情态动词的本义用法总结(讲义)
如果从考察覆盖面最广的角度上来看,情态动词在考试中主要出现以
下的考法:
can/could强调客观能力/表示许可/推测
wi/woud体现主观意愿/表将来
my/mgt语气最弱,强调不确定的情况或较弱的可能性/表示许可
ust语气最强,态度非常坚决、情况非常确定、语气非常绝对
should提出建议/描述正常状态下的行为/描述在现有条件下将来即
将发生的事情
shall/ought to强调义务和责任,或命令与预期,语气较强
need提出需求,强调必要性
但是就像我们昨天说过的,情态动词一定在描述句中某个比较特殊的
情感态度语气。所以如果我们光探讨这些既彼此独立又互相有交集的功能
定义,掌握效果肯定会打折扣。咱们还是一起看看在过去的题目中这些东
西的用法,有个环境会更有体会一些。
在题目里考察理解最多的,应该是can/could和should。
can could
强调客观能力/表示许可/推测
should
提出建议/描述正常状态下的行为/描述在现有条件下将来即将发生
的事情
