•Complex Sentences

[1]. Original: The requirements document has tobe such that the client and users can understand it easily and the developers can use it as a basis for software development.

Translation: 需求文档必须能够让客户和用户容易理解，并且让开发人员能够将其作为软件开发的基础来使用。

[2]. Original Though use cases are meant for specification, as they are natural and story-like, by expressing them atdifferent levels of abstraction they can also be used for problem analysis.

Translation:尽管用例是为规格说明而设定的，但由于其自然性和故事性，通过在不同的抽象级别上表达用例，用例也可以用于问题分析。
