United States President George W. Bush is expected to issue a directive in the next few weeks. It will give the US Air Force a green light for the development of space weapons, US media reported last week.
This would potentially start a new global arms race, some experts have warned.
To keep that from happening, last Wednesday the White House explained that it was not considering putting weapons in space. It said it was making a shift in
But some defense analysts and arms control advocates argue that the policy will pave the way for the US to put both defensive and offensive ( 攻擊性的) weapons in space.
“No one should be fooled,” said Theresa Hitchens, an American weapons expert.

The US Air Force wants to develop space- based weapons that could strike targets anywhere in the world within 90 minutes of receiving the order to open fire.
These new weapons under development cover a wide range. They include hunter- killer satellites and orbiting weapons. And they use lasers, radio waves, or even dense metal tubes, known as “ Rods from God”, dropped from space to do the damage.
There are many barriers to the setting up of this kind of program, experts say.
First is the coast. It is estimated that the budget may be US $220 billion to US $ 1 trillion ( 萬億).
The technical difficulties of developing reliable space weapons are also a problem.
And, the program will draw strong criticism from around the world. Experts worry about starting a space arms race.

Every year landslides {滑坡} cause 25 to 50 deaths and $1.5 billion in damage in the United States.They account for 15 percent of the deaths from natural disasters in Europe.And in Decem??ber, a single event killed more than 200 people in the Philippines.Sending workers to stabilize (加固) mountainsides using steel bars and cement (水泥) can help prevent disaster, but it introduces new difficulties.Shaking drills produce harmful dust and loosen heavy, dangerous debris (米屑)."It's quite a risky job," says Giorgio Pezzuto of D'Appolonia, an engineering company in Italy.
D'Appolonia, working with eight other companies, may have an answer: a three-ton robot called Roboclimber."The idea is to operate a machine far away that can drill without a hu??man being on board,'" says Pezzuto, manager for the project, which is supported by the European Commission.Engineers claim that the machine will be faster and cheaper than manual labor.The robot, a large radio-controlled four-legged me??chanical spider (蜘蛛), has cost at least $2 mil??lion so far.The final product should be able to climb unstable mountainsides, drill holes, insert bars and cement, and collect data on the slope' s stability.Testing should begin in May.
The underlined word "event" (in Paragraph l) refers to ___.
A.landslide B.machine C.earthquake D.flood
The purpose in writing this text is ___..
A.to tell people how serious the damage caused by landslides is
B.to tell people that sending workers to sta??bilize mountainsides is a risky job
C.to introduce a product that can be used to stabilize mountainsides
D.to show people how to use a new product
What does the robot look like?
A.A human being. B.A spider.C.A truck. D.A drill.
The biggest advantage of this product is that_________.
A.it will be faster and cheaper than manual labor
B.it can climb mountainsides, drill holes, insert bars and cement
C.it can collect data on the slope’s stability
D.it can drill without a human being on board
