Revision

Go over what we learnt in Lesson 2.

-How do you prefer to travel?

-How do you travel that way? Why?

Structure

Explain the pattern It + be + adj. + infinitive to the students. Use the sentences in the box.

Pattern in Use

An infinitive or an infinitive phrase can serve as the subject of a sentence. The infinitive can be placed first:

To take a plane is expensive.

To travel by train is cheaper than traveling by plane.

To play in the park is fun.

But it is more usual to place it first and move the infinitive or infinitive phrase to the end of sentence:

It is expensive to take a plane.

It is cheaper to travel by train than travel by plane.

It’s fun to play at the park.

It here has no meaning in the sentence. It is merely a placeholder or artificial subject. Aside from the verb to be, other verbs – including appear and seem – can be also used:

It seems impossible to walk to the city.

It appears advisable to compromise.

Activity A

Students should fill in the blanks, using the given words in the box. Make sure the students know the vocabulary first.

Answers: 1. faster 2. to take 3. expensive 4. to walk 5. to watch 6. to travel

Activity B

Have the students write their own answers using infinitive phrases.

Activity C

Ask the students to share what they wrote in C with their partner. Encourage the students to make a dialogue with their partners and practice it.

Words and phrases

Activity A

Have the students find the odd word in the word group.

T: Let’s find the odd word in each line. What is the odd word in the first row?

S: wheel.

T: Right. Train, plane, and bicycle are forms of transportation. But wheel does not fit this category.

Answers: 1. wheel 2. crowded 3. China

Activity B

Let the students write their own ideas.

T: Look at No. 1. Think about the things that have wheels. What things have wheels?

S1: Bicycles have wheels.

S2: Buses have wheels.

S3: Trucks have wheels.

T: Right. What about Number 2? What is sometimes crowded?

S4: Restaurants are sometimes crowded.

S5: Bus stops / Subway stations.

T: What is the fastest way to travel?

S6: The airplane is the fastest way to travel.

S7: A car is sometimes the fastest way to travel in the city.

S8: The train can be the fastest way to get somewhere if there isn’t an airport nearby.

Pronunciation

Activity A

Have the students listen to the recording and write the sound symbols for the underlined letters.

T: As a rule, -ng makes a sound of the second sound. Let’s think of words that have this sound.

S1: sing / wing /…

Activity B

Let the students circle the words with any of three sounds mentioned in A. After this, students should try to read the sentences with their partner.

Activity C

While the Ss read the nursery rhyme, the teacher can clap his or her hands or tap the desk rhythmically. Ask the Ss to say the rhyme with their books closed. While doing this exercise, the Ss should keep in mind the sounds they have learnt in A.

Revise the knowledge in Lesson Two.

Practice using the sentence pattern: It + be + adj. + to do sth….

Practice spelling the words.

Practice the ability of speaking the sounds correctly.

问题预测

应对措施本单元句型的总结与应用有些难。

注意讲解时让学生观察与总结：it 可以做形式主语，to do动词不定式也可作主语。

如：It is expensive to take a plane. = To take a plane is expensive.

( = Taking a plane is expensive. )

作 业Finish off the exercise on page 37.

板书设计Lesson 3

It + be + adj. + to do sth….
