答案解析：

1.B (rising) 解析：根据句意“太阳从地平线上升起”，应该选择“rising”表示“升起”的动作。选项A“sank”意为“下沉”，与句意不符。
2.D (alive) 解析：句子描述街道充满了声音，应该选择“alive”表示“充满生机的”。选项C“awake”通常用来形容人醒着的状态，不适用于描述街道。
3.F (customers) 解析：市场熙熙攘攘，人们正在购物，所以应该是“customers”（顾客）在市场中。选项E“busy”是形容词，不能直接填入空白处。
4.C (awake) 解析：句子说John准备开始他的一天，所以应该选择“awake”表示“醒着的，清醒的”。选项B“rising”虽然也是动词，但在此处不符合语境。
5.E (busy) 解析：句子提到John知道这一天将会是忙碌和具有挑战性的，所以应该选择“busy”作为形容词描述这一天。
6.G (tasked) 解析：句子说John和他的同事被指派完成一座新建筑，所以应该选择“tasked”表示“被指派任务”。
7.H (precise) 解析：句子说他们工作勤奋，确保每一个细节都是精确的，所以应该选择“precise”作为形容词描述细节。
8.I (completed) 解析：句子说他们看着他们的工作，感到自豪，所以应该是“completed”工作，即“完成的工作”。选项A“sank”和B“rising”在这里都不适用。
