Recently, I have came across an article about the importance of reading. It said that reading can help us to expand our knowledge and increase our vocabulary. However, I find that I have difficulties in read books, because there are always some new words and phrases that I don't understand. This makes me feel frustrating and I often give up easily. In addition, I also have problems in writing. I often make mistakes in grammar and spelling, which make my writing look unprofessional. I know that I need to improve my English, but I don't know how to start.
解析：
1.錯(cuò)誤：I have came across
改正：I have come across
解析：come across是固定短語(yǔ)，表示“偶然遇到”，不需要加助動(dòng)詞have的過(guò)去分詞形式。
2.錯(cuò)誤：in read books
改正：in reading books
解析：have difficulties in doing sth. 是固定句型，表示“在做某事上有困難”，所以需要用動(dòng)名詞形式reading。
3.錯(cuò)誤：This makes me feel frustrating
改正：This makes me feel frustrated
解析：frustrating是形容詞，通常用來(lái)描述事物令人沮喪的特性，而frustrated是形容詞，用來(lái)描述人的感受，即“感到沮喪的”。
4.錯(cuò)誤：give up easily
改正：give up easily
解析：雖然這個(gè)短語(yǔ)本身沒(méi)有語(yǔ)法錯(cuò)誤，但在上下文中，為了表達(dá)更強(qiáng)烈的情感，可以在easily前加上too，即give up too easily，表示“太容易放棄了”。
5.錯(cuò)誤：which make
改正：which makes
解析：這句話的主語(yǔ)是前面的整個(gè)句子（I often make mistakes in grammar and spelling），作為單數(shù)概念，所以后面的動(dòng)詞要用單數(shù)形式makes。
6.錯(cuò)誤：my writing look unprofessional
改正：my writing looks unprofessional
解析：整句話的主語(yǔ)是my writing，作為單數(shù)概念，所以動(dòng)詞要用單數(shù)形式looks。
7.錯(cuò)誤：need to improve my English
改正：need to improve my English（此句無(wú)錯(cuò)誤，但可添加細(xì)節(jié)）
解析：雖然此句本身沒(méi)有語(yǔ)法錯(cuò)誤，但為了表達(dá)更具體的改進(jìn)方向，可以添加一些細(xì)節(jié)，如“need to improve my English in both reading and writing”。
8.錯(cuò)誤：but I don't know how to start
改正：but I don't know where to start
解析：在這個(gè)語(yǔ)境中，使用“where”比“how”更合適，因?yàn)樽髡呤窃趯ふ乙粋€(gè)開(kāi)始的地方或方法，而不是一個(gè)過(guò)程或步驟。
