16、ppy.阅读理解(共20小题；每小题2分，满分40分)AParicutin(帕里库廷火山) was born in Mexico in February,1943.At that time，Paricutin was 500 feet high，and it is now over 9000 feet high.Today Paricutin is asleep.What is Paricutin？It was the first volcano (火山) in the world which was seen from its birth right up to the present da
17、y.On February 20,1943，a peasant and his wife set out to work in their corn fields from the Mexican village of Paricutin.They were surprised to find the earth warm under their feet.Suddenly they heard noise deep in the earth and a small hole appeared in their field.In the afternoon there was a sudden
18、 loud noise and stones were thrown high in the air.The peasants ran from the field and turned to watch.They saw the birth of a volcano. Large quantities of stone and lava broke out and a little hill began to form.By evening this hill was 100 feet high and hot ashes(灰烬) were falling on the village.At
19、 night the strong light of the hot lava lit up the countryside.The trees near the village were killed and the villagers had to leave their houses.When the village was destroyed，its name was given to the volcano.The news quickly reached Mexico City，far to the east.Many people came to watch the scene.
20、The volcano grew and grew for ten years and hundreds of square miles of forests were destroyed.Then Paricutin went to sleep.56What was destroyed in the growing up of the volcano?AThe little hill of stone. BThe villagers living close by.CThe forests and fields around Paricutin. DThe Mexican peasant a

22、BVolcanoes are always growing.CVolcanoes are active from time to time.DNew volcanoes are active for only ten years.59What does the sentence “Then Paricutin went to sleep” mean?AParicutin was tired. BParicutin hasnt slept for two days.CParicutin caused too much damage. DThe eruption of Paricutin stop
23、ped.BAn annoying problem for humans，who like to boast(夸耀) about all the distant planets and moons we have explored，is that weve never taken a good look right under our noses.The inside of the earth is relatively close，but how can we get there?The deepest oil well enters only six miles into the crust
24、 (地壳) (the center of the earth is about 4000 miles deeper)Russian scientists dug the deepest hole in Siberia，but bottomed out at about 7.5 miles below the surface.The Mohole project，a US.plan in the 1950s，called for drilling a hole 25 miles down to the boundary(分界线) between the hard rocks of the cru
25、st and the soft mantle (地幔)Sadly the project involved government supporting.It gets harder and harder to drill deep into the earth because rocks get softer and softer.Hard but easily broken at the surface，rocks become plastic at depth，and the pressure caused by the weight of the overlaying crustabou
26、t 52 800 pounds per square inch at a depth of ten miles，makes further drilling impossible. What little we know about the inside of the earth comes from indirect evidence，such as the analysis of earthquakes.So maybe its time for a thorough new method to explore the earths inside.Scientist David Steve
27、nson says we should forget about drilling holes.Instead，we should open a crack (裂缝)Stevenson suggests digging a crack about a half mile long，a yard wide，and a half mile deep but with an explosion on the scale of a nuclear bomb.Next，hed pour a few hundred thousand tons of molten (熔化的) iron into the c
28、rack，along with a robot.The iron，thicker than the surrounding crust，would move downward at about 16 feet per second，carrying the robot with it and opening the crack deeper and deeper.The iron mass would drop for about a week and 2000 miles to the outer edge of the earth core，the robot sending out da
29、ta to the surface.Stevenson compares his idea to space exploration.“Were going somewhere we havent been before，” he says.“In all possibility，there will be surprises.”This idea can probably be put in the drawer marked with Isnt Going To Happen.The robot would have to survive temperatures that would m
30、elt pretty much anything.But Stevensons idea may inspire a new look at an old problem.Great things can come from what seems like impossible ideas.60Going inside the earth is _ than going into space.Amore interesting Bmore possible Ceasier Dmore challenging61How deep have we gone into the earth until
31、 now?A6 miles. B4000 miles. C7.5 miles. D25 miles.62Which of the following is TRUE about David Stevensons idea?AIt is an inspiring but not practical idea now.BIt is a practical proposal that has come into use now.CIt is a good proposal that will soon be put into practice.DIt is a false theory that c

33、)and theatres，its shops and restaurants.The tourists do not，however，see Pompeiis people.They do not see them because Pompeii has no people.No one has lived in Pompeii for almost 2000 years.Once，Pompeii was a busy city of 22 000 people.It lay at the foot of Mount Vesuvius，a grasscovered volcano(火山)Mo
34、unt Vesuvius had not erupted(喷发)for centuries，so the people of Pompeii felt safe.But they were not.In August of AD 79，Mount Vesuvius erupted.The entire top of the mountain exploded，and a huge black cloud rose into the air.Soon stones and hot ash began to fall on Pompeii.When the eruption ended two d
35、ays later，Pompeii was buried under 20 feet of stones and ashes.Almost all of its people were dead.For centuries，Pompeii lay buried under stone and ash.Then，in the year 1861，an Italian scientist named Ginseppe began to uncover Pompeii.Slowly，carefully，Ginseppe and his men dug.The city looked almost t
36、he same as it had looked in AD 79.There were streets and fountains，houses and shops.There was a stadium with 20 000 seats.Perhaps the most important of all，there were everyday objects，which tell us a great deal about the people who lived in Pompeii.Many glasses and jars had some dark blue color in t

70、，作者要告诉我们一个有趣的故事，一个火山竟然从脚底下冒出来。答案：A58解析：从第二段第三句 “They were surprised to find the earth warm under their feet.Suddenly they heard noise deep in the earth and a small hole appeared in their field.”看出火山也许在人们没有预料到的地方冒出来。答案：A59解析：帕里库廷火山的“睡眠”意指“停止喷发岩浆了”。答案：D60解析：从第一段的第一、二句看出与探索太空相比较，地下面相对闭塞，要具有挑战性。答案：D61解析
71、：从第二段的“Russian scientists dug the deepest hole in Siberia，but bottomed out at about 7.5 miles below the surface.”看出，到目前为止，最深的井是7.5 miles，B项是到地心的数据，D项是计划要挖的深度。答案：C62解析：从最后一段的“But Stevensons idea may inspire a new look at an old problem.”一句看出Stevenson的观点令人惊讶，但是，当前实现不了。答案：A63解析：此题考查主题大意，从第二句可以看到此意，A项包括
72、B、C、D三项，但是选B、C、D中的任何一项都会否定A项。答案：A64解析： 这是一道细节推断题。原文没有直接说出参观者到Pompeii的目的。通读全文可知，Pompeii是一座被火山吞没的城市。由于火山突然喷发，人们来不及逃避，而保留了当时人们生活的遗迹。所以参观者来的目的是看一看Pompeiians当时是如何生活的。但由于一些考生只注意到短文第一段最后一句话 “No one has lived in Pompeii for almost 2000 years.”和后面提到的volcano一词，错误地选择了选项A。答案：D65解析：这是一道细节题。从第二段后两句话“Mount Vesuviu
73、s had not erupted for centuries，so the people of Pompeii felt safe.But they were not.”可以得出结论，几乎没有人想到火山会重新喷发。答案：C66解析：这是一道细节推断题。从第二、三段可知，Pompeii位于Mount Vesuvius山脚下，Mount Vesuvius是一座火山，但有多个世纪没有喷发了。人们以为它不会再喷发，但是，在公元79年8月，火山突然喷发，整个城市被埋葬在石头和灰尘下。由于火山突然喷发，人们在毫无思想准备的情况下被埋葬了，所以保留了当时全部的情景。答案：B67解析：这是一道推断题。从倒数
74、第二段所述参观者所看到2000年前Pomeiians生活的情景可以得出结论，他们当时的生活状况或多或少和现在的意大利人生活的状况相同。答案：A68解析：根据第三段第一句中“The institute cannot tell exactly when the next eruption will hayrpen”可知B项所述不正确。答案：B69解析：根据画线处lava flows 以及ash fall 可知画线处与它们属于同一类，可知B项所述都是来自火山的。pyroclastic“火成碎屑的”。答案：B70解析：根据最后一段“If you would like more information
75、about our services.please get in touch with our nearest office.”可知要得到更多的信息，请与最近的办公室联系。答案：C71解析：综合全文可知本文为某机构在宣传自己的服务，A、B、C选项是其中一部分，太片面了。答案：D72解析：从第一段的“Animals often seem to know in advance that an earthquake is coming”一句看出动物能够预测地震。答案：B73解析：第一段的“Before a Chinese quake in 1975 snakes awoke from their w
76、inter sleep early only to freeze to death in the cold air.Cows broke their halters(缰绳) and tried to escape.Chickens refused to enter their coops.”中提到了A、B、C三项的内容，没有提到D项的内容。答案：D74解析：从最后一段的“Many animals can see，hear，and smell things that people do not even notice.Some can detect tiny changes in air pre
77、ssure，gravity，or the magnetism (磁力) of Earth.This extra sense probably helps animals predict quakes.”看到一些动物能够预测地震是因为它们能够发现“tiny changes in air pressure，gravity，or the magnetism (磁力) of Earth.”因此选D项。答案：D75解析：从第二段的美洲狮和最后一段看出只是一些动物能够在地震前出现奇怪行为，但是，并没有确切地发现所有的动物怎样确切地知道什么时候地震。答案：C.76解析：thousands of 成千上万的，
78、表示具体的数字时，thousand用单数。答案：thousandthousands77解析：通篇用现在时态，指当前的事实。答案：was is78解析：like water像水一样，as作为。答案：aslike79解析：boiling正在沸腾的。答案：boiledboiling80解析：构成不定式try to do。答案：get前加to81解析：在肯定句中用also，不用either。答案：either also82答案：83解析：the earth指地球，earth泥土。答案：earth前加the84解析：push up冲上去。答案：downup85解析：此处是并列关系。答案：butand.参
79、考范文：A Predicted EarthquakeOn Feb.24th,1975，Chinese Earthquake Science Research predicted that there would be an earthquake in Haicheng，Liaoning.After the local people moved out of their houses，at 7：36，a strong earthquake of 7.3 scales did take place in Haicheng.As a result of the proper prediction，the loss of the lives and possessions were reduced.There were no more than 1300 deaths.This was the first successful prediction in the world.It was well known as the wonder of science.
