When you are under water, it is easy for you to climb big rocks, because you are no longer heavy.Here, under water, everything is blue and green. During the day, there is plenty of light. When fish swim nearby, you can catch them with your hands.When you have tanks of air on your back, you can stay in deep water for a long time. But you must be careful when you dive in deep water.To catch fish is one of the most interesting parts of this sport. Besides, there are more uses for skin-diving. You can clean ships without taking them out of water. You can get many things from the deep sea.Now you see that skin-diving is both useful and interesting.In formation CardA new sport today81.___________

考题 Passage FourArchimedes was a famous Greek mathematician and scientist. He was born around 287 BC and he died in the year 212 BC.Archimedes is most well-known for one specific idea that he came up with. "Archimedes's Principle" states that a solid object which is immersed in a liquid is pushed up by a force which is equal to the weight of the water that the object moves. For example, if you put a piece of wood and a piece of gold the same size in water, only the wood will float. Both the wood and gold move the same amount of water, but the wood weighs less than this water, while the gold weighs more.It is believed that Archimedes discovered this principle when the king of Syracuse asked him to solve a problem. The king wanted to know if his crown was pure gold or a mixture of gold and silver. The king, of course, did not melt his crown to find out. The idea came to Archimedes as he lowered himself into his bath. He noticed how the water spilled out of the tub. He decided to use the same idea for the crown. He knew that a gold crown immersed in water would weigh more than one made of silver. The experiment was done and the goldsmith was proved guilty of trying to cheat the king.48. A good title for the selection is______.A. ArchimedesB. Archimedes's PrincipleC. A Gold and Silver CrownD. The King of Syracuse

考题 Once a week my aunt would announce, "I am going to have my bath today."Now most people find it fairly simple to have a bath.You probably remember how it goes.You enter the bathroom, you put the plug in, turn on the hot water, get into the bath, wash, sing, get out, dry yourself and exit.My aunt's approach was more epic(宏大的), like one of those long Eisenstein films where people seem to be climbing up the same flight of stairs forever.My aunt would first slowly collect her clean linen(亚麻布衬衫), so as to have it all ready for changing into after her bath.This involved sorting out her linen, which took up most of the morning.Sometimes she would find an old letter buried among her linen, become interested in the memories it aroused and have to postpone the bath until the next day.But if all went well, she would have a bite of lunch and start Phase Two around two o'clock.Phase Two was washing out the bath.She would wash the bath very thoroughly, rinse(冲洗) it with running cold water, rewash it and then carefully feel the whole surface with her fingers.If there was the slightest blemish, she would clean the whole bath out again.This took about an hour.Then she would fill the bath.By this time she was feeling a bit hungry and exhausted.So she would put on the kettle for a cup of tea.Several cups of tea and several cream crackers (her favourite food) later, she would go back to the bathroom.And find the water stone cold.1.According to the writer, most people().A.read magazines in the bathB.make bath time a special occasionC.sing when they are in the bathD.have a bath once every other week2.The writer's aunt().A.never got used to taking a bath regularlyB.always treated bathtime as an eventC.hated climbing the stairs to the bathroomD.would collect her new linen quickly3.How did she use to spend most of the morning?()A.Reading old letters.B.Preparing lunch.C.Getting the bath water hot.D.Sorting out her linen.4.Why might the writer's aunt put off bathing until the next day?()A.She might get fascinated by an old letter.B.She would sometimes get too tired.C.She would sometimes have lunch instead.D.She might start ironing the linen.5.She would never fill the bath until she().A.had cleaned it at least three timesB.had had several cups of teaC.had polished it inside and outsideD.had made sure it was perfectly clean

考题请阅读短文，完成此题。 When we analyze the salt salinity(盐溶度 ) of ocean waters, we find that it varies only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation. In this manner, the salinity is increased, since the salt stays behind. If this is carried to the extreme, of course, white salt would be left behind; this, by the way, is how much of the table salt we use is actually obtained. The opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. Here the ocean is being diluted so that the salinity is decreased. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by-evaporation, or decreased by the addition of fresh water by precipitation. Normally, in hot regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas. A third process by which salinity may be altered is associated with the formation and melting of sea ice. When seawater is frozen, the dissolved materials are left behind. In this manner, seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water. In the Weddell Sea, the densest water in the ocean is formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portion of the oceans of the world. The purpose of mentioning the Weddell Sea is__________. 查看材料 A．to give an example of cold-water salinity B．to point out the location of deep waters C．to make a comparison between hot-water salinity and cold-water salinity D．to show that the water in the Weddell Sea varies in salinity from place to place

The main benefits（or advantages）of cold-water swimming are probably mental.The Polar Bears love to swim year-round;they find it fun and relaxing.As one 70-year-old woman says,"When I go into the water,I pour my troubles into the ocean and let them float away."
