On August 5 just after 7:30 pm, Mike Estepa suffered a massive heart attack. The crazy cyclist was 40 kilometres into his Sunday ride when he stopped by the side of the road to text his family saying he’d be home in about 30 minutes. Moments later, he was lying in the ditch, unconscious.
Larissa Arthur was driving back to Calgary from a hike in Field, BC with a friend. It was a warm and sunny day, and the two were chatting when a flush of yellow caught Arthur’s eye. She immediately pulled off the road.
As Arthur approached the figure, she feared the worst: Estepa was covered with ants and exhibited no signs of life. “There was no pulse and he wasn’t breathing,” says Arthur. A bystander called 911 and Arthur, a registered nurse, started chest compression. She and two other drivers took turns carrying out

CPR for the next 15 minutes before medical teams arrived and whisked Estepa away.
Two days later, when Estepa woke up in the hospital, he was shocked to learn he had gone into cardiac arrest (心脏停搏). How did this happen, and,why was he lucky enough to have survived? He was full of gratitude and needed to speak with the woman who had saved him, whom he named his “angel”.
“It was emotional,” says Arthur of her meeting with Estepa a few weeks later. Saving his life had extra importance for her: the hike she was returning from that day was one of 100 hikes she’s planned to honour her father, who died in 2017 after he fell during a hike that Arthur was meant to be on. “I couldn’t save my father’s life,” Arthur says, “but this was a chance for me to save someone.”

主题 大象无长牙
词数 345
While elephants born without tusks(长牙) are not unheard-of, they normally are made up of just 2 to 6 per cent of the population. However, that is not the case at Mozambique’s Gorongosa National Park, where 33 per cent of female elephants born after the country’s civil war ended in 1992 are tuskless.
This is not the first time researchers have observed a serious change in the population of elephants that have suffered severe poaching(偷猎) losses. At the Ruaha National Park in Tanzania, 35% of elephants 25 years or older and 13% of those younger than 25 are now without tusks. A 2008 study published in the African Journal of Ecology found that the number of tuskless females at
体裁 说明文
Zambia’s South Luangwa National Park went from 10.5 per cent in 1969 to almost 40 per cent in 1989, largely due to illegal hunting for ivory.
Thus far, the result of poaching has largely affected female elephants. Poole explains, “Because males require tusks for fighting, tusklessness has been selected against in males, and very few males are tuskless. For African elephants, tuskless males have a much harder time breeding and do not pass on their genes(基因) as often as tusked males.”
However, if the killing of males with the most impressive tusks continues at this pace, it could result in a generation of elephants with much smaller tusks. Poole says, “If poachers select according to the size of tusks, they will tend to kill older males with very large tusks, therefore taking out of the population of breeding-aged males who also happen to have very big tusks. Those males then no longer pass on their genes for large tusks. In this manner, heavy poaching will select out genes for large tusks.”
The recent ban on ivory in both the US and China should help eliminate, or at least reduce, elephant poaching. However, scientists are not sure how long it will take for the elephants with a higher rate of tuskless females to reverse the trend.
( )5.What is the function of the first paragraph? A.To make comparisons. B.To introduce the topic. C.To appeal to attention.
D.To give readers a surprise.
( )6.What may cause tuskless females to increase in Zambia? A.War’s effect. B.Imperfect management. C.Illegal hunting.
D.The decrease of population.
( )7.What can we learn from what Poole says? A.Tuskless elephants are being neglected.
B.Heavy poaching for large tusks will be forbidden.
C.Tusklessness influences the heredity(遗传) of male elephants. D.Older males with very large tusks are soon dying out.
( )8.What does the underlined word “eliminate” in Paragraph 5 mean? A.Remove. B.Decline. C.Compete. D.Unite. Ⅱ.完形填空
