Answer 1

答案：
解析：

　　1．去掉a　由下一句“The lake is polluted”，看出湖水遭受污染，几乎没有鸟、动物和鱼。few表示否定。

　　2．is后加in　be in a color of…，“处于某种颜色的状态”，此句为“湖水呈现深黑的棕色”。

　　3．it→we　由上文看出湖水污染严重，我们必须弄清楚水是怎样进入湖的。

　　4．Unless→When　当下雨的时候，雨水从周边地区进入湖里。unless“如果不……”，不符合。

　　5．are→were　由In the past看出，此句应该用一般过去时态。

　　6．√

　　7．forests→lake　由“In the past，there were forests all around Lake Ponkapog”，看出Now there are many homes around the lake．

　　8．去掉for　“他们在室内用其他的化学药品”，for是多余的，应去掉。

　　9．neither→also　还有很多商家也用化学药品。

　　10．Another→Other　other为形容词，此处泛指其他的东西，后接复数名词。another“三者之中的另一个”。
