A．It takes less time to break down． B．It can be recycled at a low cost． C．It is produced without pollution． D．It has a wide range of applications． 解析：选A。细节理解题。根据第一段中“A lot of manufactured glass today made from sand and sodium．．．”可知，许多由沙子和碳酸钠制成的人造玻璃可以重复使用或熔化，再循环制成新物品，但它不会在环境中分解，将在垃圾填埋场中放置数千年。根据第二段中“That glass would have a smaller impact on the environment and can break down in a few weeks or in several months．”可知，新型玻璃的优点是它需要更少的时间来分解。故选A项。 2．Why did researchers implant glass beads inside mice? A．To assess whether the glass is biologically harmless． B．To investigate why amino acids are medically useful． C．To explore how long it takes for the glass to degrade． D．To observe if the glass can be melt down in mice's stomach． 解析：选A。细节理解题。根据第三段中“Throughout the experimental period, no mice exhibited any pain­related behavior．．．”可知，在整个实验期间，没有老鼠表现出可能由玻璃植入引起的任何与疼痛相关的行为，也没有老鼠出现明显的体重减轻。研究人员要在老鼠体内植入玻璃珠是为了评估玻璃在生物学上是否无害。故选A项。 3．What does the underlined word “hurdle” in Paragraph 4 refer to? A．The challenge of improving the heating­cooling procedure． B．Environmental problems caused by traditional glass． C．The difficulty of selecting materials for the glass． D．The instability of amino acids． 解析：选D。词义猜测题。根据第四段，尤其是该画线单词的前一句“Although amino acids do degrade over time in the environment, this biodegradable glass is not as durable as traditional glass, because amino acids can break down quickly in heat．”可知，这种氨基酸玻璃确实可以随着时间的推移而降解，但是它却不如传统的玻璃那样经久耐用，因为氨基酸在加热下会迅速分解。由此可推知，下文中的hurdle指的是氨基酸的不稳定性。故选D项。 4．Which of the following can be the best title for the text? A．Amino Acids Make Glass Tougher B．Amino Acids Cast New Light on Science C．Biodegradable Glass: Closer to Sustainability D．Biodegradable Glass: Ready to Hit the Market 解析：选C。主旨大意题。根据文章大意以及第二段中“In a study published recently in the journal Science Advances, a team at the Chinese Academy of Sciences' Institute of Process Engineering describe how they engineered biodegradable glass made from amino acids(氨基酸)．”可知，文章主要讲的是中国科学院的专家团队利用氨基酸研制出一种可降解的环保玻璃。故文章最好的标题是“可生物降解玻璃：更接近可持续性”。故选C项。 B All members of the Bishnoi community are India's original eco­warriors．They have been fighting to protect the environment for more than 500 years．The community believes in the sanctity (神圣) of all life, avoiding eating meat and cutting down living trees．Spread mostly in small villages across the state of Rajasthan, members draw inspiration from Amrita Devi, a Bishnoi woman killed in 1730 while trying to protect trees． The Bishnoi community was established in the 16th century by Guru Jambheshwar．Many of the Guru's 29 precepts—rules that govern the conduct of believers—are clear about the protection of nature．Devotees agree to “be merciful (仁慈的) to all living beings and love them” and “not to cut down green trees”． In 1730, 363 Bishnoi men, women, and children died for these beliefs．According to legend, a local king sent his men to get wood in order to build his palace．In an attempt to stop them, Amrita Devi rushed out of her home and wrapped herself around a tree．But the soldiers showed no mercy．Devi's last words were recorded as：“A person's head is cheaper than a fallen tree．” Other Bishnoi villagers—including Devi's three daughters—followed suit．In all, 363 Bishnois were killed．Their sacrifice (牺牲) is now honoured with a monument (纪念碑) in the village with each of their names on and topped with a figure of Amrita Devi． The event helped to inspire the modern­day Chipko movement, one of the strongest forest conservation movements in India．Many modern Bishnois are inspired by the devotion their ancestors showed． Advocate (拥护者) Rampal Bhawad co­founded the Bishnoi Tiger Force, an environmental campaign group．“We should live in harmony with nature and be kind towards all living beings, because in the future that is how the human race will move forward and develop，” he says． Nearby, 45­year­old Ghevar Ram has devoted his life to animals, running a rescue centre for injured creatures．“I treat animals like my own children．This is what we are taught from childhood，” he says． [语篇解读]本文是说明文。文章介绍了用生命保护绿树的生态战士——印度比什诺伊人。 5．What can we infer about the Bishnoi community according to the text? A．They are all vegetarians． B．They live together in a large village． C．They didn't form their beliefs until 1730． D．They didn't obey some of the Guru's 29 rules． 解析：选A。推理判断题。由第一段中的“The community believes．．．avoiding eating meat”可知，比什诺伊人从来不吃肉。由此可推知，他们都是素食主义者。 6．Why did Amrita Devi wrap herself around a tree? A．To keep herself awake． B．To hide from the soldiers． C．To set an example for the villagers． D．To prevent the tree from being cut down． 解析：选D。细节理解题。由第三段中的“In an attempt to．．．around a tree”可知，Amrita Devi把自己缠在树上是为了阻止国王派去的人砍伐树木。 7．What does the underlined part “followed suit” in Paragraph 4 mean? A．Cried out loudly． B．Passed out shortly． C．Did the same thing． D．Copied one's clothes． 解析：选C。词义猜测题。由本段内容可推知，很多村民效仿了Amrita Devi的做法，最后一起被杀害了，C项符合语境。 8．What is a suitable title for the text? A．Meet India's original eco­warriors B．Exploding numbers of Bishnoi members C．Growing environmental awareness of the Indians D．Reflect on the deep­seated beliefs of the Bishnoi people 解析：选A。主旨大意题。由全文内容可知，文章主要介绍了印度比什诺伊人绵延数百年对自然的恭敬和保护，A项概括了全文主旨。 Ⅱ．七选五(每题3分，共15分) Urban Wildlife Cities are diverse ecosystems．In addition to visitors from the wild, a large number of species share our urban areas．As our cities spread, we need to think about what it is like for other species to have human neighbors． Cities are built for humans．1( ) For example, most city parks are kept neat and tidy so that humans will find them beautiful．But when we cut grass or plant flowers, we destroy natural habitats． 2( ) When a bridge in Austin, Texas was repaired，engineers added small gaps running along the length of its bottom．This made a good home for bats, and soon the bridge was the home of thousands of bats．3( ) Now, they have come to value their winged (有翼的) neighbors．The bats are a tourist attraction, and they eat lots of bugs every night． There are also structures built with the aim of bringing wildlife into the city．The Olympic Forest Park is a good example．The park used native plants and created open, natural space for wildlife．The result is a zone in Beijing with over 160 species of birds．In many ways, the park is the opposite of a zoo．4( ) If we learn to share our space, we can become better neighbors to the wildlife around us．5( ) Our own future will be endangered too． A．They are built to protect birds． B．Our actions sometimes help other species． C．If we do not, more species will become extinct． D．They do not always provide suitable habitats for wildlife． E．Instead of being kept in cages, wildlife can move freely． F．At first, people were afraid of the bats and tried to get rid of them． G．They would sit on it and their droppings would fall into the water． [语篇解读]城市是多样化的生态系统，我们需要考虑其他物种与我们为邻的情况。如果我们学会分享我们的空间，我们就能成为周围野生生物更好的邻居。如果我们不这样做，我们自己的未来也将受到威胁。 1．解析：选D。根据空前一句及空后所举的例子，尤其是最后一句“但当我们割草或种花时，我们破坏了自然栖息地”可知，选项D符合语境。 2．解析：选B。根据空后所举的例子，尤其是“这为蝙蝠提供了一个很好的家园，很快这座桥就成了成千上万蝙蝠的家园”可知，选项B符合语境。 3．解析：选F。根据空后一句中的时间标志词Now可知，空处所填句子应与下文内容形成对比，故选F。 4．解析：选E。根据本段的内容尤其是空前的“The result is a zone in Beijing with over 160 species of birds．In many ways，the park is the opposite of a zoo”可知，空处内容应与空前一句为话题一致、内容上承接的关系，故选E。 5．解析：选C。空前一句表述人类与野生生物共享城市空间的好处，空后一句与空前一句形成对比，再结合空后一句中的too可知，选项C符合语境。 $$
