() 1. My classmates are interested in a book named Black Beauty.

1. C

【分析】首先识别题干中的固定短语“be interested in”，该短语中“in”是介词，介词后接动词时需用动名词形式（动词的-ing形式），据此判断选项。
【解析】“be interested in”是固定搭配，意为“对……感兴趣”，其中“in”为介词，介词后接动词需用动名词形式。选项A是动词原形，B是动词不定式，D是动词第三人称单数形式，均不符合语法要求；选项C是read的动名词形式reading，符合规则，因此选C。
【答案】C
【知识点】固定搭配、动名词用法
【点评】本题考查英语基础语法中的固定短语搭配，属于高频基础考点，只要掌握“be interested in后接动名词”的规则即可轻松作答，难度较低。

二、阅读理解
You have big eyes and a small nose. But your friend has small eyes and a big nose. What makes you and your friend look different?
The answer is genes (基因). Scientists found that 15 genes decide (决定) some of our facial features (面部特征). Some of these genes can be passed down (被传给后代) from parents to children. That’s why we often hear people say, “You look like your mum” or “You look like your dad.”
But what facial features do you get from your mum? And what parts come from your dad?
Eyes
If both of your parents have double eyelids (双眼皮), you can have double eyelids or single eyelids (单眼皮).
If both of your parents have single eyelids, you usually (通常) have single eyelids.
Chin (下巴)
If one of your parents has a big chin, usually you have a big chin.
Nose
If one of your parents has a big nose, you may have the same nose size.
Skin (皮肤) colour
If one parent has a light skin colour, and the other parent has a dark skin colour, most of the time, you have a skin colour in between.
No two faces are the same. Even twins don’t look the same. Their looks are just very similar (相似的). They can have some small differences.
