I am going to Beijing, I have something to take to my parents, do you have something to be taken to your parents? 如果谓语表示的动作(情况)发生时, 不定式表示动作正在进行,这时候不定式就要用进行式.

To see is to believe. (对等) 注: 1). 不定式作主语时,谓语用单数 2). 当主语较长，谓语较短时，常用it做形式主语，而将不定式放到谓语的后面。 it做形式主语，不定式放在谓语动词之后常用于下列结构中: (1)It is/was +adj.+of sb. to do… (2) It is +adj.+for sb.+to do… It is easy / difficult / hard / foolish / unwise / right / wrong / unnecessary (3) it is +a +名词+ to do... It is a pity / a pleasure / a pleasant thing / one’s duty / an honor / a shame / a crime / no easy job… to do It takes (sb.) some time / courage / patience …to do… 欢迎广大教师踊跃来稿，稿酬丰厚。www.ks5u.com 2 高考资源网(www.ks5u.com)，您身边的高考专家 *注意: probable 和 possible 均可作表语，但possible可以用不定式作真实主语， 而 probable不能用不定式作真实主语。 错) 二、不定式做表语 主语是以aim duty hope idea intention plan job suggestion wish purpose task 等为中心词的名词词组 或以 what 引导的名词性从句表示，后面的不定式说明其内容, 不 定式作表语常表示将来或现在的动作或状态。 eg My idea is to climb the mountain from the north.
