Article: The Crouch quadruplets have always been considered quite special but not so special---all four have been accepted into America's Yale University. Dean at the university, Jeffrey Brenzel, said the admission for Kenny, Martina, Ray and Carol, all 18-year-old students at Danbury High School in Connecticut , was probably the first for the university. "The living memory in the office here shows that we've just had twins, never quadruplets," he told the reporters. "They are all interesting and quite smart in their own way. They are extremely lively kids, very attractive, but clearly four different people. They are all in the top 10 percent of the class." The quadruplets explained to The New York Times how they nervously logged on one by one to the Yale website to discover their fates, First was Ray, who described how the screen suddenly turned Yale blue and displayed the university's bulldog mascot with the message "welcome to the Class of 2014". "We just kept logging on and screaming, logging on and screaming,' Martina, last to find out, said in an interview with the local television station WINH-TV. Until May 1 they have to decide whether to accept Yale's offers and part of the decision will come down to money, they told the Times. Their father Steven works as a case manager with the Connecticut mental health department and their mother, Caroline, who originally came from Nigeria, is studying for her master's degree in social work, according to the Times. Ranked as one of the top three universities in the US after Harvard and Princeton, Yale's school fees each year can be as high as 36,500 dollars, which would land the Crouch family with a very heavy load by the time they graduate in 2014. Question: Why did the quadruplets keep logging on the Yale website? - They liked to see the university's bulldog mascot. - They wanted to know whether they would be in the same class. - They wanted to get some information about Yale University. - They wanted to find out if they were admitted to the university.
They wanted to find out if they were admitted to the university.

According to scientists at the Massachusetts Institute of Technology (MIT) in the US, it might be artificial leaves. Natural leaves can change sunlight and water into energy. It is known as photosynthesis . Now researchers have found a way to imitate this process. The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts . Similar to natural leaves, it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell, using those two materials to produce electricity, located either on top of a house or beside the house. Though the leaf is shaped like a poker card, scientists stated that it is promising to be an inexpensive somtoe of electricity in developing countries. "One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology," said an American scientist, Docera. An artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but too expensive and unstable for practical use. The new leaf, however, is made of cheap materials, easy to use and highly stable. In laboratory studies, Nocera showed that an artificial leaf could operate continuously for at least 45 hours. The wonderful improvements come from Nocera's recent discovery of several powerful new, inexpensive catalysts. These catalysts make the energy transformation inside the leaf more efficient with water and sunlight. Right now, the new leaf is about 10 times more effective at carrying out photosynthesis than a natural one. Besides, the device can run in whatever water is available. Hopefully, each home could possible have the access to the new application in the future. Question: Which of the following is NOT the advantage of the new leaf? - It has a wonderful fuel cell. - It is small in size. - It is low in cost. - It is convenient for people to use.
It has a wonderful fuel cell.

Read the following article and select the best answer. Article: From the earliest times,man has been interested in art.People have often worked together to collect and save the world's art treasures. Fine art treasures from many countries are kept in an art museum called the Louvre in Paris,France.The works of art have been collected by the people of France over many centuries. The Louvre has not always been a museum.The first building was a fort .In 1190,it was the king's castle with high walls and a round tower.It had a _ to keep out his enemies. Over the years,the number of buildings around the castle grew.By 1350,the castle was no longer needed as a fort.The Louvre became a palace home for French kings and queens. During times of peace,new treasures were brought in.During days of war,many treasures were stolen,and the buildings were damaged. When Francis I became king of France in 1515,he brought in artists from many countries.One of the artists was Leonardo da Vinci from Italy.Da Vinci's "Mona Lisa" is the best known painting in the museum today. In 1793,the Louvre became a public museum,just as it is now.It is a place where art treasures have been saved for everyone to enjoy. Question: On the whole,this passage is mainly about _ . - an art museum called the Louvre - an Italian artist named Leonardo da Vinci - a king of France named Francis I - the best known painting in Louvre
