None可指人也可指物,作主语时,如和of连用指不可数名词时,谓语动词要用单数形式;指可数名词时,谓语动词用单、复数均可.如
Noneofthemhas/haveseenmebefore.
Noneofthismoneybelongstome.
注意:
1)none可与of连用表示范围.
2)none可用来回答Howmany/much…?的特殊疑问句如:
—Howmanybirdsarethereinthetree?
—None.
—Whatisinthebox?
—Nothing.
—Whoisintheclassroom?
—Noone/Nobody.
3)none可用来回答“any+名词”构成的一般疑问句如:
—Isthereanybreadleft?
—No,noneatall.
—Isthereanythinginthesky?
—No,nothing.
4)none可用来指代前面提到过的人或物;
Wehadthreecatsonce—noneofthemisalivenow.
我还想问一下,如果是可数名词,什么时候用单数,什么时候用复数?有没有什么条件?
None可指人也可指物,作主语时,如和of连用指不可数名词时,谓语动词要用单数形式;《指可数名词时,谓语动词用单、复数均可。》如Noneofthemhas/haveseenmebefore.(可数名词,故单复都可用)Noneofthismoneybelongstome.(不可数名词,故只能用单数)
