二、综合填空
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。
When nature meets man-made roads, it's seldom a good thing. A large number of animals get killed by cars every week. So engineers try to build green bridges. These bridges help keep animals and people 1 (safe).
The idea of green bridges isn't really new. The first one was built in France in the 1950s. As well as 2 (German), which has added more than 800 green bridges since 1950, Canada and the United States are also trying to protect local wildlife 3 building animal bridges over the years.
4 there are different kinds of green bridges, their designs are similar. First, they are usually quite wide, giving animals plenty of room to move. Second, they 5 (cover) with soil and plants to look like the forest or land on both sides of the roads. Lastly, they are 6 (wide) at the ends, spreading out where they meet the land. This helps collect animals to the bridge and guide them out when they leave.
Since 1996, there have been 11 kinds of big animals in Canada's Banff National Park. These animals include bears, elk and cougars. They 7 (walk) across green bridges more than 200,000 times. What's more, in some places where these green bridges were built, 8 number of accidents between animals and cars has gone down by 90%.
These crossings are clearly a step in the right direction 9 (offer) safety to wildlife. And with these bridges, both animal and human 10 (dead) on roads will continue to go down.

【文章大意】本文是一篇说明文。文章主要介绍了绿色桥梁(动物通道)的作用、设计特点及其对保护野生动物和减少交通事故的积极影响。

5. are covered 6. wider 7. have walked 8. the
9. to offer 10. deaths

【分析】
首先，我们需要先通读全文，了解文章是关于绿色动物桥的说明，明确文章主旨后，再逐个分析每个空的语境和语法要求：
1. 第1空，根据“keep”的用法“keep sb./sth. + adj.”，要填形容词来表示让动物和人保持安全的状态；
2. 第2空，前文提到法国，这里对应的是国家，要把表示“德国人”的German转换为国家名词；
3. 第3空，这里是说保护野生动物的方式，通过建造桥梁，需要用表方式的介词；
4. 第4空，前后句是让步关系，“有不同种类的桥，但设计相似”，所以要填让步连词；
5. 第5空，主语“they”指代桥梁，和“cover”是被动关系，桥被土壤和植物覆盖，要用被动语态；
6. 第6空，根据语境，桥的末端和其他部分对比更宽，要用形容词比较级；
7. 第7空，看到时间状语“Since 1996”，要想到现在完成时的用法；
8. 第8空，这里指事故的数量下降，要区分“the number of”和“a number of”的用法；
9. 第9空，这里是表目的，“朝着正确方向前进是为了给野生动物提供安全”，要用不定式作目的状语；
10. 第10空，这里需要名词作主语，要把形容词dead转换为名词，且结合语境用复数形式。
【解析】
1. 考查形容词作宾语补足语。“keep animals and people + adj.”表示“使动物和人类保持某种状态”，safe是形容词，意为“安全的”，符合语境，故填safe。
2. 考查名词转换。前文提到法国（France），此处应对应国家，German表示“德国人；德语”，其对应的国家名词是Germany，故填Germany。
3. 考查介词用法。“by doing sth.”是固定结构，意为“通过做某事”，此处表示通过建造动物桥来保护野生动物，故填by。
4. 考查让步连词。根据句意“虽然有不同种类的绿色桥梁，但它们的设计相似”，前后句是让步关系，Although/Though意为“虽然；尽管”，符合逻辑，故填Although/Though。
5. 考查一般现在时的被动语态。主语they指代green bridges，和动词cover是被动关系，即“桥梁被土壤和植物覆盖”，一般现在时被动语态结构为“am/is/are + 过去分词”，主语是复数，故填are covered。
6. 考查形容词比较级。根据语境“桥的末端更宽”，是和桥的其他部分作对比，wide的比较级是wider，故填wider。
7. 考查现在完成时。时间状语“Since 1996”是现在完成时的标志，现在完成时结构为“have/has + 过去分词”，主语They是复数，walk的过去分词是walked，故填have walked。
8. 考查固定搭配。“the number of”表示“……的数量”，后接可数名词复数，作主语时谓语动词用单数，此处指动物和汽车事故的数量下降，故填the。
9. 考查不定式作目的状语。此处表示“这些通道显然是为给野生动物提供安全而迈出的正确一步”，不定式to offer作目的状语，故填to offer。
10. 考查名词转换。此处需要名词作主语，dead是形容词，其名词形式是death，结合语境指动物和人类的死亡事件，要用复数形式deaths，故填deaths。
【答案】
1. safe
2. Germany
3. by
4. Although/Though
5. are covered
6. wider
7. have walked
8. the
9. to offer
10. deaths
【知识点】
形容词作宾补、被动语态、固定搭配
【点评】
本题是语法综合填空题，考查了多种语法知识点和固定搭配，需要学生在理解文章主旨的基础上，结合语境和语法规则进行填空，对学生的语法综合运用能力和语境理解能力有较高要求，同时也渗透了动物保护的环保理念。

三、任务型阅读
阅读下面短文，并根据所读内容在文章后的表格里填入最恰当的单词，每个空格只填一个单词。
Poop(粪便) Made Useful
Animal waste is becoming a treasure! Scientists have found a special way to use animal poop. They call their project "Poo Zoo". This project helps protect wild animals.
Animal poop has living cells (细胞). These cells have DNA，which gives us important information for breeding(繁育) programmes and animal protection. This is very important as some wild animals are getting endangered.
Usually，getting a piece of wild animal skin for research is hard. People have to catch the animals and make them sleep. This not only takes a lot of time but can also do harm to the animals.
To help endangered animals，Professor Suzannah Williams from University of Oxford in the UK created the "Poo Zoo" project. The idea is to collect living cells from animal poop and grow the cells in labs(实验室).
At first，the team tried many ways to collect the cells from the mouse poop while keeping them fresh. After they tried to improve their skills，scientists turned to the elephant poop. They cleaned the poop carefully and took out the living cells.
Professor Williams told CNN that the team had successfully collected live elephant cells many times. She hopes people use this method in the wild by looking for animal footprints and fur to find poop.
However，it's not easy to make life from these living cells now. Poop has a lot of bacteria(细菌)，so scientists need better ways to grow healthy cells. They also need to learn more about animal reproduction(繁殖) to turn these cells into babies，said Vice magazine.
