only在句首要倒裝的情況:
Only in this way, can you learn English well.
Only after being asked three times did he come to the meeting.
如果句子為主從復合句,則主句倒裝,從句不倒裝
Only when he is seriously ill, does he ever stay in bed.
講解every,no,all,both,neither,nor:
1)不定代詞有
all , both, every, each, either, neither, more, little, few, much, many, another, other, some, any , one, no 以及some, something, anything, everything, somebody, someone, anybody, anyone, nothing , nobody, no one, none, everybody, everyone.等。
2) 不定代詞的功能與用法
a.除every 和no外不定代詞既可用作名詞,也可用作形容詞。every和no在句中只能作定語。
I have no idea about it.
b.all 都,指三者以上。
all 的主謂一致:all的單復數由它所修飾或指代的名詞的單復數決定。
All goes well.一切進展得很好。
all 通常不與可數名詞單數連用,如:不說 all the book,而說 the whole book。
但all可與表時間的可數名詞單數連用,如 all day,all night,all the year; 但習慣上不說 all hour,all century。
all還可以與一些特殊的單數名詞連用,如 all China,all the city,all my life, all the way
3)both都,指兩者。
a.both 與復數動詞連用,但 both… and…可與單數名詞連用。
b.both, all 都可作同位語,其位置在行為動詞前, be 動詞之后。如果助動詞或情態動詞后面的實義動詞省 去,則位于助動詞或情態動詞之前。
Who can speak Japanese?We both (all) can.
4)neither兩者都不
a.neither作主語時,謂語動詞用單數。
b. 作定語與單數名詞連用,但neither… nor 用作并列連詞,可與復數名詞連用。其謂語采用就近原則。
c.可用于下列句型,避免重復。
She can't sing,neither (can) he.
neither 與nor
d.如前句是否定式從句,則主句用neither,而不用 nor。
If you don't do it,neither should I.如果你不干,我也不干。
e. 如后連續有幾個否定句式,則用nor,不用neither。
He can't sing,nor dance,nor skate.
比較may和might:
1) 表示允許或請求;表示沒有把握的推測;may 放在句首,表示祝愿。
May God bless you!
He might be at home.
注意: might 表示推測時,不表示時態。只是可能性比may 小。
2) 成語: may/might as well,后面接不帶to 的不定式,意為"不妨"。
If that is the case, we may as well try.
典型例題
Peter ___come with us tonight, but he isn't very sure yet.
A. mustB. mayC. canD. will
答案B. 表可能性只能用may.此句意可從后半句推出。
