(E) Without natural predators and with expanses of green suburban neighborhoods where there is no hunting, wildlife officials in New Jersey estimate a deer population that has
正确答案C
语法笔记说 with结构句首，所以主语要是deer population。
想请问：
1，with介宾在句首是否主句主语要求是逻辑主语。另外，这个with+n. and with + n. 结构所说的逻辑主语是否就是它所修饰的对象的意思？
2，如果是，那么C中 deer population并不等于deer， 刚看到前人帖子说：population可做鹿群解释，如果是做鹿群解释，那么鹿群grow to 175000似乎也不太合理，该是数字grow。

再补充问下， estimate sth that 可以吗？ estimate sth to have也可以？ 以及，C. Wildlife officials estimate 是什么成分？作者: sogapink 时间: 2012-4-13 06:57
1. 表示原因，此时不需要考虑逻辑主语，只是修饰前面整句
2. 表示伴随动作(非伴随结果)，此时需要注意逻辑主语，且前面不能是完成时态(这样就不能伴随动作了).（with短语要表示伴随结果则需要用with the result of，如prep2-193）.
3. 表示状态（此时前面需要是主系表），同样需要逻辑主语。
