新东方老师讲的时候说convince有两种用法1.convince sb. of sth.2.convince that...和宾语从句搭配，没有宾语时采用主系表结构：be convinced,然后紧接着举了个例子，说道：“The experts from the zoo were convinced that the animal was a puma.专家们相信了那个动物就是一只美洲豹。只是强调了专家们相信了，并没说使谁相信。 我相信她是一个城市的女孩，I'm convinced that she is a honest girl。所以没有宾语的情况下要采用主系表结构。”为什么她说The experts from the zoo were convinced that the animal was a puma.I'm convinced that she is a honest girl这两句话没有宾语呢？到底convince that 和be convinced有什么区别啊？能不能给点例句。
參考答案:The experts from the zoo were convinced that the animal was a puma. 分析一下这个句子，the expert是主语。from the zoo是定语，修饰the expert。were convinced 是被动语态，
convince that 主动语态
