Cleaners help to keep cities clean. This month a park in France welcomed six very special cleaners. They are
crows(乌鸦)!
Workers at the park teach the crows to pick up small pieces of trash (垃圾). And they also teach the crows to
move the trash into a small box. After helping clean the park they get bird food for their hard work, the BBC reported.
This shows that “nature(自然) itself can teach us to take care of the environment (环境),” Nicolas de Villiers,
head of the park, told AFP.
The park chose crows because they are smarter than other birds. Earlier this year, scientists made a special

【解析】
1. dressed.考查固定搭配。get dressed为固定搭配意为“穿好衣服”，所以此处填dressed。故答案为dressed.
2. for.考查固定搭配。根据句意可知，此处填介词for，leave for为固定搭配，意为“动身前往”。故答案为for。
3. best.考查副词最高级。根据“so we go to see them frst”可知，妈妈最喜欢熊猫like为动词，用副词修饰，所以用well
的最高级形式best。故答案为best。
4. eating.考查动词。根据“Look!”可知，有些熊猫正在树下吃东西，空格前有are，所以填现在分词eating。故答
案为eating。
5. really.考查副词。happy为形容词，用副词修饰real的副词为really，衣蛾“真正地”。故答案为really。
6. can’t.考查情态动词。根据妈妈的提醒“Don’t do that!”可知，在动物园里喂动物是不允许的，结合give可知，此
处填can’t，意为“不能”。故答案为can’t。
7. rules .考查名词。根据前面"one of"可知，rule用复数形式rules。故答案为rules。
8. friendly. 考察形容词。根据“Animals are our good friends”可知，我们应该对动物友好，所以用形容词friendly，
意为“友好的”。故答案为friendly。
9. in.考查介词。根据下一句“We can do somethingto save them.”可知，很多动物现在处境很危险，结合danger可知，
填in，in danger意为“在危险中”。故答案为in。
10. to save.考查不定式。根据前面父母对孩子的教导可知，他们呼吁一家人做些什么“来拯救”动物，所以空格处
用to save表示目的。故答案为to save。

动词不定式。故答案为：to save。
3. usually.考查副词。根据句意，雪豹通常来自蒙古中国和印度等国家，这里用副词usually作时间状语。故答案为：
usually。
4. them.考查代词。根据句意，人们很难看到它们，所以很难知道它们在世界上还剩下多少，结合句子结构，空处为
宾语成分，所以应填入提示代词的宾格形式them。故答案为：them。
5. living.考查非谓语动词。根据句意，据说野生雪豹不到6000只，提示词live与主语snowleopards为逻辑上的主动
关系，所以用非谓语形式living。故答案为：living。
6. are.考查be动词。根据句意，成年雪豹体重在60到120磅之间，结合本句主语Adult snow leopards为复数形式，
所以be动词用复数are。故答案为：are。
7. From.考查介词。根据句意，从头到尾巴，它们有六到七英尺半长，空后有介词 t0，结合语境，可理解为
from...to...从.…...到.....的固定搭配。故答案为：From。
8. a.考查冠词。根据句意，雪豹有一条长长的尾巴，空后的tail尾巴为单数名词，故空处缺少冠词a。故答案为：a。9. usefu1.考查形容词。根据句意，它(雪豹)的尾巴很有用，be动词后用形容词usefu，有用的，来修饰。故答案为：
useful。
10. and.考查连词。根据句意，它(雪豹的尾巴)可以帮助雪豹保持平衡和保暖，空前的keep balance及空后的keep warm
