A

Every day as the sun rises, Ma Hongyi, a 66­year­old farmer, can be seen patrolling (巡逻) Yuncheng Salt Lake with his dog in Yuncheng City, North China's Shanxi Province.

Ma still remembers the day when he first saw two big pink birds wandering through the water. “I had never seen such pretty birds. They were even taller than me, with long wings，” Ma recalls. He was later told that the birds were flamingos, a rare sight in China, which were listed on the International Union for Protection of Nature's Red List of endangered species in 2013. From that day on, Ma started his second career as a volunteer to prevent human beings from interfering__with the wildlife. “The birds are attracted by the good environment，” Ma says. “I will do my best to protect the lake so that birds can come here every year.”

Yuncheng Salt Lake covers an area of 132 square kilometers and used to serve as a salt production base. As the country began attaching greater importance to environmental protection, an ecological (生态的) protection and development center was set up in 2012 to carry out regular ecological protection and restoration (修复) of the lake. “The greatest value of the Salt Lake lies in its ecology, which should be properly restored and protected，” says Chu Xianghao, mayor of the city. The lake area hosts 292 types of wild animals, along with 782 plant varieties, some of which are newly recorded species in the country.

After patrolling the lake as a volunteer for over four years, Ma was employed by the local government to help with wildlife protection in 2019. “The lake's ecology is getting better，” Ma says, adding that he looks forward to the arrival of the flamingos every year. “Some of them are my old friends，” he says.

1．What does the underlined phrase “interfering with” in Paragraph 2 probably mean?

A．Bringing benefits to. B．Losing control of.

C．Sharing space with. D．Causing problems to.

答案：D

解析：词义猜测题。根据画线短语后文“The birds are attracted ... here every year.”可知，马红义为了保护这个湖，让鸟儿每年都能来这里而开始巡逻盐湖，他的目的是阻止人类活动对野生动物造成不良影响。因此，interfering with意为“干扰”，和D项意思相近。故选D。

2．Why does Ma patrol Yuncheng Salt Lake every day?

A．To serve as a keeper of the lake.

B．To observe the rare flamingos closely.

C．To admire the scenery around the lake.

3．What can be inferred about Yuncheng Salt Lake from Paragraph 3?

A．It is still used as a salt production base.

B．The restoration of it will be carried out soon.

C．The protection of its ecology is of great importance.

D．It's home to 292 types of endangered wildlife.

答案：C

B

Nearly 6，000 years ago, ancient people climbed the dry, rocky hills in what is now the Nigerian Sahara and carved large images of giraffes into the sandstone. The quite detailed Dabous giraffe rock art is one of many ancient carvings of giraffes found in Africa. We are still attracted to giraffes today, but many of these animals are at risk, largely due to habitat loss and illegal hunting.

Giraffes make their homes in many different environments with varied levels of human influence. Each area has unique environmental conditions and protection measures. There is no one­size­fits­all approach to protecting giraffe habitats and promoting harmonious living between giraffes and humans.

To understand how giraffes are traveling across Africa, conservation ecologists (保护生态学家) like me are studying how they interact with their habitats across large geographic regions, using space­age technology and advanced statistical (统计学的) approaches that ancient people could have hardly imagined.

We have carried out a large giraffe­tracking study to better understand giraffes' movements. Each tracking operation contributes to local studies by telling us something interesting about giraffe behavior. The study is also important for guiding local management of giraffes. We share giraffe location data (数据) in real time with officials in protected areas to guide day­to­day conservation actions.

Overall, we've found that on average, each animal has a home range of about 140 square miles and travels about 8.5 miles every day. One of the biggest movers in our study, a female northern giraffe in Niger that traveled among communities raising farm animals in the dry Sahel, covered a home range of nearly 1，500 square miles—larger than the land area of Rhode Island.

Giraffes' movements changed significantly based on the supply of food sources and the level of human presence. They tended to move less in places with rich resources or significant human development. They traveled faster and covered larger areas when they were moving between resource­rich areas and more heavily developed areas.
