D)“be to do”的5種用法:
a) 表示“按計劃、安排即將發(fā)生某事或打算做某事”。
例:She is to be seen in the lab on Monday.(星期一你準會在實驗室見到她。)
b) 該做或不該做的事情(語氣上接近于should, must, ought to, have to),表示一種命令、規(guī)勸性語氣。
例:You are to go to bed and keep quiet, kids. Our guests are arriving in less than 5 minutes.(孩子們,你們必須 上床睡覺,不準吵鬧。我們的客人5分鐘之內(nèi)就要到了。)
c) 能或不能發(fā)生的事情(接近can, may醫(yī).學全.在.線網(wǎng)站m.gydjdsj.org.cn)
例:How am I to pay such a debt?(我怎么可能還得起這么大的一筆債呢?)
d) 不可避免將要發(fā)生的事情,后來將要發(fā)生的事情。
例:I assure you that the matter _______ as quickly as possible. Have a little patience.
A. will be attended B. will be attended to
C. is attended D. is attended to
will be attended to關鍵的一點是:attend表示“處理,解決”時是不及物動詞,必須與to連用。另外,從上下文看,事情顯然尚未解決,所以應該用將來時的被動語態(tài)。答案是B.
A) is to be B) can be C) will be D) has been
答案是A) is to be.全句的意思是:“如果要避免食品短缺,就必須作出更大努力來增加農(nóng)業(yè)產(chǎn)量!
E) 同樣可以表示“正要、將要”的意思的句型是be on the point of doing. The coach is on the point of giving up the game because our team has been scored 7 points.
注意:
在 以if, when, as long as, as soon as, after, before, in case, until, unless 等連詞以及具有連詞作用的副詞(immediately, the moment, directly)等引導的狀語從句,一般用現(xiàn)在時代替將來時。強調(diào) 延續(xù)性或動態(tài)時,可用完成時。
例:I hope his health will have improved by the time you come back next year.(我希望到明年你回來的時候,他的身體已經(jīng)好多了。)
10. 將來進行時(will be doing) 調(diào)在將來的某個具體時間正在發(fā)生的動作或事情醫(yī).學全.在.線網(wǎng)站m.gydjdsj.org.cn。
ex: Don't worry, you won't miss her. She will be wearing a red T-shirt and a white skirt at that time.
11. 將來完成時(will have done) 表示從將來的某一時間開始、延續(xù)到另一個將來時間的動作或狀態(tài),或是發(fā)生在某個將來時間,但對其后的另一個 將來時間有影響的動作或狀態(tài)。就好象把現(xiàn)在完成時平移到時間軸的將來時時段一樣。其用法從和過去及現(xiàn)在有關,變成了和將來及將來的將來有關。
ex: It is reported that by the end of this century the people of Chinese will have increased by 2 billion.
