1 . Since people first launched rockets into space in the 1950s, we have been leaving behind all sorts of things. Some of them, like the camera, were lost by astronauts while they did work outside their spacecraft. But much of the space junk is made up of little pieces of things that were once bigger objects, until they struck each other and broke apart.
Some things we send into space fall back toward Earth and burn up in the atmosphere. But larger pieces sometimes survive the extreme heat and hit the ground or the ocean at great speeds. So there is always concern that something may fall from the sky and do some harm.
But space junk falling on roofs is not the biggest worry. Scientists are concerned about the “Kessler” problem. Imagine what happens when an empty rocket strikes another while orbiting the earth. Two big things become many smaller things. They then hit other things. The pieces get smaller and smaller until they form a cloud of junk that blocks the path of future space vehicles.
Marco Castronuovo, an Italian Space Agency researcher, says launching a satellite into space that would get very close to some of the larger pieces of space junk. The satellite would connect a small rocket to the useless object. When the rocket explodes, it pushes the junk into a lower and slower orbit, nearer the Earth. After a time, the junk burns up in the atmosphere. Mr.Castronuovo has proposed using a number of small satellites with robotic arms. One arm would catch the space junk, and another arm would connect the rocket. He imagines that each satellite could jump from one large piece of junk to another. He thinks this method could destroy about ten large objects each year.
Scientists have been concerned about space junk for many years. Right now, the costs of the cleanup have been too great. Mr.Castronuovo says his system could be put in place for a much more reasonable amount of money. So what can be done to clean up the space around our planet?

2 . The question of what children learn, and how they should learn it, is continually being debated and redebated. Nobody dares any longer to defend the old system, the parrot-fashion (way of learning by repeating what others say) of learning lessons, the grammar-with-a-whip(鞭子) system, which was good enough for our grandparents. The theories of modern psychology have stepped in to argue that we must understand the needs of our children. Children are not just small adults; they are children who must be respected as such.
Well, you may say, this is as it should be, and a good idea. But think further. What happens? “Education” becomes the responsibility not of teachers, but of psychologists. What happens then? Teachers worry too much about the psychological implications (暗示) of their lessons, and forget about the subjects themselves. If a child dislikes a lesson, the teacher feels that it is his fault, not the child’s. So teachers worry whether history is “relevant” to modern young children. And do they dare to recount stories about violent battles? Or will this make the children themselves violent? Can they tell their classes about children of different races, or will this encourage racial hatred? Why teach children to write grammatical sentences? Oral expression is better. Sums? Arithmetic? No; real-life mathematical situations are more understandable.
You see, you can go too far. Influenced by educational theorists, who have nothing better to do than write books about their ideas, teachers leave their teaching-training colleges filled with grand, psychological ideas about children and their needs. They make complicated preparations and try out their “modern methods” on the long-suffering children. Since one “modern method” rapidly replaces another, the poor kids will have well been fed up by the time they leave school. Frequently the modern methods are so complicated that they fail to be understood by the teachers, let alone the children; even more often, the relaxed discipline so necessary for the “informal” feeling the class must have, prevents all but a handful of children from learning anything.

3 . Doctors say anger can be an extremely harmful emotion, unless you learn how to deal with it. They warn that angry feeling can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.
Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm, reasonable way. Others burst with anger, losing control of themselves. But still other people control their anger. They cannot or will not express it.
For years many doctors thought that controlling one’s anger was more dangerous to a person’s health than expressing it. They said that when a person is angry, the brain lets out the same hormones that are produced during tense situations. They speed the heart rate, raise blood pressure, and narrow the blood vessels. In general, the person feels excited and ready to act.
Doctors said that controlling these feelings only makes the feelings continue. And this can lead to many medical problems. Doctors thought a person could prevent these problems by letting the anger out by expressing it freely. But recently some doctors held a different view. They said that people who express anger too often and violently did become, in fact, more and not less angry. They said this, too, can cause medical problems.
Some doctors say that both controlling and expressing anger can be dangerous. They believe that those who express anger strongly may be more likely to develop heart disease, and they believe that those who keep their anger inside may face a greater danger of high blood pressure.
Doctors say the solution is learning how to deal with anger. They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “Do not express your anger while angry. Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.”

4 . If you make a list of the top ten most challenging jobs in the world, chances are that being a teacher will not make the cut. But think about the daunting task millions of educators face each day as they try to teach a group of often unfriendly, disorderly kids into intelligent, wellrounded individuals. That surely has to be the toughest job in the world, especially taking into consideration that there is no promotion waiting for them even if they are wildly successful!
What if these allimportant individuals that we often take for granted disappear from our lives? That was what Project Ed and Participant Media’s Teach Campaign asked filmmakers of all ages to envision(想象) for their recently held contest.
Their short films were called “A World without Teachers”, whose intention was to inspire more young people to become teachers. However, the 62 amazing video submissions also serve as a reminder of how terrible things would be if we didn’t have these selfless individuals guiding us through life. What was interesting is that even the youngest contestants did not appear to take delight in the idea of not having anybody telling them what to do.
Highschool student Savannah Wakefield considered if art as we know it today would have been different without teachers. Would C. Monet have discovered his talent for impressionism?
Los Angelesbased Miles Horst,who won the 1,000dollar prize for the best adult submission, envisions a world where teachers are replaced by a “brain box” in his video. Youth category winner Marina Barham’s video describes a fact we all know but often forget. Teachers don’t just teach, they inspire—something that no electronic device, no matter how smart, can do!
So the next time you think your teacher is being “mean” for trying to channel you in the right direction, imagine a life without him/her. We have a feeling that it will not appear as rosy!

The Niagara Falls consist of three sections.The large Canadian falls—with their distinctive curved shape—are also known as the Horseshoe Falls.They are separated by Goat Island from the American Falls,which are separated from the narrow Bridal Veil Falls by a small island at their south end.Each side of the falls offers a different perspective,and it is always best to visit both sides to maximize your experience.
Views of Niagara Falls are free and accessible.Access to the riverside walks and parks offer great views.You can walk across to Goat Island on the bridge on foot.
Cave of the Winds,+1 7162781730.Daily 9 AM-7:30 PM from Spring 2016.A lift takes you 175 feet down to a walkway that leads you right to the bottom of the Bridal Veil Falls.You will definitely get a feel for the true power of the falls! This is the closest you can get to the falls on either side without actually leaping into them! Raincoats and slippers are provided,and you will definitely need them.Adults: 12;6-12 years old: 8;younger children:Free,but must be 42 inches or taller.
Maid of the Mist.A boat ride,taking you down around the bottom of the falls.Some information is given about the falls,but the real experience is looking up at the falls from below and feeling the mist coming off the falls(hence the name).Wear a raincoat to avoid getting wet.Boats leave from both the American and Canadian sides,so you may want to check the exchange rates to see which will be more costeffective when you visit! April-October.
The Niagara Gorge Discovery Center.Although it’s easy to enjoy the falls visually,the Discovery Center provides another way to appreciate the magnificence of the falls.Exhibits show the history of the entire area,including the falls,how they were originally formed,and how they’ve changed over time.
Aquarium of Niagara,701 Whirlpool St,tollfree:+1 8005004609.9AM-5PM.The aquarium at Niagara Falls: 10.
Niagara Scenic Trolley.Use this to get around the park more quickly if needed. 2 adults/ 1 children for the entire day.Hop on and off.
You can combine all these attractions with a Niagara USA Discovery pass for 35,which you can purchase at the attractions.
Must stay a night and see the night view of the Niagara Falls.It is equally beautiful.
During the winter season,a lot of repair work of the falls,tours,and surroundings takes place.Many areas,such as Terrapin Point and Luna Island,are closed due to slippery conditions.Winter brings a different kind of beauty to the falls and a visit during that time is certainly worthwhile,but if you want to experience the full range,plan to come in the warmer months.

8 . Your Genes, Your Future
How would you feel if someone gave you an envelope with a description of every one of your genes? Supposing this information could tell you what illnesses you were likely to get, or even what illness you might die of, would you open the envelope?
It's a difficult question to answer. But the fact is that scientists have already begun to discover how certain genes influence us. And in the next decade, they will learn a lot more.
We have known for a long time that many of our physical characteristics are inherited(继承). For example, our eye colour and certain diseases are decided by our genes. As long as you have a good diet, scientists can predict your height by looking at your parents' heights. And we now know that the need to wear glasses has a genetic cause. Our eating habits also appear to be decided by our genes!
With other characteristics, things are not so clear. Certainly, scientists have now shown that some traits(特性,特质) are strongly influenced by our genes. Do you prefer getting up early or late? To a great extent, it's your genes that decide. Do you enjoy dangerous sports such as car racing? There is a gene that influences how much excitement we need.
But with most psychological characteristics, scientists are learning that both our genes and our environment affect us. This is true of things such as how violent we are, and how well we get on with other people. So, even though scientists may soon be able to describe our genes in detail, it does not mean they will be able to predict our future with any real success.
Nevertheless, the fact is that scientists will be able to "read" our genes in the near future. This will create new problems. To give a few examples, insurance companies may not want to insure people whose genes predict certain illnesses. Employers may not want to employ people who have a gene for violence. One thing is already clear -- with these new developments, life is going to become even more complicated!
1. Which characteristics is mostly likely to be inherited?A.Eye color. | B.Interest. |
C.Future. | D.Ability. |
A.You may die of a certain illness described in the envelope. |
B.There will be an increased number of violent people. |
C.People may take part in dangerous sports such as car racing. |
D.Insurance companies may refuse to insure people with a gene for certain disease. |
A.Because we’re affected not only by our genes but also by our environment. |
B.Because scientists will not be able to read our genes in the near future. |
C.Because life in the future will be more complicated. |
D.Because scientists can’t describe our genes in detail. |
9 . Walt had a strong commercial sense of what would appeal to the public.Disneyland, Walt Disney World, and finally the other Disney theme parks around the world all came about because Walt Disney insisted that he could build an amusement park that was so much bigger and better than other amusement parks that it shouldn’t even be called an amusement park.
In 1940, he disclosed a plan to show Disney characters in their fantasy surroundings at a park across the street from the Disney studio in Burbank.
The idea of an amusement park grew in Walt’s mind as he traveled through the US and Europe and visited attractions of all kinds.Walt was sure that an amusement park would be successful in the United States if it offered a “good show” that families could enjoy together, was clean, and had friendly employees.
In 1948, he shared his concept with trusted friends, a modest amusement park with a central village including a town hall, a small park, railroad station, movie theater, and small stores.Outlying areas would include a carnival(联欢) area and a western village.Soon he added spaceship and submarine rides, a steamboat, and exhibit halls.
Four years later, he decided on “Disneyland” for the name and formed a company to develop the park, Disneyland, Inc.
In 1953, he got Stanford Research Institute to examine the economic future of Disneyland and to find the perfect location.
They broke ground in July, 1954, and one year later, Disneyland opened.Within 7 weeks, a million visitors had visited Disneyland, making it one of the biggest tourist attractions in the US.
Walt combined his talent and his sense of what the public would want with lots of hard work. In 1960, with a mixture of huge successes and failures, Disney had created something that was successful beyond Walt’s own dreams.

10 . A new collection of photos brings an unsuccessful Antarctic voyage back to life.
Frank Hurley's pictures would be outstanding—undoubtedly firstrate photojournalism—if they had been made last week.In fact,they were shot from 1914 through 1916, most of them after a disastrous shipwreck(海难), by a cameraman who had no reasonable expectation of survival.Many of the images were stored in an ice chest, under freezing water, in the damaged wooden ship.
The ship was the Endurance, a small, tight, Norwegianbuilt threemaster that was intended to take Sir Ernest Shackleton and a small crew of seamen and scientists, 27 men in all,to the southernmost shore of Antarctica's Weddell Sea.From that point Shackleton wanted to force a passage by dog sled (雪橇) across the continent.The journey was intended to achieve more than what Captain Robert Falcon Scott had done.Captain Scott had reached the South Pole early in 1912 but had died with his four companions on the march back.
As writer Caroline Alexander makes clear in her forceful and wellresearched story The Endurance, adventuring was even then a thoroughly commercial effort.Scott's last journey,completed as he lay in a tent dying of cold and hunger, caught the world's imagination, and a film made in his honor drew crowds.Shackleton, a onetime British merchantnavy officer who had got to within 100 miles of the South Pole in 1908, started a business before his 1914 voyage to make money from movie and still photography.Frank Hurley, a confident and gifted Australian photographer who knew the Antarctic,was hired to make the images, most of which have never before been published.
