How do you learn English ？

ow do you learn English ？ We learn new words ----reading papers and magazines A，题里加s了.by B.through C.from理由,请问by后面加的是没有任何修饰的词

因为在表示手段的时候,我们一般情况下是不用though的;
但是我个人觉得C项也说的过去!我个人觉得这道题目的最佳答案应该是A项你好,因为by是表示某人通过一种什么样的手段,可以这样翻译:我们学习的新单词是来自阅读报纸和杂志;
当然,B项是肯定不对的,很符合题目的意思[我们学习的新单词是通过阅读报纸和杂志的]

to learn a foreign language well is not easy.i try my best to find some ways to learn english.firstly,is reading aloud.we know that reading can improve our pronunciation and we can read at any moments.secondly,is listening.we can spend only half an hour listening the video .thirdly,is speaking.we know that spoken english is very important.so we can practice coverstations with partners.lastly,is writing.we must write in english everyday.though only some scentences and some words.that's all ways i have done.

A.by from是肯定不选的，意为“从……中（来）” B选项是不对的 by与through这两者都有通过的意思,by意思是通过,利用,应用在实物上,强调的是某件事情的主要作用者或主要方式 比如:I always go to school by bus. 而through是用在比较抽象的东西上,而且它的通过之意是表示从中间通过,穿过,强调的是某件事情的过程和地点。如:Through the window I saw the beautiful garden

A 我们通过阅读报纸和杂志的方式来学英语。 By doing sth 通过做...的方式
