although与though作连词，意为“虽然，尽管”，引导让步状语从句。这两个词常可换用，只是

although比

though更为正式。例如:

Although/

have

a

rest.

=She

stop

to

have

a

rest.

尽管她累了，但她没有停下来去休息。

【注意】在汉语中可以用“虽然……但是……”，但在英语中，although/though不能与but同时用于一个句子中，但可以转换。类似的还有because和so，它们也不能同时用于一个句子中。6.It

is

good

to

relax

by

using

the

Internet

or

watching

game

shows,

but

we

think

the

best

way

to

relax

is

through

exercise.

虽然通过上网或看游戏类节目来放松是好办法，但是我们认为最好的放松方法是锻炼。

（1）句子中的前半句“It

is

good

to

relax

by

using

the

Internet

or

watching

game

shows…”是“It

is+

adj.

+to

do”的句型。其中，it是形式主语，真正的主语是后面的动词不定式。例如:

It

is

very

useful

to

recite

English

sentences

and

passages.

背诵英语句子和短文很有用。

（2）through的用法。

through作介词，在这里意为“以，凭借”。例如:

He

found

the

job

through

an

advertisement

in

the

newspaper.

他通过报纸上的广告找到这份工作。

one没有任何人no

one只用来指人，相当于not

even

one,

其后不能接of短语，作主语时，谓语动词用单数，可以回答who引导的特殊疑问句。例如:—Howmanypeoplearethereinthemeetingroom会议室里有几个人—None.一个人也没有。—Whoisinthelibrary谁在图书馆里？—Noone.谁都不在。（一个人也没有。）续表基础达标一、单项选择。1.—Couldyoutellmetheanswer________thequestion,Betty—Ofcourse.()BA.in
