2019高考英語備考 動詞時態和語態
be going to 表示現在打 算在最近或將來 要做某事，這種打算往往經過事先考慮，甚至已做了某種準備；shall / will do表示未事先考慮過，即說話時臨時作出的決定。
be going to 表將來，不能用在條件狀語從句的主句中；而will則能，表意愿。如：
if it is fine, we’ll go fishing.(正確)
if it is fine, we are going to go fishing.(錯誤)
be to do sth.表按計劃、安排即將發生的動作，還可表示吩咐、命令、禁止，可能性等。
a meeting is to be held at 3:00 o’clock this afternoon.
be about to do sth.表示“即可，就要”，后面不能接時間狀語或狀語從句。
autumn harvest is about to start.
（4）現在進行時考點分析。
①表示說話時正在發生著的一個動作；表示現階段但不一定是發生在講話時；表近期特定的安排或計劃；go、come等起止動作可用進行時代替將來時。如： it is raining now.
he is teaching english and learning chinese.
i am meeting mr. wang tonight.

at six i am bathing the baby.(i start bathing the bady before six.)
the girl is always talking loud in public.(與always、often等頻度副詞連用，表經常反復的行動或某種感情色彩)

（5）過去完成時考點分析（考核重點）。
①常用過去完成時的幾種情況：（a）在by、by the end、by the time、until、before、since后接表示過去 某一時間的短語或從句以前發生的動作。如：by the end of last year, we had produced 20,000 cars. the trai n had left before we reached the station. (b)表示曾實現的希望、打算、意圖、諾言等。常用had hoped / planned / meant / intended/
though / wanted / expected等或用上述動詞過去式接不定式完成式表示即：hoped / planned … + to have done。（c）“時間名詞 + before”在句子中作狀語，謂語動詞用過去完成時；“時間名詞 + ago”在句中作狀語，謂語動詞用一般過去式。如：he said his first teacher had died at least 10 years before. xiao hua left school 3 years ago.（d）表示“一……就”的幾個句型：hardly / no sooner / scarcely had + 主語 + 過去分詞 + when / than / before + 一般過去時。如：we had no sooner been seated than the bus started. = no sooner had we been seated than the bus started.
②在before或after引導的時間狀語從句中用一般過去時態代替過去完成時。
after he (had)left the room, the boss came in.

（6）過去將來時考點分析。
參照一般將來時對比：用would do、was / were going to do sth.表過去將來；c ome、go、leave等過去進行時表過去將來時；was / were to do sth.和was / were about to do sth.表過去將來。
