[单选题]Organizations perform work to achieve a set of objectives. Generally, work can be categorized as either projects or operations, although the two sometimes are（）

正确答案 ：C

overlap

解析：该题的关键词为"categorizedprojects or operations"，其语句结构为"Generally,work（主语）can be categorized（谓语）as either projects or operations, althoughthe two（主语）sometimes are（）（谓语）"，含义为"通常，工作可以分类为项目型和运作型工作，尽管两者有时(?)"，因两者既有相同之处，也有不同的地方，所以选择C。选项D对应的单词"dissever"疑为拼写有误。

[单选题]During the project, requirements change for a variety of reasons.

The project manager may, however, want to track appropriate measures of requirements volatility to judge whether new or revised（）are necessary.

正确答案 ：B

controls

解析：该题的关键词为"appropriate measures、 requirements volatility"，其语句结构为"The project manager（主{吾） may, however, want to track（谓{吾） appropriate measures of requirements volatility（宾语） to judge whether new or revised（）are necessary（目的状语从句）"，含义为"项目经理也许会跟踪需求变化的相关度量，以判断是否应该调整的或者新的什么"，因为整段文字讨论的内容都集中于需求变更管理，所以只分析最后一句即可，根据题意，应该在空白处填写"措施"一类的词汇，排除之后只有选项B比较适合，选项A、C和D都可以排除，尤其是选项D是一个很生僻的词汇，含义为"尝试"。
