低保申请怎么写-端午节手抄报花边
Hello，everyone
Good morning！My name
is Xiao Weihong,I’m from
Sichuan today,my
topic is Fog and
is my name,and this is my
student number.
From this you can know that my
topic is about 5
parts,and now,we look at the
first
long ago,we climb with our hands,as
time goes by,We are
walking the environment
turns bad,we live in a
world which is full of
recent years, air pollution
has already become
one of the biggest environmental
problems in
China. Thick haze has blown off the coastal
,what is haze?It’s a combination of little
drops of
water and tiny particles. For better
understanding of this
,we should know another
means
particulate also means a small
discrete[dɪ'skrit](离散的) mass of solid or
liquid
,we can easily know what is means
particles can be drawn into lung[lʌŋ], which
diameter is
less than 2.5 often pay our
attention to PM2.5，
because the number of 2.5
is very important ,if the
diameter of particle
is bigger than 2.5 micron,it will be
stopped
by our nose and will not go into our lung. But if
the size of particle is less than 2.5
harms us
most.
So, wether['wɛðɚ] our
weather['wɛðɚ] is good is
determined by the
number of at this picture,if
the number of
PM2.5 of per unit volume is less than 50,we
say the air quality is the number is between
50 to
100,we say the air quality is if the
number is
between 151 to 200,we call it if
the number
is above 300,we think it we
know,many places
of China is even above ,it’s
very dangerous.
Now,let’s look a historical
smog!Let’s
know about ,we watch a short
video.(I don’t know
wether the computer can
paly it) Ok,from this short video
we can see a
black world full of ,what happened
in
London?In 1952, London smog happened,and it lead
to
12000 people died directly or 1954 ,London
launched a special act of 4 years
later,smog happened again,and 1200 people
after 1965,the toxic smoke was 1968,Britain
enacted the Clean Air until 1980, the fog day
has
been reduced to five days one took about
30 years
to solve the ,from this accident,we
know that
once the fog happened, it
will be hard to solve it.
How about our
situation?First,Let’s look some
’re two
contrast upper left
corner is a picture of
beautiful scenery,it’s clear,but the
one at
the lower left corner looks the top right
one
is the map of our country which looks pretty,but
from
this one we can see nothing except about
this
one?Oh,it’s a man who wears a
respirator['rɛspəretɚ] is
riding a bike in the
endless again,this picture
tells us a man is
riding a bike in the ’s dangerous
because it’s
hard to see far. The last one,it looks beautiful
in some like mushrooms,the more beautiful
the more toxic it fact,it’s very terrible.
So,what
situation
caused
?These
our
several
country to be
are
this
we reasons
,burning of fossil
fuels in we
know,the number of cars in our
country is increased
,the demand of fossil
fuels is increased
fast,too .Second,in our
country the power plants still rely
on fossil
fuels. It contributes to air pollution
,various industrial processes are existed
emissions of waste polluted the air.
Therefore,it’s time to take some
measures to change
the situation .So, what
should our government do?
Firstly,our
government should strengthen air monitor to
know the the actual ly, government
should
enact more strict laws and regulations in order to
reduce the sources of y,government
should
regulate people 's daily action and the industrial
,our country should help develop green
and
energy-saving do these can our country
become
beautiful an individual,what should we
do to
reduce the harm of haze?First,if conditions
permit,we can wear a respirator which can help
us
perhaps not ,if we go out ,we should try to
take public ,hybrid['haɪbrɪd] cars
should
be regarded. Four,clean energy should be
promoted in our daily the last,the public
supervision
is important. Not only the role of
government, but must
have the personal do
this can we have a better
let’s do something
from now on.

before,the PM2.5 will go into our lung
though our
respiratory['rɛspərətɔri] -term
effects can
