阅读理解。     Astronauts aboard the space station celebrated a space first on Wednesday by drinking water that had
been recycled from their urine (尿), sweat and water got from air. They said "cheers" to NASA workers
on the ground.
     The urine recycling system is needed for astronaut stations on the moon and Mars. It also will save
NASA money because it won"t have to ship up as much water to the station by space shuttle or cargo rocket.
Besides, it"s important as the space station is about to expand (扩大) from three people living on board to
six.
     The recycling system had been brought up to the space station last November, but it couldn"t be used
until samples (样品) were tested back on earth. So when it came time to actually drink up, NASA made a
big deal of it. The three-man crew stood holding their drinks and congratulated engineers in two NASA
centers that worked on the system.
     "This is something that had been the stuff of science fiction," American astronaut Michael Barratt said
before taking a small mouthful. The taste is worth trying.
     The new system takes the combined urine of the crew from the toilet and moves it to a big tank, where
the water is boiled off, and the vapor is collected. The rest of the urine is thrown away. Then the water
vapor is mixed with water from air, and then it goes through filters (过滤器). When six crew members are
aboard, it can make about six gallons from urine in about six hours.
     "Some people may find the idea of drinking recycled urine distasteful, but it is also done on earth, but with
a lot longer time between urine and the tap," said Marybeth Edeen, the space station"s national lab manager.
     The technology NASA developed for this system has already been used for quick water purification (净化)
after the 2004 Asian tsunami. 1. According to the text, the recycling system is important because _____. [     ]
A. it makes traveling to the moon for the average person possible
B. with it NASA won"t need to ship any water up to the space station
C. it protects the environment in space by reducing the amount of waste
D. it can help meet the need for more water after the crew is expanded 2. Which is the RIGHT time order of the following events?
    a. The samples of the recycled water were tested on earth.
    b. Astronauts celebrated the space"s first making water from urine.
    c. The recycling system was brought up to the space station.
    d. The technology for the system was used to quickly purify water. [     ]
A. a, d, c, b
B. a, c, b, d
C. d, c, a, b
D. d, a, c, b 3. From Paragraph.5 we can know _____. [     ]
A. the process of recycling urine
B. the effect of the recycling system
C. an opinion on recycling urine
D. the theory behind the recycling system 4. What is the best title for the text? [     ]
A. Drink up: Space Station Recycles Urine to water
B. New Technology Is Used in the Space Station
C. The Research of NASA Has Made Great Progress
D. Good News: Water Recycled from Urine Tastes Good

阅读理解。     Spread out a map of the world. What you see on it depends on the kind of map you have. Does it show
cities and countries? Mountains and valleys? Maybe weather patterns? The variety of features is so great that
one map just can"t handle them all.
     The earth is part of a nine planets solar system within the Milky Way galaxy. Its size and location aren"t
very impressive. We inhabit the third planet from the Sun, which is only the fifth largest overall. Yet The earth
has a talent for creating life. In fact, it"s the only place that has life so far!
     One form of life humans tends to take this for granted. Human activities like habitat destruction, pollution,
and over-fishing have badly damaged life as we know it. Luckily, Earth is as tough as it is beautiful. But it
doesn"t take an expert to see that one planet can only take so much. 1. In the _____, there are _____ planets in all. [     ]
A. Milky Way galaxy; 7
B. solar system; 8
C. solar system; 9
D. Milky Way galaxy; 10 2. The earth is the _____ largest planet in the solar system and the _____ planet from the Sun. [     ]
A. fifth; third
B. third; fifth
C. second; third
D. third; sixth 3. As is known to us all, _____ has badly damaged the earth life. [     ]
A. habitat destruction
B. pollution
C. over-fishing
D. all of the above

阅读理解。     A long time ago people thought that the sun went round the earth. In some countries people even said that
the sun was a god (神). They thought the god drove across the sky each day on a golden horse. Now we
know the earth goes round the sun. It takes the earth a year to go all way round the sun. Today men even
know how far it is for the earth to go round the sun. They tell us that the earth travels over a thousand miles
a minute on its journey round the sun.
     The sun is really a star. It is much bigger than the earth and it is very hot. Some people have been to the
moon but we know that no one can ever go to the sun. It is far too hot for people to live anywhere near it.
The sun is three hundred thousand times heavier than the earth and more than million times larger. 1. A long time ago, people said the sun was _____. [     ]
A. a golden horse of god
B. a god on a golden horse

阅读理解。     Monarch butterflies (黑脉金斑蝶) are a common summer sight in the northern United States and Canada.
These large orange and black insects (昆虫) brighten parks and gardens as they fly lightly among the flowers.
What makes monarchs particularly interesting is that they migrate (迁飞)-all the way to California or Mexico
and back. They are thought to be the only insect that does this.
     Every year in the late summer monarchs begin their journey to the south. Those heading for Mexico go first
for the Louisiana-Mississippi area, then fly across the Gulf of Mexico into Texas. Once in Mexico, they settle
themselves in one of about fifteen places in a mountain forest filled with fir trees. Each place provides a winter
home for millions of monarchs. The butterflies are so many that they often cover entire trees. When spring
comes, they begin their long journey north.
     The question is often asked whether every butterfly makes the round-trip journey every year. And the answer
is no. The average monarch lives about nine months. So one flying north might lay eggs in Louisiana and then
die. The eggs of that generation may be found in Kentucky; the eggs of the next generation may end up in
Wisconsin or Michigan. The last generation of the season, about the fourth, will make their way back to Mexico
and restart the journey.
     Scientists learn about monarchs" migration by catching and making marks on the insects. By recatching a
monarch with such a mark and noticing where it came from, the next scientist can get to know things like the
butterfly"s age and its routing (路线). 1. One of the places where monarchs spend the winter is _____. [     ]
A. the Gulf of Mexico
B. an area in Mississippi
C. a forest in Mexico
D. a plain in Texas 2. The routing of monarchs" migration can be learned _____. [     ]
A. by collecting their eggs in the mountains
B. by examining the marks made on them
C. by comparing their different ages
D. by counting the dead ones in the forests 3. What is the subject discussed in the passage? [     ]
A. Life and death of monarchs.
B. Scientists" interest in monarchs.
C. Winter home of monarchs.
D. Migration of monarchs.

阅读理解。     The fiddler crab (蟹) is a living clock. It indicates the time of day by the colour of its skin, which is dark
by day and pale by night. The crab"s changing colour follows a regular twenty-four hour plan that exactly
matches the daily rhythm of the sun.
     Does the crab actually keep time, or does its skin simply answer to the sun"s rays, changing colour
according to the amount of light which strikes it? To find out, biologists kept crabs in a dark room for two
months. Even without daylight, the crab"s skin colour continued to change exactly on time.
     This characteristic probably developed gradually in answer to the daily rising and setting of the sun, to help
protect the crab from sunlight and enemies. After millions of years it has become completely controlled inside
the living body of the crab.
     The biologists noticed that once each day the colour of the fiddler crab is especially dark, and that each day
this happens fifty minutes later than on the day before. From this they discovered that each crab follows not
only the rhythm of the sun but also that of the tides (潮水). The crab"s period of greatest darkening is exactly
the time of low tide on the beach where it was caught! 1. The crab"s changing colour _____. [     ]
A. tells the crab what time it is
B. protects the crab from the sunlight and enemies
C. keeps the crab warm
D. is of no real use 2. When the fiddler crabs were kept in the dark, they _____. [     ]
A. did not change colour
B. changed colour more quickly
C. changed colour more slowly
D. changed colour on the same timetable 3. The crab"s colour-changing ability was probably developed _____. [     ]
A. in the process of evolution (进化)
B. over millions of years
C. by the work of biologists
D. both A and B 4. The best title for this selection would be _____. [     ]
A. The Sun and the Tides
B. Discoveries in Biology
C. A scientific Study
D. A Living Clock
