① 英語語法的非謂語動詞
您好!很高興為您解答!
由於您沒有具體指出非謂語動詞的哪種用法,以下是非謂語動詞用法小結:
1.不帶to的不定式
1)在表示生理感覺的動詞後的不定式不帶to。這類詞有:
feel 覺得 observe 注意到,看到 overhear聽到
watch注視 listen to聽 perceive察覺,感知
notice注意 see看見 look at看 hear聽
2)另一類是某些使役動詞,如make, let,have等。
(注):
①上述感覺動詞與使役動詞轉換為被動結構時.其後的不定式一般需帶to,如:
He was seen to come.
The boy was made to go to bed early.
②在動詞find與help之後,不定式可帶to亦可不帶to,如:
He was surprised to find the sheep (to) break fence at this season.他發現羊在此季節越出柵欄,感到驚訝。
3)在do nothing/anything/everything but(except)結構中。例如:
Last night I did nothing but watch TV.昨天晚上,我除了看電視別的什麼也沒有干。
但是,如果謂語動詞不是「do nothing,anything,everything」,那麼but(except)所跟的不定式則仍須帶。
The doctor told him nothing but to stop smoking.醫生除了讓他戒煙,其它什麼都沒有說。
There was nothing for them to do but to remain silent.除了保持沉默以外,他們沒有別有別的辦法。
2.with 的復合結構(作狀語或作定語)
with+ n.+ to do/ to be done (動詞不定式的動作還未進行)
with+ n.+ doing/ being done (動詞不定式的動作正在進行)
with+ n.+ done (動詞不定式的動作已經完成或指n. 所處的狀態)
1). With so many problems to settle, the newly-elected president is having a hard year.
2). He was lying in bed, with his eyes fixed on the ceiling
3.不定式和分詞作狀語的區別
(1)現在分詞與過去分詞作狀語的區別。
現在分詞做狀語與過去分詞做狀語的最主要區別在於兩者與所修飾的主語的主動與被動關系的區別。
1)現在分詞作狀語時,現在分詞的動作就是句子主語的動作,它們之間的關系是主動關系。
3). With the temple being repaired, we can』t visited it.
2)過去分詞作狀語時,過去分詞表示的動作是句子主語承受的動作,它們之間的關系是被動關系。
(2)動詞不定式和分詞作狀語的區別
1)分詞作狀語一般表示伴隨,而不定式常常表示目的。
They stood by the roadside talking about the plan.他們站在路邊談論著這個計劃。(伴隨)
They stood by the roadside to talk about the plan.他們站在路邊為的是談論這個計劃。(目的)
2)分詞作狀語放在句子開頭,除表示原因之外有時表示時間或條件。動詞不定式作狀語時,除了表示目的以外,還表示結果或原因。
Reading attentively,he forgot the time for lunch.由於在專心讀書,他忘了吃午飯的時間。(原因)

反意疑問句用來表示提問者有一定的主見,但是沒有把握,希望對方來證實。

對反意疑問句回答,不管問題的提法如何,事實是肯定的就用肯定回答,否定的就要用否定的回答。
He isn』t going to the meeting, is he?
Yes, he is. 不,他要去的
No, he isn』t. 對,他不去
反意疑問句通常由一個陳述句和一個疑問句組成。當陳述句為肯定時,疑問句為否定;當陳述句為否定時,疑問句為肯定。但是以下幾個要注意:
1. 陳述部分主語 I, 疑問部分要用aren』t I
I am as tall as your sister, aren』t I ?

③ 初三英語復習,非謂語動詞!大師級回答!
B (prefer doing sth. to doing sth. else 喜歡做某事而不是別的事)
C (stop sb. from doing sth. 阻止某人做某事;throw litter about 「亂丟垃圾」)
C (have a picture discussed 讓人討論一幅畫)【這個句子後面的were very important 是多餘的。估計是打錯字了】
A (excited 「興奮的」,用來描述人)
A (sing是感官動詞,後接賓語+不帶to的賓補)
D (第一個空 have sb. do sth.,使役動詞+賓語+不帶to的賓補;第二個空 have the trees watered,意思是「請人給樹澆水」,樹是被澆,所以用過去分詞。)
④ 初三英語問題非謂語動詞

⑤ 英語語法-關於非謂語動詞
完整的一抄個句子必須有襲謂語動詞。但是分句就不一定了。 I like him. HelloKitty is cute. If time permitting, I will go shopping. 動詞後面可以跟副詞和名詞,只是意義不同。
⑥ 初中英語語法非謂語動詞
實意動詞除作謂語外,還有不能單獨作謂語的形式,即非謂語動詞。非謂語動詞包括:不定式,動名詞,分詞(現在分詞和過去分詞)
動名詞
動名詞是動詞-ing形式的一種,特點是只能作句子的主語和賓語,但是沒有單復數形式之分,在此不再贅述。
動詞不定式
動詞不定式在句子中可以充當主語,賓語(表語),定語,狀語,和賓語補足語。
不定式充當主語常用形式主語it作形式主語,例如:
It
is
very
hard
to
finish
the
work
in
ten
minutes.
It
means
failure
to
lose
your
heart.
不定式充當賓語一般表示短暫的或尚未發生的行為。例如:
I
like
drinking
tea
in
usual,but
today
I
like
to
have
a
little
wine.
After
walking
for
a
whole
day,
Tom
only
wanted
to
sleep.
注意當不定式作賓語時如果有賓語補足語,則用it作形式賓語,例:Marx
found
it
important
to
study
the
situation
in
Russia.
不定式作定語一般要後置,例如:①Allen
is
the
best
man
to
take
this
job.②He
found
a
good
house
to
live
in.
不定式作賓語補足語:在復合賓語中,動詞不定式可充當賓語補足語,常見該類動詞有:
want,
wish,
ask,
tell,
order,
beg,
permit,
help,
advise,
persuade,
allow,
prepare,
cause,
force,
call
on,
wait
for,
invite.
有些動詞如make,
let,
see,
watch,
hear,
feel,
have等與不帶有to的不定式連用,但改為被動語態時,不定式要to,
如:
I
saw
him
cross
the
road.
He
was
seen
to
cross
the
road.
此外,介詞有時也與這種復合賓語連用,如:With
a
lot
of
work
to
do,
he
didn』t
go
to
the
cinema.
不定式作狀語通常有以下幾種用法:
表目的:He
worked
day
and
night
to
get
the
money.
注意不定式放句首時,邏輯主語與句子主語要一致:
表結果:He
arrived
late
to
find
the
train
gone.常用only放在不定式前表示強調:I
visited
him
only
to
find
him
out.
表原因:They
were
very
sad
to
hear
the
news.
表程度:It』s
too
dark
for
us
to
see
anything.
作獨立成分:To
tell
you
the
truth,
I
don』t
like
the
way
he
talked.
注意①不定式的省略:保留to省略do動詞。If
you
don』t
want
to
do
it,
you
don』t
need
to.②不定式的並列:第二個不定式可省略to。He
wished
to
study
medicine
and
become
a
doctor
分詞
分詞在句子中可以充當定語,補語和狀語。注意在區分使用現在還是過去分詞時,最簡潔有效的方法是看分詞與被修飾詞的關系。如果分詞的動作是被修飾詞發出的,就使用現在分詞;如果分詞的動作是被修飾詞承受的,就使用過去分詞。例如:
作狀語:
①Listening
to
the
music,Tom
cleaned
the
house.(聽音樂的動作也是由Tom發出的)
②Blamed
by
his
father,
the
boy
left
home
without
words.(the
boy是責罵的承受者)
注意當動作由被修飾者發出但是分詞的動作與主句的動作有明顯時間差時,要使用現在分詞的完成時,例如:
Having
finished
all
the
homework,
Mary
helped
her
mother
with
the
housework.做完功課之後,瑪麗幫媽媽做家務。
作定語和賓語補足語:
The
interesting
boy
makes
people
interested.這個有趣的小男孩讓人們很感興趣。(boy是動作的發出者,所以用現在分詞修飾;people是承受者,所以用過去分詞修飾)
The
annoying
noise
made
all
students
annoyed.惱人的噪音讓學生們都很惱火。(noise是動作的發出者,所以用現在分詞修飾;students是承受者,所以用過去分詞修飾)
動詞現在分詞作賓補與不定式作賓補的區別見單詞總結。
