　　New evidence shows why getting enough sleep is a top priority. Some 40% of Americans get less than 7 hours of shut-eye on week nights. "The link between sleep and health, and bad sleep and disease is becoming clearer and clearer." says Lawrence Alberstaine, a sleep expert at Harvard University. For example, sleep duration has declined from some 8 hours in the 1950s to 7 in recent years. At the same time, high blood pressure has become an increasing problem. Blood pressure and heart rate are typically at their lowest levels during sleep. People who sleep less tend to have higher blood pressure, heart attack, diabetes, weight gain and other problems.

　　Sleeping better may help fight off illness. "When people are sleep-derived, there are higher levels of stress hormones in their bodies which can decrease immune function." says Doctor Felice, of Northwestern University in Chicago. A university of Chicago study shows people who sleep well live longer. So say good night sooner and it may help you stay active and vital to a ripe old age.

　　Parents and teachers will tell you not to worry when applying for a place at a university. But in the same breath will remind you that it is the most important decision of your life.

　　The first decision is your choice of course. It will depend on what you want to get out of university, what you are good at and what you enjoy. The next decision is where to apply. Aim high but within reason. Do you have the right combination of subjects and are your expected grades likely to meet entry requirements? The deadline is January 15th. But it is best to submit your application early because universities begin work as soon as forms start rolling in.

　　The most important part of the application is the much feared personal statement. This is your chance to convey boundless enthusiasm for the subject. So economy of expression is foremost. Omit dull and ineffective generalities and make sure you give concrete examples.

　　Admissions officers read every personal statement that arrives. It is not convincing if you say you have chosen the subject because you enjoy it. You have to get across what it is about a particular area that has inspired you. They will look for evidence that you have reflected and thought about the subject.

　　Applicants should be honest. There is no point saying you run marathons, if you are going to be out of breath arriving at the interview on the second floor.

　　Q19. What is the first decision you should make in preparing to apply for a place at a university?

　　Q20. What is the most important part of the application?

　　Q21. What must applicants do in their personal statements?

　　It is widely believed that German invented the first car in 1885. It was actually a tricycle with a petrol motor at the rear. Soon, members of the royal family and other wealthy people took up motoring as a sport. Many of the early cars had 2 seats. There were no petrol pumps and few garages, so every driver had to be his own engineer for the frequent breakdowns.

　　By 1905, cars began to look like cars of today, with head lamps, wind screen, rubble tires and number plates. Henry Ford's Model T introduced in America in 1909 was cheaper because it was made on the assembly line. It brought cars closer towards the reach of ordinary people. With the popularity of the car, registration became a must in 1903 with the motor car act. Competency tests were introduced in 1935.

　　Today, the legal driving age for a car in the UK is 17. You are not allowed to drive a car unsupervised until you have passed a driving test. In 1958, Britain celebrated the opening of its first motor way – the Preston Bypass. Until then, no one really understood what a motor way was, not even the laborers who were building it. The bypass held a new era in motor travel and was greeted with excitement and optimism. Service stations came with the motor way and the legend of the transport cafe was born. Of course, the service station has diversified greatly. But whether it’s an English-cooked breakfast or a coffee and a sandwich, one thing has remained the same: the prices.

　　Q22. What does the speaker say about the first motor car?

　　Q23. What was the problem with the early cars in Britain?

　　Q24. Why did Henry Ford's Model T cars cost less?

　　Q25. What do we learn about the Preston Bypass?
