1.As接一个从句,表示因为、正如的意思,逗号后面是主句.其他的选项不能接从句.
2.it代表前面一句所说的事,其他选项不具这个功能,it放在这也是固定用法.
3.首先用it代表这个老师,排除后俩选项,接着A选项不应该接that,所以选B.另外因为问句里是过去时态,所以回答时不能是现在时,而要用完成时.
4.force固定用法,请查字典.
5.anxious about sb.担心某人
anxious for sth.渴望某事.
6.many people 排除c,d选项.b表示花种类多
7.首先要接从句,用a.b.c,d意思不对,没有当...这个含义.
接从句,不定式代表将来时,进行时代表过去时,和主句时态一样.

1.一个句子只有一个主语，其他三个选项如果填的话，就有两个主语了，又没有连词，AS在这里引导后面的部分做状语
2.很明显，IT做代词，一般遇到这种没有语境情况的选IT没错
3.问句是过去时态，排除A,C。这里it代指一件事
4.......不太清楚，估计是固定搭配
5.固定搭配
6.公园里的花是种类多，而不是足够的，所以A错，a great diversit...

5.固定搭配
6.公园里的花是种类多，而不是足够的，所以A错，a great diversity of +N.固定搭配，表示种类繁多；many a + n.是可数名词
7.现在分词做状语，表示同时
一年多没碰语法了，不太会了，可能有的解释不对吧
建议还是不懂问老师的好，不过语法真的很麻烦

1.B肯定不对，因为是it has already been pointed out that +从句，而题中有逗号，CD就当然不对啦，that,this不接从句。而A，as 后加从句，主语可省略，例如as a child,i used to climb the trees.前面的从句=as i was a child.
2.it 是代表Tom生病这件事
3.过去时，所以AC都不对...

2.it 是代表Tom生病这件事
3.过去时，所以AC都不对，因为这个人不知道是谁，连性别也不知，所以用it.如果改为was the man our new teacher...?就用he must have been.
4.因为语境作为前提。he makes his way 都可以，CD都不对。
5.anxious about sth为顾虑担心某事物，anxious for=eager for,表示盼望，渴望。
6.plenty表示大量的意思，diversity表示种类多，因为连词是and，前后要一致地表示多，而不应该用a few.
7.排除D，因为前面是I，后面是We,感觉就已经很不对，B不对，to表示目的，逻辑关系不对，Cwhile是表示动作的同时发生，前后事态要一致，一般为前后都为进行时。句子头个动词为ing形式，可以表示从句。
