vocabulary简明 A need is something essential: people need food, water, and shelter. When you lack them, you're in need.
vocabulary扩展 Besides physical needs like sleep, people have lots of psychological needs: like for love and friendship. To pass an exam, you need to study. To lose weight, you need to exercise more and eat less. Drug addicts feel a physical need for their drug — so do smokers. Often, we feel we need things that we actually just want: like a new video game or car. When someone is trying hard to get something, they might say "I need it!"
柯林斯解释
Usage Note :

Need sometimes behaves like an ordinary verb, for example 'She needs to know' and 'She doesn't need to know' and sometimes like a modal, for example 'She need know', 'She needn't know', or, in more formal English, 'She need not know.' need

有时用作普通动词,例如:She needs to know (她需要知道),She doesn't need to know (她不需要知道)。有时 need 用作情态动词,例如:She need know, She needn't know 或更为正式的说法:She need not know。
