9、 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 creatures 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

13、例”。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.答案C解析细节理解题。根据第二段中的“in the Atlantic Ocean,seven men reported that they saw

14、a creature about 60 feet long.The creatures 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.”可知C项符合题意。3.It can be inferred from the passage that .A.the 1848 sea monster swam faster than the 1961 and

15、 the 1964 sea monstersB.the three sea monsters mentioned in the passage each had a snake-like headC.the 1964 sea monster was longer than the 1848 sea monsterD.Robert Serrec went to Australia in order to see a sea monster答案C解析细节理解题。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18

16、48年的海怪更长,所以C项正确。4.The writers purpose of writing the passage is .A.to show people the danger of travelling by seaB.to tell us that sea monster stories might be trueC.to explain why people are afraid of sea monstersD.to tell people where they can find sea monsters答案B解析目的意图题。根据文章第一段中的“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.”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,故B项正确。
