前者正确.可不是应该be happy with sth吗是的是的那么be happy that 不是缺少with连接吗be happy that 中that 引导的是原因状语从句，说明高兴的原因，相当于because 引导的句子。“be+形容词+that从句”是英语的表达方式之一，例如: I am very happy that you could visit us. "您能来拜访我们，我们很高兴"。 再例如: He was glad that he had made great progress in his study. "他很高兴自己在学习中取得了很大的进步"。短语be afraid ofI am afraid that he will not come this afternoon.” “你会说be afraid of that吗Think of sth但宾语从句为I think that希望能帮到你，满意的话记得采纳。
