Antibiotics overprescribed 美國人抗生素使用過多

Escalator behaviour trial 倫敦地鐵扶梯試行“只站不走”

文字稿

A new study has concluded that antibiotics are prescribed inappropriately in nearly a third of cases in the United States. It's estimated 47 million unnecessary prescriptions are given out every year – most are for viral illnesses that don't even respond to antibiotics.

一項新研究作出的結(jié)論說，在美國，有近三分之一的情況下抗生素被不合理地開給病人使用。據(jù)估算，每年有四千七百萬不必要的抗生素處方被開出，其中絕大多數(shù)都是為了使用抗生素治愈病毒性疾病，而病毒性疾病本身對抗生素并不會有任何反映。

Now if you've ever visited London you might have learnt the long-standing tradition of escalator etiquette where if you want to stand you stay on the right and if you want to walk up you walk on the left. Well, an experiment by Transport for London has found that congestion is eased when commuters are encouraged to stand on both sides. The trial is being extended for six months.?

如果你曾來訪過倫敦，那么你很可能已經(jīng)對由來已久的“扶梯禮儀”有所了解。在倫敦，乘坐自動扶梯時，站立靠右，行走靠左。近日，倫敦交通局推出的一個試驗發(fā)現(xiàn)上班族在搭乘扶梯時只站不走的話，可以幫助緩解高峰期扶梯客流擁堵情況。此提議的試行期已經(jīng)被延長至六個月。
