问题 The sky was so clear in fact that the communications crew and recovery team could watch the balloon______ to its maximum altitude with the naked eye.
选项 A、hike
B、elevate
C、escalate
D、ascend
答案 D
解析 语义连贯题。气球的上升是缓慢地、逐渐地，ascend 指物体逐渐或继续上升。[A] hike作不及物动词时意为“升起”，尤指从某处升起，如 My coat had hiked up in the back．(我外套后面鼓了起来)[B]elevate 指举起或抬起某物；[C]escalate“逐步上升，逐步增强”，不指事物海拔的升高。
