Space is where our future is — trips to the Moon, Mars and beyond. Most people would think that aside from comets(彗星) and stars, there is little else out there. But, since our space journey started we have left so much trash(垃圾) there that scientists are now concerned that if we don't clean it up, we may all be in mortal (致命的)danger.
The first piece of space junk was created in 1964, when the American satellite Vanguard I stopped operating and lost its connection with the ground center. However, since it kept orbiting around the Earth without any consequences, scientists became increasingly comfortable abandoning(抛弃) things that no longer served any useful purpose in space.
It is estimated (估计)that there are now over 500,000 pieces of man-made trash orbiting the Earth at speeds of up to 17,500 miles per hour. The junk varies from tiny pieces of paint chipped off rockets to cameras, huge fuel tanks, and even odd items like the million-dollar tool kit that astronaut Heidemarie Stefanyshyn Piper lost during a spacewalk.
The major problem with the space trash is that it may hit working satellites and damage traveling spacecraft(飞船). Moreover, pieces of junk may collide(碰撞) with each other and break into pieces which fall back to the Earth. To avoid this, scientists have invented several ways for clearing the sky. Ground stations have been built to monitor larger pieces of space trash to prevent them from crashing into working satellites or space shuttles. Future plans include a cooperative effort among many nations to stop littering in space and to clean up the trash already there.
1.What was the first piece of man-made space trash?
A. A camera. B. A tool kit.
C. A fuel tank. D. A broken satellite.
2.Why were scientists NOT concerned about space trash in the beginning?
A. It no longer served any useful purpose.
B. It was millions of miles away from the Earth.
C. It did not cause any problems.
D. It was regarded as similar to comets and stars.
3. Which of the following statements is true about space junk?
A. It is huge, heavy machines.
B. It never changes position.
C. It floats slowly around the Earth.
D. It may cause problems for space shuttles.
4. What has been done about the space trash problem?
A, Scientists have cleaned up most of the trash.
B. Large pieces of space trash are being closely watched.
C. Many nations have worked together to stop polluting space.
D. Ground stations are built to help store the trash properly in space.

Have you ever had that fantasy to visit the moon, grab a rock and throw it into space so it would float forever? Soon, if you have got the cash, you can!
Enter the Artemis Project. This new and exciting project is a private one that will “establish a permanent, self-supporting manned lunar base,” which translates into a community on the moon for people to live in. “It’s not a question of whether it’ll work, but rather how long it will take.” according to Gregory Bennett, the founder of the Artemis Project
On July 20, 1969, Neil Armstrong became the first man to set foot on the moon. That moment became a great achievement in both the space community and for humanity itself. Despite the significance of occasion, almost certainly when viewers saw images of his weightless, bouncing (弹跳) figure they thought, “That looks like fun!”
So the Artemis team is taking realistic approach to a human fantasy: they are marketing the project of a lunar base as pure entertainment.
Veronis, Suhler & Associates are investment bankers for the communications and media industry. Their research found that Americans spent over 40 billion dollars to be entertained in the movies, through home videos and television in 1999.
California investor, Dennis Tito, recently took a trip to the International Space Station, after donating $20 million dollars to the Russian Space program. Wealthy celebrities like Canadian director James Cameron and the brothers of rock band Oasis have also voiced their interest to visit the big ball in the sky. In the same report by Veronis, Suhler & Associates, consumers spent close to 4 billion dollars on video-game software alone. So, for $1.42 billion dollars the Artemis Project is a drop in the entertainment bucket.
University student, Al Dharsee says, “I would certainly go to the moon, if given the opportunity, so that I could look at the earth and laugh. But with the way we treat our own planet, I don’t think we deserve to set foot on any planets or moons for that matter.
However, if you’re one of those ready to book a flight, don’t pack your bags quite yet, your flight is not scheduled to depart for at least a couple of decades.
1.What is the Artemis Project aimed at?
A. Maintaining a manned lunar base.
B. Providing a new kind of entertainment.
C. Offering some community-based facilities.
D. Finding facts about the first exploration to the moon.
2. What did Veronis, Suhler& Associates find through their research?
A. Wealthy celebrities donated a lot of space programs.
B. The Artemis Project would cost less than $1.42 billion dollars.
C. Americans paid a large amount of money for entertainment.
D. More than $40 billion are spent on communications and media industries in 1999.
3.What does Al DHarsee imply?
A. Most planets deserve to be employed.
B. Human beings may destroy the moon.
C. It costs too much to destroy the environment.
D. The trip to the moon doesn’t appeal to him.
4.This text may be taken from .
A. a fiction story.
B. an advertisement.
C. an entertainment report.
D. a business survey.

Fascinated with images from the Mars Rover? It turns out you don’t have to go to space. The following spots may look like they are on another planet, but they are right here on earth.
* Socotra Island, Indian Ocean
The largest of the four-island Socotra Archipelago, the island has about 250 species of plants that are not found anywhere else in the world. This includes the canopy-topped dragon’s blood tree, which has blood-red resin(树脂)that runs down if the trunk is cut deep. It can grow to 10 feet with a bulbous(球根的)trunk that swells with water absorbed in case of dry weather.

This wilderness in Northern Arizona/southern Utah is home to some of the most striking landscapes in the American Southwest. The nearly 300,000-acre site is known for its abundance of colorful shale(页岩)and Navajo sandstone that has been eroded(侵蚀)by the elements to create cliffs that rise as high as 3,000 feet. In the northwest of the park is the Coyote Buttes, where you’ll find The Wave, a wall of red sandstone that twists and turns in a way that just doesn’t look natural ---but is.
See it for yourself: Permits are required to hike in Vermilion Cliffs. Paria Canyon and Buckskin Gulch permits are available at on-site pay stations or in advance ($5 per person).

But with ever increasing ease, the shuttle __ _ and roars into the sky, headed into space at a _ of over 17,000 mph.
It is within the first two minutes to launch the Space Shuttle that the great success lesson is . Fact: 85% of the shuttle’s fuel is consumed within the first two minutes just to get the 15-story super structure to its orbital altitude.
And that’s exactly how success : The first steps you take towards launching a successful career are the and will require an enormous consumption of energy—a great big push. However, you persist through the launch period, which can seem almost for quite some time, everything gets easier and easier and your results get bigger and bigger.
