Merchant and passenger ships are generally required to have a life preserver for every person aboard and in many cases, a certain percentage of smaller sizes for children. According to United States requirements, life preservers must be simple in design, reversible( 可翻转的), capable of being quickly adjusted to fit the uninitiated individual, and must be so designed as to support the wearer in the water in an upright or slightly backward position.
Sufficient buoyancy(浮力) to support the wearer should be retained by the life preserver after 48 hours in the water, and it should be reliable even after long period of storage. Thus it should be made of materials resistant to sunlight, gasoline, and oils, and it should be not easily set on fire. The position in which the life preserver will support a person who jumps or falls into the water is the most important thing, as is its tendency to turn the wearer in the water from a face-down position to an upright or slightly backward position, with his face clear of the water, even when the wearer is exhausted or unconscious.
The method of adjustment to the body should be simple, and self-evident to uninitiated individuals even in the dark under the confused conditions, which follow a disaster. Thus, the life preserver should be reversible so that it is nearly impossible to set it on wrong. Catches, straps, and ties should be kept to a minimum. In addition, the life preserver must be adjustable to the wide variety of shapes and sizes of wearers, since this greatly affects the position of floating and the self-righting qualities. A suitable life preserver should also be comfortable to wear at all times, in and out of the water, not so heavy as to encourage to take it off on shipboard while the ship is in danger, nor so burdensome that it hinders a person in the water while trying to swim.

One day, when I was working as a psychologist(心理学家) in England, a young boy showed up in my office. It was David. He kept walking up and down restlessly, his face pale, and his hands shaking slightly. His head teacher had introduced him to me before. “This boy has lost his family,” he wrote. “He is understandably very sad and refuses to talk to others, and I’m very worried about him. Can you help?”
I looked at David and showed him to a chair. How could I help him? There are problems which psychology doesn’t have the answer to, and which no words can describe. Sometimes the best thing one can do is to listen openly and silently. And I would do in this way.
The first two times we met, David didn’t say a word. He sat there, only looking up to look at the children’s drawings on the wall behind me. I suggested we play a game of chess. He nodded. After that he played chess with me every Wednesday afternoon—in complete silence and without looking at me. It’s not easy to cheat in chess, but I admit I made sure David won once or twice.
Usually, he arrived earlier than agreed, took the chess board and pieces from the shelf and began setting them up before I even got a chance to sit down. It seemed as if he enjoyed my company. But why did he never look at me?
“Perhaps he simply needs someone to share his pain with,” I thought. “Perhaps he senses that I respect his suffering.” Some months later, when we were playing chess, he looked up at me suddenly.
“It’s your turn,” he said.
After that day, David started talking. He got friends in school and joined a bicycle club. He wrote to me a few times, about his biking with some friends, and about his plan to get into university. Now he had really started to live his own life.
Maybe I gave David something. But I also learned that one—without any words—can reach out to another person. All it takes is a hug, a shoulder to cry on, a friendly touch, and an ear that listens.When he first met the author, David_________.
| A．felt a little excited | B．walked stubbornly |

| A．needed to share pain with the author |
| B．wanted to ask the author for advice |

| A．He recovered after months of treatment. |
| B．He liked biking before he lost his family. |

What made David change?
| A．His teacher’s help. |
| B．His exchange of letters with the author. |

The Healthy Habits Survey shows that only about one third of American seniors(年长者) have correct habits. Here are some findings and expert advice.
1.How many times did you brush your teeth yesterday?
·Finding：About 33% of seniors brush their teeth only once a day.
·Step：Remove the 300 kinds of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.
2.How many times did you wash your hands or bathe yesterday?
·Finding：Seniors, on average, bathe fewer than 3 days a week. And nearly 30% wash their hands only 4 times a day—half of the number that doctors advise.
·Step：We touch our faces around 3,000 times a day-often inviting germs（病菌）to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.
3. How often do you think about fighting germs?
·Finding：Seniors are not fighting germs as well as they should.

You may think that sailing is a difficult sport, but it is really not hard to learn it．You do not need to be strong．But you need to be quick．And you need to understand a few basic rules about the wind.
First, you must ask yourself, “Where is the wind coming from? Is it coming from ahead or behind or from the side?” You must think about this all the time on the boat．The wind direction tells you what to do with the sail.
Let's start with the wind blowing from behind．This means the wind and the boat are going in the same direction．Then you must always keep the sail outside the boat．It should be at a 90° angle (角度) to the boat．Then it will catch the wind best.
If the wind is blowing from the side, it is blowing across the boat．In this case, you must keep the sail half way outside the boat．It should be at a 45° angle to the boat．It needs to be out far enough to catch the wind, but it shouldn't flap (摆动)．It shouldn't look like a flag on a flagpole．If it is flapping, it is probably out too far, and the boat will slow down.
Sailing against the wind is not possible．If you try, the sail will flap and the boat will stop．You may want to go in that direction．It is possible, but you can't go in a straight line．You must go first in one direction and then in another．This is called tacking．When you are tacking, you must always keep the sail inside the boat.What should you consider first while sailing?
| A．Sailors' strength. | B．Wave levels. |
| C．Size of sails. | D．Wind directions. |
What does the word “It” underlined in Paragraph 4 refer to?
| A．The boat. | B．The sail. |
| C．The wind. | D．The angle. |
What do you have to do when sailing against the wind?
| A．Move in a straight line. | B．Allow the sail to flap. |
| C．Lower the sail. | D．Tack the boat. |
Where can you probably find the text?
| A．In a popular magazine. | B．In a tourist guidebook. |
| C．In a physics textbook. | D．In an official report. |
In 1978, I was 18 and was working as a nurse in a small town about 270 km away from Sydney, Australia. I was looking forward to having five days off from duty. Unfortunately, the only one train a day back to my home in Sydney had already left. So I thought I’d hitch a ride (搭便车).
I waited by the side of the highway for three hours but no one stopped for me. Finally, a man walked over and introduced himself as Gordon. He said that although he couldn’t give me a lift, I should come back to his house for lunch. He noticed me standing for hours in the November heat and thought I must be hungry. I was doubtful as a young girl but he assured (使……放心)me I was safe, and he also offered to help me find a lift home afterwards. When we arrived at his house, he made us sandwiches. After lunch, he helped me find a lift home.
Twenty-five years later, in 2003, while I was driving to a nearby town one day, I saw an elderly man standing in the glaring heat, trying to hitch a ride. I thought it was another chance to repay someone for the favor I’d been given decades earlier. I pulled over and picked him up. I made him comfortable on the back seat and offered him some water.
After a few moments of small talk, the man said to me, “You haven’t changed a bit, even your red hair is still the same.”
I couldn’t remember where I’d met him. He then told me he was the man who had given me lunch and helped me find a lift all those years ago. It was Gordon.The author(作者) had to hitch a ride one day in 1978 because____________ .

How many of us have heard that question, "Where was GOD when the World Trade Center(世贸中心) and the Pentagon(五角大楼) were attacked?" Well, I know where my GOD was the morning of September 11, 2001, and He was very busy!
He was trying to discourage anyone from taking these flights. Those four flights together held over 1000 passengers and there were only 266 aboard.
He was on 4 commercial flights giving frightened passengers the ability to stay calm. Not one of the family members who were called by a loved one on one of the hijacked(被劫持的) planes said that passengers were screaming in the background. On one of the flights he was giving strength to passengers to try to overtake the hijackers.
He was busy trying to create obstacles(阻碍) for employees at the World Trade Center. After all, only around 20,000 were at the towers when the first jet hit. Since the buildings held over 50,000 workers, this was a Miracle in itself. How many of the people who were employed at the World Trade Center told the media that they were late for work or they had traffic delays.
He was holding up 2-110 story buildings so that 2/3 of the workers could get out. I was so amazed that the top of the towers didn't fall when the jets crashed. And when they did fall, GOD made them fall inward, as many more lives would have been lost.
So when anyone asks, "Where was your GOD on September 11," you can say "everywhere"! And yes, although this is without a doubt the worst thing I have seen in my life, I see God's miracles in every bit of it. I can't imagine going through such a difficult time and not believing in GOD – life would be hopeless. So shines a good deed in a weary world!In what way the author tried to prove his point in the passage?
