【分析】
拿到这类根据句意补全单词的题目,首先第一步要通读完整句子,准确理解句子想要表达的核心含义,第二步结合平时积累的英语固定短语、连词和介词的用法,匹配空格处缺失的词汇,遇到句首的单词还要注意首字母大写,最后把填好的词代入句子通读,验证搭配是否正确、语义是否通顺,就能得出正确答案。
【解析】
1. 句意为:她起初不喜欢地理,但是渐渐地,她开始享受了解不同国家的相关知识。此处考查固定短语bit by bit,意为“一点一点地、逐渐地”,因此空格填by。
2. 句意为:水手们齐心协力把装满鱼的沉重渔网拉了上来。此处考查固定短语pull up,意为“拉起、拽上来”,符合水手收渔网的语境,因此空格填up。
3. 句意为:科学家首次在一颗和地球相似的行星上发现了水。此处考查固定短语for the first time,意为“第一次、首次”,作时间状语放在句首时首字母需要大写,因此空格填For。
4. 句意为:我们必须保护环境,否则我们的星球将会出问题。此处是“祈使句+or+陈述句”的典型结构,or表示“否则、要不然”,符合前后句的逻辑关系,因此空格填or。
5. 句意为:当我们在云层上方飞行时,从飞机窗户向外看的感觉棒极了。此处考查介词辨析,above表示“在……上方(两者不接触)”,符合飞机飞行在云层之上的语境,因此空格填above。
【答案】
1. by 2. up 3. For 4. or 5. above
【知识点】
固定介词短语,并列连词用法,介词辨析
【点评】
本题侧重考察初中阶段核心的基础短语和词汇用法,整体语境都贴合课本常见场景,学生只要平时做好课内固定搭配的积累,结合句子逻辑推导就能顺利完成,做完后代入句子通读检查可以避免搭配误用、大小写错误这类低级失误。

【分析】
做完形填空首先要先通读全文,把握文章核心主旨:本文讲述了作者跟随登山队在非洲乞力马扎罗山大本营度过的一段难忘的登山经历。解题时要遵循“上下文找线索+常识验证+词义辨析”的思路:第一步先通读了解故事脉络,第二步逐空结合前后文的提示信息、生活常识和词汇搭配逐一排除错误选项,第三步把所有答案代入全文通读,验证整体逻辑是否通顺,避免出现前后矛盾的情况。比如看到后文“呼吸困难”就能反推高海拔地区空气稀薄,看到“准备保暖衣物”就能反推夜晚气温会下降,这类前后呼应的线索是解题的核心依据。
【解析】
1. 乞力马扎罗山是非洲最高的山峰,符合地理常识,选B.highest。
2. 句意为“去年夏天我加入了一支登山队抵达大本营”,join表示加入某个团体/队伍,是固定搭配,选A.joined。
3. 全文都在描述这段经历充满惊喜与挑战,结尾也点明这是难忘的回忆,因此是度过了一个难忘的夜晚,选C.unforgettable。
4. 前文提到在大本营度过夜晚,此处对应表示“这是我第一次在高山上过夜”,at night是固定搭配,选D.night。
5. 向导提醒大家准备保暖衣物,说明夜晚气温会骤降,drop sharply表示气温骤降,选B.drop。
6. 得知夜晚气温会快速下降,我们快速搭好了帐篷,quickly符合语境逻辑,选B.quickly。
7. 后文提到“我们呼吸困难”,高海拔地区的特征就是空气稀薄,thin可以用来形容空气稀薄,选A.thin。
8. 句意为“虽然我们呼吸困难,但所有人对即将到来的夜晚都十分兴奋”,excited符合登山者的情绪,选C.excited。
9. 太阳落山之后,天空会逐渐变黑,符合自然常识,选B.dark。
10. 高海拔地区没有光污染,这里的星星比作者以往见过的更亮、数量更多,brighter符合语境,选C.brighter。
11. 句意为“没有城市的灯光去遮蔽星星,整片天空就像缀满无数钻石的黑布”,cover表示遮盖、遮蔽,符合语义,选A.cover。
12. 句意为“我躺在地上抬头仰望,在自然的美景前感觉自己十分渺小”,lie的过去式lay表示躺,符合动作逻辑,选B.lay。
13. 向导给我们讲了很多关于乞力马扎罗山的内容,包括它的历史和栖息在山上的动物,对应的是相关的故事,选A.stories。
14. 午夜开始起风,结合前文提示的夜晚气温骤降,此时天气会变得更冷,选C.colder。
15. 句意为“这是一段我永远不会忘记的经历”,forget符合全文表达的难忘的主旨,选A.forget。
