More and more birds are flying to settle at Qinghai Lake, one of the highest inland lakes in China, thanks to the protection efforts of local governments. Covering an area of over 4,000 square kilometers, Qinghai Lake is also the country's biggest salt-water lake. Located in Northwest China's Qinghai Province, the lake is famous for the two islands at its northwest point--Cormorant Island and Egg Island. The two islands have plenty of floating grass and various schools of fish, offering rich food sources for birds. The islands have become a paradise for different kinds of groups of birds and have been called 'Bird Islands'. Each March and April, when ice and snow covering the Qinghai-Tibet Plateau starts to melt, over 20 kinds of birds fly to the Bird Islands to lay eggs. During the months, flocks of birds cover the whole sky over the islands and birds eggs can be found everywhere. Visitors can hear the singing of birds from miles away. These have become a world famous symbol of the lake. To protect this paradise for birds and support calls for ecological protection, China set up the Qinghai Lake Natural Protection Zone at the end of 1997. Meanwhile, the State has pointed out the Bird Islands and Spring Bay of the Qinghai Lake as central protection zones. Inspection officials and management employees often patrol the lake, improving local residents' knowledge of related laws and spreading knowledge about animal protection to visitors. They are making great efforts to call on people to love and protect the birds. At the same time, they have built special fences around the island area, to prevent wolves, foxes and other carnivorous animals, as well as illegal hunters from breaking up the birds' nest-building, egg-laying and breeding. As a result, more and more birds are coming to the islands for sheltering and breeding. The officials go around the lake mainly to _ A) let the farmers there know the animal protection law B) tell the farmers there some knowledge about animal protection. C) call on people to love and protect the birds D) all of the above

Kenji Croman has broken his bones,his shoulder and elbow, and nearly drowned several times.He's also had three close encounters with sharks over the years.A 10-foot wave landed directly on top of him five years ago,bending his body to the point that he actually kicked himself in the head."I literally heard every bone in my body crack."he said. Croman has been photographing ocean waves since 2008,sometimes risking his life to get that perfect shot at the surf break.Despite the risks and certain injuries that come with wave photography, the Hawaii resident,body surfer and former competitive swimmer wouldn't do anything else.The 36-year-old photographer loves the thrill of meeting breaking waves head on,shooting waves as his interest and shooting surfers to pay the bills. The process of photographing waves requires more than just swimming out to where the surf breaks and waiting,he says.The night before a photo shoot Croman checks Surfline.com,a website and the coastal camera network that provides live and predicted ocean weather information,to see what the winds,waves and tide will be like at certain times.Croman has both a primary camera and a backup for emergencies.He goes without a wetsuit and uses heavy duty underwater housing to protect his camera.There is no great way for him to protect himself.He admits there are probably protective clothes he should be wearing,but there is little he could have done to decrease the impact of the 10-foot wave that crashed on top of him. The hardest part of Croman's job is staying calm in the face of breaking waves when his initial reaction is to panic and swim away.At most.Croman will take two to three shots of a single wave."I've shot waves for so many years now that I see the wave in slow movement,"he said. How does Kenji Croman make a living? A) By taking swimming races. B) By teaching photography. C) By shooting surfers. D) By surfing waves.

Ques: My house is made out of wood, glass and stone. It is also made out of software. If you come to visit, you'll probably be surprised when you come in. Someone will give you an electronic PIN to wear. This PIN tells the house who and where you are. The house uses this information to give you what you need. When it's dark outside, the PIN turns on the lights nearest you, and then turns them off as you walk away from them. Music moves with you too. If the house knows your favorite music, it plays it. The music seems to be everywhere, but in fact other people in the house hear different music or no music. If you get a telephone call, only the nearest telephone rings. Of course, you are also able to tell the house if you want something. There is a home control console , a small machine that turns things on and off around you. The PIN and the console are new ideas, but they are in fact like many things we have today. If you want to go to a movie, you need a ticket. If I give you my car keys, you can use my car. The car works for you because you have the keys. My house works for you because you wear the PIN or hold the console. I believe that ten years from now, most new homes will have the systems that I've put in my house. The systems will probably be even bigger and better than the ones I've put in today. I like to try new ideas. I know that some of my ideas will work better than others. But I hope that one day I will stop thinking of these systems as new, and ask myself instead, "How will I live without them?" What does the passage mainly discuss? A) How to develop a new system. B) The function of the PIN. C) A home for the future. D) Easy life in the future.
Ans: C
When Albert Einstein was young, he was a quiet child who spent much of his time alone. He was slow to talk and had difficulty in learning to read. When Albert was five years old, his father gave him a compass. Albert was filled with wonder when he discovered that the compass needle always pointed in the same direction ---- the north. He asked his father and his uncle what caused the needle to move. Their answers were difficult for Albert to understand. Yet he spent a lot of time thinking about them. He said later that he felt something must be hidden behind things. Albert didn't like school. The German schools of that time were not pleasant. Students couldn't ask questions. Albert said he felt as if he were in prison.. One day Albert told his uncle Jacob how much he hated school, especially mathematics. His uncle told him to solve mathematical problems by pretending to be a policeman. "You are looking for someone," he said, "but you don't know who he is. Call him X. Find him by using your mathematical tools." Albert learned to love mathematics. He was studying the _ mathematics of calculus while all his friends were still studying simple mathematics. Instead of playing with his friends he thought about things such as "What would happen if people could travel at the speed of his light?" Albert wanted to teach mathematics and physics. He graduated with honors, but it was a pity that he could not get a teaching job. We can learn from the passage that _ . A) Einstein became a mathematics teacher after graduation B) Einstein gradually loved mathematics with his uncle's help. C) Einstein's uncle was a policeman. D) Einstein liked playing with other children.
