2 . Akira Toriyama, one of Japan’s leading comics authors, whose manga (漫画) “Dragon Ball” achieved worldwide success with its mix of comedic characters and electrifying martial arts battles, died on March 1. Mr. Toriyama’s body of work, which also includes “Dr. Slump” and “Sand Land,” has influenced generations of manga artists and cartoonists.

His best-known work, “Dragon Ball,” follows a young boy named Son Goku who embarks on a journey to collect the seven magical balls that summon a wish-granting dragon. Since its creation in. the 1980s, it has sold millions of copies worldwide and become one of the most famous manga.

Throughout his career, Mr. Toriyama said in a 2013 interview with the Japanese newspaper The Asahi Shimbun, he did not care if his work did anything besides entertaining its readers. He was, he suggested, unlike “other manga artists concerned about conveying educational messages.” “The role of my manga,” he said, “is to be a work of entertainment through and through.”

When “Dragon Ball” was first published in 1984, it was an immediate hit. “Dragon Ball” was serialized in the Japanese magazine Weekly Shonen Jump until 1995. In the year after the series ended, the magazine lost about one million of its six million readers.

As a productive manga artist, Mr. Toriyama did not necessarily have an appetite for the genre as a reader. “I have always had a hard time reading manga, including my own work,” he said in a 2018 interview. He led a private life and gave few interviews. In a 2013 interview with the Japanese singer and actress Shoko Nakagawa, he said that he did not even share all his work with his family.

“To tell you the truth, no one in my family has ever seen ‘Dragon Ball,’” he said, laughing. “I am also a hikikomori,” he added, using the Japanese word for a loner.

3 . Life is often marked by unexpected twists and tums. As Alice and Mike watched their son Allan ______ Cambridge University Law School last month, they thought back to the moment he was born. “I’m so sorry your baby is blind,” a nurse had said.

Even though Allan’s family were middle class and they lived a ______ life, as a blind child, Allan Hennessy’s future was poor. The local hospitals could not offer Allan hope of giving him ______ because there weren’t enough eye specialists. But when Allan was 6 months old, an opportunity came and Allan’s father ______ it. “My dad sold his car, belongings and some of his land to pay for my ______. We left our home country with very little.”

The opportunity was an operation in London which ______ the sight in Allan’s left eye. “My mom remembers the first time I looked at her; the first time we made eye ______. She burst into tears. But for the operation, I wouldn’t have ______ anything in life,” he. explained.

For Allan, life as an immigrant (移民) was ______. When he was ___into Cambridge University, Allan realized there were so many differences between him and his peers (同龄人) at Cambridge. “I felt ______ different,” he said. “When you’re a half-blind guy climbing the greasy pole, everyone can see that and they judge you, even though they are ______ it too.”

But spending three years in Cambridge was ______. Allan said, “I met the most amazing people from all over the world.” What would his life be like if he had stayed in his home country? “I wouldn’t have a Cambridge law ______; I wouldn’t even be sighted. My family there have faced terrible events. Perhaps I wouldn’t be alive.”

After graduating this summer, Allan is taking up a scholarship and ready for being a graduate school student. “If you’ve got a first-class law degree from Cambridge University, that should set you up for life,” he said. “But when you’re a half-blind immigrant living in Britain today, there is so much more you have to do. The ______ has only just begun.”

4 . When I was three, I had a very good friend named Gemma. She was fearless where I was anxious, rebellious where I was conservative, and _________ where I was awkward. She was also entirely imaginary. With Gemma’s support, I almost made it to the top shelf of the bookcase before my parents found me — and “Gemma said it was fine!” did not _________ me from a telling-off (责骂).

I cannot remember when or how I “met” Gemma, and, perhaps sadder still, I do not remember the _________ time I “saw” her. _________ my brain created her, she inspired me to go on adventures I would not have had the confidence to embark upon without her. It _________ me, then, that 72 percent of nursery workers believe children have fewer imaginary friends than they did five years ago, as is shown by a recent survey. This is believed to be a result of _________ screen time.

It is thought that 40 percent of us at one time or another had imaginary friends during our _________. In an essay for Aeon, writer Sophie Elmhirst found that 81 percent of those surveyed had “lost” their imaginary friends after they turned ten, but most of these friendships ended _________. Perhaps imaginary friends simply stay with us for as long as we need them. They move on when our lives become too _________ for our brains to make space to generate their own entertainment.

If you have enjoyed an imaginary friendship, I would guess that you did not __________ sit down to create a perfect pal. They probably arrived as an indication of the thoughts and ideas you never knew you had. In order to be a good __________ to an imaginary friend, you need to be able to make “what if?” into an exciting proposition. When we grow up, we are too quick to finish the sentence with “what if it goes wrong?”

Having grown up, we might not need our imaginary friends anymore, but we could still use a reminder that a little bit of boredom is good for us, and that our brains can create the best ideas when they are left to their own devices. If there are fewer imaginary friends __________ the worlds where our children live, that might lead to a future with fewer artists, writers and problem-solvers. This is a real cause for __________.

As an adult, I think of my fearless, invisible friend Gemma whenever I have to do something that __________ me — usually public speaking, rather than scaling a bookcase. However, whenever I __________ my own expectations and meet myself in a place that I did not think I could quite reach, I can hear my subconscious whispering, “Gemma made me do it.”

5 . When continent splits occur, they usually leave traces in ancient rocks, fossils, and mountain ranges. However, around 155 million years ago, when a 5,000-kilometer land broke away from Western Australia and began its drift, it only left behind a basin deep below the ocean known as the Argo Abyssal Plain and scientists have been unable to find where this lost continent, Argoland, disappeared to until now.

The seabed structure suggests that the continent drifted northwestward, potentially towards present-day Southeast Asia. But surprisingly, there is no large continent hidden beneath those islands, only small continental fragments. Using this theory, geologists discovered that Argoland hadn’t really disappeared but survived as a “very extended and fragmented collection” under the islands to the east of Indonesia. Unlike other continents like Africa and South America, which broke neatly into two pieces, Argoland split into many smaller fragments that were dispersed (分散的). With advanced technology and the discovery, scientists can now piece them together.

Tracing the continents is vital for understanding processes like the evolution of biodiversity. It could help explain something known as the mysterious Wallace Line, which is an imaginary boundary that separates mammals, birds, and even early human species in Southeast Asian islands. The boundary has puzzled scientists for long because it clearly separates the island’s wildlife. To the west of the line are mammals like apes and elephants. But these are almost completely absent to the east, where you can find marsupials and cockatoos — animals typically associated with Australia. Researchers have theorized that this may be because Argoland carried its own wildlife away from Australia before it crashed into Southeast Asia, which helps explain why different species are found on one land.

The story of Argoland is not one of complete disappearance but of transformation. As the world continues to evolve, this lost continent serves as a powerful symbol of the fragility (脆弱性) of life on this planet, and a reminder of the importance of respecting and protecting the world that we live in.

8 . The prevalence (普遍) of sweatshop (血汗工厂) labor depends largely on the definition being used. At its most _______ definition, the term refers to work in a confined space (small, surrounded by walls) that is extremely difficult or dangerous. Sweatshops are considered to be fairly common. If the definition being used is closely related to the commonly-held _________ of a factory with overworked, under-paid workers, sweatshop labor becomes less common than expected. _________, they are still prevalent in third-world countries. According to the United States Government Accountability Office, a sweatshop is any workplace that breaks one or more state and federal _________ laws. Experts believe that roughly 50 percent of manufacturers—_________ in the clothing industry — employ sweatshop labor.

It can be _________ to figure out the exact number of sweatshops in a particular area. These workplaces usually, if not always, violate labor laws. Violations can include workers being paid less than minimum wage, child labor, and the severe lack of safety regulations. _________, many of these locations tend to hide their identities as sweatshops through a number of different means. For example, they might bribe government officials.

Another factor that _________ the prevalence of sweatshop labor is the economic situation in the country or region. Many individuals choose to work in sweatshops simply because there are no better alternatives _________ livelihood (生计), even if the income they’re being given still cannot support their basic standards of living. This has led to a sharper increase in sweatshops in third-world economies. In these countries, there is a __________ advantage to working in a sweatshop rather than not working at all. __________, the large number of people willing to work under such conditions causes employers to run more sweatshops.

Certain economists argue against the popular opinion that sweatshop labor should be considered __________. Sweatshop supporters argue that the workplaces are a necessity for poor countries. Sweatshop workers actually earn more than average in those countries. Following this train of thought, sweatshops are looked upon as an economic stimulus (刺激物). Employers following this belief are __________ to increase the number of sweatshops in poorer countries.

However, other experts think that __________ labor standards in third-world countries creates a downward spiral (螺旋线). That is to say, people will be forced to accept working in increasingly worsening circumstances. The demand for work is significantly larger than the number of jobs that are available. It’s quite __________ for wages and employee rights to continue going downwards in response to such desperation. As a result of the economic circumstances in a given region, employers who follow this philosophy are quick to point out that their businesses do not fall under the definition of a sweatshop.
