D.strict答案：A解析：题意想要表达的意思是要求大量陈述的要求很难描述的步骤和事件序列。正确答案为A，大量的，充足的。附（参考翻译）：在一个似乎已经有做不完的事情的世界里，我们有大量事情要思考，似乎我们不太需要学习新的东西。但是用例解决问题是有条件的：严密的说明性需求使得描述事件的步骤和次序变得举步维艰。简单地讲，用例描述一组事件序列，系统性地执行产生相应有用的结果。听上去简单明了，这是很重要的。当面对一大堆的需求时，通常不太可能理解这些需求的发起者到底想要系统做什么。在前面的案例中，用例通过详细准确描述什么时间、什么情况下确定的行为会发生，以减少需求的不确定。像这样的一些动作序列被看作是一个需求。用例特别适合于捕捉方法。虽然这听起来很简单，但事实上不同的需求会根据他们各自在说明性需求和“应有”的声明的侧重面上捕捉方法，导致完全无法捕捉到系统行为的初衷。用例是一个所有的利益相关者都可以很容易地理解的、简单却十分有效的表达系统的行为的方式。但是，和其他任何事情一样，用例也存在自身的问题，可能会被误用而弄巧成拙。造成的后果也很糟糕，或许只是没有比原本想要解决的问题更麻烦罢了。因此有效使用用例而避免制造更大的麻烦是非常重要的。 -
第6题：
In a world where
it seems we already have too much to do, and too many things to think about, it
seems the last thing we need is something new that we have to learn.
But use cases do
solve a problem with requirements:with （71） declarative requirements it's hard to describe steps and sequences of
events.
Use cases, stated
simply, allow description of sequences of events that, taken together, lead to
a system doing something useful.As simple as this sounds,this is important.
When confronted only with a pile of requiements, it's often（72）to make sense of what the authors of the
requirements really wanted the system to do.In the preceding example, use cases
reduce the ambiguity of the requirements by specifying exactly when and under
what conditions certain behavior occurs;as such, the sequence of the behaviors can
be regarded as a requirement. Use cases are particularly well suited to capture
approaches. Although this may sound simple, the fact is that （73） requirement capture approaches, with their
emphasis on declarative requirements and "shall"
statements,completely fail to capture fail to capture the （74） of the system's behavior. Use cases are a
simple yet powerful way to express the behavior of the system in way that all
stakeholders can easily understand.
But,like
anything, use cases come with their own problems, and as useful as they
are,they can be （75）. The result is something that is as bad, if not worse, that the original
problem.Therein it's important to utilize use cases effectively without
creating a greater problem than the one you started with.A.plenty
B.loose
C.extra
D.strict答案：D解析：在这个世界上，似乎我们有太多的事情要去做，有太多的事情要去思考，那么需要做的最后一件事就是必须学习新事物。 而用例恰恰可以解决带有需求的问题：如果具有严格声明的需求，则很难描述事件的步骤和序列。 简单地说，用例可以将事件序列的说明放在一起，引导系统完成有用的任务。正如听起来一样简单---这很重要。在面对很多需求的时候，通常不太可能理解需求的作者真正想要系统做什么。在前面的例子中，通过指定特定行为发生的时间和条件，用例减少了需求的不确定性。这样的话，行为的顺序就可以当作是一种需求。用例特别适用于捕捉这类需求。尽管听起来可能很简单，但事实情况是由于常规的需求捕捉方法所侧重的是声明需求和“应该怎么样”的陈述，因此完全无法捕捉系统行为的动态方面。用例是一种简单而有效的表达系统行为的方式，使用这种方式所有参与者都很容易理解。 但是与任何事物一样，用例也存在自己的问题---在用例非常有用的同时，人们也可能误用它，结果就产生了比原来更为糟糕的问题。因此重点在于：如何有效地使用用例，而又不会产生比原来更严重的问题。
