雅思中从句连接词要省略吗？
不用，连词是可以有且只有一个的。 不过雅思作文要求相对宽松，如果你时间足够充裕的话，建议把所有可能用到的连接词都写上，这样在修改时就不必花时间去思考到底哪个更合适了；如果时间不够，那就只写一个表示顺承关系的连接词（只有一两个字）。但请注意主句和从句的主谓一致！还有，即使使用了连词，句子仍然是独立的，不可以有标点符号。 举几个例子说明一下：
1. I know that the bus is late because it has been delayed by traffic jams. 原因状语从句引导词that可以省略。
2. I like to cook with my friends on weekend afternoons，when we can relax and chat while preparing a delicious meal. 定语从句引导词when不能省。
3. My father told me not to be late for school again as he was busy at work yesterday. 目的状语从句引导词that可以省略。 (注意这里as引导的状语从句修饰整个句子，而不是修饰前面的句子。)
4. The government should implement strict laws and policies to reduce the number of road accidents in order to keep our society safe. 目的状语从句引导词to可省略。
5. We will go hiking this afternoon if there are no changes in the weather forecast. 条件状语从句引导词if不可省。
6. There were two reasons why he did not finish his homework on time. 原因状语从句引导词why不能省。 自己练习的时候尽量养成习惯，不要自行省略不需要的连接词或添加不必要的连词。这样可以避免语法错误，也方便老师修改！
