Question

1．孩子们不敢站起来除非爸妈要求他们这样做．（dare，unless）The children don't dare to stand up unless their parents ask them to．．

Answer 1

分析 The children don't dare to stand up unless their parents ask them to．

解答 The children don't dare to stand up unless their parents ask them to．
这是表达的对人们的一种评价，所以使用一般现在时．
当dare用作实意动词时，用dare to do sth表示敢于做某事；unless引导一个条件状语从句．
当dare用作情态动词时，则dare后面直接跟动词原形，即The children  dare not stand up unless their parents ask them to．

点评 适当运用主从复合句，并能够灵活运用复杂句式来表达句子的意思有助于学生翻译能力的提高．
