Woodblock printing first appeared in the early Tang period. During the Song dynasty, the technique of block printing was very advanced. Books were (beautiful) printed. Even today the books(print) at the time are valuable and treasured by libraries and book collectors.
However, block printing (be) not very convenient. Every two pages of a book had to be carved on a woodblock, and a big book would require many blocks. Besides, there had to be large places for storing the books. (overcome) these shortcomings, Bi Sheng invented the movable type during the years between 1041 and 1048. One word was carved on one piece of clay, was hardened with fire. Then clay characters were set on iron plate according to the text of a book. Then ink was applied to them and (sheet) of paper spread over them, and the printing was done. Bi Sheng's invention made printing faster and (easy) than before. Later, movable type of metal and wood was made and widely used.
The technique of printing was gradually known to other Asian countries and Europe. The great influence printing had the advance of civilization is too clear to need any (explain).
Professor Martin's report says that children who attend a number of schools, because their parents have to move around the country, probably make slow progress in their studies. There are also signs, says Professor Martin, that an unusually large number of such children are mentally affected.
The professor says, "It's true, my personal feeling is that children should stay in one school. Our feelings are based on research and not on any personal feeling that I or many assistants may have on the subject."
Captain Thomas James, an army lecturer for the past 20 years and himself a father of two, said, "I've never heard such rubbish. Taking me for example, no harm is done to the education of my children who change school regularly—if they keep to the same system, as in our Army school. In my experience—and I've known quite a few of them—Army children are as well-adjusted (适应) as any others, if not better. What the professor doesn't appear to appreciate is the fact that in such situations children will adapt (适应) much better than grown-ups."
When this was put to Professor Martin, he said that at no time has his team suggested that all such children were backward or mentally affected in some way, but simply that in their experience there was a clear tendency (倾向).
"Our findings show that while the very bright child can deal with regular changes without harming his or her general progress in studies, the majority (大多数) of children suffer from constantly (不断地) having to enter a new learning situation."
"Depend on yourself" is what nature says to everyone. Parents can help you. Teachers can help you. Others can help you. But all these only help you to help yourself.
There have been many great men in history. But many of them were poor in childhood, and had no uncles, aunts or friends to help them. Schools were few and not very good. They could not depend on them for education. They saw how it was, and set to work with all their strength to know something. They worked their own way till they became wellknown.
One of the most famous teachers in England used to tell his pupils, "I can not make worthy men of you, but I can help you make men of yourselves."
Some young men do not try their best to make themselves valuable to the human beings. They can never gain achievements unless they see their weakpoints and change their courses. They are nothing now, and will be nothing as long as they live, unless they accept the advice of their parents and teachers, and depend on their own honest efforts.
Terry, who failed again and again in career (事业), often complained that he had been cheated by others. One day he told his wife he was so (disappoint) with the city that he had to leave.
It was the evening of weekend when they moved to another city. Terry and his wife (tidy) up their new home busily when the light suddenly went out. Terry was regretful to have forgotten bringing along candles and had to wait (help) in a low mood. Just then he heard knocks on his door. Wondering who it was, Terry, a newcomer to this city, went to the door and opened it impatiently. the door was a little girl, shyly asking whether he had candles. "No" Terry answered in anger and shut the door (violent).
After a while, the girl knocked again. this time she was holding two candles, saying, "My grandma told me the new neighbour downstairs might need candles. She sent me here to give you these." Terry was very (surprise) by what he saw.
At that moment he suddenly realized what caused his (repeat) failure in life. The person who had cheated him in life was really nobody else but (him).
It's best to plan ahead and there is no better way than to prepare for an emergency before it happens. For example, the time to plan for a fire emergency is before it happens. This is when everyone is calm and clear-thinking. This is when decisions about safe escape routes can be discussed and made. Have a family talk. Don't delay. Planning won't help after a fire starts.
Knowing ahead of time how to get out during a fire can save needed seconds. The best way out in a fire is the route you use to go in and out every day. Yet, in a fire this route may be blocked. Be sure to plan other escape routes.
Take each person to his or her room and describe what to do in case of fire. Give everyone a job. Older children should take care of younger ones. Plans may have to be made for anyone who cannot escape without help. Adults who can't walk should sleep on the first floor. Small children should sleep near older persons who can help them. Only healthy, able persons should sleep in hard-to-reach places such as attics or basements.
Practice your escape plan at night when it is dark. Be sure that your plan is good and will work. For example, make sure that a child can actually open the window he is supposed to use for his escape. Teach children to close their bedroom doors. Tell them to wait by an open window until someone can reach them from outside. If an adult cannot be wakened, children should understand that they must leave by themselves.
Choose a meeting place outside. This way you can tell if everyone is safely out of the building. Know where nearby telephones or fire alarm boxes are found.
If you live in an apartment, try to get everyone out. Learn where the fire alarm is in the building. Your family should know what the fire alarm bell sounds like. They should know what to do when they hear it. Try to get the other families in your building together to have fire drills. Write down the telephone number of the fire department. Stick the number to each phone.
Early warning is the key to a safe escape. It has been shown time and time again that a family can escape if warned early enough.
Any car accident is frightening, but an accident in which your vehicle is thrown into the water, with you trapped inside, is absolutely terrifying. However, most deaths result from panic, without a plan or understanding what is happening to the car in the water. By adopting a brace(支撑) position, acting decisively and getting out fast, you can save yourself from a sinking vehicle.
Brace yourself for impact. As soon as you're aware that you're going off the road and into a body of water, adopt a brace position. The impact could set off the airbag system in your vehicle, so you should place both hands on the steering wheel in the "ten and two" position.
Undo your seat belt. Untie the children, starting with the oldest first. Forget the cellphone call. Your car isn't going to wait for you to make the call.
Leave the door alone at this stage and concentrate on the window. A car's electrical system should work for up to three minutes in water, so try the method of opening it electronically first. Many people don't think about the window as an escape option either because of panic or misinformation about doors and sinking.
Break the window. If you aren't able to open the window, or it only opens halfway, you'll need to break it with an object or your foot. It may feel counter-intuitive (与正常预期相反的) to let water into the car.
Escape when the car has equalized. If it has reached the dramatic stage where the car cabin has been filled with water and it has become balanced, you must move quickly and effectively to ensure your survival. While there is still air in the car, take slow, deep breaths and focus on what you're doing.
A. Open the window as soon as you hit the water.
B. Surviving a sinking car is not as difficult as you think.
C. It takes 60 to 120 seconds for a car to fill up with water usually.
D. Such accidents are particularly dangerous to the risk of drowning.
E. In conclusion, if you know what to do in the water, you will be safe.
F. This is the first thing to attend to, yet it often gets forgotten in the panic.
G. But the sooner the window is open, the sooner you can escape directly through it.
If someone asked you to quantify (衡量) the time you spend online, how would you answer? If you're like one-fifth of Americans, you'd likely say "almost constantly." New research shows that 21 percent of Americans report that they're online more or less constantly.
Andrew Perrin, a research assistant at Pew, did a survey about Internet use. During the survey, adults were asked how much they go online. 13 percent said they don't go online and 13 percent said they go online several times a week or less. Only 10 percent said they go online once a day and much larger quantities said they go online several times a day (42 percent) or "almost constantly" (21 percent).
Interestingly, there wasn't a gender split (性别分化) when it came to near constant Internet use. Age seems to be the great divider: Only six percent of people over 65 said they were online that much. Those who reported that they were online all the time included 12 percent of 50- to 64-year-olds, 28 percent of 30- to 49-year-olds and 36 percent of 18- to 29-year-olds.
Don't suppose that teenagers are online more than adults, however. In another survey, Pew found that while they did have a slight edge on adults in general when it came to "almost constant" Internet use, 24 percent said they were online pretty much all the time. They still fell greatly behind the 36 percent of adults between 18 and 29 years of age who were always online.
Given that the United Nations considers unrestricted (无限制的) Internet access (接入) to be a human right, the number of Americans who report being online "almost constantly" could rise along with availability and affordability. But it remains to be seen whether being online all the time is actually something to long for, or how constant connectivity will affect American culture in the long term.

The sun was setting and the farm would be closing soon. I dressed our three daughters quickly as my husband started the car. Cutting down our own Christmas tree had been a family tradition.
As we walked through the rows of trees, my youngest daughter Kimberly shouted excitedly, "There it is, the perfect tree!" The other two agreed. My husband and I looked at each other puzzled. It was misshapen and pine needles were missing here and there.
We tried to talk our daughters into changing their minds, but failed. We had to tie the tree to the top of our car and headed home. As we reached our house, Heather jumped out first. Suddenly she shouted, "The tree isn't there!" We thought she was kidding. However, it wasn't there.
The girls were so sad. "We'll get another tree tomorrow, "I said, secretly hoping the new tree would be prettier. But the girls gave us the look that no parent can say no to. We had no choice but to go back and find that tree.
About five minutes into our drive, we saw our tree on the side of the road. Clearly it had been run over by a truck and a big part of it had fallen off, but we took our little broken tree home anyway.
Once at home, we all agreed that the flat broken side would go up against the wall. That night, as we decorated our tree, something magical happened. By the time we were done, I had to admit, it didn't look sad after all. "This is the best tree we ever had. It's perfect!" my second daughter Samantha said excitedly. My husband and I couldn't have agreed more!
Now we always recall that little broken tree! Year by year, we tell the story of that very special Christmas almost twenty-five years ago.
