答
你好,很高兴为你解答!
这里考察的是名词作定语的知识.
作定语的名词往往是说明其中名词的材料、用途、时间、地点、内容、类别等.
⒈材料
a diamond necklace
a bamboo pole
paper money
a stone bridge
⒉用途
a meeting room
the telephone poles
the railway staion
trade union
water pipe
welcome speech
eye drops
⒊时间
a day bed
the dinner party
the Apring and Autum Period
evening suit
midday lunch
⒋地点
London hotels
Beijing University
body temperature
the spaceship floor
the kitchen window
⒌内容
a story book
piano lessons
the sports meet
oxygen supply
the air pressure
the grammar rules
⒍类别
children education
enemy soldiers
a bus driver
school不属于这些可作定语的名词范畴,而birthday是作用途,因此可作定语.
~~~不懂可追问,满意请采纳~~~
