his writing was so confusing that it's difficult to make out__it is he is

His writing is so confusing that it's difficult to make out___what__it is be is trying to express.~

这个复合句里有一个so...that引导的结果状语从句，结果状语从句里还套着一句疑问代词what引导的宾语从句。这句话的意思是：“他的字迹很潦草，很难辨别出他要表达什么。”希望我能帮助你解疑释惑。

你确定是两个空吗？第一个应该填what，是what引导的宾语从句。要是有第二个空，那就是that吧。

33.His writing is so confusing that it’s difficult to make out _____it is he is trying to express.
A. that B. how C. who D. what
答案：D. what
句子结构分析：
第一层：这是一个含有由that引导的结果状语从句的主从复合句。
His writing is so confusing that it’s difficult to make out what it is he is trying to express.
S L P A Cl.（结果）
第二层：结果状语从句的结构是：
that it ’ s difficult to make out what it is he is trying to express
引导词 S(f) L P S(r)
第三层：在真正的主语中，有一个由what引导的宾语从句。其结构式是：
to make out what it is he is trying to express
to do O Cl.
第四层：在what引导的宾语从句中，有一个强调句式it is ... that...，只是that被省略了。
what it is he is trying to express
= what it is that he is trying to express
= it is what that he is trying to express(被强调部分是宾语what)
分析成分时，我们把强调句式it is ... that...这三个字拿掉，就成了：
what he is trying to express
what 是因为起引导作用而被提前了，还原其位置应该是：he is trying to express what
分析： he is trying to express what
S V O
在宾语中， to express what
中心词 O
这里关键是：强调句式中的that能不能省略的问题。我说可以省略的依据是：
《大学英语语法 第四版》(徐广联主编；华东理工大学出版社)PP. 903-904上有讲解和例句，现摘录几个共享：
1. It is me (that / whom) she gave the book to.
2. It is fame (that) he is seeking.
3. Who is it (that) you want to see?
4. Where was it (that) you saw the man?
整句译文：他写的东西很乱，很难弄明白想表达啥。
好了，就回答到这里，不知能不能让你满意，有疑惑我们可以继续探讨。另外，由于百度这里的文字格式输入的限制，我没有办法给你画出整个句子的结构图，望谅解。

what。句子没问题，是what引导的从句和定语从句相结合

what,因为he is缺少句子成份，what能代替没能表达出的成份，what he is.

his writing was so confusing that it's difficult to make out__it is he is 这句子有问题啊，结尾处怎么又it is 又he is的？请问原句是什么？

what
express加宾语，what 后面是宾语从句

盍姣培元： 首先问你知道that,那为什么which不可以用呢?两个都是可以修饰名词性从句的. 所以就可以见with在这里是有用处的,writing,那句子中指出是用什么写呢?用铅笔写,所以with在这里实际上翻译我们汉语中的“用”字. 所以,这个句子是with引导的一个方式状语从句,明白了吗?
