[Q]: Article: They tell us when to get up or when we're running late for work and whether we are in danger of missing our favourite TV programme. But while our daily routines rely on clocks that tell us the time, science is discovering that our well-being is influenced by a very different kind of timepiece. Circadian rhythms---the human body's own internal clock---have a powerful influence on our health and behaviour. _ are programmed from birth and control functions ranging from temperature and blood pressure to sleep patterns. In recent years researchers have also discovered that this built-in mechanism can influence everything from the way we react to medicines to how well we learn music. The latest example, from experts at Harvard University in the US, shows that the human body clock can even dictate whether or not we are likely to tell the truth. Researchers found it was easier for people to fib in the afternoon because, as they were tired, the self control that would normally prevent them from lying started to break down. Tiredness made it harder to resist the temptation to tell lies---especially if it meant they got a financial reward at the end. "The body clock has a great effect on us all," says Professor Jim Horne from the Sleep Research Centre at Loughborough University. "Most people tend to feel good around late morning and then decline in the early afternoon. But the time most of us will feel our sharpest is between 6pm and 8pm. That's because sleepiness tends to build up throughout the day. By early evening our body clock kicks in to wake us up. One reason may be to ensure we get home safely. When our ancestors were coming home after hunting all day their internal clocks kicked in to get them home in one piece." So what effects do circadian rhythms have and what's the best time of day to take advantage of them?

[Q]: Article: Young women are more adventurous than young men when travelling abroad in gap years.One in three female backpackers visits more than three countries during a year out and travels alone, according to new research. By contrast, the majority of their male counterparts visit only one country and tend to travel in groups, says a survey by the Gap Year company, which provides information and services for students considering taking a year out. More women than men say that their prime reason for taking time off is to see the world and experience different cultures.Men are more likely to rank "having fun" higher on their list of _ .Women are more likely to value the challenge of a foreign trip, and many cited reasons such as learning a language and meeting new people. The more adventurous gap years taken by women seem to work to their benefit; more than three quarters of those surveyed have reported increased confidence, self-reliance and independence, whereas only half of the men had that experience. The research also shows that women are more likely to do voluntary work while travelling, with more than one in ten helping with teaching or development projects.One of the reasons given for this is a wish to see the country in an authentic light. A greater proportion of women than men face objections or criticism from their families over their gapyear plans.Among the men surveyed, lack of money is the main barrier to travel. Carolyn Martin, a doctor from London,is a typically confident female traveller.Starting in Cape Town, she travelled around southern Africa and Australia with a string of unusual and sometimes dangerous jobs. "I had one job chasing elephants off the runway in Africa by banging a stick against a pan," she recalled."It was OK but one day I did get chased by one." She said that she had travelled alone because "you meet more people".

[Q]: Article: Why must we pay taxes? The answer is that the government needs money for many things, for example to pay its soldiers, sailors and airmen, to build roads, bridges, offices, schools, etc and to buy goods from abroad; and only the people of the country can supply the money.One of the most important taxes is income-tax which a person pays according to the amount of his income-tax.Whether he is a businessman, a doctor, a lawyer, a shopkeeper, a miner, or anything else.This is called a "direct" tax, because it is paid in money direct to the government. Another tax is paid on goods such as watches, jewellery, new clothes, tobacco, wine, etc, when they are brought into a country, such a tax is paid as part of the price of these goods if they are later sold in shops.We call it "indirect" tax, because it is paid indirectly through the shopkeeper. People usually complain about having to pay taxes, but they forget that the money is spent on the things that they and their families need.We need policemen to catch thieves, to see that men obey the laws, to direct traffic, etc, and they must be paid what they earn; children need education and there must be schools and teachers; we want our streets to be kept clean, and the wages of men who do this kind of work have to be paid.Above all, the country must always be ready to defend itself against attacking enemies, and we cannot have an army without paying for it. Taxes, therefore, cannot be avoided.We buy our own food and clothes and pay for our own amusements, but there are several things that the State finds the money for, and that are necessary for us if our society is to continue.So we have no real cause to complain when we are asked to supply money to be spent for the good of ourselves and for our fellow-citizens.
