Ⅰ．【语篇解读】 本文是一篇说明文。文章主要介绍了观察大猩猩用植物治疗伤口的相关研究以及发现。
1．A [推理判断题。根据第二段“These animals are known to be among the most intelligent non human primates...They can even use Skype with some help from humans．”可知，作者在第二段提到Skype是为了支持“大猩猩被认为是最聪明的非人类灵长类动物之一”这一个想法。]
2．B [段落大意题。根据第四段“The researchers noted in June that Rakus had a small wound on his face following a fight with another mature male orangutan...．He chewed them and then applied the resulting paste to his facial wound．”可知，第四段的主要内容是拉库斯如何处理他的伤口。]
3．D [推理判断题。根据最后一段中“The researchers assumed that early humans may have learned about certain treatments by observing animals engaging in similar behaviors...Increasingly，it looks like orangutans are one cave painting away from civilization．”可知，新的观察结果增加了证明猩猩智力的证据。]
4．D [标题归纳题。根据第一段中“A new observation in Sumatra caught seasoned scientists by surprise...This leaves scientists wondering: Did humans invent medicine，or does it pre date our species？”，结合文章主要介绍了观察大猩猩用植物治疗伤口的相关研究以及发现，可知，D选项“观察到一只猩猩将药用植物涂抹在伤口上”最适合作为文章标题。]
【语篇解读】 本文是一篇说明文。文章主要围绕大黄蜂种群数量下降的问题展开，解释了这一现象可能的原因——全球变暖导致的温度升高。文章通过引用研究数据、专家观点等，对大黄蜂的生态重要性、适应温度范围，以及高温对其种群的影响进行了说明。
5．B [细节理解题。根据文章第一段中“Bumblebee populations have declined by 90 percent in the past 20 years．The decline of the bumblebees is highly concerning as they are significant for ecosystems．”可知，大黄蜂的数量在过去的二十年里大幅度减少。]
6．D [细节理解题。根据文章第三段中“Kevan and his colleagues decided to take a closer look at the facts relating to bumblebee populations across the world...but the perfect temperature for nests is between 28 to 32 degrees Celsius．”可知，Kevan和他的同事们查阅了180年来关于这个物种的文献，这说明他们是通过研究关于大黄蜂的文献来进行研究的。]
7．B [推理判断题。根据文章最后一段“Although the studies led by Kevan have limitations，the potential effects for bumblebee health and conversation are large and long term．”可知，作者对Kevan的研究持支持态度。]
8．D [标题归纳题。根据文章第二段“And now，a new study published in the Frontiers in Bee Science has found that...Peter Kevan of the University of Guelph in Canada and lead author of the study said in a statement．”以及全文内容可知，文章主要围绕大黄蜂种群数量下降的问题展开，通过引用研究数据、专家观点等，解释了这一现象可能的原因——全球变暖导致的温度升高。选项D准确概括了文章的主题。]
Ⅱ．【语篇解读】 本文是一篇说明文。文章主要介绍了安全遛狗的小贴士。
1．B [根据前文“Having a dog is good for your health．”以及后文“You need to organize your day well and adjust it for your dog's daily walking needs．”可知，这两句话之间需要一个过渡句，说明养狗虽然对健康有好处，但也有一定的付出，特别是时间上的付出。因此，B项符合语境。]
2．A [根据后文“Of course，the situation may happen when you badly need to go，for example，to a shop and then you have to leave the dog on a leash．But you must not often leave the animal like this because you endanger its life．And the dog can be a danger to people on the street．”可知，本段主要讲述了遛狗时不要单独把狗留下，所以A选项符合语境。]
3．C [根据前文“Pick less visited places．When choosing a place for walking with a dog，you had better pick less visited squares and parks，and other less popular areas where there are only a small number of people．”可知，空处应对此进行解释说明，说明这些地方是安全的，适合狗狗玩耍。因此，C项符合语境。]
4．D [根据前文“Take the best number of walks in a day for your dog．Though even just one walk every day may be enough for smaller dogs，high energy dogs will need more than that．”以及后文“The question of how much time to walk is also important．The best choice is to prepare at least 40 minutes for a walk with your dog．”可知，此空应承接上文，说明需要了解狗的能量水平，来合理安排遛狗次数。因此，D项“所以你需要了解你的狗，了解它的能量水平”符合语境。]
5．F [根据前文“Take your dog to meetups．Dogs enjoy meetups with other dogs．Plan dog meetups and group walks for your dog to play with other dogs．Walking in a group means you get to share experiences with other dog owners as well．”以及后文“So take your dog out to meet up with other dogs．It is good for their health．”可知，此空应说明狗狗聚会的好处，所以F项符合语境。]

Ⅰ．阅读理解(共8小题；每小题2．5分，满分20分)
A
A new observation in Sumatra caught seasoned scientists by surprise．An orangutan(红毛猩猩) known as Rakus treated a fresh wound with a medicinal plant，making this the first time an animal has been seen applying a biologically active substance(物质) for its health benefits．This leaves scientists wondering: Did humans invent medicine，or does it pre date our species
These animals are known to be among the most intelligent non human primates(灵长类)．They've been observed using tools，communicating vocally，and engaging in even more complex behaviors like calculated reciprocity，which involves aiding another orangutan with the expectation of being paid back．They can even use Skype with some help from humans．
Roughly 60，000－70，000 of these creatures remain in the wild，about 15，000 of which live on the Indonesian island of Sumatra．That's where the Suaq Project，part of the Max Planck Institute for Animal Behavior，observes orangutans in their natural habitat．
The researchers noted in June that Rakus had a small wound on his face following a fight with another mature male orangutan．Several days later，Rakus did something no one had ever seen a primate do before．He began carefully picking the leaves from a climbing vine(藤蔓) known as akar kuning．Local human populations have long used these leaves for pain relief and to treat conditions like malaria．Orangutans don't usually eat these plants; indeed，Rakus didn't eat them．He chewed(嚼碎) them and then applied the resulting paste to his facial wound．
This is the first time researchers have seen such behavior in 21 years at the Sumatran research station．Wild orangutans are rarely injured，so this may be a rare but widespread behavior．Or perhaps Rakus is the only one that knows this trick．The researchers assumed that early humans may have learned about certain treatments by observing animals engaging in similar behaviors．And here we are，thousands of generations later，still watching and wondering just how smart they are．Increasingly，it looks like orangutans are one cave painting away from civilization．
1．Why does the author mention Skype in paragraph 2
A．To support an idea．
B．To draw a conclusion．
C．To explain a problem．
D．To present a suggestion．
2．What is paragraph 4 mainly about
A．How Rakus got injured．
B．How Rakus treated his wound．
C．What Rakus ate in the wild．
D．What Rakus explored in the forest．
3．What can be inferred about the new observation
A．It proves the medical value of a plant leaf．
B．It shows a widespread behavior among orangutans．
C．It answers one of scientists' questions about medicine．
D．It adds evidence to show the intelligence of orangutans．
4．Which of the following is a suitable title for the text
A．Non human Primates Seen Using Tools in the Wild
B．Orangutans Proved to Be the Most Intelligent Primate
C．A Project Observes Orangutans in Their Natural Habitat
D．An Orangutan Observed Applying Medicinal Plants to a Wound

Bumblebee(大黄蜂) populations have declined(下降) by 90 percent in the past 20 years．The decline of the bumblebees is highly concerning as they are significant for ecosystems．They pollinate(授粉) flowers and crops．If their populations were to continue to decline，crops would not be able to produce fruits and vegetables．Despite being small，they are important to nature's balance．
And now，a new study published in the Frontiers in Bee Science has found that the rising heat caused by global warming might be a reason for the decrease in numbers across the globe．“The decline in populations and ranges of several species of bumblebees may be explained by issues of overheating of the nests，” Peter Kevan of the University of Guelph in Canada and lead author of the study said in a statement．
Kevan and his colleagues decided to take a closer look at the facts relating to bumblebee populations across the world．Kevan and his colleagues looked at 180 years of literature on the species and found one common reason across all bumblebee species that they can survive in temperatures up to 36 degrees Celsius，but the perfect temperature for nests is between 28 to 32 degrees Celsius．They are unlikely to be able to adjust themselves to the extent that rising temperatures due to climate change require，the study reports．While individual bees may be able to deal with increased heat better than others，the study notes that if nests are too hot，the groups will not survive．
“The effect of high nest temperatures has not been studied very much，which is surprising，” Kevan said．Similar studies have been done on honeybees(蜜蜂)，another threatened yet highly important species．This suggests further that heat stress is a major factor in bees' overall decline．
Although the studies led by Kevan have limitations，the potential effects for bumblebee health and conversation are large and long term．
5．What do we know about bumblebees from paragraph 1
A．They have been extinct within decades in America．
B．Their populations have decreased a lot in the last two decades．
C．Americans are concerned about their living environment．
D．They tend to depend on flowers and crops to survive．
6．How did Kevan and his coworkers carry out the study
A．They raised bumblebees to observe them．
B．They focused on studying individual bumblebees．
C．They conducted experiments on bumblebees．
D．They studied literature on bumblebees．
7．What is the author's attitude toward Kevan's studies
A．Unclear． B．Supportive．
C．Doubtful． D．Uninterested．
8．Which can be a suitable title for the text
A．Big Results for Small Bumblebees
B．Bumblebees Protection Inspires Scientists
C．The Impact of Climate Change on Honeybees
D．Research Shows the Main Reason of Bumblebee Decline
