Lake Tianchi is the highest volcanic lake in the world, cover an area of about ten square kilometres. 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.

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.
It’s 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. “That’s 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 dinosaurs—birds and crocodiles—for 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 fossils
B. examining modern animals
C. watching dinosaurs
D. using telescopes
2. 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 animals
B. studying dinosaurs’ living relatives
C. following the tracks left behind
D. working on dug-out dinosaur eggs

三、阅读理解。
For centuries, men at sea have told stories about their experiences of seeing sea monsters like sea snakes and big whales. These stories are often considered as folk tales rather than real experiences. However, the large number of sightings and the use of modern technology are changing this attitude, making us wonder if those men were telling real experiences.
The following are some of the most well-known cases about sea monsters living in the oceans. On August 6, 1848, in the Atlantic Ocean, seven men reported that they saw a creature about 60 feet long. The creature’s body was dark brown in color except for its white throat area. The creature was swimming at a speed of 15 miles per hour with its head above the water.
In 1961, Mrs. Stoudt and her sister were walking with their children along a strait in Washington D．C. when they saw something like a tree branch in the water. As the object moved closer to them, they saw a creature, which had a snake-like head and 3 humps(峰). They said it looked like some sort of dinosaur. Then it moved even closer to them. Its frightening look made one of Mrs. Stoudt’s children cry.
On December 12, 1964, French photographer Robert Serrec was having a holiday in Queensland, Australia. He was out off the coast in small boats with his family and friends. Suddenly, they noticed a creature, about 75－80 feet long. They described it as a tadpole-like(像蝌蚪的) creature with a snake-like head. They took pictures of the creature before it swam off.
1. What does the underlined word “cases” in Paragraph 2 most probably mean?
A．boxes B．examples C．explanations D．creatures
2. Which of the following statements about the 1848 sea monster is NOT true?
A．It was about sixty feet long.
B．It kept its head above the water when it swam.
C．Its whole body was dark brown.
D．It was found in the Atlantic Ocean.
3. It can be inferred from the passage that ________．
A．the 1848 sea monster swam faster than the 1961 and the 1964 sea monsters
B．the three sea monsters mentioned in the passage each had a snake-like head
C．the 1964 sea monster was longer than the 1848 sea monster
D．Robert Serrec went to Australia in order to see a sea monster
4. The writer’s purpose of writing the passage is ________．
A．to show people the danger of traveling by sea
B．to tell people where they can find sea monsters
C．to explain why people are afraid of sea monsters
D．to tell us that sea monster stories might be true
答案与解析
一、完成句子。
1. mysterious 2. generosity 3. existence 4. attacked 5. to arrive
6. to 7. about 8. indicating 9. covering 10. disappeared
二、翻译。
1. The girl claimed to have seen a monster near the lake.
2. Many species/kinds of animals have already died out.
3. Due to the terrible weather, the match was cancelled.
4. He went to big cities, trying to make a fortune.
5. Be positive about your future and live a happy life.
三、阅读理解。
1-4 BCCD
1. B【解析】文章第二、三、四段给出了三个目击实例，故cases意为“实例”。
2. C【解析】根据第二段The creature’s body was dark brown in color except for its white throat area.可知不是整个身体是深棕色。
3. C【解析】根据第二段“about 60 feet long”和第四段中“about 75－80 feet long”可知1964年目击的海怪比1848年的海怪更长，所以C项正确。
4. D【解析】根据文章第一段However, the large number of sightings and the use of modern technology are changing this attitude, making us wonder if those men were telling real experiences.然而，大量的看见以及现代技术的使用在改变这一态度，使我们呢想知道那些人是否在讲述真实的经历。由此可知作者写这篇文章的目的是告诉读者那些关于海怪的故事可能是真的。
