Paraphrasing (2nd paragraph)
Text
The WT0 does not have a compliance system per Se; it has a dispute settlement system. The Dispute Settlement Body （DSB） is only seized of matters when a WTO Member government lodges a complaint about a dispute where the complaining government believes that benefits accruing to it are being impaired by the actions of another Member government. The Dispute Settlement Understanding （DSU） refers to this as a "case" which arises out of a "dispute". Thus, a mere allegation of noncompliance without more, or a disagreement as to the interpretation of the WTO treaty, are not technically within the ambit of the WTO dispute system
The main idea of the paragraph
The WTO dispute settlement system handles a complaint made by one member government about the benefits accruing to it being impaired by the actions of another member government, but not disagreement concerning the interpretation of the WTO treaty or a mere allegation of non-compliance without more.
世贸组织的争端解决机构处理一个世贸组织成员国政府就其利益正受到另一个成员国政府行为损害而提出的投诉，它不受理就世贸组织条约解释上的差异引起的争议，也不受理仅一次的未尊约。
词语解释
The Dispute Settlement Body （DSB） is only seized of matters when a WTO Member government lodges a complaint about a dispute where the complaining government believes that benefits accruing to it are being impaired by the actions of another Member government.
在此句中
1）“The Dispute Settlement Body （DSB） is only seized of matters”是主句；
2）“when a WTO Member government … another Member government”是时间状语从句，说明主句中谓语动词发生的时间，其中“where the complaining government … government”是限制性的定语从句，修饰名词“dispute”，在定语从句中还有一个由“that”引导的从句，作动词“believes”的宾语；另外，现在分词短语“accruing to it”作定语，修饰名词“benefits”。
