In places it is more than 370 metres deeply. There has been reports of monsters in Lake Tianchi since the beginning of the last century. Some photo have been taken but they are not clear because of it was too far away. Many people thought the monster may be a distant cousin of the Loch Ness monster in Scotland. They also think that there might be similar creatures in other lakes around world. Scientists, therefore, are skeptical. They say that the low-temperature lake is unlikely to being able to support so large living creatures.二、阅读理解。Unlike modern animal scientists, dinosaur scientists cannot sit on a hillside and use telescopes to watch dinosaurs in order to know how they lived and whether they were good parents. Instead, they have to search hard for information from dinosaurs fossils(恐龙化石) because dinosaurs died out millions of years ago.Its very difficult for the scientists to reach an agreement because different results can be got from the same fossils. Many fossils of the same kind of dinosaurs have been dug out from one place. They might have formed when an entire group of dinosaurs got stuck (陷入) all at once, or they might have been the result of dinosaurs getting stuck one after another over a course of a few centuries. Thus we can say that dinosaurs might have in the first case lived in big groups and in the second lived alone.Though there are two different results, dinosaur scientists now generally agree that at least some kinds of dinosaurs lived in big groups. “Thats pretty much settled at this point,” says Paul Sereno. A kind of dinosaurs called Sauropods left behind tracks in the western United States that appear to run north and south, suggesting that they even moved long distances together.As to whether dinosaurs cared for their young, dinosaur scientists have turned to the closest living relatives of dinosaursbirds and crocodilesfor possible models. Birds give a lot of care to their young, while crocodiles just help their young to the water. The discovered fossils of dinosaurs sitting on their eggs and staying with their young suggest the parents were taking care of their babies, but we still cannot say that all dinosaurs did the same.There is still a long way to go before the above questions could be answered. Dinosaur scientists will have to find more proof to reach an agreement.1. Dinosaur scientists can get information directly by _.A. studying dinosaur fossilsB. examining modern animalsC. watching dinosaursD. using telescopes2. What is pretty much settled according to Paul Sereno?A. Half of the dinosaurs lived alone.B. Most dinosaurs moved long distances.C. Many dinosaurs settled in the north.D. Some dinosaurs lived in big groups.3. Dinosaur scientists can probably know whether dinosaurs were good parents by _.A. watching many kinds of animalsB. studying dinosaurs living relativesC. following the tracks left behindD. working on dug-out dinosaur eggs三、完形填空。He has been called the “missing link”.

But the only things people have ever found were 10 footprints. Most believe the footprints are nothing more than 11 animal tracks, which had been made 12 as they melted(融化) and refroze in the snow. 13, in 1964, a Russian scientist said that the Abominable Snowman was 14 and was a remaining link with the prehistoric humans.

A【解析】从第一段最后一句“Instead, they have to search hard for information from dinosaurs fossils(恐龙化石) because dinosaurs died out millions of years ago.”可以看出，是通过研究找到信息。2. D【解析】从第三段可以看出：虽然有两种不同的结论,研究恐龙的科学家们现在一般都同意至少有某些种类的恐龙生活在一个大的团体当中，这一点是确信无疑的。3. B【解析】从第四段的开头“As to whether dinosaurs cared for their young, dinosaur scientists have turned to the closest living relatives of dinosaursbirds and crocodilesfor possible models.”可知，科学家们转向恐龙活着的近亲鸟类和鳄鱼来寻求恐龙是否关心下一代这个问题的答案。三、完形填空。1-5 BDCAB 6-10 DDCAB 11-15 CBDBC 16-20 BCADA1. B【解析】后文叙述的是关于Yeti的传说故事。2. D【解析】从20世纪20年代开始被发现，至今应有许多年了。3. C【解析】当地人称这种生物为“Yeti”，肯定是知道它以及关于它的事。hear from“收到的来信，得到信息”；care for“照顾”；know of“知道,了解”；read about“读到”。4. A【解析】 “抓住”比“知道”更进
