It is no wonder many of us find it difficult to have a sufficient amount of sleep. But will sleeping more on the weekend make up for hours of lost snoozing ? One sleep expert, W. Christopher Winter raised the question. Sleeping binge Getting eight hours of shut-eye each night is generally recommended, but many people don't. As the week rolls from Monday to Friday, they accumulate a sleep debt. Spending a few extra hours in bed on a Saturday morning, people assume, will help them " catch up" on lost sleep. They're likely right, " Nobody knows how long the horizon is, probably a few nights, but studies show that recovery sleep in the short term does work," says Dr. Winter, a member of the American Academy of Sleep Medicine. Sleep banking Recent data suggests that banking sleep in advance of a long night can actually offset upcoming sleep deprivation . If you knew you were going to have to stay up all night on a particular day, for example, you could sleep for 10 hours a day for multiple days before the event, and be fine, Dr. Winter says. Just plan ahead. Routine naps A scheduled nap is healthier than catching up on or banking sleep. " Because sleep extension can make you feel groggy , I always recommend a short nap [if a person feels they need it ], at the same time, every day," says Dr. Winter. He adds that 25 minutes is ideal. " When you schedule a short nap, your body anticipates it and slows down, without falling into a deep dream sleep," he says. That refreshing, scheduled break is better than an occasional weekend lie-in. " The body likes routine," he says, " When it's prepared, it works more efficiently."

Read the following article and select the best answer. Article: The average British 22 year-old has more than 1,000 online friends on sites like Facebook, compared to those in their fifties who have fewer than 20, according to a new study. The "Facebookgeneration gap" has been highlighted in a new piece of research which shows that the average 22 year-old claims to have 1,000 or more friends on sites like Facebook. People in their twenties have more than 50 times as many digital friends as those who are over 50 years old, despite the popularity of sites like Facebook with the older generations, says a study conducted by consumer research group Intersperience. The news comes during the same week Facebook's second-in command, Sheryl Sandberg, is visiting the UK to deliver a speech at the London School of Economics. Facebook's chief operating officer is going to speak about how the social web has transformed people's friendships and relationships. The survey found that there was a clear link between people's age and the number of online friends they have.The researchers found that those aged 13 to 16, have an average of 450 friends on social networks, with girls having slightly more friends that boys.People in their thirties tend to have between 100 and 200 friends, while those in their forties have between 50 and 100. However, those using sites such as Facebook over the age of 50, tended to have 20 or less friends.The oldest person surveyed was 70 years old. Paul Hudson, Intersperience's chief executive, said: "Our research underlines fundamental changes taking place in British society as a result of finally entering the digital age.Half of the UK population are on Facebook now.In a social media context, a 'friend' means something different to a 20 year old than to a 50 year old." He added: "Social networking activity is just one example of how different groups are adapting to the digital age at different paces.In this case, age is the determining factor - however in other instances it is not." Question: Which is the determining factor in social networking activity? - Gender - Age - Relationship - Pace

Q: Read the following article and select the best answer. Article: Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe. Previous studies have linked high exposure to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of "moderate" quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure. The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

Q: Read the following article and select the best answer. Article: After commuting, cooking dinner and doing household chores, the average parent has just 30 minutes to devote to their children in the evenings, according to a new study. One in four working parents worry that half an hour simply isn't enough, while almost half fret that they aren't a good enough parent during the week. However, parenting experts believe just 12 minutes a day may be enough for mothers and fathers to fully _ with their child -- as long as they ask the right questions. Child psychologist Dr Claire Halsey said asking a series of open-ended questions can help improve parents' relationship with their children. Among the questions recommended in the research are: "How many times have you smiled today -- what made you laugh?"; "Can you act out what you did at breaktime?"; "Who is taller -- mummy or your teacher?" and "What are the names of the toys you played with today?" Parents of older children are advised to start up a conversation with: "I've got a great story for you but I want one in return... you first!" or "Tell me some school gossip ... _ !" Dr Halsey, working with the makers of Ribena Plus, who commissioned the research, said: "There is no one as tough on their own parenting skills as a parent -- but this study shows there is no need for parents to be so harsh. It's hard for working parents to juggle all their responsibilities and it can feel like guilt is simply a parent's lot -- but it's absolutely not. By using clever tactics such as a little preparation alongside use of open-ended questions -- such as 'Tell me what the best bit about your day was?' -- parents can reduce the time worrying about chores and work and spend more time learning about their children's day." Question: Which of the following open-ended questions is for a three-year-old child? - Where are you off to with your friends this weekend? - Who played the best in your football match today? - What science project are you doing at the moment and can I help with it? - What are the names of the toys you played with today?
