1) “n” 发音:/n/,舌尖抵上齿龈,气流从鼻腔中出来。
例词:nose(鼻子)、nine(九)、no(不)、nap(小睡)
2) “p” 发音:/p/,双唇紧闭,然后快速张开,让气流冲出,声带不振动。
例词:pear(梨)、park(公园)、pen(钢笔)、pin(大头针)
2. 发音练习
1) 短语练习:nice nose(漂亮的鼻子)、pink pen(粉色的钢笔)、nine pandas(九只熊猫)、purple pencil(紫色的铅笔)
2) 句子练习:I have a nice nose.(我有一个漂亮的鼻子。);She has a pink pen.(她有一支粉色的钢笔。)
【大显身手】

押韵词指单词末尾的元音和辅音发音相同,前面的辅音发音不同。
例:“tall”(高的)和 “ball”(球)押韵,结尾都发 /ɔːl/;“great”(棒的)和 “eight”(八)押韵,结尾都发 /eɪt/。
2. 常见例子(来自单元内容)
1) 单元中 “tall” 与 “ball” 押韵,可拓展其他同类单词:wall(墙)、small(小的)
2) 拓展:“kite”(风筝)与 “bite”(咬)押韵,“robot”(机器人)与 “not”(不)押韵
