    “Years ago when I was at the Grand Canyon, I remembered someone coming up to the canyon's edge, taking a shot with a camera and then walking away, like 'got it – done', barely even glancing at the magnificent scene in front of him,” Linda Henkel, a scientist at Fairfield University, US told Live Science.

    Henkel was surprised by how obsessed (痴迷的) people are with taking pictures these days - before dinner, during friends' birthday parties, on museum tours and so on.

    They keep taking pictures because they think that it helps record the moment, but as Henkel's latest study has just found out, this obsession may prevent their brains remembering what actually happened, reported The Guardian.

    In her study, Henkel led a group of college students around a museum and asked them to simply observe 15 objects and photograph 15 others. The next day the students' memory of the tour was tested, and the results showed that they were less accurate in recognizing the objects and they remembered fewer details about them if they photographed them.

    ''When people rely on technology to remember them — counting on the camera to record the event and thus not needing to attend to it fully themselves, it can have a negative impact on how well they remember their experiences,” Henkel explained.

    But there is also an exception: if students zoomed in to photograph part of an object, their memory actually improved, and those who focused the lens (镜头) on a specific area could even recall parts that weren't in the frame.

    So basically, this study is saying that constantly taking pictures can harm your memory. But shouldn't reviewing pictures we have taken help wake up our memories? This is true, but only if we spend enough time doing it.

    “In order to remember, we have to access and interact with the photos, rather than just collect them,” Henkel told The Telegraph. However, previous research has shown that most people never take the time to look over their digital pictures simply because there are too many of them and they aren't usually very organized on their computers.

送老师一捧叫“爱”的插花

    鲜花是美的代名词，是情的寄托，也是生命的象征。

    教师节要到了，让我们走进花卉市场，把最美丽的鲜花献给我们敬爱的老师，祝老师“节日快乐”！

    在人们的印象中，向日葵也叫太阳花，灿烂的花朵代表光辉和高尚；粉色康乃馨表达敬意与温馨；巴西木叶与春芋叶衬托出蓬勃的生机。那就买下向日葵、康乃馨、巴西木叶和春芋叶吧，再买一个方形的陶制花盆，插出名为“高尚”的盆花，连同那份美丽的心情和由衷的敬意，送给值得自己敬佩的老师。

    用一捧康乃馨做主花，陪衬着满天星和一片龟背竹，包上锡纸，比喻老师为人师表，事业有成。龟背竹既象征老师的宽阔胸怀，也象征自己生机盎然的进取意志，是拥抱成功的意义所在。用彩带精心地将花扎起来，起个名字叫“你心我心”，送给敬爱的老师，花语脉脉，表达相知的欣慰。

    虎头兰是高贵和富有的象征，用其做主花讴歌老师的品德高尚和知识渊博，最贴切不过了，鸢（yuān）尾配天冬草，更显得雅致和清纯，其中的情趣就尽在不言中了。精心扎出的这一捧鲜花叫做“恩师”吧，这是教师节最好的礼物。或者买下盛开的百合，它象征着恩师正如日中天，业绩辉煌。而且百合花的花香清淡宜人，默默散放，就像老师那种默默奉献的精神，买一只草编篮插起来，取名叫作“桃李满天下”，隆重地送到学校去，让老师们个个看了笑逐颜开。
