Last time we discussed the protection of the environment. What is the problem? (The problem is that people throw away too much litter.)
What can we do in this situation? (We can recycle the litter.)
Do you throw the rubbish away or put it into the bins? (Asforme, I put the rubbish into the bins.)
Are there different bins in our streets? (No, there is usually one bin for any kind of the rubbish.)
Let's continue working on the text. Your homework was to work out the meanings of words unknown to you. I hope, you were lucky to do it. Read the sentences with such words and translate them.
See ex. 42, p. 51. Do the task in writing discussing it in pairs.
Litter — rubbish; to get rid of — to throw away; to make — to produce; the packaging — the wrapping; to save — to protect; to damage — to hurt; terrible — horrible.
To look worse — to look better; impossible — possible; cheap - expensive; to destroy — to make; dirty — clean; to remember — to forget; fortunately - unfortunately.
Answer the questions in ex. 43, p. 51 working in groups. Then report to the class what you have found out.
People can burn rubbish or recycle it instead of just throwing it away.
Recycling is important nowadays because many things that we throw away can still be useful. Recycling saves trees and energy and protects the environment from pollution.
Only 4% of recyclable material is actually recycled because it is expensive.
Yes, there are. People usually take waste paper, glass, metal and plastic there.
Packaging is necessary because it keeps food Clean and fresh.
Some packaging becomes litter because, people just tear the wrapping off the sweets and throw it away, or they drop their cigarette packets and cans of drink without a thought.
Litter is so dangerous in the countryside because it remains in the fields and on the roadsides.
Yes, it is. Unfortunately people in our town/village throw away litter such as cans of drink or cigarette packets. Sometimes our teachers organize a "clean-up day" to clear all the litter outside the school. '
I see that you are tired. Stand up. Have a rest.
V. Обучение грамматике
You already know two types of the Conditionals: second and" third. Say what period of time the second Conditional refers to. (It refers to the present or to the future.)
What about the third Conditional? (It refers to the past.)
Are they real or unreal Conditionals? (They are unreal Conditionals.)
Sometimes you can find combined sentences. They are called mixed Conditionals. Read the necessary information in ex. 44, p. 52.
Now it's your turn to work with mixed Conditionals. Have a drill. Look through the task of ex. 45, p. 52. Do it one by one.
