2013年英语六级改错指导：特殊句型

　　例1：Animation(动画)means making things which are lifeless come

　　Alive and move. Since earliest times, people have always been fascinated by

　　movement. But not until this century we managed to capture movement, _______

　　to record it, and in the case of animation, to reinterpret it and recreate it.

　　解析：状语not until…提前，后面的主句主谓倒装，根据上下文和谓语managed可推断该句应为完成时。故在we 前加have。

　　拓展：部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前。如果句中的谓语没有助动词或情态动词，则需添加助动词 do, does 或 did ，并将其置于主语之前。

　　句首为否定或半否定的词语，如 no, not, never, seldom, little, hardly, at no time, in no way, not until... 等。

　　EX1. Never have I seen such a performance.

　　EX2. Nowhere will you find the answer to this question.

　　EX3. Not until the child fell asleep did the mother leave the room.

　　当 Not until 引出主从复合句，主句倒装，从句不倒装。

　　以否定副词开头并加状语的句子要求部分倒装。这些否定副词有barely, hardly, little, seldom, , never, no sooner…… than, rarely, no more, nor nearly, Not only...but also, Hardly/ Scarcely ...when, No sooner... than等以及only

　　EX1. Not only did he refuse the gift, he also severely criticized the sender.

　　EX2. Hardly had she gone out when a student came to visit her.

　　EX3. No sooner had she gone out than a student came to visit her.

　　例2：It is Western health-care system which are spending huge sums of ______

　　money on the surgical treatment of the disease.

　　解析：这个是It is …that…强调句。无论后面的从句缺少什么成分，都只能用that来引导并且不能省略(如果强调部分是人时，可以用who)。故将which改为that。

　　例3：The boy wanted to play football in the street, but his mother told him not. ________

　　解析：这个是省略句，完整为The boy wanted to play football in the street, but his mother told him not to play football in the street。动词不定式的省略：在动词不定式结构中，为了避免重复，常常省略不定式结构中的动词原形，只保留to。所以应该在not后加个to。
