3 . David and Alicia Tschirhart adored their Yellow Lab, Marley, but they never knew just how much, until that day back in 2014 when they were hiking with him in hills near their San Diego home.

“Alicia went off the path to grab a walking stick to help through the path,” David recalled. “And Marley all of a sudden darted (猛冲) from me and he started clawing the ground where Alicia was reaching for a walking stick. And I didn’t know what was happening. Alicia kind of fell back. When I looked more closely, I saw that it was a rattlesnake,” he told journalist Tracy Smith.

Rattlesnakes are common on these trails, which are very steep and miles from any hospital. And the Tschirharts didn’t have cellphones with them. For Alicia, who was four months pregnant, a snake bite could have been a disaster. Thankfully, 12-year-old Marley scared the snake away, and a few months later, the Tschirharts’ first daughter Maddie was born.

But by then, Marley had been diagnosed with cancer, and by Thanksgiving weekend 2014, it was clear the end was near. And their love for Marley was so strong that they couldn’t really let it go. So, the Tschirharts turned to ViaGen Pets, of Austin, Texas, a company that has cloned hundreds of pets for a multitude of grateful owners.

For as much as $50,000, the company will culture the cells, create embryos, implant them in a surrogate (代孕母亲), and deliver a clone of your loved one.

Marley’s clone, Ziggy, an energetic yellow ball. But to David and Alicia, he’s nothing less than Marley reborn. “He is exactly the twin of Marley,” said David. “So, he’s in, I guess, the same environment. So really, he’s become the same dog.”

And while pet cloning is still debatable, it can mean, for some at least, that with the right amount of love, science and money, you never really need to say goodbye.

6 . David lost his beloved dog Baya before Christmas two years ago. Baya was active and cute. David’s family spent many days _________ for their furry (毛茸茸的) family member. The kids said they wouldn’t want any _________ from Santa Claus. They just wanted to get their dog back. All attempts to find her turned out to be _________. Baya was nowhere to be found. It seemed that the family wouldn’t have any more _________.

Two years later, a homeless dog _________ alone on a busy road. Someone _________ it to the Animal Protection Association (协会).

According to a new study, the leading cause of death of birds near power lines is not electrocution (触电), but unlawful shooting. “We need to know how birds are dying so that we can come up     1     some ways to reduce their deaths,” said Thomason, leader of the research team. Between 2019 and 2022, they     2     (find) 410 dead birds and 66% were killed by guns. “It is really difficult     3     (know) what’s going on. Sometimes people shoot birds for fun. Sometimes they do this just to protect their animals on the farm. Anyway, unlawful shooting should be prevented,” said Thomason.
