of+名詞”意為“百分之……的……”，作主語時，后面的謂語動詞的單復(fù)數(shù)要與of

many

students

like

to

watch

sports,

game

shows

are

the

most

popular.

雖然很多學(xué)生喜歡看體育節(jié)目，但是游戲類節(jié)目是最受歡迎的。

although與though作連詞，意為“雖然，盡管”，引導(dǎo)讓步狀語從句。這兩個詞常可換用，只是

although比

though更為正式。例如:

Although/

Though

she

was

tired,

she

didn’t

stop

to

have

a

rest.

=She

was

tired,

but

she

didn’t

stop

to

have

a

rest.

盡管她累了，但她沒有停下來去休息。

【注意】在漢語中可以用“雖然……但是……”，但在英語中，although/though不能與but同時用于一個句子中，但可以轉(zhuǎn)換。類似的還有because和so，它們也不能同時用于一個句子中。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.

雖然通過上網(wǎng)或看游戲類節(jié)目來放松是好辦法，但是我們認為最好的放松方法是鍛煉。

（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是形式主語，真正的主語是后面的動詞不定式。例如:

It

is

very

useful

to

recite

English

sentences

and

passages.

背誦英語句子和短文很有用。

（2）through的用法。

through作介詞，在這里意為“以，憑借”。例如:

He

found

the

job

through

an

advertisement

in

the

newspaper.

他通過報紙上的廣告找到這份工作。
