20世纪50年代在婆罗洲的许多雅克人身患疟疾，世界卫生组织采取了一种简单的也是直截了当的解决方法：喷洒DDT。蚊子死了，疟疾也得到了控制。可是没多久，大范围的后遗症出现了。由于DDT同时还杀死了吃屋顶茅草的毛虫的天敌──小黄蜂，导致人们的房屋纷纷倒塌。同时，DDT毒死的虫子后来成为壁虎的粮食，壁虎又被猫吃掉，DDT无形中建立了一种食物链，对猫造成杀伤力，猫数量的减少又导致了老鼠的大量繁殖。在有可能大规模爆发斑疹伤寒和森林鼠疫的危险时，世界卫生组织只得被迫向婆罗洲空降14 000只活猫，英国皇家空军执行了一次奇特的任务──“降猫行动”。

（1）蚊子属于昆虫，昆虫身体由________、_______、______三部分构成。

（2）在壁虎和老鼠这两种生物中，________属于恒温动物。

（3）从资料中可以看出：蚊子作为食物链或食物网中的某一环节出了问题，就会影响到整个生态系统，可见动物在维持__________中起重要作用。

（4）20世纪60年代，美国生物学家蕾切尔·卡逊女士发表了一份震惊全美国的报告，并写了一本名为____的书，她向美国总统及国民提出警告：DDT等化学药品的滥用已经引发了生态和健康的灾难，连雀鸟也被毒害，鸟的歌声也听不到，春天变得寂静。（填字母）

     阅读下面短文并回答问题(请注意问题后的词数要求)。

    [1] Imagine walking up to a world where China is the

world's leading superpower, astronauts are busy walking on

Mars and a brand new political party is ruling the UK? Well,

this could be the reality in 13 years if some of the predictions of

100,000 Britons are correct.

   [2] The survey asked the people of the UK how they

pictured the world in 2025.

   [3] Nearly half believe Prince William will be crowned

King of England instead of Prince Charles although one in six

think the monarchy ( 君主制度) will have been abolished. A

quarter of those surveyed believe a new party will form the

government in 2025, although the same number of people think

that labour will be back in power.

    [4] On the world stage 60 per cent think China is set to

become the world's leading superpower, while a third think

Great Britain will be made up of four self-governed countries.

     [5] Meanwhile technology will have come on in leaps and

bounds. Four percent are optimistic that there will be a

permanent human base on Mars while one in ten expect a

colony of humans to be living in space. More than half

questioned in the MSN study predict people will watch all their

favorite shows via TV sets hooked up to the Internet. Two-

thirds believe cosmetic surgery ( 整容手术) will have become

common and one in six think we will look after our own health

using computers rather than _                .

    [6] But at least we can amuse ourselves with the daily

comings and goings of pop singers and reality stars, as more

than half think that "celebrity"  ( 明星) will be a registered

profession.
