With only about 1,000 pandas left in the world, China is desperately trying to clone the animal and save these in a dangerous situation. That's a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called "Noah's Ark".
Noah's Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of these animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M's College of Veterinary, Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2, 000 species of mammals, birds and reptiles will probably become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
"The nuclear transfer of one species to another is not easy, and the lack of available panda eggs could be a major problem," Kraemer believes. "They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it's difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort," adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog.
"They are trying to do something that's never been done, and this is very similar to our work in Noah's Ark. We're both trying to save animals that face extinction. I certainly appreciate their effort and there's a lot we can learn from what they are attempting to do. The cooperation between us is very much needed."

Death Valley is one of the most famous deserts in the United States, covering a wide area with its alkali sand. Almost 20 percent of this area is well below sea level, and Badwater, a salt water pool, is about 280 feet below sea level and the lowest point in the United States.
Long ago the Panamint Indians called this place "Tomesha"-- the land of fire. Death Valley's present name dates back to 1849, when a group of miners coming across from Nevada became lost in its unpleasantness and hugeness and their adventure turned out to be a sad story. Today Death Valley has been declared a National Monument and is crossed by several well-marked roads where good services can be found easily. Luckily the change created by human settlement has hardly ruined the special beauty of this place.
Here nature created a lot of surprising, almost like the sights on the moon, ever-changing as the frequent wind moves the sand about, showing the most unusual colors. One of the most astonishing and colorful parts of Death Valley is the Devil's Golf Course, where it seems hard for one to tell reality from dreams. Sand sculptures stand on a frightening ground, as evening shadows move and lengthen.

阅读下面短文，从每题所给的四个选项A、B、C和D中，选出最佳选项。
"BANG!" the door caused a reverberation(回声). It was just standing there, with Father standing on one side, and I on the other side.
We were both in great anger. "Never set foot in this house again!" stormed Father. With tears welling up in my eyes, I rushed out of the flat and ran along the street.
The street lights were shining rather desolately(凄凉的). I wandered aimlessly.
A young father who held a child in his arms walked past me. I felt as if I saw my childhood from another space: happy and harmonious.
But now... I don't know whether it is because I have grown up or because dad is getting old. We differ in our ways of thinking. He always forces his opinions and codes of behavior on me. Whenever I do something wrong, he never turns a blind eye to it. We are just like two people coming from two different worlds. It feels like there is an iron door between us that can never be opened.
I wandered the streets, without a destination in mind. My heart was frozen on this hot summer night. As I walked on there were fewer and fewer people on the streets, until I had only the street lights to keep me company. When I finally reached the high-rise apartment block in which I lived, I saw that the light was still on.
In fact, it was nothing. Perhaps, dad was throwing away some of his old stamps. Perhaps he thought they were useless. I never had the courage to tell him that I liked collecting stamps. I can't stand his outrageous(蛮横的) words: " I can throw you away, let alone these old papers."
All the lights were off except father's.
Dad was always like this. Maybe he didn't know how to express himself. After shouting at me, he never showed any mercy or any moments of regret. After an argument he has the habit of approaching in my sleep and then covering me with the quilt.
This was how he always was. He has been a leader for so long that telling everyone else what to do has become his second nature.
The light was still on. "Am I wrong?" I whispered, maybe... With the key in hand, I was as nervous as I had ever been. At last, I decided to open the door. As soon as I opened the door, tears ran down my cheeks. I suddenly realized that the iron door that I had imagined between us did not exist at all. Love-is second to none.
1. Decide which is the best order of the following according to what happened in the passage.
a. I opened the door and entered the house.
b. Sadly I ran out into the street.
c. I reached the place where I lived and saw my house still brightly lit.
d. I thought of my father's kindness towards me.
e. I walked about in the street without any aim.
A. b, e, d, c, a B. b, e, c, d, a C. b, e, a, c, d D. b, e, c, a, d
2. What made the writer think of his childhood?
A. The sight of the desolate street lights.
B. The sight of the empty street.
C. The sight of a father with a child in his arms.
D. The sight of light in his own house.
3. Why do you think the father often shouts at his son?
A. Perhaps the father is getting older and older.
B. Perhaps the son has already grown up.
C. Perhaps they never agree with each other.
D. Perhaps the father has got used to doing that.
4. What conclusion can you draw after reading the passage?
A. The father is actually kind to his son.
B. The father treats his son in an unfair way.
C. The father is neither kind nor cruel to his son.
D. The father is always finding fault with his son.

The African elephant,the largest land animal remaining on earth ,is of great importance to African ecosystem(生态系统).Unlike other animals,the African elephant is to a great degree the builder of its environment.As a big plant-eater,it largely shapes the forest-and-savanna(大草原)surroundings in which it lives,therefore setting the terms of existence for millions of other animals that live in its habitat(栖息地).
It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat.In its continuous search for the 300 pounds of plants it must have every day,it kills small trees and underbushes,and pulls branches off big trees.This results in many open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas.In these open spaces are many plants in various stages of growth that attract a variety of other plant-eaters.
Take the rain forests for example.In their natural state,the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor.By pulling down trees and eating plants,elephants make open spaces,allowing new plants to grow on the forest floor.In such situations,the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species.If the elephant disappears,scientists say,many other animals will also disappear from large areas of forest and savanna,greatly changing and worsening the whole ecosystem.
What is the passage mainly about?

A．Disappearance of African elephants.

B．Forests and savannas as habitats for African elephants.

C．The effect of African elephants' search for food.

D．The eating habit of African elephants.

What does the underlined phrase “setting the terms” most probably mean?

A．Fixing the time.	B．Worsening the state.
C．Improving the quality.	D．Deciding the conditions.

What do we know about the open spaces in the passage?

A．They result from the destruction of rain forests.

B．They provide food mainly for African elephants.

C．They are home to many endangered animals.

D．They are attractive to plant-eating animals of different kinds.

The passage is developed mainly by________..

A．showing the effect and then explaining the causes

B．pointing out similarities and differences

C．describing the changes in space order

D．giving examples

A．Jerry Shay.	B．Steve Austad
C．Rich Miller	D．George Martin
