A Plan For Exploring Mars
NASA is moving ahead with plans to put a long-armed lander on Mars' icy north pole to search for clues (线索) for water and possible signs of life.
The MYM386 million Phoenix Mars is planned to touch down in the Martian arctic in 2008.The stationary probe will use its robotic arm to dig into the icy land and pick up soil samples (标本,样品) to analyze. In 2002, the Mars Odyssey orbiter spotted evidence of ice-rich soil near the arctic surface.
Scientists hope the Phoenix mission will find clues to the geologic history of water on the Red Planet and determine whether microbes(微生物)existed in the ice.
Phoenix will be the first mission of the Mars Scout program, a renewed, low-cost effort to study the Red Planet. “The Phoenix mission explores new territory in the northern plains of Mars analogous to the permafrost regions on Earth,” Peter Smith said.
True to its name, Phoenix rose from the ashes of previous(先前的) missions. The lander for Phoenix was built to fly as part of the 2001 Mars Surveyor program. But the program broke down after the well-known disappearance of the Mars Polar Lander in 1999.The Polar Lander lost contact during a landing attempt near the planet's south pole after its rocket engine shut off prematurely,_causing the spacecraft to fall about 130 feet to almost certain destruction.
The Phoenix probe had been in storage at a Lockheed Martin clean room in Denver before it was reused for its present mission. It will carry science instruments that were designed for the Mars Surveyor program including an improved panoramic camera and a trench-digging robotic arm. Phoenix will lift off from the Kennedy Space Center in August 2007 and land on the planet nine months later.
1.The passage mainly tells readers that ________.
A.clues of water will be found in Phoenix
B.Phoenix will be sent to find clues of water on Mars
C.August 2007 will see Phoenix lift off
D.the Mars Scout program will be carried out
2.The underlined word “prematurely” (Paragraph 5) means “________”.
A.on time B.behind the time
C.out of work D.ahead of time
3.According to the passage, we know Phoenix will land on Mars ________.
A.in May 2008 B.in August 2007
C.in August 2008 D.in September 2008
4.According to the passage, the name “Phoenix” is after the meaning of ________.
A.rebirth B.death C.energy D.hope
5.After Phoenix lands on Mars, we can infer it will firstly ________.
A.find soil samples and send them to the earth
B.look for the icy land to dig for the soil samples
C.take photos and send them to the earth
D.find the remains of the Mars Polar Lander

A man was on the side of the road hitchhiking(搭便车)on a very dark night in the middle of a terrible rainstorm, with no cars on the road.The storm was so strong that the man could hardly see a few feet ahead of him.Suddenly, he saw a car come towards him and stop.The man, without thinking about it, got in the car and closed the door and only then did he realize that there was nobody behind the steering wheel(方向盘)!
The car started to move very slowly. The man looked at the road and saw a curve (拐弯处)coming his way. Terrified, he started to pray, begging for his life. He had not come out of shock when, just before the car hit the curve, a hand suddenly appeared through the window and moved the wheel. The man, paralyzed with fear, watched how the hand appeared every time the car was drawing near a curve.Finally, although terrified, the man managed to open the door and jump out of the spooky (幽灵般的)car. Without looking back, the man ran through the storm all the way to the nearest town. In a state of complete horror, the man walked into a nearby bar and asked for two glasses of Scotch whisky.
Then, still shaking with fright, he started telling everybody in the bar about the horrible experience he just went through in the spooky car. Everyone in the bar listened in silence and became frightened, with hair standing on end, when they realized the man was telling the truth because he was crying and he was certainly not drunk!
About half an hour later, two other young men walked into the same bar and one said to the other, “Hey, there’s a stupid man who jumped into the car while we were pushing it!”
【小题1】After he entered the car, the man found ____________.
| A.it didn’t move at all. | B.it moved very quickly. |
| C.there was no driver in it. | D.someone was pushing it. |

| A.it is unsafe for people to take a free ride |
| B.the man was telling a lie to his listeners |
| C.the car probably broke down on the way |
