With only about 1,000 pandas left in the world, China is desperately trying to clone (克隆) the animal and save the endangered species(物種). That's a move similar to what a 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（氮）. If certain species should become extinct , Dr. Duane Kraemar, a professor in Texas A&M University 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(capable of being used) panda eggs could be a major problem，” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy(having a baby). 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.”
小題1: The aim of “Noah’s Ark” project is to ________.
A．make efforts to clone the endangered pandas
B．save endangered animals from dying out
C．collect DNA of endangered animals to study
D．transfer the nuclear of one animal to another
小題2:Ａccording to Professor Kraemer , the major problem in cloning pandas would be the lack of _______.
A．available panda eggsB．host animals
C．qualified researchersD．enough money
小題3:The best title for the passage may be ______.

The curriculum(課程)at King’s is based on strong academic roots. It emphasizes and relies upon what is best in traditional independent school education: scholarly excellence supported by a caring and tutorial system, and a wide-ranging co-curricular programme. However, it is continually adapting and reacting to the changing demands of modern education: new subjects are added, new teaching techniques adopted, and there is an increasing awareness of the need to provide programmes of study that match individual needs and skills.
The curriculum is divided into three units: the Lower School (Year 9), an introductory year; the Middle School (Years 10 and 11), working to GCSEs; and the Sixth Form ( Years 12 and 13), taking AS and A levels.  
Full details can be found in:  Shell Guide and Handbook; Middle School Academic Guide 2009-11; Middle School Academic Guide 2010-12;  Sixth Form Guide 2009-11 and Sixth Form Guide 2010-12.
Formal and structured educational support, for those who need it, is available at all levels. The well-stocked Library is open 7 days and 6 evenings per week. ICT facilities (including the Internet) are available for all and the whole school (studies within the Houses as well as classrooms) is extensively networked.   
Pupils are offered extensive careers advice throughout their time at King’s. Almost all go to university, either immediately or following a GAP year.  The most popular university destinations are Cambridge, Bristol, Nottingham, Durham, Leeds, Oxford, Edinburgh, Manchester, and University College, London.

There are several ways to break the technology code that teenagers have written among themselves. The following are ideas to help parents understand the sometimes confusing world of the teens.
Social Networking (人際關系網) Sites: Sites like MySpace and Facebook appeal to all generations and are a good way for a parent to understand what social standards your teen is living with. There are many ways to help you take part in your child's online activities. You also can be from an onlooker (旁觀者) who keeps a bird' s-eye view of his cyber world to an active member of his social group.
MMORPG: Massively Multiplayer Online Role-Playing Game comes in the form of games. A child can easily become addicted to (沉溺于) them if no limits are set. To fully understand the attraction behind MMORPG, you can make your own account and character to explore the digital (數碼的) world. Playing the online games may seem strange at first to your teen, but experience has led me to only positive feedback (反應) from young people who can communicate with adults about their gaming experiences.
Text and Instant Messenger: The ways of teenage communication have produced a whole new language, such as "LOLZ" (laughing out loud) and "PSOS" (parent standing over shoulder). Learning the basic shorthand (速記法) of teens can open up a whole new world of communication, not only talking to your teens, but being able to listen on their terms as well. You may just find yourself texting faster and ending your correspondence (聯系) with TTYL (talk to you later). To teens, texting anyone looks cool, even Mom and Dad.
Email: Emailing your child is easy. This, of course, cannot take the place of face-to-face communication, but it provides another way for your child to reach you. Another benefit is that your child cannot act like he didn't hear you.
小題1:What does the underlined part "appeal to" in the second paragraph mean?
A．harmB．attractC．upsetD．attack
小題2:According to this passage we can infer that the author's child __________.

　　　　　　　　　　�。�
Researchers who helped discover a new species of Mexican butterfly are offering to sell the naming rights to raise money to fund more research. Co-discoverer Andrew Warren is hoping to raise at least $50,000 by auctioning(拍賣) off the rights to name the 4-inch “owl eye” butterfly, which lives in Sonora, a Mexican state bordering Arizona.
“That would support at least two years of research for our team down in Mexico,” Warren said. “Money goes a long way down here in Mexico.”
According to the scientific tradition, discoverers of a new species have the say in naming it. In recent years, some discoverers have auctioned off their naming rights to raise money.
Warren said the amount being sought for the butterfly is not out of the question, noting that naming rights for a new monkey species brought in $650,000 two years ago. A group of 10 new fish species that went on the naming auction block at the same time earlier this year brought in a total of $2 million.
The butterfly discovered by Warren and researcher George Austin ranges as far north as Mexico.
The butterfly was actually in a collection, misidentified as an example of another new species, at the McGuire Center for Lepidoptera and Biodiversity at the Florida Museum of National History in Gainesville, said Warren. They soon began the hard process of determining that it was indeed a “new” model of butterfly.
After checking photos and comparing it with other known species, they determined it was a separate species.
小題1:Where did the researchers discover the new species of butterflies?
A．In Sonora.B．In Mexico state.
C．In a place in US.D．Near the US-Mexico border.
小題2: Why will the researchers sell the naming rights of the butterfly?
A．To raise money for wildlife protection.
B．To raise money for more research.
C．To cause people’s attention to the new discovery.
D．To cover the cost of the research.
小題3:When the butterfly was first discovered, people thought ______.
A．it was a new species at once
B．it wasn’t a species of American butterfly
C．it belonged to the monarch branches
D．it belonged to a new species
小題4: We can infer from the passage that ______.
A．the new species of butterfly live both in the US and Mexico
B．it took the researchers a lot of efforts to determine the new species of butterfly
C．the researchers are not sure whether they can get the money they want from the auction
D．it is the first time that the new species of butterfly has been found

The temperature of the sun is over 5000 degrees Fahrenheit at the surface, but it rises to perhaps more than 16 million degrees at the center．The sun is so much hotter than die earth that matter can exist only as a gas, except at the core．In the core of the sun, the pressures are so great against the gases that, despite the high temperature, there may be a small solid core．However, no one really knows, since the center of the sun can never be directly observed．
Solar astronomers do know that the sun is divided into five layers or zones．Starting at the outside and going down into the sun, the zones are the corona, chromosphere, photosphere, convection zone and finally the core．The first three zones are regarded as the sun's atmosphere．
But since the sun has no solid surface, it is hard to tell where the atmosphere ends and the main
body of the sun begins．
The sun's outermost layer begins about 10000 miles above the visible surface and goes outward for mllions of miles．This is the only part of the sun that can be seen during an eclipse（日食） such as the one in February 1979．At any other time, the corona can be seen only when special instruments are used on cameras and telescopes to shut out the glare of the sun's rays．
The corona is a brilliant, pearly white, filmy light, about as bright as the full moon．Its beautiful rays are a sensational sight during an eclipse．The corona's rays flash out in a brilliant fan that has wispy spikelike（一束束穗狀） rays near the sun's north and south poles．The corona is thickest at the sun's equator．
The corona rays are made up of gases streaming outward at tremendous speeds sad reaching a temperature of more than 2 million degrees Fahrenheit．The rays of gas thin out as they reach the space around the planets．By the time the sun's corona rays reach the Earth, they are weak and invisible．
小題1:Matter on the aim can exist only in fee form of gas because of the sun's ___．
A．sizeB．ageC．locationD．temperature
小題2:All of the following are parts of the sun's atmosphere EXCEPT the ___．
A．coronaB．chromosphereC．photosphere D．core
小題3:According to the passage, as the corona ra5,'s reach -die plaasts, they become ___．
A．hotterB．clearer C．thinnerD．stronger
