【分析】
这是一道英语语篇填空题,需结合语境、语法规则、固定搭配及词性转换解题。具体思路为:先分析每个空的语法功能(如修饰名词、作宾语等),再结合固定结构、短语搭配、词性变化及逻辑关系确定答案,比如“one of”后接名词复数、形容词修饰名词、固定搭配中的非谓语形式等。
【解析】
6. 考查名词复数。“one of + 形容词最高级 + 可数名词复数”是固定结构,意为“……之一”,故填wonders。
7. 考查形容词。此处需用形容词修饰名词weather,change的形容词形式为changeable,意为“多变的”,故填changeable。
8. 考查形容词。此处需用形容词修饰名词side,north的形容词形式为northern,意为“北方的”,故填northern。
9. 考查固定搭配。be determined to do sth是固定短语,意为“决心做某事”,故填to make。
10. 考查介词。此处表示“在海平面之上”,用介词above,故填above。
11. 考查反身代词。pull oneself up是固定短语,意为“向上爬”,主语为climbers,对应反身代词themselves,故填themselves。
12. 考查比较级。much用于修饰形容词/副词比较级,fast的比较级为faster,故填faster。
13. 考查名词。形容词性物主代词its后需接名词,high的名词形式为height,意为“高度”,故填height。
14. 考查非谓语动词。succeed in doing sth是固定搭配,意为“成功做某事”,故填reaching。
15. 考查连词。前后句为因果关系,前因后果,用连词so连接,故填so。
【答案】
6. wonders 7. changeable 8. northern 9. to make 10. above 11. themselves 12. faster 13. height 14. reaching 15. so
【知识点】
名词复数、词性转换、固定搭配
