The huge explosion at Krakatau was the result of two different factors. One was that the volcano had not broken out for some time and so at the very center of the volcano there was a huge plug of lava, which acted like a cork(塞子) in a bottle, stopping the pressure below from being released(释放). The second factor was that ocean water entered the very centre of the volcano as the explosions became more violent. This caused superheated steam to build up enormous pressure and this was finally released in the largest explosion of all on August 27, 1883. The sudden release of the pressure sent huge amounts of ash, rock and dust into the sky. Some of the ash rose 80km into the air and traveled around the Earth causing brightly coloured sunsets for several years.
Krakatau almost disappeared; for many years after this explosion, it remained very quiet. However, there was still activity going on under the sea and on 25 January, 1925, a small volcanic cone appeared above the surface of the water. This new volcano was named Anak Kmkatau, or Child of Krakatau. Over the following years, the size of the island grew larger, by 1959, the island was 300 metres above the surface of the sea. The volcanic activity has continued and the latest eruptions were in 1995.
There is no doubt Krakatau will continue to grow and there is also strong evidence that at some point in the future there will be another violent explosion. Krakatau is in a part of the world where the surface of the Earth is unstable and is always moving and cracking. If, in the future, another “cork” becomes fixed in the centre of the volcano, the pressure will build up. A series of a smaller explosions will allow sea-water into the centre of the volcano and once again the result will be a terribly destructive explosion.

Yesterday I started the Year of Giving, my first day of a year-long journey into exploring the act of giving and the meaning of charity. I chose December 15 as the starting date, which marked three years since my mother died from heart disease. She was one of the most generous people that I have ever known. She always thought of others first and certainly serves as an inspiration to me.
I had a rather busy day yesterday, ironic (具有讽刺意义的) for someone who is unemployed right now. In the morning I went to the gym, and unsuccessfully got the phone call from the unemployment office for some job searching. Before I knew it, it was noon. I grabbed a quick lunch and rushed down to a meeting. On my way to Connecticut, I wondered if I would see someone that I would feel forced to give my first $ 10 to. I was running late and decided to do it afterwards.
After the meeting I had about half an hour to find the first person of my Year of Giving! I decided to check out DuPont Circle. I had met a guy there named Jerry once and thought he would willing accept my $ 10. He wasn’t there, but I did see a man sitting by himself who looked really lonely, so I approached him. Now I had to figure out what I was going to say, I think I said something like, “Hi, can I sit down here?” “I would like to know if I could give you $ 10?” He asked me to repeat what I had said, I did, then he looked at me funny, got up and left.
I then started walking south where I spotted a man standing by the bus stop on Connecticut Ave. He appeared to be in his 60s. I don’t know what drew me to him, but I thought I would make my second attempt. I was a bit nervous and asked him which bus came by that stop. Then I explained that I was starting a year-long project to give $ 10 to someone every day and that I wanted to give my $ 10 for today to him. The gentleman, I later found out that his name was Ed, responded without hesitation that he could not accept my offer and that there were many people more deserving the money than him. This was exactly one of the things that I hoped would happen. People would think of others before themselves. The author set the starting date on December 15 to ____.
| A．help the charity |
| B．remember his mother |
| C．make an explosion |
| D．fulfill a wish if his mum |
In the author’s first attempt to give away the money, ____.
| A．he was considered ridiculous |
| B．he hesitated for a long time |
| C．he was forced to donate the money |
| D．he had no time to take action |
In the author’s second attempt, the gentleman refused his offer because ____.
| A．he didn’t need other’s help |
| B．he thought more for others |
| C．he didn’t care about money |
| D．he wanted to get more money |
We can refer that the author was inspired by ____.
| A．true friendship | B．his own kindness |
| C．generous donations | D．human’s good nature |
The first day of school, our professor introduced an old lady Rose to us.
“Why are you in college at such an age?” I asked her. She replied, “I always dreamed of having a college education and now I’m getting one!” We became friends quickly.
At the end of the term I invited Rose to make a speech to our football team. I’ll never forget what she taught us. She said, “There are some secrets of staying young and being happy. You have to laugh and find humor every day. You must have a dream. When you lose your dreams, you will die. There is a huge difference between growing old and growing up. Anybody can grow older. That doesn’t need any talent or ability. To grow up, you must always find the opportunity in change. Have no regrets. The people who are afraid of death are those with regrets.”
At the end of the year, Rose finished her college. One week after graduation, Rose died peacefully in her sleep. We would always remember the great woman.

Many people go to school for an education. Some learn languages, history, math and other subjects. Others go to school to learn a skill. School education is very important and useful. Yet no one can learn everything from school. A teacher cannot teach his students everything they want to know. So much more is learned outside school by the students themselves.
Great people before us didn’t get everything from school. Their teachers only showed them the way. Edison didn’t even finish school. But they were all so successful because they knew how to study. They read books that were not taught at school. They would ask many questions as they read. They worked hard all their lives. Above all, they knew how to use their heads.

What are you going to do if you are in a burning house? How will you escape? Do you know how to save yourself? Please read the following passage.
Escaping from a fire is a serious matter. Knowing what to do during a fire can save your life. It is important to know the ways you can use and show them to everyone in the family, such as stairways (楼梯) and fire escapes, but not lifts.
From the lower floors of the buildings, escaping through windows is possible. Learn the best way of leaving through windows with the least chance of serious injury (伤害).
The second floor window is usually not very high from the ground. An average(平均高度的) person, hanging by the finger-tips (手指尖) will have a drop of about six feet to the ground. It is about the height of an average man. Of course, it is safer to jump a short way than to stay in a burning building.
Windows are also useful when you are waiting for help. Be sure to keep the door closed. Or smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked (泄露) into the room.
On a second or third floor, the best windows for escape are those which open onto a roof (屋顶). From the roof a person can drop to the ground more safely. Dropping onto hard ground might end in injury. Bushes(灌木丛) and grass can help to break a fall.
