The World Health Organization (WHO) planned to study the relationship between the eating habits of the people and the disease. Two doctors were chosen to make the study. They flew to Africa south of the Sahara and during the next two months visited ten countries. They found that serious diseases of poor eating, often mistaken for other diseases, existed in all parts of Africa. The diseases were similar and could therefore all be named kwashiorkor. The diseased children are usually from one to four years old. As the illness progresses, the child's stomach becomes swollen by liquid collecting in the body. The skin changes color and may break out in open sores . The hair changes color and starts to fall out. The patient loses all interest in his surroundings and even in food, and becomes so weak that he wants to lie down all the time. Stomach liquids are no longer produced. The doctors reasoned that kwashiorkor was found in the young children of this age in many parts of Africa because of lack of milk or meat. Their mothers, after stopping their breastfeeding, gave them foods full of starches instead of greatly needed proteins. They found that the addition of milk to the food of the children suffering from kwashiorkor saved many lives. The unbelievable thing about kwashiorkor is that the very existence of the disease--which has been killing thousands of children for centuries--was not even recognized in Latin America as recently as ten years ago. The deaths of those children were mistakenly listed as due to other diseases. It was the WHO's work in Africa that led to the discovery of the problem in Central America. It is difficult to discover kwashiorkor because _ . A) it has no symptoms at all B) it is hard to identify signs of it C) it doesn't last long enough for careful observation D) it is hardly different from other diseases

Everyone agrees that it's necessary to reduce carbon emissions around the world. There is less agreement over exactly how nations should go about achieving a more carbon - free planet. Thus, the environmental equivalent: cap - and - trade carbon emissions, or place a carbon tax on all users? With cap - and - trade programs, governments limit the level of carbon produced by an industry. Companies that hold their emissions below the _ can sell their remaining allowance on a carbon market, while companies that go beyond their limit must purchase credits on that market. Carbon taxes are more straightforward: a set tax rate is placed on the consumption of carbon with the idea that raising the price will encourage industries and individuals to consume less. At the moment, cap-and-trade has the upper hand, but doesn't defeat the tax just yet. Supporters of the tax argue that a cap - and - trade system would be too difficult to administer - and too easily gamed by industries looking to sidestep emissions caps. Cap-and-trade advocates contradict that like all other flat taxes, a carbon collection would relatively burden lower - income families, who spend a greater percentage of their income on energy than rich households. So which system will have a larger effect on carbon consumption? A 10% carbon tax might reduce the demand for carbon about 5 % or less, according to an analysis by the Carbon Tax Center, an environmental advocacy group. That may not be enough. Businesses and governments haven't figured out how the two competing systems can work together, but in the end, the world may need both. According to the cap - and - trade program, companies _ . A) are forbidden to produce carbon emissions B) are allocated the same amount of carbon consumption C) can sell their remaining allowance within their limits D) can sell the extra amount of carbon at a higher price

Thousands of teenagers will be able to transfer to a new wave of "studio schools" at the age of 14 to improve their chances of finding a job in UK. A dozen new-style schools are designed to act as a bridge to the workplace and cut the number of NEETs--young people not in education, employment or training. Under plans, schools will operate longer days and work outside standard academic terms. Each pupil will be expected to spend between four hours and two days a week on work placements with businesses linked to the school and teenagers will be assigned a personal coach to act as an academic "line manager". The reforms are put forward due to the fears that too many teenagers are now finishing full-time education lacking the skills needed to succeed in the workplace. According to a recent report, more than two-thirds of employers believe school and college leavers lack important "employability skills" such as customer awareness, while 55 per cent say they are unable to manage their time or daily tasks. And the number of NEETs has hit a record high, with almost one-in-five young people being left without a job or training place. The Department for Education will announce the establishment of 12 studio schools -- meeting the need of around 3,600 teenagers -- in areas such as Liverpool, Stevenage, Stoke-on-Trent and Fulham, west London. Each one, opening in 2012, will be linked to a series of local employers. Under plans, pupils will be able to transfer out of ordinary schools to attend them between the age of 14 and 19. The Government said all subjects would be taught "through projects, often designed with employers" -- with disciplines such as science being linked directly to local engineering firms or hospitals. Schools will operate a longer day to give pupils a better understanding of the demands of the workplace. Along with their studies, pupils will carry out work placements for four hours a week, rising to two days a week of paid work for those aged 16 to 19. They will also get the chance to take... Compared to ordinary schools, studio schools will offer the young more _ . A) interesting and lovely cartoons to make study easier B) chances to get future jobs with expert job training C) possibilities to make friends without going outside D) lessons helping them to be admitted to universities

Travis is the manager of G&G where he is responsible for forty employees and profits of over $2 million per year. He's never late to work. He does not get upset on the job. When one of his employees started crying after a customer screamed at her, Travis took her away. "Your working uniform is your shelter," he told her. "Nothing anyone says will ever hurt you. You will always be as strong as you want to be." Travis picked up that lecture in one of his G&G training courses, an education program that began on his first day and continues throughout an employee's occupation. The training has, Travis says, changed his life. G&G has taught him how to live, how to focus, how to get to work on time, and how to master his emotions . Most importantly, it taught him willpower. At the center of that education is an extreme focus on an all-important habit; willpower. Dozens of cases show that willpower is the single most important habit for a person's success. And the best way to strengthen willpower is to make it into a habit. "Sometimes it looks like people with great self-control aren't working hard--but that's because they've made it automatic," Angela Duckworth, one of the University of Pennsylvania researchers said. "Their willpower occurs without them having to think about it." The company spent millions of dollars developing programs of study to train employees on self-control. Managers wrote workbooks that serve as guides to how to make willpower a habit in workers' lives. Those courses arc, in part, why G&G has grown from a sleepy company into a large one with more than seventeen thousand stores and profits of more than $10 billion a year. Willpower will become a habit when employees can _ . A) focus on the profits B) benefit from the job C) protect themselves well D) control their feeling well
