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 正确答案是B,可是think后面不是应该＋to do sth.么
答
本题答案为B项.句意：我认为学习一门外语不容易.你应该经常练习.本句补全为：I think (that) learning/ to learn a foreign language is not easy.You should practice it often.由此可见,think 后为宾语从句,而设空处为非谓语动词作主语,不定式,动名词都可以作主语.第二空should为情态动词,后面需加不带to的不定式,即：动词原形.综上所述答案为B项.
