名词不能用单数形式的短语

《大学英语》第二册第八课有这样一句话"…,so that one of the first steps necessary was for ar-rangments to be made for these to be printed andpublished."其中"arrangements to be made for"写成短语应为"to make arrangements for",意为"为…作安排/准备"。在这个短语中 arrangement 须采用复数形式,不能用单数形式。下面就在以名词为核心的短语中,名词只能用复数形式的问题作一下探讨。一、表示安排、准备含意的短语1.make preparations for/to do sth.为(干)某事作准备。例如:Xiao Wang is making preparations for theconference.小王在为会议作准备。2.make arrangements for/to do sth.为(干)某事作安排/准备。例如:Arrangements have been made to give the for-eign guests a warm welcome.
