1.A
A项作WONDERING的宾语,所以要用陈述语气.C就不对了,被排除.又,这是个强调句型.你把他还原开来,就是 it was where that I first met him.用"It was ...that."这种强调句型强调地点(此处是强调代指地点的代词where)所以B`D不对.至于为什么用where呢?据题意可知,"我想知道我第一次在哪见的他".where在句中代指我第一次见他的地点.
2.A
A项"增加"的意思
B项"增加到"eg:人数增加到了1000.
C项"总计"eg:人数总计为20人.
D项"被增加到"
根据这句话的意思:这场糟糕的暴风雪增加了我们建筑工程的困难.易知,缺空处应为"增加"的意思吧?
改错
1.把"have for years studied the weather "改为"had for years studied the weather"吧?因为后面"managed to make weather forecasts.
"的意思为"设法成功做到了天气预测".而句子时态还为过去式呢.那前面说"所有国家的人们都努力研究天气好几年"不就是过去的过去,应该用过去完成时了吗?
2.这句话意思为"我很高兴知道每个人在家都像平常一样享受着健康."其中"像平常一样"应该为词组"as usual".而且也没"as usually"这个词组.所以把as usually改为as usual.
这样说是不是够详细了呢?

A 后得用定语从句，倒装语序
B add的基本用法
People in all countries have studied the weather for years and managed to make weather forecasts.
现在完成时
第二题不确定，应该是I am glad to know that everyone is enjoying good health at home as usually.

A
A
People in all countries have studied the weather for years and managed to make weather forecasts.
I am glad to know that everyone at home is enjoying good health as usual。

A陈述句形式
A增加
studied-studying
usually-usual
