第9講：時態一
提起時態，當然是指動詞的時態啦。過去、現在和未來等不同時間段發生的事情要用不同的時態來表示。時態是動詞的一種形式，表示動作或狀態發生或存在的時間和方式。閉上眼睛想一想，初中我們學過的時態有幾個? 初中我們共學過八種時態。本講將這幾個時態總體介紹一下:
一般現在時：常與always,often,sometimes, every day連用，表示習慣或經常反復發生的動作或存在的狀態。提醒你當第三人稱單數做主語時，別忘了動詞的變化。注意：象"地球大，月亮小"等客觀真理、事實一定用一般現在時。
現在進行時：要注意其構成：由be+動詞+ing,表示說話時正在進行的動作。如：We're studying now. 我們現在正在學習。
一般過去時：表示過去某個時間發生的動作或存在的狀態，常與yesterday,last year,in 1949,two years ago,等表示過去時間的狀語連用。注意：We often went to dance last summer.有的同學一見到often就想到用一般現在時，其實因為后面有表示過去時間的 last summer,所以要用過去式，千萬別誤用了，切記，切記。
過去進行時：顯然過去進行時表示過去某一時刻正在做什么，常和特定的時間狀語如at that time，at six yesterday，at that moment，when he came in等連用。如： When he knocked at the door,his mother was cooking.
一般將來時：表示將要發生的動作或存在的狀態，常與表示將來時間狀語如 next year,tomorrow等連用。注意：在Will you ....?問句中，回答必須是 Yes,I will.或 No,I won't而不能用Yes,I shall. No, I shan't.來回答過去將來時：過去將來時不可以單獨使用，它一般在賓語從句中作間接引語，表示從過去某一時間看來將要發生的動作或存在的狀態。如：They told me that they would go to work in Guangdong.
現在完成時：顧名思義，現在完成時表示的是已經完成的動作，但動作造成的影響還在，常被just,already,yet 等副詞修飾。如：He has already gone to Tianjin. 對現在造成的影響是他已經不在這兒了。現在完成時還可用來表示過去發生的動作一直延續到現在，常帶有for或since等表示一段時間的狀語。如：Mr Wang has lived here since 1983.表示說話前發生過一次或多次的動作，我們常用"過"來表示，常帶有twice, once, ever, never等時間狀語。如：I've never seen that film.
過去完成時：我們可以用"過去的過去"來概括過去完成時，表示過去某一時刻或某一動作之前已經完成了的動作，通常與by,before等構成的短語或when, before, after引導的從句連用。也可表示過去某一時間開始，一直延續到過去另一時間的動作，常和for或since構成的時間狀語連用。用法和現在完成時大致相同，只不過又向前推了一個時態。
八個時態可能得讓你好好對付一陣子，但細細學來，也并不困難。不信嗎? 試試趁熱打鐵你就知道了。
