In South Korea, smartphone cases come with rings tied on the back of the mobile phones to prevent clumsy owners from dropping them. This makes people look like they literally are     1     to their phones. In many of Seoul’s most Instagrammable coffee shops, couples on dates spend     2     more time looking at their screens than at each other. The results go beyond the potentially damaging consequences this may hold for romance.

Walk around the streets of Seoul or any other South Korean city, and there is a real risk of bumping into people whose eyes are     3     to their smartphone screens. Insurers     4     that around 370 traffic accidents annually are cause by pedestrains using smartphones. That figure does not include those who bump into lamp posts and the like while watching the latest cat videos.

The government     5     tried to fight the “smombie” (a combination of “smartphone” and “zombie”) epidemic (传染病) by distributing hundreds of stickers around cities appealing to people to “be safe” and to look up. This seems to have had little effect, so the South Korean-capital has recently     6     the stickers with sturdier (结实的) plastic boards.

Instead of appealing to people’s good     7    , the authorities have therefore tried to save them from being run over. Early last year, they began to     8     with floor-level traffic lights in smombie hotspots in central Seoul. Since then, the trail has been     9     around and beyond the capital. For the moment, the government is     10     old-fashioned eye-level pedestrian lights as well. But in the future, the way to look at a South Korean crossroads may be down.
