三,拓展内容
(一)同义替换
情态动词:have to→must(在表示 “必须” 时,客观必须用 have to,主观必须用 must,部分场景可替换,
例:You have to/must finish the work on time.)
祈使句:Don't do sth.→You mustn't do sth.(
例:Don't run in the hallways. = You mustn't run in the hallways.)
情态动词:can→be able to(can 只有现在时和过去时 could,be able to 有多种时态,
例:He can swim. = He is able to swim. / He will be able to swim next year.)
四,考点总结
易错点重点突破
祈使句否定式的错误构成,
Be 型祈使句否定式误写为 “Not be...”,
正确应为 “Don't be...”;
Do 型祈使句否定式漏写 Don't,
直接用动词原形加 not。
情态动词 have to 的人称和时态变化错误,
第三人称单数误用 have to,过去时误用 have to,未正确变为 has to 和 had to。
can 和 may 的混淆使用,两者都可表许可,
may 语气更正式,can 更口语化;
can't 和 mustn't 的区别,can't 表 “不能(能力)” 或 “不可以(许可)”
mustn't 表 “禁止”,语气更强。
