Unit3 The Computer and the Information Age-grammar教案
如: ---did you want me ? ----yes,i hoped you could give me a hand with the painting. 3》警示:除了表示明顯的過去時間狀語外,還有used to/would等暗示性詞語。 如:when i was in london, often,i would have a cup of coffee after work. 注意:上句中的would 不能用 used to 代替。這兩個詞雖然都表示"過去常常",但would 常和時間連用,如 often, every day 等,而used to 不可以。 3。一般將來時 1》概念 表示將來要發生的動作。 2》理解 對未來事情的預見性,或者說明意圖,打算。 <1> 用will 或shall +動詞的形式表示對未來事情的預見性,又稱為預見性將來時。 如: tomorrow will be fine . you will feel better after taking the medicine. <2> 用 be going to do表示將來。 用這種形式表示將來主要是說明現在的意圖,打算,即表明眼前最近要去做的事情。又稱之為近期將來。如:i'm going to post two letters after class./she is going to have a university degree. 如果這種結構用物做主語,也是一種預見,可以用will 代替。 如:it is going to rain watch out!the pill of boxes is going to fall. <3> 用be+going 表示將來 一般說來,用現在進行時表示將來所用的時間大都是動作動詞,不適用于狀態動詞。用這種結構表示按計劃要去做的事或發生的事情。 如:we're inviting several people to a party. the foreign ministry is coming to the un this week. the plane is taking off at 5:30 一般來說,be doing / be going to do 兩種結構均可以表示將來,但有些區別。 比較:i am taking mary out for dinner tonight . i am going to take mary out for dinner tonight. 第一句表示計劃已定不能改變,第二句表示打算未定只是一種想法而已。 <4> 用be+to do 表示將來時間 這種結構也可以表示按計劃,隨安排將要去做的事情或將要發生的動作。 如;the workers are to produce 5000 cars next year. the prime minister is to speak on television tonight. the line is to be open to traffic on october 1. 這種結構表示的將要發生的動作一般來說受人們意志控制或支配的。可以互換,但語意上有區別。如: we are going to play basketball this afternoon.<表示目前的意圖> we are to play basketball this afternoon.<表示計劃,安排或受人的支配>. 我們可以說:it's going to rain /the young man is going to be fat. 但不能說:it is to rain/the young man is to be fat.
