    With only about 1,000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species. That's a move similar to what Texas A & M University researchers have been undertaking for the past five years in a project called "Noah's Ark".

    Noah's Ark is aimed at collecting eggs, embryos (胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M's College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.

    It is estimated that as many as 2,000 species of mammals, birds, reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.

    This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal. The entire procedure could take from three to five years to complete.

    "The nuclear transfer (核子移植) of one species to another is not easy, and the lack of available panda eggs could be a major problem," Kraemer believes. "They will probably have to do several hundred transfers to result in one pregnancy. It takes a long time and it's difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort," adds Kraemer, who is one of the leaders of the Project at Texas A & M, the first-ever attempt at cloning a dog.

    "They are trying to do something that's never been done, and this is very similar to our work in Noah's Ark. We're both trying to save animals that face extinction. I certainly appreciate their effort and there's a lot we can learn from what they are attempting to do. It's a research that is very much needed."

(1)、The aim of "Noah's Ark" project is to __________.
A、save endangered animals from dying out B、make efforts to clone the endangered pandas C、collect DNA of endangered animals to study D、transfer the nuclear of one animal to another
(2)、According to Professor Kraemer, the major problem in cloning pandas would be the lack of __________.
A、host animals B、enough money C、available panda eggs D、qualified researchers
(3)、The best title for the passage may be __________.
A、China's Success in Pandas Cloning B、The First Cloned Panda in the World C、Exploring the Possibility to Clone Pandas D、China — the Native Place of Pandas Forever
(4)、From the passage we know that __________.
A、scientists try to implant a panda's egg into a rabbit B、Kraemer and his team have succeeded in cloning a dog C、two thousand species will probably die out in over a century D、Kraemer will work with Chinese scientists in clone researches

    A long-term American study shows the importance of early education for poor children. The study is known as the Abecedarian Project. It involved more than one-hundred young children from poor families in North Carolina.

    Half of the children attended an all-day program at a high-quality child-care center. The center offered educational, health and social programs. Children took part in games and activities to increase their thinking and language skills and social and emotional development. The program also included health foods for the children.

    The children attended the program from when they were a few weeks old until the age of five years. The other group of children did not attend the child-care center. After the age of five, both groups attended public school.

    Researchers compared the two groups of children. When they were babies, both groups had similar results in tests for mental and physical skills. However, from the age of eighteen months, the children in the educational child-care program did much better in tests.

    The researchers tested the children again when they were twelve and fifteen years old. The tests found that the children who had been in the child-care center continued to have higher average test results. These children did much better on tests of reading and mathematics.

    A few years ago, organizers of the Abecedarian Project tested the students again. At the time, each student was twenty-one years old. They were tested for thinking and educational ability, employment, parenting and social skills. The researchers found that the young adults who had the early education still did better in reading and mathematics tests. They were more than two times as likely to be attending college or to have completed college. In addition, the children who received early education were older on average, when their first child was born.

    The study offers more evidence that learning during the first months and years of life is important for all later development.

    The researchers of the Abecedarian Project believe their study shows a need for lawmakers to spend money on public early education. They believe these kinds of programs could reduce the number of children who do not complete school and are unemployed.

    In addition to seeing wonderful films, one of the joys of coming to the Quad Cinema is to hang out in the area. The Quad Cinema is located right in the heart of Greenwich Village, perhaps the most charming and interesting neighborhood in the city. Here are some attractions we recommend, all within a comfortable walk from the Quad Cinema:

Washington Square Park

    As one of the best-known of New York City's 1,900 public parks, it is a landmark in the Manhattan neighborhood of Greenwich Village, as well as a meeting place and center for cultural activity. Come on a Sunday when it's most lively and festive.

New York University

    It surrounds Washington Square. See the wonderful Bobst Library and visit the amazing bookstores.  NYU is now considered one of the most powerful universities in the world.

Judson Memorial Church

    Located in the south of Washington Square between Thompson Street and Sullivan Street, opposite Washington Square Park, this beautiful church was completed in 1892. The Judson Memorial Church is most famous for its vocal participation in social events.

Washington Mews

    It is a hidden, private street in New York City between Fifth Avenue and University Place, just north of Washington Square Park. It was first developed as a mews(马厩街) that serviced horses from homes in the area. Since the 1950s the former stables have served as housing,  offices and other facilities for New York University.

Jefferson Market Courthouse

    Built in 1833 as a market, it was later changed to a courthouse, and in the 1950s it was emptied and close to being destroyed. It was saved and turned into a library. Many consider it to be the most beautiful building in the village.

    Plants are helpful to human: they provide us with wood and other products, they give us shade, and they help to prevent drought and floods.

    Sadly, in many parts of the world man has not realized that the third of these services is the most important. In his eagerness to draw quick profit from the trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he had.

    Several thousand years ago a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became hard and poor. When the empire fell to pieces, the country found itself faced by floods and starvation.

    Even if a government realizes the importance of a plentiful supply of trees, it is difficult for it to persuade the villager to see this. The villager wants wood to cook his food with, and he can earn money by making charcoal(木炭) or selling wood to the townsman. He is usually too lazy or too careless to plant and look after trees. So unless the government has a good system of control, or can educate the people, the forests will slowly disappear.

    This does not only mean that the villagers? Sons and grandsons have fewer trees. The results are even more serious. For where there are trees their roots break the soil up—allowing the rain to sink in and also hold the soil, thus preventing it being washed away easily, but where there are no trees, the soil becomes hard and poor. The rain falls on hard ground and flows away on the surface, causing floods and carrying away with it the rich topsoil, in which crops grow so well. When all the topsoil is gone, nothing remains but a worthless desert.

    Reports tell us that Americans work more and vacation less than people in other major industrial countries. Still, millions of Americans do try to get away from home for a week or two in the summer months. Some might even have the time and money to spend longer on vacation.

    For example, many retired Americans can be found driving around the United States in big recreational vehicles, known as R. V.'s. These serve as a home away from home. In fact, it might even be their only home as they see the country.

    Some American families get in their cars and drive to historic places like Colonial Williamsburg in Virginia. There, they can experience what life was like for early Americans. If that is not exciting enough, also in Williamsburg is a water park and an amusement park with rides.

    Other Americans visit national parks like Yellowstone or Yosemite out in the West. They want to spend time with nature. Or they take their vacation by a lake or the ocean. They might swim or fish. But many just want to sit and enjoy the feeling of doing nothing, except maybe read a book.

    Some families fly to other countries on vacation. Or they go on a cruise ship (大型游轮) and stop in different ports. Cruise ships are like floating cities.

    But not everyone goes someplace special on vacation. This might be the only time for people to work on things like home improvement projects. And while they do that, they might think of all the fun their friends are having.

    Last Thursday, Michael and Linda stood behind large food trucks distributing meals to 4,000 homeless people for their wedding reception on the border town of Kilis. The couple had decided that instead of hosting their friends and family for a traditional feast reception, they would feed the victims from an earthquake-stricken area.

    The idea came from the bridegroom's father, Ted, who volunteers for a Turkish relief organization. For the past few years, the organization has distributed daily meals to thousands of people who've suffered from natural disasters. He approached a representative of the organization and suggested that the family cover part of the costs of feeding them for the day.

    Then he told his son, who was surprised by the suggestion, but soon won over. When he told that to the bride, she was really shocked but finally accepted because in southeastern Turkey there is a real culture of sharing with people in need. They love to share their food, their table and everything they have. And afterwards she was quite amazed about it. So, they arrived at the distribution center on Thursday to spend the day serving food and taking photographs with their grateful recipients(接受者).

    On Tuesday evening, the newly married couple were still pleased with their decision to quit a personal celebration for one with a greater good. "It's like sharing a dinner with your friends and family who have this kind of thing on a daily basis or sharing something with people who don't even have the most basic things," Michael said. "Hopefully, this will also give the start for other wedding dinners to be held here with our brothers and sisters in need."

    Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, texting or checking updates on We Chat without looking at what was going on around them. As the number of this new “species” of human has kept rising, they have been given a new name—phubbers (低头族).

    Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones, a doctor plays with his cell phone while letting his patient die, a pretty woman takes selfe in front of a car accident site, and a father loses his child without knowing about it while using his mobile phone, a chain of similar events eventually leads to a series of destruction.

    Although the ending sounds overstated, the damage phubbing can bring is real.

    Your health is the first to bear the consequence (后果) of it. “Constantly bending your head to check your cell phone could damage your neck,” Guangming Daily quoted doctors as saying. “The neck is like a rope that breaks after long-term stretching.” Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.

    But that's not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.

    It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.
