在中文，我們常說“我是愛你的”，翻成英文，這就變成了 ＊ I am love you. 滑稽的是，這句英文句子犯了大忌，因?yàn)楱攁m〞是動詞，〝love〞也是動詞，兩個(gè)動詞是不能聯(lián)在一起用的。這句話的正確說法是： I love you. 或者 I am in love with you. 我們中國人也會說〝我喜歡看電視〞，翻成英文，這變成 ＊ I love watch television. 這個(gè)句子也犯了同樣的錯(cuò)。 以下幾個(gè)句子都是錯(cuò)的，因?yàn)檫@些句子中都有兩個(gè)動詞連在一起的情形： ＊ I hate eat fish. ＊ I love play basketball. ＊ I love swim. 如果你一定要講“我愛游泳”，怎么辦呢？請看以下的規(guī)則。
“我愛游泳”，因此有兩種正確的譯法： I love to swim. I love swimming. 以下的句子都是正確的： I hate to eat fish. I hate eating fish. I love to play basketball. I love playing basketball I keep going to church.
規(guī)則（３）：主詞如果是第三人稱，現(xiàn)在式及單數(shù)，動詞必須加s.
我們中國人最不容易記得的規(guī)則，恐怕就是這一條了，以下的句子都是錯(cuò)的。 ＊ He write very well. ＊ Jack love playing the violin. ＊ Mary swim every day. 正確的句子是： He writes very well. Jack loves playing the violin. Mary swims every day. 規(guī)則（４）：絕大多數(shù)的否定的句子，不能直接加“not”。
我們中文對否定語氣，規(guī)則極為簡單，我們可以說“我不愛你”，但是我們不能說 ＊ I not love you. 我們也不能說： ＊ I not saw that movie. ＊ I not like swimming. ＊ He not likes playing violin. 我們必須用一種助動詞來完成否定的句子，以下才是正確的否定句子： I do not love you. I did not see that movie. He does not like playing violin. 請注意，在以上的句子中，do和did都是助動詞，do是現(xiàn)在式，did是過去式。 關(guān)于現(xiàn)在式和過去式，究竟是怎么一回事，以后我們會解釋清楚的。 助動詞不限于“do”和它的變型，can、will、would、shall、may、must等等都是助動詞，因此，以下的英文句子又都是對的： He can not swim. They will not go to church tomorrow. Mary should not go to the party. I shall not see you. He may not go out tonight. He must not eat meat any more.
規(guī)則（５）：在不定詞“to”的后面，必須用原形動詞
英文中的動詞，是會變化的，以have為例，第一人稱和第三人就不同： I have a dog. He has a dog. 如果是過去式，動詞又要變化。have的過去式是had，不論第幾人稱，一概都要用had。 幾乎每一個(gè)英文動詞的過去式都有變化，以下是幾個(gè)例子： 現(xiàn)在式 過去式 go went come came eat ate play played swim swam 不論那一個(gè)動詞，都有一個(gè)原形動詞，一切都是從這個(gè)原形動詞變出來的，像go、drink、have、walk、love、like等等都是原形動詞。 如果我們有必要要用不定詞to，就必須用原形動詞，例如to go、to drink、to have，都是正確的，＊to went；＊to drank；＊to loved等等都是錯(cuò)的。 英文中有一個(gè)動詞最為麻煩，那就是am、are、is、was、were等等，翻譯成中文，這都是，而這些動詞的來源都是be，所以我們說這些動詞都是verb to be。 以下的句子都用上了〝be〞 I want to be a teacher. He wants to be a good father. They all love to be rich. No one likes to be poor. 規(guī)則（６）：英文中有所謂的助動詞。必須注意
英文中有很多動詞都是助詞動，在規(guī)則（４）中，我們說在絕大多數(shù)的否定語句中，必須用助動詞do或did。Do是原形動詞，did 和does都是do的變形。 除了do是助動詞以外，can、may、might、will、would、must也都是助動詞。 以上所提到的助動詞，都有一個(gè)共同的特色，那就是這些助動詞后的動詞必須是原形動詞，以下的句子都是正確的： He can swim. He does not swim. I do not speak English. You must walk to work every day. I did not work yesterday. You may leave now. I will go to Taipei tomorrow. 以下的句子都是錯(cuò)的： ＊ I did not went. ＊ He does not goes to work. ＊ You must walked to work. 除了以上的助動詞以外，還有一個(gè)非常特殊的助動詞，那就是have，在這個(gè)助動詞的后面，動詞絕對不能用原形動詞，以下是用這個(gè)助動詞的例子： I have been to England. I have slept all day. I have studied English since I was a child. been、slept 和studied都是過去分詞（past participle），以下的句子也都是現(xiàn)在完成式，我們后討論完成式的時(shí)候，會將這些解釋清楚的。
規(guī)則（７）：英文問句要有助動詞
我們先看看以下的英文句子，這些都是錯(cuò)的： ＊ How many books you wrote？ ＊ How many sons you have？ 正確的句子是： Why do you drink so much water？ How many books did you write？ How many sons do you have？ 絕大多數(shù)的英文問句子是一定要有助動詞，以下全是正確的英文問句，你可以看出每一句的助動詞嗎？ Do you love me？ Did you go to school yesterday？ How many books do you have？ How much money does he have？ Why don’t you go back home？ Do you like to swim？ Can you play violin？ Will you go home tomorrow？ Would you give me a call？ 當(dāng)然啦，一旦動詞是verb to be，我們又不需要助動詞了，以下都是正確的英文問句： Are you a teacher? Is he a student? Is Mr. Chang your father? Were your mother and father in England last year? 規(guī)則（８）：特殊動詞隨主詞的變化
英文中，有些動詞因主詞不同而改變，verb to be是其中之一，因此，我們必須記得以下的規(guī)則： 第一人稱 第二人稱 第三人稱 現(xiàn)在式 單數(shù) I am You are �。℉e，She，It）is 復(fù)數(shù) We are You are They are 過去式 單數(shù) I was You were （He，She，It）was 復(fù)數(shù) We were You were They were
Verb to have也有類似的變化： 第一人稱 第二人稱 第三人稱 現(xiàn)在式 單數(shù) I have You have （He，She，It）has 復(fù)數(shù) We have You have They have 過去式 單數(shù) I had You had �。℉e，She，It）had 復(fù)數(shù) We had You had They had
