There is much discussion about the necessity of daily homework for students. Some say homework is necessary since only practice 1. (make) perfect, while others disagree. In my opinion, daily homework is necessary for students. However, this might be misleading that one may believe all forms of homework 2. necessary. Actually , only proper amount of homework in proper form is 3. ( accept); some homework may not only fail to help the students, but on 4. contrary bore them so much that they may lose their interest in studying. “Proper” homework, in my opinion, should 5. (vary) in its forms, 6. might be some extensive reading, a paper, or even just a game, as well as other ordinary exercise. And it should leave enough 7. (free) to the students so that they could do things they really like to do with self-motivation, rather than unwillingness. We should always remember that homework is something for us to guide the students, rather than 8. (drive) them. Only if a teacher 9. (keep) this 10.his/her mind, the homework could be of most help to the students.
We often see hitchhikers（搭便车的人）, standing by the side of the road, thumb sticking out, waiting for a lift. But it is getting nowadays. What killed hitchhiking? is often mentioned as a reason. Movies about murderous hitchhikers and real-life crime many drivers off picking up hitchhikers. no single women picked me up on my journey to Manchester reflects the safety fear: , strangely dressed man is seen as dangerous.
But the reason may be complex: hitchhiking happens where people don’t have cars and transport services are . Plenty of people hitchhike in Poland and Romania. Perhaps the rising level of car ownership in the UK means the few people lift hitchhiking are usually considered strange. Why can’t they cars? Why can’t they take the coach or the train?
Three-quarters of the UK population have a car; many of the will be quite old. The potential hitchhiking population is therefore small. my trip proves it’s still possible to hitchhike. The people who picked me up were very interesting lawyer, retired surgeon, tank commander, carpenter, man who live in an isolated farmhouse and a couple in the mountains. My conclusion is that only really interesting people are mad enough to pick up fat blokes(家伙) in red, spotted scarves. Most just wanted to do someone a good turn; a few said they were so surprised to see a hitchhiker that they couldn’t help .
The future of hitchhiking most lies with car-sharing organized over the Internet, via sites such as hitchhikers. org. But for now, you can still stick your thumb out (actually, I didn’t do much of that, just to hold up my destination sign) and people—wonderful, caring, sharing, unafraid people—will stop.
In the UK, with its cheap and reasonable rail service, I don’t think I’ll make a habit of it. But having enjoyed it so much, I’m ready now to do a big trip Europe and beyond. In the 1970s a female friend of my wife’s hitchhiked to India. How wonderful it would be to have another go, Afghanistan might be a challenge. I wish I’d got that tank commander’s mobile number.

Three-dimensional printers are fast becoming everyday devices in the United States. Three-D printers are used to make everything from automobile parts to bone replacements for human patients. American research scientists are now working on creating replacements for living tissue.
Researchers at the Medical University of South Carolina have been working on creating and manufacturing living tissue since 2003．This process is called biofabrication (生物制造) . It requires special printing equipment and a special kind of ink.
Traditional printers require ink to produce an image or design on a piece of paper. For their three-D printer, the South Carolina researchers prepare complex nutritious solutions they call bio-inks. Bio-inks are made of proteins and glucose (葡萄糖) , which normally provides energy for most cells of the body. The researchers also add living cells taken from the animal that will receive the new, printed tissue. The bio-inks are then added to a device that researchers call the Palmetto bio-printer.
Sarah Grace Dennis is one of the researchers at the Medical University of South Carolina. She says new technology, like the Palmetto bio-printer, is a great help to the biofabrication process.
The bio-inks are placed in three dispensers (分配器) , containers, inside the printer. Lasers control both the position of the printing surface and the places where the bio-ink is released.
Michael Yost is a leader of the research team. He says the printing process is fully automated— machine-operated. He says that the Palmetto bio-printer makes it possible to create complex tissue types.
The researchers say bio-printing is still experimental. But they hope in a few years they may be able to print tissue to replace damaged human organs.
But there are still some problems which need to be solved. Some scientists worry about how to get blood to the replacement tissue. The flow of blood is important to keep the printed tissue alive.
Michael Yost hopes that more people will believe in the benefits of biofabrication.
“Tissue biofabrication is a reality, and it is a reality now, and if you come here and you get to see it. You will get to see it. You can’t touch it, but you will see it and think this is real. And this is really human.”

Your kids learn a lot from their friends—things you can’t teach them, no matter how much you
want to.
Probably the most important thing kids learn is how to have peer relationships. As a parent, you can’t do this, because you and your child aren’t equals.
For example, when you’re sitting on your family room floor and your very young child asks you to pass him the blocks, you probably hand them right over. If your child is sitting with a peer and asks the same thing, though, he might not get what he wants.
To succeed, your child will need to learn strategies for getting what he wants. For example, he might simply yank (猛拉) the toy out of his friend’s hand. If he does that, he may learn that it’s not the best way of getting what he wants because it leads to fighting and time-outs. The successful child will learn that he needs to negotiate a trade, to wait patiently, or to find something else equally fun to play with.
Friends also provide emotional support, something that is part of the foundation of healthy adulthood. You can’t be with your child on the elementary school playground or at the high school dance. Your child’s friends will be the ones to stick up for her, to include her in games, and later, to tell her she looks great even if her lousy prom (糟糕的舞会) date wanders off instead of dancing with her.
Friends also help your children learn. Friends solve problems together, imitate each other, and
pass on knowledge .
Some experts believe that the single biggest predictor of your child’s success later in life is her ability to make friends. In fact, they claim it’s even more important than IQ and grades.
This doesn’t mean that the kids who are most popular in school do the best later on in life. What matters is not the number of friends a child has but rather the quality of the relationships.
This is good news for those of us who hate to think that popularity really is the Holy Grail of childhood and adolescence. While it’s true that popularity has many advantages, and that many popular kids really are nice people—and not just the best dressed or best looking—it’s better to have a few good friends than to have the admiration of the masses.
