Question

—We should _______ humans from ________ down too many trees. 
—I agree with you. Trees are very important to us.              

A．keep; cut

B．prevent; cut

C．stop; cut

D．prevent; cutting

Answer 1

D

试题分析：keep保持，坚持；prevent阻止；stop阻止。句意：我们应该阻止人们砍伐太多的树木、——我同意你的看法。树木对我们来说非常重要。keep、prevent和stop后面接from doing sth都可以表示阻止某人做某事，本句中from是介词，后面接名词或者动名词做宾语，故选D。
