of,animals,there will be no killing in nature.,【,解析】本句是一个含if引导条件状语从句,复合句，应遵照“主将从现”标准，即主句,时态用普通未来时，从句用普通现在时。,there be结构是固定句型，其普通现在时形式,为“There is/are.”。空后所表示在意义上为,单数，故填is。,第24页,3.依据上下文已经有时态信息确定时态,有些试题即使看起来没有时间状语做提醒，也不是复合句，不过上下文动作存在着显著时间次序，所以可依据上下文已经有时态来判断空格处所要选取时态(尤其注意and,but,while等连词连接成份要保持时态上统一)。,第25页,例：,The girls were r_ their bikes,around the lake while the boys were,running.,【解析】分析句子结构可知，此处应填动词与,were组成谓语。bike常与动词ride搭配，表示,骑自行车。依据while后“were running”可知,该句使用了过去进行时。结合句意和空格之前,已经给出were，可知应填现在分词riding。,第26页,1.I will _(boil)some
