Plastic is piling up in ecosystems all over the world. Although its harmful impacts on both species and ecosystems have been documented, a few animals—like bowerbirds and hermit crabs—are doing what they can to recycle it. And according to a recent study, wild bees in Canada have joined the effort, which is a rare observation of behavioral flexibility in species especially insects, in increasingly plastic-rich environments.

The researchers found two species of leafcutter bees putting plastic into their nests. One of the bees they studied, the alfalfa leafcutter bee, normally bites off pieces of leaves and flowers while the second bee gathers sticky substances from trees. Leafcutter bees don't build big nests or store honey like honeybees, choosing instead small nests in underground holes, tree holes or cracks （裂缝）in buildings. But the researchers found that three of eight brood cells（育雏巢室）contained pieces of plastic bags, replacing 23 percent of the cut leaves in each cell on average.

While they don't make honey, alfalfa leafcutter bees still make money for the U. S. and Canadian farmers by pollinating（给......传授花粉）crops including alfalfa , carrots and melons. The European insects were introduced to North America in the 1930s for that purpose, and they've since become wild, joining the continent's many native species of leafcutter bees.

In a separate study conducted in Argentina between 2017 and 2018, researchers found a bee nest made entirely of plastic, which consisted of three separate cells. It's the first known example of such construction worldwide. Compared to the other nests the researchers examined, which were made of natural materials, this one had a pretty lower success rate of the bees' survival. One of the cells had a dead baby bee , another seemed to have housed an adult that had left the nest, and the third was unfinished.

1.What does the animals' use of plastic show according to the study?

A.How widely plastic is used.

B.How strange the behavior of wildlife is.

C.How some wildlife is adapting to plastic.

D.How plastic pollution has harmed them.

2.What do leaves mean to alfalfa leafcutter bees?

A.Food. B.Shelter.

C.A plastic substitute. D.Traditional nest materials.

3.Which is one characteristic of leafcutter bees?

A.They have great economic value.

B.They store honey like honeybees.

C.They prefer to live in tree holes.

D.They have evolved into a new species.

4.What was the nest made entirely of plastic like?

A.It might be warmer. B.It might be unhealthy.

C.It might be easy to finish. D.It might be recyclable.

If plastic had been invented when the Pilgrims (清教徒移民) sailed from Plymouth, England, to North America and the Mayflower had been stocked with bottled water and plastic-wrapped snacks, their plastic waste would likely still be around, four centuries later. If the Pilgrims had been like many people today and had simply thrown their empty bottles and wrappers over the side, Atlantic waves and sunlight would have worn all that plastic into tiny bits. And those bits might still be floating around the world’s oceans today, waiting to be eaten by unfortunate fish, and eventually perhaps by one of us.

Because plastic wasn’t invented until the late 19th century, and production really only took off around 1950, we have a mere 9.2 billion tons of the stuff to deal with. Of that, more than 6.9 billion tons have become waste. And of that waste, a shocking 6.3 billion tons never made it to recycling facilities.

No one knows how much unrecycled plastic waste ends up in the ocean, Earth’s last sink. In 2015, Jenna Jambeck, a university of Georgia engineering professor, caught everyone’s attention with a rough estimate: between 5.3 million and 14 million tons each year just from coastal regions. Most of it isn’t thrown off ships, she and her colleagues say, but is dumped carelessly on land or in rivers, mostly in Asia. It’s then blown or washed into the sea. It’s unclear how long it will take for that plastic to completely biodegrade (降解). Estimates range from 450 years to never.

Meanwhile, ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. Some are harmed visibly-strangled (勒死) by abandoned fishing nets. Many more are probably harmed invisibly. Marine species of all sizes, from fish to whale, now eat microplastics, the bits smaller than one-fifth of an inch across. On Hawaii’s Big Island, on a beach to which no paved road, I walked ankle-deep through mocroplastics. After that, I could understand why some people see ocean plastic as an approaching disaster, worth mentioning in the same breath as climate change.

And yet there’s a key difference: Ocean plastic is not as complicated as climate change. There are no mean waste deniers (否认者), at least so far. To do something about it, we have to remake our planet’s entire energy system.

“This isn’t a problem where we don’t know what the solution is,” says Jambeck. “We know how to pick up garbage. Anyone can do it. We know how to deal with it. We know how to recycle.” It’s a matter of building the necessary institutions and systems, she says--ideally before the ocean tums, for centuries to come, into a thin soup of plastic.

1.In the first paragraph the author emphasizes the fact that ______.

A.British people migrated to America four centuries ago

B.people have kept doing research in plastic for four centuries

C.there was no plastic pollution four centuries ago

D.plastic waste would remain in the ocean for four centuries

2.How are marine animals harmed invisibly by ocean plastic?

A.They eat microplastics.

B.They drown in microplastics.

C.They are coated with waste plastic bags.

D.They are struggling in abandoned plastic nets.

3.Which of the following statements is TRUE according to the passage?

A.People all agree reducing plastic production is the solution.

B.People tend to agree plastic waste has caused ocean plastic.

C.It has been scheduled to reverse the trend of climate change.

D.It has been scheduled to reverse the trend of ocean plastic.

People all over the world have some strange hobbies, and one of the most unusual in Britain is "trainspotting".　　 1..You'll see the grown.ups standing around a railway stations and other places where trains pass by, and you'll see them taking photos and exchanging notes with each other. So, what are they doing?

2. - the numbers on the front of the trains, or the make and model of the "locomotive (火车头)" -the part of the train which pulls all the other part. In the same way that some people collect toys or stamps, these men collect and exchange all kinds of details about trains and railways.

The idea goes back as far as 1942. That year, a young man named Ian Allan was working at Waterloo railway station in London.3., and quite a lot of the questions he received were very similar. He found himself getting a little annoyed at sending the sine replies to the same questions .so he had a word with him boss. He asked if he could write a brochure giving the answers to the most frequently asked questions. His boss said if he wanted to waste his time on such a project, that'OK.4..So he did. The brochure he wrote was the earliest version of the FAQs (常见问题) you see on websites nowadays.

The first 2,000 copies were all sold in days, and by the 1950s, a million copies of British Railways Locomotives were selling every year. Ian Allan went to become a successful publisher, and got an Order of the British Empire(OBE,大英帝国勋章) from the Queen in 1995.5..

A.But he should do it in his own time

B.The young man spent much time on it

C.They're looking for the trains they've taken

D.Well, they're collecting information about trains

E.It's usually men over the age of 40, but not always

F.He died in 2015, but his trainspotting hobby lives on

G.It was his job to answer letters from people about trains

Societies all over the world name places in similar ways. Quite often there is no official naming ceremony but places tend to be called names as points of reference by people. Then an organized body steps in and gives the place a name. Frequently it happens that a place has two names: One is named by the people and the other by the government. As in many areas, old habitsdied hard, and the place continues to be called by its unofficial name long after the meaning is lost.

Many roads and places in Singapore(新加坡) are named in order that the pioneers will be remembered by future generations. Thus we have names such as Stamford Road and Raffles Place. This is in keeping with traditions in many countries ---- in both the West and the East.

Another way of naming places is naming them after other places. Perhaps they were named to promote friendships between the two places or it could be that the people who used to live there were originally from the places that the roads were named after. The mystery is clearer when we see some of the roads named in former British bases. If you step into Selector Airbase you will see Piccadilly Circus ----obviously named by some homesick Royal Air Force personnel.

Sine places were named after the activities that used to go on at those places. Bras Basah Road is an interesting example, “Base Basah” means “wet rice” in Malay(马来语). Now why would anyone want to name a road “Wet Rice Road”? The reason is simple. During the pioneering days, wet rice was laid out to dry along this road.

A few roads in Singapore are named by their shapes. There is “Circular Road” for one. Other roads may have part of their names to describe their shapes, like “Paya Lebar Crescent”. This road is called a crescent(月牙) because it begins on the main road, makes a crescent and comes back to join the main road again.

1.We learn from Paragraph 1 that _____.

2.What does the underlined phrase “die hard” in Paragraph 1 probably mean?

3.Which of the following places is named after a person?

4. Bras Basah Road is named _______.

5.What can be inferred from the passage?
