UNIT ONE: Teaching the Auxiliary Verbs of Néng and Huì .
Chinese grammarians and textbook authors have long made the observation that both auxiliary verbs and have the meaning of "can, be able to", though they each can have other meanings under other circumstances (Li 1981, Liu 2001, Wu 2006). This unit focuses on one specific characteristic of and 会;namely, and can be distinguished based on whether the ability being described refers to "ability acquired from learning" or "ability not acquired from learning". (Liu 2001, p.184).
Give this information to your students and ask them to do TASKS 1 and 2 below in small groups of three or four.
TASK 1: For each dialogue between Speaker A and Speaker B below, indicate if and denote "acquired ability" or "non-acquired ability" by selecting one of two choices with a √.

Dialogues
Acquired ability
Non-acquired ability
1
A: 他会开车吗? Can he drive?
B: 不会。他没有学过开车。 He can't. He hasn't learned how to.


2
A: 累了吧?要不要休息一下? Tired? Want to take a break?
B: 不累。我还能再走一个钟头。 No. I can walk for another hour.


3
A: 你会说英文吗? Can you speak English?
B: 会说一点。说得不好。 I can speak a little. Not very well.


4
A: 雪这么大,不能去上课了吧? The snow is heavy. You can't go to class, right?
B: 能啊。开车小心点就行了。 Of course I can. Just drive carefully.


5
A: 他会游泳吗? Can he swim?
B: 会。他游得还不错。 Yes, he can. He can swim pretty well.


6
A: 他的饭量怎么样? How is his appetite?
B: 好极了。一顿能吃三碗饭。 Excellent. He can eat three bowls of rice each meal.



TASK 2: Based on the findings above, determine if the following statements are correct or incorrect. For each statement below, select one of two choices by checking one box with a √.
Statements
Correct
Incorrect
1. is used to describe ability acquired from learning.


2. is used to describe ability not acquired from learning.


3. is used to describe ability acquired from learning.


4. is used to describe ability not acquired from learning.


5. means "to know how to"


4. means "to know how to"



After the students have completed TASKS 1 and 2, have each group report its findings. Ask each group to justify its conclusions. The correct answers should be:
· is used to describe ability acquired from learning. In Dialogues 1, 3 and 5, is used because one must learn to drive, speak English, and swim in order to acquire the ability to do so respectively.
· is used to describe ability not acquired from learning. In Dialogues 2, 4 and 6, is used because the ability to walk for another hour, go to school in a snow storm, and eat three bowls of rice does not require learning.

The validity of this initial observation and conclusion about the communicative functions of and can be further tested by critically examining another dialogue below. Have the students work on TASK 3 below.

TASK 3: Now examine the dialogue below and check (√) each of the statements below the dialogue as either true or false.

A: 在上海开车的人很多。 There are many people driving in Shanghai.
B: 是啊。只要有執照就能開車。 That's right. As long as you have a license, you can drive.
A: 可是能開車的人不一定會開車。 But those who can drive don't necessarily know how to drive.
B: 所以交通事故经常发生。 Therefore, there are often traffic accidents.
Statements
True
False
1. Either or can be used—without causing any meaning change—in B: 是啊。只要有執照就 開車 That's right. As long as you have a license, you can drive. , or inA: 可是 開車的人不一定 開車。 But those who can drive don't necessarily know how to drive.


2. has a more general meaning of "can" while has a more specific meaning of "know how to".


3. When is used to mean "can", there is generally a reason given for the speaker's abilityor lack of abilityto do something.


4. and cannot be used interchangeably in the dialogue above without causing any meaning change.



After the students have completed TASK 3, have each group report its findings. Ask each group to justify its conclusions. The correct conclusions should be:
· has a specific meaning of "know how to", as in "know how to drive".
· has a more general meaning of "can". In general, when is used, a reason is given to explain the speaker's ability—or lack of ability—to do something. For instance, it is pointed out in the dialogue above that one can drive because one has a license to drive. Whether or not one knows how to drive well is a different matter.
· For the reasons mentioned above, and cannot be used interchangeably in this dialogue without causing any meaning change.

TASK 4: Now, ask the students to compare and with the English word can. First, ask the students to discuss the similarities and differences between / and can by answering the following questions:
1. Do English speakers generally use different words comparable to and to describe different kinds of "ability"? Have the students examine the English translations of the dialogues in TASK 1.
2. Under what circumstances do speakers of English use can and know how to to specify different kinds of "ability"? Have the students examine the English translation of the dialogue in TASK 3.
After the students have completed TASK 4, have each group report its findings. Ask each group to justify its conclusions. The correct conclusions should be:
· The English word can is generally used to convey the meaning of "can" and "know how to".
· In conveying the meaning of "know how to", Chinese uses the word . In conveying the general meaning of "can", Chinese uses .
· An English speaker learning Chinese must remember to always differentiate the general meaning of "can" and the specific meaning of "know how to" by using and respectively.
· An English speaker learning Chinese must remember NOT to use in all instances to describe ability.

ASSESSMENT: Input and Output Tasks
To assess students' ability to comprehend and interpret the meaning and functions of and accurately as well as their ability to use and appropriately in interpersonal communication, I propose two types of assessment tasks. First, students will do an interpretive input activity—TASK 5. In this task, students will read a paragraph in which or will be needed to fill out the blanks in it. This paragraph represents "comprehensible input" (Krashen 1982)—language that contains structures slightly above the learners' current level of competence but can be understood through use of context, world knowledge and other linguistic and extra-linguistic cues. Such comprehensible input allows learners "to go for meaning first, and, as a result, acquire structure as well" (Hadley 1993, p.51).
To assess students' ability to use and appropriately in interpersonal communication, ask the students to complete an output task—TASK 6 below—which requires them to create a dialogue using and in the dialogues. Afterwards, ask the students to justify their answers.


TASK 5: INTERPRETIVE COMMUNICATION. Fill out the blanks in the paragraph below with or , following the rules of their usage.
有人认为人人都­­­­­ 学外语。可是小王学了三年的法文,还是不­­­­­ 说法文,也不­­­­­ 用法文写文章。可是小王­­­­­很 努力,也 ­­­­­ 吃苦, 相信以后一定­­­­­ 学好法文。
The purpose of this task is to assess students' ability to distinguish and —based strictly on the rules they have learned so far; namely, denotes "general and non-acquired ability", and denotes "acquired ability". It is best to focus on assessing knowledge of this first rule at this time before delving into other factors affecting the use of and 會,including the notion that either or may be used to fill out some of the blanks due to various contextual interpretations. The key to this task is:
有人认为人人都­­­­­ 能 学外语。可是小王学了三年的法文,还是不­­­­­ 会 说法文,
也不­­­­­ 会 用法文写文章。可是小王­­­­­ 努力,也 ­­­­­ 吃苦, 相信以后
一定­­­­­ 会 学好法文。
Below are some recommended Assessment Rubrics: 5=Excellent, 4=Very Good, 3=Good, 2=Weak, 1=Very Weak. Teachers can add more rubrics to this list.
1. Comprehension and interpretation of meaning of paragraph
2. Appropriate use of and
3. Justification for use of and : use of contextual clues

TASK 6: INTERPRESONAL COMMUNICATION. Ask the students to work in pairs to translate the dialogue below. Use­ and according to the rules of their usage.
Situation: Two friends discussing their summer plans.

A: A few of us have applied to a summer study abroad program in China. Can you go to China, too?
B: Afraid not. I have to work this summer; so I cannot go.
A: You should come with us. None of us can speak Chinese. But you can speak and write in Chinese. When we go out to play, you can help us.

B: Actually, I can only speak a little Chinese. I can't write in Chinese at all.
A: Aside from working, what else do you plan to do this summer?
B: I think I can find some time to take some swimming lessons.
A: Being able to swim is fun! But I am too busy this summer, so I can't take lessons.
A: But you are going to China! In China, you can go to many places and learn many new things.
B: That's right. Last year, because I did not have the money, I could not go. This year I can go, so I must go.
A: You must go. After this summer, you will be able to speak Chinese.

While allowing for some linguistic and stylistic variations, in terms of the substantive content of this dialogue pertaining particularly to the use of and , the translation of this dialogue should be close to the one below:
A: 我们有几个人申请了一个暑期在中国学习的项目。你也能去吗?
B: 恐怕不行。今年夏天我得工作,所以不能去。
A: 你应该跟我们一起去。我们都不会说中文。但是你会说、也会写中文。我们出去玩儿的时候,你就能帮我们了。
B: 其实我只会说一点中文。我完全不会写中文。
A: 除了工作以外,你今年夏天还打算做什么?
B: 我想我能找出一些时间去上游泳课。
A: 会游泳真好玩儿。我今年夏天太忙,所以不能上游泳课。
A: 可是你要去中国啊!在中国,你能去很多地方、学很多新的东西。
B: 是啊。去年我没有钱,所以没去。今年我能去,所以一定得去。
A: 你一定得去。过了这个夏天,你就会说中文了。
