动词不定式省略to的9种情况

在感觉动词后，不定式作宾语补足语时，通常省略to。例如：I saw him leave the room.我看到他离开房间。She heard

the ___ ___.她听到孩子们在花园里唱歌。I felt the ground ___.我感觉到地面在我脚下震动。注意：感觉动词后的不定式如果有自己的宾语，则不省略to。例如：I saw him to leave the

room.我看到他离开房间。

注意：1.当help之后接一个较长的名词词组作宾语或当其中的不定式所表示的动作主语不直接参加时，不定式通常带to。例如：Help the little boys at the back of the hall to carry the

chairs out.请帮大厅后面那些小男孩把椅子搬出去。These

tablets will help you to sleep.这些药片将对你的睡眠有帮助。2.在当help用于被动语态时，不定式前的to不能省略。例如：Help is needed to clean up the mess.需要帮助清理这个混乱。

___ ___.

Fourth。n of "to" after "why (not)。"

___ infinitive after "why (not)。" cannot be followed by "to"。For example。"Why go with him?" and "Why not ask the

teacher?" In the sentence "Why not try to expand your story into a

novel?"。it should be "Why not try expanding your story into a

novel?"

Fifth。n of "to" after the verb "know"

In the structure "know + infinitive"。sometimes the "to" can

be omitted and sometimes it cannot。There are two ___:

"know" is in the present tense。the infinitive in this

structure is limited to "to be" and the "to" cannot be omitted。For

example。"I know him to be ill" and "We knew her to be honest."

"know" is in the past tense or perfect tense。the infinitive

in this structure can be any verb other than "to be"。and in this

case。the "to" can be omitted。For example。"I never knew him

(to) do such a thing" and "We've never known him (to) tell a lie."

However。in the passive voice。the "to" before the infinitive

cannot be omitted。For example。"I've never known it (to) snow

in July before."

Sixth。___ of "to" after "except/but"

After "except/but"。the "to" cannot be omitted.
