Question

请帮我修改一下语法上的错误，谢谢您

With the traditional way of structural optimization design to achieve weight reduction has reached the bottleneck, and carbon fiber reinforced composite (CFRP) with light weight, high specific strength, corrosion resistance, impact resistance and other characteristics has become one of the substitutes for metal materials, is gradually applied to all walks of life. Porous composite components are widely used in mechanical connections, but the application of this new material and new structure also brings new challenges. In this paper, the research significance and current situation of failure mode and progressive damage of CFRP with holes are introduced. The stress-strain mathematical model of the hole in the loading process is established based on the complex function by using the finite element simulation software ABAQUS, and the tensile and compressive failure process of composite laminates is modeled by using the finite element simulation. On this basis, the strength change and damage of the material in the loading process of CFRP with holes are analyzed The damage propagation behavior is studied and analyzed, the progressive damage behavior of CFRP plate is explored, and the damage mechanism of the area around the hole is revealed. This study is helpful to clarify the damage mode of CFRP under load and provide the theoretical basis for the reliable service of composite components.

Answer 1

第一句，状语从句后面的主句缺少主语，即XXX is gradually…life.
第二句，通常会改成两句，即connections后面会是句号，并将but首字母大写。
第三句，句子明显头重脚轻，建议改成：Introduced first in this paper are the….（此处first与第四句加的later on呼应）。
第四句句首建议加上Later on，即：Later on, the stress-strain…simulation.
第五句，第一个analysed后面加上逗号，且后面的The首字母小写，以便和后面整体构成并列句。
最后一句，首个单词改成The.
注：从写作内容上可见题主的英语功力深厚。但作为论文摘要，建议尽量避免使用结构过于复杂的复合句，同时要注意句子之间过渡语的使用，这样可以使写出的东西更简洁明快、流利上口。
个人拙见，未必合适，仅供参考。

追答

第一句的首单词改成As会更好

第一句逗号后面也可能是缺少了连词and

Answer 2

nothing除了可以是不定代词外，还可以是副词，表示否定。本句中like me为介词短语作表语，nothing否定副词，否定like me. (如果是something在句子也是副词。)
