According to preliminary market surveys, there are 10,000 would-be space tourists willing to spend $1 million each to visit the final frontier. Space Adventures in Arlington have taken more than 130 deposits for a two-hour, $98,000 space tour tentatively set to occur by 2005. This may sound great, but there are a few hurdles: Putting a simple satellite into orbit--with no oxygen, lift: support or return trip necessary—already costs an astronomical $2,200/kg. And that doesn't include the cost of insuring rich and possibly litigious (爱打官司的) passengers. The entire group of entrepreneurs trying to comer the space- tourism market has between them "just enough money to blow up one rocket".
The U.S. space agency has plenty of money but zero interest in making space less expensive for the little guys. So the little guys are racing to do what the government has failed to do: design a reusable launch system that's inexpensive, safe and reliable. Kelly Space's prototype looks like a plane that has sprouted rocket engines. Rotary Rocket in California has a booster with rotors to make a helicopter-style. return to earth. The first passenger countdowns arc still years away, but bureaucrats at the Federal Aviation Administration in Washington arc already informally discussing flight regulations. After all, you can't be too prepared for a trip to that galaxy far, far away.
Which of the following is the best title for the passage？
A．Take Vacations in Space
B．Building Hotels in Space
C．Flight Regulations in Space Travels
D．Cost of Space Traveling
The heated air above a fire rises in a pillar of smoke and burnt gases, pulling fresh air in from the sides to replace it. Firefighters use this fact when they "fight fire with fire." They start a fire well in front of the one which they are fighting. Instead of traveling on in front of the huge fire, the smaller fire is pulled back toward it by the updrafts of the larger blaze. As it travels back to meet the large fire, the smaller backfire burns away the fuel that the forest fire needs to survive.
Even when a backfire has been well set, however, the fire may still win the struggle. The wind which the firefighters used to help them may now become their enemy. When the backfire meets the main fire, before both die for lack of fuel, there is tremendous flame, great heat and wild winds. A strong gust may blow the fire into the treetops beyond the area, giving the fire new fuel and a new life.
This passage focuses on ______.
A．how fires start
B．damage caused by fire
C．the fascination of fire
D．fighting forest fires
Passage One
Questions 21 to 25 are based on the following passage.
Your passport is your official identification as an American citizen. In America，most people never consider obtaining a passport unless they are planning a trip out of the country. In Europe, where travel from one country to another is much more common，almost everyone carries a passport. A passport is final proof of identity in almost every country in the world.
In 1979 almost 15 million Americans held passports. Most of these passports were obtained to travel outside the country because，except for a few Western nations。passports are required to enter every country. And if you travel abroad，you must have a valid passport to reenter the country.
When traveling abroad，you will need a passport for identification when exchanging dollars for francs or marks or other foreign currency. You may also need your passport to use a credit card，buy an airplane ticket or check into a hotel. As a passport is an official U. S. document. it is valuable as identification in any emergency cases，such as floods，fires，or war.
Don't confuse passports and visas. Whereas a passport is issued by a country to its citizens. a visa is official permission to visit a country granted by the government of that country. For some years，many countries were dropping their visa requirements，but that trend has reversed. Argentina，Brazil，and Venezuela now require visas from U. S. citizens. They may be obtained from the embassy of the country you wish to visit.
Passport applications are available at passport agency offices in large cities like Boston，New York，or Chicago. In smaller cities，applications are available at post offices and at federal courts. To get your first passport，you must submit the application in person. along with a birth certificate and two pictures.
The main purpose of this passage is to______.
A. discuss traveling in other countries
B. distinguish between passports and visas
C. discuss the financial uses of a passport
D. provide information about passports
