Dear Jenny,
I’m so worried when I see that you’re not a little tired and nervous about the coming College Entrance Examination; Here is some advices to help you prepare the coming exam.
Have enough sleep, whatever much work you have to do，or you’ll feel sleepy on an
occasion in class. A balanced diet will certainly help a lot. Having more fresh fruit and
vegetables every day are good for you. Which you know, a proper method of learning will
enable you to learn more and faster. To get better results, that is wise to be attentive and make
every effort to gain knowledge. And you were supposed to review your notes taking down after
class every day. Always remember to stay happily and optimistic so that you can be energetic
while doing the revision. I hope you’ll no longer feel tired and nervous.
Best wishes.
Yours,

答案：
(答案→)advices→advice
解析：本文写的是因为Jenny在大学入学考试前非常紧张，作者给出的几条建议。
【小题1】因为advice 建议是不可数名词，所以没有复数形式，所以去掉s.
【小题2】固定短语prepare for 为。。。。。。做准备，所以加for.
【小题3】固定用法：however +many + 复数名词/however + much + 不可数名词+ 主语 + 谓语，无论多少…… ,所以把whatever 改成however.
【小题4】固定短语:on occasion 有时候，所以去掉an.
【小题5】因为句子主语Having more fresh fruit and vegetables是动名词做主语谓语动词用单数，所以are改成is。
【小题6】词句是一个非限制性定语从句，which引导非限制性定语从句不能位于句首，所以改成as.
【小题7】本句真正主语是to be attentive and make every effort to gain knowledge，应该由it做形式主语代替真正主语不定式短语，所以that改成it。
【小题8】此处是时态错误，整个短文都是现在时态，本句也不表过去情况，所以were改成are。
【小题9】非谓语错误。notes 和take 之间是被动关系做笔记倒过来笔记被做，所以改成taken,
【小题10】副词错误。此句中stay 是系动词后面应该跟形容词构成系表结构即保持快乐和乐观，所以happily 改成happy.
