If asked if space exploration should continue, most Americans would give an immediate response either in favor of continuing or in favor of ending space exploration. A common response would be that space exploration is a waste of money. An average American, uneducated on the subject, might believe that the government is wasting billions of dollars on the research that has no merit. Someone strange to the subject might say that a space shuttle goes up once in a while and that is about all that happens. Research is ongoing and continues when there are no shuttles being launched. This also costs the government money. Does the extreme cost of space exploration make sense?
One argument is that the government is wasting money on the research not being used on Earth. Actually, the money goes to workers and scientists that support National Aeronautics and Space Administration (NASA) missions (任务), and goes to major companies that play important roles in major sectors of the US economy. Boeing is a partner of NASA for aircraft, the same company that makes commercial aircraft for the airline industry.
Another benefit to continuing space exploration is the many spinoff (衍生的) technologies it provides. The artificial heart resulted from experiments on the space shuttle. The handheld Jaws of Life used to save victims from car accidents originated from the system used to separate the space shuttle from its booster rockets. Insulation in homes that keeps them warm and energy efficient is based on the technology used to insulate the space shuttle.
There are direct benefits to the economy provided by NASA missions as well as spinoff technologies. These advances are found in food, building materials, medical procedures and the vehicles we drive. While it can be proven that billions of dollars that could be used elsewhere is being spent on space exploration, the benefits it provides outweigh the terrible aspects. As a matter of fact, the money spent helps to improve the quality of our lives.
1.How is Paragraph 2 mainly developed?
A. By offering analyses.
B. By making comparisons.
C. By giving some examples.
D. By presenting research findings.
2.The function of Jaws of Life is to _____.
A. save people from traffic accidents
B. do experiments on the space shuttle
C. keep houses warm and energy efficient
D. separate the space shuttle from its booster rockets
3.In the author’s opinion, space exploration _____.
A. has changed our life completely
B. costs too much of our time
C. benefits us in many ways
D. has nothing to do with us
4.What would be the best title for the text?
A. Benefits of space exploration
B. Is space exploration worth the cost?
C. How to make space exploration affordable
D. Missions of the NASA space shuttle program

As in the field of space travel, new technologies continue to appear in undersea exploration.They share a number of similarities with each other — as well as some important differences.
Manned submersibles (潜水器), like spaceships, must maintain living conditions in an unnatural environment.While a spaceship must simply be sealed against the vacuum space, a submersible must be able to bear extreme pressure if it is not to break up in deep water.
In exploring space, unmanned vehicles were employed before astronauts.In undersea exploration, on the other hand, men paved the way, and only recently have unmanned remote-operated vehicles (ROVs) been put to use.
One reason for this is that communicating with vehicles in orbit is much easier than talking to those underwater.A vacuum is an ideal medium for radio communications, but underwater communications are limited to much slower sound waves.Thus, most undersea vehicles — particularly ROVs — operate at the end of long ropes.(电缆终端)
For a similar reason, knowing where you are undersea is much more difficult than in space.A spaceship’s position can be located by following its radio signal, or by using telescopes and radar.For an undersea vehicle, however, a special network of sonar (声纳系统)devices must be laid out in advance on the ocean floor in the area of a dive to locate the vehicle’s position.
Though undersea exploration is more challenging than outer space in a number of respects, it has a distinct advantage: going to the ocean depths doesn’t require the power necessary to escape Earth’s gravity.Thus, it remains far less expensive.
1.The purpose of the passage is ______.
A.to persuade you to explore the depths of the ocean
B.to stress the importance of the undersea exploration
C.to make you believe that the undersea exploration is better
D.to tell some differences between two kinds of explorations
2.By saying “men paved the way” in Paragraph 2 the author means that in undersea exploration ______.
A.unmanned vehicles were used in the beginning
B.men covered the ocean floor with stones and bricks
C.manned vehicles were employed before unmanned ones
D.men invented unmanned remote-operated vehicles in the past
3.The sonar devices must be placed ______.
A.from time to time
B.after the undersea vehicles dive
C.before the undersea vehicles dive
D.when the undersea vehicles are diving
4.What can we infer from the passage?
A.Submersibles usually break up in deep water.
B.Undersea vehicles can receive signals immediately.
C.Going to space needs power to escape the gravity.
D.Radio communications are quite difficult in a vacuum.

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
If you like exploring the wilderness, you should read the following suggestions from search-and-rescue rangers(搜救队) in the national parks. 1
Before you head out on a hike, check the weather, take plenty of water, and make sure someone knows where you’ll be and when you’ll be back. Bring clothes to keep you warm when wet, like a waterproof jacket. Avoid cotton, which traps damp. 2 Take basic precaution, such as waterproof matches, a folding saw, a good knife, a first-aid kit, a flash light, and batteries.
The minute you think you might get lost, stop. 3And you should stay calm and think rationally(理性地). If you are not alone, focusing on the needs of others can help hold your own fears at bay. Keeping a sense of humor helps too.—it reduces stress and promotes creative thinking.
In general, people who try to find their own way out are far worse than those who stay put(呆在原处). 4 In a wide-open area, make a signal with colorful gear, make a big X out of rock, or dig a shallow trench, which are easy to spot from above.
You can go several days without eating, so in most cases, you’d better not search for food, since there are lots of poisonous plants in the wild. But you need to stay hydrated(含水的). 5If you are lost in your car, stay there: You are more visible to rescuers. And the car provides shelter.
A.Stay visible so anyone searching can see you.
B.First, you’ve got to acknowledge you’re in trouble.
C.And you have no idea where to go.
D.The search-and-rescue people call it death clothes.
E. First of all find a shelter and stay in it in order to keep dry.
F. These suggestions may keep you alive in emergencies.
G. If you run out of water, It’s usually better to drink from a stream with suspect water than to go without.
