[简答题]Every new thought or idea has to be connected to what we already know. Unfortunately, it is easy to limit the possibilities of a new idea by connecting it to only one area of our previous knowledge. Great thinkers are aware of this and try to combine new and old ideas in as many different ways as possible. They also try to make connections that may seem strange at first. By comparing and connecting ideas and objects in new ways, creative thinkers are able to think of new applications and solutions. Many of the things that we use every day were invented by someone who saw similarities between his or her ideas and objects or systems in the world.

[简答题]Now, a new idea has been put forward which will utilize areas which have no other obvious commercial potential. These are the ponds, small lakes, disused docks and other areas of water, many of which can be found near, or even in the suburbs of big towns. A new style of construction has been designed which will provide a house for less than half the cost of the conventional building. The main saving is, of course, the land, because the new houses will float on water. There will be no need for foundations; instead the house will be built on a frame made of steel which is expected to cost about ￡ 5 000. Above this the builders will make a house with two, three or four bedrooms and all the usual modern conveniences, as well as a roof garden. Each house will be joined to the main services supplying water, gas and electricity and they will have a vacuum sewage disposal(真空污水处理) system. All the service links will have enough flexibility to allow for small differences in the water level caus

Every living thing has an inner biological clock that controls behavior. The clock works all the time; even when there are no outside signs to mark the passing of time. The biological clock tells plants when to form flowers and when the flowers should open. It tells insects when to leave the protective cocoon and fly away. And it tells animals when to eat, sleep and wake. It controls body temperature, the release of some hormones and even dreams. These natural daily events are circadian rhythms.
Man has known about them for thousands of years. But the first scientific observation of circadian rhythms was not made until 1729. In that year a French astronomer, Jean Jacques d’Ortous de Mairan, noted that one of his plants opened its leaves at the same time every morning, and closed them at the same time every night. The plant did th
A. every creature has an inner biological clock.

C. the biological clock has circadian rhythms.
D. the biological clock regulates behavior of creatures.

[简答题]Every human society has its own particular culture, or sociocultural system, which overlaps to some extent with other systems. Variation among sociocultural systems is attributable to physical habitats and resources; to the range of possibilities inherent in various areas of activity, such as language, rituals and customs, and the manufacture and use of tools, and to the degree of social development. Adaptation and change take place within and among cultures by means of ecological and environmental changes.

A Biological Clock

Every living thing has what scientists call a biological clock that controls behavior. The biological clock tells (1) when to form flowers and when the flowers should open. It tells (2) when to leave the protective cocoons and fly away, and it tells animals and human beings when to eat, sleep and wake.
Events outside the plant and animal (3) the actions of some biological clocks. Scientists recently found, for example, that a tiny animal changes the color of its fur (4) the number of hours of daylight. In the short (5) of winter, its fur becomes white. The fur becomes gray brown in color in the longer hours of daylight in summer.
Inner signals control other biological clocks. German scientists found that some kind of internal clock seems to order birds to begin their long migration (6) twice each year. Birds (7) flying become res
