三. 语法复习：
现在完成时的时间状语
（1）现在完成时属于现在时范围，故不能和过去的时间状语连用。

如：yesterday, last
Sunday,in1990,three years ago等。

但是，在强调动作产生的后果和影响时，可以和一些表示不确定的时间状语连用(ever, never, just, already, yet)。

a. 用副词already和yet。

already一般用于肯定句中，yet一般用于否定句和疑问句中。

如：We have already finished our homework.我们已完成作业了。

They haven't finished their homework yet.他们还没有完成作业。

b.用ever 和never。

多用于否定或疑问句中，表示“曾经”或“从未“等。

如：-Have you ever been to the Great Wall?你曾经去过长城吗？
-I have never been to the Great Wall.我从未去过长城。

c.用表示到说话为止的过去时间状语，如just,before,up to now,the past few years等。

例如：I have seen her before, but I can not remember where. 我以前见过她，但记不起在哪里见过。

He has been there three times the last few days. 近几年他去过那里三次了。

d.用包括“现在”在内的时间状语，如：now,today,this morning(month,year,term)等。

例如：-Have you met him today?-No,I haven't. 今天你见过他吗？我没有。

How many times have you been there this year? 今年你去过那里多少次？
语法练习题（ever, never, just, already, yet填空）
1.Have you ______been to London?
2.They've _______ arrived.
3Our visitors have _______come. 4.Is everything ready _______?
5.I have _____been to HK.
二、分数
1.分数的写法：分数中分子用基数词表示，分母用序数词表示。

先读分子，后读分母。

当分子大于1时，分母要加“s”。

例如：
1/3读作：a／one third
2/3读作：two thirds
2.分数的用法：分数做主语时，谓语动词用什么形式需要判断分数后面“of + 名词”中的名词的形式。

如果of后面是可数名词单数形式，则谓语动词也用单数形式（三单）；
如果of后面是可数名词复数形式，则谓语动词也用复数形式；
如果of后面是不可数名词，则谓语动词也用单数形式（三单）。

练习：1.Three fifth of the population in China＿＿＿＿farmers. 1.is 2.are 3. have 4.has
2.Two thirds of the water _______in the bottle. 1.is 2.are
3.do
4.does
三、so do I和so I do 用法和区别
1.So do I的用法：该结构主要用来说明前面所说的情况也同样适用于后面的人或物，[意为“……也一样”]。

前后句的主语指的不是同一个人或物。

该结构中的助动词do 根据前文的情况也可换成is, am, are, was, were, does, did, can, could 等。

如：He passed the exam, and so did I. 他通过了考试，我也通过了考试。

但是如果前面所述为否定式，则用neither, nor引出倒装句(此时不能用so)。

如：He couldn’t do it, and neither could she. 他做不了这事，她也做不了。

He never comes late. Nor do I. 他从不迟到，我也从不迟到。

2.So I do的用法：该结构主要用于加强语气，其意为[“的确如此、确实如此”]，表示后者赞同前者的话或意见，只是进一步强调并重复前句所述的内容。

前后句的主语指的是同一个人或物。

该结构中的助动词do 根据前文的情况也可换成is, am, are, was, were, does, did, can, could 等。

如：—He has done a good job. 他干得不错。

—So he has. 他的确干得不错。

Life in the 21st century will be different from life in the 20th century, because many changes will take place in the new century. But what will the changes be?

Work in the future will be different, too. Dangerous and hard work will be done by robots(机器人). Because of this, many people will not have enough work to do. This will be a new problem.
