Step 8  Language points

1. All of a sudden, WHAM! 突然，嘭！

all of a sudden突然

相当于suddenly, 在句中作状语，常放在句首，说明某一动作发生时的情况。

2. I went down hard on my right side. 我从右边重重地摔下去了。

go down摔下去，掉下去

【拓展】 go down还可表示“（风、浪）平息下来；（洪水）下落；（价格）下跌”。

3. I felt so terrible that I lay down again. 我感觉如此糟糕以至于又躺下了。

so…that…如此……以至于……  that引导结果状语从句。so为副词，后面接形容词或副词。

This story is so interesting that I want to read it again.

这个故事如此有趣以至我想再读一次。

【拓展】 so…that…可与“too+形容词/副词+to do sth.”“形容词/副词+enough+to do sth.”进行同义转换。

The boy is so young that he can’t go to school.

= The boy is too young to go to school.

= The boy is not old enough to go to school. 这个男孩太小了，不能去上学。

4. Then I saw blood on my shoe. 然后我看见鞋上有血。

blood名词，意为“血”。其动词形式为bleed，意为“流血，失血”。

Your nose is bleeding. 你的鼻子流血了。

5. As I lay there, I took off my helmet.躺在那里时，我摘下了头盔。

take off摘下；起飞  

put on穿上，戴上

Now we can take off the caps. 现在我们可以摘掉帽子了。

The plan takes off at 4 o’clock. You do have some time.

飞机四点起飞。你还有些时间。

【注意】take off是“动词+副词”型短语，人称代词作宾语时，应放在take和off中间。

The coat is dirty. Take it off and I will wash it for you.

这件外套脏了。把它脱下来，我来给你洗。

6. There was a sharp rock sticking out of it. 一块锋利的石头从我的头盔穿出来。

stick动词，意为“插入；穿入”。其过去式为stuck，过去分词为stuck。

常用短语有stick out of“从……伸出来”，stick…into…“将……刺入”。

你犯了那么多错误。你太粗心了。

8. The tyres are neither too full nor too flat. 轮胎既不太鼓也不太扁。

neither…nor…既不……也不……

连接两个并列成分。连接两个主语时，谓语动词遵循“就近原则”，即与nor后的主语在人称和数上保持一致。

She seemed neither surprised nor worried. 她似乎既不惊讶也不担心。

Neither my grandparents nor mum is at home today.
