【正文】 漸短 Text 請老師朗讀并講解課文 Notes [1] Between the extremes of good conductors such as silver and copper lay other conductors of reduced conducting ability, and they resist the flow of electrons hence the term resistance. 本句是由 and引導的一個并列句 。 在第一個句子中 ,主語是other conductors of reduced conducting ability， 謂語是 lay，between the extremes of good conductors such as silver and copper 是地點狀語 。 “ such as”是修飾 good conductor。 Notes [2] Resistors which are deliberately designed to handle and radiate large amounts of power are electric cooktops, ovens, radiators, electric jugs and toasters. 本句的主語是 Resistors， 定語從句 “ which are deliberately designed to handle and radiate large amounts of power”修飾Resistors。 在該定語從句中 ， to handle and radiate large amounts of power是一個動詞不定式短語 ， 做目的狀語 ， 修飾謂語 are designed。 Notes [3] Worse, because our resistors are of unequal value the power distribution will be unequal with the greater dissipation in the largest resistor. 文中的 Worse不可照字面理解為 “ 更加糟糕的 ” ， 這里是用來表示程度的大小 ， 即后面所說的內(nèi)容比前面的還要更進一步 。 Notes [4]
