叫人赞助的话怎么说英语

To ask someone to sponsor something, you can say:

"Would you be willing to sponsor this event/project/cause?"

"We are looking for sponsors to help us make this happen. Would you be interested in supporting us?"

"We would greatly appreciate your support as a sponsor. Could you contribute financially to help us achieve our goals?"

Remember to be polite and explain the details of what you are asking for sponsorship for, and how their contribution will be used. It's also a good idea to offer various levels of sponsorship, so that the person can choose the level that is most comfortable for them.
