四、Fill in the blanks. 用所给单词的正确形式填空。
1. Look! The children ___ (play) in the snow.
2. Daming is ___ (help) his mum.
3. She likes ___ (swim) in the sea.
4. The bus is ___ (come) to the station.
5. It’s too hot. The sun ___ (shine) in the sky.

1. are playing 2. helping 3. swimming 4. coming 5. is shining

【分析】首先通过句中提示词或语境判断时态：1句有Look! 是现在进行时标志；2、4句含be动词is，需用现在进行时；3句是like的固定搭配；5句语境表现在进行时。再结合动词现在分词的变化规则（重读闭音节双写、不发音e结尾去e等）和be动词单复数变化完成填空。
【解析】1. 句首Look! 提示用现在进行时，结构为“am/is/are + 动词现在分词”，主语the children是复数，be动词用are，play的现在分词是playing，故填are playing。
2. 句中已有be动词is，需用现在进行时，help的现在分词直接加ing，故填helping。
3. 固定搭配like doing sth表示“喜欢做某事”，swim是重读闭音节动词，变现在分词需双写末尾辅音字母m再加ing，故填swimming。
4. 句中已有be动词is，需用现在进行时，come以不发音的e结尾，变现在分词需去e加ing，故填coming。
5. 语境“It’s too hot”表现在状态，用现在进行时，主语the sun是单数，be动词用is，shine的现在分词是shining，故填is shining。
【答案】1. are playing 2. helping 3. swimming 4. coming 5. is shining
【知识点】现在进行时；动词现在分词变化；like的固定搭配
【点评】本题考查英语基础时态（现在进行时）及相关固定搭配，需掌握现在进行时的结构、动词现在分词的变化规则，属于常规基础题型。
