实验题

仔细阅读以下材料,分析并回答下列问题。

材料一:随着“江北水域”积极推进“生态城市”的建议,生态环境得到了进一步的改善。每到冬季来临之前,东昌湖又见野鸭归来。誉有“喜鹊之乡”的东阿县鹊巢星罗密布,鹊声悦耳动听,已成为一道亮丽的风景线。 

材料二:蚕农发现,雌雄蛾从茧中钻出来,必须在很短的时间内爬到一起交配,否则,因寿命短暂会失去传种接代的机会。雌雄蛾能在较短的时间内爬到一起,完全是靠它们之间释放的“气味”和闻到“气味”实现的。 

材料三:随着人类对野生动物保护意识的增强和对动物行为研究工作的深入,人们发现很多野生动物在人工饲养条件下一些重要行为的丢失,如野马只会在水槽中饮水。为了恢复野马在野生条件下饮水能力,把原先导水入槽的橡胶管拉向水坑,一步步诱导野马去水坑饮水,从而恢复野马的野外生存能力。 

(1)材料一中列举了2种生物的不同行为,即野鸭的________行为和喜鹊的繁殖行为。从动物行为获得途径看,它们应属于_____________行为,这种行为是由动物体内的遗传物质决定的。

(2)材料二中的雌雄蛾依靠“气味”爬到一起,这种“气味”在生物学上叫做性外激素,这一实例表明了动物个体之间能够进行_____________。

(3)材料三中的人类对野马进行野外饮水训练,野马所形成的水坑饮水行为属于____________,这种行为是在遗传因素的基础上,通过_________因素的作用,由生活经验和学习获得的行为。

     Working at home is increasing in popularity as a means of escaping from nine-to-five office life. Why

work under the constant watch of your boss when you can work in front of the TV in your carpet slippers?

Armed with all the office essentials-telephone, computer, e-mail and fax, many workers believe they can

work as effectively as their colleagues in the office. Being able to work wherever you like: from a busy city

to a beautiful village, and make working from home an attractive choice, you can even work on a canal boat,

like one Internet firm in the Midlands, US.

     So what will become of the office of tomorrow? I believe it is likely that many could disappear into

cyberspace. To minimize office overheads in inner-city areas, companies will apply a workforce made up

of a network of home workers linked by an advanced communication and information system. A central

processing computer would be controlled by the manager who sends'out work schedules and oversees the

activity of each employee.

     As a successor to the Web Cam, a video screen would be created, as the need for more natural form

of interaction than e-mail or telephone becomes greater. Capturing the mood and expressions of work

colleagues, managers would have the ability to view several employees at once on their screen. Employees

would be encouraged to feed any information that may be useful to fellow workers into the computer to

make the company work more effectively. As the company's life blood, the computer would contain a

record of all conversations and correspondence for future reference, and hold confidential information such

as accounts in password protected areas. In the office of tomorrow, with daily life captured in detail, the

case for firing employees could be more cleat cut.
