Copper sulfate, spread in judicious amounts, kills algae
does not harm
fish or aquatic invertebrates.
选项
A、but does no harm
B、without harming
C、except harming
D、but not harming
答案
B
解析
句意:适量的硫酸铜可以杀死藻类,而不会伤害鱼类或水生无脊椎动物。本题可采用排除法。harm作名词时,常用结构为do harm to,而A选项中缺少to,因此排除A选项。C选项中except表示“除了”,相当于apart from,用在此处不合句意。D选项应改为but doesn’t harm。所以选项B为答案。
