1 . The world produces around 359 million tons of plastics each year. Plastics are certainly a big problem, but they don’t necessarily have to be. There are many ways we could set plastics on a different lifecycle. One that I have been working on is turning plastics into a hardy, reliable and sustainable building material.

Most people believe that plastics recycling is severely limited: only a few types can be recycled at all. This is unsurprising. The proportion(比例)of plastics that are recycled is minimal. But all polymers(聚合物)are, technologically, recyclable. Some of them can be used again and again to produce the same goods. Some can technically be reprocessed into new materials for different applications.

The problem is that recycling much of this plastic waste is currently unprofitable. But the amount of these materials all over the world is large and keeps on growing. What if this plastic waste could be used to produce something useful to the society? Many universities and business people are attempting to do this. Most solutions target mixed plastic waste and suggest applications different from the original ones. For example, several groups have developed building materials made of plastic waste. Plastics are strong, durable, waterproof, lightweight and recyclable—all key properties for construction materials. So what if all of this plastic waste could be turned into building materials for low-income populations? Existing initiatives are promising, but not yet reproducible on an industrial scale.

I study plastic waste with the aim of finding interesting ways to remove it from the environment. From agricultural waste to concrete waste, mixed with recycled plastics, there are many ways to obtain materials to produce bricks and other useful elements for buildings. So perhaps plastics are not necessarily the problem. They can be part of a pathway towards a more sustainable way of living.

1. What’s people’s common belief about plastic recycling?

A．Almost all plastic waste can be reused.	B．The methods are quite limited.

3 . Vanessa Burchill, a 12-year-old Dartmouth, N. S. girl, is growing and giving away hundreds of young milkweed so endangered monarch butterflies have somewhere safe to land. Her plan to save the monarch butterflies began about three years ago when her aunt showed her a chrysalis from her garden. She watched in wonder as a butterfly appeared and made its wings dry.

She’s now given out about 1,000 baby milkweed plants to people in Halifax through her Downtown Dartmouth Monarch Project. Her first group of milkweed this spring went in a matter of hours.

Monarch butterflies can’t survive without milkweed because ifs the only plant where they can lay their eggs. Burchill grows wetland milkweed. It is far less controllable than common milkweed, its cousin. Common milkweed is considered a harmful weed in U.S. It is often killed by people with chemicals.

This year, Burchill’s growing season began in February with seeds from the Mersey Tobeatic Research Institute. Anyone can message her on Facebook to pick up a pot of milkweed for free. Each pot has four small plants that people are encouraged to put in a sunny place in their gardens.

“When the monarchs finally appear from the chrysalis they need to be able to dry out their wings in the sun and when the plant doesn’t have full sun they can’t do that.” Burchill said.

Burchill has also started growing a butterfly garden in the park across the street from her house with the help of parents and neighbors. “We’re very proud of her and she’s quite focused,” said her dad, Nick Burchill. ‘‘Hopefully, it will create a nice pathway for monarchs.”

Burchill has only seen a handful of monarchs visit her yard and she’s still waiting to see a caterpillar on the milkweed. But she knows what she did is paying off when she sees the endangered butterflies visiting gardens she helps grow.

1. What encouraged Burchill to save the monarch butterflies?

A．Her monarch project.	B．Her aunt’s suggestion.
C．Her research on the butterflies.	D．Her experience in her aunt’s garden.

2. What can we learn from the second paragraph?

A．Selling milkweed becomes a profitable business.

B．Milkweed baby plants grow very quickly in spring.

C．The project is widely welcomed by the local people.

D．Monarch butterflies can’t survive without milkweed.

3. Why does Burchill plant wetland milkweed?

A．It provides the butterfly with enough water.	B．It is much safer than common milkweed.
C．It is encouraged by the U.S. government.	D．It grows everywhere in her hometown.

4. What is the attitude of Burchill’s father towards her action?

A．Supportive.

B．Uninterested.

C．Doubtful.

D．Worried.

The Dog Who Saved Our Family

We met Max at the pickup area of Alaska Airlines five years ago. He was a standard poodle(狮子狗)born on Valentine’s Day in 2017， and came to us in a small blue box. We had adopted him from an out-of-state raiser who posted the news on the social network. Our only request was that he have a calm behavior, able to bear the pushing and hugging of our eight-year-old daughter and six-year-old son.

We were a sweet little family:me,my husband, and our children, Sophie and Jake. But for years I’d felt as if we wouldn’t really be complete until we had a dog. Also, my husband worked in a business company and had to travel some 200 days a year for his job, and I knew I’d feel safer with a large animal sleeping by the door.

When we opened the box, the last piece of our puzzle fell into place. With his black hair and intelligent eyes,Max was beautiful. He was so small that he fit into the palm of my hand, his big paws lapping over the sides. He was also a little bit scared. As I pulled him close,I felt his heart pound and wondered if we’d done the right thing, taking him from his mother. But it was too late. Sophie and Jake were already fighting over who would hold him next and who should have the right to take a bath for him.

Over the following months, we spent endless hours watching Max play with his Kong toy or roll around the living room floor. Like most poodles, he was smart. He mastered house-training quickly and never chewed on our furniture or shoes. He considered himself one of us.

9 . Next time you’re having trouble solving a tricky puzzle, consider asking a nearby bumblebee.

A new study in the journal PLOS Biology finds that bumblebees can learn certain behaviors from each other, suggesting these social insects have a capacity for what we humans call “culture.”

In the past couple of decades, a growing body of evidence has shown that animals like chimps and birds show behaviors of learning. If what they learn lasts for a long time, it turns into a tradition. And culture is made up of multiple traditions. “Bumblebees, though, have some of the most complex behavioral abilities, nobody’s really thought to look at culture in such insects and generally assume they’re mostly driven by inborn factors instead,” says Alice Bridges, a behavioral ecologist at Anglia Ruskin University in England.

To prove them wrong, Bridges built a puzzle box, whose base held the reward: a drop of super sweet sugar water. The box was designed with a rotating (旋转) top that can be rotated by pushing either on a red tab clockwise or a blue tab anti-clockwise. Some bees were trained to push the red tab to get the sugar water while others pushed the blue one. Then, these tutor bees were placed inside different colonies (蜂群), along with the puzzle boxes.

The experiment ultimately played itself out. In colonies where the tutor bee had originally learned to push the red tab, the other bees in the colony usually pushed the red tab. In colonies where the tutor bee was trained to push the blue tab, their fellow bees also tended to do the same. In contrast, in the control groups without tutors, the bees sometimes learned how to open the boxes, but most of them would do it once or twice and then never again. “They perhaps hadn’t quite made the link between their behavior and the reward,” Bridges supposes.

“Many of us consider ourselves to be rather special…because we have culture, we can learn and we’re social,” Bridges says. “But now it turns out that even the bee also has culture, which is an uncomfortable truth: human culture, once thought unique, does not emerge ‘out of the blue’ but has obviously built on deep evolutionary foundations.

1. What is people’s common attitude to bumblebees having culture?

A．Positive.

B．Indifferent.

C．Interested.

D．Doubtful.

2. Why does Bridges place trained bees inside different colonies?

A．To test their learning capability in new settings.

B．To see if they will spread the secret of the boxes.

C．To evaluate their ruling power in various groups.

D．To observe if they will share their food with peers.

3. What does the last paragraph mainly talk about concerning the study?

A．Its appeal to the public.	B．Implications on cultural origins.
C．Its practical application.	D．Suggestions for future directions.

4. Which of the following can be the best title for the text?
