谁有这种铅笔英文怎么说
时间：
这种铅笔英语可以称为 "mechanical pencil"，也可以称为 "automatic pencil"。
"Mechanical pencil" 是指使用机械机构来驱动铅芯的铅笔，这种铅笔的设计使得用户可以不停地转动铅芯以保证铅笔尖部始终保持圆整。
"Automatic pencil" 也是指使用机械机构来驱动铅芯的铅笔，但是这种铅笔可以使用按钮或其他方式来推出铅芯，而不需要用户手动转动铅芯。
下面是一些使用 "mechanical pencil" 和 "automatic pencil" 的例句：
I always carry a mechanical pencil with me because I never know when I might need to take notes or make a sketch.
I prefer using an automatic pencil for writing because it's easier to control the pne width.
Do you have a mechanical pencil I can borrow? I left mine at home.
I've been using the same automatic pencil for years and it still works perfectly.
