英语里逗号之后跟的是什么?
A moderate earthquake struck parts of southeast England on 28 April 2007,toppling chimneys from houses and rousing residents from their beds.
1.逗号后面的句子toppling chimneys from houses and rousing residents from their beds是状语吗?
2.是倒桩句吗?
3.several thousand people有这种说话吗?thousand后面不加s吗?

1 是伴随状语 说明 topple 和rouse这两动作和主句的谓语struck是同时伴随发生的.
2 不是倒装,
3 引用另外一位百度知道的答案
several thousand 作前置定语用时(后面有其它名词)按规则一般不加s 例如:
Several thousand lawyers suspended for failing to pay dues
引自:加利福尼亚司法报
Wireless carrier Sprint Nextel Corp plans to lay off several thousand employees,
引自:路透社报道
但这点并不严格,也有例外,例如:
Several thousands pilgrims travel to Pleine du Nord,Haiti for the annual festival of Saint Jacques.
UNiFEED 联合国广播网站
Several thousands demonstrators protest on June 1,2008 against opening of a new rubbish dump
今日美国新闻网站
但所表示的基本意思都一样.
做单独名词使用就需要加上s
例如:
We have sold several thousands of Mobile Cell Phone
Several thousands were killed and thousands more injured as a strong quake measuring 6.3 on the Richter ...
Several thousands of Ingush protesters in the streets of Nazran ...
总体来说,英语在这方面不是很严格,所以引起老师们的分歧.实践中,没有那么抠语法的.
但在考试中,记住做前置定语用时不加s,其余都加就可以了.
