It's going to rain, I think. (有迹象要发生的事情)3. be doing代表现在进行时。
现在进行时表示即将发生的将来,多与表示位移的动词come, go, arrive, leave, fly, start等连用例如: She is leaving for Beijing. 她就要启程去北京 4. 一般现在时表示将来时,主要用于时间状语从句或条件状语从句中;或者用来表示按时刻表的规定将要发生的动作例如: I'll tell him about it as soon as I see him. My plane takes off at seven tomorrow morning.形容词及其用法形容词修饰名词,说明事物或人的性质或特征通常,可将形容词分成性质形容词和叙述形容词两类,其位置不一定都放在名词前面1) 直接说明事物的性质或特征的形容词是性质形容词,它有级的变化,可以用程度副词修饰,在句中可作定语、表语和补语例如:hot 热的2) 叙述形容词只能作表语,所以又称为表语形容词这类形容词没有级的变化,也不可用程度副词修饰大多数以a开头的形容词都属于这一类例如:afraid 害怕的错) He is an ill man. (对) The man is ill. (错) She is an afraid girl. (对) The girl is afraid. 这类词还有: well,unwell,ill,faint,afraid,alike,alive,alone,asle。
