我原以为上次考试我会不及格，但是没有想到我竟然及格了。

（2）above all: 首先，重要的是。

　　例如：

Above all, I love taking a walk every evening.

首先，我喜欢每天晚上散步。

（3）at all:常用于否定句和疑问句，表示加强语气。常翻译成："根本、丝毫"等。

　　例如：

I'm not at all sorry I came, I'm glad! 我来了一点也不遗憾，我很高兴。

There was nothing at all to eat. 根本就没有什么东西吃。

Are you at all worried about the forecast? 你对这项预报不担一点心吗？

（4）in all: 意思是"总计"。

　　例如：

There were twelve of us in all for dinner. 我们一共12人吃饭。

　　三、重点句型

1．I'd rather not tell you.

　 注意：somebody would rather do something表示"某人宁愿做某事"；它的否定句表示"某人还是别..."。

　　例如：

　 I would rather go there by bus. (我宁愿坐公共汽车去那里。)

　 I would rather not sit there doing nothing. (我不愿坐在那里什么都不做。)

2．on't touch anything, unless your teacher tells you to.

unless引导的从句有时可以和if引导的否定条件句互换，此句可以改成：..., if your teacher doesn't tell you to.　另外要注意句末的to后省略了touch something。

　　再如：

I won't go with you unless you tell me who will be with us.

　　如果你不告诉我谁将和我们一起，我就不会和你一起去。

3．here's no doubt that 100 years ago animal testing was cruel but today animals in experiments are very well taken of.

　　此句中There's no doubt that...为固定句型，意思是"毫无疑问"。

再如：
