to infinitive同gerund的用法

to infinitive:
如何用:

大部份情況下: to 之後既verb 都會用所謂'最原始', 即係咩都唔哂加...即係look 就 to look, see就to see, eat 就 to eat.
e.g.
1. I want to eat dinner.
2. I would like to have a piece of cake.
3. I go to the stationary shop to buy a pencil.


但當然有例外，最常為人知既例外情況，就係 I'm looking forward to xxxxing...

e.g. I'm looking forward to seeing again next year.
e.g. I'm looking forward to hearing your voice in HK.
呢個就要記住既...見到'looking foward to' 都應該用 gerund

何時用就無咩限架bor...
用黎有咩用? 就係講第一個動作會引致到下一個咩既動作...
e.g. I want(想:第一動作) to eat(想---> 去食: 第二動作) dinner
-------------------------------
gerund:
如何用:
中文譯為動名詞,簡單d講就係係動詞後面加 ing...

e.g. eat > eating, drink > drinking, watch> watching, kill> killing

但要留意，某d verb 要係加ing 變做 'double letter'
先舉例, e.g. beg > begging, put > putting, travel > travelling, run> running, stop> stopping, slam> slamming etc.

即係將個verb既最後一隻字double 左... 你就咁睇..係咪好似vowel 前面既最後一隻字，加ing 就要double??? 答案當然唔係, e.g. shout> shouting, play> playing.

何時用: 做緊個個動作既時侯
e.g. I 'm eating dinner. (我現時在吃晚餐.)
I'm watching TV. (我現時在看電視)
總之要係以加做緊既...

(唔夠位會係'意見'度繼續寫)

用黎有咩用: 就係要表示你自己真係'現在'做緊既~

唔好意思, gerund 其實仲可以用係 動詞之後...
e.g. I prefer travelling to France.
I love eating ice-cream.
呢個用法同'to infinitive' 既意思相同... 意即指我上面舉個兩例亦可用'to infinitive' 黎代替。 I prefer to travel to France/ I love to eat ice-cream. 意思無改變...

infinitive 不定詞 & gerund 動名詞 是non-finite verb.(包括participle分詞)=非限定動詞,不受
subject 的身和數所限制的動詞.

q1 :如何用?........因一英文句子中只須用單一的主動詞,其它附有動作性的詞
通通是 non-finite verb. 它們分別在句內演繹
verb,adj,adv.(noun as subject/object/complement.).

q2 :何時用?........只要一句內有多于一個動作就要出動.
eg...I go to swim. .....go是主動詞..... to swim是不定詞作adv形容go去何處?
eg...Have you any things to sell ?.....to sell as adj 你有要賣的東西嗎?
eg...To smoke is a bad habit. ........to smoke as SUBJECT.
eg...I wish to be a doctor. .......to be跟其它詞構成noun phrase as object.
eg...To see is to believe. ............as SUBJECT & OBJECT.
以上是infinitive = to + root form 其動作是遲于主動詞彧同時.as:noun,adj,adv.


以下是gerund = root form + ing 其動作是早于主動詞或同時.as:noun with action, not the Adj.
(past / present participle 才可作adj. / adv and verb.)
Gerund跟其它詞構成gerund phrase去作subject / object / complement.
及在介詞後構成 prep. phrase去形容句前.

eg... Hunting tigers is very dangerous. .....as SUBJECT.
eg...We enjoy playing table- tennis...........as OBJECT.
eg...His bad habit is drinking wine.........as COMPLEMENT.
eg...John has a bad habit of spitting everywhere 作 介詞短語.

唔使再講相信你已明白. 我是否解得好過老師呢?
