一道史上巨难英语短文改错题-----解释不清楚的请勿回答,
I hardly remember my grandmother.She used to holding
me on her knees and sing hold old songs.I was only four when she
passed away.She is just a distant memory for me now.
【I remember my grandfather very much.He was 】
tall,with broad shoulders and a beard that turned from black
to gray over the years.He had a deep voice,which set
him apart from others in our small town,and he was strong
and powerful.In fact,he even scared my classmates away
when they came over to play or do homework with me.How-
ever,he was the gentlest man I have ever known.
【】里的句子有问题,答案是much改为well.
我搞不懂.为什么要这样改.very well与evey much有区别吗?
我们经常看到I love you very much.和 I know him very well.这样的句子.谁能解释清楚.
还有一篇类似的短文改错
Most students study English hard at school but they
only use the time to study the rules of the language and
new words.They spend a lot of time on exercises.They
【don’t like reading English much.Actually,reading】
for pleasure is an easier way to learn English well.
Many experts say reading for pleasure helps students
to learn many important things about English.
For example,students can learn more about the
cultures of English-speaking countries.What’s more,
they can learn how to use English more properly.
much前加very.难道very much 和much也有区别.
附上例句

第一个很简单,根据句面意思即可理解.remember,know是记得,知道的意思,用well表示程度.而love用much表示多少.这样就可以理解了.
第二个感觉very much和much没什么大的区别,much本身可以做副词.但是在(表示行动、感情或变化的强烈程度,通常和 so,too,very 一起用于否定句中)很多,非常 .
再问： 第一个，remember 不可以用very much表多少吗？ 第二个， They don’t like reading English very much. 这个句子中very much 是表示“行动”吗？
再答： remember是记得，应该说记忆深刻，而不是记忆很多，如果是那样的话建议你用miss sb much，而不是remember sb much。 不是行动，是表示感情，因为是like，建议你去iciba看一下much的用法，要看下面的英文解释。
再问： I love you very much. 这个very much不是说用于否定句吗？这个句子怎么是肯定句？解释一下好吗？
再答： 这里的much是表示程度的。就跟thank you very much的用法一样。而且是固定用法，你看欧美电影就知道了。
再问： iciba 上说，与very,too等一起用于否定句。这里的明明是肯定句。是不是矛盾了？
再答： 不矛盾，就像我上面说的，有些肯定句是固定搭配的，也表示情感，比如爱，感谢等。但是喜欢的时候确实就可以用否定了。比如： I don;t like it that much。我并不是那么喜欢它。
