New Words And Phrases resistance [ri5zist[ns] n.阻力，电阻，阻抗 copper [5kCp[] n..铜 mica [5maik[] n.云母 insulator [5insjuleit[] n.绝缘体 conductor [k[n5dQkt[] n.导体 resist [ri5zist] n.阻抗 ohm [[um] n.欧姆 Nickel [5nikl] n.镍 Nichrome [5naikrum] n.镍铬合金 New Words And Phrases voltage [5vaultidV] n.电压，伏特数 series [5si[ri:z] n.连续，串联 parallel [5pAr[lel] n.平行线，并联 halve [ha:v] vt.二等分，平分 cooktop [5kuktCp] n.炉灶 oven [5Qvn] n.烤箱 radiator [5reidieit[] n.散热器，冰箱 jug [dVQg] n.水壶 toaster [5tust[(r)] n.烤炉 capability [9keip[5biliti] n.能力，性能，容量 New Words And Phrases material [m[5ti[ri[l] n.材料，原料 ampere [5AmpZ[] n.安培 formula [5fC:mjul[] n.公式，规则 dissipate [5disipeit] n. 耗散，vt.使……消散 distribution [distri5bju:F[n] n.分配，分发 dissipation [9disi5peiF[n] n.消散，分散 wattage [5wCtidV] n.瓦特数 precision [pri5siV[n] n.精确 stem [stem] n.茎，干 New Words And Phrases accuracy [5Akjur[si] n.精确性 confusion [k[n5fju:V[n] n.混乱 accommodate [[5kCm[deit] v.容纳，使……适应 explanatory [iks5plAn[t[ri] adj.说明的，解释性 between…and 在……之间 on the other hand 另一方面 take advantage of 利用 close in 包围, 封闭, 渐短 Text 请老师朗读并讲解课文 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引导的一个并列句。在第一个句子中,主语是other conductors of reduced conducting ability， 谓语是lay，between the extremes of good conductors such as silver and copper 是地点状语。“such as”是修饰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. 本句的主语是Resistors，定语从句“which are deliberately designed to handle and radiate large amounts of power”修饰Resistors。在该定语从句中，to handle and radiate large amounts of power是一个动词不定式短语，做目的状语，修饰谓语are designed。 Notes [3] Worse, because our resistors are of unequal value the power distribution will be unequal with the greater dissipation in
