The Erie Canal was the first important national waterway built in the US. It crossed New York from Buffalo on Lake Erie Troy to Albany on the Hudson River. It joined the Great Lakes with the Atlantic Ocean. The canal served as a route over which industrial goods could flow into the west, and materials could pour into the east. The Erie Canal helped New York develop into the nation’s largest city.

The building of the canal was paid for entirely by the state of New York. It cost $ 7 143 789, but it soon gained its price many times over. Between 1825, when the canal was opened, and 1882, when toll charges(過運(yùn)河費(fèi)) were stopped, the state collected $121 461 891.

For a hundred years before the Erie was built, people had been talking about a canal which could join the Great Lakes and the Atlantic Ocean. The man who planned the Erie Canal and carried the plan through was De Witt Clinton. Those who were against the canal laughingly called it “Clinton’s Ditch(溝)”. Clinton talked and wrote about the canal and drew up plans for it. He and Governor Morris went to Washington in 1812 to ask for help for the canal, but they were unsuccessful.

Clinton became governor of New York in 1817, and shortly afterwards, on July 4, 1817, broke ground for the canal in Rome, N.Y. The first part of the canal was completed in 1820. As the canal grew, towns along its course developed fast. The length of the canal is 363 miles.

Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy; there’s no need for a lot of scientific terms or expensive lab equipment. You only have to share your children’s curiosity(好奇). Firstly, listen to their questions. I once visited a classroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary(薪水) and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said, “Now that we’re finished with your lists, do you have questions of your own about science?”

After a long pause, a boy raised his hand, “Have you ever seen a grasshopper(蚱蜢) eat? When I try eating leaves like that, I get a stomachache. Why?”

This began a set of questions that lasted nearly two hours.

Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more, children give more logical(符合邏輯的), complete and creative answers.

Thirdly, watch your language. Once you have a child involved in a science discussion, don’t jump in with “That’s right” or “Very good”. These words work well when it comes to encouraging good behavior(行為). But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying “That’s interesting” or “I’d never thought of it that way before”, or coming up with more questions or ideas.

Never push a child to “Think”. It doesn’t make sense, children are always thinking, without your telling them to. What’s more, this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target(目標(biāo)) for your disagreement.

Lastly, show; don’t tell. Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass(放大鏡), and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates(蒸發(fā)), set a pot of water to boil and let them watch the water level drop.

June 26, 2000 — the Human Genome(基因組) Project, a great $3 billion, 15-year task aimed at drawing the genetic(遺傳的) map of humans, is now more than 90 percent completed. The scientific and medical communities(團(tuán)體) are very excited about the chances genetic research provides for getting rid of diseases and prolonging(延長) human life. But those communities and policy(政策) makers also are careful about the scientific door they are opening as the project uncovers the mysteries of life.

For the last few years, the genetic advances in the developing field of biotechnology(生物技術(shù)) have provides material for all kinds of work, but the developments of modern science in unlocking the secrets of the human genetic code(密碼) have opened a world of possibilities for human health, as well as for the popular imagination.

While European and Japanese researchers are making rapid progress in decoding(解碼) human DNA, the leading organization for genetic research is in the United States, which began in 1990, is “unlocking the code” of the human body to learn how to defeat fatal(致命的)diseases. Already, the Human Genome Project has become widely known and praised for finding the genes(基因) connected with terrible diseases as yet(迄今), and making progress toward separating the genes that show a sign of breast cancer or AIDS.

Once these genes are found and studied, researchers can develop new ways to attack infections(傳染), and genetic diseases. Medical companies are very interested in mapping the human genome, as they expect to develop a lot of new drugs for these illnesses.

1. Why did the scientists work hard at mapping the human genome?

A. Because the human genome can destroy many illnesses.

B. Because the human genome's completion can help them get rid of many diseases.

C. Because they wanted to be better known than others.

D. Because the human genome can provide a lot of chances of work.

2. Which country studied the genes most rapidly in the world?

A. Japan.        B. Germany.          C. The United States.     D. China.

3. Which of the following is NOT true?

A. If the genes can be found, scientists can study many new ways to cure illnesses.

B. The scientists have made great progress in connecting the genes with the cancers.

C. Many medical companies show great interest in drawing the human genome map.

D. The United States began the Genes Study early in the 19th century.

4. The author suggests that the Human Genome Project can cause _______.

A. the policy makers to feel very worried and careful

B. the scientists to work harder
