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, 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.

1.According to the passage, “Flores Human” __________.

A. lived a partly human life

B. was a branch of Homo sapiens

C. used tools before Homo sapiens arrived

D. had a brain as large as a common chimp’s

2.The underlined part “this tiny human” in Paragraph 2 refers to __________.

A. a chip       B. Flores Human     C. Homo sapiens     D. Homo erectus

3.This passage mainly talks about __________.

A. the tools made by “Flores Human”

读下面的短文,把方框内的数量词填入短文内

  Pinatubo awoke on   1  .Hot ash and gas flowed down the hillside and ash clouds rose   2   into the atmosphere.

  On the volcano’s slopes, seven cubic kilometers of pulverized(成粉末状)rock now lay in drifts(漂流)  3   feet thick, totally reshaping the landscape.

  One of the first dangers is falling debris(残骸)collecting on houses and causing roofs to collapse(塌陷).In fact that was the main killer for this eruption.The eruption had come with the annual Typhoons that regularly swept the Islands.Heavy rainfall hit the hot and loosely packed volcanic debris.It was to be the start of a terror(恐怖)that would kill the people here long after the eruption stopped.

  Imagine a truck delivering wet concrete(混凝土).But expand that material to   4   cubic meters of debris-all moving at the same time-and you have a Lahar(火山泥石流).

  40 kilometers downstream from Mount Pinetubo is the town of Bacalor.Years after the eruption stopped, this town still suffers the onslaught(冲击)of Lahars.Most of its population of   5   have departed to resettlement camps.

  About   6   of the population of Bacalor never left.They had been warned many times but the people remained.They seemed to be there forever.

  Every year when the rains come new Lahars swamp(淹没)the town raising the land ever higher.Still people rebuild their homes.

  Some of them have houses twice or even three times.And some people gave up, and others raised it   7  

  Bacalor was originally a township of twenty-one large villages.Today only   8   remain.

  The broken remains of Mount Pinetubo are silent now.But its volcanic ash lay heavy on its slopes.Just   9   of heavy rain, can produce a Lahar.It is not unusual to have eighteen Typhoons a year.So Philippine scientists constantly monitor(检测)the weather on the mountain’s slopes.Since the eruption,   10   Lahars have occurred, and all resulted from Typhoon rain.To reduce its damage, a huge system has now been constructed.
