Light for the City
Edison and his assistants came to New York to set up an electric power system. They hoped it would provide enough electricity to light up a part of the great city.
They bought several machines with them. These were called generators(发电机), which produced electricity power for lamps in Edison’s building.
Soon there were lights for the building. Edison lived in a room facing the street and he often worked over night. The light burned brightly and steadily and he often worked over night. People often came and stopped their horse-drawn carriage to look. Everyone knew that Thomas Edison was in town.
First, the inventor and his assistants produced several large generators. A great deal of power would be needed to light up even a small part of the city. Then the workers were busy digging deep trenches in the hard earth below the city streets, and Edison had fourteen miles of wire laid into the trenches. The wire connected each building to a generator.
Setting up an electric power system was not an easy job. It took a year and a half. In September, 1882, the job was finished.
A small group of men stood around Edison inside the power house. The big moment came at last. The inventor, taking a deep breath, pulled a switch. The electric lights flashed up.
“Very good! Very good!” a man nearby shouted to praise Edison for what he had done.
“Sir,” said Edison, “this is only the beginning!” And Edison was right. Soon Edison’s lamp were lighting up cities all over the world.
1.The generators they brought with them could produce as much as electricity as ______ needed.
A.Edison’s building | B.a small part of the city |
C.the whole city | D.the world |
2.Trenches were dug to ______.
A.set up generators | B.lay wires | C.built city streets | D.build a power house |
3.It took a year and a half to ______.
A.set up the electric system |
B.produce several large generators |
C.dig the deep trenches |
D.lay fourteen miles of wire into the trench |
4.Edison took a deep breath before pulling a switch, which showed that he was ______.

If you’re DIY-minded, you can build your own solar power system. In some cases, you can even build your own solar panels (电池板), although the amount that you can effectively DIY home solar depends on how much you want to power. Making your own solar panel is a time-consuming process and requires some electrical skills. However, it can also be very rewarding-learning to build your own panel is a great way to understand how solarelectricity is generated.
Before you can build your own solar panels, you first need to understand how solar cells generate electricity. Once you’ve bought individual solar cells (they can be purchased online), the basic process for building your own solar panel goes like this: Prepare the backing for your panel. Many DIY solar panel builders prefer to use a wooden board as the base for their solar cell. You’ll need to drill holes in the board so that the wires for each cell can pass through. Wire your solar cells together. This requires some experience with electrical work. Use a soldering iron (烙铁) to attach wire to the solar cells and then link each of the cells together. Attach cells to your backing. If possible, attach each solar cell to the backing individually. This makes it easier to replace a single cell in the event that becomes damaged or is not operating properly.
At this point you have a functional solar panel that can produce electricity when the sun shines. However, a solar panel by itself is not useful. If you are trying to generate electricity to power devices in your home, you need to pair your panel with an inverter (换流器) that will turn direct current (DC) power from the sun into the alternating current (AC) power used in most modern electronic devices.
1.What does the author think of building DIY solar panel in the first paragraph?
A.It is easy. B.It is necessary. C.It is common D.It is worthwhile
2.What’s the first step of building your own solar panels?
A.Master the advanced knowledge- of management.
B.Buy individual solar cells.
C.Prepare the backing for your panel.
D.Drill holes in the wooden board.
3.Why are solar cells connected to the wooden board separately?
A.To produce more power.
B.To substitute damaged cells easily.
C.To attach cells to the backing tightly.
D.To pass through the wooden board easily.
4.What can be inferred from the text?
A.People with electrical skills have advantages over those without in DIY solar panels.
B.A functional solar panel can give power to your home devices directly.
C.How to pair an inverter depends on how much you want to power.
D.a wooden board is a must for your own solar panels.

The national assistance system for poor college students is getting more effective as proved by fewer phone calls to the hotline of the National Center for Student Assistance Administration.
"Poor college students and their parents are getting more satisfied with the national assistance system," said Ma Wenhua, deputy director of the administration, on Saturday. Over the past three years, the hotline received 8,488 calls. Statistics show 62 percent of the calls were made to ask about the funding policy, while 38 percent (3,200 calls) complained local colleges had failed to abide by the rules to support the students.
Complaints were seen a year-on-year decrease from 2006 to 2008. Ma said some poor families might still overlook what they should do to get support for their child. To ensure education equality, the government has introduced a set of favorable policies to help poor students, such as scholarships, grants, student loans, tuition waivers(学费全免) and the work-study programs under which poor students are helped out in libraries, teachers' offices or service departments to earn money.
Statistics show the government spent 29.3 billion yuan last year to aid college students, up 7.6 percent from the previous year. Around 40 million persons of college students received the national aid.
The Ministry of Education of the government would ensure that no students drop out of colleges or universities because of poverty.
Among the 20 million students in the country's public and private universities and colleges last year, about 20 percent came from poor backgrounds, official figures show.
1.The national assistance system is set up ___.
A. for parents and students to complain
B. to help poor college students
C. for poor students to get free education
