   Having a roommate can be one of the best experiences in college or, easily, one of the worst. It all depends on whether you have a good relationship with your roommate or not. Follow the advice to avoid the common mistakes that turn good roommate relationships bad.

◇ 【小题1】

Communication is key. If something happens, sit down with your roommate and have a face-to-face conversation. I’ve seen roommate relationships fall apart because something happens and instead of talking to each other, the two start complaining about their roommates behind their backs. 【小题2】

◇ Don’t expect to be best friends.

Some roommates become the best friends, and some don’t. Don’t put pressure on yourself or your roommate, especially when you first meet. 【小题3】 And if your roommate doesn’t end up being your best friend, don’t worry.

◇ Ask before you take.

This applies (适用) to food, clothes and anything else. If you want to keep a relationship going, show your roommate that you have respect for what is his or hers by asking first. 【小题4】

◇ Clean up after yourself.

This should be done without saying. Don’t be lazy. Or, at least, don’t bury your roommate in your clothes and garbage. Most people I’ve come across in college are dirty and untidy. 【小题5】 But putting your stuff in order will help you avoid conflict.

How to make friends at a new school

Starting with a new school can be difficult. Everything seems to be different, and you don’t even know where to go for your own classes. 【小题1】 However, if you use these skills, you can quickly turn some of those strangers into friends.

Be yourself.

【小题2】 If some people don’t accept you, they’re not the kind of friends you need. People often stay together because they have similar interests. For example, someone who does a lot of sport may make friends with those who also run or swim a lot.

【小题3】

Remember to be nice to the people you meet at your new school. If you think that you will say something that may make them feel sad, do not anything and just nod your head if they talk to you. Also, remember to be as helpful as possible!

Believe in yourself.

A smile goes a long way. When you walk in the halls, don’t keep your eyes on the floor. Raise your head and make eye contact （目光接触） with other people. 【小题4】 Introduce yourself. Tell them your name and where you’re from.

Remember people’s names.

You like it when people use your name, and so do other people. People may become angry if you just begin by saying "Hey" each time. Besides, ask them in a kind way if they have a nickname （绰号） . 【小题5】

   A strong memory depends on the health and vitality（生命力）of your brain. They say that you can't teach an old dog new tricks，but when it comes to the brain，scientists have discovered that this old saying simply isn't true. 【小题1】

Give your brain a workout. Memory, like muscular strength, requires you to“use it or lose it”. The more you work out your brain, the better you' ll be able to process and remember information. 【小题2】

Don't skip the physical exercise. While mental exercise is important to brain health, that doesn't mean you never need to break a sweat. Physical exercise helps your brain stay sharp. It increases oxygen to your brain and reduces the risk of disorders that lead to memory loss.

Get enough sleep. There is a big difference between the amount of sleep you can get now and the amount you need to function at your best. 【小题3】

Keep stress in check. Stress is one of the brain's worst enemies. Over time, stress destroys brain cells. Studies have also linked stress to memory loss.

Have a laugh. 【小题4】 That holds true for the brain and the memory, as well as the body. Unlike emotional responses, which are limited to specific areas of the brain, laughter involves multiple regions across the whole brain.

【小题5】 Just as the body needs fuel, so does the brain. You probably already know that a diet based on fruits, vegetables, whole grains,“healthy”fats and lean protein will provide lots of health benefits, but such a diet can also improve memory. For brain health, though, it's not just what you eat — it's also what you don't eat.
