GRE 阅读讲义DAY3
Day03知识点：观点点评与新旧观点辨析讲解经典例题Passage 109 （观点点评/ 难度-难/短篇文章）According to Hill and Spicer, the term “nation-state” is a misnomer, since the ideal model of a monolingual, culturally homogeneous state has never existed, not even among Europeans, who invented the nation-state concept and introduced it to the rest of the world. Modern European states, they argue, emerged after the Renaissance through the rise of nations (i.e., specific ethnic groups) to positions of political and economic dominance over a number of other ethnic groups within the bounded political territories. The term “nation-state”, Hill and Spicer argue, obscures the internal cultural and linguistic diversity of states that could more accurately be called “conquest states.” The resurgence of multiple ethnic groups within a single state, Hill says, is not “potentially threating to the sovereign jurisdiction of the state,” as Urban and Sherzer suggest; rather, the assertion of cultural differences threatens to reveal ethnocentric beliefs and practices upon which conquest states were historically founded and thus to open up the possibility for a “nations-state” in which conquered ethnic groups enjoy equal rights with the conquering ethnic group but do not face the threat of persecution or cultural assimilation into the dominant ethnic group.1. The primary purpose of the passage is toA. discuss issues relating to a form of political organization by raising doubts about the terminology used to refer to itB. trace changes in a form of political organization by examining the evolution of theC. justify the continued use of an established term for an evolving form of political organizationD. question the accuracy of a new term for a form of political organizationE. compare two terms for a form of political organizationDay03观点点评与新旧观点练习与讲解Passage 7 观点点评/文学评论/ 难Among many historians a belief persists that Cotton Mather’s biographies of some of the settlers of the Massachusetts Bay Colony (published 1702) are exercises in hagiography, endowing their subjects with saintly piety at the expense of historical accuracy. Yet modern studies have profited both from the breadth of information that Mather provides in, for example, his discussions of colonial medicineand from his critical observations of such leading figures as Governor John Winthrop. Mather’s wry humoras demonstrated by his detailed descriptions of events such as Winthrop’s efforts to prevent wood-stealingis overlooked by those charging Mather with presenting his subjects as extremely pious. The charge also obscures Mather’s concern with the settler’s material, not just spiritual, prosperity. Further, this pejorative view underrates the biographies value as chronicles: Mather amassed all sorts of published and unpublished documents as sources, and his selection of key events shows a marked sensitivity to the nature of the colony’s development.1. The primary purpose of the passage is toA. argue against a theory universally accepted by historical researchersB. call attention to an unusual approach to documenting a historical eraC. summarize research on a specific historical figureD. counter a particular view about the work of a biographerE. point out subtle differences among controversial historical reportsPassage 142 观点论证／自然科学地质／难Many theorists now doubt that heat loss from Earth’s core and radioactive decay are sufficient by themselves to produce all the energy driving the tectonic plates whose movements have helped shaped Earth’s surface. This leaves a loose end in current geological theory. Herbert Shaw argues that because scientists have underestimated the input of substantial amounts of energy from extraterrestrial impactors (asteroids and comets striking Earth), they have difficulty accounting for the difference between the quantity of energy produced from sources intrinsic to Earth and that involved in plate tectonics. Whereas most geologists have treated the addition of energy through the bombardment of Earth’s surface by such impactors as a process separate and independent from the movement of Earth’s tectonic plates, Shaw asserts that these processes are indivisible. Shaw’s revolutionary “open-system” view recognizes a continuum between terrestrial and extraterrestrial dynamics, whereas modern plate tectonic theory, like the classical geology developed during the nineteenth century, is founded on the view that Earth’s geological features have changed through gradual, regular processes intrinsic to Earth, without reference to unique catastrophic events. Classical geology borrowed a decisive, if unspoken, premise from Newton—the independence of Earth’s processes from any astronomical context.1. The author’s primary purpose is toA. identify the influences informing a particular geological theory about the processes that have shaped Earth’s surfaceB. identify differences between two views of the extraterrestrial impactors and argue that the phenomenon has influenced the development of plate tectonic theoryC. argue that an explanation is based on a dubious evidence and propose an alternative explanationD. discuss an explanation and place that explanation under theoretical contextE. suggest that apparent discrepancy poses a serious problem for a particular theory that many have believed。

Monique had had a history with horses and with young people. John had worked with children in trouble.Because of Monique's difficult childhood, she knew that horses could bring a hand.

And many say it changed their lives!One said, “They take you in with a smile and an open heart.”Another called it “a safe place of help and hope”．“I don't know where I'd be without the help of the horses，”said one boy.And finally someone mentioned, “Who_would_have_known_a_horse_could_teach_so_much！”()31.

1．动态规划：导弹拦截NOIP1999(提高组) 第一题【问题描述】某国为了防御敌国的导弹袭击，发展出一种导弹拦截系统。
但是这种导弹拦截系统有一个缺陷：虽然它的第一发炮弹能够到达任意的高度，但是以后每一发炮弹都不能高于前一发的高度。
某天，雷达捕捉到敌国的导弹来袭。
由于该系统还在试用阶段，所以只有一套系统，因此有可能不能拦截所有的导弹。
输入导弹依次飞来的高度（雷达给出的高度数据是不大于30000的正整数），计算这套系统最多能拦截多少导弹，如果要拦截所有导弹最少要配备多少套这种导弹拦截系统。
【输入文件】missile.in单独一行列出导弹依次飞来的高度【输出文件】missile.out两行，分别是最多能拦截的导弹数，要拦截所有导弹最少要配备的系统数【输入样例】389 207 155 300 299 170 158 65【输出样例】622．合唱队型NOIP2004(提高组) 第一题N位同学站成一排，音乐老师要请其中的(N-K)位同学出列，使得剩下的K位同学排成合唱队形。
合唱队形是指这样的一种队形：设K位同学从左到右依次编号为1，2…，K，他们的身高分别为T1，T2，…，TK，则他们的身高满足T1<...<Ti>Ti+1>…>TK(1<=i<=K)。
你的任务是，已知所有N位同学的身高，计算最少需要几位同学出列，可以使得剩下的同学排成合唱队形。
【输入文件】输入文件chorus.in的第一行是一个整数N(2<=N<=100)，表示同学的总数。
第一行有n个整数，用空格分隔，第i个整数Ti(130<=Ti<=230)是第i位同学的身高(厘米)。
【输出文件】输出文件chorus.out包括一行，这一行只包含一个整数，就是最少需要几位同学出列。

10天搞定大学英语四级核心词汇Day3
10天搞定大学英语四级核心词汇：Day3大家在前两天的学习中，一定有了较大的进步，也会对词的前后缀也有了很好的感性认识，那让我们来系统地学习一下词的构词法，特别要注意一下词的前后缀，将这件背单词的利器拿到手！同时，为了更好的帮助大家理解前后缀我们特意设置了前后缀卡片，建议大家将其撕下，在背单词时随时对照。
大家都知道，工欲善其事，必先利其器，我们背单词的利器就是构词法知识。
同时，在四级考试大纲中明确写到，学生应根据构词法知识知道一些词的衍生词。
所以我们在第一天学习英语中主要的三种构词法：第一是合成法，例raincoat（雨衣）是由rain和coat组成。
这样的词汇在英文中占很大的比重，所以在记忆单词的时候首先要看这个单词是否是合成词，如果是合成词只需要将其拆开，这样原本要的记上许多个不同字母的单词成了两个部分，记起来就非常省力。
第二是转化法，例如：水water，但在water the flower中却成了浇水的意思从名词转化成了动词。
这正是许多同学在阅读时认识句子中的每一个单词却不知道句子意思的原因，即词性发生了变化。
因此，在背单词中要有意识地注意词的这种变化，一个单词是否有意思相近的几个词性。
第三是派生法，就是通过加前缀和后缀改变单词的意思或词性。
这是我们要掌握的重点，掌握这些前后缀是十分必要的，能够使你迅速提高词汇量。
此外，掌握了这些前后缀及其构词原理，还能够使我们举一反三，有助于理解和学习一些新的词汇，相应地也就扩大了我们的词汇量。
前缀（Prefixes）一般不造成词类的转变，而只是引起意思上的变化请大家先来看这些大家很熟悉的词① honest ② like ③ able ④ possible ⑤ legal⑥ ever ⑦ sense ⑧ moral ⑨ regular现在让我们把他们的词义变成相反的词义① dishonest ② dislike ③ unable ④ impossible ⑤ illegal①不诚实②不喜欢③不能，不能的，不会的④不可能的，⑤违法的，不合规定的⑥ never ⑦ nonsense ⑧ immoral ⑨ irregular⑥决不，从未⑦胡说，废话⑧不道德的⑨不规则的常见的前缀一、表示否定意义的前缀un- 不做相反动作 dis- 不做相反动作 in- 不im- 不 ir- 不 il- 不 non- 不，非【猜一猜】① unhappy ② untrue ③ undress ④ undo ⑤ disagree(ment) ⑥disown⑦ disinfect ⑧ non-existent ⑨ non-conductor【key】①不高兴②不真实③暴露，使卸去装饰④解开，松开⑤不一致，不适合（争执，争论）⑥否认⑦消毒⑧不存在的⑨绝缘体二、表示前，先前意义的前缀husbandex-husband（前夫）seeforesee（预知，预见）historyprehistory（史前时期）claimproclaim（宣告，宣布）看完这单词的对比大家一定知道这一组前缀主要是表示前，先前，预先F 前缀ex-，汉语意思是“先前”，它主要是和表示“人”的名词搭配。

(1).第一次出现查找：NSUInteger index=[array indexOfObject:@"two"];//获取的是第一次出先这个数组元素的下标；结果：1
(2).范围出现查找： NSUInteger index1=[array indexOfObject:@"Two" inRange:NSMakeRange(2, 3)];//在下标为2开始查找3个数组元素; 结果：3
(3) [array removeObject:@"six"];
NSLog(@"%@",array);//删除，需谨慎删除，这个会删除所有相同的元素；可以用范围删除来控制删除的元素removeObject:<#(id)#> inRange:<#(NSRange)#>]
[array removeObject:@"six" inRange:NSMakeRange(3, 2)];//在一定范围内删除；从3往后找3个；

NOIP初赛资料——day3过程和函数
时，在TP中必须用
for j:=I+1 to 10 do
类型名进行定义，
if p[I]>p[j] then begin
而在FP中是可以这
k:=p[I];p[I]:=p[j];p[j]:=k;
样定义的：
end
end;
begin
for I:=1 to 10 do read(a[I]);
sort(a);
for I:=1 to 10 do write(a[I],‘ ’)
sum:=sum+s; writeln(‘sum=‘,sum:10:3); end.

过程和函数的主要区别：
P 程序设计 ascal
过
程
操 作 完成一系列的数据处理， 或与计算无关的各种操作
函
数
往往求一个函数值
结果类型
无
函数有类型，最终要将函 数值传送给函数名。
变量，它们并不占用内存单元，只是在调用函数时，才临时开
辟相应的内存单元，存放实在参数的值，如fac(3)中的3。它是
在调用函数时的所用的自变量。形参实质上是实参的一个“替
身”。在调用函数时，实参将值赋给形参，因此实参的个数、
类型应与形参一一对应，并且要有确定的值。
2、函数调用步骤是：首先在调用程序中计算实参的值，传送 给对应的形参，接着执行函数体，最后将函数值返回给调用程 序。
