第8题：

［A］ use ［B］ turn ［C］ give ［D］ back

正确答案：C

本题考查短语动词辨析。空格处填入的动词与副词up搭配构成短语动词。use up意为“用完，耗尽”，如He used up all the money.（他把所有的钱都花光了。）turn up意为“开大（音量、热量等）；找到，发现”，如The farmer turned up a human skull while ploughing the field.（那个农民犁地时挖出一个人类的头颅骨。）give up意为“放弃”，常接动名词作宾语，如give up smoking（戒烟）。back up意为“支持，援助”，如The rebels backed up their demands with threats.（反叛者以恐吓手段要挟。）根据上下文意，神奴役人类，人被创造出来后神就不用再劳动。因此［C］正确。
