To adapt to climate change, some flowers are darkening their color to protect themselves from the suns radiation, new research shows.
The study suggests that over the past 75 years, the ultraviolet (UV) pigments (紫外线色素) in flowers have increased in response to rising temperatures and the thinning ozone layer (臭氧层). The flowers won’t look any different to humans, but insects consider the higher levels of UV pigments as a darker color, which could be confusing when they try to find out colorful flowers to land on.
The UV-absorbing pigments in flowers work like sunscreen and protect sensitive cells from harmful radiation, Matthew Koski, a plant ecologist at Clemson University, says. He and his team hoped to determine if changes in pigments were a result of environmental change-and if so, what are the plants responding to The team collected dried, pressed plants across North America, Australia and Europe. In total, they studied 1, 238 samples from 42 different species dating back to 1941. Then, using a UV-sensitive camera, they photographed flower petals from each species. Next, they paired the photographs with the historic local temperature and ozone level data from the time the plant was picked to see how the pigment level changed over time.
The researchers found that the changes in pigments differ between species, a result of the flowers structure. Flowers with open, exposed pollen had more UV-absorbing pigments when ozone levels were low and radiation was high. But flowers with pollen surrounded by the petal responded to temperatures, not ozone levels.
As climate change continues to intensify, these changes in flowers color can affect plant-insect interactions. When the whole flowers get darker, insects might miss the flowers entirely. “This has a negative influence on plant reproduction,” Koski says.
11.What is the cause of flowers color changing according to the research
A. The impact of the climate crisis. B. The loss of natural habitats.
C. The harm of nuclear radiation. D. The thickening of the ozone layer.
12.How did Koski’s team get their findings
A. By collecting photographs of flowers from different species.
B. By analyzing how levels of UV pigments change over time.
C. By collecting abundant samples from various species.
D. By analyzing historic local temperature and ozone level data.
13.What can we learn about the change in pigments
A. It exists in flowers with exposed pollen only.
B. It responds to temperatures and sea levels.
C. It remains the same regardless of species.
D. It varies depending on the flowers structure.
14.What is Koski’s attitude toward the change in flowers color
A. Concerned. B. Indifferent. C. Unclear. D. Optimistic.

Advice on Choosing Your Career
You probably are very much concerned about which direction you take in your career, but before working through the process of generating and refining specific career choices, helicopter up to 10,000 feet from where you can view your overall career map, answer the big questions and set your overall direction. ①_________ What is your aim How long have you got Remember that there are no right answers, only the best choice for you, based on what you know now.
Having laid out your overall map, set boundaries and defined your personal targets, you can then turn to practical issues. ②_________ Write down examples of how you demonstrate key employability skills such as team work, leadership, and communication.
③_________ Go out and meet people, attend talks, go to relevant lectures, watch videos about industries and organizations, seek out websites that can give you objective and general career advice, for example, the open access Oxford university careers website.
Over time you can start to narrow down your choices and then choose one. ④_________
In 1804, Meriwether Lewis and William Clark set off with a compass and direction, and a general destination of mapping the new Louisiana territories in America. But they had no exact map. ⑤_________ Your career will be much longer but, like Lewis and Clark, it is about direction, not destination.
A. Where, roughly, are you going
B. Their successful expedition took two years.

答案以及解析
基础练习
1.答案：on
解析：“lay emphasis on” 是固定短语，意为 “强调；重视”，符合此处表达他们对儿童社区图书馆建设重视的语境，所以填 “on”。
2.答案：the
解析：“the instant” 是固定搭配，相当于连词 “as soon as”，引导时间状语从句，表示 “一…… 就……”，符合语境，所以填 “the”。
3.答案：had fled
解析：根据时间状语 “by October, 19...”(到 19…… 年 10 月为止)，句子应用过去完成时，其结构为 “had + 过去分词”，“flee” 的过去分词是 “fled”，所以填 “had fled”。
4.答案：which
解析：此处考查非限定性定语从句，先行词是 “The conclusion”，关系代词 “which” 在从句中作主语，指代先行词来进一步说明这个结论的相关情况，所以填 “which”。
5.答案：challenging
解析：考查形容词，句意:学习一门新语言可能很有挑战性，但它也是拓宽视野的好方法。
6.答案：extremely
解析：考查副词,句意:冯林非常荣幸地参加了中国共产党成立100周年纪念活动。修饰形容词honored,用副词形式。根据句意,故填extremely。
7.答案：reforming
解析：be committed to 是固定短语，意为 “致力于；专心于”，其中 to 是介词，后面接名词、代词或动名词作宾语。reform 作动词时，意为 “改革；改良”，这里用其动名词形式 reforming，表示 “这位在势均力敌的选举中获胜的总统致力于改革医疗保健制度”。
8.答案：have been destroyed
解析：根据时间状语 so far(到目前为止)可知，句子要用现在完成时，主语 half of woodlands and forests 和动词 destroy 之间是被动关系，即 “林地和森林被破坏”，所以要用现在完成时的被动语态，其结构为 have/has been + 过去分词，主语是复数，所以填 have been destroyed。
9.答案：Consisting
解析：这里考查非谓语动词作状语。句子的主语 the team 和动词 consist 之间是主动关系，即 “团队由…… 组成”，完整形式应该是 The team consists of the leading experts in the AI field，所以这里用现在分词 Consisting 作状语，表示原因。
10.答案：more energetic
解析：“while” 表对比，前句说年长员工更有经验，后句说年轻员工特点。“are” 后需形容词作表语，“energy” 是名词，其形容词 “energetic”(精力充沛的)符合描述年轻员工特点，又因对比有比较含义，所以用比较级 “more energetic”，表示更精力充沛。
思维拓展
1. 阅读理解
11.答案：A
解析：细节理解题。根据第二段“The study suggests that over the past 75 years, the ultraviolet (UV) pigments (紫外线色素) in flowers have increased in response to rising temperatures and the thinning ozone layer (臭氧层).(研究表明，在过去的75年里，由于气温上升和臭氧层变薄，花朵中的紫外线色素增加了)”可知，花朵中的紫外线(UV)色素随着温度升高和臭氧层变薄而增加，这是花朵应对气候变化的策略，故选A。
12.答案：B
解析：细节理解题。根据第三段“Next, they paired the photographs with the historic local temperature and ozone level data from the time the plant was picked to see how the pigment level changed over time.(接下来，他们将这些照片与采摘植物时当地的历史温度和臭氧水平数据配对，看看色素水平是如何随时间变化的)”可知，科斯基的团队通过分析紫外线色素水平随时间的变化得到他们的发现。故选B。
13.答案：D
解析：细节理解题。根据第四段“The researchers found that the changes in pigments differ between species, a result of the flowers structure.(研究人员发现，由于花的结构不同，不同物种的色素变化也不同)”可知，色素沉着的变化因花的结构而异，故选D。
14.答案：A
解析：推理判断题。根据最后一段“When the whole flowers get darker, insects might miss the flowers entirely. “This has a negative influence on plant reproduction,” Koski says.(当整个花朵变暗时，昆虫可能会完全错过花朵。“这对植物繁殖有负面影响，”科斯基说)”可知，当整朵花变暗时，昆虫可能会完全错过花朵，这对植物的繁衍有消极的影响，说明Koski对此现象是担忧的，故选A。
2.七选五
答案：ADGEB
解析：①根据前文“You probably are very much concerned about which direction you take in your career, but before working through the process of generating and refining specific career choices, helicopter up to 10,000 feet from where you can view your overall career map, answer the big questions and set your overall direction.(你可能非常关心自己在职业生涯中的方向，但在制定和完善具体的职业选择之前，扶摇直上一万英尺的高空，从高处查看自己总体的职业规划，回答一些重要问题，设定总体方向。)”和后文“What is your aim How long have you got (你的目标是什么？你还有多久？)”可知，空处应是对自己的职业规划提出的重要问题，与后文的问题并列，A项“你大致上要去哪里？”符合题意。故选A。
②根据后文“Write down examples of how you demonstrate key employability skills such as team work, leadership, and communication.(写下你如何展示关键就业能力的例子，如团队合作、领导力和沟通。)”可知，空处应是讲述要确定自己擅长的方面，D项“根据你的技能和经验，确定你擅长什么。”符合题意。故选D。
③根据后文“Go out and meet people, attend talks, go to relevant lectures, watch videos about industries and organizations, seek out websites that can give you objective and general career advice, for example, the open access Oxford university careers website.(出去与人见面，参加演讲，参加相关讲座，观看有关行业和组织的视频，寻找可以为你提供客观和一般职业建议的网站，例如开放访问的牛津大学职业网站。)”可知，后文讲述了可以为自己寻找职业建议的方法，由此可知，空处应是指出你需要一些关于职业的信息，G项“你的职业计划可能需要一些时间，因为现在你可能缺乏信息。”衔接下文。故选G。
④根据前文“Over time you can start to narrow down your choices and then choose one.(随着时间的推移，你可以开始缩小你的选择范围，然后选择一个。)”可知，前文讲述了你可以慢慢缩小选择范围直至做出选择，空处应评价这样做的作用，E项“这样，你会更加专注，从而更有可能实现你的目标。”符合题意，选项中的That way指代前文内容。故选E。
⑤根据前文“In 1804, Meriwether Lewis and William Clark set off with a compass and direction, and a general destination of mapping the new Louisiana territories in America. But they had no exact map.(1804年，梅里 瑟 刘易斯和威廉 克拉克带着指南针朝着确定的方向出发了，他们大体上的目标是绘制美国路易斯安那州新领土的地图。但他们没有准确的地图。)”和后文“Your career will be much longer but, like Lewis and Clark, it is about direction, not destination.(你的职业生涯会比这长的多，但是，就像刘易斯和克拉克一样，重要的是方向而不是目的地。)”可知，前文讲述了刘易斯和克拉克想要绘制美国路易斯安那州新领土的地图，但他们没有准确的地图，后文讲述了你的职业生涯会比这更长，由此可知，空处承上启下，应与刘易斯和克拉克花费的时间有关，B项“他们用了两年时间才成功完成考察。”符合题意。故选B。
