  I Just want to recite the article I 've read today. I know reciting and repeatation are good teachers.
   If I can recite and repeat about 100 articles of IELTS's Reading,Listening ,Writting and Oral English . IELTS should not be a difficult task for me .

Although the principles behind the developement of Autoguide are straightfoward, 虽然自动导航系统的原理很浅显.
TRRL did run into problems when it was testing the system.
TRRL在测试系统的时候,发现了一些问题
In a Cavalier ,researchers could not get the electronic unit in the car to communicate with the one in the ground.
在"骑士"车的测试中,研究者发现车上的电子装置无法和地下的电子装置联系
Eventually, they discovered that the alternator in the car was operating at a frequency which was a multiple of that of the radio wave being used for communication.
最终,他们发现车上的交流电机运行的频率正好是和交流电波频率的整倍数.
and that the alternator was interfering with the data transmission.
交流电机干扰了数据传输
The problem was solved, however ,by adding a capacitor to the alternator.
给电机加一个电容,问题就解决了.
TRRL is now ready to start some experiments in london and says that a full-scale system could be installed by 1990.
TRRL已经准备在伦敦做一些实验,自动导航系统就在1990左右全面实行.

Initially, TRRL would like to see this sort of system tried out in london. But installing the electronic units in the ground and leasing telephone wires would cost $15 million. The departement of Transport believes that , although the trafic congestion could be reduced, the electronics companies should pay for this infrastructure and recoup this outlay by selling the car units and charging a license fee. Only people who paid for the personal identification number similar to those issued by credit card companies could use this system.

Autoguide ,goes one step further by monitoring the effect of its own advice.
without such a crosscheck , the system will create trafic congestion and slow drivers down by sending them all to the same route. The crosscheck is achived simply by timing the driver's journey, between the successive electronic units in the ground, then incorporating this information into the calcullations.
