They have been working hard to turn this desert green. They came up with many good ideas. First, they planted special trees and plants. These plants have strong roots that can 3 the sand and their leaves can stop the sand from moving. To help the plants grow, people also built a smart water-giving system which is called “drip irrigation”. It works like a tiny water drop falling onto the roots of plants slowly. In this way, the plants get enough water without wasting it. The water-saving method is very important because water is so 4 in the desert.

We can use computers to calculate. They can calculate at a(n) 1 speed than we can and almost never give wrong answers. We can also type and draw things with them. 2 , computers can do important jobs like operating railways and flying spaceships. Is a computer 3 than me? The answer is “No”. Your brain can produce new ideas, but computers cannot. However, one day computers may be able to do a better job than human beings. For example, they may be better than doctors at doing their job.

Precipitation comes down, exactly, everywhere—in different forms. It may rain, hail, or snow. Whatever the form is, once it reaches the ground some water is 1 by trees and other plants. Some water enters the groundwater supply by infiltration. Most water runs off the surface, down a hill and finally into a river. Ditches and small streams may be dry when it does not rain. They can quickly 2 with water when it rains. Once the water finds its way into a stream or ditch, where does it go? If you have ever studied a map in detail, you will notice how rivers and streams form a network of waterways across the countryside. Little streams come together to form small rivers, which then join together and become medium-sized rivers. All these rivers may be branches of a large river, such as the Mississippi. Together, the network of rivers and streams forms a watershed, which drains the land of excess water. This type of pattern is 1 in many places in nature. In the human circulatory system, for example, in human lungs, when you breathe out, your lungs behave just like a 2 . The air in your lungs (which is like the water in a watershed) starts in the smallest vessels (which are like small streams), passing into larger vessels (that are like medium rivers) and finally into one large central air passage (which is like a large river). In the end, all the air in the lungs (which are like a large watershed) passes through this one large air passage, out your mouth, and to the 3 beyond, just as water in a watershed flows out the mouth of a large river and into the ocean!

It hides under mountains, plains (平原) and even 2 . Tiny gaps between rocks and soil 3 and hold this water like a sponge (海绵), which is called aquifers (含水层). Groundwater is a key part of Earth’s water cycle. Some groundwater naturally rises and 4 out onto Earth’s surface through springs (泉). In fact, the amount of groundwater we use is 200 times that of oil. A．directly  B．precious  C． rise  D．up  E. chemicals As human-caused climate change dries out parts of the planet, the need for groundwater will 46 . At the same time, climate change may make storms heavier. Heavier rains are more likely to rush 5 into lakes and rivers than flow into soil. So there may be less groundwater to go around. Meanwhile, human activity pollutes groundwater in many places. Some 6 from farming or mining (采矿) flow into these aquifers. Electronic waste has also polluted groundwater. What can be done? We can cut back on pollution and find new ways to purify (净化) groundwater. What else can you think of to help protect this 7 resource? 四、Complete the passage with the words or phrases in the box (选词或词组完成短文) A．protect      B．ways      C． experienced D．change      E. produced Water is very important for life, yet many countries are facing serious water problems.

About 90 percent of its used water is cleaned and reused for farming. Australians have 3 terrible droughts (旱灾), so now they use special tanks to collect rainwater for daily use. Meanwhile, Singapore has developed technology to 4 seawater into drinking water, reducing its need to buy water from other countries. A．careful      B．quickly      C． enough   D．matters      E. hardly Even small daily habits can make a big difference. For example, turning off the tap while brushing your teeth can save up to six liters of water per minute. Fixing broken pipes 5 stops unnecessary water waste. Some cities, like Tokyo, have reduced water loss by replacing old pipes and encouraging the use of water-saving devices. However, in some places, water is still wasted because people are not 6 or because the water systems are too old. Education plays an important role in changing people’s attitudes towards water use. If everyone takes action, we can make sure that future generations will have 7 water to live well. Saving water isn’t just one country’s problem—it’s something the whole world must care about.

They are incredibly 1 to the health of our planet. However, these forests are in great danger. A recent study published by a famous environmental 2 company shows that large areas of forest are being cut down every day. Often, the trees are cleared to make way for a new 3 or to create farmland. This is a serious 4 backwards for our environment. A．beyond     B．desert     C． snake     D．shoulder     E. spread The loss of trees means many animals lose their homes and must move 5 their original territory (领地) to survive. The harmful influence doesn’t stop there. The carbon dioxide that was stored in the trees is released into the air, which helps to 6 global warming. Sometimes, the land becomes so poor after the trees are gone that it turns into a dry 7 , unable to support life. We cannot just 8 this problem and carry on as before; we must all take action to protect these vital forests before it is too late. 试卷第22页（共28页） 试卷第23页（共28页） 学科网（北京）股份有限公司 $ 专题02 小猫钓鱼题 （Units 1-3，期中复习精准练） 目录导航 基础入门训练5篇 1 进阶拓展训练5篇 6 能力综合实践5篇 11 基础入门训练5篇 一、Complete the passage with the words or phrases in the box (选词或词组完成短文) A．satisfied   B．curious   C． driven   D．filled   E. interested   F.

Precipitation comes down, exactly, everywhere—in different forms. It may rain, hail, or snow. Whatever the form is, once it reaches the ground some water is 1 by trees and other plants. Some water enters the groundwater supply by infiltration. Most water runs off the surface, down a hill and finally into a river. Ditches and small streams may be dry when it does not rain. They can quickly 2 with water when it rains. Once the water finds its way into a stream or ditch, where does it go? If you have ever studied a map in detail, you will notice how rivers and streams form a network of waterways across the countryside. Little streams come together to form small rivers, which then join together and become medium-sized rivers. All these rivers may be branches of a large river, such as the Mississippi. Together, the network of rivers and streams forms a watershed, which drains the land of excess water. This type of pattern is 1 in many places in nature. In the human circulatory system, for example, in human lungs, when you breathe out, your lungs behave just like a 2 . The air in your lungs (which is like the water in a watershed) starts in the smallest vessels (which are like small streams), passing into larger vessels (that are like medium rivers) and finally into one large central air passage (which is like a large river). In the end, all the air in the lungs (which are like a large watershed) passes through this one large air passage, out your mouth, and to the 3 beyond, just as water in a watershed flows out the mouth of a large river and into the ocean!
