下面这篇两个题目都适用。

希望您满意！

All of us know that exercise is good for our health. Regular exercise can help protect you fro-

m heart disease and stroke, high blood pressure , obesity, back pain, osteoporosis and can improve

your mood and help you to better manage stress. Exercise may power up the brain besides stveng-

thening the heart and lungs, bones and muscles . A succession of scientific studies of animals imp-

lies that physical activity has a positive effect on mental functioning.

Of course , everything has its contradictory. However, few are aware of the fact that one of

the result of doing exercise is iron loss. Exercise can result in iron loss for the following reasons .

One is that some iron is lost in sweat produced in the exercise . Another reason is blood leaking.

Besides ,exercise may reflect on bruise.

In a word, exercise may do us good but also harm. So, moderate exercise is necessary, but

you should pay attention to some problems when you dou some exercise .

Certainly, in my opinion , doing more exercise may have unexpected benefits, as long as you have health-conscious.

Dear
Jack,
Thank
you
for
your
pervious
email
and
the
photos.
It's
nice
to
hear
from
you.
However
I
surprised
that
in
the
photo
you
were
smoking
with
others.
It's
not
really
my
business
but
I
have
to
say
smoking
is
not
good
for
your
health.
There
are
some
articles
about
how
to
quite
smoking
which
I
attached
in
the
attachment
for
your
reference.
You
can
have
a
look
when
you
decide
to
stop
smoking.
Regards,
XXXX
谢谢
