本题考查根据语境选择恰当单词填空的能力，需注意以下关键点：

1. 词性转换：根据句子结构判断所需词性（如名词、动词等）；
2. 固定搭配：如“take measures to do sth”；
3. 语境逻辑：结合上下文理解空格处应表达的核心含义；
4. 习惯用法：如“electric power”是常见搭配。

1. The good news got ______ from the audience.

关键点：动词get后接名词作宾语，表示“欢呼、喝彩”的抽象概念，用不可数名词cheer。

2. These factories will take every possible ______ to reduce pollution.

关键点：固定短语take measures to do sth（采取措施做某事），需用名词measure。

3. Waterfalls can be used to produce ______ power.

关键点：水力发电产生的是电力，electric作形容词修饰power。

4. Can you come to the party to ______ Jim's graduation?

关键点：不定式作目的状语，表示“庆祝毕业”，需用动词原形celebrate。

5. It's a(n) ______ to sing "Jingle Bells" at Christmas.

关键点：表示“传统”，tradition是可数名词，与不定冠词a搭配。

6. These classes help members learn how to change their eating ______.

关键点：表示“饮食习惯”，habit是可数名词，复数形式habits表示类别。

7. In some way, he ______ several of his friends in the trouble.

关键点：主语he为单数第三人称，动词需用第三人称单数形式involves。

8. In the end, he realized the ______ of foreign languages.

关键点：表示“重要性”，importance是抽象不可数名词。
