Three surfers rushed to save a man’s life after he was left drifting on a notorious stretch of water.
The men stayed with Greg Popple for 30 minutes and had to be rescued themselves by helicopter as the drama unfolded.
The 45-year-old had floated out on a body board near Hutchwns Point at 8:30 am. He found himself in trouble about half-a-mile from the shore and dangerously close to rocks. Surfers Graig Evans, 31, Robert Miles, 19, and Owain Daviees, 23, were risking their own safety to keep him floating for 30 minutes. Luckily a passer-by noticed what was going on and raised the alarm. Porthcawl Coastguard, Porthcaw Lifeboat and an RAF helicopter all took part in the rescue.
“The man who got into trouble was a body boarder-there was a big tide where he was,” said Joe Missen. “Three other surfers spotted he was in difficulty and he was going down. They kept him afloat because he was in a state of shock and out of energy. If Mr. Popple was closer to the rocks, it could have been a lot worse, but they managed to keep him from harm”.
Mr. Missen’s mum Alison, also part of the rescue team, said, “That part of the water is notorious for taking people out to nowhere”.
The three men had clocked off a night shift at Ford Motor Company shortly before the incident.
“I headed straight down to the beach for a surf, when I saw him flailing(揮動(dòng)). We just swam straight out to him and kept him calm while the help came”.
The four men were taken to the life boat house to recover, without injuries.

Baths and bathing have been considered of an important medical therapy to man. In Greece there are the ruins of a bath tub and water system built over 3 000 years ago. The Romans had warm public baths. In some public baths as many 3 000 persons could bathe at the same time.
Treating diseases by bathing has been popular for centuries. Modern medical bathing, or hydrotherapy, first became popular in Europe and by the late 1 700’s also became popular in the United States.
For many years frequent bathing was believed to be bad for one’s health. Ordinary bathing just to be clean was avoided, and perfume(香水) was used to cover up body and smell.
By the 1 700’s doctors began to say that soap and water were good for health. They believed that it was good for people to be clean. Slowly, people began to bathe more frequently.
In the United States ordinary bathing was slow to become popular. During the 18th and early 19th centuries, many Americans were known as “the great unwashed”. In one American city, for example, a person could only take a bath every 30 days! That was a law.
Frequency of bathing today is partly a matter of habit. People know that bathing for cleanliness is important to health. Doctors know that dirty bodies increase that chance of disease.    
Therefore in the United States people generally bathe often.

C
Have you noticed that the majority of human beings seem to focus on the negative? Bad news is often seen in the newspapers, television shows and magazines, but good news are often overlooked.
I saw a woman I was not very familiar with. She is a beautiful woman; every time I see her, I am struck by the smile on her face that can light up a whole room. So at one time I walked up to her and said, “You know, you are like liquid sunshine! Every time I see you, you give me so much joy.” I was not quite prepared for her reaction. She was blown away. Her eyes seemed about to shed tears, and she said, “That is so sweet! That is the nicest thing anyone has ever said to me!” It was as if nobody had ever told her how beautiful her appearance was. I was extremely moved by the moment I had shared with this woman.
Why not take notice of the positive and spread a little sunshine? When you are looking for beauty, you will begin to see it more and more. When you discover it, don’t be afraid to appreciate it. Not only will it make them feel good, it will make you feel good as well. I truly believe the saying, “What goes around, comes around.” When you show kindness and sincerity, you will receive it back. You may even discover — much to your surprise — that you become the friend of someone you would never have expected to get along with.
65. The woman had tears in her eyes because __________.
A. the man’s behavior was so rude
B. she was nervous about the man’s words
C. the man told her the fact she didn’t know
D. she was so excited at the man’s praise
66. Which of the following can take the place of the underlined sentence in the third paragraph?
A. The wise appreciate one another. 
B. Respect yourself, or no one else will respect you.
C. There is kindness to be found everywhere.
D. Everybody should learn to praise others.
67. The best title for the passage probably is _____.
A. Pay attention to the positive   B. Everyone likes to be praised
C. Spread a little sunshine       D. Each of us has good points
