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.

Young people and older people do not always agree. They sometimes have different ideas about living, working and playing. But in one special program in New York State, adults and teenagers live together in a friendly way.
Each summer 200 teenagers and 50 adults live together for eight weeks as members of a special work group. Everyone works several hours each day. They do so not just to keep busy but to find meaning and fun in work. Some teenagers work in the forests or on the farms near the village. Some learn to make things like tables and chairs and to build houses. The adults teach them these skills.
There are several free hours each day. Weekends are free, too. During the free hours some of the teenagers learn photo-taking or drawing. Others sit around and talk or sing. Each teenager chooses his own way to pass his free time.
When people live together, they should have rules. In this program the teenagers and the adults make the rules together. If someone breaks a rule, the problem goes before the whole group. They talk about it and ask, “Why did it happen? What should we do about it?”
One of the teenagers has said something about it, “You have to stop thinking only about yourself. You learn how to think about the group.”

Betty and Harold have been married for years .But one thing still puzzles (困扰) old Harold .How is it that he can leave Betty and her friend Joan sitting on the sofa ,talking ,go out to a ballgame ,come back three and a half hours later ,and they’re still sitting on the sofa ? Talking ?
What in the world ,Harold wonders ,do they have to talk about ?
Betty shrugs .Talk ? We’re friends .
Researching this matter called friendship ,psychologist Lillian Rubin spent two years interviewing more than two hundred women and men .No matter what their age ,their job ,their sex ,the results were completely clear :women have more friendships than men ,and the difference in the content and the quality of those friendships is “marked and unmistakable .”
More than two –thirds of the single men Rubin interviewed could not name a best friend. Those who could were likely to name a woman .Yet three-quarters of the single women had no problem naming a best friend ,and almost always it was a woman .More married men than women named their wife/husband as a best friend ,most trusted person ,or the one they would turn to in time of emotional distress （感情危机）.“Most women ,”says Rubin ,“identified （认定） at least one ,usually more ,trusted friends to whom they could turn in a troubled moment ,and they spoke openly about the importance of these relationships in their lives .”
“In general,”writes Rubin in her new book ,“women’s friendships with each other rest on shared emotions and support ,but men’s relationships are marked by shared activities.” For the most part ,Rubin says ,interactions （交往）between men are emotionally controlled –a good fit with the social requirements of “manly behavior .”
“Even when a man is said to be a best friend ,”Rubin writes ,“the two share little about their innermost feelings .Whereas a woman’s closest female friend might be the first to tell her to leave a failing marriage ,it wasn’t unusual to hear a man say he didn’t know his friend’s marriage was in serious trouble until he appeared one night asking if he could sleep on the sofa .”
1.What old Harold cannot understand or explain is the fact that .
A.he is treated as an outsider rather than a husband
B.women have so much to share

2.Rubin’s study shows that for emotional support a married woman is more likely to turn to .
A.a male friend B.a female friend C.her parents D.her husband
3.Which of the following statements is best supported by the last paragraph ?
A.Men keep their innermost feelings to themselves.
B.Women are more serious than men about marriage.
C.Men often take sudden action to end their marriage.
D.Women depend on others in making decisions.
