我国水资源分布不均，且水土资源匹配不合理，下列地区中缺水最严重的是（    ）

    ①想真正了解一个人，要长期观察他所做的事。如果他慷慨无私，不图回报，还给这世界留下了许多，那就可以肯定地说，这是一个难得的好人。

    ②那是在1913年，我走进法国普罗旺斯高原，在游人稀少的阿尔卑斯山地，做了一次旅行。这里海拔一千二三百米，一眼望去，到处是荒地。光秃秃的山上，稀稀拉拉地长着一些野生的熏衣草。在无边无际的荒野中，我走了三天，终于来到一个废弃的村庄前。我在倒塌的房屋旁边支起帐篷。从前一天晚上起，就没有水喝了。现在，我必须去找点儿水。我猜想，这里虽然成了废墟），但是，像马蜂窝一样、一间挨一间的房子周围，总会有一口水井，或是一眼泉水吧！我确实找到了一个泉眼，可惜已经干涸了。这里有五六栋没了屋顶的房子，任由风吹雨打。旁边还有一个教堂，钟楼也已经坍塌了。这一切，让人能想象出当时人们在这里生活的情景。如今，却一点儿生气也没有了。那是六月晴朗的一天，太阳快要把人烤焦了。在毫无遮拦的高地上，风吹得人东倒西歪。狂风呼啸着穿过破房子的缝隙，像一只饥饿的野兽发出吼叫。我打消了在这里过夜的念头。

    Nowadays, more and more people like to shop on the Internet.  How can you protect yourself from different types of Internet tricks?  Following these tips can make you online shopping safer：
    (1) Never click on an unsolicited(主动提供的) e-mail.  If you are interested in the things well-known company that sells the same thing, don't click on any links in the e-mail itself.
