句型结构
肯定句:主语 + was/were + V-ing + 其他

否定句: 主语 + was/were + not + V-ing

Was/Were + 主语 + V-ing
回答：Yes, 主语+was/were. No, 主语+wasn’t/weren’t.

特殊疑问句:疑问词 + was/were + 主语 + V-ing

动词ing形式变化规则
一般情况 直接加ing
read-reading play-playing eat- eating
以不发音e结尾 去e加ing
Write-writing dance-dancing live- living
以重读闭音节结尾 双写尾字母加ing run running
run-running swim-swimming sit-sitting
以ie结尾 变ie为y加ing
Lie-lying die-dying tie-tying
以元音+e结尾 直接加ing

双写规则判断（判断是否需要双写）：
get → getting (重读闭音节)
open → opening (非重读)
listen → listening (结尾不是单辅音)
begin → beginning (重音在gin，双写n)
