请有心回答的人给出每题的详细解释,要有中文翻译,语法点讲解
缺一不可,既然有心回答就请尽量的做好来,谢谢大家

1, is being表示将来进行时,但句子的意思土壤流失每年都在流失,以前,现在,都是这种情况,所以要用现在进行时表一段时期的持续情况
2.中间along with his assistans是插入语成分,主语是Professof smith,要有谓语,也就是is working, 你的working, 分词不能单独做谓语
3.表转折,而不是因果
4.remain 动词,表示"保持,仍然是",相对于主语progress来说是主动关系,
过程仍然还怎么样
5.be doing 是进行时态,此时此刻在做某事,或现阶段做的事情
be to do 是将来时,指计划好的即将要发生的动作
6.物做主语,要用被动,intend表示意图,想要做某事,发出者是人

不懂

1.首先这个题就不是过去式,开始的 being destroyed 用的是被动.然后是后半部分huge quantites of good earth .注意了是复数形式所以答案应该用are.并且用到被动."被冲走".
2.注意中间的along with his assistants 是个插入语,在做题的时候完全没必要看它(个人看法).smith博士一直在夜以继日的做这个项目为了在限期前完成.(大概就这个意思)用-ing是因为这里想表示一个"一直"的意思.
3.考查语感.我希望你不会介意我提问,你的鞋子在哪买的?句子很简单大家都晓得意思,但是考的就是一个语感,没什么好讲的也.自己多积累就行.
4.我认为两个答案都说的同样,嘿嘿
5.be to do sth该做什么事.你用is handing out也解释不了啊.不可能是他正在对那些天才学生提出表扬吧.原句的意思是:"无论是你还是班长都不该在会议上提出对那些天才学生提出表扬."
6.老问题.被动语态.

1 quantites 这里是复数,必然要用are
2 把，along with his assistants，放到句尾，自然就看出Professof smith才是主语
3没什么好说的，固定用法
