One day a mime(哑剧演员) is visiting the zoo and wants to make some money as a street performer. As soon as he starts to draw a crowd, a zookeeper drags him into his office. The zookeeper explains that the zoo’s most popular attraction, a gorilla(大猩猩), has died suddenly and the keeper fears that attendance at the zoo will fall off. He offers the mime a job to dress up as the gorilla. The mime accepts.

The next morning the mime puts on the gorilla suit and enters the cage before the crowd comes. He soon discovers he can sleep all as he likes, play and make fun of the people and he draws bigger crowds than he ever did as a mime — the job he likes but loses.

However, with days going by, he begins to notice that the people are paying more attention to the lion in the cage next to his. Not wanting to lose the attention of his audience(观众), he climbs to the top of his cage, crawls across a partition(隔墙), and dangles(悬挂) from the top to the lion’s cage. The lion gets angry at this. The scene is afuel to the crowd.

At the end of the day he is given a pay raise for being such a good attraction. Well, this continues for some time. The crowds grow larger, and the mime’s pay keeps going up.

Then one day when he is dangling over the lion he slips and falls. The mime is terrified(吓坏). He starts screaming, “Help me!”, but the lion is quick. The mime soon finds himself flat on his back looking up at the angry lion and the lion says, “Shut up you fool! Do you want to get us both fired?”

多项选择题

(九)华氏公司是一家拥有10家火力发电厂,3家电力设备制造厂、8家酒店的集团公司。董事长兼总经理李杰对公司的整体运行和经济效益比较满意,令他忧心的是由于10家电厂均处于不同城市的市区,发电产生的大量粉煤灰没有得到很好的利用,既浪费资源又污染环境,各方面意见较大。经过专利检索,李杰发现一位名叫黄英的女士发明了一种从粉煤灰中提取纳米级空心玻璃微珠的新技术并获得了专利。调查得知,空心玻璃微珠是一种用途广泛的填充材料,能改变金属、橡胶、塑料等材料的性能,用途十分广泛。尤其达到纳米级的微珠,是一种高新技术产品,目前只有美国、德国有此技术。李杰与黄英取得联系,经过谈判,双方商定黄英以专利技术出资与华氏电力公司共同组建一个微珠生产企业,先利用1家电厂的粉煤灰生产微珠,取得成功后扩大到所有电厂。由于该项目投资巨大,李杰聘请了部分专家与董事会成员一起进行了多次研究和论证,并且聘请了一家专业咨询公司,通过从国内外广泛收集资料,用各种数理技术进行了分析、演算,得出了肯定的结论。方案获得通过后,为了使方案更好地实施,李杰决定将8家酒店通过资本市场置换出去,在保留原职能部门的情况下,将公司的主营业务调整为发电、微珠、发电设备制造三大板块,新成立三个部门分别管理这三大板块的生产经营业务。同时,为了充分利用微珠项目的环保、资源再生和纳米技术的高科技性,公司决定加大广告宣传力度,扩大该项目和产品的影响,树立企业形象,争取国家优惠政策,发展潜在客户,利用在可预见的将来产品在市场上的独占性,在产品定价上追求利润最大化,争取尽快收回投资。两年后,华氏电力公司已收回在微珠项目的全部投资,企业进入了快速发展的通道。根据上述资料,回答下列问题:
