E.What about you?
If we have it today,half the class won’t come.如果我们今天开
(聚会)的话,一半的学生不会来。
剖析 (1)“half+the+n.”中的half为形容词,意为“一半的,半个的”。
如:
Half the guests are women.一半的客人是女士。
(2)“half of+代词/the+n.”中的half为名词,意为“一半,半个”。该短
语在句中做主语时,谓语动词与half of后面的名词的数保持一致,即
当代词或名词为单数时,谓语动词用第三人称单数形式;当代词或
名词为复数时,谓语动词用复数形式。如:
Half of the students are playing soccer on the playground.一半的学
生正在操场上踢足球。
Half of the cheese is in the refrigerator.
一半的奶酪在冰箱里。
拓展 half表示“半数”,all表示“全部”,none表示“没有”。
