guess

1.I guess是美国英语，作“我想”或“我以为”解，用来使语气婉转些，如I guess he cannot do it比He cannot do it婉转。

2.guess有时作“猜”解，不一定猜着，后面加上了at便含有“猜猜看”的意思，如I cannot even guess (at) his age和I can only guess (at) the height of the pagoda。但guess用在answer, riddle, thought等词的前面作“猜着”解。例如：She guessed the right answer at once. He failed to guess the riddle. 和I am sure I can guess your thoughts.
