1 . Nobody wants to snack on plastic bags or soda rings, but according to a recent study from the University of Neweastle, we could be consuming roughly a credit card's worth of plastic every week.
Microplastic, which are less than a quarter-inch size and come in various shapes, have polluted the natural world and infiltrated(渗入)our bodies. The first clue to microplastic exposure in humans came around 2013, when scientists discovered plastic particles in seafood prepared for consumption. But in 2019, when the University of Newcastle study was published, the scientific community understood that the problem was considerably broader. Microplastics shed off clothes and tires and have been found in beer, honey, table salt and other food items. We breathe in plastic staying in the air and drink plastic floating in our drinks. It's no stretch to conclude that our exposure is significant. What we don't know is what this means for us.
The amount of evidence collected on this subject is growing rapidly, according to Scott Coffin, a toxicologist(毒理学家). Studies done on mice and rats have found that plastic in their bodies can severely damage cells and cause stress.
Because microplastics are too small to clean up, the only solution is to stop plastic waste at the source. And doing so would take a thorough adjustment, given that plastics are deeply embedded in our economy and lifestyle. Stopping using them would fundamentally affect countless industries, including textiles(纺织业), transportation and manufacturing.
"I think we need to have more studies coming out that are directly related to human health before we see a lot more concern from the general public," Scott said. "It takes a lot to convince people that something that is really convenient for them to use is something they should sacrifice."
The question of microplastics and human health needs more attention—from the scientific community ,the general public, the government and funding groups. The issue isn't being ignored, but it's not being prioritized either.

2 . Every year on April 22,Earth Day marks the anniversary of the birth of the modern environmental movement in 1970.It gave a voice to an emerging public consciousness about the state of our planet.The founder was Gaylord Nelson.
What moved Gaylord Nelson to action was the1969massive oil spill（溢出）in California,the largest oil spill in the United States at that time.The spill proved to be an environmental nightmare as it had a strong impact on marine life,killing an estimated3,500sea birds,as well as marine animals such as dolphins,elephant seals and sea lions.Inspired by the student antiwar movement at that period of time,Nelson found it was a right time to channel the energy of the students towards a fight for environmental protection.He decided that it was time to educate the Americans on the need to protect the environment.Thus,Earth Day was born in1970,and public environmental consciousness took centre stage.
On 22nd April 1970,millions of Americans took to the streets to demonstrate for a healthy,sustainable environment and thousands of students marched in protest of the terrible situation of the environment.Businesses were forced to follow environmental standards if they wanted to continue their operations.The year1990 saw Earth Day reach out to many more countries around the world.It helped pave the way for the 1992 United Nations Earth Summit in Rio de Janeiro,bringing together many nations,for a joint effort towards protecting the environment.In 2009,the United Nations decided to officially set April 22 as Earth Day.
For his role as founder of Earth Day,Gaylord Nelson was awarded the Presidential Medal of Freedom（1995）,the highest honour given to civilians in the United States.We honor the man,as the fight for a cleaner environment continues.

5 . The convenience plastic offers has led to a throw-away culture that reveals the material’s dark side. Many of its products, such as plastic bags and food wrappers, have a service life of mere minutes to hours.
Plastic has been the biggest threat to ocean life for decades. Sunlight, wind and wave action break down plastic waste to a certain extent, but it only succeeds in reducing it to smaller pieces.
Tests have also confirmed cell damage and trouble with animals’ reproductive systems caused by plastic-eating. Some species, such as oysters, produce fewer eggs if they wrongly take too much plastic.
Fortunately, solutions are being found. Many scientists agree the top priority is to prevent plastic waste from entering rivers and seas.
| A．Nearly every species of seabird eats plastics. |
| B．This makes plastic waste even harder to notice. |
| C．Millions of animals are killed by plastic every year. |
| D．Some pieces have even been found blocking their organs. |
| E．Half of all plastics ever produced have been made in the last 15 years. |
| F．It could be done with improved waste management systems and recycling. |
| G．However, they may remain in the environment for hundreds of years and cause a lot of harm. |
6 . Understanding the link between a clean environment and human life is not a new concept. In fact, it was noticed as early as ancient Rome. Today we see how green living has infiluenced our everyday lives. There is a growing community of people who embrace a zero waste lifestyle and make changes to the way they live to reduce their carbon footprint.
Living a zero waste lifestyle means doing one’s best to achieve the aim of not sending anything to a landfill. People who adopt this lifestyle ultimately cut down on their waste by reducing what they need and want. They reuse what they own, sending few things to be recycled.
Many people who adopt the zero waste lifestyle claim to be frustrated by the many harmful chemical substances found in beauty and cleaning products. They also find the uses of disposable items and excessive packaging. For example, how many times have we had to peel away layers of plastic wrap and cardboard before finally taking out the item which we had bought? Instead of buying pre-packed food and goods, those who identify with the zero waste philosophy tend to shop in stores that allow them to make purchases and bring their own cloth bags and glass jars to store their purchases.
Many people may have the misconception that it is easier to live a zero waste lifestyle in the West. Nevertheless, Malaysian environmental journalist, Ms. Aurora Tin, has proven that a zero waste lifestyle is possible even in the Asian context. Instead of going to the supermarket to buy pre-packaged foods, Ms. Tin now visits the wet market and brings her own bags for vegetables. She has even stopped using store-bought toothpaste and makes her own toothpaste from coconut oil and baking soda. This lifestyle may be too big a change for the average person, but we could follow her suit to make gradual changes to our own lives.
1. Which of the following is a zero waste lifestyle?| A．Bringing a resuable container to take away food. | B．Choosing appliances that cost less money. |
| C．Turning off a device to stop using power. | D．Classifying the garbage before throwing it away. |

7 . A lunch break – it’s an important and often necessary part of our working or school day. And now we’re spoilt (惯坏) with a lot of places to buy our lunch from, all offering attractive dishes and sandwiches to eat on the go.
But our appetite for buying our lunchtime fare is not just costing us money, there might be a cost in terms of damaging our planet too. Just grabbing a sandwich, crisps and maybe a cake and coffee can produce at least four items of waste. Paper boxes, cups, wrappers and plastic knives and forks are all part of our disposable (一次性的) feast in addition to the food waste we create. Some experts say throwing away food, which produces methane (甲烷) as it rots, is a bigger cause of climate change than plastics.
But regardless of what causes the most damage, the solution, according to an environmental campaign group called Hubbub, is to eat packed lunches. Tessa Tricks from the group says “People are saying that they are buying food to take out because life has got busier.” And she says people think they are being more efficient; but she argues that it's usually healthier and cheaper to make your own lunch. It means you can eat the things you really want and make the quantity that you actually need.
Of course, preparing your lunch is another thing to fit into your morning scramble (忙乱) of getting ready for work, so if you haven’t got time and you are going to buy lunch, an alternative that Hubbub suggests is to take your own container to a shop and ask them to put your food in it. The idea of using reusable coffee cups for hot drinks and refilling water bottles has already proved successful, so this could be another step in the right direction.

8 . Masks that helped save lives are proving a deadly danger for wildlife, with birds and sea creatures trapped in the shocking number of thrown-away facial coverings. Single-use masks have been found around pavements, waterways and beaches worldwide. Worn once, the thin protective materials can take hundreds of years to decompose. “Face masks aren't going away any time soon—but when we throw them away, these items can harm the environment and the animals,” Ashley Fruno of animal rights group PETA said.
In Britain, a gull was rescued by the RSPCA after its legs became tangled in the straps of a mask for up to a week. The animal welfare charity took it to a wildlife hospital for treatment before its release.
The biggest impact may be in the water. More than 1.5 billion masks made their way into the world's oceans last year, accounting for around 6,200 extra tonnes of ocean plastic pollution, according to environmental group Oceans Asia.
Conservationists in Brazil found one mask inside the stomach of a penguin after its body was washed up on a beach, while a dead pufferfish was discovered caught inside another off the coast of Miami. French campaigners found a dead crab trapped in a mask near the Mediterranean. Masks and gloves are “particularly problematic” for sea creatures, says George Leonard, chief scientist from NGO Ocean Conservancy. “When those plastics break down in the environment, they then enter the food chain and impact entire ecosystems.” he added.
There has been a shift towards greater use of reusable cloth masks as the pandemic has worn on, but many are still using the lighter single-use varieties. Campaigners have urged people to bin them properly and cut the straps to reduce the risk of animals becoming trapped. Oceans Asia has also called on governments to increase fines for littering and encourage the use of washable masks.

9 . Beginning 2020, the fifth generation of wireless technology is expected to be widely used throughout the world. The new network, called 5G, promises to give faster speeds and a higher capacity for the use of more devices. However, while some companies are competing to be the first to deliver 5G to the consumer, the environmental influences of the new network are being overlooked.
There is some evidence that the new devices and technologies associated with 5G will be harmful to ecosystems. The main component of the 5G network that will affect the earth's ecosystems is the millimeter waves. The millimeter waves that are being used in developing the 5G network have never been used at such scale(规模)before. Studies have found that there are some harms caused by these new technologies.
The millimeter waves, specifically, had a detrimental effect on birds. In a study, researchers observed that after exposure to radiation from a cell tower for just 5~30 minutes, the eggs of sparrows were disfigured. The disfiguration of birds exposed for such a short amount of time to these frequencies(频率)is significant considering that the new 5G network will have a much higher density(浓度)of base stations(small cells) throughout areas needing connection. The potential dangers of having so many small cells all over areas where birds live could threaten their population's survival.
Additionally, it was found that cellular devices were linked to many disturbances in the ecosystems of bees. In this study, beehives exposed for just ten minutes to 900MHz waves fell victim to colony collapse disorder(蜂群崩坏症候群). Bees are an incredibly important part of the earth's ecosystem. Around one-third of the food produced today is dependent on bees for pollination(授粉), making bees are a vital part of the agricultural system.
The impact that the cell towers have on birds and bees is important to understand, because all ecosystems of the earth are interconnected. If one component of an ecosystem is disrupted the whole system will be affected.
1. What will probably cause the environmental problems with the wide use of 5G network?| A．The lack of the density of base stations. |
| B．The less mature devices and technologies. |

10 . In the past five years, about 2.8 billion of school textbooks were sold per year, with total spending of 20 billion yuan ($3 billion), news magazine Outlook Weekly reported, citing data released recently by the National Press and Publication Administration.
If these textbooks are reused for one year, the costs saved can be used to help build around 40,000 Hope Schools in impoverished regions.
The figures show that in 2018, the number of retailed textbooks for primary and secondary schools was 2.93 billion copies, totaling 25.99 billion yuan. If all of them are reused, a total of over 20 billion yuan will be saved per year.
Zhao Dehua, in charge of a company recycling resources, said many college graduates sell the textbooks they have accumulated over the years at an average price of 1 yuan per kilogram. As these textbooks are mostly used to produce recycled paper, the cost is even higher than that of raw paper as the processing procedure of recycled paper is complicated.
At present, free textbooks related to music, art and P.E for the nine-year compulsory education have been reused, but account for less than a fraction of the total number of textbooks. Because of the supply chain obstruction, which increases the costs to match supply with demand, the lack of sound platform and service supporting system for the second-hand textbook trade, most of the textbooks used for compulsory education and higher education end up as waste.
“Every year, second-hand booksellers collect textbooks at a price of about 4,000 yuan a ton, which is more than twice the price of ordinary waste paper, but the number of people who come to collect second-hand books is still few,” Zhao Dehua said.
Besides, the incomplete policies and regulations might bring second-hand book sales platforms and sellers to legal risks.
“Establishing the system of textbook recycling can not only save resources, but also help to cultivate students’ consciousness and sense of responsibility,” said Zhu Pin, deputy head of a school of nine-year compulsory education in Jiangxi province. The school has set up a system for reusing the textbooks and the books are disinfected every week.
1. What can we learn from paragraph 4?| A．College students sell textbooks in order to make profits. |
| B．Recycled paper is mainly used for environmental considerations. |
| C．The cost of recycled paper is greater than that of raw paper. |
| D．Certain groups of collectors tend to choose second-hand textbooks. |
