Most of us have now heard about the plane crash of German wings Flight 9525. After taking off from Barcelona, Spain, the plane crashed into the French mountains on its way to Düsseldorf, Germany. Immediately, it caused shock and also questions. How do we find out what happened?

There is one piece of equipment that is the key to discovering the mysteries of a crash: the black box. On an airplane, there are actually two black boxes: the flight data recorder (FDR) and the cockpit (驾驶员座舱) voice recorder (CVR). FDR holds altitude levels information while CVR keeps conversations in the cockpit and radio conversations with air traffic control.

Australia was the first country to require airplanes to have flight recorders—it wasn’t until 1976. Since then almost every country on Earth follows this rule.

So what did the black boxes uncover about the Germanwings Flight 9525? By using their data, it is believe that the crash was caused by the co-pilot on purpose.

In the event of a tragedy, the truth must become clear. This is why black boxes play such as important role in uncovering the truth.

3.What does the underlined word “uncover” mean in English?

4.According to the investigation, what was probably the cause of the crash of the Germanwings plane?

MOST of you may have heard about the Nobel Prize. But do you know the Ig Nobel Prize (搞笑诺贝尔奖)?The awards are given each year to 10 unusual achievements in science. It is to “honor achievements that first make people laugh, and then make them think.

This September the 2014 winners of the Ig Nobel awards came out! Research into why bananas are slippery(滑的) won the Ig Nobel for physics.

A team of scientists from Japan, tested 12 different banana skins. They then used sensors to measure the friction(摩擦力) between the slippery side of banana skin and the ground. They found that when someone steps on a banana skin, a special chemical, polysaccharide follicular gel(囊泡多糖凝胶), is set off. This chemical reduces friction by one-fifth. Later, scientists also compared banana skin with apple skin and orange skin and showed why apple and orange skins are not quite so dangerous. Friction was about 60 per cent higher on an apple peel.

Polysaccharide follicular gel is also found in the membranes (薄膜) where our bones meet. “This idea will help to design a joint prosthesis (人工关节),” Kiyoshi Mabuchi, the lead scientist, told the BBC news.

The Ig Nobel Prize in Medicine went to doctors from the Detroit Medical Center, US. They used salt pork to stop a young child’s nose bleed. Other interesting research includes whether owning a cat was bad for your mental health and looking at ugly art can be painful.

While Ig Nobel Prizes are mostly funny, great scientific breakthroughs(突破) can be made. In 2006, a team found that a type of mosquito(蚊子) is equally attracted to the smell of feet and cheese. As a result, mosquito traps were made using cheese to fight against malaria in Africa.

1.Ig Nobel Prize awards are mainly given for achievements in _____.

A. chemistry　　　 　　　　 B. Science

C. medical research　　 D. Arts

2.Which of the following is True about the banana skin research?

A. The test led to the invention of a joint prosthesis.

B. Stepping on apple and orange skins are not dangerous.

C. The test showed that apple skin is more slippery than banana skin.

D. The chemical inside the skin mainly causes the banana’s slipperiness.

3.Which research has won 2014 Ig Nobel for Medicine?

A. Looking at ugly art can be painful.

B. Salt pork can be used to treat nosebleeds.

C. Mosquitoes like the smell of feet and cheese.

D. The influence cats have on their owner’s mental health.

4.What’s the best title for this passage?

You may have heard of the old story about the world's most whole-hearted fisherman. He had out-fished his friend all morning long. They used the same live bait (鱼饵), the same equipment and fished together in the same mountain stream. But he had almost caught a bucket of fish while his friend had yet to catch even one.

"What's your secret?" asked the friend. "I haven't even gotten any one!"

The successful fisherman emptied the bait of his mouth into a cupped hand and replied. "You have to keep your worms (鱼虫) warm."

Whether or not we fish or even eat fish, there is a lesson to be learned here. We are most likely to succeed when we fully put our hearts into a task. Especially if the task before us is difficult or there seems little probability of success. Whether we want to build a new business or write that first novel, we should see how willing we are to do what it takes-even if it means keeping the worms warm.

So I often ask myself. "How much do I want this?" when some people fish, if they don't catch, they don't eat. Some things are too important for me to risk failure. So how much do I want to succeed at this career (事业) or this dream? And how hard am I willing to work? If "success" only comes before "work" in the dictionary, I may have to work harder than I've ever worked before. But if I want it enough, the hard work will be worth it.

"Always bear in mind," said Abraham Lincoln, "that your own resolution to succeed is more important than any other one thing."

And that is where it always begins: with a whole-hearted resolution to succeed—in a task, in a career, in a life. How much do you want this? And, how hard are you willing to work? Start there, and great things can happen.

1.Paragraph 1 is mainly about the old story of ________.

A.two friends B.Abraham Lincoln C.some baits D.a fisherman

2.The lesson we learned is to ________ from Paragraphs 2-4.

A.only keep the worms warm B.write the first novel soon

C.put our hearts into any task D.be willing to do nothing

3.Why does the writer often ask himself the two questions?

A.See if he has been whole-hearted. B.Be able to risk failure anytime.

C.Find out if the hard work is worth it. D.Work less harder than before.

4.What does the word "it" in Paragraph 5 refer to?

A.Career. B.Dream. C.Success. D.Work.

5.What does the writer want to tell us according to the last two paragraphs?

A.Own your resolution is the most important.

B.Do as Abraham Lincoln says, you'll succeed.

C.To succeed begins with a whole-hearted resolution.

D.Start anywhere, and great things can always happen.

Answer the questions（根据短文内容回答下列问题）

Most of us have never thought about building an educational toy by ourselves. If we need a learning toy or something, we simply go to the nearest store and buy it. However, things are not as easy in third world countries. With families even having no food to put on the table, buying toys, especially the educational ones, is the last thing on the parents’ minds.

So how can one get these kids interested in science? This was a question that worried the Indian engineer. Arvind Gupta so much that he decided to give up a good job and spend his life making toys from trash, things that people no longer want or need! Mr Gupta began teaching in the 1970s. While still an engineering student at the Indian College of Technology, he volunteered to teach the children who could not afford to go to school. Upon graduation, he found a good job at India’s Tata Motors and spent the next five years designing cars.

But he soon realized that this was not something he wanted to do for the rest of his life. So he took a year’s training course and took part in the Hoshangabad Science Teaching Program whose aim was to make science fun and exciting for poor children using available materials.

Mr Gupta found the whole project so satisfying that he decided to leave his high paying job and focus his attention on designing educational toys that were not only cheap and easy to build, but also full of scientific principles（原理）, so that children could get interested in this interesting subject.

When the Internet started becoming a more widespread learning tool, Mr Gupta created a toys from Trash website and also recorded over 250 YouTube videos.

Today, over 50,000 children and teachers visit the website daily to download the videos for the toy creations based on cool science. Some young children have become so inspired（鼓舞） that they have even won international science competitions with the help of his creations.

1.What are these educational toys made from?

___________________________________________________________

2.Did Arvind Gupta start building educational toys as soon as he graduated from the college?

3.Who did Mr Gupta build these educational toys for?
