| 第3题：Ocean water plays an indispensable role in supporting life. The great ocean basins hold about 300 million cubic miles of water. From this vast Line amount, about 80,000 cubic miles of water are (5) sucked into the atmosphere each year by evapora- tion and returned by precipitation and drainage to the ocean. More than 24,000 cubic miles of rain descend annually upon the continents. This vast amount is required to replenish the lakes and (10) streams, springs and water tables on which all flora and fauna are dependent. Thus, the hydro- sphere permits organic existence. The hydrosphere has strange characteristics because water has properties unlike those of any (15) other liquiD、One anomaly is that water upon freezing expands by about 9 percent, whereas most liquids contract on cooling. For this reason, ice floats on water bodies instead of sinking to the bottom. If the ice sank, the hydrosphere would (20) soon be frozen solidly, except for a thin layer of surface melt water during the summer season. Thus, all aquatic life would be destroyed and the interchange of warm and cold currents, which moderates climate, would be notably absent. (25)Another outstanding characteristic of water is that water has a heat capacity which is the highest of all liquids and solids except ammoniA、This characteristic enables the oceans to absorb and store vast quantities of heat, thereby often pre- (30) venting climatic extremes. In addition, water dis- solves more substances than any other liquiD、It is this characteristic which helps make oceans a great storehouse for minerals which have been washed down from the continents. In several (35) areas of the world these minerals are being com- mercially exploiteD、Solar evaporation of salt is widely practiced, potash is extracted from the Dead Sea, and magnesium is produced from sea water along theAmerican GulfCoast. Which of the following characteristics of water does the author mention in the passage Ⅰ. Water expands when it is frozen. Ⅱ. Water is a good solvent. Ⅲ. Water can absorb heat.A．Ⅰ only B．Ⅱ only C．Ⅰ and Ⅱ only D．Ⅱ and Ⅲ only E、Ⅰ, Ⅱ, and Ⅲ |

| 第4题： Which of the following hypothetical scientific discoveries, if made, would weaken the author's arguments concerning the ethical risks of human cloning A．Through careful and documented study, cloning proves to be less risky than consanguineous breeding. B．A laboratory process for reducing the number of stages in the cell division process is developed. C．A non-cloning method for curing human fertility is discovered, thereby reducing the need to rely upon cloning. D．A procedure for easing the acclimation of a foreign nucleus in the embryonic host is established. E．(E) A means of assessing genetic mistakes in a foreign nucleus before its implementation into a clone is devised. |
