Nowadays science has made great progress in every aspect and more and more really good inventions have changed our daily lives. However, the U.S. Patent Office has issued over 7.5 million patents (专利), and not all of them are quite so celebrated. Some good, some bad, and some crazy! The following lists some of the most unusual ideas that have come along.
Snake Leash (皮带)
In 2002, a patent was issued for a snake-walking leash. There are at least two major problems with this idea. 1) Dog leashes fit securely between the head and shoulders. A snake does not have shoulders; so it might slither (蜿蜒滑行) away. 2) Dogs are OK for public places because they are social animals, and people like them. Snakes are not OK for public places because they are not social, and some people are terrified of them.
Stadium Helmet
Americans are known for their love of sports. Unfortunately, good tickets to games are expensive, so some fans have to sit in the backward sections. This invention, patented in 2000, is designed for these fans. Featuring a built-in radio, binoculars (望远镜), a cooling fan, and a helmet for falling litter, this design transforms the stadium experience.
Bacon Alarm Clock
When you think about it, waking to the dreadful, blaring noise of an alarm clock is a terrible way to start the day. However, this clock could change that. You simply put a piece of frozen bacon in the alarm clock, set the alarm, and go to sleep. The clock gently wakes you up with the mouth watering smell of bacon the next morning, just like waking up on a Sunday morning to the smell of mom cooking breakfast. Who said there's no time to eat breakfast?
Toilet Lock
In 1969, a patent was issued for a really bad idea the toilet seat lock. First of all, fishing for your keys when you have to go seems very unpleasant. Then there is the possibility of losing the key altogether. What about guests? Just think that you would have to ask permission for the bathroom. Of course, there is the ultimate question: Why would you lock it in the first place?
I always wondered how people would react if I tried to approach a total stranger for help in a busy place like a street corner or in a noisy mall. I have always hurried past a stranger who tried to catch my attention in a busy place or when I am rushing around.
Yesterday, I was in a busy shopping mall buying a large piece of luggage because I just had the time to do it after many days of planning. After the purchase in one of the large shops, I picked up my phone from my pocket to call my driver waiting in the parking lot but my phone was dead.
I then requested the shop assistant who had just sold me the luggage to ring the number of my driver for me and she replied that it was the shop policy that they cannot use mobile phones while working in the shop.
I got out of the shop onto the busy street in front and approached a young mother with her two kids to make a request. As soon as I said “Excuse me, madam”, she grabbed both her kids and ran. I felt like a kidnapper.
I stood there, wondering how many times I had reacted to strangers like the young mum. I stood there in the busy street with people rushing by, looking at their faces to see if there was a sign of kindness on their faces.
I saw a man pretty shabbily dressed. He seemed to have noticed me and I just stopped him expecting him to rush past. My request escaped the lips. He immediately called the number of my driver and waited till my car came to be sure I was picked up, and he turned around before I could thank him adequately and was gone. I was surprised by his kindness and hope I will do likewise (同样地) to strangers who try to catch my attention from now on.
Next time you're planning to go out for a relaxing walk with your MP3 player, be sure to check the weather forecast first. Summer is the prime time for lightning strikes, a fact that Jason Bunch, a teen from Castle Rock, Colo, learned in a hard way. A couple of summers ago, he was mowing (割草) grass while listening to some Metallica on his iPod. Although there wasn't any rain falling on Bunch, he did hear distant thunder. Bunch was then struck by lightning, which seemed to travel through his music player, blowing out his eardrums and leaving him with burns where the device and its power lines were close to his body.
Devices such as MP3 players don't attract lightning, says Dr. Mary Ann Cooper, an emergency room physician at the University of Illinois Medical Center in Chicago. However, they may change the pathway that lightning's energy follows in the human body. Lightning that might have passed rather harmlessly over the skin may react differently to the metal of these devices and cause damage.
Rather than leaving your tunes at home, your best bet is watching out for lightning before it hits. Though people have been injured while using MP3 players in storms, Cooper says, “The devices' main task is keeping you from paying attention to thunder and the sky.” If you're caught in a storm, seek shelter.
Researchers found that walking around with a forced smile and fake happiness simply leads to people feeling unhappier. So, putting a brave face on your sadness could be harmful. The research also found that women suffered more than men when pretending to be happy.
Dr. Brent Scott, who led the study, said employers should take note because forcing workers to smile when dealing with the public can result in bad outcomes. He said, “Smiling for the sake of smiling can lead to emotional tiredness, and that's bad for the organization.” He also said the research showed customer-service workers who had “fake smiles” throughout the day didn't want to work, so their productivity dropped.
The study is one of the first of its kind to examine emotional expressions over a period of time and compare the different effects on men and women. Dr. Scott's team examined the effects of “surface acting”, or fake smiling, compared to “deep acting”, or making people smile by thinking of pleasant memories.
Dr. Scott said, “Women were harmed more by surface acting, meaning their moods worsened even more than men's. However, they were helped more by deep acting, which means their moods improved more by thinking of pleasant memories.”
According to Dr. Scott women tend to suffer more when pretending to be happy because they are expected to be more emotionally expressive than men. Therefore, forcing a smile while feeling down is more likely to go against their normal behavior and cause more harmful feelings.
Although deep acting can improve moods a little in the short term, Dr. Scott says it's not a long-term solution to feeling unhappy. There have been some suggestions that if you do this over a long period you start to feel unreal. You're trying to develop positive emotions, but at the end of the day you may not feel like yourself any more.
Long, long ago people couldn't write and they had no books. But they had stories. People learned the stories by heart and taught new ones to one another. Sometimes it was hard to remember them all.
The ancient Egyptians wrote their stories on something made from papyrus (纸沙草) plants. People in other places wanted to learn from the Egyptians to use papyrus. So, parchment (羊皮纸), made from goatskin, later took its place.
In ancient China books looked a little different. People there used ink to write on bamboo or silk. And then they invented paper. Made of trees, paper was easier and cheaper to make than papyrus or parchment. Paper-making later spread to the West, but there was a big problem with these early books. Every single one had to be copied and written by hand.
They carved (雕刻) a page of words into a piece of wood or stone. They could then print the page by spreading ink on the wood or stone and putting it against paper. But it wasn't until a German printer invented movable, metal letters that books became fast and easy to make. The letters could be used to print copy after copy, and the letters put together again and again to print different pages of words.
Once a luxury (奢侈品) only the rich could buy, they soon became a treasure everyone could enjoy.
A. It took years to finish making just one book.
B. But papyrus grew mainly in Egypt.
C. Things grew a little easier when writing was invented.
D. Finally books could be printed by the thousands.
E. The Chinese were the first to think of a way to speed things up a little.
F. Books in the West didn't change for a long time after that.
G. Its surface was smoother and better for writing on too.

As it is known to us, fewer and fewer students do sports regular, which makes them weak and easily tired.
There have many reasons for this. First of all, some of the students complain that they have too many homework, result in less time to take exercise. Beside, some of them think that it is very difficult for them to keep doing exercise, because it is very hard thing.
For lack of physical activities, many students were in poor health. I suggest that our school must take measures to encourage more students to take part in sports. For us students, no matter what busy we are, it is necessary to spare some time to do exercise.
