2. 解析:“water”表示“水”时是不可数名词,不可加“s”,也不能直接用不定冠词“a”修饰;“some water”虽语法正确,但题干强调植物生长需要水这一基础需求,用“water”更简洁符合基础用法,故选A。
3. 解析:句中“now”是现在进行时的标志性时间状语,现在进行时结构为“主语 + be动词 + 动词-ing形式”,主语“my father”是第三人称单数,be动词用“is”,“clean”的-ing形式为“cleaning”,故选D。

10. 解析:“be important to sb.”是固定搭配,意为“对某人来说很重要”,强调某物对某人的重要性;“be important for sb. to do sth.”是常用延伸结构,此处题干无不定式,故用“to”,故选B。六、用所给词的正确形式填空。(每小题2分,共10分)
1. are digging 2. planting 3. grows 4. water 5. leaves
【解析】
1. 解析:句中“Look!”是现在进行时的标志词,提示动作正在发生,现在进行时结构为“be动词 + 动词-ing形式”,主语“They”是复数,be动词用“are”,“dig”的-ing形式为“digging”,故填“are digging”。
2. 解析:“like doing sth.”是固定搭配,意为“喜欢做某事”,强调长期的、习惯性的喜好,“plant”的-ing形式为“planting”,故填“planting”。
3. 解析:主语“the rice”是不可数名词,视为第三人称单数,题干描述的是客观事实,用一般现在时,动词“grow”需加“s”变为第三人称单数形式“grows”,故填“grows”。
4. 解析:句中“every morning”是一般现在时的标志性时间状语,提示动作是经常性、习惯性的,主语“We”是复数,谓语动词用原形,故填“water”。
