Saihanba is one of China’s largest forests. It lies in the north of Hebei Province. Saihanba means “beautiful
and high mountains”．
Around the 10th century, the rulers of the Liao Dynasty made it a royal (皇家的) hunting place because it was
home to beautiful forests, green grasslands, clear lakes and different kinds of wild animals. Emperor Kangxi of the
Qing Dynasty liked Saihanba so much that he made hunting there a royal festival. The royal festival finally stopped
in the 19th century for lack of money and the place had to be open to the public. After that, the cutting down of
trees and wildfires changed green Saihanba into grey deserts. By the 1950s, the beauty of Saihanba had completely
disappeared (消失) with only one tree left. The tree is now famous as the “Tree of Honour”．
On seeing the tree, Chinese scientists made up their minds and dreamed of restoring Saihanba. In February
1962, the plans were made and more than 120 foresters joined 242 local people in Saihanba to begin rebuilding it.
Over the next 55 years, those first treeplanters fought against many difficulties to plant trees. After they died, their
children and relatives followed them and went on with their hard work of planting trees.
Today, the scientists’ dream has come true and there is beautiful grassland and flowers again around the “Tree
of Honour”. Chinese people successfully changed Saihanba in the past halfcentury.
1．What’s the right order of the events in Paragraph 2?
①Saihanba became a royal hunting place.
②Saihanba was a desert and its beauty disappeared.
③Saihanba wasn’t closed to the public any more.
④Saihanba turned into the place for royal hunting festivals.
A．①③②④ B．①③④②
C．①④③② D．①④②③
2．What does the underlined word “restoring” in Paragraph 3 probably mean?
A．Looking around. B．Bringing back.
C．Arriving at. D．Travelling to.
3．According to Paragraph 4, how does the writer feel about Chinese people?
A．Proud. B．Worried. C．Surprised. D．Nervous.
4．What is the best title of this passage?
A．Saihanba: Past and PresentB．The Largest Forest in China
C．The Disappearing Saihanba
D．The “Tree of Honour” in Saihanba
【答案】1．C 2．B 3．A 4．A
【解析】

林、成功恢复美丽森林的变迁历程，展现了中国人重建生态的决心与成就。
1．细节理解题。根据“Around the 10th century, the rulers of the Liao Dynasty made it a royal hunting
place”“Emperor Kangxi…made hunting there a royal festival”“The royal festival finally stopped…the place had to
be open to the public”“By the 1950s, the beauty of Saihanba had completely disappeared”可知，事件顺序为①成
为皇家猎场→④成为皇家狩猎节举办地→③对公众开放→②变成荒漠、美景消失，故选C。
2．词句猜测题。根据前文“the beauty of Saihanba had completely disappeared”和后文“begin rebuilding it”可
知，科学家看到仅剩的树后，决心重建塞罕坝，让它恢复原貌，“restoring”意为“恢复”，与“Bringing
back”同义，故选B.。
3．观点态度题。根据“Today, the scientists’ dream has come true”“Chinese people successfully changed
Saihanba in the past halfcentury”中的“successfully”可知，作者对中国人改造塞罕坝的成就持自豪的态度，
故选A。
4．最佳标题题。全文以时间为线，依次介绍了塞罕坝过去的皇家猎场风貌、沦为荒漠的过程，以及如今
恢复秀美风光的现状，核心围绕塞罕坝的过去和现在展开，故选A。
九、任务型阅读。
根据短文内容在文章后表格中的空白处填入一个最恰当的词，每空一词。
In recent years, China has tried its best to protect the environment and achieved great results. These
achievements include many areas. Let’s take a closer look at some of these successes.
Leading in Renewable Energy
China is now the world’s largest producer of solar and wind energy. By building huge solar farms and wind
turbines (涡轮机), the country offers clean power to millions of homes. For example, in 2022, China’s solar power
production reached over 390 million kilowatts (千瓦), becoming the top in the world. This helps cut coal use and
air pollution.
Greener Lands and Forests
China has planted billions of trees to keep soil in place and fight against desertification (沙漠化). The Great
Green Wall project, set up in 1978, has built forests covering over 46 million hectares—an area larger than
Germany! The government has also returned over 28 million hectares of farmland to forests or grasslands since
1999, which is good for biodiversity (生物多样性) protection.
Clearer Skies in Cities
Air pollution used to be a serious problem in cities like Beijing. However, some laws have made air quality
better. Beijing’s average PM2.5 level dropped by about 63% between 2013 and 2021. Many cities now have more
blue sky days than before.Promoting Green Transport
In 2023, over 60% of the world’s electric vehicles (EVs) (电动汽车) were made in China. China leads the
world in EV production and sales. Cities like Shenzhen have already used electric buses and taxis completely
instead of oil ones, lowering carbon emissions (排放) and noise pollution.
China’s environmental achievements show that progress is possible when people and government work
together. As students, we can also make a difference by saving energy, recycling, and reusing. After all, protecting
the Earth is everyone’s duty!

Kids Who Care: Saving Nature One Step at a Time
Part 1: Read and Explore
When we think of explorers, we often imagine adults climbing mountains or diving deep into the ocean. But
today, many young people are also exploring nature—and protecting it.
Meet Leo, a 13-year-old boy from Brazil. He lives near the Amazon Rainforest. Last year, he noticed that
more and more trees were disappearing. He felt sad and worried. He decided to act. With the help of his teacher,
Leo started a small group called "Amazon Kids." Every Saturday, Leo and his friends go to the forest to pick up
rubbish and plant new trees. They also make posters to teach people in their town why the rainforest is important.
In just one year, their group has planted over 500 trees. They have also cleaned up three kilometers of
riverbanks. Leo says, "The Amazon is called 'the lungs of the earth.' If we lose it, we lose our future. We are young,
but we can still make a difference."
Far away in Australia, 14-year-old Mia is doing her part too. She loves the Great Barrier Reef. When she
learned that coral bleaching was killing the reef, she wanted to help. Mia started an online campaign called "Reef
Heroes." She shares photos and videos of the reef on social media. She also teaches people how to use reef-safe
sunscreen and why it matters.
Mia's campaign has reached over 10,000 people. Some of her followers have started their own beach cleanup
groups. "You don't need to be a scientist to protect nature," Mia says. "You just need to care."
Both Leo and Mia believe that small actions can lead to big changes. They prove that age is not a barrier—
anyone can be an explorer and a protector of our planet.

Task 3: Connection to Life
Near my school, there is a small river. It used to be clean, but now there is plastic rubbish along the banks. Fish and
birds are losing their home. My classmates and I could start a "Clean-Up Saturday" once a month. We could also
put up signs to tell people not to throw rubbish into the river. Small actions can bring the river back to life.
（我们学校附近有一条小河。它曾经很清澈，但现在岸边有塑料垃圾。鱼和鸟儿正在失去家园。我和同学
们可以每个月组织一次"周六清洁日"。我们还可以立起告示牌，告诉人们不要往河里扔垃圾。小小的行动
能让河流重获生机。）
