[教学难点]

How to use the structure in the proper situation.

[教学方法] Observation. summary ,discussion and practice.

[教学用具]

Computer，PPT，blackboard [教学过程] Step One.

Lead-in

Teacher:Have you ever been to the countryside?

Ss:

Yes , I have. / No , I haven’t.

Teacher:

Have you ever grown any plants ? If so , what did you do to grow them? If not , what kind of plant would you like to try growing? How would you grow it?

Ss:

There are four steps: Ploughing is the first step, and planting is the second step…

设计理念：首先抓住学生比较喜欢的话题设置情境，提问学生是否去过乡下，让学生对此话题更充满兴趣。接下来通过回答如何种植作物导入V-ing做主语和宾语。

Step Two.

Show and Observation Teacher :

Show some English sayings including V-ing form. 1.

Constant dripping wears away stone.水滴石穿

2.

Saying and doing are two different things.说和做是两码

事

3.

Doing is better than saying.空言无补。

4.

A good beginning makes a good ending.善始者善终。

5.

It is no use crying over spilt milk.覆水难收。

Step Three. Discovery and Extraction(提炼) Ask students to pick the same structure out from the sentences .Then let the Ss summarize its structure of“V-ing form”by themselves.

设计理念：让学生自己主动发现相同结构的规律，然后切入本课正题。通过板书把学生发现的语法结构展示出来。

Step Four.

Comparison ,Understanding and Summary

Show some pictures and finish the sentences together with the students.

Teacher: 1.What kind of sentence consituent(句子成分)is it used as?

2.What should we pay attention to when we use V-ing form as subject and object?

3.What kind of verb or prepositional phrase is followed by V-ing form ? 一、动词-ing形式作主语

1. 动词-ing形式作主语，表示一般或抽象的习惯性行为，谓语动词用单数。如：

Reading aloud is very important for us to learn a foreign language.

Going to bed early and getting up early is considered to be a good habit. 2. 在一些句子中，常用it作形式主语放在句首，而把真正的主语放到句末。

如：

It is very important remembering others’ names.

二、动词-ing形式作宾语

1. 有些动词后只能跟动词-ing形式作宾语，而不能跟动词不定式作宾语。有此用法的动词有：allow, advise, admit, appreciate, avoid, bear, consider, delay, deny, enjoy, escape, finish, forbid, imagine, keep, mind, mention, permit, practice, quit, risk, suggest等。如：

My mother advised asking a doctor to come and examine my eyes.

We’re considering paying a visit to the Science Museum.

注意：在allow, advise, forbid, permit后直接跟动名词作宾语，如果有名词或代词作宾语，则构成“allow／advise／forbid／permit ＋名词／代词＋不定式（宾语补足语）”之形式。如：

We don't allow smoking here．

We don't allow anybody to smoke here．

2. 有些动词后既可跟动词-ing形式作宾语, 也可跟动词不定式作宾语, 但用法和意义都有所不同。这些动词是：remember, forget, stop, regret, try, mean等。如：

I remember meeting her at a party once.

Please remember to close the door when you leave the room.. 3. 动词-ing形式用在动词need, want, require等后表示“需要”时, 用动词-ing形式的主动形式或者用不定式的被动式表示被动意义。如：

The carpet really wants to be cleaned. =

The carpet really wants cleaning. 4. 动词-ing形式作介词的宾语。要特别注意: be / get used to, look forward to, pay attention to, stick to, devote to等中的to都是介词而不是动词不定式符号。如：

My father is used to going to bed late and getting up very early.

I’m looking forward to receiving your reply.

设计理念：学生观察提炼此语法结构之后可能会产生疑惑，在什么情况下才用此语法结构，然后通过句型操练让学生清楚此语法的具体使用方法，并引出其

他用V-ing form做宾语的情况，让学生通过比较、观察总结其使用方法。

Step Five.

Exercises I. Complate the sentences correctly. 1.Would you mind ________ (turn) down your radio？

2.__________(throw) waste into a river will cause the fish to die. 3.The windows haven’t been cleaned for a long time. They need ____(clean). 4._____________(invite) to the party was a great honour to the family.

设计理念：语言学习首先要从初级的补全句子开始进行机械操练，使学生在练习题中熟练此结构及用法。

II. Rewrite the following sentences using the –ing form as the subject. Example:

1. It is necessary to get water from wet to dry places.

Getting water from wet to dry places is necessary. 2. We don't allow anybody to waste water here．

We don't allow wasting water here．

3. The big hall needs to be cleaned.

The big hall needs cleaning. 4. In the countryside it is not as easy to do research as in the city.

Doing research in the countryside is not as easy as in the city. 5. To get rid of hunger is very important for some African countries.

Getting rid of hunger is very important for some African countries.

设计理念：安排此项练习是为了让学生在应用中体会it 做形式主语的作用，以及不同动词加宾语的特殊情况，更熟练的掌握其用法。

Step Six.

Game-designing Discuss in groups what is your favourite sport in your spare time?(Attention: at least use 2 v-ing as subject or object.) Eg. Playing basketball is my favourite sport, I often practise playing it after class.

设计理念：语言的中级阶段应该是脱离并高于机械练习。通过以上操练，让学生掌握基本结构和v-ing的作用后，再让学生用新学的语法结构联系生活实际从头脑中输出完整的句子，以此加深对此结构的理解，真正做到由点到线的应用。

Step Seven. Consolidation

Suppose Yuan Longping is coming to our school to give a speech here, as a

member of the Students’

Union, you should show him around the school and introduce the school to him, write an introduction beforehead,(at least use 5 v-ing as subject or object.)

设计理念：只对学生单一的说练来运用新的语法结构还依然不完善，还要通过另外一种输出方式，即写作，来更高境界的运用所学语法，真正做到由面到体，并以此来检验学生是否真正掌握了本课重点。

Step Nine. Homework

1.

Revise the grammar. 2.

Do the exercises in the paper

设计理念：经过一节课的观察、发现、理解、总结、演练、联系生活实际，写作等一系列环节之后，辅以作业使学生在课下时间能够慢慢消化吸收此语法结构—定语从句。
