热身练习

一、口语训练

1、用正确的语音、语调朗读下列短文。

The sea looks very beautiful when the sun is shining on it. It can be very terrible when there is a strong wind.

The sea is very big. It covers three quarters of the earth. The sea is also very deep in some places. There is one place----the sea is about 11 kilometres deep there. The highest mountain in the world is about 9 kilometres high. If that mountain was put into the sea at that place, there would still be 2 kilometres of water above it.

In most part of the sea, there are lots of plants. Some live near the top of the sea, others live deep down. There are also a lot of small living things. Lots of fish live by eating them.

The sea can be very cold. When people go down, the sea becomes colder and colder. Only some men can go down into deep sea. But in 1970, five women scientists live in the deep sea for fourteen days.

2、根据实际情况回答问题。

3、根据提示说话。

假如你是李华，你向全班同学介绍上周星期六与好朋友刘军一起去参观了广州动物园，你们看到了很多动物，玩得很高兴。请用至少六句话来描述。
