动词变三单的规则与名词复数规则一致。请转到:Lesson 055&56 The Sawyer family查看详细说明!
| 句型 | Be 动词 | 动词原型 | 动词三单 |
|---|---|---|---|
| 陈述句 | He is happy. | You like English. | She likes Chinese. |
| 否定句 | He is not happy. | You do not like English. | She does not like Chinese. |
| 一般疑问句 | Is he happy? | Do you like English? | Does she like Chinese? |
| 特殊疑问句 | How is he? | What do you like? | What does she like? |
“现在”可以理解为狭义的现在与广义的现在,区分为此刻与现阶段。现在进行时常与 now,just,still 等副词连用。
| 句型 | 现在进行时 | ||
|---|---|---|---|
| 陈述句 | He is listening. | You are drinking. | She is walking. |
| 否定句 | He is not listening. | You are not drinking. | She is not walking. |
| 一般疑问句 | Is he listening? | Are you drinking? | Is she walking? |
| 特殊疑问句 | What is he doing? | What are you doing? | What is she doing? |
在英语中,动词 "be" 在现在进行时的口语中通常缩写为 "'s"。例如,"He is listening" 可以缩写为 "He's listening"。书面语通常不缩写。
| It is a terrible day! | What a terrible day it is! | What a day (it is)! |
| 原句 | 感叹句(完整) | 感叹句(省略) |
有上下文和一定的语境, 才能省略形容词。一般省略形容词表示批评或不大好的意思。在英语中可用what引导的感叹句来表示惊奇、愤怒、赞赏、喜悦等感情,在感叹中主谓语采用正常语序。
