9、e，but sometimes I go to school by bus. 我經(jīng)常騎自行車上學(xué)，但有時乘公共汽車去。 4. sometimes意為“有時，表示發(fā)生的頻率最小。sometimes一詞在書寫時要十分小心，假設(shè)分開寫成 some times就成了“好幾次，數(shù)次。如： He has lunch in the factory sometimes. 他有時在工廠吃午飯。 I read this story some times. 這個故事我讀過好幾次了。摘自 英語輔導(dǎo)報 How often do you do sports And you What do you like doing o
