[00:28.92]THE OFFICE
[00:31.48]Offices cannot work properly
[00:35.34]without certain important pieces of equipment.
[00:39.89]One of the first jobs when you start work in an office
[00:44.85]is to learn how to use every piece of equipment.
[00:49.61]Once you have done this,
[00:52.77]you will quickly become a useful member of the team.
[00:57.42]It is better to ask for help at the beginning
[01:02.59]rather than to wait until a busy period
[01:06.95]when everyone is rushed off their feet.
[01:11.00]The fax has greatly changed office work, especially in China.
[01:17.84]When you place a sheet of paper in a fax machine,
[01:22.70]the machine "reads" the writing on the page
[01:27.56]and changes the shapes of letters into electronic signals.
[01:33.20]It then sends these signals down an ordinary telephone line
[01:38.87]to another fax machine
[01:42.03]which changes the signals back into the shapes of letters.
[01:47.00]You can imagine how useful this is,
[01:50.76]particularly in countries like China and Japan,
[01:55.62]which use written characters not letters
[02:00.06]It is also useful for sending pictures,designs,maps and so on.
[02:06.30]Sending a fax is more expensive than posting a letter,but much quicker.
[02:12.96]For example,you can send information abroad immediately,
[02:18.61]but mailing a letter might take a week or so.
[02:23.18]If you want to send a letter to an office abroad
[02:27.62]that is in a different time zone,
[02:31.28]you can send a fax,
[02:34.44]and it will be received even though the office is not open.
[02:39.61]There are two other points to consider.
[02:43.37]First,remember that a fax can be read by anyone,
[02:48.41]so be careful what you send!
[02:51.89]Second,do not start faxing everything!
[02:56.56]It is much cheaper to post or email a long report than to fax it.
[03:02.80]This makes copies,using a mirror,a roller and special black powder.
[03:09.88]Modern machines can make the copy bigger or smaller,
[03:15.24]lighter or darker and copy onto both sides of the paper.
[03:20.49]It can copy a long report and sort the copies and pin them together.

[03:26.16]There is a new type of machine which can produce colour copies.
[03:31.72]All machines are slightly different,
[03:35.38]so you need a short lesson when you start work in a new office.
[03:41.23]This combines a typewriter keyboard,a printer and a computer.
[03:48.08]When you type a letter,
[03:51.24]the writing appears on a screen in front of you
[03:55.60]and is recorded onto a computer disk.
[03:59.86]When you have finished the letter,
[04:03.23]you make any changes you wish,check it and print it.
[04:08.58]If it is a long report,it is easy to make changes to the text.
[04:14.33]Then,instead of spending maybe five hours typing the report again,
[04:20.99]you can print the new copy in one minute!
[04:25.06]This is a telephone with a tape recorder.
[04:29.61]When there is no one in the office,
[04:33.27]you can leave the answering machine on
[04:37.34]so that people who call you up can leave a message.
[04:41.89]When you return to the office
[04:45.23]the following morning or after the holiday,
[04:49.31]you can listen to the messages and take any necessary action.
[04:54.56]Many offices use answering machines to give information.
[04:59.89]Imagine a railway station,a bus company or a cinema,
[05:05.35]which many people need to ring to find out the times of trains,
[05:10.62]buses or films.
[05:13.68]You can print the telephone number
[05:17.15]of your information service in the newspaper.
[05:21.41]Then,instead of having some one answering the phone all day,
[05:27.05]people can ring up the railway station
[05:30.89]and listen to a tape recording of the information.
[05:35.28]What is more,this "information line"operates 24 hours a day.
[05:41.81]Lesson 70 1 Reading comprehension
[05:45.04]第七十课 1 阅读理解
[05:48.26]Read the text fast to find answers to these questions.
[05:53.83]1 Where did the fire happen?
[05:56.21]1 火灾发生在哪里?
[05:58.58]2 What started the fire?
[06:00.80]2 什么引起火灾的?
[06:06.37]A navy ship was in a port in Scotland for repairs.
[06:12.01]It was important to carry out the work quickly,
[06:16.58]so an extra team of men were asked to work on the repairs one evening.
[06:22.46]They had to work inside the ship,cutting away old metal,
[06:28.10]fixing new metal plates,drilling holes,
[06:32.96]laying electrical and phone wires
[06:37.04]and fixing new pipes for water and steam.
[06:41.58]The team started work on a new section inside the ship near the front.
[06:47.46]One man was told to fix up an "air-line"

[06:52.11]to provide compressed air for the machines they were using.
[06:57.15]It took him some time to connect the long rubber pipe
[07:01.90]to the air supply pipe
[07:05.06]that ran round the port,
[07:08.23]but at last it was done
[07:11.46]and as a result work was able to progress much faster.
[07:17.03]After three hours,the men stopped for a meal break.
[07:22.17]When work continued,one man lit a cigarette as he was working,
[07:28.05]but,finding it had a strange taste,he put it out.
[07:33.62]Another man lit a cigarette
[07:36.96]but it burnt strangely and so he too put it out.
[07:42.39]Half an hour later,another man struck a match for a cigarette
[07:47.96]and this time the whole of the inside of the ship caught fire.
[07:53.60]As quickly as they could,
[07:56.76]the men ran to the steps and up into the open,
[08:01.62]many of them with their clothes on fire.
[08:05.38]Most of them were able to climb out in time.
[08:09.51]However four men were not quick enough to escape the flames
[08:15.46]Their burnt bodies were found later.
[08:19.44]It did not take the firefighters long to put out the fire,
[08:24.69]and they at once started to look for causes of the fire.
[08:29.44]They were puzzled by several things.
[08:33.28]It appeared that a fierce fire had taken place inside the ship,
[08:39.13]but without damaging the walls.
[08:43.10]There had been fuel on the ship,
[08:46.45]but this did not appear to have caused the fire,
[08:50.60]and little smoke was produced.
[08:53.97]The men who had been working on the repairs
[08:58.02]mentioned the curious way their cigarettes burned and tasted.
[09:03.19]The fire service began to wonder whether a gas might have caused the fire.
[09:08.94]The question was,which one?
[09:12.91]It must have been a gas that could burn but that would not explode,
[09:18.26]a gas that did not smell strong,and a gas that did not kill people.
[09:24.11]The man who had fixed up the air-line was also questioned.
[09:29.18]He explained that he had tried to fix the air-line to the supply line
[09:34.82]that ran round the port but could not because the fittings did not match.
[09:41.07]So he had gone to the stores and had obtained a fixture
[09:46.11]that fitted both the tap on the supply line and the end of the air-line.
[09:52.27]Once he had done this,he had been able to turn on the supply.
[09:57.73]They then knew that they had discovered the cause of the fire.
[10:02.49]The man had connected the air-line to a supply line of oxygen

[10:08.34]not compressed air.
[10:11.58]Oxygen is widely used in ship repairs
[10:16.25]for cutting and joining metal plates or pipes.
[10:20.90]While the men had been working inside the ship,
[10:24.98]the air-line had been giving off oxygen.
[10:29.05]Once the oxygen content of the air had risen to 25%,it was ready to burn.
[10:36.71]The third person who lit a match started the fire.
[10:41.57]It was noticed that there were no signs or warnings on the supply lines
[10:46.64]that ran round the port.
[10:50.16]After the accident,all the lines and taps were clearly marked
[10:56.01]and new people joining the workforce
[10:59.98]were given a talk on safety before they started work.
