A Cooking Accident
1b
James lived in the city with his friend Allen. It was their first time living away from their families, and they enjoyed learning how to do many things themselves.
One Saturday, James decided to make fried chicken. First, he poured oil into a pan. Then he turned on the stove and left the oil to heat while he prepared the chicken. Just then, he heard the front door open, followed by the sound of Allen singing.
“Guess what,” Allen called out happily. “We won!”
“No way!” James followed him into the living room. He wanted to hear all about the football game! Suddenly, Allen stopped talking and looked up.
“Hey, do you smell something burning ”
“Oh no!”
They both rushed back into the kitchen. The pan was on fire! Large flames were jumping into the air. In a panic, James turned off the stove at once. But he was so close to the pan that a flame jumped onto his shirt. James cried out and threw himself to the floor. He put out the fire by rolling on the ground, but the pan was still burning!
“Get water, quick!” he shouted.
Allen was about to do so when he stopped short. Thanks to the first aid and safety classes he took at school, he knew that water could make oil fires much worse! Instead, he ran to the living room to get the fire extinguisher. In seconds, the fire in the burning pan was put out.
“Are you OK ” Allen asked his friend.
“I think so,” James said. It was lucky that his shirt wasn’t too thin! His arm was red, but it didn’t hurt very much.
“Maybe we should eat out tonight,” James said as he ran cool water over his arm.
“Sure, we could do that. What do you want ”
“Anything but fried chicken,” he said sadly.

enjoy是动词，意为“享受；喜爱”，其后接动词时，要用其动词-ing形式。

how to do many things themselves是“疑问词+动词不定式”结构。疑问词可以是how、what、when、where等。

2. Then he turned on the stove and left the oil to heat while he prepared the chicken. 然后他打开炉子，让油加热，同时他准备鸡肉。
turn on意为“打开”，是一个“动词+介词”短语。
拓展： turn的相关短语还有：

turn down 调低 turn up 调高 turn off 关闭
拓展 when 可指一段时间，也可指时间点，while只指一段时间。
while 在此处作连词，意为“与……同时；当……的时候”，引导时间状语从句，从句常用进行时态。
While I was doing my homework, my father came back home fromwork. 当我正在做作业时，我父亲下班回家了。

这本书如此有趣，以至于我们每个人都想看。
归纳 与“so...that”相关的常考点：
①含“so...that”的复合句可以与“too...to...”和“not...enough to...”转换。

=The stone is too heavy for me to carry.
=The stone is not light enough for me to carry.

6. It was lucky that his shirt wasn’t too thin! 幸好他的衬衫不太薄。
句中的 It 是形式主语，它指代的是后面 that his shirt wasn’t too thin这件事。that his shirt wasn’t too thin 是一个由 that 引导的主语从句，它是整个句子的真正主语，说明“幸运”具体是什么事情。
