精英家教網 > 高中英語 > 題目詳情

    Pieter Hoff retired from the flower export business seven years ago. Now, he is trying to help people grow trees and plants in the desert—and save water.

    In many places, much of the freshwater supply is used for irrigation. Yet most of that water may be lost through evaporation(蒸發) into the air. So Pieter Hoff has invented a simple plastic device called the Groasis Waterboxx. He says “If you look at nature, and I give an example, if you look to the Rocky Mountains, you find trees all over the mountains. So trees are actually able to grow on rocks. They have very strong roots. ”

    He says the trick is that nature does not dig a hole like we humans do to plant seeds. Nature plants the seeds through birds or animals on top of the soil. Their waste then acts as a cover. It prevents the humidity(濕度) in the soil from evaporating. The Dutch inventor says he is simply copying that system.

    Some people call the Waterboxx a water battery. The cover has deep ridges. These collect rainwater. But the device is designed to collect water even when there is no rain. The cover gets cold during the night and creates condensation(凝結).

    The water is collected through two holes through which water is carried to the soil. Pieter Hoff says the nice thing is that, once collected, the water is not able to evaporate anymore.

    The roots of the plant may have to grow several meters deep to reach groundwater. Once growth is established, the box can be removed and used to start another planting.

    Pieter Hoff says he is now doing experiments with twenty thousand Waterboxxes in countries including Pakistan, Ecuador and the United States. The reusable box now sells for about fifteen dollars.

64. The reason why Pieter Hoff invented the Groasis Waterboxx is probably that he tried to _______ .

A. solve the problem of evaporation

B. provide freshwater in the desert

C. do experiments with the Waterboxx

D. irrigate more trees and flowers

65. Pieter Hoff got his idea of inventing Groasis Waterboxx by _______ .

A. doing the flower export business

B. carrying fresh water for irrigation

C. studying the system of nature’s planting seeds

D. collecting water when there’s no rain

66. According to Paragraphs 2 and 3, Pieter Hoff actually means _______ .

A. you can find trees on the Rocky Mountains

B. most fresh water is used to water plants

C. nature can save water by itself

D. humans dig holes to plant seeds

67. According to the passage, we can infer the Waterboxx _______ .

A. is needed before the roots of plants come out

B. cannot create condensation through its cover

C. sells well in many countries

D. can only be used once

  本文講述了Pieter Hoff發明的the Waterboxx將有助于在沙漠中種樹。

64.解析:選A。細節理解題。根據第二段可知,沙漠中大部分的水分是被蒸發的,所以Pieter Hoff發明the Waterboxx的初衷是解決這一難題,故選A項。

65.解析:選C。細節理解題。根據第三段第二、三、四句的“Nature plants the seeds. . . in the soil from evaporating. ”可知他是通過研究大自然中植物播種的原理才產生發明的靈感。

66.解析:選C。段落大意題。在第三段中,Pieter Hoff 解釋了他這一發明的由來:他是從大自然的運行中得出靈感的,大自然可以自己蓄水灌溉植物。

67.解析:選A。推理判斷題。根據文章內容可推知,只有當植物在地下扎根后,才可以將the Waterboxx拿走進行重復使用,以幫助其他植物生長;且the Waterboxx目前仍在試驗,并未提及暢銷一事。故只有A項正確。

  Peter the Great(1672 1725)wanted his city to be unique(獨特的)in Russia.So he filled it with canals like those of Venice, baroque(巴洛克式的)palaces and British townhouses.Now the city has celebrated its 300th anniversary(周年紀念).

  Naming the city was a difficult matter.At first, Peter the Great called his huge ambitions new Russian city Sankt Pieter Burkh.But, he soon changed this to St Petersburg.When World WarⅠbroke out in 1914, it was renamed Petrograd.On the death of Lenin in 1924, it became Leningrad.After the fall of the Soviet Union in 1991, it returned to St Petersburg.Many people call it plain Peter today.This seems appropriate given that “petra” means stone(in Russian and Latin)and there was a time when all of Russia's available(可用的)stones were sent there to build Peter's magnificent(雄偉的)“Window on the West”.

  From the start, StPetersburg was a very modern, international city.It first became the Russian capital in 1712 and, with this in mind, Peter hired a great deal of international talent to build and develop it.

  The most obvious effect of this arrival of foreigners was in the layout(設計)of the city's streets, parks, palaces and government buildings.Although bombed to near destruction by Adolf Hitler's forces in the 1940s, the city was rebuilt, stone by stone.What you see around you in the end of Catherine the Great's reign(統治)in 1796 when, after nearly a century, Peter's city was one of the finest in the world.

  Peter the Great's city was, and now remains? a meeting point for the cultures of Russia and Europe, whether you are one of the 49 percent of its population who, in 1991, voted to remain its revolutionary name, Leningrad, or the 51 percent who opted for St Petersburg.To everyone, it remains Peter, an architectural stone of race and fancinating beauty.

Pieter Hoff used to export lilies and tulips from the Netherlands. He retired from the flower export business seven years ago. Now, he is trying to help people grow trees and plants in the desert -- and save water. In many places, much of the freshwater supply is used for irrigation. Yet most of that water may be lost through evaporation into the air. So Pieter Hoff has invented a simple plastic device (設備)called the Groasis Waterboxx. He says he got the idea from nature.

Mr. Hoff says the trick is that nature does not dig a hole like we humans do to plant seeds. Nature plants the seeds through birds or animals on top of the soil. Their waste then acts as a cover. It prevents the humidity in the soil from evaporating(蒸發).

The Dutch inventor says he is simply copying that system. The Waterboxx is a round device about the size of a motorcycle tire. It sits flat on the ground with the bottom open to the earth. Seeds or a young planting grow out of a hole in the center.

Some people call the Waterboxx a water battery because of its ability to collect and store water.

The cover has deep ridges. These collect rainwater. But the device is designed to collect water even when there is no rain. The cover gets cold during the night and creates condensation.

The water is collected through two holes and in the holes there is a siphon to carry it to the soil. Pieter Hoff says the nice thing about the siphons is that, once collected, the water is not able to evaporate anymore.

The roots of the plant may have to grow several meters deep to reach groundwater. Once growth is established, the box can be removed and used to start another planting. The company also makes a version for one-time use.

Researchers at Mohammed the First University in Oujda, Morocco, tested the Waterboxx for three years in the Sahara. They said close to ninety percent of the trees planted with the device survived. Without it, they said, only about ten percent survived.

Groasis Waterboxx---a device to help plant trees in ___1____

How was it invented?

The inventor got inspiration(靈感) from __2____.

What does it look like?

A round device as ___3___ as a motorcycle tire. It can be put ___4___on the ground with a hole at the ___5____.

How does it work?

 

 

Water can be ___6____ and ___7___ through the device. A siphon is used to carry the water to the ___8___. The device can be __9____ away when the plant grows deep enough to get groundwater. and some can only be used for __10____.
