Question

【题目】I think _______ a foreign language is not easy. You should _______ it often.
A.to learn; to practice
B.learning; practice
C.learn; practicing
D.learns; to practice

Answer 1

【答案】B
【解析】句意：我认为学习一门外语是不容易的。你应该经常练习。I think是插入语此空是缺少主语成分，动名词做主语，故用动名词形式learning。第二空谓语情态动词后面的实意动词要用原形，所以should之后用动词原形practice，故选B。
