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”
B. the language used by “Flores Human”
C. the evolution of “Flores Human”
D. the major surprising findings about “Flores Human”
4.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

Recently there was a major discovery in the scientific research — the mapping of all DNA in a human gene(基因) is complete.Couple of years ago, this seems an impossible task for scientist to accomplish.All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away.Human cloning has always been a topic of argument, in terms of morality(道德) or religion.
Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning.If the clone was free of genetic limitations, then the other clone would be as well.The latter could be inserted in the woman and allowed to ripen to term.Moreover, cloning would enable women, who can’t get pregnant, to have children of their own.
Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs.This surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single (or more) organ(s).It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.
Arguments against cloning are also on a perfectly practical side.Primarily, I believe that cloning would step in the normal “cycle” of life.There would be a large number of same genes, which reduce the chances of improvement, and, in turn, development — the fundamental reason how living things naturally adapt to the ever-changing environment.Life processes failing to do so might result in untimely disappearance.Furthermore, cloning would make the uniqueness that each one of us possesses disappear, thus leading to creation of genetically engineered groups of people for specific purposes, and chances are that those individuals would be regarded as “objects” rather than people in the society.
Scientists haven’t 100% guaranteed that the first cloned humans will be normal.Thus, this could result in introduction of additional limitations in the human “gene-pool”.
Regarding such arguable topics in “black or white” approach seems very innocent to me personally.We should rather try to look at all “shades” of it.I believe that cloning is only legal if its purpose is for cloning organs; not humans.Then we could regard this as for “saving life” instead of “creating life”.I believe cloning humans is morally and socially unacceptable.
1.Which of the following is true according to the passage?
A.Genetic limitations will be beneficial for some women.
B.A large number of genes will prevent us from developing.
C.First cloned humans might be normal according to scientists.
D.Forbidding cloning might limit the freedom of scientists.

Yet, our cells simply cannot continue to reproduce ___. They wear out, and as a result, we get old and ___ die.

People are living longer because more people ___ childhood. Before modern medicine changed the laws of nature, many children died of common childhood ___. Now that the chances of dying ____ are much lower, the chances of living long are much higher due to better diets and health care.
On the whole, our population is getting older. The ____ in our population will have lasting effects on our social development and our way of life. Some people fear such changes will be for the worse, while some see ____, not disaster. Today, many men and women in their "golden years" are healthy, still active, and young in ____ if not in age.
