题干

根据短文内容,填写下列表格,每格只填一词。

    I'm Jane from America. I can not sleep well and I always wake up several times during the night. I know for a fact that there are many other people who have trouble going to sleep, too. So, I've collected some advice I've received over the past few months that have not only helped me get to sleeper faster, but helped me get better night sleeps.

    Have regular sleep habits

    Go to bed at the same time every night. Try not to break this habit on weekends when you may be made to stay up late. Wake up at the same time every day. If you're getting enough sleep, you should wake up naturally without an alarm.

    Turn off your computer

    Don't play on the computer for half an hour before you decide to sleep. Studies show that it is bad for the quality of your sleep. Read a book or listen to some light music to prepare your body for sleeping.

    Have a nice bedroom

    A clean environment helps people to be happy and relaxed. Make sure that you have turned off all light that might come into your room, and that the temperature is comfortable.

    Exercise often

    Exercising will help you to fall asleep more easily, so walk out for 45 minutes every day and you will sleep better at night. But don't do it just before you go to bed-you won't be able to sleep!

    Eat properly

    Eat only a little for supper. A full stomach may make it much harder for you to sleep.

                                                                                                                             身在“辐”中要知“辐”
        ①手机有辐射、电脑有辐射、冰箱有辐射、微波炉有辐射、电吹风有辐射、电视机有辐射、太阳光也有辐射……现代人早已身在“辐”中。可是,我身边很多人对于“辐射”两字,可以说是谈“辐”色变。如果是这样,那说明你身在“辐”中不知“辐”,因为辐射远没有你想象中的那么可怕。
        ②“辐射”是科学上常用的一个名词,指的是物体以电磁波或粒子的形式向周围发射能量的过程,也称为“放射”。如果辐射会说话,它一定会非常得意地说:“我无处不在,你无处可逃!”□如此,你□不用怕了。因为,怕也没用!
        ③依据能量高低及电离物质的能力大小,可以笼统地把辐射分为电离辐射和非电离辐射。
        ④所谓“电离”,一般而言,是指电子被高能辐射从电子壳层中击出,使原子带正电。拥有足够高能量的辐射可以把原子电离,人们因而称之为“电离辐射”。核辐射就是一种高强度的电离辐射。人体组织中的每一个细胞大约由数万亿个原子组成,一旦受到核辐射,就会无差别地破坏人体细胞中原子的化学键。当破坏的程度非常之大,人体自身无法修复时,就会出现致癌、致死等情况。更可怕的是,为了修复被破坏的原子化学键,人类的基因可能会发生突变。一旦生殖细胞基因发生了突变,就有可能遗传给后代。据说,1986年苏联切尔诺贝利核电站爆炸后,当地有些老鼠受到核辐射,基因发生突变,如今有的老鼠已经和猪仔差不多大了。
        ⑤非电离辐射,是指含有的能量很低,不足以让原子电离,它是由电场和磁场交互作用产生的电磁波向外释放形成的,所以也被称为电磁辐射。例如紫外线、红外线、激光、微波都属于非电离辐射。在我们生活中最容易接触到的就是太阳光和一般家用电器发出来的非电离辐射。
     ⑥我们天天接触的都是非电离辐射,事实上我们一点也不用怕它。
        ⑦首先,家用电器的功率很小,相对的辐射“剂量”也很有限,一般不足以对人体造成伤害。大家都知道在家用电器中,微波炉算是“辐射剂量”超大的了,但微波是无法穿透金属的。一般微波炉都是全金属外壳,所以,一个合格的微波炉是不可能让微波出来游逛的。
        ⑧其次,“魔高一尺,道高一丈”,人类早就发明了很多防范辐射的方法。比如,给微波发生器加上金属罩;放射工作人员穿上专门的防护衣服;核电站的核反应堆深埋地下,并加上层层防爆防护罩;医院的放射治疗室用特殊材料制造,以免辐射外泄……
        ⑨再次,对于自然界中的辐射,如太阳光,因为人类从古到今一直面对它,已经产生了一定的抵抗力和适应性,人体皮肤完全可以吸收小剂量的辐射,并把它转化成热量。
        ⑩随着人类对辐射的认识逐渐增加和人们健康意识的增强,防辐射的办法越来越多。所以,辐射想干点坏事,还真不容易找到机会呢。当然,辐射也并不是总干坏事的,它也能为人类造福。我们熟知的一些医疗手段,比如癌症放疗、核磁共振检查、X光检查、CT扫描,都是利用了辐射。
        ⑪如此看来,我们身在“辐”中要知“辐”,这样我们才能很好地利用辐射为我们的生活服务,也就不会谈“辐”色变了。
