Anthropologists have pieced together the little they know about the history of left - handedness and right - handedness from indirect evidence. Though early men and women did not leave written records, they did leave tools, bones, and pictures. Stone Age hand axes and hatchets were made from stones that were carefully chipped away to form sharp cutting edges. In some, the pattern of chipping shows that these tools and weapons were made by right handed people, designed to fit comfortably into a right hand. Other Stone Age implements were made by or for left-handers Prehistoric pictures, painted on the walls of caves, provide further clues to the handedness of ancient people. A right - hander finds it easier to draw faces of people and animals facing toward the left, whereas a left - hander finds it easier to draw faces facing toward the right. Both kinds of faces have been found in ancient painting. On the whole, the evidence seems to indicate that prehistoric people were either ambidextrous or about equally likely to be left - or right - handed.
But, in the Bronze Age, the picture changed. The tools and weapons found from that period are mostly made for right - handed use. The predominance of right - handedness among humans today had apparently already been established.

The author implies that which of the following developments occurred around the time of the Bronze Age

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.

      Contrary to popular belief, one does not have to be a trained programmer to work online. Of course, there are plenty of jobs available for people with high-tech computer skills, but the growth of new media has opened up a wide range of Internet career opportunities requiring only a minimal level of technical expertise. Probably one of the most well-known online job opportunities is the job of Webmaster. However, it is hard to define one basic job description for this position. The qualifications and responsibilities depend on what tasks a particular organization needs a Webmaster to perform.

      To specify the job description of a Webmaster, one needs to identify the hardware and software the website the Webmaster will manage is running on. Different types of hardware and software require different skill sets to manage them. Another key factor is whether the website will be running internally or externally (renting shared space on the company servers). Finally, the responsibilities of a webmaster also depend on whether he or she will be working independently, or whether the firm will provide people to help. All of these factors need to be considered before one can create an accurate webmaster job description.

      Webmaster is one type of Internet career requiring in-depth knowledge of the latest computer applications. However, there are also online jobs available for which traditional skills remain in high demand. Content jobs require excellent writing skills and a good sense of the web as a “new media”.

      The term “new media” is difficult to define because it compasses a constantly growing set of new technologies and skills. Specifically, it includes websites, email, internet technology, CD-ROM, DVD, streaming audio and video, interactive multimedia presentations, e-books, digital music, computer illustration, video games, virtual reality, and computer artistry.

      Additionally, many of today’s Internet careers are becoming paid-by-the-job professions. With many companies having to downsize in tough economic items, the outsourcing and contracting of freelance workers online has become common business practice. The Internet provides an infinite pool of buyers from around the world with whom freelancers can contract their services. An added benefit to such online jobs is that freelancers are able to work on projects with companies outside their own country.

      How much can a person make in these kinds of careers? As with many questions related to today’s evolving technology, there is no simple answer. There are many companies willing to pay people with Internet skills salaries well over $70,000 a year. Generally, webmasters start at about $30,000 per year, but salaries can vary greatly. Freelance writers working online have been known to make between $40,000 to $70,000 a year.

Clara Barton became known as “ The Angel of the Battlefield” during the American Civil War. Born in Oxford, Massachusetts in 1821, Clara Barton’s interest in helping soldiers on the battlefield began when she was told army stories from her father. Another event that influenced her decision to help soldiers was an accident her brother had. His injuries were cared for by Barton for 2 year. At the time, she was only 11 years old. Barton began teaching school at the age of 15. She taught for 18 years before she moved to Washington, D.C in 1854.
The civil war broke out 6 years later. Immediately, Barton started war service by helping the soldiers with their needs. At the battle of Bull run, Clara Barton received permission from the government to take care of the sick and hurt. Barton did this with great empathy and kindness. She acknowledged each soldier as a person . her endurance and courage on the battlefield were admired by many. When the war ended in 1865 , she used 4 years of her life to assist the government in searching for soldiers who were missing during the war.
The search for missing soldiers and years of hard work made her feeble physically. In 1869, her doctors recommended a trip to Europe for a rest. While she was on vacation , she became involved with the International Red Cross, an organization set up by the Geneva Convention in 1864. Clara Barton realized that the Red Cross would be a best help to the United States. After she returned to the United States, she worked very hard to create an American Red Cross. She talked to government leaders and let American people know about the Red Cross. In 1881, the National Society of the Red Cross was finally established with its headquarters in Washington ,D.C. Clara Barton managed its activities for 23 years.
Barton never let her age stop her from helping people. At the age of 79, she helped food victims in Galveston, Texas. Barton finally resigned from the Red Cross in 1904. She was 92 years old and had truly earned her title “ The Angel of the Battle”.

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

The increase in urbanization causes different problems. Air and water pollution are amongst the major issue we have to tackle.

In the first place, cars, factories and burning waste emit dangerous gases that change the air quality in our cities and pose threats to our health. Dangerous gases such as carbon dioxide and nitrogen oxides cause respiratory diseases, for instant, bronchitis and asthma. Those are also proved to have long-term effects on the environment.

Furthermore, with the increased population, it becomes difficult to manage the waste generated in cities. Most of the waste is discharged or dumped into rivers or onto streets. The waste pollutes water and makes it unfit for human consumption. Subsequently, it becomes more and more difficult for city dwellers to get clean water. Some cities in Africa are unable to provide adequate water supply because most of the water is lost in pipe leakages. In fact, most city dwellers in developing countries are forced to boil their water or to buy bottled water, which is very expensive.

There are several actions that could be taken to eradicate the problems described above. Firstly, a simple solution would be joining community efforts to address problems affecting your city. Ask your parents, friends and relatives to join in as well. These efforts might include clean-up campaigns, recycling projects and a signature campaign to ask the government to do something about the situation. A second measure would be encouraging your teacher to talk about these problems and to discuss how young people can help to solve them. Finally, writing to local organizations working on these issues for ideas on how you can contribute to solve them.

Read the passage carefully and choose the correct answer.

In the past, both men and women were expected to be married at quite young ages. Marriages were generally arranged by parents and family, with their children having little chance to say no in the matter. In the past it was not surprising to find that a bride and groom had only just met on the day of their engagement or marriage.

In modern Vietnam, this has changed completely as people choose their own marriage-partners based on love, and in consideration primarily to their own needs and wants. Moreover early marriage is quite illegal.

The traditional Vietnamese wedding is one of the most important of traditional Vietnamese occasions. Regardless of westernization, many of the age-old customs practiced in a traditional Vietnamese wedding continue to be celebrated by both Vietnamese in Vietnam and overseas, often combining both western and eastern elements. Besides the wedding ceremony, there is also an engagement ceremony which takes place usually half a year or so before the wedding. Due to the spiritual nature of the occasion, the date and time of the marriage ceremony are decided in advance by a fortune teller. The traditional Vietnamese wedding consists of an extensive array of ceremonies: the first is the ceremony to ask permission to receive the bride, the second is the procession to receive the bride (along with the ancestor ceremony at her house), the third is to bring the bride to the groom's house for another ancestor ceremony and to welcome her into the family, then the last is a wedding banquet. The number of guests in attendance at these banquets is huge, usually in the hundreds. Several special dishes are served. Guests are expected to bring gifts, often money, which the groom and bride at one point in the banquet will go from table to table collecting.

Centuries ago, man discovered that removing moisture from food helped to preserve it, and that the easiest way to do this was to expose the food to sun and wind. In this way the North American Indians produced pemmican (dried meat ground into powder and made into cakes), the Scandinavians made stock fish and the Arabs dried dates and apricots.
All foods contain water - cabbage and other leaf vegetables contain as much as 93% water, potatoes and other root vegetables 80%, lean meat 75% and fish anything from 80% to 60% depending on how fatty it is. If this water is removed, the activity of the bacteria which cause food to go bad is checked.

Fruit is sun-dried in Asia Minor, Greece, Spain and other Mediterranean countries, and also in California, South Africa and Australia. The methods used vary, but in general the fruit is spread out on trays in drying yards in the hot sun. In order to prevent darkening, pears, peaches and apricots are exposed to the fumes of burning sulphur before drying. Plums for making prunes, and certain varieties of grapes for making raisins and currants, are dipped in an alkaline solution in order to crack the skins of the fruit slightly and remove their wax coating, so increasing the rate of drying.
Nowadays most foods are dried mechanically; the conventional method of such dehydration is to put food in chambers through which hot air is blown at temperatures of about 110°C at entry to about 45°C at exit. This is the usual method for drying such things as vegetables, minced meat, and fish.
Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated horizontal steel cylinder or by spraying them into a chamber through which a current of hot air passes. In the first case, the dried material is scraped off the roller as a thin film which is then broken up into small, though still relatively coarse flakes. In the second process it falls to the bottom of the chamber as a fine powder.
Where recognizable pieces of meat and vegetables are required, as in soup, the ingredients are dried separately and then mixed.
Dried foods take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to climbers, explorers and soldiers in battle, who have little storage space. They are also popular with housewives because it takes so little time to cook them.

The history of clinic nutrition, or the study of the relationship between health and how the body takes in and utilizers food substances, can be divided into four distinct eras: the first began in the nineteenth century and extended into the early twentieth century when it was recognized for the first time that food contained constituents that were essential agents. Near the end of this era, research studies demonstrated that rapid weight loss was associated with nitrogen imbalance and could only be rectified by providing adequate protein associate with certain foods.
The second era was initiated in the early decades of the twentieth century and might be called "the vitamin period". Vitamins came to be recognized in foods, endeficiency syndromes were described. As vitamins became recognized as essential food constituents necessary for health, it became tempting to suggest that every disease and condition for which there had been no previous effective treatment might be responsive to vitamin therapy. At the point in time, medical schools started to become more interested in having their curricula integrate nutritional therapies in medicine. Reckless claims were made for effects of vitamins that went far beyond what could actually be achieved from the use of them.
In the third era of nutritional history in the early 1950's to mid-1960's, vitamin therapy began to fall into disrepute. Concomitant with this, nutrition education in medical schools also became less popular. It was just a decade before this that many drug companies had found their vitamins sales skyrocketing and were quick to supply practicing physicians with generous samples of vitamins and literature extolling the virtue of supplementation for a variety health-related conditions. Expectations as to the success of vitamins in disease control were exaggerated. As is known in retrospect, vitamin and mineral therapies are much less effective when applied to health-crisis conditions that when applied to long-term problems of nutrition that lead chronic health problem.
