→ Step 2 Lead-in
Show the picture to the students and ask them to pay attention to the word “help" in these two sentences. Ask the students what parts of speech of “help” in these sentences are.
1. “Help” in this sentence is used as a verb。

2. I n the second sentence “help" is used as a noun.
In this period，we will learn some words, which have several parts of speech。

Now look at the short dialogue。

In the passage “Fog", we learned a story about a blind man's helping others in a foggy day. Polly is telling others about her experience.
Look at the picture and pay attention to the conversation.
A：He met me in Park Street and walked me the rest of the way home.
B：That was nice of him。

Why didn’t you invite him to come in and rest?
A：I did，but he wanted to go and find more people to help.
Ask the students this question:
Who can find the word which has two parts of speech in these dialogues？
Suggested answers:
“Rest” has two parts of speech。

In “the rest of the way”，rest is a noun。

In “come in and rest”，rest is a verb.
Like “rest" in the dialogue, many words in English have more than one part of speech. In some cases，different parts of speech （usually a noun and a verb) have the same spelling but different meanings.
→ Step 3 Grammar focus
As a matter of fact, we have learned so many words like “rest” which has more than one part of speech。

Traditional grammar classifies words based on ten parts of speech：the verb, the noun, the pronoun，the adjective, the adverb，the preposition，the conjunction，the numeral, the article and the interjection. Each part of speech explains not what the word is，but how the word is used。

In fact，the same word can be a noun in one sentence and a verb or adjective in the next. The following
examples show how a word's part of speech can change from one sentence to the text。

Books are useful。

In this sentence, “books” is a noun, the subject of the sentence。

Dick waited patiently while Bridget was booking the ticket.
Here “book” is a verb，and its subject is “Bridget"。

We walk down the street。

In this sentence，“walk” is a verb, and its subject is the pronoun “we”.
The mail carrier stood on the walk.
In this example，“walk” is a noun, which is part of a prepositional phrase describing where the mail carrier stood。

Now, I’ll give you five minutes to discuss with your partner and try to find more examples. Divide the students into several groups and let them have a competition. The group who think out the most examples will be the winners。

After the competition, the teacher can explain the rules to the whole class（we can classify them into several kinds）:
1)有大量的动词转化为名词，有时意思没有太大变化.如:
Let me have another try. 我来试一试.（名词）
Let me try once more. 让我再试一次。

（动词）
I like a quiet read after supper.
晚饭后我喜欢静静地看一会儿书。

（名词）
I read quietly for a while after supper。

晚饭后我静静地看了一会儿书。

(动词）
This kind of nouns usually forms a phrase with some verbs，such as “have, make” and so on.
E。

g。

have a look （chat, talk, swim，rest，try, quarrel, smoke，lie, read, dream, run，fight，walk，ride, shave, taste），make a study (guess, visit, call, survey，jump，demand，show, an attempt，an attack，an advance).
2) Many nouns can also be used as verbs, and many nouns which refer to the objects are usually used in this way.
E. g。

n。

v。
