1 . Light pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.
Artificial light at night can affect every aspect of insects' lives, the researchers said. "We strongly believe artificial light at night — in combination with habitat loss, chemical pollution.invasive (入侵的) species, and climate change — is driving insect declines, " the scientists concluded after assessing more than 150 studies.
Insect population collapses have been reported around the world, and the first global scientific review published in February, said widespread declines threatened to cause a "catastrophic collapse of nature's ecosystems".
There are thought to be millions of insect species, most still unknown to science, and about half are active at night. Those active in the day may also be disturbed by light at night when they are at rest.
The most familiar impact of light pollution is moths (飞蛾) flapping around a bulb, mistaking it for the moon. Some insects use the polarisation of light to find the water they need to breed, as light waves line up after reflecting from a smooth surface. But artificial light can scupper (使泡汤) this. Insects are important prey (猎物) for many species, but light pollution can tip the balance in favour of the predator if it traps insects around lights. Such increases in predation risk were likely to cause the rapid extinction of affected species, the researchers said.
The researchers said most human-caused threats to insects have analogues in nature, such as climate change and invasive species. But light pollution is particularly hard for insects to deal with.
However, unlike other drivers of decline, light pollution is relatively easy to prevent. Simply turning off lights that are not needed is the most obvious action, he said, while making lights motion-activated also cuts light pollution. Shading lights so only the area needed is lit up is important. It is the same with avoiding blue-white lights, which interfere with daily rhythms. LED lights also offer hope as they can be easily tuned to avoid harmful colours and flicker rates.

2 . It’s easy to assume that a vacation to Bali will cost a small fortune. There are plenty of accommodations, food and local transportation, and even the spas offer massages and treatments at value prices. However, you can easily spend a week or two in Bali for under $2,000, without having to sleep on the beach. Here are a few things to consider when planning Bali on a budget.
What is the best time to visit Bali on a budget?
If you’re on a budget, consider visiting Bali during the lower, wetter season, which runs from October through March. The crowds will be fewer, and both hotel rates and flights from abroad are often cheaper, except during the holiday period between mid-December and early January, when crowds swell. The only trade-off for the lower prices is the wet season. This time of year isn’t always ideal for sunbathing, and serious rainfall can make outdoor activities, such as whitewater rafting and visiting waterfalls and rice terraces, less than appealing. That said, even during rainy season, it doesn’t usually rain all day long. Expect bursts of sunshine between the storms.
What is the cheapest way to get around Bali?
The absolute cheapest way to get around Bali is by local bus, but it can take a long time. There are also tourist buses, including hop-on, hop-off options, that travel between different hubs across the island. Bali is well-served by taxis, both of the car and motorbike variety, and the prices tend to be affordable by international standards. Most drivers will offer you a fixed rate for full-day hires or to get from point A to point B, rather than using a meter.
Remember to bargain; doing so is particularly easy when a driver is on his own rather than at a taxi stand.
How much does food cost in Bali?
If you’re into fine dining, you can end up spending a large chunk of your budget on food. Eating at the average restaurant geared towards tourists is the best way to have a meal in Bali on a budget. A good meal should cost you around 100,000 rupiah (around $7), but if you’re willing to subsist mostly off of local specialties such as nasi goreng (fried rice) and eat at local restaurants, you can expect to pay around 30,000 rupiah ($2) to get fed. Best of all, most hotels and guesthouses in Bali come with free breakfast, and many offer heavier options of noodles and meat that may keep you full until lunch.
1. Which of the following situation can be best described by the underlined word trade-off in paragraph 2?| A．Jack got a reward after he returned the lost bag to its owner. |
| B．Lily spent much money buying some handicrafts at the local fair. |
| C．Wendy cancelled her trip in order to prevent the spread of the virus. |
| D．Sam was scolded by his parents for what he did in school last night. |
| A．It’s better for outdoor enthusiasts to visit Bali during the off season. |
| B．Passengers had better fix the price with drivers before the taxi pulls out from the station. |
| C．If on a tight budget, one is advised to visit Bali at the end of December every year. |
| D．It’s relatively economical to eat merely at average restaurants tailored to visitors. |
| A．City and Transport. | B．Travel and Recreation. |
| C．Nature and Environment. | D．Food and Health. |
3 . In a large survey of people's first memories, nearly 40% of participants reported a first memory that is likely to be fictional, according to findings published in Psychological Science, a journal of the Association for Psychological Science.
Current research indicates that people's earliest memories date from around 3 to 3. 5 years of age. However, the study from researchers at City, University of London, the University of Bradford, and Nottingham Trent University found that 38.6% of 6, 641 participants claimed to have memories from age 2 or younger, with 893 people claiming memories from age 1 or younger. This was particularly prevalent among middle-aged and older adults.
As many of these memories dated before the age of 2 and younger, the authors suggest that these fictional memories are based on remembered fragments(碎片) of early experience—such as a pram(婴儿车)，family relationships and feeling sad—and some facts or knowledge about their own infancy or childhood which may have been derived from photographs or family conversations.
“Further details may be unconsciously inferred or added, e. g. that one was wearing nappy when standing in the cot(幼儿床)," added Shazia Akhatr, first author on the study and Senior Research Associate at the University of Bradford.
“When we looked through the responses from participants we found that a lot of these first 'memories' were frequently related to infancy, and a typical example would be a memory based around a pram," explained Martin Conway, Director at the Centre for Memory and Law at City, University of London and coauthor of the paper.
“For this person, this type of memory could have resulted from someone saying something like 'mother and a large green pram'. The person then imagines what it would have looked like. Over time these fragments then become a memory and often the person will start to add things in such as a string of toys along the top," he added.
"Crucially, the person remembering them doesn't know this is fictional," Conway noted. "In fact when people are told that their memories are false they often don't believe it. This partly due to the fact that the systems that allow us to remember things are very complex, and it's not until we're 5 or 6 that we form adult-like memories due to the way that the brain develops and due to our maturing understanding of the world.
1. What does the underlined word "prevalent" in Paragraph 2 probably mean?| A．Unique. | B．Crazy. | C．Common. | D．Doubtful. |
| A．Some people have clear knowledge about their own infancy. |
| B．Added details are an important clue to recall the childhood. |
| C．Most people claimed to have memories from age 2 or younger. |
| D．Talks between family members influence the earliest memories. |
| A．By making comparison. | B．By setting examples. |
| C．By analyzing data. | D．By referring to documents. |
| A．Many people's earliest memories may be fictional. |
| B．People's earliest memories can date back to 2 or younger. |
| C．The middle-aged and adults specialize in detailing their first memory. |
| D．Memories develop due to our maturing understanding of the world. |
4 . Every year more people recognize that it is wrong to kill wildlife for “sport”. Progress in this direction is slow because shooting is not a sport for watching, and only those few who take par realize the cruelty and destruction.
The number of gunners, however, grows rapidly. Children too young to develop proper judgments through independent thought are led a long way away by their gunning parents. They are subjected to advertisements of gun producers who describe shooting as good for their health and gun-carrying as a way of putting redder blood in the veins（血管）. They are persuaded by gunner magazines with stories honoring the chase and the kill. In school they view motion pictures which are supposedly meant to teach them how to deal with arms safely but which are actually designed to stimulate（刺激）a desire to own a gun.
Wildlife is disappearing because of shooting and because of the loss of wildland habitat Habitatloss will continue with our increasing population, but can we slow the loss of wildlife caused by shooting? There doesn't seem to be any chance if the serious condition of our birds is not improved. Wildlife belongs to everyone and not to the gunners alone. Although most people do not shoot, they seem to forgive shooting for sport because they know little or nothing about it. The only answer, then, is to bring the truth about sport shooting to the great majority of people.
Now, it is time to realize that animals have the same right to life as we do and that there is nothing fair or right about a person with a gun shooting the harmless and beautiful creatures. The gunners like to describe what they do as character-building, but we know that to wound an animal and watch it go through the agony of mortality can make nobody happy. If, as they would have you believe, gun-carrying and killing improve human character, then perhaps we should encourage war.
1. According to the text, most people do not seem to be against hunting because .| A．they have little knowledge of it. |
| B．it helps to build human character. |
| C．it is too costly to stop killing wildlife. |
| D．they want to keep wildlife under control. |

| A．teach them how to deal with guns safely. |
| B．praise hunting as character building. |
| C．describe hunting as a physical exercise. |
| D．encourage them to have guns of their own. |
| A．Hunting to build human character makes no sense. |
| B．War in the best way to improve human character. |
| C．We are on the edge of war against gunners. |
| D．Protecting wildlife from gunners is extremely difficult. |
5 . The COVID-19 pandemic is having a negative influence on people with eating disorders, according to a new study from the UK.
While it is well known that COVID-19 is having a great effect on the global population, a research carried out by researchers from Northumbria University shows that the pandemic raises additional, unique challenges for individuals with eating disorders.
During the early stages of the UK pandemic lockdown, Dr. Dawn Branley-Bell and Dr. Catherine Talbot surveyed individuals across the country who are now experiencing, or in recovery from, an eating disorder.
The results suggest the disruption (扰乱) to daily life as a result of being locked at home and social distancing may have a detrimental influence on an individual’s well-being, with almost nine out of ten participants reporting that their symptoms had worsened as a result of the pandemic.
Detrimental impacts on psychological well-being include decreased feelings of control, increased feelings of social isolation (孤立), and low feelings of social support, the survey discovered.
Through an analysis of participants’ responses, researchers found the negative effects maybe due to changes in a number of factors, including regular routines, living situations, time spent with friends and family, access to treatment, engagement in physical activity, relationship with food, and the use of technology.
The research team warns that the effects of not being able to access professional eating disorder treatment during the pandemic could be severe, causing some people’s conditions to become much worse and—in some cases—could prove deadly.
“Our findings stress that we must not underestimate the impact of the pandemic,” Branley-Bell said, “Individuals with eating disorders will likely experience a long-tern effect on their symptoms and recovery. It is important that this is recognized by health care services, and beyond, in order to offer the necessary resources to support this population.”
1. The underlined word “detrimental” in the fourth paragraph probably means ________.| A．embarrassing | B．damaging |
| C．beneficial | D．professional |
| A．health care services are important for helping those with eating disorders |
| B．the lack of regular routines is the main factor for the negative effects of the pandemic |
| C．having access to medical treatment can improve people’s conditions immediately |
| D．individuals with eating disorders have an increased sense of control due to the pandemic |
| A．The deep influence of the pandemic on the worldwide population. |
| B．The serious effects of the changed time spent with friends and family. |
| C．The harmful effects of the pandemic on citizens with eating disorders. |
| D．The importance of the necessary resources provided by health care services. |
6 . From my kitchen windows, I watch colorful birds responding for black-oiled sunflower seeds, split peanuts, and cut grapes and apples on the ground. The scene is delightful and calming.
About three years ago, I noticed a newcomer to this colorful and happy display. It was a baby chipmunk（花栗鼠）, obviously on its own. Over that summer, I watched it grow. The brown and black stripes（条状）on its back darkened. The next summer, it was back, and I wondered whether it would trust me to feed it by hand or let me pet it. I decided to employ the tricks I used to persuade wild cats to come close for food: patience, a soft voice, slow moves and repetition. Before it would approach, I’d put down its favorite food--sunflower seeds, bend over and keep very still. I’d leave my open hand in place, unmoving, so the animal would know I wouldn’t seize it. I continued doing this for a few weeks. Finally, late in that second summer, it did show more trust. One day as I offered a seed on my fingertips, it approached and carefully took the seed into its mouth. It never bit my fingers. I was elated that we had made a breakthrough of trust. After about two months of this routine, I went further. With one finger, I petted its back once, but it didn’t move away. I then petted with two fingers. Again, it stayed put, eating seeds.
Today, the Chipmunk comes out of hiding when I call its name, and lets me pet its soft, silky body. Whenever I am doing this, I feel calmer. To my surprise, I also feel a sense of greater respect for nature and its creatures and the opportunity to observe, protect and save wildlife. Most of all, I’ve saved the wonderful memories gathered during these glorious summer months in my Long Island garden.
1. What did the writer do before the Chipmunk trusted him enough to get closer?| A．Petted its back. | B．Offered it food. |
| C．Called its name. | D．Watched it play |
| A．disappointed | B．excited |
| C．frightened | D．puzzled |
| A．A furry friend and a bond of trust | B．A lovely animal and an adventure |
| C．A stress reliever and a calm mind | D．A newcomer and its protection |
7 . A group of second-year college students have discovered hidden writing on a page from a book from the 1500s, using a special camera system they built.
Surprisingly, finding hidden writing on very old documents isn’t all that unusual. In fact, there’s even a special name for documents like this: a palimpsest (再生羊皮纸卷).
Long ago, writing was done on parchment — thin, dried animal skins specially prepared for writing. But parchment wasn’t easy to make and wasn’t cheap. So it became common to erase the old writing off a parchment and then reuse it for another piece of writing. That’s what creates a palimpsest.
The writing erased off the parchment can’t be seen directly, but scientists have learned ways to use special lighting to reveal the original writing. But it’s unusual for young college students to discover palimpsests.
Last year, first-year students at the Rochester Institute of Technology took part in a class that brought together many students to take on a project as a group. The project was to build a special camera system that could take pictures using different kinds of light.
Over the summer, the students working on the imaging camera managed to finish it. When they were done, they borrowed several old parchments from the collection at the school’s Cary Graphic Arts Collection. When they put one of the pages under their camera system with UV light, the hidden writing suddenly appeared. Under the UV light, handwriting in French could easily be seen behind the fancy writing and decorations normally visible on the page.
Zoe, a student involved in the project, said, “This was amazing because this document has been in the Cary Collection for almost 10 years and no one noticed it.” The students are even more excited because even though the parchment is no longer part of a book, they know where 29 other pages from the same book are. The students, who are now working with others to locate the other parchments, hope these, too, will have hidden writing and that they can figure out what it means.

8 . From the moment you arrive at Houtong Village in northern Taiwan, you’ll have no trouble knowing who the real stars are. There’s a cat-shaped bridge, pet food bowls on the side of the walkways, street signs with cat pictures, cat-themed cafes and, of course, furry friends wandering freely everywhere.
In the early 1900s, Houtong, in New Taipei City, was the biggest and most technologically advanced coal-mining site in Taiwan. It was a prosperous town with about 6,000 residents and workers, before the mine fell into disuse in 1990.
As most young residents moved away for better opportunities, Houtong became a sleepy village with about 100 residents. But in 2010, Houtong gained popularity after a cat-lover and photographer started blogging about the village’s growing stray (无主的) cat population.
Houtong was transformed into a cat-lover sight while also providing a source of income for local villagers. Many of the stray cats, now given affectionate nicknames, are taken care of by local villagers as well as a troop of volunteers.
In addition to the village’s many cute kitty-themed shops and cafes, the local government has also seized the opportunity to highlight its long history.
An award-winning pedestrian cat bridge was built. A cat information and education center opened in 2014, featuring higher cat walkways in front of the building. A museum park dedicated to the town’s former mining life opened in 2010, later hosting a cat lantern festival in 2012.
But Houtong, now under the spotlight, isn’t completely perfect. According to local reports, the town has become an attraction for those looking for a place to abandon their unwanted pets. During the most recent survey, it was estimated that the village is now home to about 286 cats—50 heads more than two years ago.
With the constant patting and feeding from visitors, some also flagged concerns about the health of the furry residents. The department works with local residents and volunteers to vaccinate (接种疫苗) the cats and provide regular medical treatment. Signs have been set up around town advising visitors how to behave while also pleading for the pet owners’ responsibility.
1. Why does Houtong become popular recently?| A．Because it is a town with the biggest coal-mining site. |
| B．Because it is a town with a long history. |
| C．Because it is a town where the mine falls into disuse. |
| D．Because it is a town featuring cats culture. |
| A．Young residents moved far away for better opportunities. |
| B．The development of the village cannot meet the demands. |
| C．There are not enough volunteers in the village. |
| D．The cats are not in good health condition. |
| A．Applying. | B．Begging. |
| C．Fighting. | D．Registering. |
9 . As online technology advanced, web sites, podcasts, and blogs became powerful sources of information that allowed everyone to stay updated on any subject imaginable. Although all of these information sources remain popular, there's a new king of media and it's online video.
There are many reasons why online video has increased suddenly over the past few years. The first is increasing data speeds. It wasn't until recently that people everywhere had fast enough online connections to enjoy high-definition （高清）videos. However, once faster Internet speeds were provided, people quickly fell in love with online videos. The second reason why online videos have become so popular is convenience. Watching videos requires less effort and energy than reading through paragraphs of text after a day of hard work. Videos also seem to provide more satisfaction, as people prefer to connect with people they can hear and see, as against the words of some author whom they know little about.
Advancing digital technology has also helped, as it has made sharing videos easier and more convenient than ever. High-powered smartphones and more affordable video cameras allow anyone to easily record an event or give a few comments about a scorching topic that is on their mind. Meanwhile, sites like YouTube, Vimeo, and Ustream allow users to quickly upload their videos and share them with friends, family, and the general public if they wish.
Last but not least, advertising. Companies have made it easy for people to get rewarded for creating popular videos. Some people with large enough fan bases can even make a very wealthy living by uploading a few videos every week.
The future also looks bright for companies who post online video ads. In fact, new software allows them to watch viewers' emotional reactions to their content through the users' webcams （网络摄像机）.They'll be able to see whether users laugh, cry, or feel bored during videos, so they can adjust their ads. This should prove extremely helpful, as there will be millions of videos competing for viewers' attention.
1. Why do some people prefer watching videos to reading after work?| A．It helps them review the news. |
| B．It helps them get information with relative ease. |
| C．It provides them more information. |
| D．It helps them save time. |

| A．It will enable them to better understand what customers enjoy. |
| B．It will let more viewers see the advertisements they make. |
| C．It will cause viewers to create more popular videos. |
| D．It will make people like their videos. |
| A．Online Video: The New King of Media |
| B．Online Technology is Developing Fast |
| C．Online Video: A New Advertising Trend |
| D．Online Technology is Closely Related to People |
10 . I was given a voice. That’s what people said about me I trained my voice, because it would be a shame to waste such a gift. I pictured this voice as a greenhouse plant and made sure it was provided with the right temperature, the right amount of water. I relieved its fears. I told it not to tremble. I nursed it, I trained it, and I watched it climb up inside my neck
My voice bloomed. People said I had grown into my voice. Invitations to perform flooded over us. All the best places wanted us. I was sought after, or rather my voice was. We went everywhere together and gave performances. Bouquets （花束）were thrown to it. Money was presented to it. Men fell on their knees before it. Applause flew around it.
Then my voice began to shrivel. People said my voice would bloom only for a certain term: finally it would drop off and gone with it would be all the fame and wealth. I have noticed it so far. Fear has entered me since my voice has used up most of my life. I’ve given it all my love. But my voice is still as greedy as ever. It wants more: more and more, more of everything it has had so far.
Now it’s evening: the bright lights come on, and excitement quickens in the streets. We sit in this hotel room. Soon it will be time for us to go out. We have to attend a grand occasion. The two of us chained together as always. I have to put on its favourite dress, its favourite necklace and wind a fur around it. Then I have to go out: shining like ice: my voice attached to my throat like an invisible vampire （吸血鬼）.
