Last year a record number of new manufacturing jobs were created. Will this year bring another record? Well, any new manufacturing job is created either within an existing company or by the start-up of a new company. Within existing firms, new jobs have been created this year at well below last year’s record pace. At the same time, there is considerable evidence that the number of new companies starting up will be no higher this year than it was last year and there is no reason to think that the new companies starting up this year will create more jobs per company than did last year’s start-ups. So clearly, the number of new jobs created this year will fall short of last year’s record.

The first is presented as an obvious truth on which the argument is based; the second is the main conclusion of the argument.

考题讲解

情景：去年创造了很多制造业的岗位。今年会有一个新纪录吗？任何新的制造业岗位要不然是来自一个已经存在的公司，要不然是来自一个新成立的公司。在已经存在的公司里，今年创造的新岗位已经远低于去年的节奏了。同时，也有充分的证据显示今年新成立的公司的数量也远低于去年，并且没有理由认为，每家今年新成立公司会比每家去年新成立公司创造更多的岗位。所以，今年新岗位的数量会低于去年的数量。
