5 . Directions: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.

Imagine you are out fishing on the high seas - the wind and water are clean and comfortable and you begin bringing up your first catch of the day. That's when everything goes wrong. Your fishing nets are tangled up (缠成一团) in older, abandoned fishing tool, and you're unable to untangle them. Your equipment    1    (ruin), and all of the fish you have worked so hard to catch are trapped. They will die    2    you are unable to draw or free them. Ghost fishing has claimed yet another victim.

Ghost fishing is what abandoned fishing tool does. It still catches fish, but no one benefits. Trapped fish die and attract scavengers (清道夫)    3     also get caught, creating a vicious cycle. In fact, lost fishing tool, or "ghost tool," is among    4    (great) killers in the oceans. This tool further reduces the already declining number of fish.

Environmental agencies estimate that 10 percent of all seawater litter is lost or deserted fishing tool    5    (equal) 640,000 tons every year. Fortunately, these agencies are asking why this is happening and what    6     be done to stop it.

It's not the intention of the majority of fishermen to lose their tool. In most circumstances bad weather is to blame. But in other cases fishermen throw their tool in the ocean on purpose, risking expensive fines. But to them, it's worth the risk    7    (free) up space onboard, cut fuel costs or avoid paying handling fees.    8     equipment loss is accidental or not, a strategy involving tool identification seems to be a practical solution.

By marking tool with electronic tags and utilizing GPS technology, owners are more likely to recover lost tool and less likely to abandon it. Currently, ownership regulations are reportedly very weak. Leading the effort for tagging fishing tool and creating accountability is the GGTI (Global Ghost Tool Initiative).    9     (launch) in 2015, the GGTI is the first organization of its kind. It's brought together an organization of governments, fishing-industry executives, seafood companies and non-profits. Their efforts to get back and recycle the tool    10    (improve) marine environment, protecting fish and fishermen's way of life.

Ghost fishing poses a serious threat to the fishing industry worldwide, and a global effort is needed to solve it.

6 . Directions: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.

In 1831, a 22-year-old English biologist called Charles Darwin boarded the HMS Beagle in Plymouth and set off on an incredible voyage. His aim was to observe the natural world in places     1     had not been studied in much detail. Almost 200 years later, another mission, the Darwin 200, has invited a team of conservationists to retrace back the Beagle’s journey.

HMS Beagle’s mission was to map the harbours of South America. Darwin was invited along     2     (survey) the natural world. His observations on the Galapagos Islands, around 560 miles off the coast of Ecuador, changed the way Darwin saw nature,     3     (lead) to Darwin’s most famous work: his theory of evolution (进化论). This explained     4     species change over time to adapt to their environments, a process called natural selection. It has been described as “    5     (big) single idea in the history of human thought”.

What is Darwin 200’s mission? The Darwin200 ship     6     (sail) more than 40,000 miles and stop at 32 ports in four continents. Specially     7     (choose) conservationists will join at different stages for a week each to carry out wildlife studies.    8     the journey, the ship’s crew will make films that explain Charles Darwin’s discoveries.

The Darwin 200 team will travel in a 50-metre-long Dutch sailing ship called Oosterschelde, which     9     (build) in 1918 and has been restored fully for this voyage. The ship’s captain said, “She has sailed the distance from here to the Moon and back twice!    10     I may handle the most difficult situations, I trust her to bring me back home safely.”

The ship is due to reach the Galapagos Islands in April 2025

7 . Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible. 

Microplastics: Out of Sight, Out of Mind?

People joke that someone suffering from paranoia (妄想症) sees danger everywhere, thinking someone is out to get him. In the case of microplastics, you don’t need to have paranoia to be worried about them being everywhere, because they basically are!

What exactly are microplastics? They are particles (颗粒) of any type of plastic that are less than 5 millimeters in diameter (直径). They have resulted from the plastic pollution widespread in the world today.

When plastic is exposed to environmental forces, it breaks down into these tiny particles, which, in turn, do not disappear but continue to exist for hundreds or even thousands of years. Every piece of plastic that has ever been made is still on Earth today, except for what has been burned. Often mistaken for food, plastics and microplastics in oceans and on beaches are often consumed by marine animals, which is harmful. Research has linked microplastics to cancer and other problems in animals.

Whatever you think about these particles, taking them in is easier than you think. When you heat food in a plastic dish in the microwave, microplastics get into your food. The water from a plastic water bottle contains the particles as well. After taking surveys of microplastics in air, water and seafood, scientists estimate that people may easily be eating 5 grams of plastic a week. Researchers don’t know yet if or how this will affect humans. Microplastics have been found in human tissue samples, and no one yet knows how long they stay in the human body or what problems may arise.

Not until the amount of plastic waste in the world is reduced will microplastics decrease. So, while the evidence is still missing of the effect microplastics have on people’s health, reusing and recycling plastic is a no-brainer.

8 . Antarctic Tourism: Should We Just Say No?

More people are visiting Antarctic, the frozen continent than ever before.     1     This has brought a new urgency to the question of how much, if any, tourism should be allowed on the icy continent.

The distance most visitors travel to reach Antarctica makes carbon emissions a serious problem.     2     One study calculated that each tourist between 2016 and 2020 was effectively melting around 83 tonnes of snow, due largely to emissions from vacation ships.

    3     The Antarctic Treaty, established in 1961 to provide governance for the continent, operates on a consultative basis, which means all 56 parties have to agree before a change can be put into action. The last major decision on tourism was a measure passed in 2009 that prohibits vacation ships carrying more than 500 passengers from making landings. That regulation has still not officially been carried out as not every signatory country has accepted it domestically.

There is clear agreement that something needs to change, but no agreement on what those changes should be.     4    

A．The number of visitors hit 100,000 for the first time this tourist season, a 40% jump over the previous record.

B．The Antarctic is at risk not just because of the breakability of its environment, but due to the lack of a single governing body.

C．Should landings be made at a larger number of sites for instance, or should we aim to keep the human footprint as small as possible?

D．If what you really want is to connect with snow and ice and you’re in the northern half, can you catch a train to the nearest snow region instead?

E．The average per-person carbon emissions for an Antarctic tourist are 3.76 tonnes – about the total sum that an individual typically generates in an entire year.

F．There is so little regulation now that almost anything that will protect the areas by an official legal source rather than self-regulated would be really positive.

9 . The Fight against Fast Furniture

Fast furniture is a term that refers to furniture that is produced cheaply and quickly. These items are often bad for the environment because they are made from materials that break easily and need to be replaced often.     1    

To help protect the environment, a movement to move away from fast furniture has begun. Many companies are joining the fight by finding cleaner ways to manufacture furniture. For example, IKEA has agreed to switch to using renewable or recycled materials for their furniture by the year 2030.     2    

There is also a push to encourage shoppers to buy more used furniture for their homes. Small businesses that help transform old chairs and sofas into completely new products have even popped up recently. At the end of the day, consumers will play the most important role in the fight to end fast furniture. Shoppers should try to think more about the long term when preparing to purchase new furniture. They should stay away from furniture that is made from cheap materials like fiberboard or plastic because they will often fall apart after a few years.     3    

A much better alternative is furniture made from real wood because it won’t break as easily. If wood furniture is damaged, it can often be repaired to last longer. High-quality metals are another good material, as they are durable. If the furniture is no longer fit for use, these metals can still be recycled and used to make new products.

    4     So, the next time you buy furniture, think about whether it’s something that will last a long time or it’s just fast furniture that will break soon and go into the trash.

A．It has also designed a special program that lets people return used furniture pieces to its stores so they can be fixed and used again by consumers.

B．This would help to reduce overall waste, as it would extend the life cycle of old furniture items.

C．Although these items may cost less initially, they are more expensive because they will need to be replaced sooner than traditional pieces of furniture.

D．This creates a lot of pollution, as the furniture ends up buried in landfills where it can harm the soil.

E．Homeowners are looking for furniture that is kinder to the environment.

F．By choosing furniture that’s made to last, we can help reduce waste and protect the environment.

10 . THE GLOBAL WASTE TRADE IS ESSENTIALLY BROKEN

Cut into hillside in northern Malaysia stands a large, open-air warehouse. This is a recycling factory, which opened last November. On a very hot afternoon in January, Shahid Ali was working his very first week on the job. He stood knee-deep in soggy, white bits of plastic. Around him, more bits floated of the conveyor belt and fell to the ground like snowflakes.

Hour after hour, Ali sorts through the plastic jumble moving down the belt, picking out pieces that look off-color or soiled-rejects (废品) in the recycling process. Though it looks like backbreaking work, Ali says it is a great improvement over his previous job, folding bed-sheets in a nearby textile factory, for much lower pay. Now, if he eats simply, he can save money from his wages of just over $l an hour and send $250 a month to his parents and six brothers and sisters in Peshawar, Pakistan, 2,700 miles away, “As soon as I heard about this work, I asked for a job,” says Ali, 24, a bearded man with glasses and an easy smile. Still, he’s working 12 hours a day, seven days a week. “If I take a day off, I lose a day’s wages,” he says.

In the warehouse, hundreds of bags are stacked more than 60 feet high-each stuffed with plastic wrappers and bags thrown away weeks earlier by their original users in California. The fact that the waste has traveled to this distant corner of the planet in the first place shows how badly the global recycling economy has failed to keep pace with humanity’s plastics addiction. This is an ecosystem that is deeply dysfunctional, if not on the point of collapse: About 90% of the millions of tons of plastic the world produces every year will eventually end up not recycled, but burned, buried, or dumped.

Plastic recycling enjoys ever-wider support among consumers: Putting yogurt containers and juice bottles in a blue bin is an eco-friendly act of faith in millions of households. But faith goes only so far. The tidal wave of plastic items that enters the recycling stream each year is increasingly likely to fall right back out again, casualties of a broken market. Many products that consumers believe (and industries claim) are “recyclable" are in reality not, because of hard economics. With oil and gas prices near 20-year lows, so-called virgin plastic, a product of petroleum feed-stocks, is now far cheaper and easier to obtain than recycled material. That unforeseen shift has yanked the financial rug out from under what was until recently a practical recycling industry. “The global waste trade is essentially broken,” says the head of the global plastics campaign at Greenpeace. “We are sitting on vast amounts of plastic with nowhere to send it and nothing to do with it.”

1. What is the author’s attitude towards Shahid Ali?

A．Critical.

B．Merciless.

C．Indifferent.

D．Sympathetic.

2. What most probably causes the problem of global waste recycling?

A．The prices of oil and gas have been increasing.

B．Tons of wastes travel so far before being recycled.

C．Recyclable products are not really recycled.

D．Governments don’t support the recycling industry.

3. What does the italicized word “dysfunctional” mean in the passage?

A．Out of stock.

B．Far from pleased.

C．Full of energy.

D．Out of order.

4. What is the author’s purpose of writing this article?

A．To illustrate how plastic waste has been recycled in the world.

B．To warn people that the global waste trade is essentially broken.

C．To analyze the relationship between consumers and factories.

D．To solve the conflict between the recycling industry and governments.
