Next we will listen to a conversation about Tina and Tara.Look at the picture on page 18 in your book. Tina and Tara are talking to the reporter. Listen to the tape carefully and pay attention to what they are talking about. They are talking about themselves, right OK. Now look at the two columns and read the headings please：－er，－ier and more. In the conversation, some words they say end in －er or －ier, some words they add more ahead .Listen carefully again and write the －er and －ier words in the first column and the words that use more in the second column.
Now look at the blackboard.Please pay attention to the word “funny”．When a word ends in “y” ，the “y” changes to an “i” when you add“－er”. That is “funnier”. And look at these two words：outgoing and hard－working.What is special about these words Yes, they have three to five syllables. When you compare things using words with three or more syllables，you use the word “more”．
VI.Practice
Listen to the recording again.This time write words in the boxes of 2b using the words from the list in activity 2a.Look at the example “more outgoing” in the box for Tina，which means Tina is more outgoing than Tara.
VII.Production
Just now we talked about the twins Tina and Tara. Next we are going on talking about Tom and Sam .How are Tom and Sam different Look at the chart in activity 2c，and work in pairs.You decide which one is A and which one is B .Student A in each pair look at the chart on page 18, and Student B look at the chart on page 81.You mustn't look at your partner's page.
For example, Student A reads the sample question to the class：“Is Tom smarter than Sam？”Student B look at the answer on your chart on page 81 and answers：“No, Sam is smarter than Tom.”Student B can ask another question，for example，“Is Sam taller than Tom？”Student A should answer：“Yes，Sam is taller than Tom.”Are you clear？OK, now please continue on your own.
The sample dialogue：

B：No, he isn't . Sam is smarter than Tom. Is Sam taller than Tom
A：Yes，he is .Does Sam run faster than Tom
B：No, he doesn't .Tom runs faster than Sam.Does Tom get up earlier than Sam
