今天我们接着来看第79课的“每课一句”。

一、课文原文

Lesson 79 By air

I used to travel by air a great deal when I was a boy. My parents used to live in South America and I used to fly there from Europe in the holidays. A flight attendant would take charge of me and I never had an unpleasant experience. I am used to travelling by air and only on one occasion have I ever felt frightened. After taking off, we were flying low over the city and slowly gaining height, when the plane suddenly turned round and flew back to the airport. While we were waiting to land, a flight attendant told us to keep calm and to get off the plane quietly as soon as it had touched down. Everybody on board was worried and we were curious to find out what had happened. Later we learnt that there was a very important person on board. The police had been told that a bomb had been planted on the plane. After we had landed, the plane was searched thoroughly. Fortunately, nothing was found and five hours later we were able to take off again.

二、每课一句

I am used to travelling by air and only on one occasion

have I ever felt frightened.

注意这句话中的“only on one occasion have I ev er felt frightened”，这是一句倒装句，其原本的正常语序应该是：

I have ever felt frightened only on one

occasion.

这句话之所以采用倒装，是因为only on one occasion提到了句首。需要注意的是：

在英语中，当“only+状语”置于句首时，

会引起部分倒装。

only后面的状语可能是副词、介词短语或从句：

1、only+副词

Only then did I realize that she was our

English teacher.

只到那个时候我这才意识到，她是我们的

英语老师。

2、only+介词短语

Only in this way can we pass the test.

只有这样我们才能通过考试。

3、only+从句

Only when he came did we have the

money to buy the house.

只有当他来了之后，我们才有钱买下这座

房子。

三、更多拓展

After taking off, we were flying low over the city and slowly gaining height, when the plane suddenly turned

round and flew back to the airport.

注意本句话中的when并不是表示“当...时候”，而是表示“在那时；当时”，相当于at that time。

此时，when后接的从句所表达的内容往往是偶发的，具有一定的突发性。

再比如：

Yesterday afternoon, I was walking in

the park, when I suddenly ran into an old

friend of mine.

昨天下午我在公园里散步，

这时我突然碰到了我的一个老朋

友。
