The
Gerund 動名詞
The gerund is the verb form ending in -ing. It functions
as a noun.動名詞是有 'ing' 形式的動詞,而作名詞用。
---e.g. She enjoys listening
to music.
-------- He admitted
breaking the window.
-------- We suggested going
to Yuen Long.
1.
Gerunds are used after the following verbs and expressions: 以下動詞和詞語後用動名詞
----admit, avoid, cannot help, consider,
deny, dislike, enjoy, finish, forgive, imagine, keep, mind, practise, resist,
----suggest, is worth, feel like, look forward
to, it is no use
---e.g. She cannot
help crying.
--- -- ---He considered
changing my job.
--------- Would you mind
answering a few questions?
--------- The food is
not worth eating.
--------- It is no use
crying over spilt milk.
---------
2.
Use gerunds after prepositions: 介詞後用動名詞
---e.g. The doctor told
him to give up smoking.
--------- You need
good shoes for walking on the hills.
--------- After having
made a decision, she told her parents.
3. Some verbs are followed by either the infinitive or the gerund without
much difference in meaning: advise, attempt, begin,-cease,
continue, intend, plan, propose 某些動詞後可用不定式或動名詞而意思沒有多大分。
---e.g. We are attempting
to climb the Lion Rock.
--------- I attempted
walking until I fell over.
4. There can be a difference in meaning when the infinitive or the gerund
is used after some verbs. In general, we use the gerund for ----habits
or past actions, the infinitive for present or future events. These verbs
are: dislike, forget, forget, hate, like, love, prefer, -regret,
remember.
某些動詞後用不定式或動名詞時,意思有不同。通常,動名詞用於習慣或過去動作,不定式用於現在或將來事件。
---e.g. Don't forget
to lock the door when you leave. (future action)
--------- I forgot
taking the pill yesterday. (past action)
--------- She likes
to live in England when she retires next year. (future action)
--------- I like
watching television. (habit)
--------- I regret
to tell you that you have not been selected. (present action)
--------- I regret
missing the great show. (past action)
5. After the verbs of perception, see, hear, smell, feel, notice, watch,
observe, either the infinitive or the gerund can be used. -When
using the infinitive, we are more interested in the completed action. When
using the gerund, we are more interested in the -progress
of the action.
知覺動詞後可用不定式或動名詞。用不定式時,我們注重動作之完成;用動名詞時,則注重動作之進展。
---e.g. I heard
him come in last night (so I know that he did come in).
---------I heard
him coming in last night (and he made a lot of noise).
---------I saw him
work in the garden yesterday (so I know he did work here yesterday).
---------I saw him
working in the garden yesterday (and noticed how interested
he was in it).
