a busily preparing
b busy preparing 选哪个？选b的话students后没有be动词呀？是不是省略了
who are为什么可以省略？不是关系代词在从句中作宾语时才可以省略吗

Answer 1

a

1st.

u should get de point : <busily preparing> OR< busy preparing>
is used 2 tell u more about de students in de SR.

2nd.

so we change it in2 a sentence: de students r preparing 4 de exam busily.

3rd.

as we all know de main part of de whole is:de LSR is full of students.

subjection:LSR

verb(B verb):is

objection: students

adj:full

See, de sentence is finished,so" r preparing busily "should b changed
in2 a form just like an "adj"

4th.

prepare is a verb, student s ACT OUT "prepare" (students-->prepare) not students B "prepared"

so we use "ing"form

5th

but" preparing" is used like a verb `s fuction ,so we choose ADV 2

decorate verb-->it is "busily"

eventually

de answer is B

我用英语解释的原因哦，读读看，一点都不难！
其实英语答题贵在拥有英语思维而非懂得深奥的语法。
当你能用自己的语言解释清一个抽象的问题时，知识才是你自己的，想忘都忘不了了。
死记硬背是很坑人的！血和泪的教训啊～

Answer 2

前面的 The library's study room is full of students 整个当成是主语啊
preparing 是动词啊（谓语） 就是谓语啊 busily 副词啊
选A 啊
be动词 也就是谓语啊
这里也不需要用从句啊

Answer 3

都对
A
preparing for the exam 作 students 的伴随状语，
busily 是副词，修饰 preparing (准备）是“忙碌的”
B
当定语从句中出现“who" "which"等 作主语，且后跟系动词时，
主语与系动词可直接一起省略

可是A也可理解成省略who are 的进行时态的句子啊！？
还是去问老师吧

Answer 4

没有看见选项

who are引导从句的时候不省略
但是这个地方不是一个主语从句
是用后面的preparing做伴随状语来形容students

Answer 5

busy preparing
该句子省略了who are
完整的是
The library's study room is full of students who are busy preparing for the exam.

Answer 6

觉得楼上解释得很有道理，我也都被弄晕了，有答案时发下，嘿嘿~
