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. The Kindle is more economical than new textbooks. B. Everything read on the Kindle is free of charge. C. The Kindle comes in different models as the iPod does. D. You cannot listen to music with a Kindle

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.

i. Process of paper recycling

ii. Less threat of waste paper to the environment

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  

The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. People of different cultures are more prone to contact certain illnesses because of the characteristic foods they consume.

That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates nitrites (commonly used to preserve color in meat) as well as other food additives caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which ingredients on the packaging label of processed food are helpful or harmful.

The additives that we eat are not all so direct. Farmers often give penicillin to cattle and poultry, and because of this, penicillin has been found in the milk of treated cows.

Sometimes similar drugs are administered to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.

A healthy diet is directly related to good health. Often we are unaware of detrimental substances we ingest. Sometimes well-meaning farmers or others who do not realize the consequences add these substances to food without our knowledge.

Question: What are nitrates used for?

A. They preserve the color of meat

B. They preserve flavor in package 

CThe are objects of research

D. They cause the animals become fatter
