1.1 什么是专业英语
普通英语（Common English, Ordinary Englபைடு நூலகம்sh）
科技英语（English for Science and Technology）
翻译:当然在许多其他领域如医药、交通、科学、商业等行业也取得 很大进步，但如果没有电子提供的仪器和器件，这些行业能取得 这么大的进步吗？
这是一个带有一对并列句和一个从句组成的长句。其中they 指的都是great advances。在科技英语中，要注意it, that, which等词的指代，有时要结合自己的专业知识来翻译。
① 动名词
✓用动名词短语取代时间从句或简化时间陈述句
1)The signal should be filtered before it is amplified. The signal should be filtered before being amplified.
2) An object becomes hot. It is placed in the sun. Once being placed in the sun, an object becomes hot.
3) The transistor, which is working with correctly polarities, can work as an amplifier.
The transistor working with correctly polarities can work as an amplifier.
✓用动名词短语做主语
4) Changing resistance is a method for controlling the flow of the current. 5) Conducting electricity means the flow of electrons through an object.
(4) It句型和祈使句使用频繁 （准确、精炼） It句型：it 充当形式主语，避免句子“头重脚轻” 祈使句: 无主语，精炼。
It is very important (possible, necessary, natural, inevitable) to… It takes very much time learning… It is clear (possible, necessary, natural, inevitable) that… It happened that … It must be admitted that…

2) A three-phase circuit, as it was pointed out above, is merely a combination of three single-phase circuits.
A three-phase circuit, as pointed out above, is merely a combination of three single-phase circuits.
If possible, the open-loop control approach should be used in this system.
2) As illustrated in Fig.1, there is a feedback element in the closedloop system.
As previously mentioned 前已提到 When needed (necessary, feasible)必要时 Where feasible 在实际可行的场合
If possible (necessary)如果可能（必要） Where possible 在可能的情况下
