How to Be a Great Best Friend

    Everyone wants to be a great best friend but doesn't know how or where to start that perfect friendship. The following will help you.

    Be your own best friend first. {#blank#}1{#/blank#} If you can't respect yourself, then you can't respect others. Understand what values are important to you and stick to them. Seek out others who honor those values because you'll only end up hurting yourself and possibly others if those people don't have the same values as you.

    Trust each Other. {#blank#}2{#/blank#} All you have to do really is make sure you can both trust each other. Don't try to trick or use your friend to your advantage; you need to make them know they can trust you.

Whenever your best friend says something, listen carefully and say something. {#blank#}3{#/blank#} If they ask for advice, listen carefully arid give them the best advice you can.

    Let your friend have other friends, too. If your best friend picks another friend over you, try to be friend over you, try to be friend too. {#blank#}5{#/blank#} Everyone is always looking for new friends.

Four Tips for High School Graduates

    Over three­million high school students are graduating this spring in the United States. Many of them will head to university in the fall. The transition (过渡) from high school to college is a major one, and successful adjustment to college has lifelong influences.

    Maybe you are about to make this transition yourself or have children who are about to leave the nest. {#blank#}1{#/blank#} If you know someone who is making this transition or know parents guiding their soon­to­be adult kids through this time, please take a moment to share this collection of research­based tips with them.

    Be open to making new friends as soon as you set foot on campus. Even during orientation (迎新会)! {#blank#}2{#/blank#} Your success in college depends, in part, on surrounding yourself with others who can support you and help you have fun.

    {#blank#}3{#/blank#} Successful adjustment is about reaching out for help when you need it. This means trying to find the answers on your own first, but then contacting those who can help you when you can't. That is what they are there for!

    Lean on your family. Family support can give you comfort when classes get hard or you are stressed about finals. {#blank#}4{#/blank#} Strong support from family is linked to lower loneliness and depression during the first year of college and higher academic adjustment including motivation and concentration.

    Be confident. Feeling anxiety about communicating with fellows, professors, and speaking up in class is associated with lower adaptation during the transition to college. One of the best ways to increase your communication confidence is to practice! {#blank#}5{#/blank#}

A. This list is for you.

B. The more you speak up in class, the easier it becomes.

C. Don't be afraid to talk to your professors or teaching assistants.

D. Joining clubs is also linked to feelings of belonging at college.

E. Your professors and teaching assistants want to see you succeed in their classes.

F. Almost everyone is in the same boat as you are, hoping to make friends quickly.

G. Family members can give you advice and help you solve problems if you need help.

    Do you have a place you've always wanted to visit? If the answer is yes, have you ever considered taking a trip alone there just for a few days?

    {#blank#}1{#/blank#}Although seeing the world on their own has always been a dream in their hearts since childhood, most people have repeatedly been told that the outside world is dangerous. The thought of going on a trip alone excites and terrifies them at the same time. Few end up stepping out of their comfort zone and going on meaningful adventures.

    It is normal to have some trouble traveling alone. {#blank#}2{#/blank#} For example, being alone on the road, you might have to ask strangers to take your photo wherever you go. If you join a tour halfway, you may be asked why you don't have friends or family around. {#blank#}3{#/blank#}

    First, traveling alone gives you a good opportunity to do everything you wish to do without worrying about others' needs and wants. If you want, you can read on a bench beside a river for the whole afternoon without being disturbed (打扰). You are free to walk around on different streets. {#blank#}4{#/blank#} You can also remove that dull daily routine (常规) that always makes you feel tired.

If you make good use of it, traveling alone can also be a wonderful journey of self-discovery, as you'll finally have time to think about your life.

    {#blank#}5{#/blank#} All you need to do is pack your bags, take your passport, gather up your courage and go somewhere. Go out and enjoy being alone, explore the unknown, make some friends, read a book, and get to know more about yourself and the world.

A. Traveling by yourself is also quite easy.

B. You can go to shopping malls and explore the city.

C. For many people, traveling alone can be frightening.

D. There are also some unpleasant moments one might run into.

E. It is important to take some time off and think about the methods.

F. But anyhow, I still suggest that you travel alone at least once in your life.

G. Traveling alone helps us figure out what we really want to fight for in this big world.

What do a picturesque sunrise, a nice cup of coffee, and holiday celebrations have in common? {#blank#}1{#/blank#}Being open about your feelings can be rewarding. Here are some reasons for sharing your feelings with others.

Expressing your feelings connects you with others. When it comes to relationships with your family and significant others knowing how to express your feelings is the key to creating intimacy (亲密关系). {#blank#}2{#/blank#}However, it is that sincere revelation(透露) that enables you to bond with your loved ones.

{#blank#}3{#/blank#}In a study, after participants expressed their emotions, brain images showed a decrease in the brain activity in the amygdala, the part of the brain associated with feelings, indicating a calming effect on the brain. The researchers concluded that talking through emotions decreases the strength of these emotions.

Sharing your feelings boosts health. According to The New York Times, holding everything inside and not expressing your emotions can be harmful. {#blank#}4{#/blank#}But choosing to appropriately share them benefits you mentally and physically. By doing so, you can normalize your speaking about emotions and emotional needs. This can help not just you, but also others.

Speaking about your emotions enables you to get help.When you put what's in your mind into words, you are making that experience or emotion real, instead of ignoring it. That's a way of recognizing yourself. Moreover, talking about your feelings allows your loved ones to help you. They are naturally concerned about your well-being. {#blank#}5{#/blank#}

All in all, accept your feelings, even negative ones and learn to manage them. Practice sharing your feelings on a regular basis, and you will benefit a lot.

A. Opening up keeps emotional intensity down.

B. Sharing your emotions improves brain function.

C. Telling others about the depths of your feelings can be scary.

D. If so, you'd better avoid judging yourself and other people.

E. These are all wonderful experiences that you can share with loved ones.

F. By letting them know what you're experiencing, you can get their support.

G. That may cause increased stress levels and risk of developing related diseases.
