求助！遭遇保底学校老师逼宫，该怎么办？

之前被反套，联系了几次，老师就来邮件逼宫，求助各位高手，我该怎么回复？毕竟是第一个offer，我还不想放弃啊。
这是老师发来的邮件：
I am planning to offer an research assistantship to you. Before I
start the paperwork, I want to check with you to make sure that
you once you receive the offer, you will accept the offer and will
come here, with a goal of finishing the Ph.D. degree.

拜谢各位了~

这个写的很好！

其实这种问题，没有什么标准的或者完美的解决方案，如果觉得去了不甘心，应该会有更好的offer，可以按照ls说的。

Although your school indeed attracts me and I also want to attend your group, most of my applications are currently underway, among which are my dream schools.

But I can promise your offer is very precious to me, and I would inform you my final decision as soon as possible.

这老师也太不厚道了。。我劝你能拖先拖着，不能拖就拒了他。。

这样的老师即使你去了还要遭5年的罪，还不如不去

phd老师最重要了。。

同感………………求贤若渴的心情可以理解，但这样做的确是不厚道……

说的很有道理，只是这是第一个伪offer，不好轻易放弃。

你说的拖，我也有同感，只是不知道怎么表达，可否给一点更细一点的建议？
非常感谢！

非常感谢，写的很不错~THANKS~

我倒觉得光从这封信看不出这个教授人不好啊～他说的是start paperwork么，可以理解

值得借鉴
