When nature is left alone, a balance is reached among the animals and plants living in one area. But when man starts his work in nature, the balance is likely to be destroyed. He grows a crop and takes it away to eat ;then there are no dead leaves to fall on the ground, holding water while it sinks into the surface, or decaying (腐烂) and adding humus (腐殖质) to the soil. Unless a farmer acts with knowledge and skill, he is therefore most likely to make the land poorer. To take the place of the useful matter in the crops that he removes, he uses some kind of fertilizer (肥料). Chemical fertilizers are of great help, but the waste products of animals and decaying remains of plants should also be put on the land. In some places, it is a habit to burn waste material lying about, but such burning destroys the useful matter in the dead plants. Although the ashes that are left are valuable when put on the land, a better practice is to bury the waste so that it decays and increases the humus in the soil.
In the past, when the world population was much lower than it is now, a man had little difficulty in ordinary times in growing the food that was needed. When a field had been used some years and had become tired, the farmer could move to another place. The tired land then slowly recovered. By and by grasses and other plants would appear on it and its productive power would slowly return to normal through their decay. But nature, left alone, would take a long time to bring back the land to its former state; the length of time required would depend on local conditions, but it might well be ten years.
It is a bad practice to grow the same crop in a field year after year. If the crop is changed, the land will suffer less because it is treated and used in a different way. Different plants have different effects on the soil. Therefore, a change of crop will do less harm than the growing of the same crop year after year and a regular change to grass will do good to the soil. Much will therefore be gained if different crops are grown one after another, a method known as the rotation (轮作) of crops.
1.According to the passage, the land will become poorer ( )
A. if all the dead leaves are cleared away B. if the humus is increased after the harvest

A. the productive power of a new field isn't higher than that of an old one
B. there are few free fields left for him to do farming
C. it takes a farmer more than ten years to start farming in a new field
D. there will be too many grasses in a new field to grow crops

36. (Part One) Once your plants are growing you will need to keep them happy. How do you do this and what sorts of tools will you need? Plants need water and food, but when and in what sort of quantities? This module explains the cultivation techniques necessary to keep your plants in fine fettle. There are simple basic steps you can take to ensure you cut the right stem, at the right time, in the right place.
37. (Part two) Plants lose water through their leaves all the time. It is essential to ensure there is enough to replenish the roots, otherwise they will die. In warm weather water is lost from the soil by evaporation, so watering will need to be done more often.
38. (Part Three) To keep them growing healthily, plants absorb through their roots about 30 different nutrients and minerals dissolved in water.
39. (Part Four) Pruning is basically cutting off carefully selected parts of a plant to restrict its size, persuade it to grow in a particular shape, encouraging more fruit, flowers or stems, or to remove dead or diseased material. But pruning is neither difficult nor complicated; in fact a lot of it is applying common sense! You just have to follow a few guidelines and check in a book what kind of pruning the particular plant needs. The removal of dead, diseased, broken, crossing and crowded branches is often sufficient for many plants.
40. (Part Five) A spade is your basic digging implement; use it to make holes and to dig sandy or loamy soil. Fork is perfect for digging soil that’s stodgy, such as clay, or full of stones; moving and spreading organic matter; and breaking down clods of soil…

China’s second manned（人造的） space flight will be done by two astronauts（宇航员） over five days in 2005. “Shenzhou-VI will be sent into space sometime in 2005,” said Zuo Saichun, a spokesperson of the China Aerospace Science and Technology (CAST). “The spacecraf
t（宇宙飞船） will make new breakthroughs（突破性进展） in China’s manned space technology.”
Unlike Shenzhou-V, a little more than a year ago (in October, 2003), the next flight will see two astronauts fly in space for five days. Their capsule (太空舱) is designed to be capable（能够）of orbiting（绕轨道运行） for a whole week, the spokesperson said. “For the first time, astronauts will enter and live in the orbital module（舱） of the spacecraft to do scientific experiments,” said a statement from CAST. CAST did not say what those experiments will be.
In Shenzhou-VI, scientists have changed the spacecraft’s configuration (构形) to reduce its weight, and tried to improve the performance of on-board equipment. They have also worked to make sure of the energy supply of the spacecraft and further improve its safety. So far, scientists have worked out ways to solve problems on environmental control and life support. Shenzhou-VI will be sent into orbit atop（在……顶上） a Long March 2F rocket.
Meanwhile, a model of the Chang’e-1 satellite is expected to be sent to orbit the moon in two years. The satellite, part of the three-stage programme, would be followed by the landing of an unmanned vehicle on the moon in the second stage by 2010 and collecting samples（样品） of lunar soil by 2020 in the final stage, according to Sun Laiyan, director of the China National Space Administration.
【小题1】. Which of the following about Shenzhou-VI is NOT true?
A．It will be sent into space in 2005. | B．It is capable of orbiting for two weeks. | C．It will be sent into orbit atop a Long March 2F rocket. | D．It will be sent into space with two astronauts. |
| A．environmental control | B．energy supply | C．life support | D．lunar soil collecting |
| A．Shenzhou-VI’s being sent into space. | B．A model of the Chang’e-1 satellite will be sent to orbit the moon. | C．The landing of an unmanned vehicle on the moon. | D．Collecting samples of lunar soil.  |
| A．some problems need solving before Shenzhou-VI is sent into space | B．Shenzhou-VI will be sent into space in 2005 | C．what China’s space programme is | D．how China’s three-stage programme is carried out |
