Challenges of life are of great importance in our grow. They remind me of my days in senior high school which I joined in the military training after I entered senior high school. It was the first time that I have lived away from my home, so I found it difficult to fit. And the training officer was strict with me. I once thought I couldn't stick to the end. But anyway, I was succeeded. The trials made it much easy for me to adapt to life, but I think the difficulty I came across have now become a precious memory in my life.
In short, learning to regard the challenges of life as the stepping stone to future success and make the best of them.

Culture means any human behavior that is learned in human society. All of the meaningful parts of a culture are passed on to different generations through tradition or social learning. 1.Culture exists in agricultural as well as industrialized societies.
Culture is necessary for the survival and existence of human beings as human beings. Practically everything humans know, think, value, feel, and do is learned through taking part in a sociocultural system. 2. Here is one of the cases of children growing up apart from human society. In the province of Midnapore in India, the director of a children’s home was told by local villagers that there were “ghosts” in the forest. Upon looking into the case, the director found that two children, one about eight years old and the other about six years old, appeared to have been living with a group of wolves in the forest. 3. In his diary, the director describes his first view of Kamala (as the older child was named) and Amala (the name given to the younger child):
Kamala was a terrible-looking being, the head, a big ball of something covering the shoulders. 4.Their eyes were bright and sharp, unlike human eyes. They were very fond of raw meat and raw milk. Gradually, as they got stronger, they began going on all fours, and afterwards began to run on all fours, just like squirrels.
Children learn human language in the same way they learn other kinds of human behavior--by taking part in a cultural community. 5..
A. From this viewpoint, all human groups have a culture.
B. These children were the ghosts described by the local people.
C. This statement is well supported by some well-written cases.
D. Human beings can only develop human abilities by the local people.
E. Culture refers only to the high art and classical music of a particular society.
F. Close at its heels there came another terrible creature exactly like the first, but smaller in size.
G. They learn a certain human languages as well as certain kinds of human behavior through their membership in a certain cultural community.
