动词的第三人称单数形式
再加 -es. 例如:
•
study- --studies ,try---tries ,
•
carry---carries,fly---flies ,
•
copy---copies
•注意
•除了上述基本规律之外,英语中还存在一些无 规则的第三人称单数变形。这些需要我们特别 记忆,如:
• go ---- goes • do ---- does • have ---- has
•
肯定句变否定:
•1. 找 is , am ,are , can等词。变否定更容 易,词后not莫忘记。
•2.添:动词是原形,动词前加don’t
•
动词是第三人称(-s)在动词前加
doesn’t,动词变原形
•3.如果还有some在,快用 any换过 来。
变否定
1. I am a new student. 2. 否定:
