这也是我曾经疑惑的问题。不过后来做题多了之后慢慢就理解了。
最重要的是题干里有plan, 有这个plan但不一定就能达到所plan的水平; 文中提到的计划水平是制造商自己YY的, 因此需要用假设, 因为并没有实际发生.
一般看到有plan, tendency都需要注意是不是要用虚拟语气.

给LZ另外一道题参考一下, 我想假设要多体会胜过言语的讲解. OG12 NO.41,
To develop more accurate population forecasts, demographers [have to know a great deal more than now about the social and economic] determinants of fertility.
A. have to know a great deal more than now about the social and economic
B. have to know a great deal more than they do now about the social and economical
C. would have to know a great deal more than they do now about the social and economical
D. would have to know a great deal more than they do now about the social and economic
E. would have to know a great deal more than now about the social and economical

OA

这题OG的解释就是说demographer要达到这个目的,他们需要, 他们也有这个意愿要去知道多一点, 所以这里用了would来表达意愿, 而假设的含义没有那么浓.

不是NN..还请NN指正....
