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”
It was a beautiful afternoon. 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. It 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 leg were bleeding. There was an ugly cut on my knee. 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!

Further discussing
Grammar focus
Read the sentences and pay attention to the parts in yellow.
I was riding my bicycle by the river.
My hand and leg were bleeding.
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
过去进行时 (Past continuous tense)
e.g. I was riding my bicycle by the river around noon.
My hand and leg were bleeding.
过去进行时态一般表示在过去某一时刻或某一段时间内正在进行的动作。动作的时间可以用介词短语、副词或从句来表示，也可由上下语境暗示。
1. 过去进行时的构成
过去进行时的构成是“was/were + v-ing”。过去进行时常与表示过去的时间状语连用（当上下文有时间暗示时，也可以省去时间状语）。
2．过去进行时的用法
（1）表示在过去某个时间点正在进行的动作。
e.g. What were you doing at 10:00 last night
The children were playing in the garden when a giant appeared.
（2）表示过去某一时段正在进行的动作。
e.g. During that time, I was playing tennis a lot.
They didn't go to the beach today because it was raining.
肯定句：主语+was/were+动词现在分词(+其他).
e.g. I was sleeping at 10 p.m. last night.
否定句：主语+was/were+not+动词现在分词(+其他).
e.g. I was not sleeping at 10 p.m. last night.
一般疑问句：Was/Were+主语+动词现在分词(+其他)
肯定回答：Yes, 主语+was/were.
否定回答：No, 主语+wasn't/weren't(was+not/were+not).
e.g. Were you sleeping at 10 p.m. last night
Yes, I was./No, I wasn't.
特殊疑问句：特殊疑问词+was/were+主语+动词现在分词(+其他)
e.g. What were you doing at 10 p.m. last night
3．过去进行时的结构
注意：有些动词通常不用于进行时，主要有：
1. 表示心理状态、情感的动词，如love、hate、like、 know等。
2. 部分连系动词，如seem、appear等。
3. 感官动词，如see、hear、feel、smell、sound、taste等。
4. 短暂性动词，如decide、stop等。
