动名词(续2)
一、关于动名词复合结构的注意事项 1.“there be”句型的的名词复合结构 A current flows through the resistor(电阻器) as a result of(由于) there being a potential(电位) difference(差) across it. The chances(可能性) of there being one civilization(文明社会) close(接近) to us are not very great. 2. 有时候动名词复合结构中由连系动词(be)变来的“being”可以省去 The reason(原因) lies in(在于) the product(产品) more stable(稳定的).
Look about(环视) you and you will see proof(证据) of electrically(由电方法) generated(产生的) energy in action(在起作用). Operation(工作) beyond(超出) this hyperbola(双曲线) will result in(导致) diode(二极管) power(功率) dissipation(消耗) in excess of(超过) its maximum(最大的) rating(额定值) of 1W. 3.当在“-ing”的前面有一个普通格的名词时不一定构成动名词复合结构，只能根据整个句子的含义来确定 A circuit(电路) can be broken(断开) by a switch(开关) being opened.
二、动名词名词化 有的动名词失去了动词特征，作为普通名词来用，其前面有冠词等存在但仍有动词的含义 Models(模型) help in the understanding(理解) of the physical operation(物理性能) of a system(系统). This changing of AC into DC is called “rectification”(整流).
The controlling(控制) of the temperature is a typical(典型的) example of a feedback(反馈) control system. This makes the output(输出) of the AND gate(与门) the ANDing(使相与) of the complements(补数) of the input(输入) variables(变量).
