谁帮我看看这个英语句子有没有语法错误，谢谢了

Question

First of all, what I don't want to say so much, he is a assiduous student and has a good record.

Answer 1

有语法错误，what I don't want to say so much 是一个主语从句，he 也是一个主语，一个句子中有两个主语是不对的，a assiduous 应作 an assiduous。
看这个句子，不知道 what I don't want to say so much 是不是“不用我说太多”的意思，如果是，那么应在后面加上：is that，即：
First of all, what I don't want to say too much is that he is an assiduous student and has a good record.
以上就没有语法错误了，但要更地道的英语应再加修改：
First of all, he is, needless to say, an assiduous student with a good record.

Answer 2

1） First of all,（对，没有问题）；
2） what I don't want to say so much（对，没有问题。在整句做主语从句）；
3） he is a assiduous student and has a good record. （‘he ...’应当是这里应当是表语从句，在其前加‘is that’引出从句）；
4） 全句为：First of all, what I don't want to say so much is that he is a assiduous student and has a good record.这样构成了：what做主语从句＋系词（is）＋that表语从句。整个为主＋系＋表句型。

Answer 3

有语法错误。可以改成：
First of all, what I don't want to say so much is, he is a assiduous student and has a good record.
用what 引起的应该是主语从句，后面缺了谓语is

Answer 4

不能说有语法问题，因为我们中文平时说话也多多少少会有语法问题。
这句话的关键问题是听起来有些弱智~~
我不想说太多~ 然后还是把话给说了，就多多少少有些弱智了，
first, what I don't want to say so much.
翻译成中文就是：“首先，我不想说的是说非常那么多”。。。狗屁不通的。
可能要表达的意思是first, I don't want to say too much吧。我不想说太多。还有对assidous不知道是不是能这么用，可能用workhard strudent或者 diligent好一点。

Answer 5

what I don't want to say so much 你是想表达我不想说太多的是......对不对？
so much改成too much会好点，另外
what I don't want to say too much后面要加个is

Answer 6

First of all,What I don't want to talk about so much is that he is a assiduous student and has a good record.强调句的疑问句的应用，is 是系动词，that引导表语从句，这样改后句意更明确，结构更清晰！（个人观点，供参考！)
