came
back
with
a
box
full
of
cards.
All

was

and
asked,
“Oh,
what
are
these?”
“Mum,”
Tom
answered,
“I
bought
the
cards
and
wrote
all
of
them
a
few
days

Hearing
this,
his
mother
was
very
moved
and

dear”.

句群翻译。
上周我爸爸给我买了一台笔记本电脑(laptop)作为生日礼物。它是Founder
1007。
它重1.8千克,比我的旧电脑轻得多。它不是很大,14英寸。它比旧电脑更美观,但是它更贵,价格是4,800元。
在我的日常生活中,电脑发挥着重要作用。我可以用它来做很多事情,比如查找信息,储存信息,和朋友聊天等。我很少用电脑玩游戏。如果我花大量的时间打电脑游戏,我将得不到充分的休息。而且,对眼睛有害。
我认为,如果我们合理地使用电脑,它们会对我们非常有帮助。

【范文赏析】
  
Last
week,
my
father
bought
me
a
new
laptop
as
my
birthday
gift.
It
is
Founder
1007.
It’s
much
lighter
than
my
old
computer,
only
1.8
kilograms
heavy.
It’s
not
big,
14
inches
in
size.
It’s
more
beautiful
than
the
old
one,
but
it’s
more
expensive.
It

My
computer
plays
an
important
role
in
my
daily
life.
I
can
use
it
to
do
many
things,
like
looking
up
information,
storing
information,
chatting
with
friends
and
so
on.
I
seldom
use
it
for
playing
computer
games.
If
I
spend
much
time
playing
games,
I
will
not
have
enough
time
to
rest.
In
addition,
it’s
bad
my
eyes.
In
my
opinion,
computers
are
helpful
for
us
if
we
use
them
in
a
proper
way.
