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, then 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.

When I was twenty-seven years old, I was a clerk in San Francisco. I was alone in the world, and had nothing to depend on but my brain and a clean reputation.

My time was my own after the afternoon board on Saturdays, and I would spend the time on a little sailboat on the bay. One day I sailed too far, and was carried out to sea. At nightfall, when hope was almost lost, I was picked up by a small boat, which headed for London. It was a long and stormy journey, and they made me earn my passage as a common sailor. When I stepped on land in London, my clothes were ragged and shabby, and I only had a dollar in my pocket. This money fed and sheltered me for 24 hours. During the next 24 hours I went without food and shelter.

About ten o’clock on the following morning, tired and hungry, I was walking along Portland Place, when a passing child, threw a big pear into the rubbish can. I stopped, of course, and stared at that muddy treasure. My mouth watered for it. My whole body begged for it. But every time I made a move to get it, some passing eyes noticed my purpose, and of course I straightened up, looked calm, and pretended that I hadn’t been thinking about the pear at all. The same thing kept happening and happening, and I couldn’t get the pear. I was just getting desperate enough to face all the shame and get the pear, when a window behind me was opened, and a gentleman said, “Step in here, please.”

A. had a great reputation for his good work

B. worked as a common sailor during the journey

C. was carried out to sea on purpose by a small boat

D. had nothing left in his pocket after landing in London

2. Why didn’t the man pick up the pear at once?

A. Because a gentleman stopped him and let him in.

B. Because he was not so hungry that he could wait.

C. Because the child was watching the pear.

D. Because he didn’t want others to take him as a beggar.

3. The underlined word “desperate” means “_______”.

A. driven by great need or pain to do something

B. being afraid of doing something for a certain reason

C. enjoying, showing, or marked by pleasure or joy

D. feeling sorry or sad about something
