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.

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 employmnet in 1995 as in 1982.

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

e. The rate of growth for low-paying service occupations will be greater than the overall rate of employment growth between 1982 and 1995.
. 答案选a
请问大家,这道题里有没有用到数学的思想呢? 为什么low-paying就业人数 增加的最多,但是占整个就业人数的比例不变, 而high-paying的就业人数占整个的比例增加,就能得出a的结论?

2. 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 guilding the arbitrators. strikes should be outlawed only for categories of public-sector workers for whose services no acceptable substitute exists.

a.Where public-service workers are permitted to strike, contract negotations with those workers are typically settled without a strike.

b. where strikes by all categories of public-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.

e. A strike by workers in a local government is unlikely to be settled without help from an arbitrator.
答案选c, 可是我觉得b没错呀, 题里不是说在没有别的替代的情况下, 可以禁止罢工, 那要是某地区所有部门都被禁止罢工,不是说明他们没有别的替代方法吗?我有点糊涂,谢谢xdjm帮我解释一下? 这回我把选项都写出来了

楼主， 题目呢？  没有题目怎么想啊！^8^
再说下去别人以为我在为难你呢. 别生气哦,不过下次要记住了

第一题是比例题,想想吧
第二题b是过于绝对了，看看题目再比较一下B

天哪,真不好意思! 我怎么那么粗心,哇~~~~~~~~~~sorry !
第一题问: If the extimates above are accurate , which of the following conclusions can be drwan?

第二题问: The statements above best support whcih of the following conclusion?

stoneren

第一题举个例子：
low-paying 1982(9人)，1995(9+7人)
high-paying 1982(1人), 1995(1+3人)
rate自己算吧

第二题
问题的关键在于costly mistake，那么，去找个能说明这个问题的答案，只有B

kittyinuk

嗯! 谢谢stoneren和StephanieYun 二位GG,MM , 你们真好!

对了,顺便问一句, 第二题选项B 和C 能不能这样区分: 因为题干中的逻辑关系是:
if no substitutes available-------> then, outlaw strikes(原命题) 但是B的意思是 if outlaw strikes------> no substitutes availabe(逆命题). 但是原命题成立是不能推出逆命题成立的.
但是C选项就没说得那么绝对, 而且含的关键字更多(binding arbitration,  settling labor disputes) ?

StephanieYun

第二题原文中与B相对应的内容不是你理解命题吧，你再看看吧，好像刚好相反了。

另外，曾听新东方老师说过关键字越多，选项就越有可能正确，------小女子有点提醒，一定要小心这个方法，可能会导致错误的选择。 因为关键字越多，错误的可能也随之增大。
