[单项选择]Passage Three
Some desert regions get no rainfall for months, and even years. Yet water can be found if you dig deep enough. For a long time this was a puzzling question. Then geologists found the answer. The underground water is rainwater--but the rain fell hundreds of miles away! It soaked into the ground and then flowed underground through a rock sandwich.
A rock sandwich with water in the filling has a scientific name: aquifer. An aquifer is composed of two or more layers of nonporous rock. That’s the bread of the sandwich. The filling is a layer of porous rock or sand. The whole sandwich, or aquifer, is titled at a slant. The higher end is in a region of good rainfall, where the rain soaks into the porous rock or sand. The rainwater flows down at a slant between the nonporous rock layers. If a well is drilled through the top layer, the water flows up into the well.
If the upper end of the aquifer is higher than the top of the well, the water is forc
A. weather patterns
B. boundaries and land claims

[填空题]The fastest warming is taking place in the regions around the South Pole, where glaciers are disappearing at an astonishing speed.

[单项选择]There are warm tropical regions all over the globe, but only the Indians of the South American rain forests have formed the habit of sleeping in the open air. Long before they made painful acquaintance (相识) with Europeans, they had invented something that was unique on earth: the hammock.
Nobody really knows who first had the bright idea of making sleeping in the air the symbol of untroubled rest. The Indians see the hammock as a "gift of heaven (上天)", something given to them a very long time ago.
In it the Indians pass away hot noon hours, napping or chatting. Swinging it to and fro (来回摆动) creates a cooling breath of air and keeps away insects. They work and play in hammocks, are born and die there.
Hung like a suspension bridge between heaven and earth, a hammock is dry while the soil is damp and is safe from most wild animals.
Hammocks have the advantage over beds in that they are easy to transport and take up very little space when they have been rolled
A. a suspension cage which can be swung to and fro in the air
B. a seat hanging by two ropes from the branch of a tree
C. a suspension bridge in the South American rain forests
D. a net hung between two supports and used as a bed

[单项选择]　　That large regions of the galaxy can be influenced by the formation of massive stars in a few localized regions requires that star formation somehow be coordinated over long periods of time. The process commences with a single O-type star or a cluster of such stars in a giant molecular cloud, around which stellar radiation, winds and explosions carve a modest cavity from of the surrounding interstellar medium, concomitantly destroying the progenitor cloud. Perchance this disturbance triggers star formation in a nearby cloud, and so on, until the interstellar medium in this corner of the galaxy resembles Swiss cheese, composed of what theorists have recently begun to refer to as bubbles, or superbubbles, one of the most exciting discoveries in astrophysics in years. Within a hot bubble, the sun has revealed itself in x-rays emitted by highly ionized trace ions such as oxygen and at some point in the process of its formation, nearby bubbles commence to overlap, coalescing into a superb
A. A star is discovered that emits lower levels of trace ions than those discovered by x-rays of our galaxy’’s sun.
B. A section of the universe is discovered to lack both stars and any sort of interstellar medium.
C. A galaxy is discovered with a negative rate of star formation.
D. In one corner of the galaxy, coronal gas is discovered to rarify as it becomes cooler.
E. A superbubble is found of equal mass to the galaxy surrounding it.
