section grammar.阅读理解afor 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(民间传说)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 wellknown 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 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 1961，mrs.stoudt and her sister were walking with their children along a strait in washington, dc.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 snakelike 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.stoudts 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 7580 feet long.they described it as a tadpolelike(像蝌蚪的)creature with a snakelike head.they took pictures of the creature before it swam off.【语篇解读】数个世纪以来，有许多关于人们看到海怪的故事。这些故事经常被认为是民间传说，但大量的目击和现代科技的应用正在改变这种态度，使我们惊奇于这些故事可能是真的。1what does the underlined word “cases” in paragraph 2 most probably mean? aboxes.bexamples.cexplanations.dcreatures.解析：选b词义猜测题。文章第二、三、四段给出了三个目击实例，故cases意为“实例”。2which of the following statements about the 1848 sea monster is not true? ait was about sixty feet long.bit kept its head above the water when it swam.cits whole body was dark brown.dit was found in the atlantic ocean.解析：选c细节理解题。根据第二段中的“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.”可知c项符合题意。3it can be inferred from the passage that_athe 1848 sea monster swam faster than the 1961 and the 1964 sea monstersbthe three sea monsters mentioned in the passage each had a snakelike headcthe 1964 sea monster was longer than the 1848 sea monsterdrobert serrec went to australia in order to see a sea monster解析：选c细节理解题。根据第二段中的“about 60 feet long”和第四段中的“about 7580 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。4the writers purpose of writing the passage is_ato show people the danger of traveling by seabto tell us that sea monster stories might be truecto explain why people are afraid of sea monstersdto tell people where they can find sea monsters解析：选b细节理解题。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。bunlike 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.【语篇解读】研究恐龙的科学家通过研究恐龙化石来得到一些关于恐龙的信息。但对于同一个化石却有不同的研究结果。在研究恐龙是否能照看好幼崽方面，科学家们研究了恐龙的近亲鸟类和鳄鱼，但没能完全解答这个问题。5dinosaur scientists can get information directly by_.astudying dinosaur fossilsbexamining modern animalscwatching dinosaursdusing telescopes解析：选a细节理解题。根据第一段中的“they have to search hard for information from dinosaurs fossils(恐龙化石)”可知，研究恐龙的科学家通过研究恐龙化石来得到一些信息，故a项正确。6what is pretty much settled according to paul sereno? ahalf of the dinosaurs lived alone.bmost dinosaurs moved long distances.cmany dinosaurs settled in the north.dsome dinosaurs lived in big groups.解析：选d细节理解题。根据第三段中的“dinosaur scientists now generally agree that at least some kinds of dinosaurs lived in big groups”可知，paul sereno说科学家们都认为至少某些种类的恐龙群居，故d项正确。7dinosaur scientists can probably know whether dinosaurs were good parents by_awatching many kinds of animalsbstudying dinosaurs living relativescfollowing the tracks left behinddworking on dugout dinosaur eggs解析：选b细节理解题。根据第四段中的“dinosaur scientists have turned to the closest living relatives of dinosaursbirds and crocodilesfor possible models”可知，科学家们通过研究现存的恐龙的近亲鸟类和鳄鱼来判断恐龙是否能照看好它们的幼崽，故b项正确。8which of the following is true according to the 4th paragraph? abirds hardly pay attention to their young.bbaby crocodiles can look after themselves well.csome dinosaurs took care of their young.dbirds and crocodiles take good care of their young.解析：选c细节理解题。根据第四段可知，鸟类可以很好地照顾幼鸟，而鳄鱼只是帮助幼崽进入水里，并没有很好地照顾幼崽。化石表明一些恐龙照顾幼崽，但并不能证明所有的恐龙都是如此，因此c项符合题意。.短文改错dear jim，i am so exciting that you will come to china.i will free from december 18 and will have a plenty of time to be together with you.ill meet you at the airport and then you will take bus no.8 for my home.you worry about the weather here in your email.in fact，the weather here is quite different from it in your city.it isnt very cold，but you neednt bring many clothes with you.during your stay here，ill take you to some places of interests and you can taste some local snacks.i am sure we will have greatly fun together.looking forward to meeting you soon.john答案：dear jim，i am so that you will come to china.i will free from december 18 and will have plenty of time to be together with you.ill meet you at the airport a
