Unit 2
Stay Healthy
1a Discuss the questions.
1. Look at the picture in 1b. Can you describe what is happening
In the picture, it seems that there is a big fire in the pot on the stove. The oil in the pot is burning fiercely, and two people are reacting to this dangerous situation.
2. Do you know what to do if oil catches fire
If oil catches fire, we shouldn’t pour water on it, because water will make the fire much worse. Instead, we should turn off the gas or electric stove first to cut off the fuel source, and then cover the pot with a lid to cut off the oxygen, so that the fire can be extinguished.
1b Read the story and find out how the fire started.
A Cooking Accident
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.
It is/was one’s first time doing sth.，意为“某人第一次做某事”。
The fire started when James left the overheating oil unattended on the stove while going to the living room to talk to Allen.
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!”
pour... into... 把……倒进……
形容词形式为happy。
“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!”
名词短语，意为“不可能；没门”。
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.
意为“突然停住”，为不及物动词短语。还可意为“（做事）中途放弃”，stop short of (doing) sth.“差一点儿没做某事”
长难句分析：这是一个主从复合句。Thanks to...作原因状语，在he knew that water could make oil fires much worse中，主语是he,谓语是knew,宾语是that引导的宾语从句。
“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.
指在餐厅、饭店等非家中场
所用餐。take out打包带走。
“Sure, we could do that. What do you want ”
“Anything but fried chicken,” he said sadly.
是由“sad（adj.悲伤的）+-ly（副词后缀）”构成的。
