149 表示无义务的各种形式
| |
说话人的权威 |
外界的权威 |
| 将来时 |
need not |
shan't/won't need to
shn't/won't have to |
| 现在时 |
need not |
don't/doesn't need to
don't/doesn't have to
haven't/hasn't got to |
过去时
（参见第150节B） |
didn't need to
didn't have to
hadn't got to |
但是，关于 needn't 在间接引语中的用法，参见上面第148节C。
shan't／won't need to = shan't／won't have to
don't／doesn't need to = don't／doesn't have to
didn't need to = didn't have to（但 didn't have to 更常见）
从上面的表格中可以看出，与 haven't／hasn't got to 和 hadn't got to 完全同义的 need 的形式是不存在的。 |
