Question

with something she needed to buy,she went to the marketplace.

with everything she needed bought ,she went to the marketplace.
两句话的区别是什么？重点分析一下前一句，谢谢。

Answer 1

首先，表达含义不一样啊~~
With something she needed to buy,she went to the marketplace.
这句话是with+不定式的结构，不定式表目的。
译句：（因为）有要买的东西，她去了超市。

With everything she needed bought ,she went to the marketplace.
而这句话是with+done的结构，表示已经完成的动作。
这句话的后半句是你自己写的还是书上原话？按理说不应该是marketplace而是home吧？？
译句：该买的都买完了，她回家了。

希望能够帮助到你！！不懂请追问！！O(∩_∩)O

Answer 2

With something she needed to buy,she went to the marketplace.
with+不定式的结构，不定式表目的。
（因为）有要买的东西，她去了超市。

with everything (which/that) she needed bought ,she went to the marketplace.
这句话是个定语从句，省略了 which或that. bought 这里用过去分词形式做形容词修饰needed，需要买的东西。
