显示去年窃贼（BURGLAR)光顾了两百多万户人家。人们实际上几乎无法将蓄意行窃的盗贼拒之门外，所能做的只是设法阻拦他片刻，从而使其暴露在巡警（POLICE PATROL）或附近溜达的人们面前。常识告诉我们光照是犯罪行为的障碍物。家门口必须安装一盏灯，并在晚间开着。不管你是否相信，有些人，尤其是最晚进家的孩子，晚上进屋后不把门锁上。空心门（DOOR OF HOLLOW CORE），即便锁上了，也易遭贼侵入。因此最好选择实心（SOLID CORE）门或铁门，因为窃贼很难将它们撬开。如果你有意购买报警装置，别忘了索要报警器的标志，并把它们张贴在窗户和门上。最后，提醒一句，外出旅游时，一定要请一位信得过的邻居，在你回来前帮你收好每日的报纸和邮件。这是因为放在门阶（DOORSTEP）上或邮箱里成堆的报纸邮件如同广告一样使大家都知道你家里没人。

The extraterrestrial has been a topic of interest to experts and laymen/nonprofessionals alike.Researchers of various nationalities and organizations are adopting different modes of investigation in search of extraterrestrials.Some make a close observation of stars with extremely high levels of rare,radioactive elements.They believe those elements have resulted from extraterrestrial technology that is still beyond human wits to understand.Some try to isolate radio noise from the "noise" of the universe.And some claim that they have caught sight of extraterrestrials and can even describe their appearance in detail.Researchers work up the complicated data they collect into a series of reports and books.Although no definite answer has yet been found,the explorers' hope shows no sign of fading out on account of their frustrations and they hold to the belief that their hard efforts will prove worthwhile.

After Dolly was born,cloning could no longer be dismissed as science fiction.The ability to create an identical twin of a lamb is but one step short of cloning humans,which many find terrifying and offensive.However the technology holds great potential for medical application.Scientists could cultivate a batch of cells and direct them to grow into whole organs or even limbs that will be genetically identical to those to the patient,thus eliminating the problem of rejection caused by immune reaction when they are transplanted into his body.Or they could take an organ from animals such as a pig that has been genetically altered so that will be tolerated by the recipient.Then the lives of thousands of patients who die every year before a replacement heart,liver or kidney becomes available would be saved.
