     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.   

67. 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

68. The underlined part "this tiny human" in Paragraph 2 refers to

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

69. This passage mainly talks about______.

    A. the tools made by "Flores Human"   B. the language used by "Flores Human"

    C. the evolution of "Flores Human"

    D. the major surprising findings about "Flores Human"

70. According to the passage, it is believed that "Flores Human"______.

    A. was dwarfed by its enemies         B. could use language

    C. left a lot of fossils in the hot and wet environment

    D. reached Flores 40,000 years ago

67. C  

解析:此题的依据在第二段中,比较隐蔽,但可以用排除法,A,B,D明显与文章矛盾

68.B  

解析:本文就是围绕Flores Human展开的,A,C,D都只是说明一些情况。根据上下问可知this tiny human指的是B.

69. D

解析: 把A,B,C都概括了。A,B,C都比较片面

    70

解析: B,根据最后一段可知。 A,C,D均与文章矛盾

In 1752, three years after two Scotsmen, Alexander Wilson and Thomas Melville, fastened thermometers to kites to record the temperature of clouds, Benjamin Franklin made his famous experiment with a kite, a string, and a key.Franklin hoped to show that nature’s tremendous displays of electricity in lightning were the same thing as the feeble electric sparks scientists of the day were producing in their laboratories.He built a square kite to which he attached an iron wire.He flew the kite with a hemp string(麻线), and near the base of the string he tied a large brass key.The kite rose into a dark thundercloud, where the iron wire picked up electrical charges.Franklin noticed that the strands of the string(绳串)were beginning to stand up with electricity.As rain wet the string, it conducted more electricity.Standing in the shelter of a shed, Franklin cautiously reached out his finger to touch the brass key.A series of sparks jumped from the key to his finger.He thus proved that lightning and electricity are the same.We now know that this experiment was a dangerous one, for Franklin might have been killed by a bolt of lighting.
