高中英语词汇教学策略
语言学家Wilkings:
“Without
grammar,very
little
can
be
conveyed.
Without
vocabulary,
nothing
can
be
conveyed.”
语言学家LAUFER通过调查发现,外语学习者如拥有5000词汇量,阅读正确率可达56%,词汇量6400,阅读正确率63%,5000词汇量是个阅读所需词汇量的下限。美国语言学家DILLER作过一个统计,如果我们认得25个最常见的英文单词,那么平均每页纸上的字我们就会认识1/3,如果我们认识135个常用词,平均每页纸上的字,我们则认得50%,如果认得2500个单词,则为78%,如果5000个单词,则为86%,如果10000个单词,则为92%。他同时认为,外语学习者要想比较顺利阅读中等难度的文章,10000个词汇量是最基本的条件。他进一步指出,如果其中1000个单词是某一专业的专门词汇,那么,外语学习者在阅读有关该专业的文章时,阅读效率会更高.

新课程标准对词汇量的要求
五级:理解和掌握1500-1600个单词和200-300
   个习惯用语或固定搭配;
七级:学会使用2400-2500个单词和300-400个
   习惯用语或固定搭配;
八级:学会使用3300个左右的单词和400-500个
   习惯用语或固定搭配;
九级:学会使用4500个左右的单词和一定数量
   的习惯用语或固定搭配。
考试说明是这样描述的:英语单词的含义并非完全等同于词典中所标注的汉语意思,其含义随不同的语境会有所不同。能根据上下文正确理解灵活变化的词义,才算是真正初步具备了一定的阅读理解能力。

思考篇
Aim
of
teaching
(1)通过周密地控制或安排阅读材料中的词汇,
使学生接触?目标词汇;
(2)在生词自然出现时介绍词汇的意思;
(3)把词汇教学与其他教学活动结合?起来;
(4)单独的词汇教学活动。我们可以把这些方法作为高中英语词汇教学的“宏观策?略”来指导我们的实践。
实践篇
How
should
vocabulary
be
taught?:
语词汇教学研究者对词汇教学的途径取得了广泛的共识:
一是直接教学法,即以词汇教学为教学目标,对词的结构、意义和用法进行分析、讲解和操练。其优点是效率比较高,不足之处是学生从语境中猜测词义的机会较少。
二是间接教学法,即通过阅读、听说等活动,间接地达到扩大词汇量的目的。其优点是学生可以从多种不同的语境中学习词汇的意义和用法,缺点是不够集中,效率较低。
实践篇
How
should
vocabulary
be
taught?:
策略一:发掘同根词,掌握构词法常识。
策略二:分类强化
,关注特殊,重点突破。
策略三:重视熟词生义/新性适度拓展
策略四:重视具体语境下的词汇应用训练。
策略五:坚持不懈,持之以恒:每日5-10分钟;阅读中积累、增加词汇量;
策略六:词汇扩展本:对于复习阶段在阅读等中遇到的生词,要及时摘抄到词汇扩展本上,并不时复习、巩固。
策略七:
与时俱进,使用一些网络背单词工具,比如百词斩,扇贝打卡等。

词组教学为难点重点!
艾宾浩斯遗忘曲线
遗忘先慢后快的规律
4小时
9小时
1.及时强化原则
词汇记得快,忘得也快,能否及时复习关系重大。根据“艾宾浩斯遗忘曲线”的遗忘先快后慢的规律,学生记忆过的词汇在4小时,最迟在9小时内一定要复习一遍。培养学生养成及时的复习强化的习惯是词汇教学成功的关键。
Kachroo(1962)研究发现,要成功地记住一个生词,学生至少得连续遇到它七次,而Saragi
et
a1(1978)则指出不断地碰到一个单词16次之后,学生才能自然地记住它。在中国学生不具备广泛阅读的条件下,定期复习加深记忆显得更为重要。
2.学以致用原则
学以致用的四个主要途径
一、用刚学过的单词造句或在口语或写作中运用;
二、持之以恒的课外阅读;视频,美剧,歌曲。
三、做适量的词汇题和其他类型的典型试题;
四、适量的汉译英练习(Chinglish现象);
五、写英语日记。

Tom
is
in

state
recently
because
his
parents
got
divorced.
When

Tom

Tom’s
mother
was
an
elegant
lady
who
always
obeyed
his

orders.
I
used
to
envy
Tom
his

kind
mother.
Now,
as
his
best
friend,
I
feel
obliged
to
accompany
him
and
show
my
sympathy
for
him.
To
my
satisfaction,
Tom
recovers
from
the
terrible
mood
quite
soon.
