Botany, the study of plants, occupies a peculiar position in the history of human knowledg
e. For not many thousands of years it was the one field of awareness about which humans had anything more than the vaguest of insights(了解). It is impossible to know today just what our Stone Age ancestors knew about plants. But from what we can observe of pre-industrial societies that still exist, a detailed learning of plants and their properties must be extremely ancient. This is logical. Plants are the basis of the food pyramid for all living things, even for other plants. They have always been enormously important to the welfare of peoples, not only for food, but also for clothing, weapons, tools, dyes, medicines, shelter, and a great many other purposes. Tribes living today in the jungles of the Amazon recognize literally hundreds of plants and know many properties of each. To them botany, as such, has no name and is probab-ly not even recognized as a special branch of "knowledge" at all.

Unfortunately, the more industrialized we become, the farther away we move from direct contact with plants, and the less distinct our knowledge of botany grows. Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose, an apple, or an orchid. When our Neolithic ancestors, living in the Middle East about 10,000 years age, discovered that certain grasses could be harvested and their seeds planted for richer yields the next season, the first great step in a new association of plants and humans was taken. Grains were discovered and from them flowed the marvel of agriculture: cultivated crops. From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varie-ties that grew wild and the accumulated knowledge of tens of thousands of years of experience and intimacy with plants in the wild would begin to fade away.

It is assumed in the passage that early humans ______.

A.probably had extensive knowledge of plants

B.thought there was no need to cultivate crops

C.did not enjoy the study of botany

D.placed great importance on the ownership of property

Fishing adds only about 1 percent to the global economy, but on a regional basis it can co
ntribute enormously to human survival. Marine fisheries contribute more to the world's supply of protein than beef, poultry or any other animal source.

Fishing typically does not require land ownership, and because it remains, in general, open to all, it is often the employer of last resort in the developing world--an occupation when there are no other options. Worldwide, about 200 million people depend on fishing for their livelihoods. Within Southeast Asia alone, more than five million people fish full-time. In northern Chile ,40 percent of the population lives off the ocean. In Newfoundland, most employment came from fishing or servicing that industry--until the collapse of the cod fisheries in the early 1990s left tens of thousands of people out of work.

Although debates over the conservation of natural resources are often cast as a conflict between jobs and the environment, the restoration of fish populations would in fact boost employment. Michael P. Sissenwine and Andrew A. Rosenberg of the U. S. National Marine Fisheries Service have estimated that if depleted species were allowed to rebuild to their long-term potential, their sustainable use would add about $ 8 billion to the U. S. gross domestic product--and provide some 300, 000 jobs. If fish populations were restored and properly managed, about 20 million metric tons could be added to the world's annual catch. But restoration of ecological balance ,fiscal profitability, and economic security will require a substantial reduction in the capacity of the commercial fishing industry so that wild population can recover.

The necessary reductions in fishing power need not come at the expense of jobs. Governments could increase employment and reduce the pressure on fish populations by directing subsidies away from highly mechanized ships. For each $1 million of investment, industrial-scale fishing operations require only one to five people ,whereas small-scale fisheries would employ between 60 and 3000. Industrial fishing itself threatens tens of millions of fishermen working on a small scale by depleting the fish on which they depend for subsistence.

The animal source which supplies the most protein for human being is ______.

A.beef

B.fish

C.pork

D.chicken

Genes that control factors such as size, color and shape determine the differences in fruit. And now that scientists have discovered how to detect different genes, farmers can hand over a young and tender branch to have its genes checked prior to planting. It works the same way as a detective checking fingerprints. Once farmers know which trees are good and which are bad, they can discard the bad ones. Farmers can even create new varieties according to their individual tastes.In the past three years, tens of thousands of tests were carded out to determine the genetic (基因的) features 0f fruit. Zhang, a Chinese scientist, showed a photo of a DNA-test and pointed to the shining lines on it, saying thatthe lines were genetic signs that tell us what a tree's fruit will be like. For example, the ordinary pear tree bears fruit after four years. But now it only takes a month to test the DNA from a young leaf and a farmer will know everything about its fruit. By mixing different types of trees with suitable genes, farmers can create whatever fruit trees they want.

21.Detecting different genes in plants is like().

A.the examination of human finger-prints

B. the development of new varieties of fruit

C.the checking of young a nd tender branches

D.the distinction between bad trees a nd good ones

23.We learn from the first paragaph that the study of genes.()

A. has greatly affected fruit output

B. has been a popular planting procedure

根据以下资料,回答{TSE}题。 Up until a few decades ago, our visions of the future were larg
ely - though by no means uniformly - glowingly positive.Science and technology would cure all the ills of humanity, leading to lives of fulfillment and opportunity for all. Now utopia has grown unfashionable, as we have gained a deeper appreciation of the range of threats facing us, from asteroid strike to epidemic flu and to climate change.You might even be tempted to assume that humanity has little future to look forward to. But such gloominess is misplaced.The fossil record shows that many species have endured for millions of years - so why shouldn't we? Take a broader look at our species' place in the universe, and it becomes clear that we have an excellent chance of surviving for tens, if not hundreds, of thousands of years .Look up Homo sapiens in the "Red List" of threatened species of the International Union for the Conversation of Nature (IUCN) ,and you will read: "Listed as Least Concern as the species is very widely distributed, adaptable, currently increasing, and there are no major threats resulting in an overall population decline." So what does our deep future hold? A growing number of researchers and organisations are now thinking seriously about that question.For example, the Long Now Foundation has its flagship project a medical clock that is designed to still be marking time thousands of years hence . Perhaps willfully , it may be easier to think about such lengthy timescales than about themore immediate future.The potential evolution of today's technology, and its social consequences, is dazzlingly complicated, and it's perhaps best left to science fiction writers and futurologists to explore the many possibilities we can envisage.That's one reason why we have launched Arc, a new publication dedicated to the near future. But take a longer view and there is a surprising amount that we can say with considerable assurance.As so often, the past holds the key to the future: we have now identified enough of the long-term patterns shaping the history of the planet, and our species, to make evidence-based forecasts about the situations in which our descendants will find themselves. This long perspective makes the pessimistic view of our prospects seem more likely to be a passing fad.To be sure, the future is not all rosy.But we are now knowledgeable enough to reduce many of the risks that threatened the existence of earlier humans, and to improve the lot of those to come. {TS}Our vision of the future used to be inspired by

A. our desire for lives of fulfillment

B. our faith in science and technology

C. our awareness of potential risks

D. our belief in equal opportunity

I told the German official at the time that I was sure the【B11】would fail.

The German Green Card was misnamed, I argued,【B14】it never, under any circumstances, translated into German Citizenship. The U.

The official【B16】my objection, saying that there was no way Germany was going to offer these people citizenship. "Vie need young tech workers," he said. "That's what this program is all【B17】"So Germany was asking bright young【B18】to leave their country, culture and families, move thousands of miles away, learn a new language and work in a strange land—but without any【B19】of ever being part of their new home.
