Answer 1

1.因为不知道是男的还是女的，用It来指代，就好像有人敲门的时候，会问 who is it? 谁啊？
然后who was it就是典型的特殊疑问句的顺序 后面的that引导的从句是修饰it的。

2. 有个for months，表示一段时间，用现在完成时have struggled for +一段时间，然后having struggled ..... 这里是ing形式，也就是现在分词形式来作状语

3.sb. is believed to have done sth. 某人被认为已经做了某事
她肯定是错过了那车了，要不然她可能都回到家了现在。

4. 主句是后面的 we are doing...... 那么前面的to explore the question是不定式来表示目的，为了.......

Answer 2

1. ( )-----that accompanied the homeless beggar to the hospital? 选D
Awho it was B who he was C who was he Dwho was it -----强调句
2.( )MY sister, -----for months to find a job as a teacher,finally took a position in Wenzhou Daily. A struggling B struggled C to struggle D having struggled 选D-------分词结构，分词结构做时间状语
3.She is believed -----the train,otherwise she would have arrived here by now?
Ato miss B to have missed C to be missed D to be missing 选B-----------B 做主语补足语
4.（）-------the question of how global warming has ---,we are doing some projects at school.A Exploring ,come about B To explore,come out CHaving explored ,come to DBeing explored ,come over .选B--------你这一句写得有问题，核对一下

Answer 3

1.D
Was it Jim that told us the news?（强调句型的一般疑问句形式）,一般疑问句，只需把be提前。
Who was it that told us the news?（强调句型的特殊疑问句形式）,只需在一般疑问句前加上疑问词。
不清楚是男的还是女的，所以是it。
2.D
现在现在分词的完成形式作状语,表示这动作在谓语所表示的动作之前发生。
3.B
miss动作发生在believe之前，所以用完成时。类似用法还有be said to 等。
4.我认为应该选A
现在分词做状语，表示目的。come about 产生。
为了探索全球变暖是如何产生的，我们正在在学校做一些项目。

Answer 4

第一个是 it is that 的强调句的在疑问句的应用。。。 可以把他去掉。。变成who accompanied.......
第二个是 句子已经有它的谓语fianlly took a ......... 所以此空填的是非谓语形式，，，，时态为完成时 因为是 for months
第四个 to explore 是表目的 为了探究全球气候变暖是如何产生的，，，我们在校开展了一些实验。。。。。
understand？？？？

Answer 5

1、选D吧 首先，不知道人称的用it 然后这是强调句，并且是一般疑问句，要到装
2、选D。真正的宾语是took，所以struggle是非谓语动词，且是主动地（没有被挣扎吧）。再看，后文有finally，并且前后两句是有关联的，所以要用完成时。
3、B Be believed to是固定的，再看时态，后文是would have，是对过去时的虚拟，所以这里也要用过去式或完成时
4、A came about产生，出现。这里也是非谓语动词
