Classification辅音，顾名思义，为辅助之音。辅音与元音相对，但与元音的“核心”作用相比，辅音主要是起辅助作用的。英语中，辅音是不可以单独存在的，需要和元音一起构成音节，如/i:/(me),/g/(go)。英语辅音一共有28 个，其中包括两个半元音。辅音在发音时有以下特点：（1）从肺部呼出的气流在通过口腔或鼻腔时遇到阻碍（发元音时不受任何阻碍）。（2）气流较强（发元音时气流较弱）。（3）阻碍部分肌肉较紧张（发元音时肌肉均衡地保持紧张）。（4）不如元音清晰响亮。Unit 2 Unit 2 ConsonantsConsonants2.1Consonants and the Simple
