Most sequential circuits contain a combinational logic section and a memory section.（）

A．Sequential logic circuits require a means by which events can be sequenced,so do combinational logic circuits.

B．Sequential logic circuits require a means by which events can be sequenced,while combinational logic circuits do not neeD

C．Combinational logic circuits are perfect for situations when we require the immediate application of a Boolean function to a set of inputs, however, sequential logic circuits to change its value with consideration to its current state as well as its inputs.

三个领导,三种风格刚刚大学毕业的吴君通过学校推荐来到钢材集团总公司下属的第三分公司,给张总经理作秘书。张总经理可谓日理万机,因为公司的大小事情都必须要向他汇报,得到他的指示才能行事。尽管如此吴君感到工作还是比较轻松。因为任何事情她只是需要交给总经理,再把总经理的答复转给相关责任人,就算完成任务了。可是好景不长,因为张总经理每日太过奔波劳碌,终于病倒了。 新上任了王总经理。王总经理开始对吴君每日无论大小事宜都要请示提出了批评,让她慢慢学会分清轻重缓急,有些事情可以直接转交其他副总经理处理。这样,王总经理每日有更多的时间去考虑公司的长远目标,确立组织发展方向,然后在高层领导者之间召开会议,进行研讨。自王总经理上任以来,公司出台了新的发展战略、市场定位及公司内部的规章制度。公司的业绩也在短期内有了很大的提高。同时,吴君也很忙碌,有时需要跑很多的部门去协调一件工作,让她觉得学到了很多东西,也充实了不少。因为业绩突出,王总经理干了一年就被调到总公司去了。 之后又来了李总经理。相对于张总经理的事必躬亲以及王总经理的有张有弛,李总经理就要随意得多了。他到任之后,先是了解了一下公司的总体情况,感到非常满意。 就对下面的经理说: “ 公司目前的运营一切顺利。我看大家都做得比较到位,总经理嘛,关键时刻把把关就可以了,不是很重要的事情你们就看着办吧。 ” 选样一来,吴君享受到了自工作以来没有过的轻松,因为一周也没有几件事情要找总经理。 吴君现在有时问了,她对比、思考着这三个领导,真是各有各的特点。 问题: 1 .认为三个领导的风格有区别吗 ? 请按照所学的情境领导模型进行归类。 2 .认为哪个领导的管理风格更可取 ?
