Ⅱ.语法填空
Today, much of the world's ocean is still a mystery. Only 5 percent of it 1 (explore) so far. In fact, we know more about some areas of Mars 2 some parts of the world's ocean.
New technology, however, is helping scientists explore these 3 (hide) worlds. For example, scientists are using an underwater vehicle called DeepSee to explore seamounts — underwater mountains. Scientists have used DeepSee to study Las Gemelas, an area of seamounts near Costa Rica. A huge variety 4 species live around Las Gemelas. Some of these species may have chemicals 5 can help people fight illnesses.
The 6 (deep) location of the earth is the Mariana Trench in the Pacific Ocean. The ocean floor there is about 11,000 meters deep. In 2012, a filmmaker and explorer 7 (reach) the Mariana Trench in a vehicle called Deepsea Challenger. He was the first 8 (complete) the journey alone. Cameron took 9 (photo) and made videos on the ocean floor. Deep-sea exploration also helps us in other ways. For example, we are learning how underwater earthquakes cause tsunamis (海啸)．As the filmmaker says, “This is the beginning of 10 (open) up a new frontier.”
语篇解读：本文是一篇说明文。文章主要讲的是世界上的大部分海洋仍然是个谜，但新技术正在帮助科学家探索这些隐藏的世界。
1．has been explored　考查动词的时态、语态和主谓一致。由so far可知，句子时态用现在完成时；世界上的海洋是被开发，因此空格处是现在完成时的被动语态，又因主语5 percent of it是单数，故填has been explored。
2．than　考查介词。由前面的more是比较级可知，空格处用表示比较的介词than。
3．hidden　考查形容词。空格处用形容词作定语，根据句意可知，空格处表示“隐藏的”，故填hidden。
4．of　考查介词。a variety of是固定短语，意为“各种各样的”。
5．that/which　考查定语从句。分析句子结构可知，空格处引导定语从句，从句中缺少主语，先行词chemicals指物，故填that/which。
6．deepest　考查形容词最高级。此处表示最深的位置，the后跟形容词的最高级，故填deepest。
7．reached　考查时态。由In 2012可知，句子描述过去的动作，句子时态用一般过去时。
8．to complete　考查非谓语动词。the first后用动词不定式作后置定语。
9．photos　考查名词复数。photo是可数名词，前面无冠词，因此空格处用复数。
10．opening　考查非谓语动词。of为介词，其后跟动名词作宾语。3 / 4

Ⅰ.完形填空
语篇解读：本文是一篇说明文。文章介绍了从古至今人们是如何了解世界的。
1．选A　根据下文“what this curious phrase means”可知，对于这一奇怪的短语，人们或许会想知道(wondered)其表达的意思。
2．选B　根据前文“If you can see the trees”可知，作者意在表明看见和看不见之间的逻辑关系。visible“可见的”。
3．选D　根据前文“If you can see the trees, how is the forest not ________， too？”可知，人们会只注意细节(details)而忽略整体大局。下文中“interesting details”也是提示。
4．选C　根据前文“This popular phrase ... big picture.”可知，空后与上句的意思一致，所以作者是换句话表达。in other words“换句话说”。
5．选D　根据空后“from time to time”和常识可知，“只见树木不见森林”这一问题我们经常遇到。meet with“遇到”。
6．选B　根据语境可知，此处指我们很容易注重小细节而忽视(ignore)整体大局。
7．选C　根据下文中“Since the beginning of scientific inquiry thousands of years ago, observations have been ________.”可知，对于科学家来说，既关注森林又关注树木是很重要的。
8．选D　根据下文“The first scientists used their ________ to see, hear, smell, feel, and taste the world around them.”可知，早期科学家们通过感官去观察世界，这说明观察一直很重要(important)。
9．选A　根据空后“see, hear, smell, feel, and taste”可知，这些均为人的感官(senses)。
10．选C　根据上文“Since the beginning of ... around them.”可知，通过观察来了解世界。observation“观察”为原词复现。
11．选B　根据空前的“they learned about their world and began to search for answers to the questions”可知，科学家们通过这些观察了解世界，并探索在这个过程中自然产生的问题的答案。naturally“自然地”。
12．选D　根据前一段可知，现在的科学家依然(still)依赖五种感官进行观察。
13．选B　根据空前的“However, they also take advantages of ... tools.”可知，现代技术和工具的使用让科学家们能够通过五种感官之外的方式“看”世界。
14．选A　根据空前的“From satellite telescopes to atomic microscopes”可知，从卫星望远镜到原子显微镜，现代科学家所使用的这些工具是早期科学家从未想象(imagined)过的。
15．选C　根据前文“This popular phrase ...big picture.”可知，有些工具则能帮助科学家们看到整体。此处the big picture指“整体”，不仅看见树木，还能看见森林。上文中的“the big picture”已有提示。
Ⅱ.语法填空
语篇解读：本文是一篇说明文。文章主要讲的是世界上的大部分海洋仍然是个谜，但新技术正在帮助科学家探索这些隐藏的世界。
1．has been explored　考查动词的时态、语态和主谓一致。由so far可知，句子时态用现在完成时；世界上的海洋是被开发，因此空格处是现在完成时的被动语态，又因主语5 percent of it是单数，故填has been explored。
2．than　考查介词。由前面的more是比较级可知，空格处用表示比较的介词than。
3．hidden　考查形容词。空格处用形容词作定语，根据句意可知，空格处表示“隐藏的”，故填hidden。
4．of　考查介词。a variety of是固定短语，意为“各种各样的”。
5．that/which　考查定语从句。分析句子结构可知，空格处引导定语从句，从句中缺少主语，先行词chemicals指物，故填that/which。
6．deepest　考查形容词最高级。此处表示最深的位置，the后跟形容词的最高级，故填deepest。
7．reached　考查时态。由In 2012可知，句子描述过去的动作，句子时态用一般过去时。
8．to complete　考查非谓语动词。the first后用动词不定式作后置定语。
9．photos　考查名词复数。photo是可数名词，前面无冠词，因此空格处用复数。
10．opening　考查非谓语动词。of为介词，其后跟动名词作宾语。
