Ken Scott kicked of the covers and leapt out of bed at his home in the Rocky Mountain town of Mullan,Idaho.It was 6 a.m.on January 7, 2020, and he was on a mission: He’d just heard on the radio that the nearby Silver Mountain Resort had been blessed with nearly a foot and a half of new snow. As a ski addict who’d worked in the industry for the past 30 years as a ski patroller (滑雪巡逻员)and equipment salesperson, he didn’t want to miss this perfect skiing chance. These conditions are what skiers live for-even experienced and skilled as Scott, who, at 55, still skied 100 days a year.

When Scott reached Silver Mountain’s locker room, he ran into his friend Warren, 58, a former ski instructor who had also been a regular on these slopes for more than two decades.

“Can you believe it?” he said as they changed into their boots. “Sixteen inches! Are you ready?”

For the next hour, the pair skied on various runs under a lightly gloomy sky, making fresh tracks. They were both in a playful mood. Finally, they reached 16-to-1, an expert-level trail, which was now open. It had been closed all season over concerns that skiers might cause an avalanche (雪崩). But that morning, patrollers had cleared loose snow on the peak, reducing the chance of a snowslide.

“What do you think?” asked Warren.

“Let’s go for it!” Scott replied.

When they reached the top of 16-to-1, Warren excitedly looked back at Scott. The huge, toothy grin on his bearded face was what he needed. He pointed his skis downhill and took off. So thrilled were they that they isolated everything around them. Flying on the trail, despite the biting wind, their hearts burnt with passion for this great skiing. Whoomph! A sudden roar from behind nearly deafened them.

4 . The herd of 14 wild Asian elephants wandering around in southwestern China's Yunnan province successfully went through the last natural barrier on its way home and returned to its traditional habitat in Pu' er city on Friday.

At 1 am, the elephants, which had left their habitat in Xishuangbanna National Nature Reserve, crossed the Babian River and entered Ning'er county in Pu' er city, one of the three major habitats of Asian elephants in Yunnan. The northbound trip, lasting about 18 months, finally ended without any harm to either the elephants or local residents. The herd departed from its traditional habitat in Xishuangbanna Dai autonomous district last year and started traveling north in April. It passed through eight counties in the province during the journey. In June, it eventually reached the suburbs of Kunming, the provincial capital.

The herd started its journey with 16 members, but three of them dropped out, while two calves were born on the journey. In June, a bull elephant broke away from the group and wandered off on his own. In July, the bull elephant was lifted into a cage on the back of a truck and returned to Xishuangbanna.

The Asian elephant is listed as an endangered species by the International Union for Conservation of Nature. The animal, which can be found in the areas of Yunnan bordering Myanmar and Laos, is also under first-class State protection in China. Shen Qingzhong, a senior engineer from the Xishuangbanna National Nature Reserve, said it's inevitable（难免的）that the elephants will make another journey in the future as migration is a normal activity for elephants. “Historically, Asian elephants used to live in many parts of the country. Migration is in their nature. It helps the species expand its territory and have more chances to improve its gene pool by mating with different groups,” he said.

The forestry department and the provincial government plan to develop a national park, which aims to provide habitat protection for the elephants and a balanced relationship with residents.

1. Which of the following is True?

A．The elephants finally settled in the downtown of Kunming.

B．The journey took the elephants over two years.

C．The elephants' habitat is far away from Kunming.

D．The elephants moved towards the south of Yunnan.

2. In June, how many elephants continued their journey together?

A．13.	B．14.
C．15.	D．16.

3. What can we infer from the engineer's words?

A．Elephants can benefit from migration.

B．Migration is an abnormal activity for elephants.

C．Elephants have less chances to improve their gene.

D．Elephants used to live in its territory.

4. What does the article mainly talk about?

A．Elephants in Yunnan.	B．How to protect the elephants.
C．The activities of the elephants.	D．Elephants return from the journey.
