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?___________
A.Only from left to right. |
B.Only from right to left. |
C.From both directions at the same time. |
D.From one direction at a time. |
2.We can learn from the passage that the human genome ________.
A.is as long as the River Danube |
B.can be easily placed on the head of a pin |
C.is coded with an alphabet of four letters |
D.is smart enough to read and take photos of itself |
3.It can be concluded that the passage is mainly written for ______.
A.specialists in the field |
B.general readers |
C.natural scientists |
D.readers with professional knowledge |
4.The real purpose of the author’s comparison of the genome to a book is _____.
A.to focus on the differences between the two |
B.to lay emphasis on the similarities between the two |
C.to simplify the concept of the human genome |
D.to give an exact description of the human genome |

It is hard to imagine that such a small country, the size of Indiana with the population of Alaska, tucked in the Himalaya Mountains, accessible only by two airplanes, is the “Happiest Country’’ in the world and has one of the fastest growing GDP’S in the world. This country is Bhutan, “Land of the Thunder Dragon”, which is located in South Asia and is encompassed by India, China, and Nepal.
Bhutan is the last standing Buddhist Kingdom in the World and, until recently, has preserved much of their culture since the l7th century by avoiding globalization and staying isolated from the world. Internet, television, and western dress were banned from the country up until ten years ago. Over the past ten years globalization has begun to change in Bhutan, but things remain perfectly balanced.
Bhutan is the only country in the world that has a ‘GNH’, which refers to “Gross National Happiness.’’The process of measuring GNH began when Bhutan opened up to globalization. It measures people’s quality of life, and makes sure that “material and spiritual development happen together.”Bhutan has done an amazing job of finding this balance. Bhutan has continually been ranked as the happiest country in all of Asia, and the eighth Happiest Country in the world according to Business Week. In 2007, Bhutan had the second fastest growing GDP in the world, at the same time as maintaining their environment and cultural identity.
In 2008,in Bhutan’s first democratic election,28-year-old Jigme KhesarNamgyel Wang Chuck was elected president of Bhutan. He promises to “maintain a stance (立场)of protection against the worst aspects of globalization, maintaining the ‘Gross National Happiness’.”But Jigme himself is no stranger to globalization. He attended high school at Phillips Academy and university at Wheaton College and then graduated from Oxford.
1.The underlined word “encompassed’’ in the first paragraph most probably means __________ .
A. covered B. surrounded
C. separated D. guarded
2.Why is Bhutan regarded as “the happiest country”?
A. Because it changes its policy and begins to open up.
B. Because it uses “GNH” to measure its achievement.
C. Because it stresses both material and spiritual development.
D. Because it has the second fastest growing GDP in the world.
3.What Can we infer from the last paragraph?
A. The election in Bhutan is far from satisfactory.
B. Globalization has influenced Bhutan’s religion.
C. Jigme’s educational background will cause distrust.
D. People in Bhutan will continue living a happy life.
4.Which of the following shows the structure of the passage?
A. B.
C. D.

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?
A.Because the human genome can destroy many illnesses. |
B.Because the human genome’s completion can help to get rid of many diseases. |
C.Because they wanted to be better known than others. |
D.Because the Human Genome Project can provided a lot of chances of work. |
2.According to the passage, which of the following countries is the most advanced in genetic research?
A.Japan | B.Germany |
C.The United States | D.China |
3.According to the passage, which of the following is NOT true?
A.If the genes can be found, scientists can study many new ways to cure illnesses. |
B.The United States began genetic research early in the 19th century. |
C.Many medical companies show great interest in drawing the human genome map. |
D.The scientists have made great progress in connecting some genes with the cancers. |
4.What is mainly talked about in this passage?
A.The great human genome. | B.The discovery of genes. |
C.Unlocking the genetic code. | D.Genes and scientists. |

The story of Sir Nicholas Winton is the one that you would imagine could only happen on the silver screen. Sir Nicholas Winton was a British man who went to heroic efforts, potentially putting himself at risk, during World War II. Sir Winton was responsible for ensuring the safety of 669 Jewish children by aiding their escape from countries occupied by Nazis. Finally, the Jewish children were brought to England where he worked to make sure families in his native country would help the kids by taking them into their homes.

Sir Winton kept his entire plan completely secret, even his wife had no idea about his planning until fifty years later. After the war, years passed and many people remained in the dark about Sir Winton's extraordinary achievement. Some fifty years later, his wife Greta was searching in their house and discovered a Winton's notebook which documented the names of all the children. She worked with BBC and they produced a TV episode(插曲) of their program "That's Life" that served as an honor for Sir Winton's work.
In 2003, Sir Winton was knighted by the Queen of England for his work. He also was even nominated for a Nobel Peace Prize. He also had a small planet named after him by Czech astronomers. Sir Winton died peacefully in his sleep at the old age of 106, in 2015. Leaders around the world paid tribute(悼念). Israel's ambassador to the United Kingdom, Daniel Taub, said, "He was a hero of our time, having saved 669 Jewish children from Nazis.
