Grammar Focus 语法精讲
Ⅰ. 名词性物主代词
形式
第一人称:mine;ours
第二人称:yours
第三人称:his;hers;its;theirs
用法
在句中可独立使用,相当于 “形容词性物主代词 + 名词”,其后不能再接名词。
如:I find a jacket. Is it yours?(yours=your jacket) 我找到了一件夹克衫。它是你的吗?
名词性物主代词在句中可作主语、表语或宾语。
作主语时,谓语动词的单复数与所指对象的单复数一致。
如:—Is this ruler yours or hers? 这是你的直尺还是她的?—It’s mine. Hers is in her bag.(hers=her ruler) 这是我的,她的 (直尺) 在她的包里。
Ⅱ. 频度副词
含义:表示次数、频率的副词称为频度副词。
用法
表示具体的频率、次数时,一次用 once,两次用 twice,三次及以上用 “基数词 + times”。
如:once/twice a week 一周一次 / 两次;three times a day 一天三次
表示不具体、不确定的频率、次数时,频度副词表示的频率从高到低的顺序为:
always>usually>often>sometimes>seldom (hardly ever)>never
频度副词在句中的位置:一般放在实义动词之前,be 动词、助动词或情态动词之后,有时为了强调,也可置于句首。
如:I am always busy with my homework. 我总是忙于我的家庭作业。
He sometimes gets up at 5:30 a.m.=Sometimes he gets up at 5:30 a.m.
他有时候在早上 5 点半起床。
常用 how often 对频度副词进行提问。
如:—How often does Lisa go to the library? 莉萨多久去一次图书馆?
—Never. 从不。
