英文文法:equal加不加s的問題

01.What does 99 multiplied by 9 equal?

02.15 multiplied 269 equals 4035.

03.What's 7 and 8?

04.What are three tens?

05.What does 15 times 269 make?

請問:

01.為什麼問句時的〝equal〞不加〝s〞?

02.為什麼肯定句時的〝equal〞加〝s〞?

03.它是因為屬於第三人稱單數動詞加〝s〞的嗎?

還是他是屬於什麼詞?有另外加〝s〞的意義?

04.上面的 03 ~ 05的問句l:

什麼時候該用be動的 is?

什麼時候該用be動的are?

什麼時候該用助動的 does?

請各位高手幫幫忙 解釋詳細一點!

    1. 問句時前面有助動詞 does,助動詞 does 後面的動詞一定是原型

    2. 15 multiplied by 269 這一整段視為單數,所以equal要加s

    3. 沒錯,加 s 就是因為第三人稱單數

    equal 可以當作動詞和形容詞,形容詞的用法是 be equal to,意思與動詞 equal 一樣。

    例如: 2 plus 3 is equal to 5 = 2 plus 3 equals 5

    在英文裡面第三人稱單數動詞的現在式都要加 s ,這是文法規定。(這已經很好了,西班牙文和法文中三個人稱的單複數形式各有不同的變化,也就是每個時態就有6種變化。所以學英文已經很簡單了啦!!)

    be動詞變化

    I am/was/have been

    You are/were/have been

    He/she is/was/has been

    助動詞 do 只有在第三人稱單數的現在式才會變成 does,第一人稱與第二人稱單數的現在式都是 do
