Few things i learned in my profession

1) there is a plural form for crisis. It is "crises".

2) it seems there's no plural form for the word "tense" ( as in present tense, past tense)

3) (this is not a learning per se but more like an affirmation of previous knowledge)
you cannot explain your poverty. eg "sally explain her poverty" is a grammatically incorrect sentence. But you can say " sally explained for her poverty" or "sally explained the circumstances of her poverty".
Poverty is a STATE of being poor. Its a description. get it? hahah

4) "Teachers' bracelet" == a collection of rubber-bands around the wrist(s)
