《英语演讲稿》word版 本文内容:

1.

Good

morning,everyone.It’s

my

pleasure

to

give

this

presentation.My

name

is

zhang

qing.The

first

thing

I

want

to

do

is

asking

all

of

you

two

questions.One

is

when

do

you

get

up?The

other

is

when

do

you

go

to

bed?Well,I

hear

that

different

people

have

different

schedules.But

there

is

a

common

phenomenon

that

everyone

is

sleeping

at

night

and

working

during

the

day.That’s

what

I

am

planning

to

cover.

2.

My

topic

is

the

biological

clock

is

warning

you.Yes,I’d

like

to

address

you

on

the

biological

clock.Or

more

specifically,I

would

like

to

tie

the

subject

of

the

molecular

mechanism

of

controlling

circadian

rhythms.

3.

As

we

all

know,The

sunrise

makes.

The

sunset

but

the

rest.

This

is

a

phenomenon

of

the

circadian

rhythm

or

the

biological

clock.

4.

But

how

did

this

rule

come

from?How

does

it

work

in

gene?

5.

The

origin

of

this

phenomenon

is

very

interesting.

A

fruit

fly

that

sleeps

during

the

day

,and

during

the

night

howls

all

the

time

has

caught

the

attention

of

scientists.

After

the

further

research,it

was

found

that

this

unique

fruit

fly

is

losing

circadian

rhythm

due

to

the

mutation

of

a

period

gene

in

the

body.

6.

What

does

the

period

gene?In

other

words,How

to

realize

precise

regulation

of

circadian

rhythm

in

the

cell?OK,let’s

follow

my

steps.

7.

The

period

gene

encodes

a

protein

called

PER.

The

timeless

gene

encodes

a

protein

called

TIM.The

double-time

gene

encodes

a

protein

called

DBT.

8.

The

PER

protein

will

be

transferred

from

the

cytoplasm

to

the

nucleus

with

the

help

of

TIM

protein

at

night.The

PER

protein

will

degrade

during

the

day.

The

process

of

accumulation

and

degradation

is

about

24

hours,which

corresponds

to

people

s

day

and

night.DBT

is

to

slow

down

the

accumulation

of

PER

protein,which

controls

precise

regulation

of

circadian

rhythms.

9.

If

the

process

of

controlling

the

circadian

rhythm

is

liked

as

a

lock

and

a

key,then

open

the

lock

requires

two

keys,one

called

the

PER

protein,controlled

by

period

gene

and

the

other

called

a

TIM

protein

controlled

by

timeless

gene.

The

frequency

of

opening

is

controlled

by

the

DBT

protein

encoded

by

a

doubletime

gene.

10.

And

what

is

the

use

of

this

finding?

First,it

may

heal

some

of

the

genetic

diseases.

Second,it

cures

insomnia.

Third,it

could

reveal

the

danger

of

day

and

night.

When

we

know

the

molecular

structure

of

the

circadian

rhythm,we

will

have

a

concrete

way

to

judge

that

what

happens

to

the

human

body

when

we

stay

up

late.

11.

Nowadays,most

students

have

become

accustomed

to

sleep

very

late.

This

is

very

bad

to

health.

Now

that

the

number

of

postgraduates

who

have

died

of

fatigue

is

drastically

increasing,we

must

let

the

body

rest

at

the

right

time.

Pay

attention

to

the

biological

clock,who

is

warning

you.To

close

my

speech,I

would

like

to

tell

one

significant

thing

to

you

that

only

with

a

healthy

body

can

we

have

better

energy

to

do

more

researches.

12.

Thank

you

for

listening.

初中英语教学研究报告 本文内容:

初中英语教学研究报告

英语教学作为一门语言学,其主要目的是培养学生的语言技能,运用语言的能力,因此其课堂教学具有不同于其他课程课堂教学的特点。我通过对新课标的学习,根据中学教材的内容编排突出了对这种能力的培养,采取了指导性的学案模式,强调师生之间、学生之间的双向运用。

英语的课堂教学应当反映这种特点,以用为主,树立一种“大英语教学观”,让英语教学走出课堂,走向社会。

首先是教师观念的转变。英语教师要转变的第一个观念是:英语教学不是语言知识的教学而是言语技能的教学。过去,由于考试指挥棒的影响,英语教师过分强调英语知识的教学,结果培养了一批“哑巴英语”“聋子英语”。这次中学英语教材的改革为教师观念的转变奠定了基础。然而传统考试的“余威”仍在,考试依旧是教学的指挥棒。作为一名英语老师,是应该懂得如何在这两点找到一个平衡点。值得高兴的是中学英语教学大纲适时进行了调整,明确规定将降低语法试题的难度,减少知识性的客观题,重点培养学生的言语能力,在言语运用中学习语言。

教师观念转变的第二个方面是:由以本为本向以用为本转变。英语语言是一门不断发展的语言,现代科技的发展为它注入了新鲜的血液。英语教材只是学生学习英语的基础、媒介,学生要学好英语就必须融入英语的海洋,跟上英语发展的步伐。因此我也时常在教材教学的基础上随时把鲜活的英语输入教学,让学生能够感受英语,能够使用英语表达自己的思想。在平时的教学活动中,单一、呆板的教学方法容易使学生失去学习的兴趣,而且不能体现语言的生动性,而多种教学方法可以刺激学生的不同兴奋点,抑制大脑疲劳。计算机辅助教学使教学方法的运用有了广阔的天地。

无论哪种教法,其基本出发点是学生,学生是课堂的主体。课堂应当是学堂,是学生学习的天堂。课堂教学应当充分发挥学生主体的积极性。英语学习的特点决定了讨论法在英语课堂教学中的特殊意义。英语课的讨论法应具有更广泛的内容,更自由的民主气氛,不但可以讨论本课的问题,而且可以用英语发表自己的见解,而讨论课是在考验老师对整个课堂的驾权能力,在平时教学活动中,经常有学生在讨论课时不用英语,或者是说与本堂课毫无联系的话题,这需要老师时常督促。

新课程背景下,对中学英语语音教学提出了新的目标和要求,然而,事实上,语音教学的效果与我们想要达到的还有很大的距离。主要体现在:不能独立拼读识词,对于音标认不全、记不准;死记硬背单词字母的顺序,鹦鹉学舌式的语音发音方法,为了方便记忆,在单词上注释中文汉字或拼音,当众朗读有羞怯的心理等一系列因素造成大部分的学生英语拼读不过关,只有少数能顺利完成拼读。因此,初中英语教学必须重视语音教学,

学好音标是学好英语的前提条件,学好音标对未来的英语学习是一件一劳永逸的事,音标基础的好坏决定了一个人的语音、语调。我们应认真抓好音标教学,使初中生人人都能认识音标,读准音标,能够看音标读单词,拼写单词。教好音标,让学生打下良好的基础,对提高学生的听力水平无疑会起到事半功倍之效

一、认真教好音标,严格把好音标关

教师在教学中,或许是时间的限制,或许是认为音标不是教学的重点,就忽视了音标教学,学生的读音只是靠教师的领读、模仿、听来学习的。这样学生即使当时听了,会读了,也能读对,可是对新学习的内容,下课后,或时间一长,就忘了。所以学生靠领读、听、模仿是难以掌握读音的。为了让学生读音规范、正确,尤其在初一年级的英语教学中,教师在课堂上对要学习的内容进行编排,把音标教学穿插在整个英语教学中,使学生掌握音标,能通过音标学习单词,保证读音的正确性。当然也离不开课外学生自己的努力。音标教学是初中教学的一个重要内容,有了正确的读音,才能为以后的英语学习打下坚实的基础。

二、从学生的学习实际情况,由浅入深。

在完成字母教学和所有音素的基础上,在重读闭音节和重读开音节中,从5个元音字母的发音入手,引进发音教学最基础的规则。通过反复不断地比对和讲解。使学生能够熟练掌握读音规则,达到耳熟能详、见词读音的境界。我们这么做的主要目的是使学生能够掌握单词构成与单词发音的连接关系,并通过记音标来发音从而很好的记忆单词。同时,在这一阶段的教学中我们还要注意逐渐向学生介绍单词的音节和重音的基础知识。

教会学生按音节读单词音节教学虽然比较简单,但对初中学生的英语学习非常重要。一是因为词型变化的认识受音节的认识的直接关联,两者是互相联系,互相作用的。如动词、现在分词、过去式、过去分词,名词第三人称单数、名词复数,形容词、副词的比较级以及最高级的变化规则。二是因为学生对所学词汇的正确拼读和科学快捷牢固的记忆也是由音节的划分决定的,对于出现的比较长的词汇,我们教会学生正确划分单词音节,并按读音、音节组合、读音规则来记忆单词,效果特别明显。在音节教学时,我们按照先教音节类型再教音节的划分的顺序进行教学。初中英语初始阶段存在大量的单音节词,利用这些词进行音节教学有直观、明了的效果。当然,音标教学最重要的是教会学生拼读。拼读中应改变按字母排列顺序逐个字母拼读的惯例,最好领学生按音节和读音规则拼读。对于单音节词,学生容易读,也容易记住,但对那些双音节或多音节词,学生在朗读时,还是有一定的困难,这时,可以通过划分音节,把一个较长的单词划分成“小单词”,这样学生读和记就容易多了。

三、重视培养学生听力理解的技巧与良好的听的习惯

在语音教学中,提高学生的听力不是一时半会儿就能做到的。在日常教学中。,教师要用英语组织教学,要是加上必要的手势、表情、简笔画等,学生的注意力会更加集中,想办法去听懂老师的话;充分利用与教材配套的材料,如录音带、同步听力练习册及目标测试中的听力练习等,要坚持随教学进行训练。

教师还要对学生进行听力技巧训练,这是提高学生语音和听力理解水平的有效措施。要教会学生听音前注意略读捕捉信息,即要快速浏览习题,捕捉一切从题面上得到的信息,听时要边听边记,强化记忆,记录时要有重点,有技巧,听句子回答问题时要把题干、问题有机的联系在一起,听对话和短文时,要抓主旨大意,切忌偏重两个词而忽视全文。同时要帮助学生纠正不良的听力习惯。

英语学习、英语教学越来越受到人们的普遍重视。随着时代的发展和社会的进步,英语已从一种工具变成了一种思想,一种知识库。没有掌握英语犹如缺乏一种思想,缺少了一个重要的知识源泉。可以这样说,学会英语,不但多了一双眼睛,一对耳朵,和一条舌头,甚至是多了一个头脑!因为语言是人类思维的工具,认识世界的工具,掌握一种语言也即掌握了一种观察和认识世界的方法和习惯。英语教学,我们走在路上,任重而道远!
