Question

—Would you like to climb mountains with me this Sunday?
—I’d love to. But I _______ play table tennis against Class Three.

A．am going

B．am going to

C．am

D．going to

Answer 1

B

试题分析：根据上文时间状语可知下文说的是将来发生的动作，be + going +to+do，表示将来发生的动作。故选B.
点评：be going to结构表示将来计划打算发生的事情，常与this Sunday，next Sunday等时间状语搭配使用，应注意区分。
