解析

【分析】
这是英语选词适当形式填空题,解题思路如下:第一步先通读全文,把握文章介绍雨林作用、现状及保护措施的核心主旨,同时先明确方框内5个词/短语的词义和基本属性。第二步逐空结合上下文语义、语法搭配判断所需词汇:1空要表达雨林和动植物的所属栖息关系,对应短语be home to,结合主语和时态变形;2空和“吸收二氧化碳”并列,对应“产出氧气”的动作,用原形即可;3空主语是单数,并列谓语要和前面的三单形式保持一致;4空修饰动词work,需要把形容词变为副词;5空和名词knowledge并列作主语,要把动词educate变为名词形式,最后代入所有答案通读验证语义通顺即可。
【解析】
1. 句意:雨林覆盖约6%的地球表面,但它们是世界上超过一半动植物的栖息地。主语they指代复数的rainforests,描述客观事实用一般现在时,短语be home to表示“是……的栖息地”,be动词搭配are,因此填are home to。
2. 句意:雨林吸收二氧化碳,产出氧气,因此被称为“地球之肺”。and并列两个谓语,前面的take in为动词原形,主语rainforests是复数,直接用动词原形produce表示“生产、产出”,因此填produce。
3. 句意:这不仅让很多动物无家可归,还破坏了生态系统的平衡。主语This是单数,句子为一般现在时,谓语动词要使用第三人称单数形式,damage的三单变形为damages,因此填damages。
4. 句意:我们可以种植更多树木,和环保组织紧密合作。空格处修饰动词work,需要使用副词,形容词close的副词形式是closely,表示“紧密地”,因此填closely。
5. 句意:教育和知识同样是帮助保护雨林安全的有用工具。空格处和名词knowledge并列作主语,需要把动词educate变为名词形式Education,位于句首首字母大写,因此填Education。
【答案】
1. are home to 2. produce 3. damages 4. closely 5. Education
【知识点】
选词填空,词性转换,一般现在时
【点评】
本题难度适中,既考查学生对上下文语境的理解能力,也覆盖了动词时态变形、形容词副词转换、动词名词转换等基础语法点,解题时要注意结合并列结构的语法一致性判断词形,做完后代入通读可以快速排查错误。

答案

C. [文章大意]本文主要介绍了南极洲的地理环境,包括温度、降水、食物、光照以及特殊的自然现象等。
1. covers [解析]句意:冰几乎覆盖了整个大陆。根据句意可知,时态为一般现在时,主语为"Ice",所以谓语动词要用第三人称单数形式。cover意为"覆盖",符合语境。故填covers。
2. temperature [解析]句意:那里有记录以来的最低温度是零下89摄氏度!根据"was -89℃"可知,这里说的是最低温度。temperature意为"温度",符合语境。故填temperature。
3. all year round [解析]句意:它也是七大洲中最干燥的洲,因为全年降雨量极少。all year round意为"全年",符合语境。故填all year round。
4. thousands of [解析]句意:数千年来没有人在南极洲生活过。thousands of意为"成千上万的",符合语境。故填thousands of。
表示"数百"或"数千"等模糊数量时,用hundreds of或thousands of,后接可数名词复数;表示确切数量时,hundred或thousand用单数形式,前面用基数词,如two hundred students。
5. However [解析]句意:然而,如今人们探索和研究这片大陆也是有可能的。前文说南极洲条件恶劣没有人生活过,后文说现在人们可以去南极洲进行探索和研究,前后句是转折关系。however意为"然而",符合语境,且位于句首,首字母大写。故填However。
6. Scientists [解析]句意:来自世界各地的科学家都前往那里。根据"it is possible for people to explore(探索)and study the continent"并结合所给词可知,此处用名词复数scientists,且位于句首,首字母大写。故填Scientists。
7. longer [解析]句意:很少有人能停留超过六个月。"than"是比较级的标志,此处指很少有人停留超过六个月,long的比较级是longer,表示"更长时间的"。故填longer。
8. rises [解析]句意:那里一年只有一次日出和日落。rise意为"升起",主语"The sun"是第三人称单数,时态为一般现在时,所以谓语动词用第三人称单数形式rises。故填rises。
知识拓展 rise和raise辨析
rise为不及物动词,过去式为rose,表示太阳、物价等自身上升。例句:The sun rises in the east every morning. 每天早晨太阳从东方升起。
raise为及物动词,过去式为raised,表示举起、提高某物,后必须接宾语。例句:Please raise your hand if you have any questions. 如果有问题,请举手。
9. daylight [解析]句意:那意味着有六个月的白昼,然后是六个月的黑夜。那里一年中只有一次日出和日落,意味着有六个月的白昼和六个月的黑夜。daylight意为"日光",符合语境。故填daylight。
10. During [解析]句意:在冬季,那里没有太阳,仅靠一堆火和羊毛袜远不足以保暖。during表示"在……期间",during the winter表示"在冬天期间",符合语境,且位于句首,首字母大写。故填During。
