帮忙分析分析语法

Answer 1

1. There being no cause for alarm(这种结构称为独立主格结构,一般充当状语，there被当作了逻辑主语）
相当于Because there was no cause for alarm
如：
Weather permitting（=If weather permits), I will go out.
There being many students in the classroom, the teacher began his lesson.
2. 现在进行时的被动语态：
The flag is being raised now. 正在升旗。（旗正在被升上去）
B C rise不及物动词，没有被动
D 及物的。应该用被动
用rising就对了。

Answer 2

第一个句子选D:There being no cause for alarm ,它是个独立主格结构做原因状语他there being 是there be 的现在分词形式，后面的 no cause for alarm 是这个结构的逻辑主语，句意为：
因为没有理由按响警报，这人又回到床上睡下了。
第二个句子选A：The flag is being raised ."is being raised"这个谓语动词是一般现在时的被动语态,也叫被动语态的一般现在时,being 是助动词.句意: 典礼已经开始了,正在升旗.

Answer 3

1,因为这是一句话，只能有一个谓语，而后半句已经有谓语动词了，所以前面就要用非谓语动词把there was 变成 there being .
2.首先排除B.C选项，因为rise是不及物动词，无被动态。而旗子是正在被升起，所以必须用正在进行时的被动语态，用being done的形式
