Pronunciation
2. Listen and repeat. Notice the difference in stress and meaning of the same sentence.
核心概念：
句子重音改变语义（一句话，重音不同，意思不同！）
I visited the redwood forests in California several times.(not other forests)
I visited the redwood forests in California several times.(not other places)
I visited the redwood forests in California several times.(not only once
1.：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。
