Some people seem to have unusual memories. Zheng Aiqiang, a "memory athlete" on TV show Super Brain, can remember 2,660 numbers in just one hour!

    You would think people like him must have special brains. But according to a recent study by researchers from America and Holland, the brain structure (结构) of ordinary people and 23 of the world's leading memory athletes shows no difference.

    Good memories can be trained. New research in the magazine Neuron suggests that a person will get a super memory with just six weeks of hard training.

    Researchers found that a technique (技巧) called loci, invented by the ancient Greeks, can greatly help improve memory.

    By using loci, you are using your imagination to improve the brain's memory networks. You can link (关联) something you need to remember with a place that you know very well. For example, to remember a list of numbers, imagine yourself walking through your house. Each thing is linked to a number. For example, zero could be the handle on the door and five could be the painting on the wall.

    In one study, some ordinary people were given 20 minutes to remember 72 nouns. At the beginning, they could only remember 26 words, but when they were taught loci, they could remember 62 words.

"Not everyone can become a memory winner. But everyone using the technique can improve his memory greatly," said Boris Konrad, one of the researchers in the study.

    Why do we like drinking water from plastic bottles? Some people think it is healthy and clean. Others drink bottled water because it's easy--you can carry it around with you. In hot countries, like Greece, we often buy bottles of cold water in the summer.

    However, making tots of plastic is not a good idea for many reasons. First of all, we need a lot of oil for plastic products. We usually use oil as a source(资源) of energy. If we reduced the number of bottles we made, we wouldn't need so much oil. Plastic bottles also pollute the environment. If we recycled all our plastic bottles, we wouldn't need so much space for rubbish dumps. But in Greece, we don't recycle much of the plastic we use. In 2006, Greeks recycled only about 10% of plastic waste. The rest became rubbish on land and in rivers and seas.

    So next time you want to throw away a plastic bottle in the litter bin, stop and think. If you recycled it, you would help the environment. But what can you do when there isn't a recycling bin near you? Well, there are lots of useful ways that you can use your bottles again. For example, an empty bottle makes a great piggy bank for your pocket money, and if you cut a bottle in half, you will have a plant pot. Go green! You can make a difference.

One weekend, my husband suggested we cook together. I had spoken to my mother earlier that day on the phone. I had told her about our life. She yawned(打哈欠) and we said 1 to one another. 

I didn't know then that just 16 hours later, my mother would die. 

My mother was my best friend. After she died, I felt 2 . She was the only person I wanted to 3 . The only person who could help me was the one who was missing. 

My mother gave me many things, 4 she had never taught me how to cook. She liked to eat more than cook. She loved to eat fish pie and 5 it to us for dinner. Almost every week, she would 6 a prepared fish pie. Then she would bring it home and make her own white sauce. 

My mother 7 taught me how to make a white sauce, and I never wanted to ask her. Since she was gone, I would have to teach 8 .

So this became my focus. For the first few weeks, I survived (生存) on cheap food. But one night, a fish pie mix 9 my eye at the store. 

When I got home, I 10 myself in front of our electric stove. Armed with a 11 , I tried to teach myself to make a white sauce. 

Halfway through the recipe, I couldn't believe it- I had made a white sauce on my own! Then I remembered: I had always 12 fish pie. 

Admiring my sauce, I wondered13 I wanted to make a dish I had hated for 25 years. Why was it suddenly so important?

I poured the sauce over the fish. Then I ate the pie. I realized that the act of 14 calmed me down. 

It helped me find15 .

Without classes and exams, the summer vacation is an ideal time for Australian kids. For me, Nancy, it means much more than not going to school. It is also a golden chance to spend time with my family because I have little time with them during the school year.

Last summer vacation I travelled with my family to the Hawkes bury River in Western Sydney. It was one of the most unforgettable summer vacations in my life.

Staying by the river helps us escape from the hot weather and noise of the city. Every day, my family and I got up early to go swimming in the cool water. In the morning, we all took part in a big game. We enjoyed water— skiing, wakeboarding(尾波滑水) and other activities. These activities made our family feel closer.

In the warm afternoon, we peacefully read books on hammocks hung among trees by the river. The days always ended with a campfire. We sat around the fire, talking and laughing.

The river is a perfect place for people to forget about all the stresses(压力) of life and simply enjoy the moment. To me, it is the best place to spend time together with my family. I can't help thinking about those days again and again although so many months has passed.

Good morning! My name is Simon King. Simon is my 1 name. And King is my last name. I am a student in No. 5 2 in Changsha, China. My favorite color is 3 . I have a blue telephone and a blue ruler. My favorite number is 4 . 863-6698 is my 5 number. You can 6 three sixes in it.

My friend John is an English boy. He 7 a student in my school. He is in No. 2 Middle School. Yellow is his favorite 8 . His jackets, rulers and pens are yellow. He likes blue, 9 . His cup is blue. He likes the number nine. What's his phone number? It's 599-9368.

Do you have a(n) 10 ? What is his or her name?
