一般現(xiàn)在時態(tài)

1、在英語中，每句話都包含一定的時態(tài)，要學好英語就必須掌握英語中一些常用的時態(tài)。在英語中,不同時間發(fā)生的動作和情況,要用不同的動詞形式表示.這種不同的時間和不同的動詞形式就叫做動詞的時態(tài). 換句話說，判斷一個句子的時態(tài)，可以通過句子中的時間和動詞的形態(tài)來判斷。下面我就一般現(xiàn)在時作一些講解，如有不妥之處，請指教。每種時態(tài)都有三個最基本的要素，分別是該時態(tài)的概念、結構、判斷標志詞。一、 一般現(xiàn)在時的概念：一般現(xiàn)在時表示現(xiàn)在經常反復發(fā)生的動作、存在的狀態(tài)或習慣性的動作的時態(tài)。二、 一般現(xiàn)在時的結構：（有兩類不同的結構） Be動詞的一般現(xiàn)在時主語+be（am , is , are）+其它肯定句式：主語+b

2、e( am, is, are)+其它.否定句式：主語+be(am, is, are) +not +其它.一般疑問句：Be(am, is, are) +主語+其它？注：在這種構成中，be動詞有人稱和數(shù)的變化，即要根據(jù)主語選用am / is / are。Be動詞分為單數(shù)和復數(shù)，am和is是表示單數(shù)，am只跟I搭配（除了I其余的單數(shù)都用is），are表示復數(shù)。 實義動詞的一般現(xiàn)在時 主語（第三人稱單數(shù)）+動詞（第三人稱單數(shù)形式）+其它肯定句式：主語（第三人稱單數(shù)）+動詞（第三人稱單數(shù)形式）+其它否定句式：主語（第三人稱單數(shù)）+doesnt+動詞（原形）+其它.一般疑問句：Does+主語（第三人稱單數(shù)

3、）+動詞（原形）+其它？ 主語（除了第三人稱單數(shù)）+動詞（原形）+其它肯定句式：主語（除了第三人稱單數(shù)）+動詞（原形）+其它否定句式：主語（除了第三人稱單數(shù)）+dont+動詞（原形）+其它.一般疑問句：Do+主語（除了第三人稱單數(shù)）+動詞（原形）+其它？注：do、dont和does、doesnt是構成一般現(xiàn)在時的助動詞，其特點是要在其后跟動詞的原形。 三、 一般現(xiàn)在時的判斷標志詞often , usually , always , sometimes , at times , once a day , every + 時間 四、 動詞的第三人稱單數(shù)的構成規(guī)則和發(fā)音規(guī)則：1. 一般在動詞后直接加

4、上-s。在清輔音后發(fā)音為s，在濁輔音及元音后發(fā)音為 z。如：stopstops s ; makemakes s readreads z ; playplays z2. 以“s, x, ch, sh”結尾的，在詞尾加“es”，發(fā)音為iz 如：teachteaches iz; watchwatches iz3. 以輔音字母加“y”結尾的，要先將“y”變?yōu)椤癷”，然后在加“es”讀iz 如：flyflies z；carrycarries z；studystudies z; worryworriesz4以“o”結尾的動詞，加“es”，讀z 如：gogoes z dodoes z5. 還有個別動詞的第三

5、人稱單數(shù)是不規(guī)則的，例如：have has注：請思考一下動詞的第三人稱變化與名詞的復數(shù)有什么異同點。 五、 一般現(xiàn)在時的基本用法1) 經常性或習慣性的動作，常與表示頻率的時間狀語連用?！纠纭浚?.
