Grammar B
unless意为“除非，如果不”，可用来引导条件状语从句。unless引导的从句既可以放在主句之前也可以放在主句之后。当从句位于主句之前时，常用逗号与主句隔开。e.g. He wn’t cme t the party unless yu invite him.如果主句是一般将来时态，则unless 引导的从句的时态通常用一般现在时表将来。Smetimes we can use if ... nt t replace unless. e.g. The situatin will cntinue unless humans stp hunting them fr their fur and bnes. = The situatin will cntinue if humans d nt stp hunting them fr their fur and bnes.
The unless-clause can cme first r after the main Unless yu try yur best, yu will nt realize yur dream. Yu will be late unless yu leave right nw.在unless引导的条件状语从句中，主句也可以含有情态动词或祈使句。e.g. He cannt see clearly unless he wears glasses. Dn’t tuch the machine unless the teacher allws yu t.
