orbit of one particular comet was a very difficult mathematical problem.He could not figure it out.Neither could other scientists who dealt with such problems.However，Halley had a friend named Newton，who was a brilliant mathematician.Newton thought he had already worked out that problem，but he could not find the papers on which he had done it.He told Halley that the orbit of a comet had the shape of an ellipse(椭圆)Now Halley set to work.He figured out(解决；计算出) the orbits of some of the comets that had been observed by scientists.He made a surprising discovery.The comets that had appeared in the years 1531,1607，and 1682 all had the same orbit.Yet their appearances had been 75 to 76 years apart.This seemed very strange to Halley.The different comets followed the same orbit.The more Halley thought about it，the more he thought that there had not been three different comets，as people thought.He decided that they had simply seen the same comet three times.The comet had gone away and had come back again.It was an astonishing idea！Halley felt certain enough to make a prediction(预言) of what comet would happen in the future.He decided that this comet would appear in the year 1758.There were 53 years to go before Halleys prediction could be tested. In 1758 the comet appeared in the sky.Halley did not see it，for he had died some years before.Ever since then that comet has been called Halleys comet，in his honor.1Edmund Halley figured out the orbit of_.Asome different comets appearing several timesBthe same comet appearing at different timesCthree different comets appearing three timesDseveral comets appearing at the same time2Halley made a surprising，but correct prediction in the year_.A1704B1705C1706D17073This passage in general is about_.AHalley and other scientistsBthe orbit of a cometCNewton and HalleyDHalley and his discovery4Which of the following is TRUE?AEdmund Halley was an American scientist.BHalley made his discovery by doing experiments.CNewton was a famous mathematician.DThe orbit of a comet had the shape of an around.翻译句子1很久以前在地球上存在着体形庞大的动物。(exist)_2现在轮到她为我们表演了。(turn)_3没有人知道这个风俗是何时开始存在的。(existence)_4他讲英语如此清楚以至于总是能被理解。(so.that.)_5他让大家明白开这个会是必要的。(it)_课时作业(七).1.theory2.billion3.violent4.exist5harmful6.puzzled7.Unlike8.oxygen9globe10.atmosphere.1.D句意：城市改造将使得这里的人们有一个舒适的环境。it作形式宾语，真正的宾语为后面的不定式的复合结构。2B句意：今年这个节日过得很成功，不像前年过节时，雨下个不停。根据题干，此处需用介词，故排除C、D两项。unlike意为“不同；不像”，符合题意。like“相像的；类似的”。3D第一空为take turns to do sth.“轮流干某事”；第二空为It is ones turn to do sth.“轮到某人干某事”，故选D项。4B句意：在这部滑稽短剧中，主角说他的公鸡刚刚下了一枚蛋。lay eggs产卵，下蛋，lay的过去式、过去分词分别laid，laid；lie(躺)的过去式、过去分词为lay，lain；lie(说谎)的过去式、过去分词为lied，lied。由句意可知答案为B。5A句意：你最好停止酗酒，因为它会增加患血液疾病的风险。multiply增加；occupy占据；take拿；achieve取得。结合句意，A项最佳。6B句意：我们建议他们提供有效的预警系统来阻止很多灾难的发生。prevent.from doing.“阻止做”；keep.doing.“使一直做”；happen“发生”，无被动语态。故B项正确。7A句意：面临着令人困惑的局势，销售部经理看起来迷惑不解。第一空形容situation的特点，用puzzling；表示人困惑时，用puzzled。8B句意：看太多电视对孩子们的身心都有害。be harmful to“对有害”，为固定短语。peaceful“和平的；宁静的”；wonderful“极棒的”；careful“小心的；仔细的”。9A根据语意应该是风俗的存在，只有A项exist表示“存在”，appear表示“出现”，live表示“居住”，lie表示“坐落于，某处有某物”。10C句意：到目前为止进展顺利。因此，我们确信工程会准时完成。however然而；otherwise否则，不然的话；thus因此/而；besides而且。11Bgive birth to为固定搭配，意为“生产，生下”。仔细分析句子结构可知“_birth to twins last year”是定语，修饰the woman。woman与give之间是逻辑上的主谓关系，故排除C、D两项。A项表示未发生的动作，与last year不符，故只能选B。12B句意为“他们对那个国家进行了猛烈的空袭”。firm“坚固的”；violent“猛烈的”；painful“疼痛的”；huge“巨大的”。由句意可知，B项正确。13B句意为“如果我们现在动身，就能及时赶上去北京的第一班火车”。in time“及时”；at times“有时”；at a time“每次”；at one time“曾经，一度”。14C句意为“众所周知，衣、食、住、行是人类的基础”。fundamental“基本的，基础的”，符合句意。unlike“不同，不像”；gentle“温和的，温柔的”；genuine“真的，真诚的”。15D第一空后有many，应用so修饰；从句中不缺少主语、宾语等，因此该从句不是定语从句，而是结果状语从句，因此第二个空应选择that。.1.A由下文的on the other hand可知，此处应为on the one hand“一方面”，为固定搭配。2Badvise后不能直接跟不定式。根据句意此处需用被动语态。3C句意“建议人们给研究工作提供一种自由的氛围”。space和room表示“空间”时，均为不可数名词，其前不能使用不定冠词a。discussion“讨论”，不符合句意。4B根据on the other hand与前面构成的相反的关系，可知harmful符合句意。be harmful to意为“对有害”。5C这样，对政府来说是否限制科学研究和发展应该有个平衡。for此处意为“对于来说”。6A根据这句话中的balance可以推断出选A项。improve“改进”；block“封锁，阻碍，堵住”；puzzle“(使)迷惑，(使)为难”。7Cnow that意为“既然”，其引导的句子与后一句话成因果关系。for意为“由于”，也可引导表示原因的分句，但常放在主句的后面，且有逗号将其与主句隔开。8A既然科学研究是一项可预先做的工作。in advance“预先，事先”，固定短语。9B对政府甚至是公众来说很难确定一项研究是否是有价值的。根据句意可知选B项。10D但是科学研究不像其他事情，没有创造是行不通的。根据句意可知选D项。11B承前，众所周知，创造性是不应被限制的。creativity“创造”，为名词。create为动词，意为“创造”；creative为形容词，意为“有创造力的”；creator为表示人的名词，意为“创建者，创作者”。12A如果回顾过去，我们将发现许多深远的研究工作都来自自由地思考。look back“回想，记起”。look out“注意”；look into“调查”；look after“照顾”。13Ba good many和a great deal of都意为“很多”，前者接可数名词复数，后者接不可数名词。其他两个词组搭配不正确。14D由下文的“His raw idea.meaningless.”可知选D项。15B举爱因斯坦为例。take.for example“举为例”，为固定短语。16D他提出了相对论。come
