【摘要】：在一般现在时中，do 有人称的变化，第三人称单数用 does，一般过去时 do 变成 did。其他时态的强调通过重读谓语动词来体现。My father smokes a lot. → My father does smoke a lot.
第二节 强调谓语动词
用“助动词 do + 动词原形”来强调谓语动词。
注意：谓语动词只有两种时态能强调，即一般现在时和一般过去时。在一般现在时中，do 有人称的变化，第三人称单数用 does，一般过去时 do 变成 did。其他时态的强调通过重读谓语动词来体现。
例如：
You’re quite wrong?she does like you. 你错了，她真的喜欢你。
Do come in. 快进来。
用“助动词 do + 动词原形”来强调谓语动词。
1.强调一般现在时动词谓语
例如：
I work hard. → I do work hard.
She loves you. → She does love you.
My father smokes a lot. → My father does smoke a lot.
2.强调一般过去时动词谓语
例如：
I called you in the morning.
→ I did call you in the morning.
I attended the meeting yesterday.
→ I did attend the meeting yesterday.
I handed in the paper yesterday.
→ I did hand in the paper yesterday.
He wrote a letter to me yesterday.
→ He did write a letter to me.
He came to see you yesterday.
→ He did come to see you yesterday.
