综合写作 五星级题目 1 阅读材料讲wetland 里面鬼火will-o-the-wisp 的原因，三个： 1 埋在里面的有机体释放出可燃的气体。 2 是一种electric spark。 3 一种能发光的蘑菇附着在鸟身上听力部分反驳： 1 可燃气体是不动的，但是人们看见的鬼火是move around。 2 electric spark 是在wetland 下面的rock 中生成的，不会跑到上面来。 3 这种蘑菇的发光物质在体内，要broken into pieces 才有用，但是这种物质不sticky，所以 会从鸟身上掉下来 2 侏罗纪时代的生物灭绝了，文章说可能是因为彗星撞地球，依据就是一些发现的古老的生 物还是什么的碎片，然后它们可以 dating back to XXX 年以前，并且在中国，日本还有某个国家 都有发现，然后发现某个沟壑还是海峡有可能就是那个坑 speech 说第一那些碎片的化学物质没 有因为地壳运动受热而改变，所以时间应该很短，应该没有 250-millionold 这么老。第二碎片只 在那三个国家被发现过，如果冲击力那么强的话，那碎片应该是散落在全世界的。 第三，类似那个坑的坑到处都是，火山运动也会是造成沟壑的原因，该是地球内部地质活动形成 的。 The reading passage presents three pieces of evidence to support the theory that the Permian– Triassic mass extinction was triggered by a meteorite impacting Earth. However, the lecturer rejects this theory by pointing out its weaknesses. The first evidence is the recent discovery of meteorite fragments containing mineral grains which dated to 250 million years ago, the same time when the extinction occurred. However, the lecturer rejects this theory as unconvincing, arguing that any substance would be transformed completely after 250 million years of gradual chemical process, so the minerals now preserved in the fragments must have been formed quite recently. The second evidence is the scattered meteorite fragments in China, India and [], indicating the magnitude of a disastrous meteorite impact that could wipe out almost the entire species on Earth. Yet according to the lecture, the fact that the fragments were only found in three countries, and not in the rest of the world such as Europe, was actually proof that the meteorite collision was not strong enough to cause such a massive extinction. The third evidence is a large crater found off the coast of Australia. Its size matches that of a meteorite, indicating that it was an impact site for a meteorite collision. Nevertheless, the lecturer proposes a different theory. He explains that this crater may have been caused by Earth’s internal force
