以上为一些英语单选题是本人错的,麻烦帮忙写详细错误理由,越详细越清楚越好,最好也有些知识的延伸,但是不要太长篇大论啦.如果回答的好追加20分.感激不尽~~~晨式鞠躬^^

1.put sb.s head together.大家一起动脑筋想问题.
2.主动可以表示被动的含义.表示物体的属性不用被动.
3.后接father所以要用定语whose,而不是who.
4.enough的否定式：be +not+形容词+enough.肯定式为去掉not.
5.用现在式表将来.且要用被动词态.
6.例句为the +形容词比较级+……,the +形容词比较级+……的格式,跟据题意,应该是我们浪费或污染水越多,则明天我们拥有的水越少.more,much（多的）的比较级.less是little（少的）的比较级.
7.as +形容词原极+as ,意为像（和）……一样.
8.how to do sth,词组,表示怎么（如何）做某事.接在do you know 后必须是一个完整的句子.
9.句式：I think it（名词） +to +宾语.表示我认为……怎么样,如何.
希希望对你有所帮助,学英语需要记住一些常用的句式和常用词组.
