应对

　　Some people think that secondary school students should study international news as a school subject but others argue that it would be a waste of valuable school time.

　　Discuss both views and give your own opinion.

　　这个题目

　　学生在开头段落的第 一句写了下面这句话：

　　Some people consider it necessary to make learning global news as a senior high school subject, while their opponents regard it as a waste of school time.

　　我们来看教师修改后的句子，如下：

　　Learning global news may be a worthwhile subject at secondary school; it may also be a waste of time.

　　 首先，是句子的简化。抛弃陈词滥调的无聊的some people … their opponent … 而更直接的说出了内容。

　　原句中的consider it necessary to make learning global news as a senior high school subject和 regard it as a waste of school time都是繁琐的方式。改动后，be a worthwhile subject at secondary school和be a waste of time中用了be动词，在措辞上简化，让句子读起来更顺畅。这里特别注意这里用的是情态动词may，这样，“may be”就避免了去主观认定一种情况为事实，而是语气缓和地说了一种可能。

　　分号“;”替代了while，比起用while来联系两个分句，分号使得两个分句形更工整的结构。这里并不是对于错误的纠正，因为while的用法无误。这里只是故意用到特殊的标点符号来追求这个句子的节奏上的风格。

　　小总结

　　好句子是在形式上最求最简的形式，避免措辞上不必要的部分(长句子不是刻意追求形式上的长，而是出于内容的需要而长)。
