Oldest Ever Galaxy Found

  WASHINGTON(AP)-Astronomers believe they’ve found the oldest thing they’ve ever seen in the universe:It’s a galaxy(星系)far, far away from a time long, long ago.

  Hidden in a Hubble Space Telescope photo released earlier this year is a small point of light that European astronomers now calculate is a galaxy from 13.1 billion years ago.That’s a time when the universe was very young, just about 600 million years old.That would make it the earliest and most distant galaxy seen so far.

  By now the galaxy is so ancient it probably doesn’t exist in its earlier form and has already changed into bigger neighbors, said Matthew Lehnert of the Paris Observatory, lead author of the study published online Wednesday in the journal Nature.

  “We are looking at the universe when it was a 20th of its current age,” said California Institute of Technology astronomy professor Richard Ellis, who wasn’t part of the discovery team.“In human terms, we’re looking at a 4-year-old boy in the lifetime of an adult.”

  While Ellis finds the basis for the study “pretty good”, there have been other claims about the age of distant space objects that have not held up to careful examination.And some experts have questions about this one.But even the doubters praised the study as important and interesting.

  The European astronomers calculated the age after 16 hours of observations from a telescope in Chile that looked at light signatures of cooling hydrogen gas.

  Earlier this year, astronomers had made a general estimate of 600 to 800 million years after the Big Bang(宇宙大爆炸)for the most distant unclear points of light in the Hubble photograph, which was presented at an astronomy meeting back in January.

  In the new study, researchers focused on a single galaxy in their analysis of hydrogen’s light signature, further finding out the age.Garth Illingworth of the University of California, Santa Cruz, who was the scientist behind the Hubble image, said it provided confirmation for the age using a different method, something he called amazing “for such faint objects”.

  Probably you have seen photographs of the Grand Canyon(峽谷),the great valley in the desert country of Arizona.But you must go there yourself to feel its true size and beauty.The Grand Canyon is one of the greatest natural wonders of the world.

  The Colorado River formed the Grand Canyon over millions of years.Slowly, the river cut down through hard rock.At the same time, the land was rising.Today, the canyon is one and a half kilometres deep and 445 kilometres long.The oldest rocks at the bottom of the canyon are more than 1 billion years old.The width varies from about 200 metres to 29 kilometres across.The rim(邊緣)or top of the canyon is about 2,300 metres above sea level on the South Rim, and about 3,000 metres on the other side, the North Rim.As a result, there are different kinds of plants and animals on opposite sides of the canyon.The South Rim is dry desert country.The North Rim has tall forests.

  The canyon looks different at different times of day, and in different seasons and weather.At sunrise and sunset the red, gold, brown, and orange colours of the rocks are especially clear and bright.In winter, the canyon is partly covered with snow.

  The view from the South Rim of the Grand Canyon is the best, Most visitors come to the South Rim and stay in campgrounds or hotels.Every point along the canyon's edge offers a different view.

  The North Rim of the Canyon is quieter.It takes all day to drive there from the South Rim because there is only one bridge across the Colorado River.On the way, you go through Navado Indian lands, and a colourful pink desert called“The Painted Desert”.

  You can walk down into the Grand Canyon, or you can go down on the back of a mule(小型電動機車).You can also take a boat trip down the Colorado River, and camp on the beaches at night.But whether you see the Grand Canyon from the top or the bottom, it will be an experience that you will never forget.

(1)

The sea level on both sides of the Grand Canyon is ________.

[  ]

A.

the same

B.

changing with time

C.

various

D.

very low

(2)

From the passage we can know that the ________ of the canyon is different at different time.

[  ]

A.

length

B.

scene

C.

width

D.

height

(3)

If you go to visit the canyon you'd better go to ________.

[  ]

A.

the South Rim

B.

the North Rim

C.

the bottom

D.

the top of a tree

  Good morning. I'm speaking to you today from Beijing. In just two days, I've seen some of the rich history and remarkable changes that are taking place in China, home to nearly one- quarter of the world's population.

  China is the oldest civilization on Earth. In Xi'an, on Friday, I saw the old and the new China, from magnificent Terra Cotta Warriors sculpted by artisans 2,000 years before America was founded, to the beginnings of democracy in a nearby village, where residents soon will hold elections.

  I've been touched by the warm reception given to me, my family, and the members of Congress travelling with us. Tens of thousands of Chinese families have lined the streets to greet us. For all these people, China is changing. I see cell phones, beepers, new office buildings.

  China is no longer the same country it was when president Nixon first came here 26 years ago. Never before have so many Chinese had the opportunity to start businesses, lift their families out of poverty, choose where to live, work, and travel, and enjoy the fruits of their labors.

  Today in Beijing I am meeting with China' s leaders to talk about the future of our two countries and a relationship between us that is essential to a peaceful, stable, and prosperous world in the next century. We talked about the United States and China's mutual interests ---- promoting peace in Korea, where 400,000 U.S. soldiers still risk their lives to patrol the Cold Wars last frontier; preventing a nuclear arms race between India and Pakistan; restoring economic stability in Asia; stopping the spread of unclear soldiers chemical, and biological weapons and the misspread of unclear soldiers chemical, and biological weapons and the missiles to deliver them; combating international crime and drug trafficking; preserving the environment; and opening trade.

  China is important to our future, with the largest population on Earth, a permanent seat on the United Nations Security Council, an economy increasingly connected to our own. Without China, it will be difficult to face the challenges. In dealing with China, we must stay true to a course that is both principled and pragmatic.We must continue to expand our areas of cooperation, even as we deal directly with out differences. With China, we can build a safer, more prosperous future for our children, a world of unlimited possibility in the new century

  Thanks for listening.

(1)When was the Terra Cotta in Xi'an sculpted?

[  ]

A.2,000 years ago.

B.On the beginning of the last century.

C.2,000 years before America was founded.

D.Right before Clinton's visit to China.

(2)Who traveled together with Clinton in China?

[  ]

A.His family.

B.His family and some congressmen.

C.Members of congress.

D.Reporters and bodyguards.

(3)Which of the following issue was NOT discussed by President Clinton and China's leaders during his visit in Beijing?

[  ]

A.peace in KoreA.

B.Asian economy.

C.American human rights.

D.prohibition of nuclear weapons.

(4)Which of the following impressed the president most during his visit in China?

[  ]

A.Rich history and remarkable changes of China.

B.Modern communication facilities of China.

C.Democracy progress of China.

D.Economic development of China.

(5)According to the president's address, why is China important to the U. S.?

B.Because China has a permanent seat on the United Nations Security Council.

C.Because China and the U.S. have mutual interests in the economic development.

D.All of the above.

My Best Enemy

Once again, I was in a new school. So was a girl in my class named Lisa. That’s where the similarities ended.

I was tall and she was small. My thick black hair had been recently cut short into an untidy style. Her natural blonde hair flowed to her waist and looked great. I was 12 and one of the oldest in the class while she was 11 and the youngest. I was awkward and shy. She wasn’t. I couldn’t stand her, considering her my enemy. But she liked me and wanted to be friends.

One day, she invited me over and I said yes—I was too shocked to answer any other way. My family had moved six times in six years, and I had never managed to develop any friendships. But this girl who wore the latest fashions wanted me to go home with her after school.

She lived in a fun part of town that had two pizza places, an all-night bookstore, a movie theater and a park. As we walked from the school bus stop through her neighborhood, I tried to guess which house might be hers. Was it the white one with the perfect lawn or the three –story house with a front porch? I got very surprised when she led me into an old apartment building. She lived on the fourth floor in a two-room place with her mother, her stepfather, her two brothers and her sister.

When we got into the room she shared with her sister, she took out a big case of Barbies, which was my next surprise. I had never played with them. We sat on the floor, laughing as we made up crazy stories about the Barbies. We found out that we both wanted to be writers when we were older and both had wild imaginations. We had a great day that afternoon.

Lisa was loved by the whole neighborhood. The bookstore owners lent her fashion magazines; the movie theater gave her free tickets…. Soon I was included in her magic world. We slept over at each other’s houses and spent every free moment together.

Lisa, my first real friend since childhood, helped me get through the rough years of early adolescence(青春期)and taught me an amazing and very surprising thing about making friends: you worst enemy can turn out to be your best friend.

52.The writer and Lisa were similar in the way that_________.

A.they were both new students   B.they had the same hair styles

C.they were both tall   D.they were of the same age

53.One day Lisa invited the writer_________.

A.to go to the movie   B.to go to her home

C.to go to walk in a park    D.to go to a pizza place

54.In the passage the writer described Lisa as a girl who was_________

A.a(chǎn)wkward and shy            B.rich and happy

C.quiet and lonely              D.friendly and lovely

55.Which of the following did the writer learn form Lisa?

A.How to make up stories.     B.How to deal with enemies.

C.How to make friends.         D.How to live a better life.

三、閱讀理解(40分)

Maps are our oldest literature(文獻),older than books.People think a map was the first thing the human ever wrote to communicate each other.Perhaps one million years ago,with a stick in the mud of a lake bed,the earlier human drew some lines to stand for a lake,a river,a thick forest and some good hunting grounds beyond the forest.

It made so much sense that people took it for magic(魔術),they expressed the world in a picture.There was something so real about this new thing called "map" that it helped us believe we could get there.It not only strengthened belief that good hunting existed beyond the forest,but it strongly suggested that the future existed;it was a place we could go to and be there tomorrow.What a comfort.On maps all paths lead somewhere.

41.Which of the following statements is true?

A.Maps can't be used to communicate each other.

B.Maps have the same long history as books.

C.No matter how hard you study them,maps don't make any sense.

D.None of the above is true.

42.The earlier human used lines drawn in the mud to express_________.

A.the whole world                              B.real places

C.strong belief                                          D.great comfort

43.Now people regard some lines drawn by the earlier human as _________.

A.the beginning of maps           B.the chanting form of maps

C.real maps                      D.a part of maps

44.It can be concluded that _________.

A.maps are the most useful way of communicating each other

B.the first map showed somewhere far away

C.the first map showed somewhere very near

D.the first map showed all directions
