7.部分否定和全部否定
部分否定由all(三者或三者以上),both(两者)
every(每一个) 与not 构成,即not all/both/every=all/both/every...not...
但前者比后者更直截了当,意为“并非……都”。

Both of the books are not
useful.
Not both of the books are
useful.
并非这两本书都有用。
完全否定由代词none of...(三者以上),neither
of...(两者),no one(nobody)...来表示。
None of the answers is/are
right.
没有一个答案正确。
Neither of the books is useful.
没有一本书有用。
