问题 In some places leaves will fall off the trees before they change colors in the autumn.
Broadleaved plants in the temperate zones begin to shed their leaves before winter because they cannot______.

选项

答案endure winter

解析 由题干中的Broadleaved plants定位到第五个小标题下末段;再由shed和in the temperate zones定位到该段的倒数第1、2句话Tissues unable to endure winter must be sealed off and shed to ensure the plant’s continued survival. Thus leaf fall precedes each winter in the temperate zones.此处需要填入动词性成分。题干中的shed their leaves before winter与原文中的leaf fall precedes each winter属同义转述;tissues unable to endure winter指的就是leaves of Broadleaved plants。故答案为endure winter。
