教学建议

单元内容分析

本单元主要教学现在完成时态,围绕“The lost book”开展教学活动。学习了有关“借物和寻物”的交际用语以及到图书馆借阅图书及相关事项,着重使用了“Have you got…”这种句式,通过对话,教学了现在完成时态的用法和构成,重点分析过去某个动作对现在造成的影响或结果。学习了过去分词的构成和动词加一ed后的读音,if引导的从句中时态的使用,同时还学习了一些同义词、近义词的用法与区别。

ago 与before

ago与before 是两个表示“以前”的概念的单词。在用法上,它们的区别是较大的。

1)ago和一般过去时的动词连用,表现现在以前的过去时间,它不能用于完成时态,例如:

Your friend was here a week ago, wasn't he? Of course he was.

before可以和完成时态连用,也常常与never连用,表示在早先或过去的某时间的“以前”。

例如:

I never met him before. He's new to me.

下面以three years ago和three years before为例来进行比较。three years ago用于过去时态,

表示从今天算起的“三年以前”;而three year before用于过去完成时态,表示从三年以前算

起的过去。试看下面的比较:

A. I met him three years ago. We've been friends for 3 years.

B. I had met him three years before. I met you in 1992.

句A表示:“(从今天算起)三年前我遇见过他。”句B表示:“(从三年前追溯起)三年前我遇见过他一次。”

2) 另外before与ago单纯在形式上的区别是before可以单独使用,ago必须与别的表示时间的词连用。例如:

I have read it before. It is a very good novel.

I read it 3 years ago. But I can't remember everything about it.

例  Have you found the book? Yes, I _____it five minutes_______.

A. have found, before      B. found, before

C. has found, ago          D. found, ago

解析 ago表示从现在算起的多少时间以前,用于一般过去式的句子中,before则表示从过去看的某时间以前或泛指以前,常见于完成时态。从本句的答语“我5分钟前找到的”中,可以判断是从现在算起的五分钟前,故选D。

full与fill

(1)fill v.把……填满,常与with连用。如:

Please fill the bags with rice. We've got to take them to the poor family in the village.

fill也可以表示状态。相当与 be filled with。如:

Smoke filled the room. =The room was filled with smoke.房间里浓烟弥漫。

(2)fill in填入、填写、塞满,如:

–Please fill in your telephone number and your name.

–OK, But may I borrow your pen?

–What shall I do if I want to find a job here?

–Fill in the application form.

(3)full adj. 满的,充满的。其结构是be full of=be filled with,如:

The basket is full of apples. =The basket is filled with apples.Enough for all of us.

The bag full of books is mine. Please carry it for me, It's too heavy.

lose与 miss

1)两者都表示“丢失”。lose的语气较强,含有丢失后不易找到;miss含有“发现丢失”之意。在很多情况下两者可换用。例如:

You said you have lost your watch. When did you miss it? 你说把手表丢了,你什么时候丢的?

2)lose通常用过去分词(lost)作定语或表语;而miss则用其ing形式(missing)作表语或定语。例如:

Is there anything missing (Is there anything lost) ?

Nothing, so far as I know.

on与about

二者都是介词,意为“关于,论及”等,一般情况下,二者可以互相替换,但二者有点区别:about常用于简单的或浅显的论述等,是一般用语,多用于讲故事,谈话;思考等;on多用于系统论述或专题讲演、论著等,具有学术性,如:

The teacher told us a story about Lei Feng. It's very moving.

He will give us a talk on the history of the Party.他将给我们做个关于党史的报告。

正误例析

今天下午我们将听一个关于非洲历史的演讲。

误:We're going to listen to a lecture about African history his afternoon.

正:We're going to listen to a lecture on African history this afternoon.

析:介词about和on都可以作“关于”解。on表示一本书、文章或演讲是严肃的、学术性的,可供专门研究这一问题的人们参考;about则表示其内容比较通俗,一般人都可阅读。

the lost books 丢失的书。

The book was still missing.书还是找不到。

lost=missing丢失的。英语中单个分词(包括现在分词和过去分词)也能作定语用,它们一般放在名词的前面。又如:a stolen car一辆失窃的汽车;a broken wind。一扇破的窗;the giving name教名,名;a surprised girl一位感到吃惊的女孩。

come up with

come up with=find or produce (an answer)意为“提出,提供”,它是由动词和介词一起构成的短语动词。它的另一个意思是“赶上”。例如:

I hope you can come up with a better plan than this. 我希望你能提出个更好的计划。

We shall have to work hard to come up with them. 我们要努力工作,赶上他们。

类似的词组有:

catch up with  come in for pay for

pay for意为“给……报酬”,“付款”。常见句型有:(1) pay for+货物,(2) pay+名词/代词+for+物。例如:

How much did you pay for that book?那本书你付了多少钱?

I'll pay you five yuan for it.我将为此给你五元钱。

I'm afraid can't pay you anything for it.我恐怕不能为此给你任何报酬。

She used to be a Chinese teacher. 她以前是一位语文老师。

used to意为“过去经常”,它只有过去式,用于各种人称的单、复数,表示过去存在的,

但现在已经停止的情况或习惯,后接动词原形。例如:

They used to come on foot,but they don’t do that again. They often come by bus. 他们过去经常步行来,现在不了。他们经常乘车来。

used to是表示过去经常重复的动作。在表示过去的习惯时,used to是比较规则的习惯,它与would不太一样,would侧重于叙述过去的光景,used to侧重于和现在相对照。

used to的疑问形式和否定形式可以用助词did或自身形成构成。美国人多用助动词  did;英国人多用used to本身。如:

–Did you use to go there?

–Yes, very often./No, only seldom.

I used not to like Beijing opera, but now I’m very fond of it.我过去不喜欢京戏,但现在非常喜欢。

他过去不常抽烟。

注意区分be used to所表示的意思是“习惯于……”,后跟名词或动名词,used是一个形容词。例如:

I’m not used to drinking.我不习惯喝酒。

She is used to running in the morning.她习惯早上跑步。

have got

I think I've got one.我想我有一个。

英语中表示“所有”用have,口语中常用 have got,其否定形式为haven't got,疑问形式为Have…got…?在美国英语中常使用don't have,Do… have…?例如:

I've got a book about chemistry. =I have a book about chemistry.我有一本化学书。

He hasn't got an umbrella. =He doesn't have an umbrella. 他没有雨伞。

–Have you got a pencil sharpener? =Do you have a pencil sharpener?

–Yes, here you are.

Have you got …?句型教学建议

利用初一学过的表示“拥有”的交际用语引出“have got”句型,讲解可先不讲解它的时态:现在完成时。

1.教师先和一个学生进行下面的对话。

T: Excuse me, Do you have a dictionary?

S: Yes, I do.

T: May I borrow them, please?

S: Certainly. Here you are.

T: Thank you.

教师接过dictionary后,说:

I have a dictionary

I have got a dictionary

并在黑板上板书:have got … ,然后让学生反复跟读。然后告诉学生这就是我们今天所要学的新句型:This is another way of saying “Do you have …?”

2.教师可逐一取出一些画片,边取边对学生说:I have got a …或拿出一些实物进行上面的句型练习。(a cup, a pen, a ruler, an eraser, a book等。)

关于课文The Lost Books教学建议

1.在教学本课的课文The Lost Books之前,先就本课Part 1的两个问题让学生进行回答,并写一段短文关于自己如何爱书,以及从图书馆借书的经历,然后让学生作演讲。如:

I like reading very much, because I’ve learned a lot from the book I read. I’ve bought many books and has got a small library of zoo interesting books. They are about many different subjects such as foreign languages, maths, history, geography and interesting stories. But my own library is still too small to meet my needs. I often borrow books from the school library. It has a great number of books. Many of them are very interesting. I’ve read so many interesting books in the school reading room. I’m a careful boy/girl. I never lose any library book. But some of my classmates do. When they are in such a trouble, I help them. I sometimes help them to buy new books. I even pick out the best books from my book shelves and give them to my friend in trouble. I believe a friend in need is a friend indeed.

2.让学生默读课文,回答练习册第2课练习1的8个问题。

3.把课文The Lost Books改成对话,由两个学生分别扮演grandma和 librarian,表演一遍,然后让学生轮换角色,以便更多的学生参加演出。实现学生自编——自导——自演——语言探究活动的过程。
