6 . In the late 1970s, archaeologists (考古学家) uncovered the remains of a woman and a young dog, her hand resting on the puppy’s chest in a 12,000-year-old village.

The find is some of the earliest evidence of the bond between humans and dogs. But even after years of study researchers are divided on how this bond began. Did it arise over thousands of years, as early dogs became tamer (驯服的) and more accustomed to human behaviors? Or was this fire already burning in the ancestors of dogs: the gray wolf?

Christina Hansen Wheat, a behavioral ecologist at Stockholm University, and workmates hand-raised 10 gray wolves from the time they were 10 days old. When the animals were 23 weeks old, a caregiver led them one at a time into a mostly empty room. Over the course of several minutes, the caregiver exited and entered the room, sometimes leaving the wolf alone, sometimes leaving it with a complete stranger. The team repeated the experiment with 12 23-week-old Alaskan huskies (哈士奇), which they’d raised similarly since puppyhood.

For the most part, the scientists saw few differences between the wolves and the dogs. When their caregiver entered the room, both species scored 4.6 on a five-point scale of “greeting behavior”—a desire to be around the human. When the stranger entered, dog greeting behavior dropped to 4.2 and wolf to 3.5, on average, suggesting both animals made a distinction between the person they knew and the one they didn’t. It’s this distinction that the team counts as a sign of attachment.

In addition, dogs barely paced—a sign of stress—during the test, while wolves paced at least part of the time. However, the wolves stopped pacing almost entirely when a stranger left the room and their caretaker returned. Hansen Wheat says that’s never been seen before in wolves. It could be a sign, she says, that the animals view the humans who raised them as a “social buffer”.

For her, that’s the most interesting part of the study. “If this is true, this sort of attachment is not what separates dogs from wolves,” she says. In other words, it didn’t have to be bred into them by humans, but could have been the seed we selected for, and then strengthened over thousands of years.

9 . In the deepest dive in a manned submersible(潜水器), US explorer Victor Vescovo spotted and video-recorded a plastic bag and a pile of candy wrappers on the seabed.

His _________ of plastic waste 11.2 kilometers below sea level in the Challenger Deep in the Pacific Ocean, the deepest known point in the Earth’s oceans, means there is _________ on this planet plastic waste cannot reach, _________ it has been found on Mount Qomolangma and in both Arctic and Antarctic waters.

Since the patent(专利) for plastics was _________ in 1907, 8.3 billion tons of plastic products have already been produced, of which 6.3 billion have been poured into oceans _________ processing.

Most of the discarded(丢弃) plastic products _________ in the ocean. In the Pacific Ocean, plastic garbage and other waste have already formed a(n) _________ that’s 1.6 million square kilometers in size. That is the size of Mongolia.

Every year, about 8 million tons of plastic waste flow into the ocean. It is _________ that the total weight of plastic waste will reach 12 _________ tons by 2050, more than the total weight of oceanic fish.

This plastic waste __________ life in the oceans and on the land alike by filling in their stomachs so they cannot eat, or __________ around their bodies so they cannot breathe. It pollutes the __________ and prevents plants’ roots from digging deep into the ground. Plastic micro-particles(微粒) also join the water __________ and enter the bodies of animals, including humans. As humans are at the top of the food __________ , plastic micro-particles accumulate inside our bodies.

We must do something to __________ the situation. Don’t get plastic bags at the supermarket and take your own reusable one __________ . Give up fast delivery lunches and instead cook or go to the restaurant. Get into the __________ of sorting your garbage.

But that’s so much __________ said than done. Environmentalists have been __________ behavioral changes for at least three decades, yet we __________ to use a growing amount of plastic products.
