What
Do
No.5
High
School
Students
Do
in
Their
Free
Time
Last
month
we
asked
our
students
about
their
free
time
activities.
Our
questions
were
about
exercise,
use
of
the
Internet
and
watching
TV.
Here
are
the
results.
We
found
that
only
fifteen
percent
of
our
students
exercise
every
day.
Forty-five
percent
exercise
four
to
six
times
a
week.
Twenty
percent
exercise
only
one
to
three
times
a
week.
And
twenty
percent
do
not
exercise
at
all!
We
all
know
that
many
students
often
go
online,
but
we
were
surprised
that
ninety
percent
of
them
use
the
Internet
every
day.
The
other
then
percent
use
it
at
least
three
or
four
times
a
week.
Most
students
use
it
for
fun
and
not
for
homework.
The
answers
to
our
questions
about
watching
television
were
also
interesting.
Only
two
percent
of
the
students
watch
TV
one
to
three
times
a
week.
Thirteen
percent
watch
TV
four
to
six
times
a
week.
And
eighty-five
percent
watch
TV
every
day!
Although
many
students
like
to
watch
sports,
game
shows
are
the
most
popular.
It
is
good
to
relax
by
using
the
Internet
or
watching
game
shows,
but
we
think
the
best
way
to
relax
is
through
exercise.
It
is
healthy
for
the
mind
and
the
body.
Exercise
such
as
playing
sports
is
fun,
and
you
can
spend
time
with
your
friends
and
family
as
you
play
together.
And
remember,
“old
habits
die
hard”.
So
start
exercising
before
it’s
too
late!
Read
the
passage
quickly
and
find
the
answer
to
the
questions
below.
How
many
kinds
of
free
time
activities
are
mentioned
in
the

percent
名词，意为“百分之……”
e.g.
Eighty
percent
of
the
students
in
our
class
exercise
every
day.
我们班里80%的学生每天都锻
炼。
【注意】
percent做主语时，谓语动词的数要根据其后面的名词来确定。
e.g.
①
Fifty
percent
of
the
apples
are
bad.
50%的苹果都坏了。
②
Twenty
percent
of
the
meat
is
in
the
fridge.
20%的肉都在冰箱。
2.
And
twenty
percent
do
not
exercise
at

not
…
at
all
意为“一点也不”，
not应和be动词、助动词或情态连用。
e.g.
①
The
story
isn’t
interesting
at
all.
那个故事一点也没有趣。
②
They
didn’t
enjoy
the
vacation
at
all.
他们根本不喜欢那次旅行。
③
The
old
man
can’t
use
the
computer
at
all.
那位老人一点也不会使用电脑
3.
The
answers
to
our
questions
about
watching
television
were
also
interesting.
对我们提出的有关看电视的问题的答案也挺有意思。
1）句子主语为
the
answers
，故谓语用
were。
2）
表示“…的答案”要用“answer
to…”
如：①
There’s
no
easy
answer
to
this
problem.
这个问题没有简单的答案。
②
Her
answer
to
your
question
is
a
big
“NO”!
她对你所提的问题的答案是一个大大的“不”字！
3）表示“有关…的（问题）”用question
about…
如：①
He
asked
us
some
questions
about
our
daily
habits.
他问了一些有关我们日常习惯的问题。
②
Her
questions
about
you
were
not
so
friendly.
她有关你的那些问题并不那么友善。
4.Although
many
students
like
to
watch
sports,
game
shows
are
the
most
popular.
虽然很多学生喜欢看体育节目，但游戏类节目是最受欢迎的。
although
为连词，意为：“虽然，尽管”。
注意：在英语中，当表示“虽然…，但是….”这样的意思时，although和but不能在同一个句子中使用。也就是说，在一个句子中，有although就没有but
，反之亦然。如：
Although
the
car
is
old
,
it
still
runs
well.
=The
car
is
old
,
but
it
still
runs
well.
这辆小车旧了，但是依然跑得不错。
5.
Exercise
such
as
playing
sports
is
fun…
such
as
意为“像……这样”，表示列举。
结构常为：名词+
such
as
+
例子
e.g.
She
likes
animas
such
as
rabbits
and
birds.
她喜欢像兔子、小鸟这样的小动物。
注意：其后面不可列举出所有的事物。如：
我了解四种语言，例如英语、汉语。
I
know
four
language,
such
as,
English
and
Chinese.
(√)
I
know
four
language,
such
as,
English,
French,
Japanese
and
Chinese.
(×)
6.
So
start
exercising
before
it’s
too
late!
所以赶紧锻炼起来，不要等到来不及了。
It’s
too
late
字面意思为“为时太晚，来不及了”
是英语的一个常用表达。如：
Now
you
know
you
are
wrong
,
but
it’s
too
late.
你现在知道错了，已经太晚了。
句中，
It’s
too
late
与before共同组成从句，表示“不要等到为时已晚；不要等到来不及的时候；趁还来的及”。如：
You
should
work
harder
before
it’s
too
late
to
catch
up.
你现在用功还赶得上。
