　　On the back streets of cities and villages in China, doorways are a unique sight for a visitor like me. The doorways that interested me most were in the small lanes, called“hutongs”.

　　In other cities I saw the doorways were different from those in Beijing. In the country villages, farmers have words expressing good luck written on red paper and placed on both sides of their front doorways. This creates a festive atmosphere with a uniquely Chinese flavor. It was the harvest season when I visited. Farmers put wheat straw on the street outside their houses to dry. The straw will later be used to make artwork to sell in the market. The wheat straw leaning on the wall outside the old farmhouses makes a pretty picture of country life. On these back streets, I see people enjoy a peaceful and relaxed life style, different from the fast paced life in the city. I saw some older people playing chess and cards. I saw some tend their birds or other pets and some were just chatting amiably.

　　Most of the houses in back streets are for residents, but some are for businesses or government offices, even restaurants. I cannot say that the people still living there are the ones who are unable to move to a new place. Perhaps it is a life style they prefer, for some residents there drive expensive cars and dress fashionablely.

　　Whith the rapid progress of city development, more people will move into new homes and these hutongs will not be seen in a few years. It is true that in recent years, many houses on these back streets have been pulled down and replaced by modem buildings. It is not easy to renovate the old houses, so it is natural that they are torn down and replaced. In fact in some cities I see that everyone lives in new apartment buildings in residential areas. Hutongs are quickly becoming a part of the past.

Recently, some concerns have been raised about the health of the world's banana plants. Many media reports have said that bananas may completely disappear in the coming ten years.
Bananas are one of the world's most important food crops. They are also the fourth most valuable export. Bananas do not grow from seeds. Instead, they grow from existing plants. Bananas are threatened by disease because all the plants on a farm are copies of each other. They all share the same genetic weaknesses.
For example, the Cavendish banana is most popular in American markets. It is an important export crop. However, some kinds of fungus (真菌) organisms easily infect the Cavendish. Black Sigatoka disease affects the leaves of Cavendish banana plants. The disease is controlled on large farms by putting chemicals on the plant's leaves. Farmers put anti-fungal chemicals on their crops up to once a week.
Another fungal disease is more serious. Panama disease attacks the roots of the banana plant. There is no chemical treatment for this disease. Infected plants must be destroyed. Panama disease has affected crops in Southeast Asia, Australia and South Africa. There is concern that it may spread to bananas grown in the Americas. This could threaten an important export product for Central and South America.
The International Network for the Improvement of Banana and Plantain, whose headquarter lies in France, supports research on bananas. The group says that more research must be done to develop improved kinds of bananas.
The group says that fungal diseases mainly affect only one kind of banana. In fact, there are five-hundred different kinds of bananas. The United Nations Food and Agriculture Organization says the Cavendish banana represents only ten percent of world production.
The UN agency says farmers should grow different kinds of bananas. This protects against diseases that affect only one kind. Experts warn that disease may cause the Cavendish banana to disappear. This has already happened to one popular banana because of its genetic weakness against disease. (words: 335)
