阅读下面的短文，并根据短文后的要求答题(请注意问题后的字数要求)。
[1] Many students find it hard to make friends when they are in high school. Keeping my suggestions in mind may give you a hand. They certainly helped me, and by the end of my three years of high school I had formed my group of friends, with whom I still keep in touch now.
[2] Here are my tips：
[3] Say hello anytime I see an acquaintance(相识的人)．
Because I was always smiling and greeting the people I knew, people naturally thought I was friendly(though I am not naturally sociable). And high school students want to be friends with sociable people.
[4] Take the first step.
All the girls there already knew each other—they didn't need another friend. But I did, so I had to make the effort. I had to be the first one to invite somebody to go to a movie with me，or come to my house. Once I did that they started to respond(回应)with the same thing.
[5] Use classes to get to know people.
I met most of my first friends because I sat next to them in class. Class (before, after, or even during class time)is a great opportunity to begin a conversation. For example, ask for help about homework.
[6] Make friends slowly.
I couldn't get discouraged when it took a while to make friends. It really takes some time to make new friends. In a word, ________.
[7] Above all, remember that it can and will get better. You may have to work a little to make your high school experience a great one，but it' s really worth(值得) it!
