Not only does it allow greater of the plant growth process, it permits the production of cro

9、ps in hostile infertile environments.The first widely publicized soilless gardening experiments were conducted during the 1930s. W. F. Gericke varied nutrient levels among specimens suspended in a gravel substrate (沙砾基质) to demonstrate remarkable alterations in growth. Among the findings that amazed

10、 his fellow horticulturists was the production of tomato plants over 6 meters high.The original hydroponics gardens merely consisted of plants floating in water. It was later discovered that the roots could survive in a number of media, as long as they were supplied with sufficient moisture, nutrien

11、ts and oxygen. A variety of materials are used in recent versions including gravel, sand, peat, sawdust, plastics and so on. Indeed, one of the most productive methods involves suspending plants in air with a Styrofoam support and spraying them occasionally with nutrient solution to keep them moist.

12、Many different kinds of materials are suitable for physically containing plants, yet all of these systems share one trait: the culture solution. This nutrient bath is prepared in a tank by dissolving salts which provide the necessary chemicals for plant metabolism. Constant care must be taken to ass

13、ure that the sodium chloride(氯化纳)levels in the tank do not reach excessive levels as the plants draw water and minerals out of the solution. The acidity of the tank must also be maintained around 6.0 to 6.5 depending on the specific type of plants being harvested.Although soilless farming is general

19、 after centuries of scientific research, no one knows for sure why human beings (plus a few other primates, including chimpanzees, apes, and orangutans) laugh.2. Even if scientists still do not know why we laugh, they have learned a lot about it. For example: The sound of laughter is created when yo

The typical laugh is made up of pulses of sound that are about 1/15th of a second long and 1/5th of a second apart.3. One of the most interesting things researchers have learned is the p

21、owerful healing effect of laughter. Well, actually they re re-learning it after centuries of neglect: In the Middle Ages, doctors “treated“ their patients by telling them jokes, but modem medicine discounted the curative properties of laughing. That began to change in 1979, when editor Norman Cousin

22、s wrote Anatomy of an Illness, in which he credited watching humorous videos with helping him reduce pain and recover from ankylosing spondylitis (类风湿性脊椎炎), a lifethreatening degenerative spinal disease. The book inspired researchers to look into whether laughter really could aid in healing and reco

31、的问题，从 4个选项中选择 1个最佳答案。B第一篇/BIn an average winter, highway departments spread some ten million tons of salt to keep roads safe. The corrosive effects are well known, but for years they re been dismissed with the argument that at around $ 25 a ton, salt is far cheaper than any alternative.Lately, econo

32、mists have added up the actual costs. The Environmental Protection Agency estimates that salt-induced road damage and vehicle corrosion cost $ 3 billion a year. That does not include damage to underground cables, which adds hundreds of millions to utility bills. Nor does it reflect the cost of brine

33、 leaking into porous water pipes, threatening the water supply. Salty water leaches into roadbeds, kills evergreens and poisons streams.The various costs probably add another $ 2 billion to the national salt bill. Scientists estimate the full economic, or “life cycle,“ cost for a ton of salt at $ 50

34、0, or 20 times the $ 25 purchase price. That begins to make the switch to calcium magnesium acetate, perhaps the most promising alternative look practical. CMA, made from acetic acid and dolomitic(含白石的) lime, costs $ 600 a ton and has minimal adverse effect. Some researchers believe the cost can be

35、halved by making CMA from waste cheese whey or pulp-mill effluent.While CMA and other alternatives are being researched, many cities and states are cutting back on their use of salt. Keeping dispensing equipment in good repair helps reduce the amount spread.（分数：15.00）(1).Salt spread on road in winte

36、r may cause all the following problems except _.（分数：3.00）A.road damageB.vehicle corrosionC.damage of underground cablesD.car accident(3).Why is CMA favoured to salt? Because _.（分数：3.00）A.it is less expensiveB.it has minimal adverse effectC.people like it better than saltD.highway departments want to

37、 have a change(4).In the last sentence, “the amount“ is referred to that of_.（分数：3.00）A.CMAB.saltC.other alternativesD.either of the above(5).According to the author, when can CMA be applied to the road?（分数：3.00）A.In the near future.B.Right now.C.After its cost halved.D.Cannot tell from the passage.

38、B第二篇/BAfter the violent earthquake that shook Los Angeles in 1994, earthquake scientists had good news to report: The damage and death toll could have been much worse.More than 60 people died in this earthquake. By comparison, an earthquake of similar intensity that shook America in 1988 claimed 25,

39、000 victims.Injuries and deaths were relatively less in Los Angeles because the quake occurred at 4:31 a. m. On a holiday, when traffic was light on the citys highways. In addition, changes made to the construction codes in Los Angeles during the last 20 years have strengthened the citys buildings a

40、nd highways, making them more resistant to quakes.Despite the good news, civil engineers arent resting on their successes. Pinned to their drawing boards are blueprints for improved quake - re - sistant buildings. The new designs should offer even greater security to cities where earthquakes often t

41、ake place.In the past, making structures quake-resistant meant firm yet flexible materials, such as steel and wood, that bend without breaking. Later, people tried to lift a building off its foundation, and insert rubber and steel between the building and its foundation to reduce the impact of groun

42、d vibrations. The most recent designs give buildings brains as well as concrete and steel supports. Called smart buildings, the structures respond like living organisms to an earthquakes vibrations. When the ground shakes and the building tips forward, the computer would force the building to shift

43、in the opposite direction.The new smart structures could be very expensive to build. However, they would save many lives and would be less likely to be damaged during earthquakes.（分数：15.00）(1).One reason why the loss of lives in the Los Angeles earthquake was comparatively low is that _.（分数：3.00）A.n

44、ew computers had been installed in the buildingsB.large numbers of Los Angeles residents had gone for a holidayC.it occurred in the residential areas rather than on the highwaysD.improvements had been made in the construction of buildings and highways(2).The function of the computer mentioned in the

45、 passage is to_.（分数：3.00）A.measure the impact of an earthquakes vibrationsB.help strengthen the foundation of the buildingC.predict the coming of an earthquake with accuracyD.counterbalance an earthquakes action on the building(3).The smart buildings discussed in the passage _.（分数：3.00）A.can reduce

46、the ground vibrations caused by earthquakesB.would be worthwhile though costlyC.would not be worthwhileD.would cause serious financial problems(4).It can be inferred from the passage that in minimizing the damage caused by earthquakes attention should be focused on _.（分数：3.00）A.the increasing use of

47、 rubber and steel in capital constructionB.the reduction of the impact of ground vibrationsC.the development of flexible building materialsD.early forecasts of earthquakes(5).The authors main purpose in writing this passage is to_.（分数：3.00）A.compare the consequences of the earthquakes that occurred

48、in the U. S.B.outline the history of the development of quake- resistant building materialsC.report new developments in constructing quake - resistant buildingsD.encourage civil engineers to make more extensive use of computersB第三篇/BSince about 1970, new research has helped brain scientists understands these problems better. Scientists now know there are many different kinds of learning disabilities and that they are caused by many different things. There is no longer any question that all learning disabilities result from differences in the way the brain is organized. You can t look at a ch
