A：Yes, but you’re assuming that we’ve got to start from scratch and that’s not actually the case. It’s not as pricey a job as you think. There’s no need to reinvent the wheel, here. We can just take an existing piece of software and rework it.

B：You say that, but I know what these projects are like. You imagine it’s all going to be plain sailing, but then you inevitably run into one problem after another and before you know it, the costs have spiraled out of control.

A：Of course there would be teething problems – there are with any project. And of course we would have to cost that in. But I’m sure we can find some middle ground with them.

B：OK, but if it all goes pear-shaped, don’t say I didn’t warn you.

请教曹老师，刘老师！there are后面应该省略了problem，那么对表示针对某件事情时，借词with与for在使用上究竟有着怎样的区别，我一直有点傻傻分不清，希望老师能详细解析一下。
