1. A.
   still teaches
2. B.
   is still teaching
3. C.
   still taught
4. D.
   will still teach

Answer 1

B
分析：由She has taught for nearly thirty years和now可以知道是說(shuō)“她現(xiàn)在仍然在教書”的意思，teach是可以延續(xù)的動(dòng)作，所以用is still teaching．(延伸)still作“仍然”解釋時(shí)，動(dòng)詞用一般時(shí)還是進(jìn)行時(shí)取決于兩點(diǎn)：1．是延續(xù)性動(dòng)詞還是短暫性動(dòng)詞，是延續(xù)性動(dòng)詞用進(jìn)行時(shí)，是短暫性動(dòng)詞用一般時(shí)。2．所說(shuō)的事情是強(qiáng)調(diào)處于進(jìn)行過(guò)程中還是指經(jīng)常性的情況，前者用進(jìn)行時(shí)，后者用一般時(shí)，如：I still use the watch he gave me．(我仍然在使用他給我的那塊表)這里的“使用”是指現(xiàn)階段的“使用”，所以用一般時(shí)。(延伸)still作“仍然”解釋時(shí)，注意其位置：He still looks very young．(放在實(shí)意動(dòng)詞的前面)He is still very young．(放在is，am，are，was，were的后面)I still don't understand what you mean．(放在否定謂語(yǔ)的前面)(延伸)still修飾形容詞或副詞的比較級(jí)時(shí)不解釋為“仍然”，要解釋為“更”“益發(fā)”，still作形容詞時(shí)要解釋為“靜止的”“不動(dòng)的”“寂靜的”，如：Please stand still while I take your picture．(stand still“站著不動(dòng)”，still stand“仍然站著”)The town is still very quiet．
