Enviro-Loo
点击查看大图
Today we have an environmental theme on Study English, but it’s an environmental story with a difference.

We find out about a new toilet system that has been developed to save the local environment in a Tasmanian park.

We’re going to be looking at how to talk about ‘processes’, so listen carefully to David Holman talk about his new environmentally friendly toilet.

The liquid waste comes from the toilet behind me. There’s a containment vessel for
the solids. From the bottom of the solids you drain off the liquid and it comes down
here down this pipe.

OK. The pipe tips into this tipping bucket arrangement, and what this does is it fills up to a point, and then it suddenly tips and that will measure each time it tips. So we can calculate the amount of liquid effluent that’s gone in.

As that fills up, you can see the towelling material here will come in contact with the effluent, the air is drawn in through these holes and will actually direct the air in onto the surface of the water, through the wick and out through the top.


OK, so David was talking about how his toilet, the Enviro-Loo, works.

He was describing a ‘process’. Today we’re going to look at the type of language you’ll need to describe processes.

We’ll listen to David again. This time, listen out for the types of verbs he uses.

The liquid waste comes from the toilet behind me. There’s a containment vessel for the solids. From the bottom of the solids you drain off the liquid and it comes down here down this pipe.

OK. The pipe tips into this tipping bucket arrangement, and what this does is it fills up to a point, and then it suddenly tips and that will measure each time it tips. So we can
calculate the amount of liquid effluent that’s gone in.



David uses a variety of verbs and tenses. But mostly he uses the ‘simple present tense’.

The ‘simple present’ is often used to describe processes and procedures.

Let’s look at some examples.

The liquid waste comes from the toilet behind me.

OK. The pipe tips into this tipping bucket arrangement, and what this does is it fills up to a point and then it suddenly tips.


There’s also another, more formal way of describing processes.

That’s using the ‘passive voice’.

In academic writing, it’s common to use the ‘passive voice’ for actions in a process or procedure. When you use the passive voice, your writing becomes impersonal and distant. This is more formal, and is often more suitable in an academic setting.

Listen for a passive verb here.

As that fills up, you can see the towelling material here will come in contact with the effluent, the air is drawn in through these holes.

He says ‘is drawn in’: ‘the air is drawn in’.

Notice there is no ‘subject’, no person or thing doing the action, it is just done. This is called the ‘passive voice’.

This highlights the process or action, rather than the person or thing doing the action.

The passive is used when the important thing is not who did the action, but the action
itself.

This is true when you are describing processes. The process is the same, no matter who is doing it, so we choose the passive voice.

Let’s look at bit more closely at how the passive is formed …

Passive verbs are formed by using the verb ‘to be’ plus the ‘past participle’ of the verb.

Let’s look at the verb to ‘draw in’, to bring something in.

The past participle is ‘drawn. This is an irregular past participle.

So the passive form is ‘to be drawn in’.

The different forms of the passive vary according to the action, and when the action happened.

今天要掌握的内容是 ACTIVE AND PASSIVE VOICE 主动语态和被动语态
先来看看主动语态~
Active voice: subject of the sentence does the action and is called the agent
句子的主语做出的行为,所以也叫agent~
ABC television screened the English language series.
subject/agent主语,行为者 object宾语
active form: subject/agent + verb + (+object)

Passive voice: subject receives the action, shifting the focus from the agent to the object主语是接受行为的对象,焦点从agent转向宾语~
The English language series was screened by ABC television.
Subject agent
passive form: subject + be + past participle (+ by + agent)
