1 . Nuclear pollution is a serious global   ___________, brought to the forefront by major accidents at Three Mile Island, Chernobyl, and Fukushima. These events have demonstrated the significant health and environmental risks _________by nuclear disasters. Not only have they caused immediate health problems, such as radiation sickness and increased cancer rates, but they have also _________lasting environmental damage and genetic changes in affected communities. As a result, nuclear pollution remains a pressing concern for governments, scholars, and individuals worldwide.

When nuclear accidents occur in coastal areas, the _________environment becomes a critical concern due to the crucial role that oceans play in _________the climate, ensuring food security, and supporting the livelihoods of billions of people globally. In recent years, the increasing threats to marine ecosystems from ocean pollution have _________public awareness of the need to protect the marine environment. Studies have shown that human activities pose a _________threat to marine environments, emphasizing the importance of improving environmental management and taking measures to mitigate environmental risks.

Following the Fukushima nuclear disaster in 2011, efforts to cool the reactors by pumping in seawater resulted in the _________of a significant amount of nuclear waste in the water storage tank at the Fukushima Nuclear Power Plant. _________attempts to manage this waste, the Japanese government’s decision to release nearly 1.26 million tons of nuclear wastewater into the Pacific Ocean over the next 40 years has faced opposition __________neighboring countries, local ____________, and international environmental organizations.

This __________poses serious risks to marine life, fisheries, and human health. Radioactive isotopes present in the wastewater, such as tritium, carbon-14, cobalt-60, and strontium-90, can accumulate in marine organisms and ultimately affect human populations through the food ____________. Therefore, there is an/a ____________need for further research and mitigation measures to __________the widespread impacts of nuclear pollution on the environment and human health.

2 . Last year I attended the annual autumn saffron (藏红花) harvest festival on a trip in Italy, known as the sagra. Giovannina Sarra and her family ________ me at their home. Early the next morning, we ________ among the fields and participated in the harvest.

Saffron , taken from the stigmas (柱头) of the saffron flower, is a(n) ________ crop. Also called red gold, it is a(n) ________ from Spain, first introduced into the region around the 13th century. Saffron is ________ in the hours just before ________, while the petals (花瓣) are closed. This helps protect their precious stigmas and makes the flowers easier to ________, especially preferred by the acquirers (收购商). Later, on the same day, the stigmas — three ________ strings per flower — are separated from the petals. It’s a delicate ________ that takes hours with a skilled and ________ hand. In the evening, over an open wood fire, the stringlike stigmas are ________ to make saffron powder to add to the richness of the color and the flavor, which brings considerable income.

Now sitting at a mouth-watering plate of Risotto alla Milanese, a dish cooked with saffron, I ________ the freezing morning with Sarra and her family. There’s no ________ that it is the families like the Sarras that stick to the many ________ that have survived from generation to generation. ________ more people will join them.

3 . Even when you have confidence in yourself, your goals will sometimes seem out of reach. When that happens, get hold of the people who _________ you and your goals and don’t let go!

When I was younger, I _________ because life felt so hard. I had _________to become a teacher or a business administrator. I knew I needed a college degree, but I had _________ believing in myself.

4 . My photographs are the items I would definitely take or guard in case of an emergency. But what else? This was the question I asked myself as a ________ came toward us.

Unlike some friends and________, we decided to stay in our home. We didn’t have to choose what we would save by ________ it into the car, but we still had to decide what required protection by storing it in our walk-in closet. Surprisingly, few items made the cut - an obvious ________ that we had surrounded ourselves with beautiful yet unessential items. We needed ________ for the truly important things: ourselves.

Because when you hear the roar of the winds, or when something ________ hard against your windows, you don’t think of photos.You don’t worry about your big screen TV, or those paintings you’ve covered with towels to protect them, or that ________ car that you still haven’t finished paying for.

As ________ goes on outside, this is what you think: My children, are they OK? Are their impact-resistant(耐冲击的) windows working ________? Are their roofs keeping out the damage? My grandchildren, are they crying out in fear? Are they ________ as their own grandparents are? My relatives — yes, even those I try to avoid — have they ________ the worst of it? My friends, will they be forced to move somewhere else permanently?

Months and years after the hurricane, I often told people that there are two parts to ________ this kind of catastrophe: the horror of the hurricane itself and then the rebuilding that follows. The ________ together of a life, however, will take months, perhaps years.

But we will do it, ________ and as a community. Of that I have no doubt. In fact, I’ll make one more prediction. Piece by piece, item by item, we will once again collect the material possessions that decorate a home. I hate to admit this, but lessons learned ________ fear aren’t always long-lasting.

8 . My son “graduated” from elementary school this week. I put the word in quotations(引语)because as a rising 6th grader, he wasn’t receiving a _______ —and because the school used a _______ term to describe the milestone. On reflection, the school’s term felt even more _______ than the traditional name of the _______ of one stage of a person’s education: they called it Moving On.

At the Moving On Ceremony, each member of the 5th grade class _______ one sentence of reflection on what they were thankful for or would _______ about their primary school years.

9 . In modern cities, it is now time as much as space that separates urban functions, as people’s lives are lived not only to different timetables, but also at wildly different rates. The mass timetable of the industrial city, with 9-5 office hours and silent Sundays, has gone. In its ______ is flexi-time, part-time working, Sunday shopping and the 24-hour city.

European cities are ______ these changes perhaps faster than British cities. In at least half a dozen cities in Italy, ______, you will find the Uffici Tempi--the Offices of Time. What they do is try to reorganise time more flexibly in the city, in order to meet new needs. This is particularly relevant for Italian women, an increasing number of whom have to ______ two timetables: work and home. Usually located in the Mayor’s office, the Uffici Tempi bring together transport providers, shop-owners, employers, trade unions, the police and other services to see how their efforts might be better ______. The main aim in all this is to increase the efficiency and productivity of the city. This can mean delaying the starting tunes in schools, offices and factories to avoid rush hours, or having shops opening later in the day but closing later too. One further ______ is that there can be more police about in the evening, patrolling the streets when people most need them.

In a number of German cities, people have been ______ whether the timetable of the future city should be 6x6 or 4x9--working hours, that is. Apparently male workers favour a four-day week, while women workers, on the other hand, favour ______ shorter working days. This would give employees more time in the afternoon to be with children or to get the shopping.

The ______ for public services to adapt to our changing lifestyles has been quite difficult for some of the staff involved. ______, who likes working evenings or Sundays? Nevertheless, many city centres are now open for shopping seven days a week, and a number of them now promote themselves as ‘24-hour cities’, where those with money can drink, eat, dance and even shop the whole ______.

Time is flexible, but buildings aren’t. The ______ between the structure of the city and its uses, over time, is a serious architectural and planning problem. ______ has become the key skill. We are slowly ______ the terms of dormitory suburbs and industrial districts, in favour of mixed- use areas, out-of-town retailing and working from home. There is no doubt that planning theory is being ______ by the changing nature of time in the modern city.

10 . Being a social butterfly just might change your brain: In people with a large network of friends and excellent social skills, certain brain regions are bigger and _______ connected than in people with fewer friends, a new study finds.

The research suggests a _______ between social interactions and brain structure. “We’re interested in how your brain is able to allow you to _______ the right way in complex social environments,” Mary Ann Noonan said, a neuroscientist (神经学家) at Oxford University. Studies in monkeys have shown that brain areas involved in face processing and in predicting the _______ of others are larger in animals living in large social groups than in ones living in smaller groups.

To investigate these brain _______ in humans, Noonan and her colleagues found 18 participants for a structural brain-imaging study. They asked people how many _______ they had experienced in the past month, in order to determine the size of their social networks. As was the case in monkeys, some brain areas were _______ and better connected in people with larger social networks. “These different brain regions are all singing _______ songs,” Noonan said. “ _______ areas are all singing the same song, and when they’re connected better, they’re singing more harmoniously with each other.”

The researchers also tested whether the size of a person’s social network was connected with ________ in white-matter pathways, the nerve fibers (纤维) that connect different brain regions. ________ , they found that white-matter pathways were better connected in people with bigger social networks. “The nerves were more like a Los Angeles freeway than a ________ road,” Noonan said.

The researchers couldn’t say whether social interaction ________ these changes in brain structure and connectivity, or whether the brain determined how social someone was. In the case of the monkeys, the researchers asked and wrote down the size of the animals’ social network, so they ________ that social-group size was causing the brain differences. It can be inferred that a similar process takes place in human brains, but to prove the ________ , long-term studies are needed, Noonan told Live Science.
