根据搜索结果，以下是关于如何用英文介绍自己和朋友的八句话建议，分点整理如下：

一、自我介绍

基本信息

"My name is [Your Name]. I am [age] years old and I come from [place]."（例如：My name is Tom. I am 12 years old and I come from Beijing.）

性格特点

"I am a [adjective] person. I like [hobbies]. For example, I enjoy reading and playing football."（例如：I am outgoing. I like sports.）

二、朋友介绍

外貌特征

"My friend is [adjective] with [hair/eyes/face]. For instance, he has short black hair and bright eyes."（例如：My friend is tall and handsome.）

性格与爱好

"He/She is [adjective] and loves [hobbies]. He is good at [skill]. For example, she is very humorous and enjoys playing the piano."（例如：He is outgoing and has the same hobbies as me.）

关系说明

"We are [relationship] since [time]. We often [activity]. For example, we go cycling together on weekends."（例如：We are good friends since childhood.）

三、注意事项

结构清晰：

先介绍姓名、年龄，再描述性格、外貌，最后说明关系，逻辑性强。

使用连接词：如"for example"、"for instance"等，使描述更生动。

避免重复：同一特征（如年龄）尽量只提及一次。

以上内容可根据实际场景调整，例如学生作文可侧重学习表现，朋友介绍可突出共同兴趣。
