The discovery of a dwarfed (矮個(gè)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 (結(jié)構(gòu))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 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 hot and wet enviroment D.reached Flores 40,000 years ago

Human remains of ancient settlements will be reburied and lost to science under a law that threatens research into the history of humans in Britain, a group of leading archeologists (考古學(xué)家) says. In a letter addressed to the justice secretary, Ken Clarke, 40 archaeologists write of their “deep and widespread concern” about the issue. It centers on the law introduced by the Ministry of Justice in 2008 which requires all human remains unearthed in England and Wales to be reburied within two years, regardless of their age. The decision means scientists have too little time to study bones and other human remains of national and cultural significance.
“Your current requirement that all archaeologically unearthed human remains should be reburied, whether after a standard period of two years or a further special extension, is contrary to basic principles of archaeological and scientific research and of museum practice,” they write.
The law applies to any pieces of bone uncovered at around 400 dig sites, including the remains of 60 or so bodies found at Stonehenge in 2008 that date back to 3,000 BC. Archaeologists have been granted a temporary extension to give them more time, but eventuallly the bones will have to be returned to the ground.
The arrangements may result in the waste of future discoveries at sites such as Happisburgh in Norfolk, where digging is continuing after the discovery of stone tools made by early humans 950,000 years ago. If human remains were found at Happisburgh, they would be the oldest in northern Europe and the first indication of what this species was. Under the current practice of the law those remains would have to be reburied and effectively destroyed.
Before 2008, guidelines allowed for the proper preservation and study of bones of sufficient age and historical interest, while the Burial Act 1857 applied to more recent remains. The Ministry of Justice assured archaeologists two years ago that the law was temporary, but has so far failed to revise it.
Mike Parker Pearson, an archaeologist at Sheffield University, said: “Archaeologists have been extremely patient because we were led to believe the ministry was sorting out this problem, but we feel that we cannot wait any longer.”
The ministry has no guidelines on where or how remains should be reburied, or on what records should be kept.
【小題1】According to the passage, scientists are unhappy with the law mainly because ______.
| A．it is only a temporary measure on the human remains |
| B．it is unreasonable and thus destructive to scientific research |
| C．it was introduced by the government without their knowledge |
| D．it is vague about where and how to rebury human remains |
| A．Temporary extension of two years will guarantee scientists enough time. |
| B．Human remains of the oldest species were dug out at Happisburgh. |
| C．Human remains will have to be reburied despite the extension of time. |
| D．Scientists have been warned that the law can hardly be changed. |
| A．The Ministry of Justice did not intend it to protect human remains. |
| B．The Burial Act 1857 only applied to remains uncovered before 1857. |
| C．The law on human remains hasn’t changed in recent decades. |
| D．The Ministry of Justice has not done enough about the law. |
| A．New discoveries should be reburied, the government demands. |
| B．Research time should be extended, scientists require. |
| C．Law on human remains needs thorough discussion, authorities say. |
| D．Law could bury ancient secrets for ever, archeologists warn. |

B
Can you imagine traveling to work in a one-man submarine? Some scientists believe that some day one-man submarines will be as numerous (許多) as automobiles are today. A famous French driver says, “One day soon, men will walk on the ocean floor as they do on the street!” Perhaps during your lifetime people will travel, work, and live in the sea.
If human beings want to live in the ocean, many human problems will need to be studied first. Some of these problems, similar to those of living in outer space, are pressure, lack of oxygen and weightlessness. Many questions remain unanswered．For example, can our blood adjust itself to underwater surroundings? What will happen to our muscle if we live in the water very long? Scientists are searching for answers.
Perhaps in the future man will live in the sea, away from the crowded and noisy cities on land．The sea has plenty of space, not only for floating communities (團(tuán)體) and parks, but also for storing supplies and for underwater travel.
Some scientists believe that ocean living will benefit man in more than physical ways. In the freedom and beauty of the deep sea, man may find new sources of joy.
60．According to the passage, which of the following is true?
A．Man will live in the sea just like living on the earth in time.

As I understand, if scientists produced a human clone, there would be a great risk of it having a disease. Nobody seems to understand the ageing process of a clone. It would be terrible if a baby was the age of its parent at 31 . Its cells would grow old fast and it would die young. 32 until the technique is perfectly safe, it should be 33 .
I'd love to have a clone of 34 . I often wish I had a twin sister, someone who 35 me in everything. So why not a clone? Well, the idea 36 be fun but I'm not sure if it would be 37 . I think we would be playing with fire if we let scientists go ahead with 38 cloning. There are so many 39
involved that all research in this area should be strictly controlled.
There are so many arguments 40 cloning that it is difficult to get anyone to consider the possible benefits. I am 41 that it is a technique which could be beneficial. The most obvious use would be for childless 42 . They would be able to have babies with their own genetic material. I don't see what's wrong with that.
Imagine a child 43 up knowing that his or her mother is really a sister or a brother. The emotional 44 on the child would be 45 . Or a child who was cloned from a dead brother or sister. What kind of emotional pressure would they feel, knowing they were made as a replacement for another? The whole idea
46 me!
It's all very good to ban human cloning but scientists should be allowed to 47
research. If they don't, we may 48 important benefits for our society, such as producing body organs. A clone is an 49 copy of a person with the same gene. Therefore, it is the 50 donor for an organ(器官) transplant.
