解析

【分析】
拿到这篇语法填空,首先先通读全文,了解文章是介绍水肺潜水以及深海世界相关的科普内容,把握整体语境和行文逻辑。接下来逐个分析空格:
1. 空格1后是名词短语undersea world,修饰名词需要用形容词,因此要把名词wonder转换为对应的形容词形式。
2. 空格2描述潜水过程中将会发生的动作,符合一般将来时的使用场景。
3. 空格3前是形容词sharp,此处泛指海洋生物的锋利牙齿,可数名词tooth表泛指一类事物需要用复数形式。
4. 空格4后接the day,要表达“在白天”的含义,用介词构成固定搭配即可。
5. 空格5后是完整的分句fish swim nearby,和后面的主句构成时间逻辑关系,需要用时间状语从句的引导连词。
6. 空格6后是可数名词单数easy place,表达“一个适合生存的地方”,根据单词开头的音素选择对应的不定冠词。
7. 空格7符合“the + 比较级,the + 比较级”的经典固定结构,需要写出little对应的比较级形式。
8. 空格8指代继寒冷、黑暗之后的第三个危险,需要把基数词three转换为对应的序数词。
9. 空格9表示在所有海洋动物中最可怕的是鲨鱼,多者之间的顶级比较要使用形容词最高级。
10. 空格10后是名词meal,要表达“其他动物的食物”的所属含义,需要使用复数名词的所有格形式。
【解析】
1. 空格1:修饰名词undersea world需要形容词,名词wonder的形容词变形为wonderful,意为“绝妙的”,符合语境。
2. 空格2:此处描述潜水时将会发生的动作,用一般将来时结构will+动词原形,因此填will find。
3. 空格3:tooth是可数名词,此处泛指锋利的牙齿,不规则复数变形为teeth。
4. 空格4:固定搭配during the day意为“在白天”,句首首字母大写,因此填During。
5. 空格5:引导时间状语从句,表达“当鱼在附近游动时”,连词when符合逻辑,句首首字母大写,因此填When。
6. 空格6:此处表示泛指“一个容易生存的地方”,easy以元音音素开头,不定冠词用an。
7. 空格7:固定结构the + 比较级,the + 比较级意为“越……就越……”,little的比较级为less。
8. 空格8:此处表示第三个危险,基数词three对应的序数词third表示“第三”,符合语境。
9. 空格9:此处表示所有海洋动物里最可怕的是鲨鱼,多音节形容词terrible的最高级为the most terrible。
10. 空格10:此处表示“其他动物的食物”,复数名词animals的所有格直接在s后加',变形为animals',修饰后面的名词meal。
【答案】
1. wonderful
2. will find
3. teeth
4. During
5. When
6. an
7. less
8. third
9. the most terrible
10. animals'
【知识点】
词性转换;形容词比较级最高级;名词所有格
【点评】
本题是科普类短文语法填空,考点覆盖初中英语核心基础语法点,大部分空可以通过固定搭配、词性修饰规则直接推导,少数需要结合语境判断时态和比较级最高级的使用,整体侧重考查学生对基础语法规则的灵活运用能力,易错点集中在不规则名词复数、复数名词所有格和多音节形容词最高级的变形上。
