Dr. Li found a strange glowing rock near her village. It shone brightly at night, and no one had seen anything like it before.
She took the rock to her laboratory. Her students helped her study it carefully. They took measurements and wrote notes every day.
One day, the rock stopped glowing. Dr. Li and her students were surprised. They did many tests but could not find the reason.
Then, they discovered the rock glowed only when it was cold. It was a special mineral that reacted to temperature changes.
The discovery made Dr. Li happy. She shared the new knowledge with scientists around the world. The glowing rock became famous.
难句解析
- 1
They took measurements and wrote notes every day.
“take measurements” 是固定搭配，意思是“进行测量”；不是“拿走测量工具”。整句意思是：他们每天都进行测量并做记录。
- 2
It was a special mineral that reacted to temperature changes.
“that reacted to temperature changes” 是定语从句，修饰前面的“a special mineral”，意思是“会对温度变化产生反应的”。整句：这是一种会对温度变化有反应的特殊矿物。
- 3
The discovery made Dr. Li happy.
“make sb. + 形容词” 结构，意思是“让某人变得……”。整句：这个发现让李博士很高兴。
本篇语法
一般过去时 (Past simple)
一般过去时表示过去某个时间发生并已经结束的事：I visited Beijing last year. 规则动词加 -ed：walk → walked；很多常用动词是不规则的：go → went, see → saw, have → had。否定和疑问用 did + 动词原形：I didn't see him. Did you call her?
verb-ed / irregular form · did / didn't + base verb
故事中的例句
- Dr. Li found a strange glowing rock near her village.
- She took the rock to her laboratory.
- One day, the rock stopped glowing.
- They did many tests but could not find the reason.
常见错误
说过去的事时动词不变（中文用“了”“昨天”表示时间）。
Yesterday I go to the park.
Yesterday I went to the park.
