Article: I once experienced an unforgettable trip to Gloucester to see some of the world's most beautiful and exciting animals in their own habitat , the North Atlantic Ocean. After a long trip by bus, we got on the ship. After a while, we stopped and everyone on the ship started to shout because we saw a humpback whale . It was wonderful. Sometimes, whales came so close to the ship that you thought you could easily touch them. While we were watching the whales, a guide was giving us some information about them. She told us that we saw only two kinds of whales -- 50-foot humpback whales (singing whales) and 70-foot fin back whales (the second largest whales on earth). She also said we could easily recognize a whale by its tail because every whale has a different kind of tail just like people have different fingerprints. They all have names, and on this trip, we saw "Salt" and "Pepper", two whales named by a biologist and a fisherman. They were swimming together all the time. I took twenty-seven photos, but it was very hard to take them because the whales were quick and stayed on the surface of the ocean just for a short time. It was really something. It was one of the chances that a person hardly ever experiences in life, but I had that chance.
Answer: an unforgettable trip to watch whales

Article: My first visit to London was one and a half years ago. It was a wonderful trip. I stayed in the city for three weeks, and I had many impressions. I visited all the famous places. I'd like to tell you about some of the places I visited in this beautiful city. First, I went to the Tower of London, and I want to say that it is a very interesting historical place. I found out that a long time ago, it was a prison. Later it became a castle for the royal family. Or maybe it is the reverse; I'm not sure, but later they left this place and lived in Buckingham Palace and Kensington Palace. I also enjoyed visiting the House of Parliament and Westminster Abbey, two very popular places for tourists. They are very old and beautiful. The Abbey is built in a kind of Gothic style; it is fantastic. In London, you can also enjoy nature. There are many parks such as Hyde Park, Green Park, and Holland Park. These parks are wonderful green, quiet places where you can relax and escape the noise of the city. Trafalgar Square is a popular place for students and other young people. You will find lots of pigeons there. If you have time, you can feed them and they will be very happy. You can buy special food for them, but be careful! Tons of birds are going to surround you if you feed them. Another very special place in London that I like is St. Paul's Cathedral which was designed by Sir Christopher Wren. I also was impressed with the museums in London. They're very popular. I found them interesting because you can learn about the history of England. I had a wonderful time in London. I really liked it because it is a city that is rich in history.
Answer: recall his/her first travel to London

Article: Dear Alice, You really have two different questions here, so we'll discuss them one at a time. Your problems at school may be a result of a number of things . You don't say much about how these classmates get along with each other. It's possible that all the students are feeling a little cautious in the first term. It's also possible that the others are unkind. If this is so, you have to find out why you are the class "outsider". In your letter you say you often offer to help others with their work. Is it possible that your classmates don't understand your offers? Could it seem that you were trying to " buy" friends with these offers? Is it possible that you took no notice of your classmates when you had your good friends near you ? They may have felt hurt at that time. It may take a time for them to believe in you if so. Try to ask one classmate directly what the problem is. If you hear a negative answer, at least you'll know what to do. Yours truly, Shelia
