1、河北省承德市第一中学2020-2021学年高二英语下学期第三次周测试题本试卷满分100分，时间45分钟 I阅读理解(每题2.5分，总分27.5分)AWhales，like dolphins，belong to a group of mammals called “cetaceans”This name comes from a Latin word meaning “large sea animals”There are at least seventy-five kinds of cetaceans. Scientists divide the various kinds into two

2、major groupsbaleen whales，which do not have teeth，and toothed whales，which have teeth. Whales have the same basic shape as fish，but they differ from fish in many ways. The most noticeable difference is the tail. Fish have vertical tail fins(鳍)，but whales have horizontal tail fins. Fish breathe by me

3、ans of gills(鳃)，while whales have lungs and must come to the surface to breathe. But they can hold their breath for long periods.Like other mammals，whales give birth to live young and feed them with milk produced by the mothers body. Most fish，however，lay eggs and do not feed their young. Whales are

4、 also warm-bloodedthat is，their body temperature remains about the same all the time. Almost all fish are cold-blooded. Their body temperature changes with changes in the temperature of the water.Whales have a highly developed brain and they are highly advanced life forms. They sing to their young，e

5、ngage in complex family relationships，and their communication skills are fine.In December 2005，a whale，after being rescued from fishing nets，didnt just swim back to deep water. It hung around and touched each of the divers with its mouth. “Knowing that it was free，it stopped about a foot away from m

6、e，pushed me around a little bit and had some fun，” said dive master James Moskito.He thought it was “one of the most fantastic moments” of his life.1According to Paragraph 1，which of the following shows the correct relationship?AMammals are a type of cetacean.

8、ack to the sea after it was saved?AIt lost its way in the sea. BIt was seriously wounded.CIt was frightened by the divers. DIt wanted to thank the divers.BSome years ago，Michel Andre found himself staring at the body of a dead whale on a beach in the Canary Islands. It was obvious that the animal ha

9、d been struck violently by a shipbut why? Only later，after surveying the whales which lived in the area and measuring the increase of sound pollution from ships did it become clear that there was a link.The whales had become desensitised to the noise of approaching boats and were being struck by the

10、m，often seriously. “We never thought that this could be something that could kill，” recalls Andre，who is the director of the Laboratory of Applied Bioacoustics at the Technical University of Catalonia，Barcelona.Andre has spent 20 years developing an advanced system to better understand why incidents

11、 like this happen. His underwater microphones have exposed a world of deafening sound and animal communication never observed with such clarity(清晰) before.It was not an easy task. Sound waves dont travel through water in the uniform，predictable way they do through the air. Instead，the temperature，sa

12、linity(盐度) and，flow of water have great effects on their path.What can be done? One solution is to change shipping routes to courses where ships are statistically less likely to meet animals. Its also possible to slow ships down to 18km/h or less，which is less likely to seriously injure a whale.As f

13、or dealing with the root cause of the problem，the UNs International Maritime Organisation has already published guidelines on how to quieten ships，but it will be a while before the effects of such changes might be observed.“The ocean is not our world，” comments Andre. But it is ours to look after. A

14、nd thanks to his work，we can better understand the effects of subsea sound pollution.4What does the underlined word “desensitised” in Paragraph 2 mean?AStubborn. BFlexible. CDull.

DUncaring.7What is the text mainly about?AA great expert. BNoise in the sea.CAnimals in the sea. DSea explora

16、tion technology. CCalifornia has lost half its big trees since the 1930s, according to a study to be published Tuesday and climate change seems to be a major factor(因素).The number of trees larger than two feet across has declined by 50 percent on more than 46, 000 square miles of California forests,

17、 the new study finds. No area was spared or unaffected, from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles. In the Sierra high country, the number of big trees has fallen by more than 55 percent; in parts of southern California the decline was nearly 7

18、5 percent.Many factors contributed to the decline, said Patrick Mclntyre, an ecologist who was the lead author of the study. Woodcutters targeted big trees. Housing development pushed into the woods. Aggressive wildfire control has left California forests crowded with small trees that compete with b

19、ig trees for resources(资源).But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010, Mclntyre and his colleagues documented a widespread death of big trees that was evident even in wildlands protected from woodcutting or development.The loss o

20、f big trees was greatest in areas where trees had suffered the greatest water shortage. The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed, taking into account such things as rainfall, air temperatu

21、re, dampness of soil, and the timing of snowmelt(融雪).Since the 1930s, Mclntyre said, the biggest factors driving up water stress in the state have been rising temperatures, which cause trees to lose more water to the air, and earlier snowmelt, which reduces the water supply available to trees during

22、 the dry season.8. What is the second paragraph mainly about?A. The seriousness of big-tree loss in California.B. The increasing variety of California big trees.C. The distribution of big trees in California forests.D. The influence of farming on big trees in California.9. Which of the following is

23、well-intentioned but may be bad for big trees?A. Ecological studies of forests.B. Banning woodcutting.C. Limiting housing development.D. Fire control measures.10. What is a major cause of the water shortage according to Mclntyre?A. Inadequate snowmelt.B. A longer dry season.C. A warmer climate.D. Da

24、mpness of the air.11. What can be a suitable title for the text?A. Californias Forests: Where Have All the Big Trees Gone?B. Cutting of Big Trees to Be Prohibited in California SoonC. Why Are the Big Trees Important to California Forests?D. Patrick Mclntyre: Grow More Big Trees in California.七选五（共5小
