Tibetan antelopes live on the plains of Tibet, Xinjiang, and Qinghai. During the 1980s and 1990s, the population of Tibetan antelopes 1 (reduce) by more than half due to human hunting. 2 (save) this species from extinction, the Chinese government placed it under national protection. The establishment of the Changtang National Nature Reserve 3 (effective) increased the antelope population. While Tibetan antelopes were removed 4 the endangered species list in 2015, the government would continue the protection programmes. After all, there still exist the 5 (threat) to the Tibetan antelope.
I went to the Changtang National Nature Reserve to observe Tibetan antelopes along with my guide, Zhaxi, 6 works at the Changtang National Nature Reserve. Watching the graceful animals move slowly across the grass, I was struck by their beauty. Reminded of 7 danger they are in, I realised that much should be done to protect them. As Zhaxi said, not only are we trying to save the animals, but also we’re trying to save 8 (we).
In the evening we went back to camp, where I 9 (reflect) on what I saw and what Zhaxi told me. Only if we change our way of life can we really save the planet. I believe we are no longer a threat to wildlife and to the planet by 10 (live) in harmony with nature.

答案：
刷课文改编填空
1. were/was reduced reduce在此处是谓语动词，与主语是被动关系，且主语是 the population，故填were/was reduced。
2. To save save在此处应用动词不定式形式作目的状语。故填To save。
3. effectively此处修饰动词，应用副词。故填 effectively。
4. from remove…from…为固定搭配，意为“去掉/去除/拿走……”。故填from。
5. threats threat前的谓语 exist使用的是复数形式，所以此处是指多种威胁。故填 threats。
6. who此处 ________ works at the Changtang National Nature Reserve是非限制性定语从句，修饰 my guide，关系词在定语从句中作主语，所以应用关系代词。故填who。
7. the danger此处是特指它们身处的危险，所以应用定冠词修饰。故填the。
8. ourselves当宾语与主语指同一对象时，宾语应用反身代词。故填 ourselves。

[课标全国I 2019]阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。
The polar bear is found in the Arctic Circle and some big land masses as far south asNewfoundland. While they are rare north of 88°, there is evidence 1 they range all the way across the Arctic, and as far south as James Bay in Canada. It is difficult to figure out a global population of polar bears as much of the range has been 2 (poor) studied; however, biologists calculate that there are about 20, 000 —25, 000 polar bears worldwide.
Modern methods 3 tracking polar bear populations have been employed only since the mid-1980s, and are expensive 4 (perform) consistently over a large area. In recent years some Inuit people in Nunavut 5 (report) increases in bear sightings around human settlements, leading to a 6 (believe) that populations are increasing. Scientists have responded by 7 (note) that hungry bears may be congregating（聚焦）around human settlements, leading to the illusion（错觉）that populations are 8 (high) than they actually are. Of 9 nineteen recognized polar bear subpopulations, three are declining, six 10 (be) stable, one is increasing, and nine lack enough data.

答案：
刷语法填空
【语篇导读】北极熊生活在北极圈和一些广阔的陆地上，南至纽芬兰。由于对北极熊活动范围的研究甚少，很难计算出全球北极熊的数量；然而，生物学家计算出全世界大约有2万到2.5万头北极熊。
1. that句意为：虽然它们很少出现在北纬88度（的地区），但有证据表明，它们的活动范围遍及北极地区，甚至南至加拿大的詹姆斯湾。根据句意及设空前的 evidence可知，此处应填的是同位语从句的引导词。再分析设空后的句子成分可知，从句不缺成分，且句意完整，因此应用that引导该同位语从句。故填that。
2. poorly句意为：由于对北极熊活动范围的研究甚少，很难计算出全球北极熊的数量……设空处修饰动词 studied，应用副词。故填 poorly。
【知识拓展】形容词和副词的基本用法
（1）形容词可作定语、表语和补语：常位于名词前，作定语，修饰名词；位于系动词之后，作表语；位于宾语之后，作补语。（2）副词在句中常作状语，用于修饰动词、形容词、副词或句子。
3. of/for句意为：追踪北极熊数量的现代方法从20世纪80年代中期才被运用，而且在大面积范围内持续进行的成本很高。method of/for（doing）….为固定搭配，意为“（做）……的方法”。故填of/for。
4. to perform句意见上一题解析。根据“主语+be+adj.+to do”结构可知，此处应用动词不定式，其中动词不定式用主动形式表被动意义。故填 to perform。
5. have reported句意为：近年来，努纳武特的一些因纽特人报告说，在人类居住地附近看到熊的次数有所增加，这让人们以为熊的数量正在增加。根据时间状语 In recent years可知，本句应用现在完成时。故填 have reported。
6. belief句意见上一题解析。设空处作介词to的宾语，且其前有不定冠词a限定，其后有同位语从句修饰，应用名词形式。故填belief，意为“观点；信念”。
【方法总结】
冠词后，修饰或限定成分（of./定语从句/名词性从句等）前应用名词。
7. noting句意为：科学家们已作出回应，称饥饿的熊可能聚集在人类居住地附近，导致了熊的数量比实际数量要多的错觉。设空处作介词by的宾语，应用动名词形式。故填 noting。
【易错警示】
（1）note如果是名词，意为“笔记；便签；字条；音符；注解；钞票”，设空后的从句不好解释。（2）by作为介词，表示“通过”时后常加动词的-ing形式（除非是固定短语，如 by hand，by means of）。
（3）本题解题（在不确定note的意思，或者混淆了和 notice意思的前提下也几乎不会影响考生做题）的思路和重点应该关注前面的介词by，by+ doing是本题的考点，意为“通过做”，如by working hard（= through hard work）
8. higher句意见上一题解析。根据句意及设空后的比较级的提示词than可知，设空处应填形容词的比较级，故填 higher。
【方法总结】
设空后有比较级的提示词than，故填 higher。
9. the句意为：在已知的19个北极熊亚种群中，有3个正在减少，6个保持稳定，1个正在增加，还有9个缺乏足够的数据。根据句意及设空处后的 nineteen recognized polar bear subpopulations可知，此处特指“已知的19个北极熊亚种群”，应用定冠词限定，故填the。
10. are句意见上一题解析。分析句子结构可知，本句由多个分句并列组成。其中设空处所在分句的主语为six，为复数概念，谓语应用复数，且下文中的lack也是提示；本句叙述一般事实，应用一般现在时。故填are。
