Read and answer
Read the questions and give your answers.
A Do you wear a helmet when you ride a bicycle Why
B How do you understand the sentence “You can never be too careful.”
Yes, I do. Because wearing a helmet can protect my head from being injured while riding a bicycle.
It means we should always be as careful as possible in life. Accidents can happen unexpectedly, and being careful can help us avoid danger.
It was a beautiful noon. I was riding my bicycle by the river, thinking about yesterday’s baseball game. I guess I rode over a hole in the road. All of a sudden, WHAM! I went down hard on my right side. That really hurt!
My head hit the ground. I lay there for a few minutes. I tried to get up, but I couldn’t! “There’s something wrong with me,” I thought. I felt so terrible that I lay down again. Then I saw blood on my shoe. My hand and knee were bleeding. I was in a lot of pain.
As I lay there, I took off my helmet. There was a sharp rock sticking out of it. It was pretty scary to look at. Thank goodness I wore my helmet! I shouted for help. A driver stopped his truck and came to help me. He put my bike in the back of his truck and drove me to the hospital.
When my mother got to the hospital, she gave me a big hug and kiss. “You were wearing your helmet this time. How lucky you were!” she said. She knew I was careless and did not always wear my helmet.
But I’ll never be careless again... My bicycle helmet saved my life!

We use the past continuous tense to talk about actions that were in progress at a certain time or over a period in the past. The structure: was/were + v-ing
Grammar focus
过去进行时 (Past continuous tense)
过去进行时表示“过去某个特定的时间点或时间段内正在进行的动作”。
一、过去进行时的构成是“was/were + v. -ing”，具体句型结构如下：
句式 结构 例句
肯定句 主语+ was/were + v. -ing + 其他. He was reading a storybook at 9 last night.
昨晚 9 点，他正在读一本故事书。
否定句 主语+ was/were + not + v. -ing +其他. She wasn’t watching TV at 8 last night. She was studying.
昨晚8 点，她没在看电视。她在学习。
句式 结构 例句
一般 疑问句 Was/Were + 主语+ v. -ing + 其他 肯定回答：Yes, 主语+ was/were. 否定回答：No, 主语+ wasn’t/weren’t. —Were they playing basketball on the playground just now
刚才他们正在操场上打篮球吗？
—Yes, they were./No, they weren’t.
是的，他们在打。/ 不，他们没在打。
特殊 疑问句 特殊疑问词+was/were + 主语+v. -ing + 其他 What was he doing at 8 o’clock last night 昨晚8 点他正在做什么？
二、过去进行时的用法
1. 表示过去某一时刻正在进行或发生的动作，时间状语一般是表示过去的某一时间点。如at 8 last night, just then, at this/that time yesterday 等。
e.g. I was washing the dishes at 7 o’clock last night.
昨晚七点我正在洗碗。
2. 表示过去某段时间内持续进行的动作。
e.g. They were watching a movie from 6:00 to 8:00 yesterday evening.
昨天晚上6 点到8 点，他们一直在看电影。
While I was walking, it rained suddenly.
我正在走路时，突然下雨了。
3. 表示两个过去的动作同时进行，这时可用while 连接。
e.g. George was reading while his wife was listening to the radio.
乔治在读书，而他的妻子在听广播。
4. 表达褒贬等感彩：过去进行时可以和always、constantly、forever 等连用，表示说话人的主观感情，如赞扬、不满、厌烦等等。
e.g. He was forever complaining about something.
他老是怨这怨那。
特别提醒: 过去进行时中when 和while 的区别
when 强调“某个短暂动作(一般过去时) 发生时，另一个动作(过去进行时) 正在进行”。 e.g. I was doing my homework when my dad came back. 我爸爸回来时，我正在做作业。
while ① 强调“两个延续性动作同时进行”(主从句均用过去进行时) 。 ② 强调“在某个延续性动作(过去进行时) 期间，发生了一个短暂动作(一般过去时) ”。 e.g. My mom was cooking in the kitchen while my dad was reading newspapers. 我妈妈在厨房做饭时，我爸爸正在看报纸。
e.g. While we were playing soccer, it started to rain. 我们踢足球的时候，天开始下雨了。
