17、s of temperature and pressure commonly found at the surface of the Earth. A liquid can be kept in an open container and (2)_it to the level of a free surface. A gas forms no free surface but (3)_to diffuse throughout the space available; it must (4)_be kept in a closed container, as (5)_a planets at

18、mosphere. The distinction was a prominent feature of early theories (6)_ the phases of matter. In the nineteenth century, for example, one theory maintained that a liquid could be dissolved in a vapor without losing its identity, and another theory held that the two phases are (7)_different kinds of

19、 molecules(分子). The theories now prevailing (8)_a quite different approach by emphasizing what liquids and gases have in common. They are both forms of matter that have no permanent structure, and they both flow easily. They are fluids. The (9)_similarity of liquids and gases becomes clearly apparen

20、t when the temperature and pressure are raised somewhat. (10)_a closed container partially filled with a liquid is heated. The liquid expands, or (11)_, becomes less dense; some of it evaporates. (12)_, the vapor above the liquid surface becomes denser as the evaporated molecules are added to it. Th

21、e combination of temperature and pressure (13)_the densities become equal is (14)_ the critical point. Above the critical point the liquid and the gas can no longer be (15)_; there is a single, undifferentiated fluid phase of uniform density.（分数：1.05）A.inB.onC.underD.beyondA.fillsB.be filledC.fillin

38、thin a group. These scientists, however, are cautious about the extent to which animals can be credited with conscious processing. Explanations of animal behavior that leave out any sort of consciousness at all and ascribe actions entirely to instinct leave many questions unanswered. One example of

39、such unexplained behavior: Honeybees communicate the sources of nectar to one another by doing a dance in a figure-eight pattern. The orientation of the dance conveys the position of the food relative to the suns position in the sky, and the speed of the dance tells how far the food source is from t

40、he hive. Most researchers assume that the ability to perform and encode the dance is innate and shows no special intelligence. But in one study, when experimenters kept changing the site of the food source, each time moving the food 25 percent farther from the previous site, foraging honeybees began

41、 to anticipate where the food source would appear next. When the researchers arrived at the new location, they would find the bees circling the spot, waiting for their food. No one has yet explained how bees, whose brains weigh four ten-thousandths of an ounce, could have inferred the location of th

42、e new site. Other behaviors that may indicate some cognition include tool use. Many animals, like the otter who uses a stone to crack mussel shells, are capable of using objects in the natural environment as rudimentary tools. One researcher has found that mother chimpanzees occasionally show their

43、young how to use tools to open hard nuts. In one study, chimpanzees compared two pairs of food containing chocolate chips. One pair might contain, say, five chips and three chips, the other four chips and three chips. Allowed to choose which pair they wanted, the chimpanzees almost always chose the

44、one with the higher total showing some sort of summing ability. Other chimpanzees have learned to label quantities of items and do simple sums. （分数：1.00）(1).Which of the following is NOT discussed as an ability animals are thought to have?（分数：0.20）A.Selecting among choices.B.Anticipating events to c

45、ome.C.Remembering past experiences.D.Communicating emotions.(2).What is the purpose of the honeybees dance?（分数：0.20）A.To determine the quantity of food at a site.B.To communicate the location of food.C.To increase the speed of travel to food sources,D.To identify the type of nectar that is available.(3)
