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

試題分析：keep保持，堅持；prevent阻止；stop阻止。句意：我們應該阻止人們砍伐太多的樹木、——我同意你的看法。樹木對我們來說非常重要。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是介詞，后面接名詞或者動名詞做賓語，故選D。
