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.

part three rule out
well, let’s work out the rule together!
‘if’引導的條件狀語從句中用一般現在時表示將來，主句中用一般將來時。
conditional sentences  (條件狀語從句)
‘if’-clause
(simple present tense) main clause
(simple future tense)
if hunters catch a giant panda,             
 they will kill it for its fur.
當我們把 ‘if’引導的條件狀語從句放在句子開頭時，我們需要在條件狀語從句后用逗號。假如主句在開頭，則沒有必要加逗號。
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.
