A fish that lives in America can live out of water for months at a time, similar to how animals got used to land millions of years ago, a new study shows.
The Mangrove Rivulets, a kind of little fish, lives in small pools of water. When their living place dries up, they live on the land, said Scott Taylor, a researcher in Florida.
The fish can grow as large as three inches. They group together and breathe air through their skin before they can find water again.
The new scientific discovery came during a trip.
“We were travelling for fun. and one day I kicked over a log (圆木) and the fish came out.” Taylor told reporters by telephone. He said he would make his study on the fish known to the public in an American magazine early next year.
In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.
Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at a time, while lungfish (肺鱼) found in Australia, Africa and South America can live out of water, but only in a not active (活波的) way. But no other known fish can be out of water as long as the Mangrove Rivulets and keep active, according to Patricia Wright, a biologist at a Canadian University.
More studies of the fish may tell how animals changed over time.

I had just gone to bed after a very hard day when the phone rang. It was an eccentric(怪僻的)farmer. I had never met him before although, I had often heard people talk about him. He sounded quite nervous and he had been talking for a minute or so before I understood anything. Even then all I could make out was that someone called Milly had had a very bad accident. I had not the slightest idea who she was but I obviously had to go.
It had been snowing heavily that day and I did not know the way. I had been driving for at least an hour when I finally found his place. He was standing there, waiting for me. It seemed Milly had died. “She meant more to me than anyone…even my wife!” he said. I could see that he had been crying. I thought something terrible had taken place, a possible scandal(丑闻). I was even more shocked when he told me he had put her in the barn(厩). “I wouldn't leave her out in the cold!” he said.
Milly had clearly been a secret lover of his. I was about to tell him he could not expect me to cover anything up when he opened the barn door.

In the past, man did not have to think about the protection of the environment. There were few people on the earth, and natural resources(资源) seemed to be unlimited(无限的) .
Today things are different, the world has become too crowded. We are using up our natural resources too quickly and at the same time we are polluting our environment with dangerous chemicals (化学制品). If we continue to do this, human life on the ①_______ will ②_______ survive.
Everyone realizes today that if too many fish are taken from rivers and the sea, there will soon be none left. Yet, with modern fishing methods(方法) , more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on the earth. Yet we continue to use bigger and more powerful machines to cut down more and more trees.
We realize that if rivers are polluted with waste products from factories, fish will die. However, in most countries wastes are still put into rivers or the sea, and there are few laws to prevent this. Also, weknow that if the population of the world is becoming larger and larger, in a few years there will not be enough food. What can we do to solve these problems?
If we eat more vegetables and less meat, there will be more food available for everyone.
③Our natural resources will last longer if we learn to recycle(循环再用)them. The world population will not rise so quickly if people use modern methods of birth control.
Finally, if we educate people to think about the problems, we shall have a better and cleaner planet in the future. In a word, it is very important to protect our environment.

Dear Victor,
I have received your loving letter from school and I am glad to know that you are becoming responsible(有责任的) enough to decide on your career(职业).
You are now in the final year of high school and are going to start further education in college. You know that we belong to different times, and my social life is different from yours. However, all I can say as advice is that you must choose a career wisely. The first consideration is your interest. You can only succeed and feel happy when you do something you enjoy. You must get a job which not only provides you with something useful, but also you are pleased with. Then, you must read a lot in the field(领域) you are aiming at. Also, you should get to know the men and women who work in that field. When mind and heart work together, success is inevitable.
No career is more or less important. I think your interest may be in the field of making TV programs. Your good communication skills, your taking an active part in school plays and the prizes you have won in speech competitions all lead you to that direction. So a career in Mass Communication and TV film production will bring luck to you. If you succeed in that field, you will become famous and rich.
Think a thousand times before making any final decision about your career. After all, we want you to be a man of success.
We all know that you are old enough to think for yourself.
With all the best wishes! Your loving father

I was offered several part-time jobs at university. Finally I decided to give one of them a go. Now I work in a dining hall on campus(校园). My main duties are to serve food and wash dishes.
I discovered I would have to stand still for at least three hours at a time and was afraid it was not going to be as much fun as I had thought. Smiling all the time and remembering all the strange food names have been a challenge(挑战), too.
I have had really funny experiences. One of the sauces is called "marinara" which is a kind of tomato-based sauce like salsa（辣茄酱）． Before I knew what it was, someone asked me to give him the sauce, and I replied: "What? The marijuana(大麻) sauce?" He was astonished. Marijuana is an illegal(非法的 ) drug and has nothing to do with sauce. It was quite embarrassing(使人尴尬的)! I have never forgotten the word "marinara" since then.
I also had to make a wrap（卷饼） for the first time. I had tasted Mexican wraps many times in China, but making one was a different matter. I could feel my face was burning with sweat and embarrassment as I broke the thin wraps again and again while people were waiting impatiently. Mexican wraps taste great when they're soft, but I do wish they could be made thicker and harder so they wouldn't break so easily.
My favorite part of the job is working in the kitchen. I hold the water cannon(水枪) like a policeman about to fight with "criminals” ----the dirty dishes. It's quite exciting to feel the water rushing out of the pipe. I usually get thoroughly(彻底地) soaked, but it feels good, a bit like taking a shower. Sometimes our boss allows us to play music to cheer us up. I often hum along to the music while washing dishes.
This is my first experience of being a student worker. It is hard work, but it's turning out to be quite fun.

The Sydney Opera House is a very famous building in the world. It has become Sydney's best-known landmark and international symbol. The Opera House with a "sailing roof" was designed by a famous Danish(丹麦建筑师), Utzon. The base for the building was started in 1959, years before the designs were finished. Utzon spent four years designing the Opera House. In 1962, the designs were finalized（定稿）and the construction began. In 1967, they started the decoration inside. It took 14 years in total to build the Opera House. Queen Elizabeth II officially opened it on October 20th, 1973.
