有的人一个晚上可以啃完一本大部头，有的人却一看到书上的字就止不住的犯困，后者被称为“轻量级读者”，英文表达是lightweight reader。
Lightweight reader refers to someone who gets sleepy or passes out shortly after starting to read.
“轻量级读者”指的是那些一开始看书就犯困或者看没多久就睡着的人。
Contrary to “heavyweight”, which means very powerful, “lightweight” means having little ability, and lightweight reader is a reader who is not good at reading, in fact, far from good at it. You can also call him a poor reader.
和“重量级”（意思是十分强大）相反，“轻量级”的意思是能力极低。“轻量级读者”则是不擅长阅读的人，事实上，离擅长阅读差得很远。你也可以把“轻量级读者”叫作poor reader。
Example:
"I’m so screwed for this test, I didn't study at all."
"Why not? We had all week!"
"I’m a lightweight reader man, I never made it past section one."
“我这回考试铁定完蛋，完全没学习。”
“为啥呀？咱们不是有一整周的时间吗？”
“我是个轻量级的读者，总是翻不过章。”
