怎么一出新款手机，你的旧手机就恰好被摔坏了？其实，这可能是升级效应所致。

我们来看一段相关的英文报道

If you've dropped, shattered or misplaced your phone more than usual in recent months, there could be a good reason.

Scientists claim that as soon as a new phone comes out, people tend to act recklessly with their existing phones - without even realising it.

Researchers believe this is because we are conditioned to avoid the guilt of upgrading to a more expensive model without proper justification. They've labelled this phenomenon theupgrade effect.

如果你近几个月比平时更容易掉手机，摔坏手机，或者把手机放错位置，那你可能真的有充足的理由。

科学家表示，一旦有新款手机面世，人们对现有的手机就更加“肆意妄为”，而自己根本意识不到。

研究人员认为，这是因为人们下意识地为自己给手机升级换代找个理由，以避免“罪恶感”。他们将这种现象称之为升级效应。



【讲解】

文中的upgrade effect就是“升级效应”的意思，其中upgrade用作动词，意为“升级；提高；改善”，如：Please click here to upgrade your Player.（请单击此处，升级您的播放器。）

第二段中的recklessly用作副词，表示“不顾后果地；卤莽地”，如：I've never seen a car being driven so recklessly.（我从没见过有人开车这么卤莽。）相关的单词还有：reckless（鲁莽的；不计后果的）、reck（介意；顾虑；与…有关系）。
