Khi không gian bãi chôn lấp tăng lên, mối quan tâm đến việc làm phân trộn cũng tăng lên. Ủ phân là khi mọi người chất đống các chất hữu cơ, chẳng hạn như chất thải thực phẩm, và cho phép chúng phân hủy. Sản phẩm của sự phân hủy này là phân trộn. Có thể trộn thêm phân trộn vào đất để giúp đất giàu dinh dưỡng hơn và tốt hơn cho cây trồng phát triển. Mặc dù việc làm phân trộn dễ dàng thực hiện tại chỗ ở một nơi nào đó, chẳng hạn như nhà riêng hoặc trường học, nhưng khó có thể thực hiện sau khi rác được trộn hết. Điều này là do nhựa và các vật liệu vô cơ khác phải được loại bỏ khỏi đống ủ nếu không chúng sẽ gây ô nhiễm đất. Có rất nhiều nhựa trong rác, điều này khiến cho việc phân hủy trên diện rộng trở nên khó khăn

PAPER RECYCLING

A Paper is different from other waste produce because it comes from a sustainable resource: trees. Unlike the minerals and oil used to make plastics and metals, trees are replaceable. Paper is also biodegradable, so it does not pose as much threat to the environment when it is discarded. While 45 out of every 100 tonnes of wood fibre used to make paper in Australia comes from waste paper, the rest comes directly from virgin fibre from forests and plantations. By world standards, this is a good performance since the worldwide average is 33 percent waste paper. Governments have encouraged waste paper collection and sorting schemes and at the same time, the paper industry has responded by developing new recycling technologies that have paved the way for even greater utilization of used fibre. As a result, industry’s use of recycled fibres is expected to increase at twice the rate of virgin fibre over the coming years.

B Already, waste paper constitutes 70% of paper used for packaging and advances in the technology required to remove ink from the paper have allowed a higher recycled content in newsprint and writing paper. To achieve the benefits of recycling, the community must also contribute. We need to accept a change in the quality of paper products; for example, stationery may be less white and of a rougher texture. There also needs to support from the community for waste paper collection programs. Not only do we need to make the paper available to collectors but it also needs to be separated into different types and sorted from contaminants such as staples, paperclips, string and other miscellaneous items.

C There are technical limitations to the amount of paper which can be recycled and some paper products cannot be collected for re-use. These include paper in the form of books and permanent records, photographic paper and paper which is badly contaminated. The four most common sources of paper for recycling are factories and retail stores which gather large amounts of packaging material in which goods are delivered, also offices which have unwanted business documents and computer output, paper converters and printers and lastly households which discard newspapers and packaging material. The paper manufacturer pays a price for the paper and may also incur the collection cost.

D Once collected, the paper has to be sorted by hand by people trained to recognise various types of paper. This is necessary because some types of paper can only be made from particular kinds of recycled fibre. The sorted paper then has to be repulped or mixed with water and broken down into its individual fibres. This mixture is called stock and may contain a wide variety of contaminating materials, particularly if it is made from mixed waste paper which has had little sorting. Various machineries are used to remove other materials from the stock. After passing through the repulping process, the fibres from printed waste paper are grey in colour because the printing ink has soaked into the individual fibres. This recycled material can only be used in products where the grey colour does not matter, such as cardboard boxes but if the grey colour is not acceptable, the fibres must be de-inked. This involves adding chemicals such as caustic soda or other alkalis, soaps and detergents, water-hardening agents such as calcium chloride, frothing agents and bleaching agents. Before the recycled fibres can be made into paper they must be refined or treated in such a way that they bond together.

E Most paper products must contain some virgin fibre as well as recycled fibres and unlike glass, paper cannot be recycled indefinitely. Most paper is down-cycled which means that a product made from recycled paper is of an inferior quality to the original paper. Recycling paper is beneficial in that it saves some of the energy, labour and capital that go into producing virgin pulp. However, recycling requires the use of fossil fuel, a non-renewable energy source, to collect the waste paper from the community and to process it to produce new paper. And the recycling process still creates emissions which require treatment before they can be disposed of safely. Nevertheless, paper recycling is an important economical and environmental practice but one which must be carried out in a rational and viable manner for it to be useful to both industry and the community.

Giup e với . Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions. Cell phones are an integrated part of our society at this point, and their main use is communication. They keep students in touch with the rest of the world by giving them the power to interact with it . In my day, if you forgot your lunch you were at the mercy of the office calling home for you. Now, students have the ability to solve their own problems and handle certain "emergencies" on their own. Cell phones also allow students the ability when the time is right, to keep in touch with students at other schools or friends that don't go to school. While not an educational benefit directly, better relationships can lead to higher self-esteem and reduce isolation, which is good for everybody. In the same way, camera phones allow students to capture the kinds of memories that help build a solid school culture, and, in some cases, can act as documentation of misbehavior in the same way that store cameras provide evidence and deter bad behavior. Academically, the cell phone can act as to record video of a procedure of explanation that may need to be reviewed later. It could be used to record audio of a lecture, as well, for later review. And just imagine if class could be easily " taped " for students who are absent? What if they could even be streamed and seen from home instantly? The iPod is a little trickier, because its function varies greatly by model. At its heart , it is a media player, and I know for a fact that many students work better while listening to music. For this reason, they can have a good effect by keeping students from getting too distracted while working ( ironic , because we mostly think of them AS distractions!). If it is a WIFI compatible model, and wireless internet is available, the iPod can be a great tool for looking up information or digging into things more deeply. Depending on the model, it may be able to act as a camera and video recorder as well (with the same benefits as the cell phone). Devices like the Kindle could, conceivably, make learning a lot easier. Imagine carrying all your textbooks in the palm of your hand, rather than strapped to your back! Though expensive, compared to buying new textbooks, the Kindle is a bargain. Many of the books used in high school English classes are actually FREE on the Kindle. 11. The passage mainly discusses ____. A. how some electronic devices are used in education B. how to use electronic devices in the classroom C. what is the best electronic device used in education D. which electronic device will be used as the textbooks 12. The word " it ' in the passage refers to ____. A. the power B. the world C. the rest of the world D. the main use 13. The phrase " at the mercy of " mostly means ____. A. completely dependent on B. at request of C. thankful to D. under orders 14. According to the passage, cell phones do NOT ____. A. help students keep in touch with their friends B. allow students to capture of memories C. help students record audio of a lecture D. enable students to write their assignment 15. The word " which " in the passage refers to ____. A. building better relationships B. achieving higher self-esteem C. that relationships lead to higher self-esteem D. having higher-esteem and lower isolation 16. Which of the following is closest in meaning to the word " taped "? A. recorded B. reviewed C. streamed D. seen 17. The phrase " At its heart " mostly refers to ____. A. the main function B. the core part C. the central unit D. the best usage 18. The word " ironic " is closest in meaning to ____. A. lucky B. special C. funny D. particular 19. Which of the following is NOT true about the iPod according to the passage? A. The iPod can be used to make phone calls. B. The iPod can be connected to the Internet. C. The iPod can be used to record videos D. The iPod comes in different models. 20. Which of the following is true about the kindle according to the passage? A.

a. Environmental problems: What are they?

b. Environmental protection: How important is it?

c. Environmental solutions: How practical are they?

The environment we live in is facing many serious problems. We need to be aware of these problems so that we can find ways to protect nature.

A. Global warming is the rise in the average temperature of the earth's atmosphere. It is one of the biggest issues facing humans today. It can have serious consequences such as rising sea levels, polar ice melting, and extreme weather events like floods or heatwaves.

B. Another environmental problem is the cutting and clearing of natural forests. The loss of forests can have a negative impact on the environment. It can damage the natural habitats of many animals and put wildlife in danger. It can also destroy the natural soil and lead to climate change.

C. Air pollution is also a serious problem. It is mainly caused by waste gases that come out of vehicles, machines, or factories. When these harmful gases combine with the water in the air, they come down as rain or snow, which can damage all forms of life. In addition, this problem leads to global warming and climate change. It is also a major cause of respiratory diseases or even lung cancer.

D. Around the world, the number of endangered animals is rising. Many of them disappear because of pollution and climate change. In addition, humans illegally hunt and kill animals, and catch too many fish at once. This is upsetting the natural balance of ecosystems, which can be harmful to all living and non-living things.

Tạm dịch:

a. Các vấn đề về môi trường: Chúng là gì?

b. Bảo vệ môi trường: Nó quan trọng như thế nào?

c. Các giải pháp môi trường: Chúng thực tế như thế nào?

Môi trường chúng ta sống đang phải đối mặt với nhiều vấn đề nghiêm trọng. Chúng ta cần nhận thức rõ những vấn đề này để có thể tìm cách bảo vệ thiên nhiên.

A. Sự nóng lên toàn cầu là sự gia tăng nhiệt độ trung bình của khí quyển trái đất. Đó là một trong những vấn đề lớn nhất mà con người phải đối mặt ngày nay. Nó có thể gây ra những hậu quả nghiêm trọng như mực nước biển dâng cao, băng tan ở hai cực và các hiện tượng thời tiết khắc nghiệt như lũ lụt hoặc sóng nhiệt.

B. Một vấn đề môi trường khác là chặt phá rừng tự nhiên. Việc mất rừng có thể có tác động tiêu cực đến môi trường. Nó có thể làm hư hại môi trường sống tự nhiên của nhiều loài động vật và khiến động vật hoang dã gặp nguy hiểm. Nó cũng có thể phá hủy đất tự nhiên và dẫn đến biến đổi khí hậu.

C. Ô nhiễm không khí cũng là một vấn đề nghiêm trọng. Nguyên nhân chủ yếu là do khí thải từ xe cộ, máy móc hoặc nhà máy. Khi những khí độc hại này kết hợp với nước trong không khí, chúng sẽ tạo thành mưa hoặc tuyết, có thể gây hại cho mọi dạng sống. Ngoài ra, vấn đề này còn dẫn đến hiện tượng nóng lên toàn cầu và biến đổi khí hậu. Nó cũng là nguyên nhân chính gây ra các bệnh về đường hô hấp hay thậm chí là ung thư phổi.

D. Trên khắp thế giới, số lượng các loài động vật có nguy cơ tuyệt chủng đang tăng lên. Nhiều con trong số chúng biến mất vì ô nhiễm và biến đổi khí hậu. Ngoài ra, còn vì con người săn bắt và giết động vật một cách bất hợp pháp và đánh bắt quá nhiều cá cùng một lúc. Điều này đang làm đảo lộn sự cân bằng tự nhiên của các hệ sinh thái, có thể gây hại cho tất cả các sinh vật sống và không sống.

Read the passage below carefully, and then choose the best answer

Conservation conflicts arise when natural-resource shortages develop in the face of steadily increasing demands from a growing human population. Controversy frequently surrounds how a resource should be used, or allocated, and for whom. For example, a river may supply water for agricultural irrigation, habitat for fish, and water-generated electricity for a factory. Farmers, fishers, and industry leaders vie for unrestricted access to this river, but such freedom could destroy the resource, and conservation methods are necessary to protect the river for future use.

Conflicts worsen when a natural resource crosses political boundaries. For example, the headwaters, or source, of a major river may be located in a different country than the country through which the river flows. There is no guarantee that the river source will be protected to accommodate resource needs downstream. In addition, the way in which one natural resource is managed has a direct effect upon other natural resources. Cutting down a forest near a river, for instance, increases erosion, the wearing away of topsoil, and can lead to flooding. Eroded soil and silt cloud the river and adversely affect many organisms such as fish and important aquatic plants that require clean, clear freshwater for survival.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions

Researchers in the field of psychology have found that one of the best way to make an important decision, such as choosing a university to attend or business to invest in, involves the utilization of a decision worksheet. Psychologists who study optimization compare the actual decisions made by people to theretical ideal decisions to see how similar they are. Proponents of the worksheet procedure believe that it will yield optimal, that is, the best decisions. Although there are several variations on the exact format that worksheets cam take, they are all similar in their essential aspects.

Worksheets require defining the problem in a clear and concise way and then listing all possible solutions to the problem. Next, the pertinent considerations that all possible solutions to the problem. Next, the pertinent considerations that will be affected by each decision are listed, and the relative importance of each consideration or consequence is determined. Each consideration is assigned a numerical value to reflect its relative importance. A decision is mathematically calculated by adding these values together. The alternative with the highest number of points emerges as the best decision.

Since most important problems are multifaceted, there are several alternatives to choose from, each with unique advantages and disadvantages. One of the benefits of a pencil and paper decision-making procedure is that it permits people to deal with more variables than their minds can generally comprehend and remember. On the average, people can keep about seven ideas in their minds at once. A worksheet can be especially useful when the decision involves a large number of variables with complex relationships. A realistic example for many college students is the question "What will I do after graduation?" A graduate might seek a position that offers specialized training, pursue an advanced degree, or travel abroad for a year.

A decision-making worksheet begins with a succinct statement of the problem that will also help to narrow it. It is important to be clear about the distinction between long-range and immediate goals because long-range goals often involve a different decision than short-range ones. Focusing on long-range goals, a graduating student might revise the question above to "What will I do after graduation that will lead to a successful career?"

Question: Which of the following terms is defined in the passage?

A. Proponents (para. 1)

B. Optimal (para. 1

C. Variables (para. 3)

D. Long-range goals (para. 4)
