Question

both 和 all的区别

Answer 1

相同点:都可以作形容词、代词，如(都是词霸上的例子)
1. Both guests have arrived. Both the books are torn. Both her fingers are broken.
All the windows are open. Deal all the cards.
注意:both和all作形容词嫌察滑修饰名词，在有冠词的情况下放在冠词前，这一点和其他形容词不同。例如，all the world 和 the whole world
2. Both were candidates. We are both candidates. Both of us are candidates.
All that I have is yours. We are all Chinese. All of us are sick.
3. 与否定词“not”连用时只表示部分没枯否定，而且不要被“not”灵活的位置迷惑，芹腊应理解为“不是所有的…都…”

不同点:both可作连词，all可作副词，如
1. both men and women; an attorney well regarded for both intelligence and honesty.
2. a room painted all white; directions that were all wrong. all能修饰形容词
2. 数量上:both固定是“两、双”，而all表示“三个或三个以上”

Answer 2

all , both, 表示“都”，“全部”。
(1) both指两个人或物，而all指三个以上的人或物，在句中都可作主语、宾语、表语、同位语或定语。
Both of us want to go. 我们两人都想去。
All of us should work hard.我们都应努力工作。

(2) both和all都可直接修饰名词；名词前如有限定词时，其前只能用both of或all of。
Both brothers are clever. 兄弟俩都聪明。
Both of the books are useful.两本书都有用。

(3) both和all在句中的位置是位于be动词之后，行为动词之前，如有情态动谨消御词或助动词，则位于情态动词或助动词与主动词之间。
We are all here. 我们都来了。
[特别提醒]

(1) both的反义词是neither, all的反义词是none。

Both of us are not doctors. 我们俩并非都是医生。 (部分否定)

Neither of us is a doctor. 我们俩都不是医生。(全部否桥腔定祥岩)

All of the books are not helpful. 并非所有这些书都对人有帮助。(部分否定)
