4 . An Inuit-developed app, named SIKU after the Inuktitut for “sea ice”, allows local communities from Alaska to Greenland to connect traditional knowledge with scientific data to track changes in the environment, and make decisions about how to manage wildlife.

A group of Inuit elders and hunters from Sanikiluaq, Nunavut, thought up the idea for SIKU more than ten years ago to document and understand the changing sea ice they were seeing in southeastern Hudson Bay. The group turned to the local non-profit Arctic Eider Society (AES) to develop a web-based platform (平台).

Over the years, SIKU has developed, and recently, the elders saw that the platform could help address a familiar challenge: sharing knowledge with younger people who often have their noses in their phones. In 2019, SIKU was reintroduced as a full-fledged (全面发展的) social network — a platform where members can post photos and notes about wildlife sightings, hunts, sea ice conditions and more. The posts tell stories of hunting and traveling; the impacts of climate change and industrial activity; and the traditions, diets and illnesses of local animals.

Inuit communities are already using the app to inform important decisions. In 2021, for example, elders in Sanikiluaq were worried that the local reindeer (驯鹿) population had reduced, so the Hunters and Trappers Association used SIKU to survey hunters and look at recent reported harvest rates. The information led the association to close the hunt for a short time to reduce pressure on the population and to reintroduce hunting slowly when the number of reindeer increased.

Traditionally, Inuit communities shared this information orally (口头上地). “We have lived in the environment for centuries and know about the wildlife. Now armed with SIKU, information is documented in a way that other people will understand. The advantage of SIKU is that it’s part science and part Inuit knowledge and it supports community-driven research,” says Lucassie Arragutainaq, a co-founder of AES.

1. What was the purpose of developing SIKU in the beginning?

A．To raise money for AES.	B．To pass on Inuit tradition.
C．To attract more visitors to Inuit communities.	D．To record and learn about the changing sea ice.

2. Why is reindeer mentioned in paragraph 4?

B．To advise people to pay more attention to SIKU.

D．To tell the benefits of the Hunters and Trappers Association.

3. What is the attitude of Lucassie Arragutainaq toward SIKU?

D．Supportive.

4. What can be a suitable title for the text?

9 . With a brain the size of a pinhead, insects perform fantastic navigational (导航的) abilities. They avoid obstacles and move through small openings. How do they do this, with their limited brain power? Understanding the inner workings of an insect’s brain can help us in our search towards energy-efficient computing, physicist Elisabetta Chicca of the University of Groningen demonstrates with her most recent result: A robot that acts like an insect.

In search of the neural (神经的) mechanism that drives insect behaviour, PhD student Thorben Schoepe developed a model of its neuronal activity and a small robot that uses this model to navigate. Schoepe’s model is based on one main principle: always steer towards the area with the least apparent motion.

He had his robot drive through a long “corridor”— consisting of two walls with a random print on it—and the robot centred in the middle of the corridor, as insects tend to do. In other virtual environments, such as a space with obstacles or small openings, Schoepe’s model also showed similar behaviour to insects.

“The model is so good,” Chicca concludes, “that once you set it up, it will perform in all kinds of environments. That’s the beauty of this result.”

The fact that a robot can navigate in a realistic environment is not new. Rather, the model gives insight into how insects do the job, and how they manage to do things so efficiently.

Chicca explains, “Much of robotics is not concerned with efficiency. We humans tend to learn new tasks as we grow up and within robotics. This is reflected in the current trend of machine learning. But insects are able to fly immediately from birth. An efficient way of doing that is hardwired in their brains. In a similar way, you could make computers more efficient.”

1. Why does Chicca want to study how the insect brain works?

A．To make computers more efficient.	B．To make use of insects’ brain power.
C．To understand the habit of insects.	D．To reveal the inner part of insects’ brain.

2. What does the underlined word “steer” in paragraph 2 mean?

A．Stretch.

B．Stare.

C．Drive.

D．Work.

3. How did Chicca feel at the performance of her robot?

A．Regretful.

B．Shocked.

C．Confused.

D．Satisfied.

4. What are the last two paragraphs mainly about?

A．How to make a robot that acts like an insect.

B．Why insects navigate more efficiently than robots.

C．Why a robot can navigate in a realistic environment.

D．How humans tend to learn new tasks as they grow up.
