【小题1】The AmE spelling of the Chinese word “颜色” in this dictionary is ________.

阅读下列材料，从所给的六个选项(A、B、C、D、E、F)中，选出符合各小题要求的最佳选项。选项中有一项是多余选项。
A. School or work
B. Make small talks
C. Be fun to be around
D. Be reliable
E. Get out and meet people
F. Join people of common interests
In the world, many people want to make friends just as you do. Follow these steps to meet new people and build strong, lasting friendships with at least some of them. The following paragraphs are some steps.
【小题1】      . You don’t necessarily have to have a lot of common interests with people in order to make friends with them—in fact, some of the most rewarding friendships are between two people who don’t have much in common at all, but if you have something in common with people, it can make it a lot easier to talk to them. Whatever your age and whatever your interests, there is a club or an organization for you.
【小题2】      . Friends can talk about just anything, but you don’t want to get too personal when you first meet someone. Just make good, small talks at first.
【小题3】      . You don’t have to be a superstar to be fun. You do need to be positive and friendly, however, so that people feel good when they’re around you. From the very first conversation you have with someone, you should use body language. Smile frequently, laugh often, and make eye contact. In your words, be confident.
【小题4】      .The steps above are great for making acquaintances (认识的人), but how do acquaintances become lifelong friends? One important feature of a good friend is reliability. When you say you’ll do something, do it. Be someone that people know that they can depend on.
【小题5】      . If you want to make friends, you first need to meet people. No matter where you live, this should be very easy.
