二、英语句子的重音和节奏
英语句子听起来之所以忽轻忽重,忽快忽慢,忽升忽降,富有节奏感,主要是因为句子重音、节奏和语调的重要调节作用。
英语句子的重读规律是:重读音节与非重读音节相间出现。
重读音节与紧跟其后的非重读音节一起组成节奏单位(群)。
在不受迟疑(可使人说话速度放慢)或激动(可使人说话速度加快)等因素影响的情况下,话语中句子重读音节之间的间隔时间大致相等。
也就是说,根据英语的节奏规律,话语说起来所需的时间不取决于它有多少个词,多少个音节,而取决于它有多少个句子重读音节。
假如句子重读音节之间的非重读音节数多,结果必然是说起来要快一些,含糊一些。
练习英语话语节奏的重点是:学会顺利地、匀称地从一个重读音节移动到下一个重读音节,特别要学会使用弱势读音和连读等方法,把重读音节中间夹带的非重读音节读好。
