Ⅰ.阅读理解(每小题2.5分，共10分)
The world's oceans will likely lose about one-sixth of their fish and other creatures within 100 years if climate change continues at its present speed.These are the findings of a computer-based study by an International team of marine biologists (海洋生物学家).
Every degree Celsius (℃) that the world's oceans warm，their biomass，or the total weight of all the marine animal life，is expected to drop by 5%，the study also found.The study predicts that if there is no change in the speed of worldwide greenhouse gas production，there will be a 17% loss of biomass by the year 2100.But，if the world reduces carbon (碳) pollution，biomass losses could be limited to only about 5%.
William Chung is a marine biologist at the University of British Columbia in Canada.He co-wrote the study，and told the Associated Press，“There are already changes that have been noticed.”
Warming temperatures are the biggest problem.But climate change also produces oceans that are more acidic and have less oxygen，which can also harm sea life.
Much of the world depends on the oceans for food and work，the scientists say.University of Victoria biology professor Julia Baum was not part of the study，but she said the findings made sense.She noted that the possible influence of the predicted losses of animal life was huge.“Climate change may cause serious new problems with ocean resource (资源) use and food safety as the human population continues to grow，” said Baum.Marine biologist Boris Worm，who helped run the study，added that those marine animals that we used directly and cared about most deeply were predicted to be most affected.
Former computer-based studies looked at only part of the picture or used only one model.The latest study used six different computer models to give the best picture look，William Cheungn said.
[语篇解读]　本文是一篇说明文。文章主要讲述气候变化对海洋生物多样性的影响，特别是如果气候变化按照当前速度持续下去，海洋生物量将会显著减少。
1.Which of the following words can be used to describe the study

2.What can we know from the findings

B.The speed of worldwide greenhouse gas production is slowing.
C.The warmer the world's oceans are，the lower their biomass is.
D.The world's oceans will lose most of their creatures in 100 years.
解析　C　细节理解题。根据第二段“Every degree Celsius...drop by 5%”可知，海洋温度越高，其生物量越低。故选C。
3.What can we infer from William Cheung's words
A.The findings work as a call for action.
B.More fish that we usually eat will die in the future.
C.The latest study provided better picture than ever.
D.The new study is the first one to be carried out on computers.
解析　C　推理判断题。根据最后一段“The latest study...the best picture look”可知，最新的研究提供了比以往更好的画面效果。故选C。

Ⅱ.阅读七选五(每小题2.5分，共12.5分)
World Oceans Day
World Oceans Day on 8 June every year is a special day for learning about oceans，why they're in danger and how important it is to protect them.
There are five oceans on Earth：the Pacific Ocean，the Atlantic Ocean，the Indian Ocean，the Antarctic Ocean and the Arctic Ocean，of which the Pacific Ocean is the biggest and the Arctic Ocean is the smallest and is frozen for much of the year.____
2 Oceans are home to 50 to 80 percent of all species on Earth.Oceans hold about 97 percent of all the water on our planet and give us rainwater and drinking water through the water cycle.At least half the oxygen we breathe comes from the plants in the ocean.
1
3 A lot of our food comes from oceans，and millions of people worldwide have jobs related to fishing and fish farming.Oceans also provide us with much of our energy.We can also use the power of waves and tides to produce electricity and many wind farms are located offshore.
Sadly，our oceans are in danger.Billions and billions of pieces of plastic are floating around in our oceans.Plastic pollution is harming and killing sea creatures like fish，birds and turtles. 4 That's because fish eat the tiny pieces of plastic and then humans eat the fish.
For World Oceans Day you could join in many activities. 5 You could use social media platforms to share posts，photos or videos that show how important oceans are and why we need to protect them.You could take part in a photo，art or writing contest around the theme of the ocean or watch ocean-related films and documentaries.
A.You could do a beach clean-up.
B.Without oceans，life couldn't exist.
C.It's also dangerous for our health too.
D.Humans use the ocean in many different ways.
E.But it is melting now because of global warming.
F.Despite all its benefits，the ocean still needs support.
G.We should work together to create a new relationship with oceans.

2.B　根据下文可知，此处是在阐述海洋对生命存在的重要性，若没有海洋，生命就无法存在，B项符合语境，故选B。
3.D　下文是在讲人类从海洋中获取食物、能源等多方面利用海洋的情况，D项符合语境，故选D。
4.C　根据上下文可知，塑料污染不仅对海洋生物有害，对人类健康也是危险的，C项符合语境，故选C。
5.A　根据上文可知，后面要具体列举一些活动，A项是列举的活动之一，符合语境，故选A。
Ⅲ.语法填空(每小题1.5分，共15分)

[语篇解读]　本文是一篇说明文。文章介绍了新加坡在七个水下地点安装了42个“迷你酒店”，即自主珊瑚礁监测结构(ARMS)，旨在帮助科学家更好地了解海洋生物。
1.announced　考查非谓语动词。分析句子结构可知“(announce) on Oct 28”作后置定语，announce(宣布)是非谓语动词，与其逻辑主语a new research effort之间是动宾关系，用过去分词作后置定语，表被动。故填announced。
2.as　考查介词。be known as是固定短语，意为“被称为”。故填as。
3.providing　考查非谓语动词。“(provide) corners and cracks for...”作伴随状语，provide(提供)是非谓语动词，与逻辑主语the structures之间是主动关系，用动词-ing形式表主动。故填providing。
4.creatures　考查名词的单复数。可数名词creature作宾语，意为“生物”，结合语境，海洋生物不止一种，用复数形式表泛指。故填creatures。
5.diversity　考查名词。冠词a后接名词diversity；a diversity of是固定短语，意为“多种多样的”。故填diversity。
6.are　考查时态和主谓一致。be是谓语动词，根据语境，描述客观事实，用一般现在时，主语“the coral reef habitats”是复数名词，谓语动词用复数形式。故填are。
7.relatively　考查副词。设空处修饰形容词比较级more degraded，用副词relatively，意为“相对地”。故填relatively。
8.which/that　考查定语从句。“________ have been put in place”是限制性定语从句，修饰先行词“the forty-two ARMS”，指物，关系词在定语从句中作主语，应用关系代词which或that引导该从句。故填which/that。
9.the　考查冠词。the rest是固定短语，意为“其余的”。故填the。
10.and　考查连词。“collect the structures”和“take the plates apart”之间是并列关系，用连词and连接。故填and。
