Grammar A

Part One Lead-in

In this unit, we learned a report about giant pandas. We know they are very lovely. But they are in danger. They may have many problems in the future.

Do you remember ‘the story of Xi Wang’.

Do you remember what problems they may have in the future?

Yes. If hunters catch a giant panda, they will kill it for its fur.

If farmers cut down trees and forests, giant pandas will have nowhere to live.

If people find baby pandas alone, they will often take them away.

Please remember:

If we do nothing, there will be no giant pandas in the world.

We can also say:

There will be no giant pandas in the world if we do nothing.

There will be a class visit to Beijing Zoo next week. Amy is writing a note to tell her parents why she wants to go. Please open your books, turn to page 65, help Amy complete her note. Let’s check the answers.

Part Three Rule out

Well, let’s work out the rule together!

‘if’引导的条件状语从句中用一般现在时表示将来，主句中用一般将来时。

Conditional sentences  (条件状语从句)

当我们把 ‘if’引导的条件状语从句放在句子开头时，我们需要在条件状语从句后用逗号。假如主句在开头，则没有必要加逗号。

We need a _______(comma, full  stop) after the ‘if’-clause when it is the first part of a sentence.

e.g.  If I go to Beijing Zoo, I will learn a lot about animals.

I will learn a lot about animals if I go to Beijing Zoo.  

Part Four Practice

Amy returned home from Beijing Zoo. Her father is asking her some questions about wild animals.

Open your books, turn to page 66, finish Part A3.
