Question

----------语法问题-----------
he wrote a________report.
A.two-thousand-words
B.two-thousand-word
C.two-thousands-word
D.two-thousands-words
答案说是D,但是我记得thousand复数形式好像就是原型,答案到底应该是什么呢,

Answer 1

答案应为B,
two-thousand-word为合成形容词,合成形容词中出现的名词应使用单数形式.
又如：a five-year plan; a eighty-metre-long bridge
至于你所说的thousand,为数词,只有thousands of（好几千的）短语中,即表示不确定数目的时候才有复数形式.
