Bob and Anna found a schoolbag at the park. Listen and write down the things in the schoolbag.
2a
Who do you think the owner of the school bag is
Why
Use “must” to show that you think something is probably true.(100%)
Use “might” or “could” to show that you think something is possibly true.(20%-80%)
Use “can’t ” to show that you are almost sure something is not true.(0%)
Listen again. Fill in the blanks.
2b
能用来表示推测的情态动词must, might, could, may, can't
确信程度大小：must > may > might
肯定和否定的推测：must（肯定） can't， couldn't (否定）
Use “must” to show that you think something is probably true.用“must ”来表明你认为某事很可能是符合事实的。
【词汇解读】probably 是副词，意为“很可能；大概”，表示推测，常位于助动词、情态动词、连系动词之后，行为动词之前，也可以直接位于句首。在否定句中，probably不能位于否定词之后，可放在否定词前或直接放在句首。probably的形容词形式为probable, 表示“可能发生的；很可能的”。
eg: This would probably be a good time to have a rest.
这很可能是休息的好机会。
I will come next week, probably on Friday.
我下周会来，可能在周五。
I probably didn’t try hard enough. 我也许努力得不够。
拓展
【辨析】probably , possibly , maybe与perhaps
probably 意为“很可能；大概”肯定意味最浓，相当于 most likely He will probably pass the exam.他很可能通过考试。
possibly 意为“可能；或许”，语气弱于probably,可与could 连用，表示委婉的请求，也可以can’t等否定词连用，用于加强语气，强调不可能。 This task is possibly the most difficult.这项任务也许是最难的。
maybe 意为“可能；也许”，语气不确定。常用于口语中，多位于句首。 Maybe he knows the truth.或许他知道真相。
perhaps 相当于maybe,但比maybe要正式，可位于句首，也可位于句中。 This is perhaps her best novel.这也许是她最好的小说。
