Question

in the night at night
网上说in the night是指某个时候,
The temperature fell sharply in the night.那天夜间温度急剧下降.
难道夜间温度是某时候就瞬间下来了吗?说不通
高考完型和语法会不会考这玩意儿

Answer 1

in the night:
在夜间
at night 在夜间, 在傍晚. 一般可指整个夜间或午夜以前.如：
My mother asks me not to have the light on at night.我妈妈叫我不要夜里让灯一直亮着.
Father often comes home from work at night. 爸爸经常午夜下班回家.
in the night 在夜间,在夜里（某个时候）.
I hear a cry for help in the night.夜里我听到有人喊救命.
当这两个词组用作“在夜间”时,可以换用.如：
Thieves often come out in the night (at night).
He likes to work in the night（at night）.
如果表示“在傍晚”时,只能用at night或 in the evening,而不能用 in the night.
The school is over at seven in the evening.这个学校晚上七点放学.
英语这东西要悟的,而且一般不会让你辨别这俩的.就是出题的话也是这样出的：
I woke up ___ night .
A in the B at the C in D all
