AEIS词汇积累："2B铅笔"的 B 是哪个单词？

在备考中存在这样几种误区，相当一部分家长认为AEIS考试的语法题所占分值不大，且学生在学校里的语法学得挺扎实的，对孩子的语法非常自信。关于AEIS考试，就拿写作为例，写作一般都要求句式的多样性，对学生句法的掌握和熟练运用有较高的要求。

Soft leads are graded using the letter ‘B’ to designate how ‘black’ the mark they make is. Numbers are then used to indicate the degree of softness - the higher the number the softer the lead and the blacker the mark. For example, a 2B lead is softer than a B lead and will produce a blacker mark. A 4B lead is softer than a 2B etc.

软铅芯用字母B来表示它们黑的程度。然后，数字被用来表示柔软程度——数字越高，铅越软，所以画出来越黑。例如，2B铅比B铅软，会产生更黑的痕迹。4B比2B等要软。

Hard leads are graded in the same way, but use an ‘H’ to show how ‘hard’ they are. A 2H is harder than an H and a 6H is really really hard.

硬铅芯以同样的方式评级，但用H来表示它们有多硬。2H比H硬，6H非常非常硬。

HB (hard black) leads are considered to be the happy medium on the graphite scale. There are no specific industry standards that set down how black HB leads should be, so an HB pencil made by one manufacturer will not necessarily leave the same mark as an HB pencil from a different manufacturer.

硬黑铅被认为是石墨刻度上的理想中值。并没有具体的行业标准来规定HB铅笔芯应该有多黑，所以一个制造商生产的HB铅笔并不一定会和另一个制造商生产的HB铅笔留下相同的痕迹。

pen lid笔帽

sharpen[ˈʃɑːrpən] v. 使变尖;使锋利

sharpen a pencil削铅笔

pencil sharpener转笔刀;卷笔刀

我们削铅笔的是想要铅笔的笔芯变得更尖，方便书写，而不是只削掉铅笔的皮，所以削铅笔要说 sharpen a pencil，削铅笔要用的卷笔刀就是 pencil sharpener.

例：

His mother told him to sharpen pencils before the exam.

妈妈叮嘱过他，在考试前削好铅笔。
