應(yīng)該是My mother often washes clothes on Sunday. often表示經(jīng)常,所以用一般現(xiàn)在時(shí).
It has snowed for two days, and the roads will be blocked if it won't stop soon.
這里有has,你就不能再用is了,動(dòng)詞只有一個(gè).這是一個(gè)時(shí)態(tài)混合的句子,前半句是現(xiàn)在完成時(shí),表示過去的情況影響到了現(xiàn)在,說明雪還沒有停. 后半句是意思是如果雪不停的話,道路將被封堵.是將來時(shí).那我這句話對(duì)不對(duì)？不對(duì)的話清幫我修改一下謝謝。我已經(jīng)幫你改了呀。
