i suggest you buy some flowers for her. 这有没有语法错误
Dear Mark,
Thank you very much for your letter. In your letter, you said you would spend a few days to travel in China and asked me to plan a route for me. This is the plan that I suggest for you:
You will start your trip from Beijing and your destination will be Hainan, the southern part of China. The duration of this trip will be five days and four nights and will cost around 8000 yuan. On the first day, you will fly to Sanya & spend the night in sanya hotel. On the second & third day, you will go to dadomghai beach & yalongwan and relax on the beach and swim in the sea. On the fourth day, you will travel by bus to haikou and you can go shopping there and buy some souvenirs. On the fifth day, you will return to Beijing.
Looking forward to seeing you soon.
Yours,
XXX
书信格式都齐备了
请您参考suggest的用法：
1. suggest+ 名词/代词 （或suggest+名词/代词 ） to+人，但不能说suggest sb sth ,即不能加双宾做宾语
Eg：We suggest him the plan (Χ)
We suggest the plan to him(√)
2. suggest+doing sth
Eg： He suggested going out for a walk.
注意：suggest 不可以加不定式，所以上面的句子不可以这样写：
He suggested to go out for a walk.(Χ)
3. suggest +(that )+主语+(should) do+sth 其中的should 可以省略
eg: He suggested that you should go there tomorrow.
=He suggested you go there tomorrow.，你问的例句就是如此。
注意： suggest 不可以加不定式的复合结构
He suggested you to go there tomorrow. X
4. it is suggested that +主语+(should )do sth
eg: It is suggested that the work (should) be finished at once.
5. suggestion做主语时，其后的表语从句也用这个结构即：
The suggestion is that +主语+should +do sth
eg: His suggestion is that I should leave for Beijing immediately.
6.suggest 表示“暗示或表明”之意，注意此时做主语时后面的表语从句用陈述语气
eg: Her yawn suggested that she was sleepy.
她哈欠连天表明她困了。
几个同义词的用法比较
一、有“建议”的意思。advise、propose也有此意，请比较它们用法的异同：
1)都可接名词做宾语
She suggested/advised/proposed an early start.她建议早一点出发。
We suggested/advised/proposed a visit to the museum the next day.我们建议明天去参观博物馆。
2)都可接动名词做宾语
I suggested/advised/proposed putting off the sports meet.我建议将运动会延期。
They suggested/advised/proposed waiting until the proper time.他们建议(我们)等到恰当的时机才行动。
3)都可接that宾语从句，that从句用should+动词原形，should可以省略。
She suggested/advised/proposed that the class meeting (should) not be held on Saturday.她建议班会不要在星期六举行。
We suggested/advised/proposed that he (should) go and make an apology to his teacher.我们建议他去向老师道歉。
4)advise可接动词不定式复合宾语，propose可接不定式做宾语。
没有，你的suggest后面加的是句子，suggest doing 没有sb.还有这个词的虚拟语气要注意！
没错。这句话可以看成I suggest (that) you (should) buy some flowers for her. should that 都省略。
行，
还可以用：
I'd advise you to buy some flowers for her.---这句话的语气婉转一点
I'd suggest that you buy some flowers for her.---这句话的语气婉转一点
I suggest that you go buy some flowers for her.---这句话的语气婉转一点， 使用that会使句子更加完整。
I think that you should go and buy some flowers for her.
My best suggestion is to go and buy some flowers for her.---这句话比较正式，因为里面的subject 是“my best suggestion" 而不是 ”I"
