19.   Ans: A 请问推理过程? E选项为何不对?

Recent estimates predict that between 1982 and 1995 the greatest increase in the number of people employed will be in the category of low-paying service occupations. This category, however, will not increase its share of total employment, whereas the category of high-paying service occupations will increase its share.

If the estimates above are accurate, which of the following conclusions can be drawn?

(A) In 1982 more people were working in low-paying service occupations than were working in high-paying service occupations.

(B) In 1995 more people will be working in high-paying service occupations than will be working in low-paying service occupations.

(C) Nonservice occupations will account for the same share of total employment in 1995 as in 1982.

(D) Many of the people who were working in low-paying service occupations in 1982 will be working in high-paying service occupations by 1995.（A）

(E) The rate of growth for low-paying service occupations will be greater than the overall rate of employment growth between 1982 and 1995.

20.   Ans: C, B选项为何不对?

For a local government to outlaw all strikes by its workers is a costly mistake, because all its labor disputes must then be settled by binding arbitration, without any negotiated public-sector labor settlements guiding the arbitrators. Strikes should be outlawed only for categories of public-sector workers for whose services no acceptable substitute exists.

The statements above best support which of the following conclusions?

(A) Where public-service workers are permitted to strike, contract negotiations with those workers are typically settled without a strike.

(B) Where strikes by all categories of pubic-sector workers are outlawed, no acceptable substitutes for the services provided by any of those workers are available.

(C) Binding arbitration tends to be more advantageous for public-service workers where it is the only available means of settling labor disputes with such workers.

(D) Most categories of public-sector workers have no counterparts in the private sector.（C）

(E) A strike by workers in a local government is unlikely to be settled without help from an arbitrator.

2。19题：low-paying service occupations就业人数增加最大，SHARE却没随着增加。说明就业人数增加速度小于总就业人数增加速度。故E错。 high-paying service occupations 的SHARE增加，说明它的就业增加速度大于总就业人数增加速度。所以也就大于low-paying service occupations就业人数增加速度。就业人数增加速度=增加的就业人数/就业人数（1982）。由于对low-paying service occupations，速度小于high-paying service occupations ，增加的就业人数（分子）大于high-paying service occupations 。所以就业人数（1982）（分母）肯定大于high-paying service occupations （1982）。即A

20 题, 有两个逻辑：

一、结论B：  禁止所有罢工代价高昂  （宣布所有罢工为非法代价高昂）

    原因A：  解决劳动争端的仲裁没有磋商的协议指导 [本来所有的争端都应该靠有

约束力的(binding)仲裁解决，但仲裁却没有（经磋商出来的）公共部门的劳动协议的指导]

那么：B <--- A 隐含的条件是： 有磋商性协议指导，则禁止罢工代价不高昂。

     该逻辑可以推出： 有（经磋商出来的）公共部门的劳动协议指导的仲裁，禁止公共部门的罢工代价不高昂。 因此答案为C

二、结论B： 公共部门罢工要被禁止

    原因A： 公共部门的服务无替代品 

    由B <--- A 可以推出： 服务无替代品的部门罢工要被禁止。  而（B）答案是第二个逻辑的原因的重复，不能被推出。
