4.I’ve
never
been
camping.
我从未野营过。
此句为现在完成进行时。这一时态的结构为“have
been
+
现在分词”，表示从过去某一时刻延续至今的动作。在本句中，说话人使用这一时态来强调自己至今从未有过野营的经历，欠缺这方面的经验。

ever

wonder
how
much
more
computer
will
be
able
to
do
in
the

1)wonder
表示“
(对某事)感到疑惑；想要
知道；想弄明白；琢磨”，后面常接由what,
how,
who
或者if/whether引导的宾语从句。
e.g.
I
wonder
how
they’re
getting
on.
我想知道他们现在过得怎样。
Knowledge
points
I
just
wonder
if
they’ve
arrived
safely.

2)
此句从句部分的原始结构是:
How
much
more
will
computers
be
able
to
do
in
the
future?
是对陈述句Computers
will
be
able
to
do
(much)
more
in
the
future.(电脑将来能够做更多的事情。)的提问。由于充当了宾语从句,
疑问结构改成了陈述结构:
Knowledge
points
how
much
more
computers
will
be
able
to
do
in
the
future,
即:
将助动词还原到陈述句的位置。
e.g.
I
don’t
know
when
he
will
come.
我不知道他什么时候来。
I
don’t
know
where
he
lives.
我不知道他住在哪里。

-able是一个典型的形容词后缀,
可加在动词之后,
表示“可…...的;

令人愉快的)
便是一例,
再如:drinkable(可饮用的),
washable(可洗的),
readable(可读的),
usable(可用的;
可使用的)等等。
