The world anxiously watched as, every few hours, a hurtling chunk of comet plunged into the atmosphere of Jupiter. All of the twenty-odd fragments, collectively cal
2、led comet Shoemaker-Levy 9 after its discoverers, were once part of the same object, now dismembered and strung out along the same orbit. This cometary train, glistening like a string of pearls, had been first glimpsed only a few months before its fateful impact with Jupiter, and rather quickly scie
3、ntists had predicted that the fragments were on a collision course with the giant planet. The impact caused an explosion clearly visible from Earth, a bright flaming fire that quickly expanded as each icy mass incinerated itself. When each fragment slammed at 60 kilometers per second into the dense
4、atmosphere, its immense kinetic energy was transformed into heat, producing a superheated fireball that was ejected back through the tunnel the fragment had made a few seconds earlier. The residues from these explosions left huge black marks on the face of Jupiter, some of which have stretched out t
5、o form dark ribbons.Although this impact event was of considerable scientific import, it especially piqued public curiosity and interest. Photographs of each collision made the evening television newscast and were posted on the Internet. This was possibly the most open scientific endeavor in history
6、. The face of the largest planet in the solar system was changed before our very eyes. And for the very first time, most of humanity came to fully appreciate the fact that we ourselves live on a similar target, a world subject to catastrophe by random assaults from celestial bodies. That realization
7、 was a surprise to many, but it should not have been. One of the great truths revealed by the last few decades of planetary exploration is that collisions between bodies of all sizes are relatively commonplace, at least in geologic terms, and were even more frequent in the early solar system.1. The
8、passage mentions which of the following with respect to the fragments of cometShoemaker-Levy 9?(A) They were once combine in a larger body.(B) Some of them burned up before entering the atmosphere of Jupiter.(C) Some of them are still orbiting Jupiter.(D) They have an unusual orbit.2. The word colle
9、ctively in line 3 is closest in meaning to(A) respectively(B) popularly(C) also(D) together3. The author compares the fragments of comet Shoemaker-Levy 9 to all of the following EXCEPT(A) a dismembered body(B) a train(C) a pearl necklace(D) a giant planet4. Before comet Shoemaker-Levy 9 hit Jupiter
10、in July 1994, scientists(A) had been unaware of its existence(B) had been tracking it for only a few months(C) had observed its breakup into twenty-odd fragments(D) had decided it would not collide with the planet5. Before the comet fragments entered the atmosphere of Jupiter, they were most likely(

Superheated fireballs were produced as soon as the fragments of comet Shoemaker- Levy 9(A) hit the surface of Jupiter(B) were pulled into Jupiters orbit(C) were ejected back through the tunnel(D) entered the atmosphere of Jupiter7. The phrase incinerate
12、d itself in line 9 is closest in meaning to(A) burned up(B) broke into smaller pieces(C) increased its speed(D) grew in size8. Which of the following is mentioned as evidence of the explosions that is still visible onJupiter?(A) fireballs(B) ice masses(C) black marks(D) tunnels9. Paragraph 2 discuss
13、es the impact of the comet Shoemaker-Levy 9 primarily in terms of(A) its importance as an event of great scientific significance(B) its effect on public awareness of the possibility of damage to Earth(C) the changes it made to the surface of Jupiter(D) the effect it had on television broadcasting10.

Corn productio
15、n increased by four and a half times, hay by five times, oats and wheat by seven times. The most crucial factor behind this phenomenal upsurge in productivity was the widespread adoption of labor-saving machinery by northern farmers. By 1850 horse-drawn reaping machines that cut grain were being int
16、roduced into the major grain-growing regions of the country. Horse-powered threshing machines to separate the seeds from the plants were already in general use. However, it was the onset of the Civil War in 1861 that provided the great stimulus for the mechanization of northern agriculture. With muc
17、h of the labor force inducted into the army and with grain prices on the rise, northern farmers rushed to avail themselves of the new labor-saving equipment. In 1860 there were approximately 80,000 reapers in the country; five years later there were 350,000.After the close of the war in 1865, machin
18、ery became ever more important in northern agriculture, and improved equipment was continually introduced. By 1880 a self-binding reaper had been perfected that not only cut the grain, but also gathered the stalks and bound them with twine. Threshing machines were also being improved and enlarged, a
19、nd after 1870 they were increasingly powered by steam engines rather than by horses. Since steam-powered threshing machines were costly items running from $ 1,000 to $4,000 they were usually owned by custom thresher owners who then worked their way from farm to farm during the harvest season. Combin
20、es were also coming into use on the great wheat ranches in California and the Pacific Northwest. These ponderous machines sometimes pulled by as many as 40 horses reaped the grain, threshed it, and bagged it, all in one simultaneous operation.The adoption of labor-saving machinery had a profound eff
