          Human Nutrition is the study of how food affects the health and survival of the human body. Human beings require food to grow, reproduce, and maintain good health. Without food, our bodies could not stay warm, build or repair tissue, or maintain the heartbeat. Eating the right foods can help us avoid certain diseases or recover faster when illness occurs. These and other important functions are fueled by chemical substances in our food called nutrients. Nutrients are classified as carbohydrates, proteins, fats, vitamins, minerals, and water.

          When we eat a meal, nutrients are released from food through digestion. Digestion begins in the mouth by the action of chewing and the chemical activity of saliva, a watery fluid that contains enzymes, certain proteins that help break down food. Further digestion occurs as food travels through the stomach and the small intestine, where digestive enzymes and acids liquefy food and muscle contractions push it along the digestive tract. Nutrients are absorbed from the inside of the small intestine into the bloodstream and carried to the sites in the body where they are needed. At these sites, several chemical reactions occur, which ensures the growth and function of body tissues. The parts of foods that are not absorbed continue to move down the intestinal tract and are eliminated from the body as feces.

          Once digested, carbohydrates, proteins, and fats provide the body with the energy it needs to maintain its many functions. Scientists measure this energy in kilocalories, the amount of energy needed to raise one kilogram of water one degree Celsius. In nutrition discussions, scientists use the term calorie instead of kilocalorie as the standard unit of measure in nutrition.

          Nutrients are classified as essential or nonessential. Nonessential nutrients are manufactured in the body and do not need to be obtained from food. Examples include cholesterol, a fatlike substance present in all animal cells. Essential nutrients must be obtained from food sources, because the body either does not produce them or produces them in amounts too small to maintain growth and health. Essential nutrients include water, carbohydrates, proteins, fats, vitamins, and minerals.

          An individual needs varying amounts of each essential nutrient, depending upon such factors as gender and age. Specific health conditions, such as pregnancy, breast-feeding, illness, or drug use, make unusual demands on the body and increase its need for nutrients. Dietary guidelines, which take many of these factors into account, provide general guidance in meeting daily nutritional needs.

Humans have struggled against weeds since the beginnings of agriculture. Marring our gardens is one of the milder effects of weeds – any plants that thrive where they are unwanted. They clog waterways, destroy wildlife habitats, and impede farming. Their spread eliminates grazing areas and accounts for one-third of all crop loss. They compete for sunlight, nutrients, and water with useful plants.

The global need for weed control had been answered mainly by the chemical industry. Its herbicides are effective and sometimes necessary, but some pose serious problems, particularly if misused. Toxic compounds threaten animal and public health when they accumulate in food plants, groundwater, and drinking water. They also harm workers who apply them.

In recent years, the chemical industry has introduced several herbicides that are more ecologically sound. Yet new chemicals alone cannot solve the world‟s weed problems. Hence, scientists are exploring the innate weed-killing powers of living organisms, primarily insects and microorganisms.

The biological agents now in use are environmentally benign and are harmless to humans. They can be chosen for their ability to attack selected targets and leave crops and other plants untouched. In contrast, some of the most effective chemicals kill virtually all the plants they come in contact with, sparing only those that are naturally resistant or have been genetically modified for resistance. Furthermore, a number of biological agents can be administered only once, after which no added applications are needed. Chemicals typically must be used several times per growing season.

Understanding India's Caste System

It has been said that life is what we make of it. In other words, if we work hard and focus on our goals, we can have great careers and enjoy high status is society. However, these opportunities don‟t exist for everyone. In some places, the family you are born into will decide almost everything about your life. India‟s caste system is an example of this.

The caste system is a major part of the Hindu religion that has existed for thousands of years. It is a way of organizing and grouping people based on the occupation of the family. Castes will determine whom people can socialize with and their place in society. Originally, a person‟s caste was supposed to be determined by their personality, but over time it has been linked to their job and family.

There are four classes, also known as varnas, in India‟s caste system. The highest one is Brahmin. People in this class have jobs in education and religion. These are seen as extremely important functions for the society as they deal with the knowledge. The second highest level is the Kshatriya, or ruling class. People from this group can be soldiers, landowners, or have jobs in politics. The class beneath this is the Vaishya. These people often work in the commercial sector as merchants. The fourth class level is the Shudra. Shudras typically work as unskilled labourers doing factory or farm work, or they may also be employed as artists.

There is another group, the Harijan, that is at the bottom and considered to be outside of the caste system. For many years, they were known as Untouchables, people from this caste held the most undesirable jobs in society, such as cleaning up garbage. Furthermore, they weren‟t allowed to pray at public temples or drink water from the same wells as other classes. If someone from another caste came into contact with an Untouchable, they were considered dirty and would be expected to bathe vigorously to clean themselves.

Although the caste system still exists in India, the government is taking steps to improve the living conditions and decrease unemployment rates for the Shudras and Harijan. This includes providing better health care, offering literacy programmes, and making sure that people from higher social classes do not exploit them. It seems unlikely that the caste system will disappear any time soon, but the overall conditions for those at the bottom do seem to be improving.

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 from 37 to 44.

Life Writings

The diary and the letter were the most extensively practiced forms of life writings in eighteenth-century America. From the numerous examples of these two types of writing from the period, a portrait of daily life of the period can be gleaned.

Many of the diaries that were kept during this period were life diaries by authors interested in maintaining day-to-day records of reflective self-examination, but some of the most compelling were situational diaries; those prompted by and limited to lengthy descriptions of personal reflections about a particular event. Three of the many situational journals of this period are those written by Sarah Kemble Knight, William Burd II, and Dr. Alexander Hamilton. Sarah Kemble Knight's diary of her five-month trip at the end of 1704 and the beginning of 1705 from Boston to New Haven to New York and back again to Boston was published more than a century later as The Journal of Madam Knight. Though this diary does include an account of the hardship that she encountered along the way, it is principally composed of humorous descriptions of and commentary on the hospitality that she was offered and the manners of those that she encountered. William Burd II kept two diaries to describe his experiences on a 1729 surveying expedition to settle a border dispute between Virginia and North Carolina. One of the diaries, History of the Dividing Line between Virginia and North Carolina, was published in 1842, while its companion, Secret Diary, was published in 1929. In these diaries, Burd used a humorous and satirical approach to describe not just the day-to-day events of the trip but also the characteristics which set his beloved Virginia culture apart from the (in his opinion) decidedly less praiseworthy culture of those non-Virginians that he encountered in his trip. Dr. Alexander Hamilton's Itinerarium (1744) describes a four-month voyage of discovery undertaken by Hamilton through the mid-Atlantic and New England colonies; in the diary that he kept of this trip. Hamilton provides considerable commentary on the social customs of various areas, comparing the customs and culture of the better homes of the American colonies with those of the great salons of Europe.

Letter-writing also held a place of importance in eighteenth-century America (indeed, the ability to produce cultured letters was considered a form of art), and many letters extant from that period provide insights into the culture, mores, and styles of written communication of that era. Many of the letter writers employed devices in common usage in European models of the time, demonstrating that letter writers felt a sense of cohesiveness with the cultured classes of Europe: John and Abigail Adams signed the names Lysander and Constantia to their early letters, while Thomas Jefferson created an elaborate dialogue between his head and his heart to discuss the nature of friendship in a 1786 letter to Maria Cosway. The variety of purposes that these letters served provides additional insight into the priorities of the society of the time. The letters were used to cement love matches and friendships, as the previously mentioned letters did; they were the primary method for relaying news among family and friends who were scattered across various geographic locations; they were often used as a means of carrying out business in this era before more rapid long-distance communication; they were often used used as a way of sharing professional, social, or political ideas among leaders in various fields who perhaps had no other way to get together and exchange ideas.

Ở Châu Phi, một công ty thực phẩm nổi tiếng đã cố gắng bán thức ăn trẻ em của mình bằng cách quảng cáo nó với hình ảnh của một em bé trên nhãn. Họ không biết rằng quốc gia đặc biệt này chỉ sử dụng nhãn để hiển thị hình ảnh của thực phẩm bên trong. Khi Pepsico sử dụng khẩu hiệu "Hãy sống với Pepsi" ở Đài Loan, họ không biết rằng nó sẽ được dịch sang tiếng Trung Quốc vì “Pepsi đưa tổ tiên của bạn trở về từ thế cõi chết”.

Những hiểu lầm như những điều này về ngôn ngữ hoặc về văn hóa đôi khi thật khôi hài nhưng cũng có thể gây ra tổn thương hoặc sự tức giận thực sự. Phong cách kinh doanh rất khác nhau ở các quốc gia khác nhau và những gì bình thường trong một nền văn hóa có thể hoàn toàn không được chấp nhận ở một nền văn hóa khác.

Xã hội ở các quốc gia khác nhau có thể là khó khăn. Ví dụ, ở các nước Ả Rập, mọi người không thảo luận về kinh doanh trong các bữa ăn. Tặng quà là một vấn đề tiềm năng khác: ở Anh, hầu hết mọi người đều tặng quà cho một bữa tiệc tối, nhưng ở nhiều quốc gia, điều này không lịch sự vì điều đó cho thấy bạn nghĩ rằng chủ nhà nghèo.
