3用词搭配不当。英语语言的一大特点是其丰富的习惯用语和固定搭配,包括动词短语,介词短语,形容词短语,例如(花费很多时间做某事)"spend much time in..."不能改成"take much time in..."。词与词之间的固定搭配是由历史形成的,有的看起来不符合逻辑,但却是地道用法。
People learn English to use it. Some learn it to study or work abroad. Others learn it to read books and magazines in English or have something to do with English-speaking foreigners.
采用适当关联词,改进为:People learn English for practical purposes: some learn to study or work abroad while others learn to read or communicate in English.
