二、核心句型。

3. anyway, it's good to see the amazing changes in the town.

不管怎样,看到小镇这些令人吃惊的变化还是很好的。

考点点拨]“it's+adj. (easy,important,bad,nice…)+for sb.) to do sth”是英语中应用非常广泛的一个句型,意为“(对某人来说)做某事是(容易的,重要的,坏的,好的……)其中it是形式主语,无实际意义,真正的主语是后面的动词不定式to do sth。

如:it is important for us to master a foreign language.

掌握一门外语对我们来说很重要。

三、重点语法。

现在完成时。

1.基本结构为:助动词h**e/has+动词的过去分词。

1)表示过去发生的行为、动作或情况对现在造成的影响或结果。时间副词常用just(刚刚),already(已经),still(仍然),recently(最近),yet(还、尚),ever(曾经),never(从不)。其中just,already用于肯定句;yet,ever,never常用于疑问句或否定句;still,recently可用于肯定句、否定句或疑问句。

如:h**e you ever been to hong kong?

你曾经去过香港吗?

i h**en't got the letter from my uncle yet.‘

我还没收到我叔叔的信。

2)表示从过去开始并持续到现在的行为、动作或情况。常与for或since引导的时间状语连用。for表示一段时间,后接时间段.;since表示“自从”,后接时间点。

(3)也常与so far(迄今为止),in the past several years(在过去几年里),ever since(迄今),in/during/over the past/last few years(在过去几年里)这类从过去到现在的时间状语连用。在此类句子中,谓语动词要用持续性动词,而不能是短暂性动词。如:

the children h**e been away from home since the new term began.(木用left)

自从新学期开始,孩子们就已经离开了家。

2.具体的几组时间短语辨析。

ago用于一般过去时(用瞬间动词);since...ago用于现在完成时;in the past用于一般过去时;in the past few years用于现在完成时;just now(置于句末)用于一般过去时;just(置于句中)用于现在完成时。如:

i bought this dictionary three years ago.

i h**e had this dictionary for three years.

i h**e had this dictionary since three years ago.

这本字典是我三年前买的。

还可以用“it is/has been+时间段+since从句”改写为:

it is three years since i bought this dictionary.
