Honestly, a lot of this depends on context. Some of these could also be different tenses, as you can see by the differences between my and Certainly's responses. - while Clarke (left) the newsroom Lois (called) the police [I put this in past tense, Certainly used present] - salima we (thought of naming) the baby rawia what (do you think about) that name - it's (sounding) pretty [This is different because it's = it is, and the tense is basically already given, although this is not a common phrase] - please do not forget (to book) a chair for me next to you in the cinema tomorrow [I agree with certainly – it makes more sense to say save in this context] - May (has taken) photos ever since her parents (bought) her a snapshots of friends and family but then she (changed) to black and white - lately she (has shot) a lot of nature photographs [once again, I used a different tense than Certainly] - I'm writing this letter (to express) my anger and disappointment at (having) fast-food chains in the dining halls [This just flows better than Certainly's version]

- While clarke *leaves* the newsroom, lois *calls* the police - Salima, we *named* the baby Rawia. What *do you think* about that name - It sounds pretty - Please do not forget *to book* ( I would say "to reserve" or "to save" ) a chair for me next to you in the cinema tomorrow - May (the name "May", not the auxiliary verb) *has taken* photos ever since her parents *bought* her snapshots of friends and family, but then she *changed* to black and white. -Latelly she *shoots* a lot of nature photographs -I'm writing this letter *to express* my anger and disappointment *I had at* fast-food chains in the dining halls. I put the correct tenses in **'s, as well as corrected some other outlying grammatical errors within the sentences. Let me know if you need any explanation as to which words I chose. Hope this helps :)
