Humans have always been curious about what Earth was like thousands of years ago. To learn more about the plants and animals that lived during that time, scientists examine their fossils or other remains. In recent years, genetics, and in particular the the study of DNA, has become an important tool for these scientists. Some people even dream of bringing ancient creatures such as dinosaurs back to life. Although no animals have been brought back yet, scientists have managed to grow a number of ancient plants from seeds. By far theoldest of these plants is a 32,000-year-old plant that has been grown again by Russian scientists.

The plant is a flower called Silenestenophylla, which used to grow in Siberia in eastern Russia. The scientists discovered seeds and fruits of the plant buried deep below the ground. They believe the seeds and fruits were put there by an ancient animal which stored them to eat during the winter. The seeds that scientists found failed to grow because they were damaged. However, the scientists were able to take genetic material from the fruit to grow a new plant. Then, this plant produced new seeds which the scientists were able to use to grow more plants.

A modern relative of the original flower still grows in Siberia, but when the ancient flower was grown, it had some important differences from the modern flower. The petals on the ancient flower were much longer and also spaced further apart. Studying the ancient flower will allow the scientists to learn more about how plants have evolved.

Before this, the oldest seed to have been grown was from a 2,000-year-year-old tree in Israel. The Russian scientists believe the reason why the Siberian seeds were preserved for so long is that they were buried in permanently frozen earth, which protected the genetic information in the seeds. The scientists believe that the permanently frozen soil in Siberia contains many other ancient seeds, so they may be able to bring back even older plants. This will help them better understand the history of plants and how they have changed over time.

1.Recently, scientist have ________.

A.been able to bring a number of ancient animals back to life

B.begun using genetics to learn more about ancient plants and animals

C.started to create a dinosaur that could live on Earth today

D.tried to create new types of fossils to study how animals used to live

2.How were Russian scientists able to grow Silenestenophylla?

A.They used genetic material from an ancient fruit they discovered.

B.They used ancient seeds that they had found deep below the ground.

C.They planted the seeds deep in the ground to protect them during the cold winter.

D.They planted fruit in a new kind of container that they had specially designed.

3.What is one thing the Russian scientists learned by comparing the ancient plant with its modern relative?

A.The plant used to produce fewer flowers than it produces now.

B.The plant has evolved to have shorter petals on its flowers.

C.The ancient plant was a different color from its modern relative.

D.The modern plant is found across a wider area of Russia than the ancient one.

4.The Russian scientists believe that ________.

A.it is unlikely that they can grow plants from seeds that are over 2,000 years old

B.ancient seeds that were kept in Israel will be easier to grow than Russian seeds

C.they will be able to grow plants in areas where the earth is permanently frozen

D.the frozen soil in Siberia is able to keep the DNA of plants safe for a long time

5.Which of the following statements is true?

A.Russian scientists would like to use frozen earth to protect seeds.

B.Human DNA can be used to help scientists learn more about the genetic history of plants.

C.The fruit and seeds of Silenestenophylla may have been buried by an ancient animal.

D.The first plant that had flowers grew in Siberia over 32,000 years ago.

Scientists investigated why Ebola virus is so deadly when it spreads from animals to humans and then from human-to-human contact. The research team looked at the Zaire Ebola virus in an animal system to understand how it gains strength. This virus is responsible for the current outbreak in West Africa. They found that initially the animal systems were not affected by the virus, but succeeding transmission(传送) into other animals caused the virus to “hot up” and become more severe.

The team analyzed the viruses at different stages and were able to identify several changes in its genetic material that were associated with increased disease.

Professor Julian Hiscox, who led the study from the University’s Institute of Infection and Global Health, explains: “The work tells us that the evolutionary goal of Ebola virus is to become more fatal.”

“We were able to show through genetic analysis which parts of the virus are involved in this process. The information we have gathered will now allow us to monitor for such changes in an outbreak as well as develop future treatment strategies.”

Professor Roger Hewson, leading the study from Public Health England, Porton Down, said: “Ebola virus is such a destructive infection to the people affected by the disease and the economy of West Africa.”

“Our understanding of Ebola virus biology is way behind that of other viruses and our cooperation shows how we can bring together our specialists’ skills to close this knowledge gap.”

Professor Miles Carroll, a co-author of the work, said: “This study has allowed the team to be at the forefront of developing methodologies to analyze patient samples recently taken by the European Mobile Laboratory from West Africa to understand disease evolution during the current outbreak.”

1.What does the first paragraph mainly tell us?

A. How severe Ebola virus is.

B. How Ebola virus spreads.

C. How Ebola virus gradually becomes deadly.

D. What contributions scientists have made on Ebola virus.

2.Which of the following statements is mentioned in the passage?

A. In the first stage, the virus hurts its victims much.

B. As the virus spreads, it’ll change and become more and more deadly.

C. The research in Ebola virus is more advanced than that in other viruses.

D. The scientists have a negative attitude to the research in Ebola virus.

3.The underlined word “fatal” has the closest meaning to ______.

A. optimistic　　 B. deadly

C. common　　 D. fantastic

4.Where can we probably read this passage?

A. In a science report.　　 B. In a storybook.

C. In an advertisement.　　 D. In a textbook.
