Task-based Language Teaching Method
课时安排:
One period
教学设计:
Step Ⅰ Lead-in
Activity 1 Look at the sentences from the reading passage.
a.It’s just typical that my journey is on one of the oldest lines,as well as one of the deepest.
b.My office is only on the third floor of the building,so quite low.
Activity 2 Compare them with the following sentences and answer the questions.
c.It’s just typical that my journey is on one of the oldest lines, as well as one of the deepest lines.
d.My office is only on the third floor of the building,so it is quite low.
1.What has been left out in sentences (a) and (b)
2.Why does the author leave them out
Suggested answers:
1.“Lines” has been left out in sentence (a),and “it is” has been left out in sentence (b).
2.The author leaves them out to avoid repeating the word or expression that is too obvious,and to make the sentences more concise.
Step Ⅱ Analysis and identification
Activity 1 Read the paragraph and find out what words have been removed before or after the underlined words.
Technology isn’t the only way to forecast the weather.Nature has its ways,too.Unusual animal behaviour,for example,can indicate whether it’s cold,wet weather that’s on the way or a hot,dry period.If fish are jumping higher than usual or frogs are croaking more loudly,it may rain.And next time you look up at the sky,don’t just look for rain clouds,but also for birds.If they are flying low,grab your umbrella.It is also said that mice and snakes head for safer ground several days before an earthquake,while dogs avoiding the beach may be a sign that a tsunami is approaching.Of course,although these things may suggest something bad is going to happen,they won’t tell us when and where.So,for accurate and reliable predictions,it’s best to check an official,scientific report.
Activity 2 Fill in the blanks.
省略(Ellipsis):英语中有时为了避免重复,使语言简练紧凑,在不影响句子结构和意义的前提下,往往省去一个或多个句子成分或词语,这种语法现象称为省略。
例如:It’s typical that my journey is on one of the oldest lines,as well as one of the deepest (lines).
一、简单句中的省略
在简单句中,可省略主语、谓语或谓语的一部分、宾语等,有时甚至同时省略若干成分。例如:
(1)(You) Hand me the book over there.
(2)(Is) Anybody against the suggestion
(3)—What do you think made David so happy
—Passing his driving test(made him happy).
二、并列句中的省略
在并列句中,如果后面的分句与前面的分句中有相同的成分,那么后面分句中相同部分常被省略,以避免重复。例如:
(1)I arrived here today,and (I) must stay here one or two weeks.(省略主语)
(2)I asked John to go,but she (asked John) to stay.(省略谓语和宾语)
(3)Knowing is one thing,and believing (is) another thing.(省略系动词)
(4)In my class,boys like sports while girls do not (like sports).(省略谓语和宾语)
(5)My father looked angry,and I certainly was (angry).(省略表语)
三、复合句中的省略
1.定语从句中的省略
在限制性定语从句中,可省略在从句中作宾语的关系代词that、which、whom、who;但如果关系代词作介词的宾语,且介词置于关系代词之前时,则不可省略关系代词。例如:
(1)That is the film (which/that) we watched last week.
(2)Tom isn’t a man (whom/that/who) you can believe in.
(3)The athlete to whom you talked is a famous runner.
【注意】 当先行词为the way且在从句中作状语时,从句用that或in which引导,that或in which也常被省略。
We admired him for the way (in which/that) he faces his difficulties.
2.状语从句中的省略
在状语从句中,如从句的主语与主句的主语一致并且从句的谓语中又包含be动词时,可以省略从句中的主语和be。另外,若状语从句为it/there+be结构时,也可省略it/there+be。例如:
(1)While (I was) in Hangzhou,I paid a visit to the West Lake.
(2)The computer is of no use unless (it is) repaired.
(3)Although (he is) still young,he knows a lot.
(4)Hand in the work tomorrow if (it is) possible.
3.宾语从句中的省略
(1)在宾语从句中,连词that一般可以省略。
(2)但在“介词+形式宾语it+宾语从句”这一结构中的that不可省。
(3)宾语从句中包含that引导的两个或两个以上的并列宾语从句时,通常只有第一个that可以省略。例如:
①I don’t believe (that) Mike has joined the army.
②You may depend on it that I shall always help you.
③Lisa told me (that) she was ill and that she couldn’t go to school the next day.
【注意】 有时可用so或not代替上文的内容。例如:
(1)Work hard.If not(If you don’t work hard),you will fail in the exam.
(2)—Do you think Mr.Green will give us help
—I hope so.(I hope he will give us help.)
【拓展】 动词不定式中为了避免重复,常省去前面出现的相同部分,而只保留不定式符号to;如果在省略的不定式结构中含有系动词be或助动词have/have been时,be/have/have been这些词要保留。例如:
(1)I asked my friend to have a drink,but he didn’t (have a drink).
(2)—Are you a teacher now
—No,but I used (a teacher).
Activity 3 Practice
Remove words from the news report to make it more concise.

In August 1949,the Landes region of South-west France faced a major 2. that lasted almost a week.Some 500 km2 of forested land was burnt and 82 people killed.Even today,it is considered one of Europe’s most deadly forest fires.
The winter of 1950 to 1951 came to be known as the Winter of Terror when over 600 3. struck towns and villages in the mountains of the Swiss-Austrian Alps.Caused by exceptionally heavy snowfall within a short period of time,they destroyed buildings and forests,and claimed over 256 lives.
In 1960,Chile suffered the strongest 4. to be recorded in the 20th century.The shock is generally agreed to have had a magnitude of 9.5.It caused a(n) 5. with waves of up to 25 metres affecting places as far away as Hawaii and Japan.
A(n) 6. hit Iran in February 1972,causing a week of extremely low temperatures.Winter storms brought as much as 7.9 metres of snow in the south of the country, resulting in the deaths of about 4,000 people.
In July 2011,a(n) 7. struck East Africa. It was said to be the worst in 60 years,and not a single drop of rain fell for almost a whole year.It led to a severe food crisis and threatened the livelihoods of more than 9.5 million people.

Activity 1 Extreme weather conditions
For thousands of years,people have been trying to predict the weather.In China during the Shang Dynasty,people recorded weather forecasts on animal bones and tortoise shells.Centuries later,in Greece,the philosopher,Aristotle wrote his theories about how weather conditions formed.Weather forecasting advanced over time,with more and more instruments to measure temperature,humidity and air pressure.Today,satellite data and computer technology help scientists predict the weather more precisely and comprehensively.
