The conch (海螺) is       1     (wide) considered to be the national dish of the Bahamas. Queen conch is one of important food materials and can live for 30 years.

Conches can be very     2     (expense) in the U.S. and other places. But it is so common in the Bahamas     3     it can often be found in meals costing     4    (little) than two     5     (five) of the population in rural (农村的) parts of the Bahamas eats conches weekly. The country of about 400,000 is home     6     9,000 conch fishers-around two percent of the population. This number appears to be holding steady even as conches decrease (减少) in number. For many fishers here, fishing is both a family tradition     7     a path to middle class life. The meat of the conch     8     (be) worth millions of dollars per year, and it also helps increase tourism to     9     islands.

The conch is one example of the threat (威胁) overfishing presents to traditional foods around the world. Similar problems     10     (see) in Senegal now, where overfishing has taken away white grouper. The fish has long been the basis for the national dish of thieboudienne.

Over and over at the UN climate summit in Glasgow, world leaders have stressed the need     1     (limit) global warming to 1. 5 degrees Celsius. Experts have said crossing the 1. 5 ℃threshold(界限）risks     2     （release) far more severe climate change effects on people, wildlife and ecosystems. Preventing it     3     (require) almost halving global CO₂ emissions(排放) by 2030 from 2010 levels and cutting them to net-zero by 2050.

Already, the world has heated to around 1. 1℃ above pre-industrial levels. Each of the last four decades was     4     (hot) than any decade since 1850. “We never had such a global warming in only a few decades,” said climate     5     (science) Daniela Jacob at the Climate Service Center Germany.

More warming to 1. 5 ℃ and beyond will     6     (worse) such impacts. For example, heatwaves would become both more frequent and more severe. A warmer atmosphere can also hold more moisture(水分), resulting in more extreme rainfall     7     raises flood risks. It also increases evaporation, leading to more intense droughts.

“At 1. 5 ℃, there’s     8     good chance that we can keep most of the Greenland and west Antarctic ice sheet     9     collapsing,” said climate expert Michael Mann at Pennsylvania State University. That would help limit sea level rise to a few     10     (foot) by the end of the century.

Bemidji high school senior Jaxon Anderson is     1    awkward teenager who wants to be everyone’s hero. When he puts on the mask, however, Anderson becomes the amazing Spider-Man.

“I     2     (struggle) for senior photos for months and I believe this would make me stand out among my classmates and help me be myself,” Anderson said. “I love superheroes. I guess I’m just really cool     3     that way.”

Spiderman’s pictures are just the     4     (late) in a trend that some people are calling “extreme senior portraits”. “Everyone wants to do something outside of the box,” said Megan Engeseth of Megan Engeseth Photography, a studio     5     is known for its creative senior portraits. “It’s a     6     (total) different thing even from five years ago.”

High school seniors no longer want to graduate with a regular yearbook picture.     7     most still take a traditional headshot (头像) for Mom and Dad, they want the rest of their photos to reflect their true     8     (personal). And they want the photo shoot experience     9    (make) them feel like a famous person – or superhero – for a day.

The goal for many seniors — especially the girls — is to end up with an     10     (impress) set of pictures to be shared and liked on social media. With millions of pictures on the Internet, the bar (门槛) is high.

Gather a couple of friends and take a leisurely walk through the streets—this is    1    many youngsters enjoy doing when they visit a new city. To them, citywalk means wandering around the city on foot. Participants can follow a distinctive urban route,    2     (explore) the city at their own pace. Compared with famous    3    (spot) and big crowds, they prefer to gain a more inclusive experience of the places they visit.

Dressing smartly is, of course, important for your confidence and sense of self-empowerment. But your style can do more than just send     1    (message), to your mind or to others. New research shows that the clothes you wear can actually have a significant effect     2     how you think. Professional dress, according to the study, increases abstract thinking and even gives people     3     broader viewpoint. “The degree of formality of clothing not only could affect     4     people assess a person and how people assess themselves, but could influence decision-making in important ways through its influence on the processing style,” the researchers say. They also find that formal clothing is     5     (associate) with enhanced (增强的) social distance and can increase     6    (psychology) distance between people. When you are more socially distant, you tend     7    (think) in a more distant and abstract way. For example, in distant social situations, titles rather than names     8    (use) to call an unfamiliar person. Even after controlling socioeconomic status, people     9     wear more formal clothing show a stronger preference     10     abstract processing.
