Have you ever noticed that people have thinner arms and legs as they get older? As we age it becomes harder to keep our muscles healthy. They get smaller, which reduces strength and increases the possibility of falls and fractures . New research is showing how this happens and what to do about it. A team of Nottingham researchers has already shown that when older people eat, they cannot make muscle as fast as the young. Now they've found that the ability to prevent muscle breakdown is reduced with age. When older people eat, they don't build enough muscle with the protein in food; also, the insulin fails to shut down the muscle breakdown that rises between meals and overnight. Normally, in young people, insulin acts to slow muscle breakdown. The research just published compared one group of people in their late 60s to a group of 25-year-olds, with equal numbers of men and women. "We studied our subjects first -- before breakfast -- and then after giving them a small amount of insulin to raise the hormone to what they would be if they had eaten breakfast," Professor Rennie said. " The results were clear. The younger people's muscles were able to use insulin we gave to stop the muscle breakdown, which had increased during the night. The muscles in the older people could not. In the course of our tests, we also noticed that the blood flow in the leg was greater in the younger people than the older ones," added Professor Rennie. However, scientists think that weight training may reactivate muscle blood flow and help retain muscles for older people. "In fact, doing exercise three times a week over 20 weeks reactivates the leg blood flow responses of older people. They became identical to those in the young," said Professor Rennie. Which of the following is TRUE according to the passage? A) Older people have fewer muscles than the young. B) The more insulin we have, the stronger our muscles are. C) The insulin in older people's muscles could not stop muscles breakdown. D) There is less blood in older people's body.

There is no question that fewer teenagers are on the roads in the US. In 1978, 50% of 16-year-olds had got their first driving licence. In 2008, according to the US Transportation Department, it was just 30%. The number of those aged 19 and under with driving licences has also been _ since 1978, when 11, 989, 000 had licence. In 2010, it was 9, 932, 441, or 4.1% of American drivers. In the UK, 683, 273 teenagers have driving licences- just 1.85% of total licence holders, according to Department of Transport figures from September 2010. But the decline in the US may have more to do with tougher tests and the introduction of the new rule in many states, which force drivers aged under 16 to be with licensed drivers of 21 years and older when driving. In recent years, the annual number of journeys being made by American drivers of all ages has declined clearly for the first time ever. Car use began falling in 2007, when average petrol prices almost doubled to $4.12 a gallon, and the economy became worse. But there are signs that it is getting back to normal and American remains a country on wheels. It has a higher number of cars per head of population than any other country in the world. "Cars will always be a popular means of transportation in America. You have to take into consideration some places don't have access to public transportation. Cars are the only way some people can get around," says Kristin Nevels. This makes driving necessary in some rural states, where about twice as many teenagers are on the road than in big cities. In recent years cars are used less than before mainly because of _ . A) traffic jams B) harder tests C) expensive petrol D) worst economy

Ques:Six years ago, I walked into a local animal shelter on a cold, rainy day. Although my house was already full of cats and dogs, I still couldn't resist an occasional visit to the shelter. This time as I was walking down the row of pens full of barking dogs I noticed a small boy looking into one of them. He had a malnourished looking body and a bony face with a big nose sticking out of the middle of it. He was looking at a small, golden dog. Its bony ribs were showing and its thin tail was folded between its legs. It wasn't begging for attention like the other puppies but was hiding in the corner instead. The boy looked up at me with sad eyes and asked what was wrong with it. "It was probably abused and abandoned", I said. "That is why it is so scared." The boy immediately turned to an older lady and said, "Grandma, I want this one." The old woman smiled and walked to the front desk to fill out the adoption forms. I followed and asked about the boy. I found out that he'd had a rough start in life too. She had just gotten custody of him after the state had taken him from his parents. She had hoped getting a dog would make it easier on him. I looked back at him, holding his scared puppy, and said a prayer for them both. It was yesterday. I was driving down the road enjoying a gloriously sunny, spring day. Then in a green front yard I saw the boy. His teenage body was tall and strong. His nose no longer seemed big but fit well into his smiling face. He was throwing a ball to a healthy, happy dog with shining golden hair. His little act of love and kindness had indeed gone a long way. It had saved a dog's life, healed his own heart, and given this middle-aged man fresh hope for us all. The author entered the animal shelter because _ . A) he loves dogs and pets B) it was too cold outside C) he wanted to buy a dog D) he wanted to see the boy
