　　Eruptions of Mount Saint Helens

　　On March 27，the US Govemment scientists made a decision after they predicted the emption of Mount Saint Helens．They telephoned all state and local officials in the area and told them that a serious eruption was possible at any time,Roads were closed to every one except scientists and forest keepers struggled to keep curious visitors away from the mountain.

　　Shortly after noon on March 27，Mount Saint Helens erupted for the first time in 1 23 years．People living north of the mountain heard a loud boom that shook their windows，and airline pilots flying near the volcano soon afterwards described a thick black colunm of ash and steam shooting more than 2，100 meters into the sky．

　　Later,scientists found that the explosion had made a new crater(大坑)in the top of the mountain．not far from the old crater．The north side of the peak now had a huge bulge(凸出部分) where rock and ice had been pushed out by the eruption．

　　A second eruption shook the mountain on March 28．It，too，sent up a column of black ash high into the sky．By March 29，scientists flying over the mountain saw that a second crater

　　formed about 9 meters from the first one．Strange blue flames flickered(闪烁)inside the crater and sometimes jumped from one crater to the other．

　　By April the mountain had erupted several more times and the snow on the north slope of the peak was black with ash．Ash carried by the wind had fallen on towns as far as 240 kilometers

　　away from Mount Saint Helens．

　　During the first week of April，Mount Saint Helens gave scientists something new to worry about：harmonic tremors(震动)recorded by scientists showed a big eruption would happen．All during April and into May Mount Saint Helens continued to shudder(震动)and shoot out ash．By.April8, two craters had merged to from a vast hole nearly a half of a kilometer wide and 250 meters deep．

　　Scientists'main worry during this time was the growing bulge of rock and ice on．the north face of the mountain．By May 7 scientists feared the worst．Their warnings led Washington Governor to set up safety zones around the mounmin．The inner"red"zone was open to scientists only．The outer"blue"zone was open only to people who got special permits．But in spite of

　　these warnings，some people got past the road barriers and risked their lives trying to get close to the volcano．

　　Electromagnetic Energy

　　1．White light seems to be a combination of all colors．The energy that comes from a source of light is not limited to the kind of energy you can see．Heat is given off by a flame or an electric light．On a cloudy day it is possible to get a sunbam even though you feel coo1．Visible light and the kinds of energy that produce warmth and sunburn are examples of electromagnetic energy．

　　2．The sun is 93 million miles from the earth．Yet we can use energy from the sun because electromagnetic energy travels through space．

　　3．Many Other kinds of energy are also types of electromagnetic energy．Radio，television，and radar signals travel from transmitters to receivers as low-energy electromagnetic wavesl Infrared(红外线的)radiation is an electromagnetic wave．When it is absorbed by matter．heat is produced.Waves of infrared and visible light have more energy than waves of radio，television，or radar.Ultraviolet rays(紫外线)and X-rays are electromagnetic waves with even greater amounts of energy．Infrared radiation is used in cooking food and heating buildings．Sunlight and electric lights are part of our requirements for normal living．Ultraviolet radiation is useful in killilag certain disease organisms．X-rays and gamma rays have so much energy that they travel right through solid obieets．They can be used to detect and treat cancer．X-rays are used in industry to find hidden cracks in metal．and in medicine to reveal broken bones．

　　4．  Usually we use electricity to．generate electromagnetic energy．The source of most of our energy is the sun．Heat from the sun causes water to evadorate．When the water falls to the earth as rain．some of it is trapped behind dams and then used to operate electric generators．Other generators are powered by coal，but the energy stored in coal came from the sun，too．

　　5．Until recently,the source of the tremendous amount of energy given off by the sun was a puzzle．If the sun depended on chemical reactions．it would have used up all its energy long ago．Experiments with electromagnetic radiation led to the theory that mass can be converted into energy．About forty years after the theory was proposed，nuclear energy was hamessed(利用)by man.Chemical energy comes from electron(电子)rearrangement．Nuclear energy comes from a change in the nucleus of an atom．Compared with chemical reactions，nuclear reactions release millions of times more energy per pound of fuel．We now believe that the sun's energy comes from the nuclear reactions in which hydrogen is changed into helium (氦)．

　　6．  Nuclear energy is beginning to compete with coal as an economical source of power to generate electricity．It is also being used to operate engines in large ships．Scientists continue to seek new and better methods of obtaining and using energy.

　　下面有3篇短文，每篇短文后有5道题，每题后面有4个选项。请仔细阅读短文并根据短文回答其后面的问题，从4个选项中选择1个最佳答案涂在答题卡相应的位置上。

　　第一篇     Valuing Childhood

　　The value of childhood is easily blurred(变得模糊不清)in today's world．Consider some recent developments：The child．murderers in the Jonesboro,Ark．schoolyard shooting case were convicted and sentenced．Two boys，7 and 8,were charged in the murder of an 11-year-old girl in Chicago．

　　Children who commit horrible crimes appear to act of their own will．Yet，as legal proceedings in Jonesboro showed，the one boy who was able to address the court couldn't begin to explain his acts．though he tried to apologize．There may have been a motive-youthful jealousy(妒忌)and resentment．But a deeper question remains：Why did these boys and others in similar trouble apparently lack any inner,moral restraint?

　　That question echoes for the accused in Chicago．young as they are．They wanted the girl's bicycle,a selfish impulse common enough among kids．

　　Redemption(拯救)is a practical necessity．How can value be restored to young lives distorted by acts of violence?The boys in Jonesboro and in Chicago will be confined in institutions for a relatively short time．Despite horror at what was done，children are not-cannot be-dealt with as adults．not if a people wants to consider jtself civilized．That's why politicians'cries for adult treatment of youthful criminals ultimately miss the point．

　　But the moral void(真空)that invites violence has many sources．Family instability contributes：So does economic stress．That void．however,can be filled．The work starts wifh

　　parents，who have to ask themselves whether they're doing enough to give their children a firm sense of right and wrong．Are they really monitoring their activities and their developing processes of thought?

　　Schools．too,have a role in building character．So do youth organizations．So do law enfomement agencies，which can do more to inform the young about laws，their meaning，and

　　their observance(遵守)．

　　The goal．ultimately,is to allow all children a normal passage from childhood to adulthood (成年)，so that tragic gaps in moral judgement are less likely to occur. The relative few who fill such gaps with acts of violence hint at many others who don't go that far,but who 1ack the moral foundations childhood should provide-and which progressive human society relies on．

　　3l The two boys in Chicago were

　　A  shot．

　　B  murdered．

　　C  accused．

　　D  sentenced．

　　32 The boys in Jonesboro and Chicago apparently lacked a sense of

　　A  right and wrong．

　　B discipline．

　　C  shame．

　　D  safety．

　　33 According to politicians，when children commit crimes，they should be treated in the same way as

　　A  murderers.

　　B  criminals．

　　C  victims．

　　D  adults．

　　34 Which of the following does the writer cite as a source of moral void?

　　A  Official corruption．

　　B  Social injustice．

　　C  Family instability．

　　D  Racial discrimination．

　　35 Which of the statements is NOT true according to this passage?

　　A  Parents should strengthen moral instruction．

　　B  Schools should help create a moral sense in children．

　　C Law enforcement agencies should do more to help children understand laws?

　　D  Youth organizations play no role in building character．
