知识梳理
1.All of a sudden,WHAM!
◆all of a sudden意为“突然”,相当于suddenly,常在句中作状语,说明某一动作发生时的情况。
◆wham在本句中为感叹词,意为“砰,嘭”,它还可用作名词,表示“重击声,重击”;用作动词表示“重击,砰砰地打”。
2.I went down hard on my right side.
◆go down在本句中意为“倒下”。
【拓展】go down还可意为“下去,蹲下,下降”。
◆on在本句中意为“凭借,靠”,side意为“(身体)侧边,肋”,on my right side在这里指“我以右侧身体着地”。
3.“There’s something wrong with me,”I thought.
“There's something wrong with…”意为“……有问题”,相当于“Something is wrong with…”,其否定式为“There is nothing wrong with…”或“There isn't anything wrong with…”。
4.I felt so terrible that I lay down again.
◆so…that…意为“如此……以至于……”。so为副词,后面可接形容词或副词,that为连词,后接结果状语从句。与so…that…类似的结构为:such…that…。二者意思相同,不同的是such后面接名词。so…that…引导结果状语从句,可以与too…to…或“not+形容词+enough to do sth.”作同义句转换。
【拓展】(1)so后面也可以接名词,但应该有many,much,few,little等表示量的形容词对名词加以修饰,这时句式结构为:
①so many/few+可数名词复数+that从句
②so much/little+不可数名词+that从句
(2)so…that句式在修饰可数名词单数时还可以用在下面的句式中:
so+形容词+a/an+可数名词单数+that从句。
◆lie down意为“躺下”。
5.My hand and knee were bleeding.
bleed为动词,意为“流血,失血”,是blood的动词形式,其过去式、过去分词为bled。
6.As I lay there,I took off my helmet.
take off在本句中意为“脱下”,反义词组为put on。
【拓展】take off还表示“(飞机等)起飞”之意。
7.There was a sharp rock sticking out of it.
stick out of意为“从……伸出来”。stick为动词,意为“插入,穿入”,过去式、过去分词为stuck。
8.Thank goodness I wore my helmet!
◆thank goodness意为“谢天谢地”,也可说成thank God。
◆I wore my helmet是省略了引导词that的原因状语从句。
9.When my mother got to the hospital,she gave me a big hug.
when为从属连词,引导时间状语从句,表示主从句的动作同时发生,或从句的动作发生在主句动作之前。另外,对时间提问也可以用when。
10.She knew I was careless and did not always wear my helmet.
careless为形容词,意为“粗心的”,其反义词为careful“细心的”,其副词为carelessly“粗心地”。
骑自行车应该注意的事项
Have you ever experienced an accident Let's look at some pictures.
There are so many accidents in our life.We should always be careful.
My name is Jackie. I like cycling.
It was a beautiful fall day. I was out riding my bicycle. 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.
My Helmet Saved My Life!
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 stranger 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. “I'm so glad you were wearing your helmet，”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!
