the kind
问题描述：
the kind
1.The army was ideologically opposed to the kind of
economic solution proposed.
2.for fear the agents of other firms should be able to trace the kind of research they are likely to be undertaking.
句中the kind of 好像不加也不影响吧?
答
此处的the kind of是强调某一种种类,比如第一句就是强调当前提出的这一类经济措施,第二句就是强调他们可能开展的这一类研究.
不加语法上是没有问题的,但是语义的过渡衔接显然不如加上the kind of好.undertaking 为什么用进行时？
likely to undertake 也可以吧？be likely to do可能准备做某事
be likely to be doing可能正在做某事
likely to undertake语法上可以，但要考虑语义，此处强调的是正在开展的研究，所以用be likely to be doing.
