Why did the orangutan（猩猩）cross the road? That’s not the start of a joke, but a question being asked by scientists studying these brilliant apes.

Brent Loken, who runs a group called Integrated Conservation, used camera traps to research into orangutans. That group protects ________ animals in Borneo, the largest island in Asia. Camera traps work by taking a quick photo, when something moves in front of them. In Borneo, scientists use the photos to ________ what the rare orangutans do when people aren’t ________?

Scientists have been studying orangutans in the rainforests for decades. And their data had suggested that the animals almost always traveled through the ________. They were ________ seen walking on the forest floor. Yet when Loken looked at the photos from his team’s camera traps, he got surprised that the apes were walking on the ground, ________ using logging roads（运材道路）and paths built by people.

Were these animals simply ________ to walk on the ground because logging had left too many ________? Or did they ________ down logging roads as convenient shortcut? “More ________ is needed,”

People are removing trees for logging, plantations and the building of the cities. The new findings suggest orangutans might be able to learn to ________ with some of these changes in their ________. It doesn’t mean the animals can survive ________ forests. But it does suggest there might be ways to log forests in a way that won’t greatly ________ these apes.

Stephanie Spehar, primatologist at the University of Wisconsin, Oshkosh, agrees. “The new study doesn’t mean they’re fine in areas with no trees,” she says. “Orangutans clearly need the forest to ________.

Milo is a rescue dog adopted by 20-year-old Makayla Swift. One morning in November 2021, Swift opened her front door in Silver Spring, Maryland, and Milo _________ running.

Milo ran to the house across the street. He seemed unsatisfied with this house, so he ran to the one next door, Swift on his _________. Milo started scratching on the front door.

Swift was _________, because not everyone wants a strange dog on their property. But as she tried to _________ Milo away, she could hear a sound coming through an open upstairs window.

It was a voice yelling “Help!”

Hours earlier, around 4 a.m., Sherry Starr, 85, had risen from her bed. All of a sudden, standing there between the toilet and the tub, she slipped and fell heavily on the floor. She was _________ between the toilet and the tub and could not move at all. Starr was _________ and thought she was just going to die there.

For the next few hours, Starr practiced yelling: “Help! Help! Hellllp!”

Her voice was very _________ that no one could hear. Luckily, Milo _________ heard Starr the moment Swift opened her own front door.

Swift called the emergency number 911. When the ambulance workers arrived, they thought they’d have to remove the toilet to _________ Starr, but instead, they gave one last pull and out she popped. Though she was black and blue all over, Starr __________ a trip to the hospital.

Swift has known her own share of distress. Two years ago, her mother died. She says that Milo has helped her with her grief. “That dog is a blessing,” she says.
