Is Banning Single-use Plastic the Right Option?
The harmful effects of using plastic are becoming increasingly apparent. Plastic does not decompose, but breaks down into smaller and smaller particles. It threatens our nature as well as our health. One popular solution to the problem is to prohibit single-use plastics. In the UK, supermarkets are being encouraged to set up plastic-free aisles, in which the food is displayed loose, and shoppers are encouraged to make more environmentally-friendly choices in packing and transporting their food.
Such plans are well-intentioned, but it may not be beneficial to eliminate(清除) the use of single-use plastic altogether. One of the fields where single-use plastic has a vital role is the food industry. When food or fresh goods are packed in plastic, they are protected and preserved, helping them remain fresher and keeping them from spoiling. Single-use plastic is also crucial in the medical industry. This is not just because of its low cost. It helps to prevent the spread of infection and that is the biggest benefit of the material in the medical field.
Replacing plastic with other materials is neither simple nor straightforward, mainly due to the challenge of finding an alternative that combines all the most desirable plastic properties. For example, glass products are a potential alternative, but cleaning them would be extremely expensive while increasing the risk to health. Another issue is that alternative materials to plastic are often more environmentally harmful than plastic. Take paper bags, for example. Research by the Northern Ireland Assembly shows four times more energy is required to manufacture a paper bag than a plastic bag. If people respond by simply using other materials, a ban on single-use plastic can end up making the problem worse.
Clearly there is a need to reduce plastic waste and its impact on the environment. However, simply banning their single use may not be the best option.

Cities in the Sea
They may be small, but they build big things! Coral polyps (珊瑚虫), which live in the warm, shallow parts of the Earth’s oceans, are probably the biggest builders on the planet. Coral polyps turn calcium from seawater into a hard material called limestone. Slowly, they build up a hard skeleton (骨架) around their bodies. When polyps die, their skeletons remain. Young polyps attach themselves to the old skeletons and make new skeletons. Over time, weird and wonderful shapes are slowly built up into amazing coral reefs (珊瑚礁).
Scientists sometimes think of coral reefs as underwater cities. A quarter of all known marine species live in reef habitats―there are nearly a thousand coral species. Reefs are also home to millions of sea creatures, like fish, crabs, turtles, and sharks.
Humans don’t live in coral reef cities, but we benefit from them. Reefs create jobs for people in the fishing industry and other related businesses. Coral reefs are also popular for divers一many countries benefit from the tourists that they attract. Lastly, chemicals from reef creatures help scientists create new medicines, which help doctors treat different illnesses.
Coral reefs are very important, yet we don’t take good care of them. Environmental problems have already killed about twenty percent of the world’s reefs. About half of the remaining reefs are dying, and experts believe all of Earth’s coral reefs will be in danger by 2050.
Why are the reefs in such trouble? For one thing, people catch too many reef fish and often damage the reefs—divers sometimes break off pieces of coral.
Polluted water also causes problems because reef-destroying algae grows in dirty water. Even air pollution hurts coral reefs. Global warming causes warmer ocean water, which can cause polyps to lose helpful algae. Without that algae, coral turns white. This is called "bleaching”，and if it continues, the coral dies.

4 . 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.
There are many reasons why some cats are bad-tempered; their temperament can be influenced by their upbringing or they are simply born that way. However, even the sweetest, most affectionate cats can suddenly become bad-tempered and behave out of character. According to veterinarian Dr Katrina Warren, the problem can generally be solved, but you’ll need to look for underlying issues.
Changes in a cat’s behaviour can often be explained by a health problem. Pain can cause cats to behave very differently, and it’s easy to mistake a problem as behavioural, when in fact it is medical. Should you observe a significant change in your cat’s behaviour, then a visit to the vet is the best place to start? Watch out for changes in eating, drinking or litter-box habits. Also hiding and avoiding being touched. Be sure to report all changes to your vet. There are many cat health problems that can be readily treated to ease symptoms and pain for your cat.
It pays to remember that cats don’t like to share or queue. Sharing of ‘resources’ such as litter trays and foodbowls can cause stress and anxiety for many cats. It’s always a good idea to provide each cat with their own litter box, food, water bowls and bed as a minimum. One litter box for each cat plus a spare is even better, as are multiple sleeping spots and extra scratching posts. A lack of space to hide from or avoid other cats, competition for territory and lack of individual attention can also add to household friction. If your cat is feeling anxious, offering it an elevated place to sit, such as a climbing tree, can be helpful.
Moving to a new house, the arrival of a new baby, new pets and other types of change can seriously impact cat behaviour. Cats are creatures of habit and tend to be territorial, so a change in routine may cause them to react in a number of ways, including withdrawal or aggression. Try to keep your cat’s environment as calm as possible and make sure there are places where they feel safe. Sometimes confining them to a single room with a litter box, bedding and home comforts can help them to settle.
Some cats simply do not like being touched and handled. These are often cats that received limited socialisation with humans when they were kittens. These cats do best in a quiet household without children and need understanding and patience to help build their confidence.

Should Hand Feeding Dolphins Be Encouraged?
Some tourist centers train Indo-Pacific bottlenose dolphins to approach beachside public sighting areas or boats by hand-feeding them small amounts of fish every day. Because hand-fed males aggressively attack each other over the food, putting themselves and nearby humans in danger, tourist centers focus their hand feeding only on female dolphins, says Valerie Senigaglia at Murdoch University in Perth, Australia
But recent studies have shown that only 38% of the calves (崽) of hand-fed wild dolphins survive to three years of age, which is much lower than the average 77% survival rate for wild calves in general. To better understand why, Senigaglia and her colleagues evaluated the social behavior of dolphins around the Bunbury coast in Western Australia. In particular, they observed the individual behavior and movement of 35 dolphins, including 13 that had been hand-fed using a small boat. They regularly followed each dolphin for periods lasting from 20 minutes to 3 hours for two years in a row for a total of 180 hours.
They found that hand-fed dolphins swam in relatively large groups, but more readily broke away from them to join different ones. In general, they created weak ties with other group members. “You can feel lonely in a room full of people and it’s the same thing for dolphins,” says Senigaglia. Free-swimming dolphins that are fed by hand become less socially involved with their peers. As a result, their calves may grow up lacking vital social skills-which could explain, at least in part, why they are twice as likely to die before reaching adulthood as wild calves generally.
No wonder animal right activists are calling on the practice of hand-feeding dolphins to be stopped.

Cats Make for Ideal Human Companions
Cats have a reputation for being colder and less cuddly (令人想拥抱的) than their counterparts—dogs. In reality, they form close bonds with their owners and provide a sense of companionship, particularly for women. In fact, the findings of one Austrian study show that owning a cat is the emotional equivalent of being in a romantic relationship.
Some people feel silly talking to their pets, since, of course, they can’t respond. But interacting with your feline (猫科的) companions has proven health benefits. Not only does talking to your cat improve your bond, but it’s also said to be beneficial to your mental health by helping to improve your mood, lower your stress levels, and reduce our feelings of loneliness.
Cats are experts at sleeping, so it’s perhaps no surprise that they can help improve your sleep, too. A Mayo Clinic study found that people who slept with their pets in the same room were almost twice as likely to get a good night’s rest, with only 20 percent saying that they found their pets’ presence destructive.
Cats may not be able to help with the housekeeping, but they can assist in keeping your house free of mice. It turns out there’s some truth behind the cartoon cat-and-mouse chase. When mice smell certain proteins in cat saliva (唾液), they become tearful and therefore avoid the area.
It’s important for children to learn to care for and look after a living thing, just as their parents take care of them. Cats can help children develop social skills as they learn to approach the feline carefully and gently. Looking after a cat also encourages a sense of responsibility.
In addition to filling your heart with love, cats can contribute to keeping your heart healthy. Numerous studies have shown that owning a cat can help reduce your blood pressure and heart rate, as well as lowering your triglyceride (甘油三酸酯) and cholesterol levels, thereby reducing your risk of having a heart attack or stroke.

Does Recycling Work For Plastic?
Dealing with plastic waste is always a tough problem. According to the Organization for Economic Co-operation and Development (OECD), half of the world’s plastic waste ends up in a landfill, 19% burned, and another 22% escapes waste management systems and goes into uncontrolled dumpsites.
So environmentalists suggest plastic waste should be recycled properly, which proves an effective way to handle other waste like paper, cardboard, metal and glass. However, a new study by Greenpeace, and reporting in the Boston Globe, suggests that recycling plastic is a “myth” and raises a major question about the future: does recycling work? Unfortunately, the short answer is “not really.”
There’s been a lot of debate over what really happens to recycled plastic. But scientists say that recycling plastic waste has mostly failed because it’s very difficult to collect and nearly impossible to sort. Because plastic is often made from harmful materials, it can be harmful to the environment to reprocess.
Much of the solution falls on big companies to change the way they do business. The way forward seems to be mostly to cut down on companies’ reliance on plastic packaging, and to move toward reusable packaging and packaging-free alternatives. Above all, companies need to phase out all single-use plastics. For the consumer, living more plastic-free is the only real solution available. Avoiding drinks in plastic containers, using a travel mug or reusable water bottle, bringing your own reusable bag, buying in bulk and cutting back on pre-packaged foods are all a good start.
But in the end, corporate America needs a deeper commitment to the plastic waste problem. “Companies must take action now to get rid of single-use plastics and packaging and not rely on false solutions such as recycling,” says Greenpeace.

Kangaroos can “talk” to us
Kangaroos can “talk” to people, according to a new study. The report is the first research of its kind to be done on marsupials—a type of creature whose young get carried in skin pockets on their mother’s body. It suggests kangaroos are cleverer than previously thought.
Researchers from the University of Roehampton in the UK and the University of Sydney in Australia tested kangaroos at the Australian Reptile (爬行动物) Park, Wildlife Sydney Zoo and Kangaroo Protection Co-operative. The scientists put food in a box that the kangaroos could not open, and waited to see what the animals would do. Rather than giving up, 10 out of the 11 kangaroos actively looked at the person who had put the food in the box and then looked at the box. The researchers said this could be interpreted as the kangaroos requesting help to open the container.
Dr Alexandra Green, a co-author of the study, told The Guardian newspaper that some of the kangaroos actually approached the person and started scratching (挠) and sniffing (嗅) him, then looked back at the box. “So they were really trying to communicate,” Green said. This behaviour is not uncommon in animals. However, it is usually only seen in domesticated animals, such as pets or farm animals. The lead author of the study, Dr Alan McElligott, explained, “Through this study, we were able to see that communication between creatures can be learnt and that the behaviour of looking at humans to access food is not related to domestication. “Indeed, kangaroos showed a very similar pattern of behaviour we have seen in dogs, horses and even goats, when put to the same test,” he added.
It is hoped that the study will give people a more positive attitude towards kangaroos, which are sometimes seen as harmful creatures that damage farmers’ crops.

A plan to restore green spaces
The UK government has revealed a plan to protect and restore England’s wild life. It focuses on at-risk species by making canals, rivers and streams cleaner and expanding green spaces.
The new Environmental Improvement Plan sets goals to create or restore more than 5,000 square kilometres of wildlife habitats across England and restore 400 miles of rivers. It will create or expand 25 national nature reserves. New woodland will also be planted alongside rivers. At the moment, access to green spaces is not equal across the UK. Around 4% of people live more than 10 minutes away from their nearest park. The Environmental Improvement Plan aims to make sure households in England are within a 15-minute walk to a green space.
As well as helping more people to act close to nature, the plan should increase England’s biodiversity. A species Survival Fund will be set up to help some of England’s most endangered animals, such as red squirrels (松鼠) and watch rats. The Government has set targets to boost these species by 2030. There are also targets to reduce food waste, glass, metal, paper and plastic by 2028, and to improve the quality of water in rivers.
New rules mean that the Government will have to consider the environmental effects of any policy it puts forward. These goals are part of a 25- year plan that was launched in 2018. The aim of the plan is to improve the environment “within a generation ” which is roughly 25 years.
Although lots of people have welcomed the plan, not everyone is impressed. Pail de Zylva, from the charity Friends of the Earth, said it wasn’t clear enough how the goals would be met and that many of them were like promises the Government had already made but not yet delivered.
