1. Look! The birds (fly) madly in the park.
2. Ssh! The baby (sleep) in the bedroom.
3. Look, the girl (play) games with her pet cat. They are happy.
4. Come and see! That pigeon (look) at itself in the water!
5. At the moment, the Smiths (watch) a TV programme on beavers.

1. are flying 2. is sleeping 3. is playing 4. is looking 5. are watching

【分析】首先观察每个句子，都有明确的现在进行时提示词（如look、ssh、come and see、at the moment），需使用现在进行时结构：am/is/are + 动词现在分词。接下来根据主语的单复数确定be动词的形式，再将所给动词变为现在分词形式，完成填空。
【解析】
1. 句中提示词“Look”表明动作正在进行，主语“the birds”是复数，be动词用are，fly的现在分词是flying，故填are flying。
2. 句中提示词“Ssh!”暗示动作正在进行，主语“the baby”是单数，be动词用is，sleep的现在分词是sleeping，故填is sleeping。
3. 句中提示词“Look”表明动作正在进行，主语“the girl”是单数，be动词用is，play的现在分词是playing，故填is playing。
4. 句中提示词“Come and see!”表明动作正在进行，主语“that pigeon”是单数，be动词用is，look的现在分词是looking，故填is looking。
5. 句中提示词“At the moment”表明动作正在进行，主语“the Smiths”指史密斯一家人，是复数，be动词用are，watch的现在分词是watching，故填are watching。
【答案】
1. are flying 2. is sleeping 3. is playing 4. is looking 5. are watching
【知识点】
现在进行时；主谓一致
【点评】
本题考查现在进行时的基础运用，核心是识别现在进行时的提示词、掌握“be + 现在分词”的结构，以及be动词随主语单复数变化的规则，属于英语基础题型，难度较低。

【分析】
A部分解题思路：先通读短文理解语境，判断时态（如1、2、8题描述研究中心正在进行的动作，用现在进行时）；再结合固定搭配（如learn about）、词性要求（修饰动词用副词）、语法规则（情态动词后接动词原形、动词后用人称代词宾格、名词复数）完成填空。B部分解题思路：先读问题，定位原文细节，第1题根据文章主题（恐龙研究）判断版块；第2题根据原文明确表述找到对应答案。
【解析】
A. 1. 语境为“恐龙研究中心里工人正在清理化石”，用现在进行时，主语workers是复数，故填are cleaning。
2. 同理，“科学家正在观看化石”，现在进行时，主语scientists复数，故填are watching。
3. 固定搭配learn about（了解），故填about。
4. 修饰动词walk需用副词，slow的副词形式是slowly，故填slowly。
5. 情态动词could后接动词原形，故填swim。
6. plant表“植物”时是可数名词，此处表泛指用复数，故填plants。
7. 动词help后接人称代词宾格，we的宾格是us，故填us。
8. 由now可知用现在进行时，主语scientists复数，故填are studying。
B. 1. 文章主题是恐龙研究，属于科学类内容，故选D。
2. 原文明确提到“Scientists study fossil footprints to see how fast dinosaurs move”，故选B。
【答案】
A. 1. are cleaning 2. are watching 3. about 4. slowly 5. swim 6. plants 7. us 8. are studying
