老师留的作业,实在做不出来啊~
There is a common English word that is nine letters long. Each time you remove a letter from it, it still remains an English word---from nine letters right down to a single letter. What is the original word, and what are the words that it becomes after removing one letter at a time?

Cleansers
Cleanser
Cleanse
Cleans

Can
An
A

Crewmates

STARTLING
starting remove L
staring remove second T
string remove A
sting remove R
sing remove T

我不太理解这句"话from nine letters right down to a single letter".为什么就要从l开始减起呢?
