He said that he could speak both english and frenc

这个似乎辨的太细了.this指代上文提到的事,一般不单独使用,而是会再重复提到这件事,如：There was a court case resulting from this accident.（accident重复出现）.What’s this i hear about you getting married?再比如The boy was afraid and the dog had sensed this.这句话以and连接,句中没有逗号分隔,这样提到的事件与this的关系就很密切（注意这句话中用that也是可以的）.而你给出的这句话有两个分句,that单独使用代替第一个分句提到的内容.因此,只能说,这里选用that比this更好一些,而this也并不能说它错.
