（79met）. if you don't know the word, why don't you______in the dictionary.
（a）look at it （b）look after it
（c）look up it （d）look it up
析：答案为d。其意指“查（字典等）”，a意为“看”，b 意为“照顾”均不符题意，故排除。由动词加 副词构成的短语，其宾语是名词时，宾语可放在整个短语后面，也可插在动词与副词之间，但宾语是代词时， 代词宾语只能插在动词与副词之间。

二、虚拟语气省略if时的词序
（95上海）.______ for the free tickets, i would not havegone to the films so often.
（a）if it is not
（b）were it not
（c）had it not been
（d）if they were not
析：答案为c。这是一个与过去相反的虚拟条件从句的省略形式，当从句中的if省略时，从句要用倒装句。 这类倒装句只需将助动词、情态动词或系动词提至主语前即可。常见句式更换如下：
a.与现在相反：if i were you (=were i you) , i would go
──with him.
b.与过去相反：if i had had time then (=had i had time
──then), i would have gone with you.
c.与将来相反：if i were to visit/should visit/visited the great wall tomorrow, (=were i to /should i visit the great
── ───wall tomorrow), i would take my son with me.
注意：在否定句中not不可提至主语前，如：
（误）weren't i here now, i would be in the bus.
────
（正）were i not here now, i would be in the bus.
──
试题选练：（94上海）.______ it rain tomorrow, we would have to put off the visit to the y angpu bridge.

────
（c）would （d）will
_______ your letter, i would have written back two daysago.
（a）if i received
（b）should ireceive
（c）had i received
────────
（d）if i could have received
三、否定词放在句首时的词序
（91met）"do you know jim quarrelled with his brother@" "i don't know,_____
（a）nor don't i care
（b）nor do i care
（c）i don't care neither
（d）i don't care also
析：答案为b。a项多了not，c项、d项分别要改neither、 also 为either。否定词作状语放在句首时要用 倒装句，倒装句只需将情态动词、助动词、系动词be提至主语首即可（见例2）。 实意动词的倒装要在主语前 面加助动词 do，does，did等，此时谓语动词要用动词原形（见例1）。常见的否定词或结构有：neither/nor /never/hardly/ little/seldom/ scarcely/ barely/ not until/no sooner than/hardly when/not only…b ut also/at no time/not once/by no means
例：1.little did einstein care for money.
──
2.by no means( never/at no time) will china besuperpowers.
