阅读课文《我的叔叔于勒》选段,完成小题。

    我父亲A脸色早已煞白,两眼呆直,哑着嗓子说:“啊!啊!原来如此……如此……我早就看出来了!……谢谢您,船长。”

    他回到我母亲身旁,是那么神色张皇。母亲赶紧对他说:“你先坐下吧!别叫他们看出来。”

    他坐在长凳上,结结巴巴地说:“是他,真是他!”然后他就问:“咱们怎么办呢?”母亲马上回答道:“应该把孩子们领开。若瑟夫既然已经知道,就让他去把他们找回来。最要留心的是别叫咱们女婿起疑心。”父亲神色很狼狈,低声嘟囔着:“出大乱子了!”

    母亲突然暴怒起来,说:“我就知道这个贼是不会有出息的,早晚会回来重新拖累我们的。现在把钱交给若瑟夫,叫他去把牡蛎钱付清。已经够倒霉的了,要是被那个讨饭的认出来,这船上可就热闹了。咱们到那头去,注意别叫那人挨近我们!”她说完就站起来,给了我一个五法郎的银币,就走开了。

    我问那个卖牡蛎的人:“应该付您多少钱,先生?”他回答道:“两法郎五十生丁。”

    我把五法郎的银币给了他,他找了钱。

    我看了看他的手,那是一只满是皱纹的水手的手。我又看了看他的脸,那是一张又老又穷苦的脸,满脸愁容,狼狈不堪。我心里默念道:“B这是我的叔叔,父亲的弟弟,我的亲叔叔。”

    我给了他十个铜子的小费。他赶紧谢我:“上帝保佑您,我的年轻的先生!”

    等我把两法郎交给父亲,母亲诧异起来,就问:“吃了三个法郎?这是不可能的。”我说:“我给了他十个铜子的小费。”

    我母亲吓了一跳,直望着我说:“你简直是疯了!拿十个铜子给这个人,给这个流氓!”她没再往下说,因为父亲指着女婿对她使了个眼色。

    后来大家都不再说话。

    我们面前,C天边远处仿佛有一片紫色的阴影从海里钻出来。那就是哲尔赛岛了。我们回来的时候改乘圣玛洛船,以免再遇见他。

    It's the holiday season, the time when we connect with family and friends. Social media sites like Twitter and Facebook are full of festive pictures, featuring parents' catching and sharing those special family moments, their child's wish list, and maybe even a cute video of their child dancing to “Jingle Bell Rock” while wearing a diaper (尿片) and Santa hat. Swelling with pride, parents can't wait to get approval with a “thumbs up” or better yet a personalized message on their treasured post.

    Adults should be able to post what they want online. However, when exposing family moments online, are they sharing too much information? Do parents have the right to share those cute now, but embarrassing later moments about kids? Have children willingly given their agreement to sharing their cute but funny video online?

    A recent study found that 75% of parents turn to social media for parenting-related information and social support. There is even a term used to describe the overuse of sharing too much information about kids on social media: “sharenting”. Research also finds that “sharenting” isn't going anywhere anytime soon. What's troublesome is that a typical parent has about 150 Facebook friends and only a third of them are actual friends. So that brings up good questions – Who are we really sharing our information with and why? Who knows when and where that photo could resurface in the future?

    While there's no reliable information on how young children feel about things posted online, we do have information about how teens feel. According to a report by the Family Online Safety Institute, 76% of teens are concerned about their privacy. Many teens constantly search for new apps that allow anonymity. When names are required, they use screen names that don't reveal real information. If our teens are doing a better job of protecting themselves online, shouldn't parents take the lead and do the same? Plus, with more and more college admission representatives and potential employers surfing the internet for potential candidates, we'd hate for one of our posts to change an important decision. Think about it … online reputations are now becoming inseparable with real life ones.

    Of course, we can secure our privacy settings, only allowing our friends to view pictures, posts and videos, but that doesn't stop others from uploading our pictures. Adults need to be cautious of sharing information online, especially information about children.

    So, this holiday season, enjoy family time and share those special memories with family and friends. Before clicking the app to upload photos or videos, stop and think twice.
