D、Color (21) to make an animal difficult for its enemies to (22) . Many animals match their (23) so well that as long as they do not move no one is (24) to see them. You probably have often "jumped" a rabbit. If you (25) , you know how the rab- bit sits perfectly still (26) you are just a few feet away. You (27) see the rabbit till it runs for its (28) matches very closely the place where it is (29) . Many times you may have walked past a rabbit (30) didn’t run and you never knew it was there at all.
One of the most usual color schemes that helps animals to keep (31) being seen, is a dark back and light underpants. If an animal is the same color all (32) , there is always a dark shadow along the animal’s belly (腹部). (33) an enemy couldn’t see the animal he could see this dark shadow. The shadow makes the animal (34) out to view.But if the belly is (35) than the rest of the animal, the shadow will not be notice

5题:The ocean bottom, a region nearly 2.5 times greater than the total land area of theEarth, is a vast frontier that even today is largely unexplored and uncharteD、Until about a century ago, the deep-ocean floor was completely inaccessible, hidden beneath waters averaging over 3 600 meters deep. Totally without light and subjected to intense pressures hundreds of times greater than at theEarth’s surface, the deep ocean bottom is a hostile environment to humans, in some ways as forbidding and remote as the void of outer space.
Although researchers have taken samples of deep-ocean rocks and sediments for over a century, the first detailed global investigation of the ocean bottom did not actually start until 1968, with the beginning of the National Science Foundation’sDeep SeaDrilling ProjectDSDP). Using techniques first developed for the offshore oil and gas industry, theDSDP’s drill ship, the GlomarChallenger, was able to maintain a steady position on the ocean’s surface and drill in very deep waters, extracting samples of sediments and rocks from the ocean floor.
The GlomarChallenger completed 96 voyages in a 15-year research program that ended in November 1983,During this time, the vessel logged 600 000 kilometers and took almost 20 000 core samples of seabed sediments and rocks at 624 drilling sites around the worlD、The GlomarChallenger’s core samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to calculate what it will probably lo0k like millions of years in the future. Today, largely on the strength of evidence gathered during the GlomarChallenger’s voyages, nearly all earth scientists agree on the theories of plate tectonics and continental drift that explain many of the geological processes that shape theEarth.
The cores of sediment drilled by the GlomarChallenger have also yielded information critical to understanding the world’s past climates.Deep-ocean sediments provide a climatic record stretching back hundreds of millions of years, because they are largely isolated from the mechanical erosion and the intense chemical and biological activity that rapidly destroy much land-based evidence of past climates. This record has already provided insights into the patterns and causes of past climatic change information that may be used to predict future climates.
Which of the following is: true of the GlomarChallengerA.It is a type of submarine.
B.It is an ongoing project.
C.It has gone on over 100 voyages.
D.It made its firstDSDP voyage in 1968.
