I'm learning about -でしょう (deshou)、-かもしれない (kamoshirenai)、and -かな (kana). I have to fill in the blanks but the sentences seem strange so I must not be interpreting them correctly. I understood the first few sentences on the homework but not these. Please help if you can. I'm not trying to get only answers but understanding, thanks (^_^)

あの男の学生は日本語のきょうがしょをともっていうか ら、きっと___________________でしょう。
Ano otoko no gakusei wa nihongo no kyougasho wo tomotte iru kara, kitto_________ deshou.

It sounds to me like "That male student is burning his japanese textbook so, surely he's (or it's) ________" But that sounds crazy lol

今日は、とても寒くて、くもがたくさん___________から、� ��るは_________かもしれませんね。
Kyou wa, totemo samukute, kumo ga takusan ______ kara, yoru wa ______ kamoshiremasen.

"Today, and its very cold, clouds will probably _______ therefore, the night might _______." I have no idea if this is close or what to put in the blanks.

山下さんはスポーツが上手_______から、　きっとテニス� �_______でしょう。
Yamashita-san wa supootsu ga jouzu______kara, kitto tenisu mo _____ deshou.

"Yamashita is good at sports _______ therefore, surely probably ______ tennis too." Again that's my interpretation and I have no idea what to put in the blanks.

小川さんは、ねむそうですね。たくさんしゅくだいが___ _____から、きのうのよるはぜんぜん___________かもしれな� �ね。
Ogawa-san wa, nemu sou desu ne. Takusan shukudai ga ______ kara, kinou no yoru wa zenzen _____ kamoshirenai ne.

“Ogawa is sleeping, huh? His homework probably _______ so, last night probably _______ not at all.” I have no clue about this one either.

Thanks if you can help to guide me on the right track or help me translate them better. (T_T)
