题目内容
19．The twentieth century saw greater changes than any century before．Changes for the better，changes for the worse，changes that brought a lot of benefits to human beings，changes that put man in danger．Many things caused the changes，but，in my opinion，the most important was the progress in science．Scientific research in physics and biology has vastly broadened our views．It has given us a deeper knowledge of the structure of matter and of the universe．It has brought us a better understanding of the nature of life and of its continuous development．Technology in the application of science has made big advances that have benefited us in nearly every part of life．
The continuation of such activities in the twenty-first century will result in even greater advantages to human beings； in pure science-a wider and deeper knowledge in all fields of learning； in applied science-a more reasonable sharing of material benefits，and better protection of the environment．
Sadly，however，there is another side to the picture．The creativity of science has been employed in doing damage to mankind．The application of science and technology to the development and production of weapons of mass destruction has created a real danger to the continued existence of the human race on this planet．We have seen this happen in the case of nuclear weapons．Although their actual use has so far occurred only in the Second World War，the number of nuclear weapons that were produced and made ready for use was so large that if the weapons had actually been used，the result could have been the ruin of the human race，as well as of many kinds of animals．
William Shakespeare said，"The web of our life is of a mingled yarn，good and ill together．"
The above brief review the application of only one part of human activities-science seems to prove what Shakespeare said．But does it have to be so？Must the ill always go together with the good？Are we biologically programmed for war？
21．Which of the following best shows the structure of the passage？A
（①=Paragraph 1，②=Paragraph 2，③=Paragraph 3，④=Paragraph 4，⑤=Paragraph 5）
22．From the fourth paragraph，we can infer thatD．
A．a great many nuclear weapons were actually used for war
B．a large number of nuclear weapons should have been used for war
C．the author is doubtful about the ruin of human beings by nuclear war
D．the author is anxious about the huge number of nuclear weapons on the earth
23．What do you think the author is most likely to suggest if he continues to write？D
A．Further application of science to war．
B．More reading of William Shakespeare．
C．Proper use of science in the new century．
D．Effective ways to separate the good from the ill．
分析 这是一篇议论文，点评了科技发展对人类社会的影响，有好有坏，也告诉人们应该怎样做才能保卫好地球．
解答 21-23 ADD
21．A 分析文章结构题．第一段总起，第五段总结，第二、三两段讲好的一方面，第四节讲坏的一方面，所以选A最佳．
22．D 推理题．从第四节，We have seen this happen in thecase of nuclear weapons．Although their actual use has so far occurred only inthe Second World War，…可以看出作者认为大量核武器的生产和准备投入使用将会给人类和地球上很多动物带来灭顶之灾，作者对此感到担忧．故选D．
23．D 推理题．根据文章最后一段Must the ill always go together with the good？Are we biologically programmed for war？可知科技发展有好有坏，是不是好坏并存，我们出生的时候是不是为打仗做准备的，所以作者接下来讲述的是如何区分好坏，故选D．
点评 一、速读全文，了解大意知主题．
阅读能力一般指阅读速度和理解能力两个方面．阅读速度是阅读最基本的能力．考生必须在十分有限的时间内运用略读、扫读、跳读等技巧快速阅读，搜寻关键词、主题句，捕捉时空、顺序、情节、人物、观点，并且理清文章脉络，把握语篇实质．
二、看题干，带着问题读文章．
首先要掌握问题的类型，客观信息题可以从文章中直接找到答案；而主观判断题考查的是对文章的感情基调等，这类题必须经过对作者的态度、意图以及对整篇文章进行深一层的推理等．其次，了解试题题干以及各个选项所包含的信息，然后有针对性地对文章进行扫读，对有关信息进行快速定位．此法加强了阅读的针对性，提高了做题的准确率．
三、逻辑推理，做好深层理解题．
在实际阅读中，有时作者并未把意图说出来，阅读者要根据字面意思，通过语篇逻辑关系，研究细节的暗示，推敲作者的态度，理解文章的寓义．要求读者对文字的表面信息进行分析、挖掘和逻辑推理，不能就事论事，以偏概全．推理题在提问中常用的词有：infer，imply，suggest，indicate等．
四、猜词悟义，扫除阅读拦路虎．
猜词是应用英语的重要能力．它不但需要准确无误地理解上下文，而且要有较大的泛读量，掌握或认识较多的课外词汇．我们要学会"顺藤摸瓜"，通过构词，语法，定义，同位，对比，因果，常识，上下文等线索确定词义．
