比如Romain Gary的小说 Promise at dawn 也出现了这个表达：
fend for （oneself）
If you have to fend for yourself, you have to look after yourself without relying on help from anyone else.
The woman and her young baby had been thrown out and left to fend for themselves.
《金融时报》一篇题为 A race to vaccinate the developing world 也出现了这个表达：
这里再补充一个短语：fend off 挡开，避开(问题或人) 【If you fend off unwanted questions, problems, or people, you stop them from affecting you or defend yourself from them, but often only for a short time and without dealing with them completely.】
He had struggled to pay off creditors but couldn't fend them off any longer.
它还有一个意思，表示“挡住，抵挡(攻击) ”【If you fend off someone who is attacking you, you use your arms or something such as a stick to defend yourself from their blows.】
He raised his hand to fend off the blow.
