Answer 1

C
试题分析：never从不，否定含义，放在句首，句中的主谓要用倒装结构。根据句意用现在完成时。句意：我教学超过20多年，但我从没有遇到过和Lily一样聪明的女孩。
考点：倒装。
点评：掌握英语中否定词放在句首，句子结构要主谓倒装。hardly, in no way, little, scarcely, seldom, never, no more, no longer, not, not only, no sooner, not only … (but also),not until… 等具有否定意义的词或词组位于句首，句子用部分倒装。 部分倒装：指将谓语的一部分如助动词或情态动词倒装至主语之前,而谓语动词无变化。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。eg：
No sooner had I got home then it began to rain. 我刚到家就下起了雨。
Seldom do I go to work by bus. 我很少乘公共汽车上班。
Not until twelve o'clock did she go to bed last night . 她昨晚十二点才上床睡觉。
