Добрый день, очень тяжкое положение с английским языком, в связи с его не знанием). Прошу помочь ответить на вопросы по тексту, сроки уже в край бьют, котелок не додумывается, за ранее благодарен.

Hundreds of electronic eqllipmcnts arc now used for scientific,
industrial and everyday pllrposes. They l1clp to do jobs better or more
rationally than before and take over jobs that coLJidn't Ье done otherwise.
So, industrial electronics LJndouЬtedly plays а vcry important role today.
You can easily find many electronic eqllipments at lюme: а tape recorder,
а ТV set, an МРЗ player, а computer and many othcrs.
The application and use of electronic eqllipments dcmands а good
knowledge of their fundamentals.
In meters and lamps electricity flows in the wire. Bllt inside any
transistor or microcblp (and previously, in radio tubes) electric current
passes through the space (or semiconductor) separating certain parts in
tbls detail. Such action is called electronic. lt's not difficult to imagine it
because the same happens in lightning. There you actually see how
electricity jumps through space.
The first electronic equipments used radio lamps. They were: а radio
set, а ТV set, computing machines (predecessors of modem calculators),
computers (wblch occupied Ьig rooms), tape recorders.
The next stage came when transistors were invented. The devices
became more powerful and much smaller. The number of devices increased
greatly, some multifunctional devices appeared (radio + tape recorder).
Computers and calculators became smaller: cassette recorders and videocassette
recorders appeared.
The next period was the period of microcblps. They helped to reduce
big parts of devices, computers and other devices.
Тhе latest period of industrial electronics development is the period of
total digitization of all electronic devices, making them compatiЬle with the
computer. Photos are no longer made on film but on memory cards, cassettes
and video cassettes are out of use. Television is also becoming digital.
Industrial electronics is а great part of our leisure time, it makes
people's lives easier, and reduces their working time.

1. For what purposes are electronic equipments used now? What do
they help us to do?
2. Industrial electronics plays an important role today, doesn't it?
3. What electronic equipments are usually found at home? What can
you find at home?

переведите текст Once upon a time there was a chief who had a beautiful daughter. Many young men wanted to marry her, but the chief thought: "They are not very good for my daughter." Fire and Rain wanted to marry her, too. Rain came to the chiefs daughter and said, "Will you marry me, oh daughter of the Chief?" "Yes, I will," said the girl. At the same time Fire came to the chief and said, "I want to marry your daughter. Will you give her to me for my wife?" The chief said, "Yes, I will." Then the chief sent for his daughter and said to her, "My dear daughter, you will marry Fire. I gave him my promise."
"Oh, Father," said the girl, "I cannot marry Fire, I must marry Rain. I gave my promise to him."
"What shall we do?" cried the chief. "You can't marry both Fire and Rain."
Then Fire and Rain came to the chief and his daughter. The chief said to them:
"Tomorrow will be the day of my daughter's marriage."
"To me?" asked Fire.
"To me?" asked Rain.
"To the winner of a race. To him I will give my daughter."
On the day of the race many people came to the town. They all wanted to see the race. Some of them said, "Fire will win." Others said, "Rain will win."
But the chiefs daughter thought: "I want to marry Rain."
The day of the race came. When it was time to begin, the drummers beat the drums. The race began. The wind helped Fire to run very quickly. But where was Rain? Nobody saw him. The people cried:
"Look, Fire is quite near the finish!"
But then Rain began to fall from the sky and put out Fire.2 So Fire could not finish the race. The people cried:
"Rain, Rain is the first!"
So the chief gave his daughter to Rain, and they were very happy.
And from that day on Fire and Rain are enemies.
