问答题The world is thirsty, so we should save water in our daily life.

Every day, too much water ______ in our school. We should save it.

In this section, there is one passage followed by a summary. Read the passage carefully, and then complete the summary below by choosing a maximum of three words from the passage to fill in each of the blanks. Remember to write the answers on the answer sheet.　　Questions 1 to 5 are based on the following passage.　　Everyone knows about pollution in the environment. Water, air, and land are all polluted. This means that pollution is everywhere. Now, scientists are looking inside our bodies to find out about internal pollution.　　In 2003, the Environmental Working Group studied nine people to measure the chemicals in their bodies. These nine people had an average of 53 cancer-causing chemicals in their bodies. They also had an average of 62 chemicals that can damage the brain, and 55 that can harm babies in pregnant women. Even though a lot of chemicals were found in human bodies, the chemicals were found in small amounts. The amounts were small enough that they were probably not hurting the people. However, scientists are worried because most of these chemicals were created by humans. Most of these chemicals did not exist 75 years ago. This proves that we have not only polluted the world—we have polluted our own bodies!　　How does this pollution get into our bodies? We come into contact with many chemicals every day. For example, everyone uses soap, skin lotion, and shampoo. However, few people know that these products contain harmful chemicals, some of which may cause memory loss. Chemicals known as DEA (diethanolamine) and TEA (triethanolamine) may seep into the skin and stop us from absorbing a helpful nutrient called “choline”. Choline is a nutrient that plays a crucial role in the memory cell making process in the developing brain. Some people worry that every time we wash our hair, we are decreasing our memories.　　Everyone knows they should brush their teeth regularly, but recent research has shown that some toothpastes can cause cancer. Fluoride is a key ingredient in many toothpastes. However, studies show that fluoride does not really protect our teeth. In fact, fluoride has been connected with bone cancer and other diseases. While we are trying to save our smiles, we could be damaging our health.　　Women are probably exposed to more chemicals than men because they use more beauty products. Recently, harmful chemicals have been found in nail polish, hair spray, deodorant, and perfume. The chemicals are called “phthalates”. Studies on animals have shown that phthalates can damage the liver, the kidneys, and the lungs. Cosmetic companies say the amounts of phthalates in their products are safe, but consumer protection groups disagree. They say some women use so many products that the levels are actually high. So, the more women try to look beautiful, the more they could be harming their health.　　In a futuristic story by Ray Bradbury, a man found a pristine stream on a new planet. When he drank from the stream, he died! Why? His body was so polluted that pure water was a poison to him! Perhaps that is only science fiction, but it reminds us to take care of our bodies. We must find ways to reduce the pollution we absorb.　　Summary:　　Like our polluted environment, our bodies are no longer pollution-free. Scientists now know that there is pollution in our bodies. On 　1　, we have 53 cancer-causing chemicals in our bodies. Even fluoride 　2　with bone cancer and other diseases. Some common cosmetics contain small amounts of chemicals, which seep into our 　3　when we use these products. They prevent us from absorbing the 　4　our bodies need. So, it is 　5　that we find ways to reduce the amount of chemicals in our bodies. We should remind our friends and families to take care of their bodies.

The world is thirsty, so we should save water in our daily life.

Granny often tells us ______ water in our daily life.

Practice 4　 Directions:　 Read the text below. Write an essay in about 120 words, in which you should summarize the key points of the text and make comments on them. Try to use your own words.　 In our modern world, when something wears out, we throw it away and buy a new one. The problem is that countries around the world have growing mountains of rubbish because people are throwing out more rubbish than ever before.　 How did we become a throwaway society? First of all, it is now easier to replace an object than to spend time and money to repair it. Thanks to modern manufacturing (制造业) and technology, companies are able to produce products quickly and inexpensively. Products are plentiful and cheap.　 Another cause is our love of disposable (一次性的) products. As busy people, we are always looking for ways to save time and make our lives easier. Companies produce thousands of different kinds of disposable products: paper plates, plastic cups, and cameras, to name a few.　 Our appetite for new products also returns to the problem. We are addicted to buying new things. Advertisements persuade us that newer is better and that we will be happier with the latest products. The result is that we throw away useful possessions to make room for new ones.　 All around the world, we can see the consequences of this throwaway lifestyle. Mountains of rubbish just keep getting bigger. To decrease the amount of rubbish and to protect the environment, more governments are requiring people to recycle materials. However, this is not enough to solve (解决) our problem.

The water in an auxiliary boiler should be tested daily for （）.

One of the questions coming into focus as we face growing scarcity of resources in the world is how to divide limited resources among countries. In the international development (1) com____, the coronal wisdom has been that the billion people living in poor countries could never expect to (2) r____ the standard of living that most of the people in North America enjoy, simply because the world does not contain enough iron ore, protein, petroleum, and so on. At the same time, we in the United States have continued to pursue super-affluence as though there were no limits (3)____ how much we could consume. We (4) m____ only 6 percent of the world’s people; yet we consume one third of the world’s resources.　　As long as the resources we consumed each year came primarily from (5) w____ our own boundaries, this was largely an internal matter. But as our resources come more and more from the outside world, we will no longer be able to think in (6)____ of “our” resources and “their” resources, but only of (7) c____ resources.　　As Americans consume such a(n) (8)____(proportion) share of the world’s resources, we have to question whether or not we can continue our pursuit of super-affluence in a world of (9)____(scarce). We are now reaching the point at which we must carefully examine the presumed link between our level of well-being and the level of material goods consumed. If you have only one crust of bread and get another crust of bread, your well-being is greatly enhanced. But if you have a loaf of bread, then an additional crust of bread doesn’t make (10) d____. In the eyes of most of the world today, Americans have their loaf of bread and are asking for still more. The prospect of a scarcity of, and competition in, the world’s resources requires that we re-examine the way in which we relate to the rest of the world.

Practice 5　　Water is essential for life. Yet many millions of people around the world face water shortages. Many millions of children die every year from water-borne diseases. And drought regularly afflicts some of the world’s poorest countries.　　The world needs to respond much better. We need to increase water efficiency, especially in agriculture. We need to free women and girls from the daily chore of hauling water. We must involve leaders of countries in decision-making on water management. We need to make sanitation a priority. This is where progress is lagging most. And we must show that water resources need not be a source of conflict. Instead, they can be a catalyst for cooperation.　　Significant gains have been made. But a major effort is still required. Our goal is to meet the internationally agreed targets for water and sanitation by 2015, and to build the foundation for further progress in the years beyond.　　This is an urgent matter of human development, and human dignity. Together, we can provide safe, clean water to the entire world’s people. The world’s water resources are our lifeline for survival, and [or sustainable development in the 21st century. Together, we must manage them better.
