二、聚焦高频考点

如果是父母作主，把女儿“嫁”出去，也用marry，如：
She married all her daughters.

2.occur, happen, take place都含“发生”的意思。
happen为常用词语, 指“一切客观事物或情况的偶然或未能预见地发生”，如：

happen to sb./sth.指不好的事情发生在某人(物)身上
occur属正式用语, 指“按计划使某事或效果发生”，通常所指的时间和事件都比较确定，在以具体事物,事件作主语时，可与happen 互换，如：

occur to sb./sth.指“某种思想等呈现于某人的知觉中”，如：
Didn't it occur to you to phone him about it?
