Task 4

According to a recent survey, two-thirds of the world’s polar bears will be extinct by the mid-century. We heard “save the whales” in the 1990s, we are hearing “save the polar bear” now, we will hear soon “save the human beings”. For the next 10 minutes or so I’m going to look at some of the serious effects of global warming. Basically I’ve divided my presentation into 3 parts. In the first part I’ll talk about the melting glaciers and the way that these are c ontributing to rising sea levels. Then in the second part I’ll look at climate change and give you some examples of how this is having a serious impact on wild animals’ behavior and habitat. And in the final part I’ll focus on the retreating snowlines and consider how these are causing the death of certain species of trees.

3 Using proper language

Task 1

1 Questions about personal sleep habits. There are two functions for asking the questions: i) a topic-related question may help lead audience to this talk; ii) it is more attractive and interesting for audience.

2 There are three major points the lecturer will cover in his lecture: i) the problem of sleep deprivation; ii) the causes; and iii) the effects. The lecturer introduces the main points of his lecturer in the very beginning so that the audience can follow it easily.

3 Let’s start with the problem of sleep deprivation.

First, what are the causes of sleep deprivation?

Now I’ m going to move on to the effects of sleep deprivation.

Another consequence of sleep deprivation is car accidents.

4 To make his lecture more concrete and understandable.

5 How many of you would say that… that you don’t go to sleep when you should because of the TV or the Internet?

So now, what are the effects of sleep deprivation? The most common effect is, of course, sleepiness during the day. Let me ask you…When do you feel sleepy?

The rhetorical questions may involve the audience into his lecture.

6 Let’s, well, yeah, now, so, you, as you can see. The colloquial expressions may narrow the distance between the lecturer and audience.

7 The style is more informative and colloquial. The language is easy. For example, the structure and the vocabulary are simple. Many transitional words are used to guide the audience. For example, personal experiences and stories are preferred to make the talk more interesting. Repetition is often employed to make his lecture more understandable.
