What are some of the steps a person can take to prevent his house from being broken into while he is away? One step is to make sure that the house seems a lived-in one. Living room curtains should be pulled down only half-way. Bedrooms that usually have the curtains pulled down at night should be left down. Another is to make sure that all outside locks are the dead-bolt type (双保险) . Still another is to leave several 100W lights burning and make sure that one is in the kitchen. Lights that turned on and off by themselves are the best. Then, too, it is a good idea to leave the radio turned on and set to a talking station. Any type of speaking makes a thief think twice before trying to enter. Finally, while away on holiday, make sure that nothing collects in front or in the house. Particularly, make certain that the newspaper is stopped and that a trusted neighbour has been asked to pick up the mail. Thieves are especially quick to notice piled-up newspapers and overpiled mail boxes.

和其他两个人的区别在于前两道题。第一题问第一句话的作用：“你知道怎样能......”这样的话是吸引注意还是概括全文？比较有争议，你自己斟酌哪个好吧。
不过我可以确定第二道题是我对了。live-in中文意思是“有人在'肯定选b阿，怎能选c（每人使用）呢？
