Ⅱ. Mark the following statements with T(true) or F(false) according to the text. 1. Resistors, capacitors form important elements in electronic circuitry. 2. Resistors may be classified as fixed or variable in their type and also as linear and nonlinear. 3. Electrical energy can be stored in an electric field. The device capable of doing this is called a resistor. 4. Capacitors are generally divided into classes according to their dielectric. 5. The ability of a capacitor to store electrical energy is termed capacitance. 6. An inductor is formed by winding wire around a suitable mold to form a coil. Ⅲ. Fill in the blanks with the proper form of the word given in the brackets. 1. Resistors may be as fixed or variable in their type. (classify) 2. The higher is the frequency the is the capacity reactance. (low) 3. An inductor is formed by wire around a suitable mold to form a coil. (wind) 4. In an inductor, the voltage is to the time rate of change in the current. (proportion) Ⅳ. Translate the following sentences into Chinese. 1. It is essential to know something about resistance, capacitance and inductance. 2. A resistor is a two-terminal element. Between its terminals it exhibits a voltage drop that is directly proportional to the current passing through it. 3. It is important to remember that capacitance is never constant, except under certain fixed conditions. 4. In an inductor, the voltage is directly proportional to the time rate of change in the current. Translating Skills 科技英语翻译方法与技巧——省略译法 一、省略代词 1.
