阅读下面短文，根据其内容，完成表格中所缺的信息。 Some people prefer to make friends with people who are very much like them while others prefer friends who are very different. There are advantages to both types of friendship. If a man chooses a friend similar to himself, there is no problem that they will share many common interests. They may have similar goals in life. This means that they will be able to help each other in achieving their goals. Two people who are very similar will feel comfortable with each other and may understand each other' s feelings better. Their friendship may be deeper and last longer. There are also many advantages of making friends with someone of opposite interests and even character. In this type of friendship, the two people complement (补充) each other. If one is weak in some ways, the other is strong. While two people with similar goals may find themselves in competition, hut those who want different things can always support each other. Those who have different interests can introduce each other to new experience and so enrich (丰富) their knowledge. A friend who is unlike me may be challenging, but a similar friend is familiar and safe.
