Five Simple Ways to Increase Your Intelligence
Your brain needs exercise just like a muscle. If you use it often and in the right ways, you will become a more skilled thinker and increase your ability to focus. Here are 5 simple ways anyone can squeeze a bit more productivity out of the old gray matter.
小题1:_______
This is a hard sell. People love vegetating in front of the television, myself included more often than I’d like. The problem is watching television doesn’t use your mental capacity or allow it to recharge. It’s like having the energy sapped out of a muscle without the health benefits of exercise.
When you feel like relaxing, try reading a book instead. If you’re too tired, listen to some music. When you’re with your friends or family, leave the tube off and have a conversation. All of these things use your mind more than television and allow you to relax.
小题2:_______
I used to think that I’d learn more by not exercising and using the time to read a book instead. But I realized that time spent exercising always leads to greater learning because it improves productivity during the time afterwards. Using your body clears your head and creates a wave of energy. Afterwards, you feel invigorated and can concentrate more easily.
小题3:______
Many people like to read popular suspense fiction, but generally these books aren’t mentally stimulating. If you want to improve your thinking and writing ability you should read books that make you focus. Reading a classic novel can change your view of the world and will make you think in more precise, elegant English. Don’t be afraid to look up a word if you don’t know it, and don’t be afraid of dense passages. Take your time, re-read when necessary, and you’ll soon grow accustomed to the author’s style.
小题4:_______
Nothing makes it harder to concentrate than sleep deprivation (剥夺睡眠). You’ll be most energetic if you go to bed early and don’t sleep more than 8 hours. If you stay up late and compensate(弥补)by sleeping late, you’ll wake up lethargic(无精打采) and have trouble focusing. In my experience the early morning hours are the most tranquil and productive. Waking up early gives you more productive hours and maximizes (使……最大化)your mental acuity(敏锐) all day.
If you have the opportunity, take 10-20 minute naps when you are hit with a wave of drowsiness. Anything longer will make you lethargic, but a short nap will refresh you.
I hope you aren’t disappointed that none of the techniques I’ve proposed are revolutionary. But simple, unexciting answers are often the most valid. The challenge is having the will to adhere to them. If you succeed in following these 5 tips, you’ll be rewarded with increased mental acuity and retention of knowledge.

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 become 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 come 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. Become familiar with people who live in the building, so you can keep track of anyone that is a stranger.
