Ⅲ. Read and write. John 和 Lily 正在谈论学习方法，他们提到了哪些学习英语的好方法呢？用所给单词的正确形式补全对话。
John: Hi, Lily. You did a great job in yesterday's English class! You (sing) the song beautifully.
Lily: Thank you. I (be) afraid to speak English before, but now I'm much more confident.
John: How did you overcome that?
Lily: I often practiced (speak) English with my friends.
John: That's a good way. What else did you do?
Lily: I (watch) English videos. That helped a lot.
John: I see. You can also (join) an English club. I think you'd really enjoy it.

sang; was; speaking; watched; join

1. 第一空：动作发生在昨天的英语课上，是过去发生的事情，要用一般过去时，sing的过去式为sang。
2. 第二空：句中before表示描述过去的状态，主语是I，对应的be动词过去式用was。
3. 第三空：固定搭配practice doing sth. 意为“练习做某事”，因此speak要变为动名词形式speaking。
4. 第四空：此处描述过去的行为，要用一般过去时，watch的过去式为watched。
5. 第五空：情态动词can后面需要接动词原形，因此直接使用join。

Ⅳ. Read and choose. 看图，用短语的正确形式填空。

1. speaks English online
2. asked Lily for help
3. listening to English songs
4. practice a lot

1. 第一幅图是女孩对着电脑练习英语，主语Mira是第三人称单数，often表示一般现在时，谓语动词要使用第三人称单数形式，对应短语选speak English online，变形为speaks English online。
2. 第二幅图是男孩向女孩求助英语，时间状语yesterday表示句子为一般过去时，谓语动词要用过去式，对应短语选ask Lily for help，变形为asked Lily for help。
3. 第三幅图是女孩戴耳机听音频，be动词is后可以接动名词作表语，对应短语listening to English songs本身是动名词形式，无需变形。
4. 第四幅图是男孩踢足球，情态动词must后面要接动词原形，对应短语practice a lot本身是原形结构，无需变形。
