Q: The secret of carrier pigeons' unbelievable ability to find their way home has been discovered by scientists: _ follow the roads just like we do. Scientists now believe the phrase "as the crow flies" no longer means the shortest most direct route between two points. They say it is likely that crows and other day birds also choose AA-suggested routes, even though it makes their journeys longer. Scientists at Oxford University spent 10 years studying homing pigeons using global positioning satellite (GPS) and got a surprising result. The birds often don't use the sun to decide their directions. Instead they fly along motorways, turn at crossing and even go around roundabouts , adding miles to their journeys. "It really has knocked our research team sideways to find that after a decade-long international study, pigeons appear to ignore their inbuilt directional instincts and follow the road system," said Prof Tim Guilford, reader in animal behavior at Oxford University's Department of Zoology. Guilford said pigeons use their own navigational system when doing long distance trips or when a bird does a journey for the first time. "But once homing pigeons have flown a journey more than once, they can fly home on a habitual route, much as we do when we are driving or walking home from work," said Guilford. "In short, it looks like it is mentally easier for a bird to fly down a road. They are just making their journey as simple as possible." What would be the best title of the passage? A) How Pigeons Find Their Ways Home? B) Why Pigeons Can Fly long Distance? C) Birds Follow Roads as We Do. D) Why Crows Fly the Shortest D stance?

Q: Inventor,physicist,surveyor,astronomer,biologist,artist... Robert Hooke was all these and more. Some say he was the greatest experimental scientist of the seventeenth century. Once he worked with renowned men of science like Christian Huygens,Antony van Leeuwenhoek,Robert Boyle,Isaac Newton and the great architect,Christopher Wren. Hooke's early education began at home,under the guidance of his father. He entered Westminster School at the age of thirteen,and from there he went to Oxford,where he came in contact with some of the best scientists in England. Hooke impressed them with his skill at designing experiments and devising instruments. In 1662,at the age of twenty-eight,he was named Curator of Experiments of the newly formed Royal Society of London. Hooke accepted the job,even though he knew that it had no money to pay him! Watching living things through the microscope was one of his favorite occupations. He devised a compound microscope for this purpose. One day while observing a cork under a microscope,he saw honeycomb-like structures. They were cells--the smallest units of life.In fact,it was Hooke who coined the term "cell" as the boxlike cells of the cork reminded him of the cells of a monastery . Perhaps because of his varied interests,Hooke often left experiments unfinished. Others took up where he left off and then claimed sole credit. This sometimes led to quarrels with colleagues. One work that he finished was his book MICROGRAPHIA,a volume that reveals the immense potential of the microscope. The book also includes,among other things,ideas on gravity and light which may have helped scientists like Newton while they were developing their own theories on these phenomena. Hooke made valuable contributions to astronomy too. A crater on the moon is named after him in appreciation of his services to this branch of science. Robert Hooke probably went to school in _ . A) 1647 B) 1634 C) 1662 D) 1640

Q: Ask just about any college student you know,and he is likely to tell you that he is a member of facebook.com.Many students say they check their e-mail.It's so popular "facelooking"has become a verb "Everywhere everyone is doing it,"college student Katie Silverman said,"It's like everyone's center of life." Facebook is an online social meeting place where students create profiles ,share personal information, and meet other members. It is password protected and targeted to high school and college students;members must have an edu.email address to join. Many students say it has changed their social lives, giving them an easy way to find and chat with classmates who share their interests."Some people might be too shy to go to talk to someone they like in one of their classes,but on facebook it's a lot easier to strike up a conversation,"said Rahul Vanjani. The website was founded by two Harward University students who wanted to meet more of their classmates.It became so popular that the website is at 2,200 colleges and at 22,000 high schools.It says that it has 6 million active users,two--thirds of whom are on it every day.Many of the facebook members said their parents had no idea they were on it ."No way.My parents certainly don't know about it," said a college senior who asked us not to use his name. To keep it popular,Facebook says it stops students posting improper information.Some students have paid the price.At Fisher College in Boston,two students were kicked out for using facebook.com to do something that is against the law.At North Carolina State University,four students were punished for posting photos about drinking. The passage is mainly about _ . A) student's idea about Facebook B) the development of Facebook C) the popularity of Facebook with students D) the rules of Facebook

Q: A growing number of college students are applying to take entry tests for medical and dental schools among increasing graduate unemployment in Korea. "I've decided to apply for the test to enter a medical college to become a doctor, changing from my original plan to prepare for a lawyer qualification exam in order to get a more stable job in the future," said a 24-year-old college graduate, Lee, who majored in business administration during his undergraduate schooling. The new medical and dental school system is getting popularity, attracting an increasing number of students every year since its appearance in 2004, as it is open to all college graduates regardless of their previous majors. The Education Development introduced the new medical and dental education system, in which college students with bachelor's degrees are allowed to study medicine or dentistry by taking the Medical Education Test (MET) and Dental Education Test (DET). Ten medical schools and six dental colleges that have used the new system have received 4,377 applications for the entrance exams. Applicants are getting younger compared with those in their 20s representing 76.9 percent of the total. The tests might be easier for students with biology and chemistry majors, but graduates from other majors are also applying for the tests. Under the existing medical and dental education system, students should take a two-year premedical course followed by a four-year medical course. Students graduating under the new medical or dental education system are given master's degrees, while those graduates who studied under the previous system have bachelor's degrees. Students in the old system may spend _ years at college to get bachelor's degrees. A) two B) four C) six D) seven
