The Chinese are looking forward to the first ________ to land on the moon after Yang Liwei’s successful trip to space．

A.measure

B.attempt

C.purpose

D.desire

答案及解析： B

句意：在杨利伟成功的宇宙之行后，中国人一直盼望着登陆月球的首次尝试。attempt试图，努力；measure手段；purpose意图；desire愿望。根据句意，谓语动词look forward to(盼望)的宾语不可能是measure, purpose和desire。
