标题: Grammar问题
本帖最后由小恋心于 2013-6-19 10:24 PM 编辑

想请问各位，要如何学好grammar问题？还是可以请各位高人可以教我吗？

例如：1.to后面要放回原本字
2.正在进行式是ING
3.也有分past tense and present tense
还有什么是需要注意的呢？

PS：还有一个问题，have been?had been?has been?
been是在什么情况用的呢？

Present Perfect:

Present Perfect用在過去不明時間點上的事情(時間點不重要)所以不能夠和類似上個禮拜,去年..一起使用
例子:
I have been to Taiwan.
I have seen her wearing that dress before.

Past Perfect

用在描述發生在一個事件前的事情
例子:
I had never seen a tiger before I went to zoo.
She had never eaten nasi lemak before she came to Malaysia.

PS:Been 只是 Be (is/am/are 的base form verb)的past participle,也就是說had/have/has been可以變成has/have/had seen/eaten/taken...任何的past participle

例如：

1.to后面要放回原本字
是的，to的后面如果是动词(verb),要放原本的字 (root word), (e.g., to eat, to play, to find)

2.正在进行式是ING
可以分成几种，比如
Present Continous tense (e.g., I am eating/playing/listening/thinking) --指现在进行，比如下午2pm
Past Continous Tense (e.g., I was eating/playing/listening/thinking) ----过去2pm这段时间在进行中，通常past continous 用在duration比较长的动作，如果duration短，直接用past tense (e.g., I found something)

还有另外一个情况是
I like listening to songs.
I love eating fruits.
I go jogging with friends

第一个verb + 第二verb同时出现的时候，第二个verb需要+ing

3.还有一个问题，have been?had been?has been?
Have/Has been是Present Participle, 是用在Passive Voice的句子，（passive=被动式）
如：I have been teaching in this secondary school since 1999. (这个是Present Participle Continous)
意思是，我从1999到现在都在这所中学教书。

另外一个相同的example,
He/She has been teaching in this secondary school since 1999.

至于Had been用在Past Participle Continous的句子里

还有另外一个Example
Present Perfect Tense
如：I have been told to participate in this event. (我刚刚被通知参加这项活动,比如说这件事情的发生在刚才2pm)

Past Perfect Tense
如：I had been told to participate in this event. (昨天、前天或很多天前的大约2pm，我被通知...)
