The Human Genome(基因组) Project, a great $3 billion, 15-year task aimed at drawing the genetic map of humans, is now more than 90 percent completed. The scientific and medical communities are very excited about the chances genetic research provides for getting rid of diseases and prolonging(延长)human life. But those communities and policy makers are also careful about the scientific door they are opening as the project uncovers the mysteries of life.

For the last few years, the genetic advances in the fast developing field of biotechnology have provided material for all kinds of work, but the developments of modern science in unlocking the secrets of human genetic code have opened a world of possibilities for human health, as well as for the population imagination.

While European and Japanese researchers are making rapid progress in decoding human DNA, the leading organization for genetic research in the Untied States, which began in 1990, is “unlocking the code” of the human body to learn how to defeat fatal diseases. Already, the Human Genome Project has become widely known and praised for finding the genes connected with as yet terrible diseases, and making progress toward separating the genes that show a sign of breast cancer(乳腺癌)or AIDS.

Once these genes are found and studied, researchers can develop new ways to attack infections, and genetic diseases. Medical companies are very interested in mapping the human genome, as they expect to develop a lot of new drugs for these illnesses.

1.Why did the scientists work so hard at mapping the human genome?

2.According to the passage, which of the following countries is the most advanced in genetic research?

3.According to the passage, which of the following is NOT true?

4.What is mainly talked about in this passage?

Imagine that the genome （基因组） is a book．The book consists of 23 chapters with thousands of stories made up of paragraphs, words and letters on different levels．There are one billion words in the book, as long as 800 Bibles; if I read the genome out to you at the rate of one word per second for eight hours a day, it would take me centuries; if I wrote out the human genome, one letter per millimeter, my text would be as long as the River Danube．This is a huge volume, a book of great length, but it all fits inside an extremely small cell nuclear（细胞核） that fits easily upon the head of a pin．

The idea of the genome as a book is not, strictly speaking, even a metaphor．It is true to a great extent．A book is a piece of digital information, written in one-directional form and defined by a code that translates a small alphabet of signs into a large dictionary of meanings through the order of their groupings．So is a genome．The only difference is that all English books read from left to right, while some parts of the genome read from left to right while some from right to left, but never both at the same time．

While English books are written in words of different lengthens using twenty-six letters, genomes are written entirely in words of three-letter length, using only four letters, and instead of being written on flat pages, they are written on long chains of DNA molecules （分子）．

The genome is a very clever book, because in the right condition it can both photocopy itself and read itself．

1.How do human genomes read according to the passage?___________

2.We can learn from the passage that the human genome ________．

3.It can be concluded that the passage is mainly written for ______．

4.The real purpose of the author’s comparison of the genome to a book is _____．

The Independent Project at the Monument Mountain Regional High School in Great Barrington, Massachusetts, is attracting huge interest in the education field. The program is a new concept that has developed a wide variety of students’ abilities and excited their interest in education and self-directed learning. They are a group of students that , instead of being educated through the normal school courses, have created their own subjects and project-based interactive learning.

The students are almost completely independent. They choose a goal that they want to accomplish and work on for the whole year. These goals have included some impressive attempts such as writing a novel, writing a play , learning the piano and more. Along with these larger attempts , the students meet every day to ask questions about other subjects like natural sciences , social sciences, etc. Although most of them say that they don’t like math, they did eventually develop an interest in math through this independent learning technique.

The education program, which has attracted a huge variety of students, allows the students to learn and develop research skills and questioning techniques and allows them to truly be interested in the subjects they are diving into . They also teach each other what they have learned , which allows them to develop different way of presenting and gathering material that they have researched.

I wish that I could have participated in such a project during my high school career, like writing a novel. I am currently studying English as well as education to pursue a teaching degree. I would love to adapt independent driven projects into a classroom in the future.

This project also raises some crucial questions. Do we need to rethink the structure of the education system itself? Are too many students being simply fed through a conveyor belt(传送带) that we　 blindly see as working toward their education? I think that the education system needs some improvements , and different learning styles need to be addressed immediately.

Individual differences in learning are huge keys to the functioning of a classroom. This project takes the idea to a whole new level. This is an extremely important event in the development of the American education system and I think everyone needs to keep an eye out for more programs like this.

1.What can we learn about the Independent Project？

A. There is little involvement from teachers.

B. Normal school courses are also available.

C. The students meet every week to discuss their courses.

D. It was designed to improve the students’ interest in math.

2.By saying “Are too many students --- toward their education?” the author seems to imply that ________.

A. teachers are really important for students.

B. different learning styles should be encouraged.

C. the project works like a conveyor belt of information.

D. knowledge can be better conveyed in smaller classes

3.What is the passage mainly about ?

A. The benefits of interactive learning　　 B. Individual differences in learning.

C. A group of independent students.　　 D. An unusual education program.

Something big is happening to the human race, something that could be called the Great Transformation.

The Transformation consists of all the changes that are occurring in human life due to advancing technology. For thousands of years such progress occurred slowly. Now everything is changing so fast that you may find yourself wondering where all this progress is really leading.

Nobody knows what all these changes will really mean in the long run. But this mysterious Transformation is the biggest story of all times. It is the story of the human race itself.

Some people worry about what will happen when the deposits(蕴藏)of petroleum are gone, but already researchers are finding all kinds of new ways to get energy. Someday, solar power collected by satellites circling the earth or fission(裂变) power produced by mankind may give us all the energy we need for an expanding civilization(文明).Space exploraton promises to open up much new land for human settlement, as well as leading to the harvest of mineral resources.

Like it or not, our advancing technology has made us masters of the earth. We not only control all the other animals, but also reshape the world’s plant life and even its soil and rocks, its waters and surrounding air.

Technology gives us the power to build a great new civilizaion, if we can just agee on what we want it to be, bu today, there is little global agreement on goals and how we should achieve them.

So it remanins to be seen what will happen as a result of our technology. Pessimists (悲观主义者) worry that we will use the technology eventually to blow ourselves up. But they have been saying that for decades, and so far we have escaped. Whether we will continue to do so remains unknown, but we can continue to hope.

68.The Great Transformation is caused by ________.

A. changes in human life    B.the development of science and technology

C. space exploration        D. unknown reasons

69.Today it is impossible for people to build a remarkable new civilization because __________.  A.nobody is optimistic about the future

B.human beings aare unabale to do so

C.people diagree with each other in many ways

D.people are worried too much

70.Advancing technology could possibly make us_______.

A.hesitate    B.decisive      C.powerless      D.mysterious
