辅音连缀
在英语词汇中，如果有两个或两个以上的辅音音素结合在一起，这种语法现象称为辅音连缀。辅音连缀发生在词首，词中和词尾。如：
词首 blue
词中 basketball
词尾 desk
读辅音连缀时，两个辅音不能有停顿，几乎同时发音，前面的辅音必须读得轻一些，短促些。
Listen and repeat. Notice the difference in stress and meaning of the same sentence.
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)

句子重音
在英语句子中,实词(如名词、动词、形容词、副词等)承载重要信息,一般需要重读;而充当语法功能的词(如冠词、连词、介词、助动词等)一般弱读。但这条读音规律并非一成不变,句子中的重音可以随着说话者要表达的意思的变化而变化。例如:
'I didn't say he stole the money.(强调“不是我说的”)
I didn't say 'he stole the money.(强调“不是他偷的”)
I didn't say he 'stole the money.(强调“不是偷,可能是借的”)

句子重音
句子重音可分为三类：表意重音，逻辑重音和情感重音。
表意重音 表意重音是一种非常普遍的现象。一般来说，在句子中需重读的词都是实词，不重读的词多为虚词或结构词。
逻辑重音 逻辑重音的作用是表达说话者的意愿，说话者可以把重音放在想要强调的任何单词上。
情感重音 情感重音是一种特殊的重音。在口语中，当说话者想要表达强烈的情感时，他会把强重音放在他想要强调的词上。

3. Why did you choose it
First, it’s super common and familiar—almost everyone has seen or even kept it at home. That makes it easy to find information and talk about.
Second, it’s "amazing" in its own way. It grows well in water or soil, tolerates low light, and stays green all year. Even if you forget to water it sometimes, it still lives. Its trailing vines look beautiful too.
Third, it fits the unit theme "Amazing Plants and Animals". It shows how plants can adapt and bring beauty to our daily life.
