If you were a space traveler you might have to spend several months, or even years, in a spaceship. While you were in the ship you wouldn’t live as you usually do. You might have to find new ways to spend your time. Your body would have to adjust to different conditions. And you would have some problems that you never think about here on earth. For example, you would have to have a huge supply of food with you because you can’t go to the supermarket when you’re halfway to another planet. You also would need fresh water and a way to get rid of waste. In fact, there would be many problems to solve in order to live in space.

Scientists in the UK have announced that the piranhafish"s reputation 21 a fearsome 22 may well not be deserved. The fish, which is found in the Amazon in Brazil, have been 23 as deadly carnivores(食肉动物 ) that work in shoals to overwhelm their prey and strip it of its flesh in seconds.
However, experts 24 St Andrews University say that piranhas are omnivores(杂食动物) that mainly eat fish, plants and insects. They form. big groups not to hunt but to defend 25 against other predators, according to the team.
"Previously it was thought piranhas shoaled as it 26 them to form. a cooperative hunting group," said Professor Anne Magurran. " 27, we have found that it is primarily a defensive behavior. "
Piranhas can be attacked by animals 28 dolphins, caimans and large fish, so forming a shoal is a good way of 29 being killed. Piranhas of 30 age stay in the middle of the group for 31 and the 32 of the shoal differs according to the level of 33 When the water level is 34, the fish form. small groups as there is space to escape, but when the water level drops, they form. large groups as protection 35 predators.

Questions are based on the following passage.
When we accept the evidence of our unaided eyes and describe the Sun as a yellow star, we have summed up the most important single fact about it--at this moment in time. It appears probable, however, that sunlight will be the color we know for only a negligibly (微不足道的) small part of the Sun&39;s history.
Stars, like individuals, age and change. As we look out into space, we see around us stars at all stages of evolution.There are faint blooded dwarfs so cool that their surface temperature is a mere 4,000 degrees Fahrenheit; there are scaring ghosts blazing at 100,000 degrees Fahrenheit and
almost too hot to be seen, for the great part of their radiation is in the invisible ultraviolet range. Obviously, the "daylight" produced by any star depends on its temperature; today (and for ages
to come) our Sun is at about 10,000 degrees Fahrenheit, and this means that most of the Sun&39;s light is concentrated in the yellow band of the spectrum, falling slowly in intensity toward both
the longer and shorter light waves.
That yellow "hump" will shift as the Sun evolves,and the light of the day will change accordingly. (80) It is natural to assume that as the Sun grows older, and uses up its hydrogen fuel—which it is now doing at the spanking rate of half a billion tons a second—it will become steadily colder and redder.
What is the passage mainly about? 查看材料
A.Faint dwarf stars.
B.The evolution cycle of the Sun.
C.The Sun"s fuel problem.
D.The dangers of invisible radiation.

The Moon, which has undergone a distinct and complex geological history, presents a
striking appearance. The moon may be divided into two major terrains: the maria (dark
lowlands) and the terrace(bright highlands). The contrast in the reflectivity (the capability
of reflecting light) of these two terrains suggested to many early observers that the two
(5) terrains might have different compositions, and this supposition was confirmed by missions to
the Moon such as Surveyor and Apollo. One of the most obvious differences
between the terrains is the smoothness of the maria in contrast to the roughness of the
highlands. This roughness is mostly caused by the abundance of craters; the highlands are
completely covered by large craters(greater than 40-50 km in diameter), while the craters
(10) of the maria tend to be much smaller. It is now known that the vast majority of the Moon's
craters were formed by the impact of solid bodies with the lunar surface.
Most of the near side of the Moon was thoroughly mapped and studied from telescopic
pictures years before the age of space exploration. Earth-based telescopes can resolve
objects as small as a few hundred meters on the lunar surface. Close observation of
(15) craters, combined with the way the Moon diffusely reflects sunlight, led to the
understanding that the Moon is covered by a surface layer, or regolith, that overlies the
solid rock of the Moon. Telescopic images permitted the cataloging of a bewildering array
of land forms. Craters were studied for clues to their origin; the large circular maria were
(20) seen. Strange, sinuous features were observed in the maria. Although various land forms
were catalogued, the majority of astronomers' attention was fixed on craters and their
origins.
Astronomers have known for a fairly long time that the shape of craters changes as
they increase in size. Small craters with diameters of less than 10-15 km have relatively
(25) simple shapes. They have rim crests that are elevated above the surrounding terrain,
smooth, bowl-shaped interiors, and depths that are about one-fifth to one-sixth their diameters.
The complexity of shape increases for larger craters.
What does the passage mainly discuss?
A.What astronomers learned from the Surveyor and Apollo space missions
B.Characteristics of the major terrains of the Moon
C.The origin of the Moon's craters
D.Techniques used to catalogue the Moon's land forms

People landing at London’S Heathrow airport have something new to look at as they fly overBritain’S capital city.It is attractive,simple and a little strange.The Millennium Dome is a huge semi-circle of plastic and steel and it contains the largest public space in the world.It has been built to house an exhibition of all that is best in British life,learning and leisure. The Millennium Dome was designed by Sir Richard Rogers,one of British’S most famous architects.His work points the way to new developments in buildin9.Think of it as a giant symbol of the buildings in which we will all be living and working in the near future. Buildings are also a part of history.They express the culture of the times.Sir Richard Rogers is aware of this responsibility.While different designers have individual styles,their work also has a common style.That is:to express the values of the information age. What is an“information age”building?The dome is a good example.After the Millennium exhibition ends,it will be used for another purpose.Just as people no longer have“jobs for life”,modem buildings are designed for a number of different use for another Richard Roger’s building,the Pompidous Center(蓬皮杜艺术中心)in paris,uses the idea that information is communication.Instead of being hidden in the walls,heating pipes and elevators are open to public view.The Pompidous Center is a very honest building.It tells you how it works.
The Millennium Dome has been originally buih to hold an exhibition__________ .
A.of different building designing
B.of the finest things in Britain
C.of everything that can draw the attention of people
D.of recent developments in information technology
