Not until thendidtheyrealizethat their son wasaddictedtocomputer games and often skipped school．

Answer 1

分析 直到那时他们才意识到他们的儿子沉溺于电脑游戏且时常逃学．

解答 答案：did； realize； addicted to 考查句型转换．原句是强调句，同义句则是倒装句，not until放在句首时要用倒装句，还有：have addiction to与be addicted to意为相同．

点评 同义句型转换，是把意思相同或相近的句子用不同的词汇、短语及句型表示出来．同义句的相互转换除了考查主动句与被动句，复合句与简单句之间的转换，直接引语变间接引语外，还有一些词或短语的替换，仅仅通过替换几个词或短语，而使句子意思不变，就能达到异曲同工之妙．"句型转换"题是用来考查学生对句子结构变化所掌握的程度．
