[误] He was seen come into the book store.
[正] He was seen to come into the book store.
[析] 在主动语态中,有时可以加不带to的不定式作宾语,如:I saw him come into the book store.但如果变为被动语态时,则要将省略的to还原。当然这些动词还可以加动名词作宾语,如: I saw him coming into the book store, 如变为被动语态时,则没有变化。如:He was seen coming into the book store.

[误] Is this book yours?
Yes, It's.

[误] He asked me do my homework alone.
[正] He asked me to do my homework alone.
[析] 某些动词要求不定式作其宾语或宾语补足语,它们是:ask somebody to do something 要求某人做某事。 tell somebody to do something 告诉某人做某事 还有prepare 准备, decide 决定, happen to 碰巧, seem 似乎。

[析] 要学会疑问词加不定式的用法,特别要注意的是what是疑问代词,而how是疑问副词。如:I want to know what to do. (我想知道干什么)。 I want to know how to do it. (我想知道如何去作)。 要注意的是how to do it 中的it是不可少的,因how是疑问副词,不能作及物动词的宾语,而what是疑问代词,可做do的宾语,所以what to do 后不要加it。
[误] I am very glad meeting you.
[正] I am very glad to meet you.
[析] 许多形容词后加不定式,这样用时形容词多是用来描述人物的感情、态度,如:glad, happy, pleased, lucky, sorry, sad, upset, ready, careful, surprised。
[误] I'm too glad for seeing you.
[正] I'm too glad to see you.
[析] 这句话不能按照too…to的句型翻译为:我太高兴了以至于不想见你。而应译为:见到你太高兴了。又如:She is too honest to tell the truth? 应译为:她很诚实,不会不讲实话。

[误] Could you help me to find a chair to sit.
[正] Could you help me to find a chair to sit on.
[析] 当不定式作后置定语时,将不定式放于名词之后。如果不定式中的动词是不及物动词,则其后面的介词不要省略。如:I sat on the chair. 这样的用法还有:I want to find a room to live in. I want to find a pen to write with.

[析] 在不定式作宾语时,下列情况常用主动语态表示被动。① 句子的主语即是不定式动作的执行者,如:I have a lot of letters to write. ② 句中的宾语是不定式中动作的执行者,如:Could you find me a job to do? ③ 在形容词之后的不定式,如:English is difficult to learn.
[误] Would you like to see a film with us? Yes, I'd love.
[正] Would you like to see a film with us?Yes, I'd love to.

[正] In autumn, the street is always covered with fallen leaves.
[析] 现在分词作定语有正在的含义,如:falling leave 正下落的叶子。而过去分词作定语fallen leaves是落地的叶子。过去分词含有已经完成的意思。
[误] Do you hear someone sing in the office?
[正] Do you hear someone singing in the office?

[误] I want to shop some food for supper.
[正] I want to buy some food for supper.

[误] When the teacher came into the classroom, the students stopped to talk.

[误] I didn't remember closing the door, so the thief came into the room directly.
[正] I didn't remember to close the door, so the thief came into the room directly.
[析] remember后接不定式是记着去做某事,即该动作并没有完成。而remember 后接动名词则表明该动作已经作完了。如: Do remember to turn off the light, before you leave. 即在你离开前记着去关灯。而关灯的动作并没有做。I remember meeting you somewhere. 我记得在某处见过你。而相见一事已经作完了。相同用法还有forget。
[误] When I finished to do this work I would go to play football.
[正] When I finished doing this work I would go to play football.
[析] 在英语中有些动词后要接动名词作宾语。在初中范围主要有两个动词finish和enjoy, 千万不要与like相比。因为like作动词"喜欢"用时,其后接动名词表示习惯性动作,接不定式表示一次性特殊的动作,而would you like后面则一定要用不定式。
