????Ⅰ動詞(時態(tài),語態(tài),用法,省略,一致性等)

????時態(tài)

????1)現(xiàn)在完成進行時態(tài) (have/has been + -ing 分詞構(gòu)成): 動作或狀態(tài)從過去某時開始,繼續(xù)到現(xiàn)在,可能繼續(xù)下去,也可能剛剛結(jié)束.

????I’ve been writing letters for an hour.

????I’ve been sitting in the garden.

????2)過去完成進行時(由had been + ing分詞構(gòu)成): 過去某個時刻以前一直在進行的動作

????I’d been working for some time when he called.

????We had been waiting for her for two hours by the time she came.

????3)將來完成進行時: 將來某個時刻以前一直在進行的動作.

????語態(tài)

????可以有兩種被動結(jié)構(gòu)的類型,例如:

????He was said to be jealous of her success.

????It was said that he was jealous of her success.

????能同時適用于上述兩個句型的主動詞通常都是表示“估計”,“相信”等意義的動詞,常見的有assume,believe,expect,fear,feel,know,presume,report,say,suppose,understand等.

????It is supposed that the ship has been sunk.

????The ship is supposed to have been sunk.

????擔(dān)當be supposed to 與不定式的一般形式搭配時往往表示不同的意義.例如:

????Why are you driving so fast in this area? You are supposed to know the speed to know the speed limit. (你應(yīng)該曉得速度限制)
