4-1 （With the view of practicing my English, I give the answer in both English and Chinese. ) As was said by the pal from Niger, who gave a comment above, it's true that you're not to blame. Just look at the notes at italki.com made by the EngIish speakers who're learning Chinese: there're so many mistakes or within. We're in the same situation as them. ------------------------------------------ 正如尼日尔的那位哥说的，这不能怪你。看看italki.com上那些说英语的人写的笔记吧，里面错误多多。我们的情况与此相似。 But what is different is that a considerable portion of them will have a rather good command of Chinese after a certain term of learning, just like their antecessors, that is, they will acquire the capabilities of general speech, writing, listening and reading comprehension. ---------------------------------------- 但是不同的是，他们当中有相当一部分人经过一段时间段学习以后，会掌握一般的听说读写的能力。他们那些学汉语的前辈也是这样。 As a matter of fact, many of our antecessors who had studied in the missionary schools before the PRC achieved a pretty high level in foreign languages, such as English, French and German. They spoke and wrote very smoothly in certain foreign languages. The parallel condition is continuously maintained in lots of countries such as India and quite some European states. ------------------------------------- 实际上我们那些解放前在大学里学习的先辈们中很多人外语达到了相当高的水平，可以用外语流利地说写。今天像印度和好些欧洲国家情况还是这样。
