Lesson 79 文本  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. An airhostess 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, an air-hostess 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. 文本解析 一）词汇学习Word study 1. plant vt.（1）种植；在……内种植：Trees were planted along the river.河边栽了树。They planted grass seed on the desolate hills.他们在那些荒凉的山丘上撒播草籽。Joe plants his garden with many flowers and vegetables.乔在他的花园里种植了许多花卉和蔬菜。 （2）放置，安置；布置：A bomb was planted on the plane.飞机上安放了一枚炸弹。On that day many policemen were planted along the main street.那天（城里的）主要街道上部署了许多警察。 2. 与take有关的短语动词take可以与许多小品词连用而产生不同的含义，与同一个小品词连用时也可以有多种含义，这里仅选其中的一小部分。（1）take off最常用的含义为“脱下（衣服、鞋子等）”：Why don't you take off your coat/hat/glasses?你为什么不把你的大衣脱掉／帽子摘掉／眼镜摘下？它还可以表示“（飞机）起飞”或“（鸟）飞起”：After taking off, we first flew low over the city.起飞之后，我们先在城市上空低低地飞行。The plane will take off in half an hour.飞机将于半小时后起飞。在口语中，take off可以表示“（嘲弄地）模仿”：As a boy, Jim used to take off his elders.吉姆小时候经常模仿长者。 （2）take after表示“（长相、性格等）像（父母等）”：Jane isn't easy to get along with.
