A dam is a man-made structure built across a river. Most dams are built to control a river’s water flow, improve navigation and control flooding. However, some dams are built to produce hydro-electric power.

Hydro-electric power is produced as water passes through a dam, and into a river below. The more water that passes through a dam, the more energy is produced. Once a dam is built, a man-made lake is created behind the dam.

Electricity is produced by a kind of equipment called a turbine(水轮机). Turbines contain metal coils(线圈) surrounded by magnets(磁铁). When the magnets move round rapidly over the metal coils, electricity is produced. Turbines are located inside dams. The falling water makes the magnets go around the coils.

Dams provide clean energy, but they can also harm the environment. Species that use rivers to reproduce are often hurt by dams. In the Northwest of the US, the population of fishes has dropped from 16 million to 2.5 million since hydro-electric plants were built on the Columbia River. Dams all over the world have hurt some species. 

  The highest dam in the Unites States is located near Oroville, California. The Oroville Dam towers 230 meters and is more than a mile wide. This dam was built in 1968, 22 years after the Hoover Dam. The Hoover Dam, on the Nevada-Arizona border controls the Colorado river. It is 221 meters high and has 2.6 million hectare-meters of water.

The highest dam in the world is the Nurek Dam on the Vakhsh River in Tadzikistan, a country in central Asia. This dam is 300 meters tall. 

Which of the following statements is NOT true according to the passage?              

A. Some dams are built for controlling a river’s water flow.

B. Hydro-electric power is usually produced through a dam.

C. Dams can offer energy and they are harmless to the environment.

D. Generally speaking, where there is a dam, there is a man-made lake.

The third paragraph mainly tells us _____.                          

  A. how hydro-electric power is produced

  B. What a turbine is and how it works 

  C. how the magnets and the metal coils work

  D. how the falling water passes through a turbine                     

The dam which controls the Colorado river is ____.                  

A. the Oroville Dam  B. the Hoover Dam  C. the Nurek Dam  D. the Vakhsh Dam

Over a hundred years ago people in London were surprised to see a very unusual boat come sailing up the Thames River. The boat was eighty feet long flat-bottomed, with big wooden eyes on both sides in the front and was colorfully painted at the back.
People came to know that it was a sailing boat from Fuzhou in distant China. The boat had sailed round the Cape of Good Hope(好望角) up the western coast of Africa, and finally to England. It had covered fifteen thousand miles—more than half of the distance round the world.
Although it was unexpected, the Chinese were warmly welcomed. The boat carried goods such as silk and tea as well as a number of gifts from the Emperor of China for the Queen of England.
People had always mistakenly thought of the Chinese as a people not used to sea. However, from centuries of trading and sailing in dangerous seas, the Chinese had learned how to build good boats and sailed them well. The coming of this sailing boat to London proved once again that the Chinese could sail to distant countries in the world.
【小题1】The boat was considered unusual because _________.

My father’s family name being Pirrip, and my Christian name Philip, my infant tongue could
make of both names nothing longer or more explicit than Pip. So, I called myself Pip, and came to
be called Pip.
As I never saw my father or my mother, and never saw any likeness of either of them (for their days were long before the days of photographs), my first imagination regarding what they were like, were unreasonably from their tombstones. The shape of the letters on my father’s gave me a strange idea that he was a square, dark man , with curly black hair. From the character and turn of the words, “Also Georgiana Wife of the Above,” I drew a childish conclusion that my mother was freckled（长雀斑的）and sickly.

Suddenly I began to feel lonely and sad and afraid. I began to cry.
"Hold your noise!" cried a terrible voice, as a man started up from among the graves at the side of the church porch. "Keep still, you little devil, or I'll cut your throat!"
A fearful man, all in grey, with a great iron on his leg. A man with no hat, and with broken shoes, and with an old rag tied round his head. A man who had been shivered; and whose teeth chattered in his head as he seized me by the chin.
"Oh! Don't cut my throat, sir," I pleaded in terror. "Pray don't do it, sir."
"Tell us your name!" said the man.  "Quick!"
"Pip, sir."
"Once more," said the man, staring at me.  "Give it mouth!"
"Pip. Pip, sir."
“Show us where you live ,” said the man. “Point out the place!”
I pointed to where our village lay, among the alder-tree, a mile or more from the church. The man, after looking at me for a moment, turned mw upside down, and emptied my pockets. There was nothing in them but a  piece of bread. When the church came to itself—for he was so sudden and strong that he made to go head over heels before me, and I saw the steeple（尖塔）under my feet—when the church came to itself, I say, I was seated on a high tombstone, trembling, while he ate the bread hungrily.
“You young dog,” said the man, licking his lips, “what fat cheeks you have got.”
I believe they were fat, though I was at that time undersized for my years, and not strong.
“Darn me If I couldn’t eat them,” said the man, with a threatening shake of his head.
I carefully expressed my hope that he wouldn’t, and held tighter to the tombstone on which he had put me; partly, to keep myself upon it; partly, to keep myself from crying.
“Now look here!” said the man. “Where’s your father?”
“There sir!” said I .
He started, made a short run, and stopped and liked over his shoulder.
“There sir!” I explained. “That’s his grave.”
“Oh!” said he, coming back.
“And mother’s there too, sir. And my five little brothers.”

My father’s family name being Pirrip, and my Christian name Philip, my infant tongue could

make of both names nothing longer or more explicit than Pip. So, I called myself Pip, and came to

be called Pip.

As I never saw my father or my mother, and never saw any likeness of either of them (for their days were long before the days of photographs), my first imagination regarding what they were like, were unreasonably from their tombstones. The shape of the letters on my father’s gave me a strange idea that he was a square, dark man , with curly black hair. From the character and turn of the words, “Also Georgiana Wife of the Above,” I drew a childish conclusion that my mother was freckled（长雀斑的）and sickly.

Ours was wet country, down by the river, within, as the river wound, twenty miles of the sea. My first most vivid and broad impression of the identity of things, seems to me to have been gained on an unforgettable cold afternoon towards evening. At such a time I found out for certain, that this place overgrown with nettles（荨麻）was the churchyard（墓地）;and that Philip Pirip, and also Georgiana wife of the above, were dead and buried; and that Alexander, Bartholomew, Abraham, Tobias, and Roger, infant children to the aforesaid, were also dead and buried.
