这句英文漏了什么

1.laugh at 嘲笑
laugh 笑，只表示笑这个动作。
eg:Please don't be offended, we were laughing with you, not at you.
请别见怪，我们是在和你一起笑，而不是嘲笑你。
2. be willing to do 愿意做……

加上was,because 后面要加完整的句子，没有be动词句子破碎，不完整。

because of 后加名词

Qiao was laughed by people because he was always willing to help others
漏was

应该有was,he was always willing to help others
be willing to do sth.

he 后面加 IS

laughed 后面加at
laugh at sb 嘲笑某人。固定词组
