2. 用含否定意义的词(如never, nothing, nobody, none, neither,
little, few等)。
(1)always
/ ever →never, and →or。如:
He was
always late for school last term.
→He was never late for school last
term.
(2)too→not…either,
already→not…yet。如:
He goes
to school by bike, too.
→He doesn’t go to school by bike, either.
(3)all→none, both→neither,
both…and →neither…nor,此时,谓语动词仍用肯定形式,但当neither作主语,谓语动词用单数形式;“neither …nor…”连接两个主语时,谓语动词应和靠近它的主语保持一致。如:
He knows
all of the workers here.
→He knows none of the workers here.
Both of
the twins are from England.
→Neither of the twins is from
England.
