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)。

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.

Here are my tips:

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.

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 with the same thing.

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.

Make friends slowly.

I couldn't get discouraged (泄气的) when it took a while to make friends.It really takes some time to make new friends. In a word, ________________________.

 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 it!
