According to the passage, what was the first great step toward the practice of agriculture? A. The invention of agriculture tools and machines. B. The development of a system of names for plants. C. The discovery of grasses that could be harvested and replanted. 答案 67.A 68.D 69.D 70.C Passage 12 (江苏省启东中学2009届高三最后一卷B篇) When a handheld video game runs out of power, all you have to do is plug it in and charge it up. Within a few years, some of you might do the same thing with mom’s car. Automobile companies are developing vehicles that will plug into electric sockets , just like many laptops, digital cameras, cell phones and small video game players do. Called “plug-in hybrids , these cars will get most of their power from electricity. Their drivers will rarely have to stop at gas stations. The technology is more than just cool. In our automobile-filled world, plug-in vehicles could reduce the amount of gasoline we use. That gas is made from crude oil, which has been kept rising in cost. Plus, driving around in these hybrids may even help the environment. Gas-burning cars produce a lot of carbon dioxide, a type of greenhouse gas. These gases stay in the atmosphere, where they trap heat and cause global warming. The first company-produced plug-in hybrids could hit the roads by 20l0. But engineers still have a lot of work to do to make the technology practical and inexpensive. Batteries are the biggest challenge. In the plug-in-hybrid world, Li-ion batteries are getting the most attention. These batteries can store a large amount of energy in a small package, and they last a relatively long time between charges. Li-ion batteries are standard in laptops, cell phones, heart devices and similar portable devices. But because cars are so big and heavy, it would still require a suitcase-sized Li-ion battery to power about l2km of driving. What’s more, the batteries are extremely expensive. “A car filled with batteries could go a long distance, says Ted Bohn, an electrical engineer in Chicago. “But it couldn’t haul any people, and it would cost $l00,000. So researchers need to figure out how to make batteries smaller and cheaper, among other questions. “The answers don’t exist yet, Bohn says. “As a kid I thought someone someplace knows the answer to everything. All of these questions haven’t been decided. That’s what engineering is about - making a guess, running tests and fine-tuning results. 查看更多

  Botany, the study of plants, plays a strange role in the history of human knowledge.For many thousands of years it was one field about which humans had little knowledge.It is impossible to know today just what our Stone Age Ancestors knew about plants, but from what we can observe of preindustrial societies that still exists, a detailed learning of plants and their properties(特征)must be very ancient.This is reasonable.Plants are the basis of the food pyramid for all living things, even for other plants.They have always been greatly important to the good of peoples, not only for food, but also for clothing, weapons, tools, medicines, housing, and a great many other purposes.Tribes(部落)living today in the woods of the Amazon recognize hundreds of plants and know many properties of each.To them botany, as such, has no name and is probably not even recognized as a special branch of knowledge at all.

  Unfortunately, the more industrialized we become the farther away we move from direct relation with plants, and the less clear our knowledge of botany grows.Yet everyone comes unconsciously on a surprising amount of botanical knowledge, and few people will fail to recognize a rose or an apple.When our New Stone Age ancestors, living in the Middle East about 10 000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer production the next season, the first great step in a new connection of plants and humans was taken.Grains were discovered and from them flowed the marvel of agriculture:planted 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 varieties that grew wild and the collected knowledge of tens of thousands of years of experience and close relations with plants in the wild would begin to disappear.

A.

They probably had wide knowledge of plants.

B.

They clearly divided knowledge into separate fields

C.

They did not enjoy the study of botany.

Botany is not recognized as a special branch of science.
