某局机关因工作需要新成立了一个行政处，由局原办公室副主任李佳任处长，原办公室的8位后勤服务人员全部转到行政处。李佳上任后便到处物色人才，又从别的单位调进5位工作人员。这样，一个14人的行政处便开始了正常工作。李佳38岁，年富力强，精力旺盛，在没有配备副手的情况下，他领导其他13人开展工作。开始倒没什么，时间长了，问题也就多了。因为处里不管是工作分配、组织协调还是指导监督、对外联络，都是李佳拍板定案。尽管他工作认真负责每日起早贪黑，也适应不了如此繁荣的事务，哪个地方照顾不到都会出漏子，行政处内部开始闹矛盾，与其他处室也发生了不少冲突。 在这种情况下，局领导决定调出李佳，派局办公室另一位副主任王强接任行政处处长。王强上任后，首先，着手组建行政处内部组织机构，处下设置四个二级机构：办公室、行政一科、行政二科、行政三科。其次，选调得力干将，再从原来的局办公室过调两位主任科员任行政处副处长，从业务处进调3位副主任科员任行政一、二、三科的科长，其余科长、副科长在原13名工作人员中产生。王强采取这些做法，目的就是改变处里沉闷的空气，调动大家的工作积极性，提高行政处的工作效率。 这样，一个19人的行政处在3位正副处长、8位正副科长的领导下，再次以新的面貌投入到工作之中。但是过了不久，行政处的工作效率不仅没有提高，反而更加糟糕了。有的下属认为王强经常越权乱指挥，他们的工作没法开展，有的下属则认为王强到处包办代替，没事找事干，和科长争权；有的人认为行政处官多兵少，没有正经干活的，不到半年行政处又陷入重重矛盾之中。不但人际关系紧张复杂而且大家都没干劲。他很困惑：自己工作热情很高，为什么还领导不好行政处的工作 问题：李佳和王强失败的主要原因是什么应如何改进

阅读理解。

     How could we possibly think that keeping animals in cages in unnatural environments-mostly for

entertainment purposes-is fair and respectful? Zoo officials say they are concerned about animals. However,

most zoos remain "collection" of interesting "things" rather than protective habitats (栖息地).

     Zoos teach people that it is acceptable to keep animals bored, lonely, and far from their natural homes.

     Zoos claim to educate people and save endangered species, but visitors leave zoos without having leamed

anything meaningful about the animals' natural behavior, intelligence, or beauty. Zoos keep animals in small

spaces or cages, and most signs only mention the species' name, diet, and natural range.

     The animals' normal behavior is seldom noticed because zoos don't usually take care of the animals' natural

needs. The animals are kept together in small spaces, with no privacy and little opportunity for mental and

physical exercise. This results in unusual and self-destructive behavior called zoochosis. A world-wide study

of zoos found that zoochosis is common among animals kept in small spaces or cages. Another study showed

that elephants spend 22 percent of their time making repeated head movements or biting cage bars, and bears

spend 30 percent of their time walking back and forth, a sign of unhappiness and pain.

     Furthermore, most animals in zoos are not endangered. Captive breeding (圈养繁殖) of endangered big

cats, Asian elephants, and other species has not resulted in their being sent back to the wild. Zoos talk a lot

about their captive breeding programs because they do not want people to worry about a species (物种) dying

out. In fact, baby animals also attract a lot of paying customers. Haven't we seen enough competitions to name

baby animals?

     Actually, we will save endangered species only if we save their habitats and put an end to the reasons people

kill them. Instead of supporting zoos, we should support groups that work to protect animals' natural habitats.
