of+名詞”意為“百分之……的……”，作主語(yǔ)時(shí)，后面的謂語(yǔ)動(dòng)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(yǔ)從句。這兩個(gè)詞?？蓳Q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(méi)有停下來(lái)去休息。

【注意】在漢語(yǔ)中可以用“雖然……但是……”，但在英語(yǔ)中，although/though不能與but同時(shí)用于一個(gè)句子中，但可以轉(zhuǎn)換。類似的還有because和so，它們也不能同時(shí)用于一個(gè)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(guò)上網(wǎng)或看游戲類節(jié)目來(lái)放松是好辦法，但是我們認(rèn)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(yǔ)，真正的主語(yǔ)是后面的動(dòng)詞不定式。例如:

It

is

very

useful

to

recite

English

sentences

and

passages.

背誦英語(yǔ)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(guò)報(bào)紙上的廣告找到這份工作。

【辨析】through,

many/how

其后不能接of短語(yǔ)，作主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞用單數(shù)，可以回答who引導(dǎo)的特殊疑問(wèn)句。例如:—Howmanypeoplearethereinthemeetingroom會(huì)議室里有幾個(gè)人—None.一個(gè)人也沒(méi)有。—Whoisinthelibrary誰(shuí)在圖書(shū)館里？—Noone.誰(shuí)都不在。（一個(gè)人也沒(méi)有。）續(xù)表基礎(chǔ)達(dá)標(biāo)一、單項(xiàng)選擇。1.—Couldyoutellmetheanswer________thequestion,Betty—Ofcourse.()BA.in
