The whole hall hummed from its hundred ventilators and vibrated with the turn of the great engines below . 整个大厅里充斥着上百个通风器的嗡鸣声,并且由于大厅下面转动着巨大蒸气机而颤动着。
If you happen to hear a humming sound and see a flash of color whiz by . . . who knows 如果你偶然听到嗡鸣声,又瞥见一道缤纷色彩掠过…谁知道呢?
To protect ourselves from the hungry mosquitoes , we wrapped ourselves completely with our sleeping bags . the summer heat was intolerable , but it would have been worse to let the mosquitoes feast on us the whole night long . even more irritating was their dull buzzing sound , which reminded us of bomber planes 为了免受无数蚊子的叮咬,我们每个人都用睡袋将全身从头到脚地包裹起来,尽管暑热难耐,但总比整晚喂蚊子来得好,更何况蚊子的嗡鸣声就像轰炸机一样,轰得人无法忍受。
