麻烦慧雯老师解答一下，老师您好，我这篇完全崩了，就对了一个，下面是我扫读的思路，因为我扫读比较慢（这种一般两分半到四分钟），麻烦老师看看有没有问题A meteor stream is composed of dust particles，These particles follow the same orbit as the parent comet, but they slowly gain on or fall behind.(观点)Astronomers have hypothesized that a meteor stream should broaden with time as （后面看不懂了，跳了）. A recent computer-modeling experiment tested this hypothesis. The researcher found, as expected, 验证了.

麻烦慧雯老师解答一下，老师您好，读这篇文章的时候没有明白第一段假设和观点之间的关系，我当时以为是 Astronomers（会变宽）和传统观点（中心集中）是两个相反观点，我也不知道为什么相反哈哈，就稀里糊涂往下做了，所以这道题选了相反观点的CIt can be inferred from the passage that which of the following would most probably be observed during the Earth's passage through a meteor stream if the conventional theories mentioned in the highlighted text were correct? A.Meteor activity would gradually increase to a single, intense peak, and then gradually decline. B.Meteor activity would be steady throughout the period of the meteor shower. C.Meteor activity would rise to a peak at the beginning and at the end of the meteor shower. D.Random bursts of very high meteor activity would be interspersed with periods of very activity. E.In years in which the Earth passed through only the outer areas of a meteor stream, meteor activity would be absent. The passage suggests that which of the following is a prediction concerning meteor streams that can be derived from both the conventional theories mentioned in the highlighted text and the new computer derived theory?这道题完全不知道该怎么定位，蒙了一个 Which of the following is an assumption underlying the last sentence of the passage? （这个题我是直接定位最后一句，因为也不太明白文章最后一段的关系，就往前看了点，大概明白就是距离时间速度之类的推出了时间，所以盲选了A ） A.In each of the years between 1970 and 1979, the Earth took exactly 19 hours to cross the Geminid meteor stream. B.The comet associated with the Geminid meteor stream has totally disintegrated. C.The Geminid meteor stream should continue to exist for at least 5,000 years. D.The Geminid meteor stream has not broadened as rapidly as the conventional theories would have predicted. E.The computer—model Geminid meteor stream provides an accurate representation of the development of the actual Geminid stream. 问题比较多麻烦您啦，这篇真的太绝望了，怎么破呀，我就对了第一题。。。谢谢老师~
