阅读《凶手WiFi》一文，回答下列各题。
凶手WiFi
       ①近日，一群来自丹麦的女学生用水芹种子进行实验，得出了惊人的发现：WiFi信号可能会损害健康。
       ②由于学校没有监测大脑活动的设备，女孩们选择了水芹种子作为研究对象。她们将12个装有水芹种子的盘子平分为两组，其中一组放在没有任何WiFi信号的房间里；另一组则放在两台运行中的无线路由器旁边。十二天的时间里，覆盖有WiFi的房间内，大多数种子变成了褐色，然后死亡。而另一间房里的种子则正常生长。
       ③虽然有人认为，种子之所以在覆盖有WiFi的房间中死掉，可能是路由器散热所致。但此项实验结果还是加剧了人们对WiFi辐射的恐惧感，有些家长和教师们要求校园内禁止安置无线路由器。
       ④与此同时，实验也得到了荷兰研究者的力挺。三年前，荷兰的科学家选用白蜡树作为研究对象，他们将这些树木分别放在距六个辐射源0.5米处的位置，辐射源的频段介于2412赫兹到2472赫兹，功率为100毫瓦﹣﹣和无线路由器相似。靠近辐射源种植的树木，树叶上出现了“具有类似铅光泽”的物质，导致叶片的上下表皮死亡，最终掉落。
       ⑤但是，美国的一些研究者对这些研究成果表示怀疑，他们认为，由于WiFi采用的是低强度的无线电波传输信号，其威力只是微波的十万分之一。在一间覆盖WiFi的屋子里待上一年，受到的辐射量仅相当于用手机进行20分钟通话。
       ⑥不过需要提醒的是，如果WiFi使用不正确，也极可能对人体造成伤害。那么，作为普通用户，在使用无线路由器时应该注意什么呢？
       ⑦首先，人体接受的辐射量跟频率有关，频率越高，伤害越大。因此，家中没有必要使用功率过大的无线路由器。
       ⑧其次，辐射危害大小还跟距离有关，距离越远，危害越小。如果家中有孕妇、小孩、老人或免疫力低下者，最好让无线路由器与他们的活动范围保持较远的距离。
       ⑨第三，最好不要将WiFi设备放置在卧室内，尤其是放在床边。如果不使用WiFi，最好将无线路由器关闭，以降低不必要的风险。
       ⑩还有，别在腿上使用笔记本电脑，最好将电脑放在桌子或托架上。

阅读理解

    In 1943, when I was 4, my parents moved from Coeur d'Alene, Idaho, to Fairbanks, Alaska, where adventure was never very far away.

    We arrived in the summer, just in time to enjoy the midnight sun. All that sunlight was fantastic for Mum's vegetable garden. Working in the garden at midnight tended to throw her timing off, so she didn't care much about my bedtime.

    Dad was a Railway Express agent and Mum was his clerk. That left me in a mess. I usually managed to find some trouble to get into. Once I had a little fire going in the dirt basement of a hotel. I had tried to light a barrel(桶) of paint but couldn't really get a good fire going. The smoke got pretty bad, though, and when I made my exit, a crowd and the police were there to greet me. The policemen took my matches and drove me home.

    Mum and Dad were occupied in the garden and Dad told the police to keep me, and they did! I had a tour of the prison before Mum rescued me. I hadn't turned 5 yet.

    As I entered kindergarten, the serious cold began to set in. Would it surprise you to know that I soon left part of my tongue on a metal handrail at school?

    As for Leonhard Seppala, famous as a dog sledder(驾雪橇者), I think I knew him well because I was taken for a ride with his white dog team one Sunday. At the time I didn't realize what a superstar he was, but I do remember the ride well. I was wrapped(包裹) heavily and well sheltered from the freezing and blowing weather.

    In 1950, we moved back to Coeur d'Alene, but we got one more Alaskan adventure when Leonhard invited us eight years later by paying a visit to Idaho to attend a gathering of former neighbors of Alaska.
