Can I get an extension on the deadline to the end of the week?
可以看作on the deadline和 to the end of the week都是extesion 的定语吗?在如此结构的句子中,介词都是固定的搭配吗?
Can I get an extension on the deadline to the end of the week?
on 应为 of .
extend A to B 把A延伸到B。动词结构改为同源名词结构时,宾语用of 引出,状语不变,得到an extension of A to B. 此时of 介词短语和to 介词短语都是extension的定语了。
