with no frills=without frills
余分なものを省いた
with no thought of profit
採算を度外視して
with obstinacy
がんこに
with one assent
満場一致で
with [in] one bound
一躍,一跳びで
With one gulp he drained his glass.
彼は一口でグラスを飲み干した
with one stroke of the ax
おのの一撃で
with one voice
声を合わせて
with one's bare hands
素手で,丸腰で
with one's body extended on the grass
芝生の上で大の字になって
