参考答案
一、完形填空答案解析
C。句意：BBC的纪录片《地球脉动》带我们踏上了一段从雨林到海洋的奇妙旅程。根据“from the rainforest to the sea”可知，这是一段旅程（journey）。
A。句意：它展示了我们星球的美丽。根据上文提到的“Planet Earth”和“rainforest”、“sea”等，可知此处指我们的星球（planet）。
C。句意：令人惊讶的是，一个叫《我们的星球》的节目做得甚至更多。根据“even”和“than”可知，此处为比较级，表示做得更多（more）。
D。句意：我们真的对地球上生命的多样性感到惊讶。be surprised at 为固定搭配，意为“对……感到惊讶”。
C。句意：它呼吁我们在为时已晚之前拯救地球。call on sb. to do sth. 意为“呼吁/号召某人做某事”，符合语境。
A。句意：我们在未来20年所做的事情将决定地球上所有生命的未来。根据句意，现在的行为会影响未来，因此是决定（decide）未来。
B。句意：《我们的星球》于2019年4月5日播出。come out 意为“（书、电影、节目等）出版，发行，播出”，符合语境。
B。句意：超过600人花了四年多时间工作于这个节目。spend time doing sth. 是固定搭配，根据语境，是花了四年时间制作（working on）这个节目。

B。句意：它也表明，在科学家的帮助下，许多濒危动物的数量正在增长。根据常识和语境，需要科学家帮助来增加数量的应该是濒危（endangered）动物。
二、阅读理解答案解析
A。推理判断题。文章第一段以两个问题“Do you love nature?”和“When it comes to the Himalayas, what do you have in your mind?”开头，引出话题。因此，作者是通过提问来开始这篇文章的。
D。细节理解题。根据第二段中的“There are flowers everywhere”和第三段中的“There are also a lot of wild plants, such as trees and grass... some endangered animals live in the valley, like snow leopards”可知，在山谷里可以看到花、草、树和雪豹。
D。词义猜测题。划线词“them”所在的句子是“Some of them are hard to find anywhere else in the world!”，其前一句是“There are also a lot of wild plants, such as trees and grass, in the Valley of Flowers.”。根据上下文逻辑，“them”指代的是前一句提到的“wild plants”。
B。文章结构题。第一段引出“花之谷”这个话题；第二、三段详细介绍了“花之谷”里的动植物；第四段介绍了它作为国家公园的现状和规定。因此，文章结构为“总-分-总”或“引出话题-具体介绍-现状说明”，即①/②③/④。
A。主旨大意题。文章主要介绍了印度“花之谷”的地理位置、独特的动植物以及作为国家公园的保护情况，旨在陈述关于“花之谷”的事实。
三、短文填空答案解析
is。考查动词时态。句子主语是“It”，指代前文的“The sanfu period”，且句子描述的是一个客观事实，故用一般现在时，be动词用“is”。
an。考查冠词。“excellent”是以元音音素开头的单词，其前的不定冠词应用“an”。
from。考查固定搭配。suffer from 是固定搭配，意为“遭受，患……病”。
painful。考查词性转换。此处需要一个形容词作表语，来描述“That”（指代流鼻涕这件事）的性质，pain的形容词形式是“painful”，意为“痛苦的”。
first。考查序数词。for the first time 是固定搭配，意为“第一次”。
completely。考查词性转换。此处需要一个副词来修饰动词“changed”，complete的副词形式是“completely”，意为“完全地”。
my。考查代词。此处需要一个形容词性物主代词来修饰名词“health”，I的形容词性物主代词是“my”。
unhealthy。考查词性转换。根据“staying up late”可知，这是一种不健康的习惯，故用healthy的反义词“unhealthy”。
illnesses。考查名词复数。此处泛指治疗各种疾病，ill是可数名词，应用其复数形式“illnesses”。
but。考查连词。前半句“Technology is changing fast”和后半句“the traditional medicine is still important”之间存在转折关系，故用连词“but”。
