回答如下:
【参考译文】首先,当在入睡时可能会出现有短暂中断或者减弱,因为睡眠者还在睡眠和醒之间进行波动以及他们不同生理控制机制.
句子语法结构分析如下:
状语:first(首先)
存在有句型引导词:There(无意义)
谓语:may be(也许有/可能有)
主语:a brief of cessation or reduction of breathing(一个短暂中断和减弱)
状语:when falling asleep(当在入睡时)
状语:as the sleeper waxes and wanes between sleep and wakefulness and their differing control mechanism
重点单词及短语解释如下:
【1】cessation停止,休止,中断
【2】reduction 减少;减弱;降低;缩小
【3】brief 简短的;短暂的
【4】breathing 呼吸;吸;呼
【5】sleeper 睡觉者

【8】fall asleep 入睡; 睡着;
【9】waxes and wanes 兴衰;盛衰;盈亏圆缺;渐强和渐弱
【10】between A and B
【10】differing controll mechanism 不同的生理控制机制
【备注:不同生理控制机制即:不同的睡眠生理机制和不同的醒着生理机制。】
A=sleep
B:wakefulness
C:their differing controll mechanism
ABC这三者属于并列关系
