老师：因为它们一样可爱，所以我们用英语这么说：

as......as的用法
当我们表示双方某方面（如年龄、身高等）程度相同或不同时，常用as…as或not as…as 结构，表示“和…一样”或“和…不一样”。
如：Mary is as careful as Linda. 玛丽和琳达一样仔细。
He does not run as fast as Tom. 他跑步没有汤姆快。
注意：1. “as+形容词或副词词原级+as.”意为“和……一样”,表示同级的比较,
“not as +形容词或副词词原级+as” ,意为“和……不一样”,表示同级的比较。
2. 在否定结构中，“A is not as …as B”意思是“A不如B…..”
This book is not as interesting as that one. 这本书不如那本有趣。
= This book is less interesting than that one.
= That book is more interesting than this one.
3. 在同级比较的否定句中，我们也可以使用not so …as结构。如：
This desk is not as heavy as that one. 这张桌子不如那张重。
=This desk is not so heavy as that one.
= This desk is lighter than that one.
4. 当我们对事物进行比较时，要注意被比较的对方必须是同类事物。如：
Her ruler is as long as me. (错误)
Her ruler is as long as me. (正确)
