For each question or statement there are 4 choices marked A, B, C, and D. You should make the correct choice. 55 There are many reasons for tidal action; thus, tides are very
25、 complicated phenomenon involving many factors, all of which must be considered to predict tidal action in any one place at any given time. The alternate rise and fall of the surface of the seas and the oceans is mainly caused by the attractive force of the moon. When the attraction is great, the ti
26、de is high; conversely, when the attraction is minimal, the tide is low. Between the high tide and the low tide is a period of a little over six hours, being called during its rise a flood tide, and during its fall an ebb (退潮 ) tide. The sun also exerts its effect on the tide, being a little less th
27、an half as much as the moon, although its mass is so much greater. When the moon and the sun are horizontal, the highest tide occurs and when they are vertical the lowest tide takes place. The wind also plays an important part in the modification of the normal rise and fall of the tides. Thus these
28、factors affect each other, either detracting (转移 ) or adding to the attractive forces to add or subtract from the magnitude of the tide. One thing is certain: the tides move inexorably (不可阻挡 ) on, rising twice a day, shifting a little in time each day, and coutinually posing the problem of how to co

40、ace of the seas （ D） does not influence the rise and fall of the surface of the seas Task 2 Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45. 65 For many years, scientists couldnt figure out how atoms and molecules combined to make livi
41、ng things. Plants, fish, dinosaurs, and people are made of atoms and molecules, but they are put together in a more complicated way than the molecules in the primitive ocean. Whats more, living things have energy and can reproduce, while the chemicals on the Earth 4 billion years ago were lifeless.
42、After years of study, scientists figured out that living things, including human bodies, are basically made of amino acids, nucleotide bases, lipids and water. How could such complicated molecules have been formed and have started to interact in the primitive soup? Scientists were stumped. Then, in
43、1953, two scientists named Harold Urey and Stanley L. Miller did a very simple experiment to find out what had happened on the primitive Earth. They set up some tubes and bottles in a closed loop, and put in some of the same gases that were present in the atmosphere 4 billion years ago water vapour,
44、 ammonia, carbon dioxide, methane, and hydrogen. Then they shot an electric spark through the gases to simulate bolts of lightning on the ancient Earth, circulated the gases through some water, sent them back for more sparks, and so on. After several days, the water that the gases had been bubbling
45、through turned brown. Some new chemicals were dissolved in it. When Miller and Urey analyzed the liquid, they found that it contained amino acids the very kind of molecules found in all living things. 65 When did scientists come to realize how the atoms and molecules on the Earth mostlikely combined
46、 to make living things? （ A） 4 billion years ago. （ B） After seven days. （ C） Many years ago. （ D） In 1953. 66 Scientists figured out that human bodies are basically made of _. （ A） hydrogen, carbon, nitrogen, and oxygen atoms （ B） water vapor, ammonia, carbon dioxide, methane and hydrogen （ C） biom

Miller did their experiment in order to _. （ A） dissolve some new chemicals （ B） find out what may have happened on the Earth 4 billion years ago （ C） simulate bolts of lightning on the ancient Earth （ D） analyze a liquid 6
