复习一周690……纠结再考不……贡献一点jj

寒假无聊考着玩考了一次……真的无聊考着玩的,因为没有什么出国的强大动力……那个时候就是复习了一周,做了紫皮和绿皮,模考了两次prep,做了几套GWD错的一塌糊涂……在上海考了640.

后来觉得这玩意挺给人成就感的……就又报了5月8号的……又零零散散复习了一周……在广州考,呜呜,之前一天室友mm流感,害我一晚没睡好……分数很鸡肋,690。当然在CD就属于被鄙视的那种了……但是现在读双学位真的很累,不想再考了。但是又觉得还有很大提升空间,不如月底再考一下趁着jj最多的时候再接再厉……不知道怎么办……请求大家建议一下吧……

数学确实比较难了,比我寒假随便考的时候难不少,可能因为这次考前我完全一点数学没复习,之看了几眼jj。只记得第一题是(h-x)/(y-h)=x/y,问h是下列哪一项的平均值的倒数?a,x^2,y^2  b,1/x, 1/y,还有几个什么,我好像是选的b

阅读遇到了那个什么shell mount题……完全没懂。还有那个黑人白人农民1890到1930因人多土地少被影响移民的,jj都有。记得最后一篇是火星上有记录表明曾经有水,ms这篇是GWD上的还是哪里的,反正看过……有两段,第一部分讲有channel是被flood冲刷过的痕迹,第二部分讲另外一个证据,但是似乎又说明没水……

我pace真是差……数学做完还有几分钟,语文就还有两三题没做……sigh……这次考前一次都没按照时间模考过……真是不行……

又想起几道数学……挺麻烦的。这次狂多坐标题:

1,由x>=2,y>=3和y=9-x围成的图形面积

2,三个点,A,B,C,给了坐标了,问c点到经过AB的直线的距离。最后是根号5.

3.一个code由三个不同数字组成,每个数字从1到20里面选择,问有多少种组成。数字都很大,什么2000多,6000多,7980,还有9000多的。我选的6000多。

4.gap被定义为a和b两个整数间数字的个数,问2到29之间所有两两质数之间的gap的均值是多少……什么2.8啦2.4啦3.0啦……我做出來没一个对的><

LZ MM 看下,黑人 白人 迁徙的是下面这个吗?谢谢!

In the two decades between 1910 and 1930, over ten percent of the Black population of the United States left the South, where the preponderance of the Black population had been located, and migrated to northern states, with the largest number moving, it is claimed, between 1916 and 1918. It has been frequently assumed, but not proved, that the majority of the migrants in what has come to be called the Great Migration came from rural areas and were motivated by two concurrent factors: the collapse of the cotton industry following the boll weevil (boll weevil: n. 棉籽象鼻虫) infestation, which began in 1898, and increased demand in the North for labor following the cessation of European immigration caused by the outbreak of the First World War in 1914. This assumption has led to the conclusion that the migrants’ subsequent lack of economic mobility in the North is tied to rural background, a background that implies unfamiliarity with urban living and a lack of industrial skills.

But the question of who actually left the South has never been rigorously investigated. Although numerous investigations document an exodus from rural southern areas to southern cities prior to the Great Migration, no one has considered whether the same migrants then moved on to northern cities. In 1910 over 600,000 Black workers, or ten percent of the Black work force, reported themselves to be engaged in “manufacturing and mechanical pursuits,” the federal census category roughly encompassing the entire industrial sector. The Great Migration could easily have been made up entirely of this group and their families. It is perhaps surprising to argue that an employed population could be enticed to move, but an explanation lies in the labor conditions then prevalent in the South.

About thirty-five percent of the urban Black population in the South was engaged in skilled trades. Some were from the old artisan class of slavery—blacksmiths, masons, carpenters—which had had a monopoly of certain trades, but they were gradually being pushed out by competition, mechanization, and obsolescence. The remaining sixty-five percent, more recently urbanized, worked in newly developed industries—tobacco, lumber, coal and iron manufacture, and railroads. Wages in the South, however, were low, and Black workers were aware, through labor recruiters and the Black press, that they could earn more even as unskilled workers in the North than they could as artisans in the South. After the boll weevil infestation, urban Black workers faced competition from the continuing influx of both Black and White rural workers, who were driven to undercut the wages formerly paid for industrial jobs. Thus, a move north would be seen as advantageous to a group that was already urbanized and steadily employed, and the easy conclusion tying their subsequent economic problems in the North to their rural background comes into question.

1.     The author indicates explicitly that which of the following records has been a source of information in her investigation?

(A) United States Immigration Service reports from 1914 to 1930

(B) Payrolls of southern manufacturing firms between 1910 and 1930

(C) The volume of cotton exports between 1898 and 1910

(D) The federal census of 1910D
                

(E) Advertisements of labor recruiters appearing in southern newspapers after 1910

2.     In the passage, the author anticipates which of the following as a possible objection to her argument?

(A) It is uncertain how many people actually migrated during the Great Migration.

(B) The eventual economic status of the Great Migration migrants has not been adequately traced.

(C) It is not likely that people with steady jobs would have reason to move to another area of the country.

(D) It is not true that the term “manufacturing and mechanical pursuits” actually encompasses the entire industrial sector.C
                

(E) Of the Black workers living in southern cities, only those in a small number of trades were threatened by obsolescence.

3.     According to the passage, which of the following is true of wages in southern cities in 1910?

(A) They were being pushed lower as a result of increased competition.

(B) They had begun t to rise so that southern industry could attract rural workers.

(C) They had increased for skilled workers but decreased for unskilled workers.

(D) They had increased in large southern cities but decreased in small southern cities.A
                

(E) They had increased in newly developed industries but decreased in the older trades.

4.     The author cites each of the following as possible influences in a Black worker’s decision to migrate north in the Great Migration EXCEPT

(A) wage levels in northern cities

(B) labor recruiters

(C) competition from rural workers

(D) voting rights in northern statesD
                

(E) the Black press

5.     It can be inferred from the passage that the “easy conclusion” mentioned in line 53 is based on which of the following assumptions?

(A) People who migrate from rural areas to large cities usually do so for economic reasons.

(B) Most people who leave rural areas to take jobs in cities return to rural areas as soon as it is financially possible for them to do so.

(C) People with rural backgrounds are less likely to succeed economically in cities than are those with urban backgrounds.

(D) Most people who were once skilled workers are not willing to work as unskilled workers.C
                

(E) People who migrate from their birthplaces to other regions of country seldom undertake a second migration.

6.     The primary purpose of the passage is to

(A) support an alternative to an accepted methodology

(B) present evidence that resolves a contradiction

(C) introduce a recently discovered source of information

(D) challenge a widely accepted explanationD
                

(E) argue that a discarded theory deserves new attention

7.     According to information in the passage, which of the following is a correct sequence of groups of workers, from highest paid to lowest paid, in the period between 1910 and 1930?

(B) Artisans in the North and South; unskilled workers in the North; unskilled workers in the South

(B) The effect of migration on the regional economies of the United States following the First World War

(C) The transition from a rural to an urban existence for those who migrated in the Great Migration

很确定不是这篇……里面的时间段就是1890到1910,还挺长的……
