(Title)

Production bottlenecks are generally considered to be temporary blockades to increased output; they can be thrown up anywhere along the course of a production process. Some are easy to identify and to remedy, while others are devilish.

The bottleneck that is easy to cope................................. is stationary. Work-in-process inventory piles..................... quickly behind it; clearly, little is getting through. Its cause is usually also clear – a machine has broken........................ or key workers are absent or demand has simply outstripped the clear, rated capacity of a machine – and the remedy follows easily. Such bottlenecks often occur........................ service operations, causing customer waits.

More subtle are bottlenecks that shift from one part of the process to another or that have no clear cause. Inventories build up in different places and at different times. Such bottlenecks creep up on management and demand more thorough investigation. Perhaps they were detected as flaws in a product’s quality caused inadvertently by one or more workers trying to keep pace with production demands that should not have been placed on them. Or, they may be caused by missing parts. They may be caused by new product startup or changes in the mix of products through the factory. In such cases the remedies are less clear-cut, and some analysis is called for.
Analyze the sentences according to structure and grammar use.
1. ‘…a machine has broken…’ is written in the present perfect tense. 2. The negative form of: ‘a machine has broken...’, is: ‘…a machine doesn’t have broken …’ 3. The words in bold in ”… clearly, little is getting through.” and “…more workers trying to keep pace with production…” are in the present progressive tense. 4. The negative form of “…and the remedy follows easily.” is “and the remedy doesn’t follow easily.”

    Daniel Ferreira, 24, is a guy who had to learn to overcome expectations from the day hewas born, without his arms, due to a treatment with thalidomy that his mother had to do during pregnancy. “Some relatives did not bet a chip on me; they saw me as a poor thing,” he says. It turns out that he did not put any brakes on any ambition, he did very well in life and,painting with his feet and mouth, he became a fine artist.
  About the International Day of People with Disabilities, celebrated last Wednesday (3), he says: “Unfortunately, we still need special days toremember minorities, such as blacks,homosexuals and the disabled. Brazil is not prepared in any way to meet the needs of people with disabilities. There is no accessibility. Neither public nor private schools have a structure. We still have a lot to fight for ”.
     The boy speaks properly on the subject, since he had to fight hard to be able to study in a regular public school, from the age of seven. The principal argued that the state institution was not supported to receive a student with a disability. His father, Francisco, was the one who had to build a special desk, without State aid, so that Daniel could write with his feet.

Pollution


Pollution is the introduction of harmful materials into the environment. These harmful materials are called pollutants. Pollutants can be natural, such as volcanic ash. They can also be created by human activity, such as trash or runoff produced by factories. Pollutants damage the quality of air, water, and land.

Many things that are useful to people produce pollution. Cars spew pollutants from their exhaust pipes. Burning coal to create electricity pollutes the air. Industries and homes generate garbage and sewage that can pollute the land and water. Pesticides – chemical poisons used to kill weeds and insects – seep into waterways and harm wildlife. 

All living things – from one-celled microbes to blue whales – depend on Earth's supply of air and water. When these resources are polluted, all forms of life are threatened.

Pollution is a global problem. Although urban areas are usually more polluted than the countryside, pollution can spread to remote places where no people live. For example, pesticides and other chemicals have been found in the Antarctic ice sheet. In the middle of the northern Pacific Ocean, a huge collection of microscopic plastic particles forms what is known as the Great Pacific Garbage Patch.

Air and water currents carry pollution. Ocean currents and migrating fish carry marine pollutants far and wide. Winds can pick up radioactive material accidentally released from a nuclear reactor and scatter it around the world. Smoke from a factory in one country drifts into another country.

Language changes all the time. Even though grammar changes more slowly than vocabulary, it is not a set of unalterable rules. There are sometimes disagreements about what is correct English and what is incorrect. 'Incorrect' grammar is often used in informal speech. Does that make it acceptable? John Eastwood, author of Oxford Guide do English Grammar says: "Where there is a difference between common usage and opinions about correctness, I have pointed this out." This information is important for learners. In some situations, it may be safer for them to use the form which is traditionally seen as correct. The use of a correct form in an unsuitable context, however, can interfere with understanding just as much as a mistake. To help learners to use language which is appropriate for a given occasion, students must know that there are usages as formal, informal, literary and so on. Only one alternative has no grammatical error. Which is it?

CRIMINALS HAVE SMALLER BRAIN SIZE, SAYS STUDY


        A new study has found that antisocial people are more likely to have smaller areas of their brain. Researchers said criminals' brains had a different structure to the brains of people who followed the law. The study is published in the journal "Lancet Psychiatry". Researchers used data from 672 people born in 1972-73. They looked at records of the people's antisocial behaviour between the ages of seven and 26. At the age of 45, the researchers scanned the people's brains. Eighty of the people had a history of criminal and antisocial behaviour from being early teenagers. Researchers found that the areas of the brain linked to emotions, motivation and behaviour control were smaller in the long-term criminals' brains. 

        Professor Terrie Moffitt, a co-author of the research, said the research could help doctors understand what is behind long-term antisocial behaviour. She said the antisocial people in the study may have behaved badly because of their brain structure. She said: "They are actually operating under some [disability] at the level of the brain." She added that because of this, we needed to care for these people in a kinder way. Lead author Dr Christina Carlisi said: "Differences in brain structure might make it difficult for people to develop social skills. This may prevent them from engaging in antisocial behaviour. These people could benefit from more support throughout their lives."

Why are animals important to human beings?

There are a number of reasons why animals are important to human beings. The main reason is that animals benefit us personally, socially and economically.

Since the time of our cavemen ancestors, there have been interactions between humans and animals. Animals can be our friends, companions, protectors, benefactors and comforters. Research studies indicate that people who own pets and have close bond with them have higher self-esteem. They are also generally happier and healthier. There are many reported cases in which pets protected their owners and family members. In the United States, a pet dog alerted its owners that their babysitter was abusive. A couple who hired a babysitter to take care of their baby noticed that their pet dog was aggressive to the babysitter. Upon investigation, they discovered that their child was abused by the babysitter.

Animals provide many other benefits to humans. Insulin, a hormone in our body which controls the amount of sugar absorbed by our blood, could not be artificially produced previously. It had to be derived from cows and pigs. Nowadays, even though animal insulin has largely been replaced by artificial human insulin, the former is still available on prescription. Trained guide dogs are available to serve as loyal companions and ‘pairs of eyes’ for the blind. In the past, hunters took along hunting dogs to track, sniff out and catch wild game. When night fell, the canines were the hunters’ companions and protectors. In rehabilitation centers, animals are used to help the sick recover. For instance, petting a pony helps to lift a sick child’s spirit.

Throughout history, animals have helped humans. We use animals to work for us. In the agricultural sector, oxen pull ploughs before seeds are planted in the soil. We use horses for transportation purposes. They pull carriages and covered wagons for us. Even though oxen and horses are rarely used for farming and travelling purposes respectively today, the horses are still being used for riding and racing. They are also used to participate in contests in order to win awards. Farmers depend on animals such as cattle, poultry, sheep, goats, among others, for their horses are rarely used for farming and travelling purposes respectively today, the horses are still being used for riding and racing. They sell the animals’ meat, milk and eggs to earn money. In the fishing industry, although the use of modern equipment and technology have replaced the use of animals to catch fish, fishermen in some parts of the world still use animals like dolphins, otters and cormorants for the purpose.

Another indirectly way in which animals help us is that they assist in the reproduction of a variety of fruit and vegetable crops, which are an important part of our healthy diet. Without animals to help disperse seeds and pollinate plants, many of them would have become extinct.

In conclusion, animals are important to human beings because they benefit us socially, personally as well as economically. Since they are of great benefit to us, we should treat them well.

READ THE FOLLOWING TEXT CAREFULLY, AND THEN CHOOSE THE ALTERNATIVE THAT BEST COMPLETES THE STATEMENTS BELOW, ACCORDING TO THE TEXT. 

Mrs Parker died suddenly in October. She and Mr Parker lived in a Victorian house next to ours, and Mr Parker was my piano teacher. He commuted to Wall Street, where he was a securities analyst, but he had studied at Juilliard and gave lessons on the side – for the pleasure of it, not for money. His only students were me and the church organist.
The word “tragic” was mentioned in connection with her death. She and Mr Parker were in the middle of their middle age, and neither of them had ever been seriously ill. It was heart failure, and unexpected. My parents went to see Mr Parker as soon as they got the news, since they took their responsibilities as neighbours seriously, and two days later they took me to pay a formal condolence call. 
I loved the Parkers’ house. It was a Victorian house, and was shaped like a wedding cake. The living-room was round, and all the walls curved. The third floor was a tower. Every five years the house was painted chocolate brown, which faded gradually to the colour of weak tea. The front-wall window was a stained-glass picture of a fat baby holding a bunch of roses.
On Wednesday afternoons, Mr Parker came home on an early train, and I had my lesson. Mr Parker’s teaching method never varied. He never scolded or corrected. The first fifteen minutes were devoted to a warm-up in which I could play anything I liked. Then Mr Parker played the lesson of the week. His playing was terrifically precise, but his eyes became dreamy and unfocused. Then I played the same lesson, and after that we worked on the difficult passages, but basically he wanted me to hear my mistakes. After that, we sat in the solarium and discussed the next week’s lesson. Mr Parker usually played a record and talked in detail about the composer, his life and times. Mrs Parker used to leave us a tray of cookies and lemonade, cold in the summer and hot in the winter. When the cookies were gone, the lesson was over and I left, passing the Victorian child in the hallway.
