3、tunity to see the whales close up best.2.Do you think it is important to carry out research on whales and other sea creatures?This research helps us learn more about the wonderful world we live in,and about these amazing creatures so that we can better protect them.When people talk about a series of

4、 actions or events happening in sequence of time,they often use certain words and phrases,such as first,next,then,after that,later,and finally.Listen to the head researcher talking to the campers at the end of the day.What three things were the campers asked to do?P301._2._ 3._What three things were
