Unlike many of my classmates, my idol (偶像) is not a film star or a famous writer. Neither is he a world leader, nor an important person from . My idol is my dad.
Most people believe that a man should go out and work. However, when I was a baby, I was very ill and needed attention all the time. Since my mother and father both worked, and my grandparents lived very loved her job, so he stopped working to stay at home and look after me.
Many men in this would want their wives to stay with the child, but my dad always thinks about others before himself. My dad took a job and worked at night. He chose the job so that he would only be out of the house when I was sleeping.
Ever since then, my dad has helped and me in everything I do. The most important thing he taught me was never to . I remember when I was learning to ride a bike. My dad would run behind me for hours. He held the back of the bicycle so that I would not fall. I felt so because I knew (转载自：www.dXf5.cOm 东星资源网:上海松江中考状元)he was near. I did not when he stopped holding me. Soon, I was riding by myself.
My family is not rich, and we do not own a big house or an expensive car. My dad is my idol because he has shown me that the most important things in life are family and love.

A 12-man Chinese team landed on the Antarctic icecap peak(南极冰盖最高点) on January
18. They are the first people to the peak of Dome A (海穹A). It is 4,039 meters above sea level.
The team built a there to study the changes of the weather, get ice samples (标本) from 150 meters to 200 meters below, and do other 100-meter long ice samples from a place about 300 meters under the icecap peak.
It is the first time that people have been able to get samples from the icecap peak in
Antarctica and it is very important for people to study the weather changes and environmental changes in this area.
The Chinese scientists have built a weather study system at the peak. The system can send out about temperature, how strong the wind is, and many about the weather.
The Antarctic icecap makes up 70% of the earth’s freshwater. By studying Dome A, scientists can get the lowest temperature of the earth and information about the world’s weather changes. We get this information from other places on the earth because Dome A is the best place for this kind of studies. So it is very important to land on the peak of Dome A.

Zoos are places where different kinds of animals are kept and shown for the public. At most
modern zoos people can see, smell and hear animals in their natural way.
Some zoos even have “friendship farms" where people can touch some
of the animals. Here are some why people need zoos.
Firstly, zoos help people know more about animals and their
where it comes from and how it lives. Special teachers at the zoo help
children understand more about the animals. Trained guides show
visitors around the zoo.
Secondly, zoos are working hard to find out more about animals. New knowledge leads to better ways of looking after animals in the zoo and understanding of the same animals
in the wild.
Thirdly, zoos play a part in protecting animals and stopping them from together with each other to help the animals in danger. For example, gorillas (大猩猩) from
Taronga Zoo were sent to live with gorillas at the Melbourne Zoo in the hope that they would give birth to babies gorillas can be kept in this way.
Finally, zoos give people a lot of fun. People enjoy getting close to animals having to cross the plains (平原) of Africa or climb the mountains of China. In the past, animal shows
were common in zoos. Visitors were when they saw monkeys in human clothes, and they even took rides on elephants or horses. However, today people prefer to see animals in a more natural way.
So a modern zoo is a place where animals are well taken care of.
