All of the crew were saved.
None of my friends ever come to see me.
Half of the building was damaged in the explosion.
crew没有用复数,但用了were,难道是根据all来判断? 这样的话第二句是none,为什么没有用三单的comes??
而第三句意思应该是成群建筑物的一半吧,为什么不是复数呢?

【答】“All of + 表示人的词语”时,表示复数概念,所以All of the crew后接 were。
“None of + 复数名词”作主语时,谓语动词可以用单数(较正式)或复数(非正式);“None of +不可数名词”作主语时,谓语动词只能用单数。 所以第二句用 come 或者comes都可以。
“half of+名词或代词”作主语时,谓语动词应该与其中的名词或代词的数保持一致。
在 Half of the building was damaged in the explosion 这个句子中,名词 building 是单数,所以谓语动词用 was damaged。
