It’s 4 am, and Danilo C. Dequina is already awake. Holding a flashlight and a bucket, he is walking in the pre-dawn darkness along the shore of Old Poblacion Beach in the town of Maitum, Sarangani, in the far south of the Philippines.
A few minutes later, he spots a patch of sand that appears to have been disturbed by a turtle. Dequina studies the area carefully, figuring out where the eggs have been buried, and then starts digging slowly. After clearing away several centimeters of sand, he uncovers a large group of eggs, roughly the size of ping-pong balls. He picks them up and puts them in the bucket.
Dequina carries the eggs to his hatchery (孵卵所), some 50 meters away from the seashore. The hatchery is really just a sandy patch of land under the coconut trees enclosed by a black fence. It is here that he buries the turtle eggs he has collected. Today, Dequina scoops a hole, puts the eggs in it, and covers them with sand. After 45 to 70 days, the eggs will hatch. Dequina will then carry the hatchlings to the shore, and release them into the sea. He admits to feeling sorrow as he sets the hatchlings free -- most are hunted down by natural predators, and just one percent survive to adulthood.
According to the Philippine Department of Environment and Natural Resources (DENR), eight species of sea turtles face extinction, including four that come to the shores of Sarangani to lay their eggs -- the Hawksbill, Olive Ridley, Loggerhead and Green Turtles.
After learning about their plight (困境), Dequina attended a DENR training session on turtle conservation and decided to take action. He helped the local government to set up the Pawikan Nesting Sanctuary next to his house in 2003.
The hatchery drew the attention of the locals. “They started to change their attitudes towards sea turtles,” 52-year-old Dequina says. “If they see turtle eggs, they will either bring them to me or inform me of the nesting places.” Over the past ten years, more than 3,000 hatchlings have been released to the ocean.Dequina walks along the shore to ________.

Popeye the Sailor first became a popular cartoon in the 1930s. the sailor in that cartoon ate lots of spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.
Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.
People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.
Today, we know that the little iron in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.
It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.A good title for this reading passage is______.
| A．Popeye the Sailor |
| B．The Truth About Spinach |
| C．A Mistake with Numbers |

Facebook is now used by 30 million people in the UK, around half the population. Joanna Shields, vice president of Facebook Europe, made the announcement this morning at a media conference in London.
Globally, Facebook has more than 500 million registered （注册的） users, a milestone it hit last summer. Last July it had 26 million registered UK users. In the last eight months, it has attracted four million extra UK users, bringing the UK total to 30 million.
Facebook, the brainchild of Mark Zuckerberg while he was still studying at Harvard University, was launched in February 2004. The pace of its global growth has sped rapidly - Facebook had only 150 million registered users in January 2009.
One third of women aged between 18 to 34 check Facebook when they first wake up, before even going to the toilet, according to the research. 21% check Facebook in the middle of the night, while 42% of the same group think it is fine to post drunken photos of themselves onto the social network, a study by Oxygen Media and Lightspeed Research found.
Shields was speaking this morning at the Financial Times Digital Media and Broadcasting Conference about the power Facebook’s referrals （好友推荐）can bring to media sites, such as newspapers and TV services. She explained that the average Facebook user has 130 friends who they share links to media sites with regularly. “Media companies which take advantage of that are really seeing the benefits,” Shields said. Shields refused to be drawn on whether Facebook would develop its own mobile phone operating system and also said it was “silly” that Google had recently disabled the feature which allowed Google users to refresh their contacts with Facebook friends.Eight months ago the number of registered users of Facebook in UK was about ____.
| A．less than half of its population | B．30 million |
| C．4 million | D．500 million |
Shields talked at the Financial Times Digital Media and Broadcasting Conferences about the following EXCEPT ____.
| A．Facebook’s referrals |

Popular music in America is what every student likes. Students carry small radios with earphones and listen to music before class, after class, and at lunch. Students with cars buy large speakers and play the music loudly as they drive on the street.
Adult drivers listen to music on the car radio as they drive to work. They also listen to the news about sports, the weather, and the life of American people. Most of the radio programmers are music.
Pop or popular music singers make much money. They make a CD or tape which radio stations use in many places. Once the popular singer is heard all over the country, young people buy his or her tapes. Some of the money from these tapes goes to the singer. Wherever the singer goes, all the young people want to meet him or her. Now the singer has become a national star.
There are other kinds of music that are important to Americans. One is called folk music. It tells stories about the common life of Americans. Another is called western or country music. This is started by cowboys who would sing at night to the cows they were watching. Today, any music about country life and the love between a country boy and his girl is called western or country music.This passage mainly talks about ____.

Recently I paid a visit to Harvard University, where there are top class scientists and professors and the best academic system in the world.
I was pretty shocked when I first stepped onto the campus. Well, it’s not ever really a campus. It’s a more like district in a small town.
Harvard's main buildings are from the 18th century. They look very old and simple. You might even say they're a little shabby (破旧的). They don’t fit the modern idea of university at all. The buildings are surrounded by grass and trees, so I felt as if I had walked into a medieval castle. But when I looked across the street, busy shops and in-fashion students made me feel like I was in the 21st century again. It creates a strong contrast (对比) and brings a special atmosphere (氛围) to the school.
Our tour guide Gary took us around and told us: “You see this grass field in the center of the school? Here is where they host their graduation ceremony. They just set up tents and benches and have a very simple ceremony. Unbelievable! Who would think the most talented students just graduate on the lawn?”
I saw some students put a blanket on the grass and lie down to read a book. When I listened to the soft sound of pages turning, along with chirping of the birds, I felt very calm. There was no competitive feeling at all.
Harvard has the world’s first computer in its science center and there are hundreds of high-end computers too. Its religion and the literature departments are also among the best. It is the perfect mix of tradition and new technology. It makes Harvard a very attractive place to study in.
I hope one day I’ll attend my dream school—Harvard.According to the article the author was most impressed by ____.
| A．Harvard’s mix of tradition and new technology |
| B．the classes held on beautiful lawns at Harvard |
| C．Harvard students not taking their graduation ceremony seriously |
| D．the feeling of not living in modern society on the campus |
What can we conclude from the article?
| A．Harvard campus is actually a district of a big city. |
| B．There are no competitions at Harvard University. |
| C．Graduation ceremonies are not complex at Harvard. |
| D．All Harvard buildings date back to the 18th century. |
Which word can be used to describe the Harvard campus?
| A．Modern | B．Competitive | C．Peaceful | D．Splendid |
Chinese scientists have found a new way to use cells found in human urine （尿液）that could aid in the treatment of a range of nerve disorders.That is a new technique for reprogramming cells in human urine into nerve progenitor cells that can grow into multi-functional nerve and brain cells.
The technique is expected to be used in the study and treatment of nerve disorders such as Parkinson's disease, Alzheimer's disease and other nerve disorders.
Pei Duanqing, a professor at Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, said his research team has combined an episomal system to deliver reprogramming factors with a chemically defined culture medium to reprogram kidney epithelial(肾表皮) cells in urine into NPCs.
These NPCs, normally only found in the human brain, were later proven to be transgene-free and self-renewing, he said.
"These nerve and brain cells can survive for up to one month when transplanted into the brain of a newborn rat," said Pei. "My team is working hard to understand why our experimental condition allowed the urine cells to become NPCs, because we want to improve the technique and make it more efficient".
Scientists have long searched to treat and study neural disorders by obtaining and transplanting neural stem cells. However, the previous method of getting and using cells from either fetal (胎儿)or adult human tissue remains challenging due to ethical concerns and immune system rejections, he said.
Pei hopes the discovery will be used to generate NPCs from patients with nerve disorders such as Parkinson's disease. "These NPCs from patients may help us discover new drugs for these diseases."
"It is a remarkable advance in the stem cell field. The results and methods obtained from this study will be of great value and significance to the field, " said Fred Gage,a professor with the Salk Institute for Biological Studies.What is the passage mainly about?
| A．NPCs are beneficial in treating human diseases. |
| B．Chinese scientists succeeded in making NPCs from human urine. |
| C．Chinese scientists have found cures for all diseases. |
| D．A new technique was used to study the use of human urine |
Pei and his tean try their best to work hard in order to .
| A．make more contributions to medical study |
| B．discover another new technique |
| C．make the technique more perfect |
| D．treat more patients suffering from bad diseases |
What is the challenge of making NPCs in the previous method?
| A．The ethical comcerns and immune system refusal |
| B．The difificulties in getting cells from human. |
| C．The under-developed techniques in medical science. |
| D．The lack of financial support from the government. |
From the last paragraph we can infer .
| A．the new technique will be developed in science |
| B．the results and methods will be applied to treating cancers |
| C．the study will give a major push to the stem cell field |
