【文章大意】这是一篇说明文。世界上的大部分海洋仍然是个谜, 然而, 新技术正在帮助科学家探索这些隐藏的世界。文章介绍了一位科学家对地球上最深的地方——太平洋的马里亚纳海沟的探索。
1. 【解析】has been explred。考查现在完成时态的被动语态和主谓一致。句意: 到目前为止, 只有百分之五的地方被探索过。句子主语是Only 5 percent f it, 第三人称单数, 和谓语动词explre之间是被动关系, 再根据s far“到目前为止”, 可知句子用现在完成时态的被动语态。故填has been explred。2. 【解析】than。考查连词。句意: 事实上, 我们对火星某些地区的了解要比对海洋某些地区的了解还要多。根据mre可知此处是比较级。故填than。
3. 【解析】hidden。考查过去分词。句意: 然而, 新技术正在帮助科学家探索这些隐藏的世界。此处wrlds和hide之间是被动关系, 故用过去分词作前置定语。故填hidden。4. 【解析】an。考查不定冠词。句意: 例如, 科学家正在使用一种名为“深海”的水下工具来探索海底山——水下山脉。此处underwater以元音音素开头, 前面加an表示“一种水下的工具”。故填an。
5. 【解析】variety。考查固定词组。句意: Las Gemelas周围生活着各种各样的物种。固定词组: a variety f“各种各样的”。6. 【解析】that/which。考查定语从句。句意: 其中一些物种可能含有可以帮助人们对抗疾病的化学物质。此处chemicals是先行词, 指物, 放在后面的定语从句中作主语, 所以由that/which来引导定语从句。故填that/which。
7. 【解析】deepest。考查形容词最高级。句意: 地球上最深的地方是太平洋的马里亚纳海沟。马里亚纳海沟是地球上“最深的”地方, 所以这里用形容词最高级。故填deepest。8. 【解析】t cmplete。考查动词不定式作后置定语。句意: 他是第一个独自完成旅程的人。固定用法: the first (secnd. . . )t d sth. “做某事的第一个(二个……)”。此处是动词不定式作后置定语。故填t cmplete。
9. 【解析】phts。考查名词复数。句意: 卡梅隆在海底拍摄照片和录像。固定搭配: take phts“拍照”。此处用名词复数。故填phts。10. 【解析】beginning。考查名词。句意: 这是开拓新疆域的开始。分析句子结构可知the用在名词前面。故填beginning。
Ⅳ. 微写作(2021·曲阜高二检测) 假设你是红星中学高三学生李华。你的美国朋友Jim得知你对探月感兴趣, 发来邮件和你讨论该话题。请你给他回复邮件, 内容包括: 1. 月亮在中国文化中的寓意; 2. 你对人类探月活动的看法。 注意: 1. 词数80左右; 2. 开头和结尾已给出, 不计入总词数。
Dear Jim, 　　I am glad t share with yu mre details abut my passin fr mn explratin. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Yurs, Li Hua
【参考范文】Dear Jim, I am glad t share with yu mre details abut my passin fr mn explratin. It started with what I had been tld abut the mn as a kid and grew strnger with time. As yu can guess, there is rich cultural meaning behind the faithful cmpanin f the earth. In Chinese culture, as ppsed t the masculinity f the sun, the mn is ften cmpared t a quiet and elegant lady. Als, it reminds peple f their family and friends far away. Peple feel reassured knwing that they are watching the same mn as if the mn culd serve as their messenger.
Human beings have never stpped explring ur clsest neighbr. I believe it is f great significance. The develpment f relevant technlgy facilitates the prgress f science in general, which benefits ur everyday life. What’s mre, I think mn explratin shws an imprtant human trait, that is, curisity abut the unknwn, which is the driving frce that has brught ur species this far.
