高一英语单项填空中等难度题查看答案及解析

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

C. if dead leaves decay in the soil by themselves  D. if waste plant material lying about is buried

2.We can learn from the passage that the tired land has slowly recovered (   )

A. when grasses and other plants appear again

B. when the treatment is given by nature alone

C. after new grasses and other plants have decayed again

D. after nature has been left alone for several months

3.A modern farmer can hardly move to another place as he did before because (   )

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

4.It is most likely that the author will go on to (   ) in the paragraph following the passage above.

A. introduce other methods of planting crops     B. deal with how to prevent land getting tired

C. start another topic of how to make use of land  D. further explain what the rotation of crops is

Four wild young pandas were found at different times walking around with their mothers in a nature reserve in northwestern China in recent months, a report said on Sunday. Infrared (红外线的) cameras in Baishuijiang National Nature Reserve in Gansu Province caught four young pandas following their mothers and learning survival skills, such as feeding themselves, in the first quarter of 2019.

It was the latest finding of new young pandas in the area, which has the largest population of wild pandas among China’s 67 nature reserves. The fourth national survey on pandas, released in 2015, said there were 110 wild pandas living in the Baishuijiang area. A total of 1,864 lived in China.

The Baishuijiang National Nature Reserve has used infrared cameras since 2012 to monitor pandas, but this is the first time that four pairs of pandas have been found. “In the past, we found one pair every quarter at most,” said He Liwen, director of the Baishuijiang reserve. The young pandas’ body sizes suggested that two of them were a year and a half old, while the other two were almost 2 years old.

“The four pairs were caught in different places far away from each other. It’s very easy to see the differences,” he said. “So we can be sure of the number. “Baishuijiang staff members also found rare wildlife, including golden monkeys, Asian golden cats and gazelles.

The reserve director attributed (把……归因于……) the good news to the government’s hard work and local people’s efforts to protect the natural habitat over many years. “It’s a process of continuous, growing progress,” he said.
