以下是引用jennyjia1985在2008-10-7 23:30:00的发言:

abx>aby?

1. ax>ay

2. bx>by

这个是不是选c?

C肯定是不对的吧。应该选E吧,1+2可以推出,ab>0 (无论x>y,or x<y)

请nn鉴定

An=A1*A2*A3*...*An-1,已知An=t,问An+2等于多少。偶选的是t^3。

还有一个:说一个人每天做一个entry,从周三开始做,1000天时是周几?想了半天,最后选了周一。

An=A1*A2*A3*...*An-1,已知An=t,问An+2等于多少 

这题应该是t^4吧

gwd有一个黑人工会的阅读,是不是你说的这个?

       In the 1930’s and 1940’s,
            
African American industrial workers in the southern United States, who constituted 80 percent of the unskilled factory labor force there, strongly supported unionization. While the American Federation of Labor (AFL) either excluded African Americans or maintained racially segregated unions, the Congress of Industrial Organizations (CIO) organized integrated unions nationwide on the basis of a stated policy of equal rights for all, and African American unionists provided the CIO’s backbone. Yet it can be argued that through contracts negotiated and enforced by White union members, unions—CIO unions not excluded—were often instrumental in maintaining the occupational segregation and other forms of racial discrimination that kept African Americans socially and economically oppressed during this period. However, recognizing employers’ power over workers as a central factor in African Americans’ economic marginal ization, African American workers saw the need to join with White workers in seeking change despite White unionists’ toleration of or support for racial discrimination. The persistent efforts of African American unionists eventually paid off: many became highly effective organizers, gaining the respect of even racist White unionists by winning victories for White as well as African American workers. African American unionists thus succeeded in strengthening the unions while using them as instruments of African Americans’ economic empowerment.

以下是引用vivianyajun在2008-10-7 23:16:00的发言:

问这道题怎么解?

7. 某数列为连续数列,个数是否大于6
  
12 multiples of 5  2) 3 multiples of 3

1)  5    10

2) 3  6    9          => 3  4 5 6 7 8 9 10        共7个> 6个,

                               9  10  11  12 13 14 15  也行,

因此选C,  对吗?
