How to Create a Mind Map

Most of us think visually but write textually. 【小题1】It also makes the information we list more difficult to process，remember，and share.

【小题2】It combines the brain's visual nature with our tendency to write down words. We end up with a diagram that combines logic and order in a less structured manner. This promotes clearer thinking and better comprehension. 【小题3】

So，how do you create a mind map？The most basic method is to just use a pen and paper，or a marker and whiteboard. It begins with a central topic or idea，then flows outward. 【小题4】 The next level of topics is represented by branches extending from it.

There aren't really any rules for creating mind maps. While most flow outwardly from the central topic，some users prefer to build mind maps in one direction. 【小题5】This can make groups of ideas easier to identify（识别）and remember. It also makes a mind map more enjoyable to create and use.

Mind maps are extremely effective for taking notes, planning a project, brainstorming an idea, presenting information to others, and many other uses. Take out your pen and have a try.

   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.
