嘿嘿,又見到你啦!
1 請走在馬路內側
Please walk on the inside lane of the road
Please walk in the inside lane of the road
我比較喜歡第二句
2 請靠馬路右側 走路 / 騎車 (自行車)
Please walk on the right side of the road
Please bike on the right side of the road (bike 做動詞)
或
Please ride your bike on the right side of the road
3 不要長時間走在馬路中間
Do not stay or walk in the middle of the road for too long
我覺得 for too long 在這句子裏是宂餘的,可以省略.
4 請把自行車扶起來
Please pick the bike up.
5 請把剛才滑到的老人扶起來
Please help up the elderly gentleman who just fell.
Please help the elderly gentleman,who just tripped,get up.
第一句比較簡潔.
