1. (2022高三上·沈阳月考) 阅读理解

Have you ever been seized with a kind of warm and unclear feeling when you start an old-fashioned game? Or maybe when you think back to celebrating the holidays as a kid, something magical just seems to be missing now. That's nostalgia.

In the early 20th century, nostalgia was considered a mental condition similar to depression. Anyone separated from their native place for a long time was easy to suffer nostalgia. But over the next few decades, the meaning of nostalgia has expanded from indicating homesickness to a general longing for the past. And rather than an awful disease, it turns out to be seen as a bittersweet experience.

From several former studies, researchers of the University of Southampton supposed nostalgia might protect people from being in bad mood, even when they think about upsetting thing — like death. To test it out, they conducted an experiment, where 75 people wrote about their own deaths, and then did a word completion task, in which they were asked to complete different words based on a six-letter word starting with C-O-F-F. The people who thought about dying but didn't get nostalgic answered with many death- related words, such as "coffin"，while the nostalgic people gave more answers unrelated to death like "coffee", almost as if they'd, never thought about death in the first place.

The researchers think that could mean nostalgia, despite being a complex emotional state that can include feelings of loss and sadness, doesn't generally put people in a negative mood. Instead, by allowing individuals to remember personally meaningful and rewarding experiences, nostalgia can boost psychological well- being. These studies are pretty limited, though, and there's still a lot we don't know about nostalgia.

Still, these studies support that nostalgia has a purpose; If people are feeling down, it might cheer them up. But there are also some less helpful side effects. For example, advertisers have discovered how powerful nostalgia is as a marketing technique, for nostalgia in ads can make people part with cash more easily. So, it is not all sugar cookies.
