Question

Compared with the nervousness of driving in the rain or snow, it is_______ to sit in a train and look out of the windows without any worry of bad weather.
A．more tired B．less tiring C．less tired D．even more tiring

Answer 1

答案：A

解析：B、C不符合语境；tired意为“疲劳的,累的”，主语是人；tiring意为“麻烦的,无聊的”，主语是物。句意为“与在雨中或者雪中驾驶的神经紧张相比，坐在屋里没有对天气的任何顾虑地透过窗户看雨要更累。”故选A。

Answer 2

B
it is less tiring to do sth此句中it为形式主语，替代动词不定式to do ，形容词修饰to do不修饰人，所以用tiring
