penjelasan: setiap negative sentence itu pakai not, dan untuk interrogative biasanya tata letak to be-nya jadi di depan.

jawaban:

a.

-) rina did not (bisa ditulis didn't) winthe english speech competition last week

?) did rina win the english competition last week?

b.

-) dina's sister didn't speak english fluently yesterday

+) did dina's sister speak english fluently yesterday?

note: karena ini past tense, kita pakai did ya, terus pas pakai did verbnya jadi verb satu lagi..

c.

-) bima was not (wasn't) clever student in his class

?) was bima clever student in his class?

d.

-) many people were not (weren't) happy to attend the party last night

?) were many people happy to attend the party last night?

note: was digunakan untuk subjek tunggal, seperti bima tadi. sedangkan were digunakan untuk subjek yang banyak (jamak) contohnya people

e.

-) i didn't drink a cup of milk two hours ago

?) did i drink a cup of milk two hours ago?

semoga membantu!
