I visited the redwood forests in California several times. 标绿的 redwood 读重音（声音响、拖长一点），意思是： → 我去的是红杉林，不是其他森林（比如松树林、柏树林）！ 读的时候，夸张把 “redwood” 重读，其他词轻读，对比感受。 2. I visited the redwood forests in California several times. 标绿的 California 读重音，意思是： → 我去的是加州的红杉林，不是其他地方的 重读 “California”，强调地点的唯一性。 3. 第三句：I visited the redwood forests in California several times. 标绿的 several 读重音，意思是： → 我去了好几次红杉林，不止一次！ 带读技巧：重读 “several”，突出次数多。 课堂总结 We learn: 1.
