　　Scientists used to explore(探测)on the surface of the ocean．Now they are exploring below the surface, too．They want to know about ocean water and the plant and animal life deep in the ocean．

　　In 1934 the scientist William Beebe dived 3000 feet below the surface in a hollow steel ball．In 1935 August Piccard dived 10 330 feet．In 1960 his son Jean dived to a depth of 35 800 feet．

　　All these early dives were deep．But the divers could not stay down for very long．They had to come back up to the surface after a few seconds．Scientists needed to stay down longer to study life below surface．Gradually they succeeded．Cousteau, a Frenchman, was able to keep men down to a depth of 36 feet for one month and to a depth of 90 feet for a week．

　　Now scientists are developing even better equipment．With this new equipment, men can stay below the surface for days or even weeks．In 1962 Cousteau set up a research station 35 feet below the surface．Then, in 1964,he set up another station on the ocean floor of the Red Sea．This was the first undersea station to operate without help from the surface．

　　Many countries are now studying undersea living．The former Soviet Union has an undersea laboratory in the Crimean Sea．The United States has a laboratory 50 feet down on the ocean floor off the Virgin Islands．In 1970 five men lived there for two weeks．Then a team of five women scientists stayed in the laboratory．Next came other teams of men．All were there to explore the ocean depths and to make plans for the use of its resources．Scientists hope to find enough mineral, vegetable, and animal wealth there to provide food for the entire world．

(1)

In order to ________, scientists are exploring below the surface of the ocean．
[　　]
A．	know about the ocean water deep in the ocean
B．	stay down longer to study life of the plant and animal below the surface
C．	know about the plant and animal life deep in the ocean
D．	both A and C

(2)

Who made the deepest dive?
[　　]
A．	William Beebe．
B．	August Piccard．
C．	Jean Piccard．
D．	Cousteau．

(3)

Who set up the first undersea station?
[　　]
A．	A Frenchman．
B．	An American．
C．	A Russian．
D．	The passage made no mention．

(4)

Which of the following statements is true?
[　　]
A．	The early divers could not stay down for very long．
B．	Up to now only five women scientists have stayed in the undersea laboratory．
C．	The purpose of setting up the undersea laboratories is to make plans for the use of the resources in the ocean．
D．	None of the above is true．

(5)

The author wants to tell us ________．
[　　]
A．	that scientists try to explore the ocean depths
B．	that scientists try to make use of resources in the ocean
C．	about the secret of the plant and animal life in the ocean
D．	both A and B

答案：1．D;2．C;3．A;4．A;5．D;
解析：

(1)	由第一段“They want to know about ocean water and the plant and animal life deep in the ocean”可知。
(2)	第二段中将到William Beebe 潜水的深度是1000 feet, August Piccard潜水的深度是10 330 feet, Jean Piccard(August Piccard的儿子)潜水的深度是35 800 feet，没有谈到Cousteau潜水的深度。
(3)	Cousteau是一个法国人，在第三段有交代。由第四段的“In 1962 Cousteau set up a research station 35 feet below the surface．Then, in 1964, he set up another station on the ocean floor of the Red Sea．This was the first undersea station to operate without help from the surface．”可知。
(4)	第三段“All these early dives were deep．But the divers could not stay down for very long”证明A项是正确的，第五段虽然有“Then a team of five women scientists stayed in the laboratory”的说明，但并不证明“Up to now only five women scientists have stayed in the undersea laboratory”，所以B项是错误的，“make plans for the use of the resources in the ocean”只是科学家建深水实验室的目的之一，所以C项是错误的。
(5)	由第五段“All were there to explore the ocean depths and to make plans for the use of its resources．Scientists hope to find enough mineral, vegetable, and animal wealth there to provide food for the entire world”可知。

　　Thirteen vehicles lined up last March to race across the Mojave Desert, seeking a million in prize money．To win, they had to finish the 142-mile race in less than 10 hours．Teams and watchers knew there might be no winner at all, because these vehicles were missing a key part－drivers．

　　DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields．But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance．One had its brake lock up in the starting area．Another began by throwing itself onto a wall．Another got tied up by bushes near the road after 1.9 miles．

　　One turned upside down．One took off in entirely the wrong direction and had to be disabled by remote(远距离的)control．One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock．The “winner,” if there was any, reached 7.8 miles before it ran into a long, narrow hole, and the front wheels caught on fire．

　　“You get a lot of respect for natural abilities of the living things, ” says Reinhold Behringer, who helped design two of the car-size vehicles for a company called Sci-Autonics．“Even ants(蚂蚁)can do all these tasks effortlessly．It’s very hard for us to put these abilities into our machines．”

　　The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately．Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there’s a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good．She is more advanced, even months old, than any machine humans have designed．

(1)

Watchers doubted if any of the vehicles could finish the race because ________．
[　　]
A．	they did not have any human guidance
B．	the road was not familiar to the drivers
C．	the distance was too long for the vehicles
D．	the prize money was unattractive to the drivers

(2)

DARPA organized the race in order to ________．
[　　]
A．	raise money for producing more robotic vehicles
B．	push the development of vehicle industry
C．	train more people to drive in the desert
D．	improve the vehicles for future wars

(3)

From the passage we know “robotic vehicles” are a kind of machines that ________．
[　　]
A．	can do effortlessly whatever tasks living things can
B．	can take part in a race across 142 miles with a time limit
C．	can show off their ability to turn themselves upside down
D．	can move from place to place without being driven by human beings

(4)

In the race, the greatest distance one robotic vehicle covered was ________．
[　　]
A．	about eight miles
B．	six miles
C．	almost two miles
D．	about one mile

(5)

In the last paragraph, the writer implies that there is a long way to go ________．
[　　]
A．	for a robotic vehicle to finish a 142-mile race without any difficulties
B．	for a little child who has just learned to walk to reach the cookie on the table
C．	for a robotic vehicle to deal with a simple problem that a little child can solve
D．	for a little child to understand the importance of wiping apple juice off its face
