Cloning technology made its first leap from science fiction to science fact in 1997. That year, Scottish researcher lan Wilmut created the world's first animal clone：a sheep named Dolly. In making Dolly, Wilmut defied(对…挑战) nature because Dolly was produced without the union of male and female sex cells.
The method that Wilmut used to create Dolly is neither a top-secret nor hard to understand. First, he removed an egg cell from an adult female sheep. Then, he used a fine needle to suck out(吸出) the egg' s nucleus(细胞核), the structure that houses a cell' s DNA(deoxyribonucleic acid(脱氧核糖核酸). DNA contains the biological material that determines what an organism looks like and how it functions.
Next, Wilmut removed a skin cell from another sheep－the sheep he wished to copy. Placing the empty egg cell and the skin cell side by side, he forced the two cells to fuse by zapping(用辐射线照射) them with a charge(电荷) of electricity. By doing that, Wilmut created an egg from one animal that contained the DNA of another.
The new egg cell divided and developed into an embryo(胚胎). Wilmut then implanted(移植) the embryo in he womb(子宫). In time, the embryo developed into a lamb sheep－Dolly.
For years later, a whole barnyard of animal clone, including sheep, mice, cows, pigs, and goats, has, come to life in labs around the globe. Now, the race is on how to produce the first human clone although many people are strongly against it.

智趣寒假作业云南科技出版社系列答案Dear Mr Heppell,
I am Sabrina Akhtar studying in a high school and I’ve noticed that forests are disappearing (消失).
You know, forest are disappearing around the world each year. This is because of many different reasons including, farming, tourism pollution(旅游污染), etc, If we stop doing these things, there will be a good future for people of tomorrow.
Now I’m writing to ask you to help stop forests from disappearing. You can help by getting shops to stop selling paper made from trees and changing to tree-free paper (paper not made from trees). This will help forests so much . There are many , many things we can do to help forests. If you would like to know more, please visit http://www.Rainforestweb.Org/. By changing the little things, we can make a big difference.
If you would like to contact ( 联系 ) me, please see the above address or e-mail me at shazadinol @ hotmail.co.uk. Thank you for taking your time in reading this letter.
Yours sincerely
Sabrina Akhtar

The high school diploma (文凭) is losing its value quickly, as a growing number of students graduate (毕业) from school without the math and reading skills that colleges and companies require, according to a new report.
The high school graduation exams that most states (州) require students to pass before they graduate remain far too easy. Most of the exams generally test eighth-or ninth-grade level work.
Today, even high school graduates who are going to have blue-collar (蓝领) jobs need to study the math, research and writing courses. But in high school, only students who are going to college are now required to take these courses.
“If you want a good job with a good pay, it’s a high-skill job,” said Michael Cohen, a leading member of the America Diploma Project.
The project suggests that all graduates master a wide range (范围) of skills. “A high school diploma should mean something to a company and university,” said Ohio Gov. Bob Taft, who is Achieve’s co-chairman.
In Taft’s state, about 30% students who go directly to college from high school have to take remedial classes of English or math, he said. It’s easy to see that the present high-school graduating standards are not preparing students for college education.
And with high-skilled jobs increasingly headed overseas to places like India and Ireland, states need to act, he said.
To prove why math and reading skills matter, the report includes real-life examples of problems students meet in college and that workers must solve each day on the job. ?
Some states are taking actions to upgrade the high school diploma. In Texas, all high school students, starting with the 2008 graduating class, will have to take the college-prep curriculum (大学预备课程) - unless a parent agrees to an easier course load. Other states are planning similar moves.
The report includes examples of reading and math skills that high-school students should have. Project leaders say they hope parents will use those examples to judge (评定) the coursework at their kids’ high schools.
【小题1】Why is the high school diploma losing its value quickly?
| A．Because the number of high school students is growing fast. |
| B．Because high school students fail to reach the standards. |
| C．Because the graduation tests are easier than it should be. |
| D．Because difficult courses are not required in high schools. |
| A．for good learners to study quickly and better |
| B．for slower learners weak in the subject |
| C．for learners to be taught one by one |
| D．for learners to reach a higher standard |
| A．Colleges require higher math and reading skills than companies. |
| B．It is easier for companies to find high-skilled workers in India. |
| C．Math and reading skills help little for workers to solve daily problems. |
| D．Parents ask high schools to offer college-prep curriculum in Texas. |
| A．High School Diploma Means Little |
| B．Give Students More High-skill Jobs |
| C．Math and Reading Skills Really Matter |
| D．Judge Coursework at High Schools |
Who are the top students in the world, do you know? Last week the Organization for Economic Co-operation Development (经济合作与发展组织) picked the best students in the world. They are Finnish (芬兰的). The OECD gave a test to 280 000 15-year-old students from more than 40 countries and regions (地区) last year. The OECD wanted to know how well students were doing at school.
Finnish students were No. 1 in the reading test and second in maths after Hong Kong students. Those from Japan and Finland were top in science. In the problem solving, Finnish students came second to those from South Korea. The test also showed Finland had more top students than the other countries.
Finns (芬兰人) of your age have done a really good job but don't have a sense of envy. You can learn from them. Most Finnish students make good use of the Internet. Of course not for computer games, but for doing more exercises and finding out more information.
Libraries are also important. Finland spends a lot of money on them. Many students have a free card. They read for at least one or two hours a day.
What do you usually do on the Internet? How often do you go to libraries?

|
D．Japanese students were top in science. |
3.From this passage we know that_________.
