美在不期而遇-我眼中的缤纷世界作文
有关科学技术的英语范文关于科技发展的英语作文
Nowadays, technology is everywhere
around us. The
development of
technology has a significant affact toward
the society. Several technologies that
we usually use are
the inter, puter,
and cellphone. These new technologies
make our life much easier and better.
First, the
development of puter changes our life.
Decades ago, people needed to do lots
of plex calculation
on hand because
they did not have puter, and more obvious,
they did not have the software for
calculation. As the
result of that,
people spent hours on the equations that a
puter can solve in just a minute. Since
the development of
puter, people are
able to use some kind of software to pute
lots of plex functions and mathematical
calculation.
Computer bees the most
helpful equipment for the sciencists
because they can use their time more
efficiently.
In
conclusion, I believe the development of
technology
brings significant impact to
our life. It is very helpful
to us and
I believe technology will keep improving in
future.
The development of
science and technology makes our life
more fortable and convenient. However,
scientists have
created many problems,
which are not easy to be resolved,
such
as air pollution, the deterioration of environment
and
the scarcity of natural resources,
to which we must some
solutions.
Modern science and
technology render people many
advantages. Modern telemunication
shortens the distance
between people
and makes munication much easier. Inter is
widely used now not only for collection
of abundant
information but also for
correspondence. Email, the most
effective munication device now, is
being very popular.
Besides, telephone
and mobile phone make contact more
convenient than before.
Modern transportation, such as
airplanes and high-speed
trains make
our journey smooth and fast. With the help of
modern transportation, people can go
everywhere they prefer
to. The journey
to outer space and other plas is not a
dream any more. Rockets and
space shuttles can help us
realize the
dream of space travel.
Modern medicine prolongs peoples life and relieves
patients of sufferings from many
diseases. Cancer and AIDS
are fatal to
peoples health. Thanks to the endeavors
scientists have made, these diseases
bee treatable.
However, the process of scientific development
also
arouses many sever problems to our
human beings. Inter,
though widely used
in modern munication, is easy to be
destroyed by puter virus. Outer space
exploration has
produced much waste in
the space. A tiny metal, a screw,
for
example can destroy a flying man-made sa ___ite.
Industrialization is making natural
resources bee scarce.
Confronted with these problems, scientists are
seeking
prompt and feasible solutions.
The development of science
and
technology bring about both positive and negative
effects to us. We must eliminate the
positive effects to
the least extent.

(Modern Technology Makes Life More
Convenient)
Modern technology
makes life more convenient; tools are
the milestores of the technology as
well as human being

s
progress.
Men used to cut trees with hand saw. But now, by
using
electronic saw they can cut down
a tree in only a few
minutes. Another
example is more vivid: You have something
urgent which has to be informed to your
friend whose house
is two
hour
’
s ride away. You probably want to make a phone
call. But no telephone
is installed in your friend
’
s
home. What could you do? Nowadays, with
modern technology
advanting, using
inter is popular with us. Some years ago,
people had to get what they wanted
through looking into a
lot of
information; at last people could bee tired and
spent too much time. Now, if you use
Inter, all bees a
piece of cake. Only by clucking, you
will gain what you
expect.
We all hope that modern technology
will reach a higher
level, because
modern technology makes life more convenient
indeed.

people are able to use some kind of

bees the most helpful equipment for
the
sciencists because they can use their time more

Also
,
inter is another useful tool for us today. The
development of inter brings a great
impact toward the
society. Instead of going to library
and fliping all the
books to figure out
some information
,
we can just simply
use a mouse and click on the website to
do research. The
inter leads us to a
place where we can find unlimited
information and resources. It makes our
life much easier
and better.
The last technology
is cellphone. Nowadays
,
many people
have a cellphone. But it just appears
on the market for
about 10 years. It is
very convenience to the users because
we can talk to anyone we want with a
phone as small as a
wallet.
Also
,
we can municate with others by making a
phone call instead of sending
letters. It is very fast and
useful way
to municate.
In
conclusion
,
I believe the development of technology
brings
significant impact to our life. It is very helpful
to us and I believe technology will
keep improving in
future.

As is
vividly depicted by the picture above, a traveler
happily starts his journey by high-
speed railway from
Guangzhou to Wuhan.
In the year of xx, Wuhan-Guangzhou
high-speed railway went into operation,
reducing travelling
time from 12 hours
to 3 hours, bringing much convenience to
the transportation between the two
cities
①
. No wonder the
caption in the picture says
“
with the Wu-Guang high-speed
railway, cities far away is just like a
place nearby
”。
Science and technology are the
primary productive forces
②
and have been playing a key role in the national economy
development. On the one hand,
progress in science and
technology has
promoted economic and social progress
greatly. Take the high-speed railway as
an example.
Firstly, the railway bees a
new engine
③
of booming of
regional economic. Secondly, the
railway helps to attract a
lot of
tourists, so that tourism in these cities
flourishes. Last but not the least, the
load of the
existing transportation
work can be released to a great
extent.
On the other hand, with the development of science
and technology, such as the operation
of high-speed
transportation, video phone, webcam
meeting, the world has
bee smaller and
smaller
。
It has long been a tradition for Chinese
government to
attach great importance
to the advances

in science and
technology. Science and technology has
suessfully shaped an
entirely new image
of China on global stage via the two
grand world events, xx Olympic Games
and xx Shanghai World
Expo. It is
strongly advised that young people should
devote themselves into the study of

precipitable water vapor level of 0.001 mm. The
downward spikes
in the graph correspond to frequencies at
which microwaves are absorbed more

Microwaves are a form of electromagic radiation

millimeter, or equivalently, with frequencies
between 300 MHz (0.3 GHz) and 300

and various sources use different
boundaries. In all cases,
microwave
includes the entire SHF band (3 to 30 GHz, or 10

engineering often restricting
the range
between 1 and 100 GHz (300 and 3 mm).
The prefix

that microwaves are
