【答案】D
【解析】
试题分析:考查非谓语动词和固定搭配。句意:公益广告一般是免费播放,它们旨在向人们传递有关健康、安全或任何其它影响公共福利的问题等方面的知识。逗号之间的部分是插入语,是一个过去分词短语,PSAs和run之间是动宾关系,即公益广告被播放,应该用过去分词,排除B、C;be meant/intended for sth/to do sth旨在......,相当于be aimed to do sth,故选D。

【题目】There are a number of advantages when it comes to living alone. However, it also comes with a few safety concerns. You still never know who will be around the corner. Don’t be another victim; be sure to follow our tips.
1. All doors should be kept locked.
Always keep your doors locked when you are in your apartment or dorm. Make sure the doors are closed behind you when you come into the building and never leave your room unlocked, even when you are in it. There’s always a chance that someone might sneak in while you are unaware. Always try to remember to close doors behind you to ensure your safety.
2. Don’t lose your keys.
Even if you do everything you can to keep the doors locked, criminals might still be able to e into your house with a key. Always know where your keys are to prevent this. Never put them down in a public place or give them to friends. Also, before you bring your car into the repair shop, take off the house keys.
3. When it comes to safety, standing up for yourself is important.
If you aren’t getting all the security features you want, don’t be afraid to ask. If your lighting situation is less than ideal, discuss this with your supervisor or landlord. Talk to the campus security organization if you think a security phone near your dorm is a good idea. Request that the building employ someone to monitor those entering and leaving the building. You should feel safe where you reside (居住于), so stand up for your rights.
4. Be careful.
You still might find yourself in a potentially dangerous situation. Check your peephole (窥视孔) before letting anyone in. Whenever you witness something around your building that makes you uncomfortable or suspicious just dial 911. It is a good idea to always walk with a friend instead of alone. Be familiar with people who live in the building, so you can keep track of anyone that is a stranger.
