The discovery of a dwarfed (矮个的)”human being” who lived in Flores .Indonesia, up to 18,000 years ago is changing the way we think about the human family .This “Flores Human”was three foot tall and her brain was smaller than that of the average chimp (黑猩猩),yet she and her relatives apparently lived fully human lives.They seem to have made tools ,worked together to find food and cook it,and perhaps even buried their dead with ceremony.
It was a major surprise to find tools associated with the new human family member .The tools are like those formerly seen only with European fossils (化石)from our own species;Homo sapiens (智人)；and the oldest of them were made 94,000 years ago .Homo sapiens is thought to have arrived in the island about 40,000 years ago ,much too late to be responsible for the tools .If this tiny human made the tools ,them the inside structure (结构)of its brain must have been more like our own than a chimp’s ,despite being just a third the size of ours.
This “new human” was suspected to be a dwarfed branch of Homo erectus (直立人).When creatures are separated in regions with rare resources but few enemies,being big is a disadvantage, and evolution tends to shrink them, a process known as island dwarfing.Could natural selection make a human smaller while keeping — even improving — mental ability ?Quite possibly, believes Christopher Wills of the University of California.
Has the “Flores Human” even shown the ability of language? “I find it difficult to imagine that people could make tools，use fire ,and kill large animals without fairly advanced communication.” Wills says .Did “Flores Human” possess the basic components of human culture — such as the burying of the dead with ceremony ? Emiliano Bruner of the Italian Institute points out that Indonesia’s hot, wet environment is bad for fossilization.It is reasonable to assume , he says ,that the 18,000-year-old bones of the most complete Flores woman were well-preserved because she was buried with special care.

Directions: Read the following passage. Answer the questions according to the information given in the passage and the required words limit. Write your answers on your answer sheet.
Fast food and too much TV time should not take all the blame for the weight problems. A group of researchers say that a number of aspects of modern living from lack of sleep to environmental chemicals and to living with air conditioning ——may be closely related to the weight problems of many people.
Lack of sleep is one of factors. Research in animals and humans suggest that a lack of sleep over a long time can increase appetite. Studies also show that many adults and children are sleeping less than they used to. In recent decades, adults have gone from sleeping for all average of nine hours to about seven hours.
There is also evidence that industrial chemicals may increase body fat. These chemicals, which are used in products, change hormonal activity when they get into the body. Studies suggest that people have been getting more and more of these chemicals through the food chain in recent decades.
Another factor that may be making people overweight is air conditioning . The body burns calories when forced to eat less in hot and wet weather, but air conditioning makes it unnecessary for the body to make any adjustment.
Researchers also list other possible risk factors for overweight , including more older mothers, whose children may become overweight more easily; a number of medicines which can lead to weight gain ; and fewer people who smoke, since people often gain weight when they stop smoking because nicotine can make people eat less.
No one is suggesting that people should stop working and sleep more, or keep smoking. When it comes to any person's weight, what really matters is how much they eat and how much of the food they use every day. That means diet and exercise are still the key.
