are often boring and sometimes dangerous. Robots are also coming to American homes, though not as quickly as they are entering factories. These robots aren’t as friendly and bright as those you saw in Star Wars. But, their makers say, today’s home robots “walk”, sense objects(感知物体) in their way (and sometimes knock into them), and even carry objects (which they sometimes drop). Well, nobody is perfect.
We may laugh at home robot today, but some day they may see and hear better than humans do. We humans can only see certain wavelengths（波长） of light, and hear certain sounds. That’s because the abilities of our eyes and ears are limited. Robots, however, need not have the same limits as we have. Robot may also be equipped with devices that pick up information humans can’t. To understand what their sensing devices(传感器) pick up is a hard job. Remember, man—made brains handle(处理)information, including all kinds of data, as zeroes and ones. Imagine the difficulty in trying to explain to a robot what a football looks like—using only zeroes and ones.

Americans think much about time. Form childhood they learn to value (珍视)
time. They are taught to be on time to go to school, to work and to do everything. When they are having a good time, they say that time goes easily. When a person is dying, they say he is living on a borrowed time.
Time is money. Time is knowledge. Time is everything in America. A working American has to work hard for eight hours a day or forty hours a week. This is the working time. In his free time, he also works hard for more money. Even on Saturday and Sunday he also works hard as usual. In the street you can hardly see a man walking slowly. They walk very fast. In fact, they are running.

Height is just one of the thousands of features your genes decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall, too, but if you have questions about how tall you’re going to be, ask your doctor if he or she can help you find it out.
But genes don’t decide everything. For example, eating an unhealthy diet can keep you from growing to your full potential(潜力). Getting plenty of sleep and enough exercise will help you grow to the expected height.
No doubt you’re wondering how fast you should grow. It depends. There’s no perfect or right answer. Generally speaking, kids grow about 2 inches (6 centimeters) a year between age 3 and the time when they start puberty (when your body starts changing and becoming more grown up).
Your doctor will know how your growth has been going over the years. Two centimeters here and 2 inches there are not nearly as important as the height you’re at now, how you’ve been growing up to this point, and what other changes your body may be going through.
Don’t be scared if you seem to have grown a lot in a very short time. Everyone has a growth spurt（高峰）during puberty. The age for starting puberty is about 10 for girls and about 11 for boys. But it can be earlier or later ----between 7 and 13 for girls and 9 and 15 for boys.
You’ll usually begin to notice that you’re growing faster about a year or so after your body starts to show the first changes of puberty.

If someone is lost in a forest( 森林 ), he needs only study the trees around him carefully to find his way. On this half of the earth, he will find that the side of the tree with the most leaves and branches(树枝 ) is the south side. Also, by checking the tops of the trees, he will find that they lean(倾斜 ) to the south too.
Another sign( 标志物) for him to know where he is going is found in the bark.( 树皮) That is brighter on the south side.The remanining(树桩 ) of a cut tree is also a finder, for its rings can give him another sign. The rings will be thinner on the south side and thicker on the north side.

The Bermuda Triangle(百慕大三角)is in the Atlantic Ocean, near Florida in the USA. During the past 60 years, more than 1,000 seamen in ships and pilots in planes have lost their lives. It is known as “The Triangle of Death”for its strange seawater and sudden storms. What’s the strangest is the light of the seawater, which looks so bright that it can be seen even from an outer spaceship.
At 2:00p.m. on Dec. 5, 1945, five planes took off in fine weather from the airport of Florida, on a training task. Two hours later, the leader in the sky radioed that he was “completely lost”. Then there was silence. Another plane was sent to look for them and also disappeared.
One of the largest ship that had disappeared in the triangle was an American coal ship, 500meters long. The weather was good, and there were no messages for help before it was “gone”. No broken ships or dead bodies have been found so far.
No one is able to tell how all these accidents have happened. A group of Japanese scientists were there to see what it was really like in 1995, but nothing has been heard of them ever since.
