swimming machines (og practice set 6)tunas, mackerels, and billfishes (marlins, sailfishes, and swordfish) swim continuously. feeding,courtship,reproduction, and even rest are carried out while in constant motion. as a result, practically every aspect of the body formand function of these swimming machines is adapted to enhance their ability to swim.many of the adaptations of these fishes serve to reduce water resistance (drag). interestingly enough,several of these hydrodynamic adaptations resemble features designed to improve the aerodynamics of high-speed aircraft. though human engineers are new to the game, tunas and their relatives evolved theirhigh-tech designs long ago.tunas, mackerels, and billfishes have made streamlining into an art form. their bodies are sleek and compact. the body shapes of tunas, in fact, are nearly ideal from an engineering point of view. most species lack scales over most of the body, making it smooth and slippery. the eyes lie flush with the body and do not protrude at all. they are also covered with a slick, transparent lid that reduces drag. the finsare stiff, smooth, and narrow, qualities that also help cut drag. when not in use, the fins are tucked intospecial grooves or depressions so that they lie flush with the body and do not break up its smoothcontours. airplanes retract their landing gear while in flightfor the same reason.tunas, mackerels, and billfishes have even more sophisticated adaptations than these to improve theirhydrodynamics. the long bill of marlins, sailfishes, and swordfish probably helps them slip through thewater. many supersonic aircraft have a similar needle at the nose.most tunas and billfishes have a series of keels and finlets near the tail. although most of their scaleshave been lost, tunas and mackerels retain a patch of coarse scales near the head called the corselet.the keels, finlets, and corselet help direct the flow of water over the body surface in such as way as toreduce resistance (see the figure). again, supersonic jetshave similar features.以上内容就是老托福阅读 100篇的部分内容介绍，托福备考阶段当让选择真题备考是再好不过了，如果考生们还看好以上内容话，就赶快下载吧!更多精彩资料稍后提供。

(435)1995.08question 1-9investigation of the deep-oceankeywords: ocean, researchers, techniques, samples, rocksthe ocean bottom – a region nearly 2.5 times greater than the total land area of the earth –that even today is largely unexplored and uncharted. until about a century ago, the deep – ocean floor wassubjected to intense pressures hundreds of times greater than at the earths surface, the deep – ocean bottomalthough 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 foundations deep sea drilling project (dsdp). using techniques first developed for the offshore oil and gas industry, the dsdps drill ship, the glomar challenger, was able to maintain a steady the ocean floor.the glomar challenger 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 glomar challengers coresamples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to calculate what it will probably look like millions of years in the future. today, largely on theof evidence gathered during the glomar challengers voyages, nearly all earth scientists agree on the theories of plate tectonics and continental drift that explain many of the geological processes that shape the earth.the cores of sediment drilled by the glomar challenger have also yielded information critical to understanding the worlds past climates. deep – ocean sediments provide a climatic record stretching backchemical 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.(a) is not a popular area for scientific research(b) contains a wide variety of life forms(c) attracts courageous explorers(d) is an unknown territory(a) uecognizable(b) ueachable(c) unusable(d) unsafe3. the author mentionsin line 5 because(a) the earths climate millions of years ago was similar to conditions in outer space(b) it is similar to the ocean floor in being alien to the human environment(c) rock formations in outer space are similar to those found on the ocean floor(d) techniques used by scientists to explore outer space were similar to those used in ocean exploration4. which of the following is true of the glomar challenger?(a) it is a type of submarine.(b) it is an ongoing project.(c) it has gone on over 100 voyages.(d) it made its first dsdp voyage in 1968.(a) breaking(b) locating(c) removing(d) analyzing6. the deep sea drilling project was significant because it was(a) an attempt to find new sources of oil and gas(b) the first extensive exploration of the ocean bottom(c) composed of geologists from all over the world(d) funded entirely by the gas and oil industry(a) basis(b) purpose(c) discovery(d)

the earths appearance hundreds of millions of years ago.(b) two geological theories became more widely accepted by scientists.(c) information was revealed about the earths past climatic changes.(d) geologists observed forms of marine life never before seen. questions 10-21basic to any understanding of canada in 20 years after the second world war is the countrys impressive population growth. for every three canadians in 1945, there were overin 1996. in september 1966depression of the 1930s and the war had held back marriages and the catching – up process began after 1945. the babyboom continued through the decade of the 1950s, producing a population increase of nearly fifteen percent in the five years from 1951 to 1956. this rate of increase had been exceededonly once before in canadas history, in the decade before 1911, when the prairies were being settled. undoubtedly, the good economic conditions of the 1950s supported a growth in the population, but the expansion also derived from astood at 28 per thousand, one of the highest in the world.stood at the lowest level in 25 years. partly this decline reflected the low level of births during the depression and the war, but it was also caused by changes in canadian society. young people were staying at school longer, more women were working, young married couples were buying automobiles or houses before starting families, rising living standards were cutting down the size of families. it appeared that canada was once more falling in step with the trend toward smaller families that had occurred all through the western world since the time of the industrial revolution.although the growth in canadas population has slowed down by 1966 (the increase in the first half of the 1960s was only nine percent). another large population wave was coming over the horizon.would be10. what does the passage mainly discuss?(a) educational changes in canadian society.(b) canada during the second world war(c) population trends in postwar canada(d) standards of living in canada11. according to the passage, when did canadas baby boom begin?(a) in the decade after 1911(b) after 1945(c) during the depression of the 1930s(d) in 1966(a) canadians(b) years(c) decades(d) marriages(a) new(b) extra(c) accelerating(d) surprising。
