法功能走近高考考拓展閱讀讀接下來,約翰·斯諾調(diào)查查了這兩兩條街的的水源情情況。他他發(fā)現(xiàn),水是從河河里來的的,而河水被被倫敦排排出的臟臟水污染染了。他他馬上叫叫寬街上上驚慌失失措的老老百姓拆拆掉水泵泵上的把把手。這這樣,水泵就用用不成了了。不久久,疫情就開開始得到到了緩解解。他證證明了,霍亂是由由病菌而而不是由由氣團傳傳播的。。在倫敦的的另一個個地區(qū),他從兩個個與寬街街暴發(fā)的的霍亂有有關(guān)聯(lián)的的死亡病病例中發(fā)發(fā)現(xiàn)了有有力的證證據(jù)。有有一位婦婦女是從從寬街搬搬進來的的,她特別喜喜歡那里里的水,每天都要要派人從從水泵打打水運到到家里來來。她和和她的女女兒喝了了這種水水,都得了霍霍亂而死死去。有有了這個個特別的的證據(jù),約翰·斯諾就能能夠肯定定地宣布布,這種被污污染了的的水?dāng)y帶帶著病菌菌。為了防止止這種情情況的再再度發(fā)生生,約翰·斯諾建議議所有水水源都要要經(jīng)過檢檢測。自自來水公公司也接接到指令令,不能再讓讓人們接接觸被污污染的水水了。最最終,“霍亂王”被打敗了了。重點詞匯匯重點句型型重點語法法功能走近高考考拓展閱讀讀詞海拾貝貝1.attend/??tend/vt.照顧;護理;出席;參加2.physician/fI
