A Robot Fish has been developed by National University of Singapore’s researchers from the Department of Electrical & Computer Engineering．This robot fish has movements which have been inspired by the movements of the carp（鲤鱼）．
There are various purposes that it can be used for．It can help in underwater archaeology （ 考古学 ）．For example, it can enter a sunken city where human divers cannot enter．Just like a fish , it can also look at all the comers of particular wreckage．This robot can also be used for general purposes such as detection of leakages in a pipeline or for laying down communication cables across oceans．It also has possible military uses．
In order to copy carp movements, Mr．Fan studied the movements of the fish for around 3 months．He studied all the different movements of carp using different cameras and then converted these movements mathematically to transfer this data to the robot using many actuators（驱动器）．
Professor Xu commented on the robot that the current models that copy fish movements are capable only of 2D movements which limits their capability as they are not able to dive into water．He said that his model is the first model with 3D movements which allows it to dive as well as float with the help of its fins, just as a normal fish would do．Hence, this fish model robot has much greater movement capability．It would be much harder for enemies to detect as compared to traditional ones when used for military purposes．
The researches want to make their robot fish even smaller, more realistic while adding more sensors such as GPS and video camera to it．This will improve its autonomous 3D movement．They are also planning to test the fish by giving it more difficult tasks such as detecting various objects．

When I was growing up, I had an old neighbor named Doctor Gibbs. He didn't look like any doctor I'd ever known. He never yelled at us for playing in his yard, but was always very kind.
When Doctor Gibbs wasn't saving lives, he was planting trees. He had some interesting theories about planting trees. He believed in the principle: "No pain, no gain". He hardly watered his new trees, an attitude which flew in the face of conventional wisdom.
Once I asked why and he told me that watering plants spoiled them because it made them grow weaker. He said you had to make things tough for the trees so that only the strongest could survive. He talked about how watering trees made them develop shallow roots and how, if they were not watered, trees would grow deep roots in search of water.
So, instead of watering his trees every morning, he'd beat them with a rolled-up newspaper. I asked him why he did that, and he said it was to get the tree's attention.
Doctor Gibbs died a couple of years after I left home. Every now and then, I walked by his house and looked at the trees that I'd watched him plant some 25 years ago. They were tall and strong.
I planted a couple of trees myself a few years ago. Two years of attending these trees meant they grew up weak. Whenever a cold wind blew, their branches trembled. Adversity seemed to benefit Doctor Gibb's trees in ways comfort and ease never could.
Every night before I go to bed, I check on my two sons. I often pray that their lives will be easy. But lately I've been thinking that it's time to change my prayer. I know my children are going to encounter hardship. There's always a cold wind blowing somewhere. What we need to do is to pray for deep roots, so when the rains fall and the winds blow, we won't be torn apart.

Three years ago I failed a important exam in my life and became a student in an ordinary school. Disappointing as I felt at the shabby campus and the poorly-equipped classroom, we found the teachers patient and considerate. Besides, I enjoyed the friendly atmosphere on class. I decided to make best of it. I work hard and got along well with my teachers and classmates. Whenever I had difficulties, they were not helpful. Soon , I became one of the top student in my class, which greatly increased my confident and got me motivated.
My experience tells me that it is not what you are given but how you make use of it which determines who you are.

Then, a few years ago, I met Tony , 7. was in his thirties and quit his job as a civil engineer in New York City to walk across the United States.He wasn’t doing it for a cause as part of an organization. He was doing it 8. (simple) because he loved to walk and discover. The idea was back and I no longer had an excuse. We planned on averaging 20 miles a day and taking some days off 9.

Sometimes I really doubt whether there is love between my parents. Every day they are very busy trying to in order to pay the high tuition for my brother and me. They don’t act in the ways that I read in books or I see on TV. In their opinion, “I love you” is too for them to say. Sending flowers to each other on Valentine’s Day is even more out of .
One day, my mother was sewing a quilt. I sat down beside her. “Mom, I have a question to ask you. Is there between you and Dad?” I asked her in a very low voice. She didn’t answer immediately. She her head and continued to sew the quilt.
I was worried because I thought I had her. I was and I didn’t know what I should do. But at last I heard my mother say the following words:
“Susan,” she said thoughtfully, “Look at this thread. Sometimes it , but most of it disappears in the quilt. The thread really makes the quilt . If life is a quilt, then love should be a thread. It can hardly be seen , but it’s really there. Love is .”
I listened carefully but I her until the next spring. At that time, my father suddenly seriously. My mother had to stay with him in the hospital for a month. When they returned from the hospital, they both looked _ . It seemed both of them had had a serious illness. After they were back, every day in the morning and dusk, my mother helped my father on the country road.
“Dad, how are you feeling now?” I asked him one day.
“Susan, don’t me.” He said gently. “To tell you the truth, I just like walking with your mom.” his eyes, I know he loves my mother deeply.
Once I thought love meant flowers, gifts and . But from this experience, I understand that love is just in the quilt of our life. Love is inside, making life strong and warm.
