Although my house was already full of cats anddogs, I still couldnt resist an occasional visit to the shelter. This time as I was walking down the row of pensfull of barking dogs I noticed a small boy looking into one of them.He had a malnourished（营养不良的） looking body and a bony face with a bignose sticking out of the middle of it. He was looking at a small, golden dog. Its bony ribs wereshowing and its thin tail was folded between its legs. It wasnt beggingfor attention like the other puppies but was hiding in the cornerinstead. The boy looked up at me with sad eyes and asked what was wrongwith it. “It was probably abused and abandoned”, I said. “That is why itis so scared.”The boy immediately turned to an older lady and said, “Grandma, I wantthis one.” The old woman smiled and walked to the front desk to fill outthe adoption forms. I followed and asked about the boy. I found out thathed had a rough start in life too. She had just gotten custody（监护权） of himafter the state had taken him from his parents. She had hoped getting adog would make it easier on him. I looked back at him, holding his scaredpuppy, and said a prayer for them both.It was yesterday. I was driving down the road enjoying a gloriously sunny,spring day. Then in a green front yard I saw the boy. His teenage body wastall and strong. His nose no longer seemed big but fit well into hissmiling face. He was throwing a ball to a healthy, happy dog with shininggolden hair. His little act of love and kindness had indeed gone a longway. It had saved a dogs life, healed his own heart, and given thismiddle-aged man fresh hope for us all.26.

Theories advanced so far have generally failed to explain the first step in continent growth, or have been subject to serious objections. It is the purpose of this article to examine the possible role of the impact of large meteorites or asteroids in the production of continental nuclei. Unfortunately, the geological evolution of the Earths surface has had an obliterating effect on the original composition and structure of the continents to such an extent that further terrestrial investigations have small chance of arriving at an unambiguous answer to the question of continental origin. Paradoxically, clues to the origin and early history of the surface features of the Earth may be found on the Moon and planets, rather than on the Earth, because some of these bodies appear to have had a much less active geological history. As a result, relatively primitive surface features are preserved for study and analysis. In the case of both the Moon and Mars, it is generally concluded from the appearance of their heavily cratered surfaces that they have been subjected to bombardment by large meteoroids during their geological history. Likewise, it would appear a reasonable hypothesis that the Earth has also been subjected to meteoroid bombardment in the past, and that very large bodies struck the Earth early in its geological history.The large crater on the Moon listed by Baldwin has a diameter of 285 km. However, if we accept the hypotheses of formation of some of the mare basins by impact, the maximum lunar impact crater diameter is probably as large as 650km. Based on a lunar analogy, one might expect several impact craters of at least 500km diameter to have been formed on Earth. By applying Baldwins equation, the depth of such a crater should be about 20km. Baldwin admits that his equation gives excessive depths for large craters so that the actual depth should be somewhat smaller. Based on the measured depth of smaller lunar crater. Baldwins equation gives the depth of the zone of brecciation for such a crater as about 75km. The plasticity of the Earths mantle at the depth makes it impossible to speak of “bracciation” in the usual sense. However, local stresses may be temporarily sustained at that depth, as shown by the existence of deep-focus earthquakes. Thus, short-term effects might be expected to a depth of more than 50km in the mantle.Even without knowing the precise effects, there is little doubt that the formation of a 500-km crater would be a major geological event. Numerous authors have considered the geological implications of such an event. Donn et al. have, for example, called on the impact of continent-size bodies of sialic composition to from the original continents. Two major difficulties inherent in this concept are the lack of any known sialic meteorites, and the high probability that the energy of impact would result in a wide dissemination of sialic material, rather than its concentration at the point of impact.Gilvarry, on the other hand, called on meteoroid impact to explain the production of ocean basins. The major difficulties with this model are that the morphology of most of the ocean basins is not consistent with impact, and that the origin and growth of continents is not adequately explained.We agree with Donn at al. that the impact of large meteorites or asteroids may have caused continent formation, but would rather think in terms of the localized addition of energy to the system, rather than in terms of the addition of actual sialic material.1. A mare basin isA. a formula for determining the relationship between the depth and width of craters. a valley that is filled in when a spatial body has impact with the moon or the earth.C. a planetoid (small planet) created when a meteorite, upon striking the moon, breaks off a part of the moon.D. a dark spot on the moon, once supposed to be a sea, now a plain.2. The writer does not believe thatA. an asteroid is larger than a meteorite. material from space, upon hitting the earth, was eventually distributed.C. the earth, at one time, had craters.D. ocean were formerly craters.3. The article is primarily concerned withA. the origin of continents. the relationship between astral phenomena and the moon.C. differences of opinion among authoritative geologists.D. the relationship between asteroids and meteorites.4. Sialic material refers toA. the broken rock resulting from the impact of a meteorite against the earth. material that exists on planets other than the earth.C. a composite of rock typical of continental areas of the earth.D. material that is man-made to simulate materials that existed far back in geological history.Vocabulary1. meteorit 陨石，陨星2. asteroid （火星和木星轨道间）小行星3. obliterate 除去，消减痕迹4. crater 火山口，陨石坑5. mare 海，（也指月亮，火星上的）阴暗区6. impact 撞击7. impact crater 陨石坑，撞击火山8. brecciate 合成角砾岩the zone of brecciation 角砾岩地带9. mantle 地幔10. stress 应力local stress 局部（本身）应力11. sialic 硅铝的12. probability 概率，可能性13. disseminate 传播，分散，浸染14. morphology 组织，结构，形态（学）15. astral 星（星状体）的难句译注1.
