Question

    Every two years, the World Wildlife Fund(世界野生动物基金会) gives the Living Planet Report-a report on Earth’s health. The report for this year came out on Oct 30. It says that the number of animals like mammals (like elephants, lions and tigers), birds and fish falls by about 60 percent from 1970.

We are losing wildlife day by day. Humans should take this seriously, Vox Media said. It also plays an important part in our life. For example, a 2017-study said the number of flying insects(昆虫) fell by 75 percent in 30 years. Insects help plants have new seeds(种子). Without them, we will have a broken ecosystem. The report also shows that Earth has lost about half of its shallow water coral(浅水珊瑚) in the past 30 years. One-fifth of the Amazon rainforest disappeared in just 50 years.

This is mainly because of human activity. Climate(气候) change, losing living environment, environmental pollution and endless killing are some of the biggest reasons.

All over the world, people are cutting down forests, using too much water from rivers and putting waste into the sea. There is no human activity on only a quarter of the earth.

We need to find ways to meet the needs of our growing number of people, the WWF said. Different countries should work together to help the wildlife out of danger. Most importantly, humans cannot live by themselves in the world without other animals. To help the endangered wildlife is to help humans themselves.

【解析】

文章大意：文章主要讲的是世界野生动物基金会发布了《地球生命力报告2018》。该报告显示，自1970年以来，由于人类的破坏活动，鱼类、鸟类等动物数量已经下降了60%。

1.细节理解题。根据文章第一段中的“the World Wildlife Fund(世界野生动物基金会) gives the Living Planet Report-a report on Earth’s health”可知，世界野生动物基金会发布了关于地球健康的地球生命力报告，故选A。

2.词句推测题。根据文章第二段中的“a 2017-study said the number of flying insects(昆虫) fell by 75 percent in 30 years. Insects help plants have new seeds(种子). Without them, we will have a broken”“2017年的一项研究称，飞虫数量在30年内减少了75%。昆虫帮助植物有新的种子，没有它们，我们将会有一个破坏的”可推知飞虫帮助花授粉，是生态系统重要的一环，ecosystem是生态系统的意思，故选C。

3.细节理解题。根据文章第三段中的This is mainly because of…… some of the biggest reasons可知，这主要是因为人类的活动。气候变化、失去生存环境、环境污染和无休止的杀戮是失去野生动物的一些最大的原因，所以A项中的人们为了象牙杀戮大象是失去野生动物的原因；B项中工厂把污水倒进河里，是环境污染，也是失去野生动物的原因；C项中的学生们在植树节种树是保护环境，不是失去野生动物的原因，故选C。

4.细节理解题。根据文章第二段中的“We are losing wildlife day by day. Humans should take this seriously, Vox Media said. It also plays an important part in our life”可知，野生动物在生态系统中扮演着重要的角色，所以A说法是正确的，根据文章第四段中的“There is no human activity on only a quarter of the earth”可知，地球上只有四分之一的地方没有人类活动，所以B说法中的世界各地都有人类活动的说法是错误的；根据文章第二段中的“One-fifth of the Amazon rainforest disappeared in just 50 years”可知，亚马逊雨林五分之一在短短50年内消失了，所以C说法中的地球在50年内失去了大约一半的雨林的说法是错误的，故选A。

5.主旨大意题。通读全文以及最后一段中的“humans cannot live by themselves in the world without other animals. To help the endangered wildlife is to help humans themselves”可知，作者在文章里想让人们为一个更美好的世界而共同努力，故选B。
