答：主要区别在于：

　　The main differences：

　　关贸总协定是临时的。从未得到成员立法机构的批准，也未包括创立一个机构的条款。

　　GATT was ad hoc and provisional. The General Agreement was never ratified¹ in member's parliaments, and it contained no provisions for the creation of an organization.

　　世界贸易组织及世贸协议是永久性的。作为一个国际组织，世界贸易组织由于成员的立法机构批准了世贸协议，且世贸协议本身描述了世贸的运作方式，因而有了很好的法律基础。

　　The WTO and its agreements are permanent. As an international organization, the WTO has a sound legal basis because members have ratified the WTO agreements and the agreements themselves describe how the WTO is to function
