Living with a roommate can be a great experience as many roommates become lifelong friends. However ,roommates living together under the same roof for a long time unavoidably have conflicts（冲突） with each other. 【小题1】To prevent this from happening to you,each conflict should be handled in a productive,healthy way.

Once conflicts occur, you need to set up a time to discuss the conflict. 【小题2】 They may think about any problems they want to discuss. It also allows for a better discussion as both roommates will most likely enter the discussion fairly calm.

Before discussing the actual conflicts, set up some rules to guide the discussion. For example, each roommate is allowed to bring up one problem at a time and the other roommate has a chance to respond to it before another one is brought up. Making rules beforehand can prevent a screaming match from breaking out. 【小题3】

You can use your discussion to point out to your roommates their great advantages and specific things you like about them. While this won't solve the conflict, it can help your roommates be more understanding of your point of view and more willing to compromise（妥协）.

Once dissatisfaction has been said by both parties you should develop a roommate agreement that is written down. This agreement should discuss what the rules are as well as what results exist for breaking them. For example,roommates having a conflict about overnight guests may compromise to allow overnight guests only on weekends or guests on weekdays leaving by 11 p. m. 【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.

   Here are four principles (行为准则) I live by. Whenever I follow these guidelines, I am at my very best, feeling productive and happy.

Devote time.

No matter how talented we may be, it’s wrong to think we can do it all. 【小题1】 The value of our achievements is greatly decided by what we spend our time on. We need to realize that every day we should devote the time to what matters and have the courage to let the unimportant things go.

Focus your attention.

Very often it seems that we just can’t focus our attention, even though we know what we should be doing, right? Resistance (阻力) makes us get disturbed by distractions.【小题2】 Developing a plan for overcoming resistance is important for maximum productivity.

【小题3】

We need to make a balance between work and play, between creation and pleasure.【小题4】 Even if we feel energetic to work long hours, the most effective long-term way is to hold ourselves back when we feel crazy and follow a proper pace instead.

Keep moving on.

More important than setting big goals is to just keep going. I know this goes against most of the “ set great goals for yourself” advice, but it’s what works for me.【小题5】 And it always made me more worried than it helped. Now, what does work for me is to think about how to improve my life and take small steps to make it happen.

   After the age of 25， the number of friendships we maintain begins to fall. 【小题1】

Learn to identify opportunities.

“We let chances to make friends pass us by every day，” says Kate Leaver in her book The Friendship Cure.  【小题2】“Instead of forcing a little small talk with your kind neighbours，” she says， “ask them in for a cuppa and get to know them. ” 

 【小题3】

Joining a group， club or class is an effective way to meet people. “Teaming up for a shared activity，project or goal is an experience that can promote bonding and closer connections，” says therapist Miriam Kirmayer. Pursue a challenge or skill you are interested in， because then you will have a good time and feel more at ease in starting a conversation.

Allow yourself to be vulnerable（脆弱的）.

 【小题4】 What if your offers are rejected? Leaver and Kirmayer say that a degree of vulnerability is needed in trying to start friendships. Keeping to yourself isn’t going to help you. Sharing recommendations or letting others in on plans， says Kirmayer， is a simple way to share， which will help build closeness and trust.

Don't put too much pressure on it.

As we age， our friendships change. According to a 2016 study， we hit our peak number of friendships at the age of 25. 【小题5】 clinical psychologist Linda Blair advises not putting too much pressure on any new connections and not expecting too much from one person.
