June 26, 2000 — the Human Genome(基因組) Project, a great $3 billion, 15-year task aimed at drawing the genetic(遺傳的) map of humans, is now more than 90 percent completed. The scientific and medical communities(團(tuán)體) are very excited about the chances genetic research provides for getting rid of diseases and prolonging(延長) human life. But those communities and policy(政策) makers also are 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 developing field of biotechnology(生物技術(shù)) have provides material for all kinds of work, but the developments of modern science in unlocking the secrets of the human genetic code(密碼) have opened a world of possibilities for human health, as well as for the popular imagination.
While European and Japanese researchers are making rapid progress in decoding(解碼) human DNA, the leading organization for genetic research is in the United States, which began in 1990, is “unlocking the code” of the human body to learn how to defeat fatal(致命的)diseases. Already, the Human Genome Project has become widely known and praised for finding the genes(基因) connected with terrible diseases as yet(迄今), and making progress toward separating the genes that show a sign of breast cancer or AIDS.
Once these genes are found and studied, researchers can develop new ways to attack infections(傳染), 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 hard at mapping the human genome?
A. Because the human genome can destroy many illnesses.
B. Because the human genome's completion can help them get rid of many diseases.
C. Because they wanted to be better known than others.
D. Because the human genome can provide a lot of chances of work.
2. Which country studied the genes most rapidly in the world?
A. Japan. B. Germany. C. The United States. D. China.
3. 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 scientists have made great progress in connecting the genes with the cancers.
C. Many medical companies show great interest in drawing the human genome map.
D. The United States began the Genes Study early in the 19th century.
4. The author suggests that the Human Genome Project can cause _______.
A. the policy makers to feel very worried and careful
B. the scientists to work harder
C. many people to find work easily
D. a lot of companies to produce many new drugs
5. The main idea of this article is about _______.
A. unlocking genetic code
B. the genes' discovery
C. the great human genome
D. the genes and the scientists

A recent study of ancient and modern elephants has come up with the unexpected conclusion that the African elephant is divided into two distinct (不同的) species
The discovery was made by researchers at York and Harvard universities when they were examining the genetic relationship between the ancient woolly mammoth and mastodon to modern elephants—the Asian elephant, African forest elephant and African savanna elephant
Once they obtained DNA sequences (序列) from two fossils (化石)，mammoths and mastodons， the team compared them with DNA from modern elephants. They found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian elephants and mammoths.
The scientists used detailed genetic analysis to prove that the African savanna elephants and the African forest elephants have been distinct spec
ies for several million years. The divergence of the two species took place around the time of the divergence of Asian elephants and woolly mammoths. This result amazed all the scientists.
There has long been debate in the scientific community that the two might be separate species but this is the most convincing scientific evidence so far that they are indeed different species.
Previously, many naturalists believed that African savanna elephants and African forest elephants were two populations of the same species despite the elephants’ significant size differences. The savanna elephant has an average shoulder height of 3.5metres while the forest elephant has an average shoulder height of 2.5metres. The savanna elephant weighs between six and seven tons, roughly double the weight of the forest elephant. But the fact that they look so different does not necessarily mean they are different species. However, the proof lay in the analysis of the DNA.
Alfred Roca, assistant professor in the department of Animal Sciences at the University of Minois, said, “We now have to treat the forest and savanna elephants as two different units for conservation purpose. Since 1950 all African elephants have been conserved as one species. Now that we know the forest and savanna elephants are two very distinct animals, the forest elephant should become a bigger priority (優(yōu)先)for conservation purpose .”
【小題1】One of the fossils studied by the researchers is that of ________.
| A．the Asian elephant | B．the forest elephant |
| C．the savanna elephant | D．the mastodon elephant |
| A．evolution | B．exhibition | C．separation | D．examination |
| A．DNA | B．height | C．weight | D．population |
| A．The conservation of African elephants. |
| B．The purpose of studying African elephants |
| C．The way to divide African elephants into two units |
| D．The reason for the distinction of African elephants |
| A．Naturalist’s Belief about Elephants. |
| B．Amazing Experiment about Elephants |
| C．An Unexpected Finding about Elephants |
| D．A Long scientific Debate about Elephants |

CANBERRA(Reuters)—Australia’s kangaroos are genetically similar to humans and may have first evolved in China, Australian researchers said Tuesday.
Scientists said they had for the first time mapped the genetic code of the Australian marsupials(有袋類)and found much of it was similar to the genome for humans, the government backed Center of Excellence for Kangaroo Genomics said.
“There are a few differences, we have a few more of this, a few less of that, but they are the same genes and a lot of them are in the same order,”center Director Jenny Graves told reporters in Melbourne.
“We thought they’d be completely scrambled, but they’re not. There is great chunks of the human genome which is sitting right there in the kangaroo genome,” Graves said, according to AAP.
Humans and knagaroos last shared an ancestor at least 150 million years ago, the researchers found, while mice and humans separated and went in different ways from one another only 70 million years ago.
Kangaroos first evolved in China, but migrated across the America to Australia and Antarctica, they said.
“Kangaroos are hugely informative about what we were like 150 million years ago,” Graves said.
68.Where does the kangaroo first develop according the scientists?
A.In China. B.In America. C.In Australia. D.In Antarctica.
69.What does the passage mainly tell us?
A.How the Kangaroo first evolved. B.Kangaroo’ genetic code have been mapped.
C.Kangaroos’genes are close to humans’. D.Scientists did much research into Kangaroos.
70.What does the underlined word “scrambled” probably mean in the fourth paragraph?
A.Funny. B.Wrong. C.Curious. D.Right.
